Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated: 1 00:01:14,157 --> 00:01:15,579 - It was more than a symbol. 2 00:01:15,580 --> 00:01:18,911 This was actually of our own creation. 3 00:01:25,877 --> 00:01:27,971 It is really true that you can only explore 4 00:01:27,972 --> 00:01:32,091 the solar system for the first time once. 5 00:01:32,092 --> 00:01:33,301 Voyager did that. 6 00:01:36,221 --> 00:01:38,431 - How could one be so lucky? 7 00:01:38,432 --> 00:01:40,935 It's a dream and it came true. 8 00:01:44,521 --> 00:01:45,896 - 50 years from now, 9 00:01:45,897 --> 00:01:49,108 Voyager will be the science project 10 00:01:49,109 --> 00:01:50,985 of the 20th century. 11 00:01:50,986 --> 00:01:51,828 The mission. 12 00:01:51,829 --> 00:01:52,867 The big mission. 13 00:01:57,826 --> 00:01:59,499 - We didn't imagine big enough 14 00:01:59,500 --> 00:02:01,954 and it opened our eyes to worlds, 15 00:02:01,955 --> 00:02:03,080 to real worlds. 16 00:02:17,846 --> 00:02:20,725 - It was an unworldly experience to fly through that 17 00:02:20,726 --> 00:02:23,064 small little window of space and time. 18 00:02:23,065 --> 00:02:24,649 It was absolutely astonishing that we 19 00:02:24,650 --> 00:02:26,113 were able to pull that off. 20 00:02:32,861 --> 00:02:33,908 - Oh come on now. 21 00:02:33,909 --> 00:02:36,908 - We created an artificially intelligent spacecraft 22 00:02:36,909 --> 00:02:38,866 that we hurled into space. 23 00:02:43,580 --> 00:02:45,127 - This may in the long run be 24 00:02:45,128 --> 00:02:48,125 the only evidence that we ever existed. 25 00:02:48,126 --> 00:02:49,673 When you know that about something 26 00:02:49,674 --> 00:02:51,295 you're working on, 27 00:02:51,296 --> 00:02:53,924 you treat it with great respect. 28 00:02:54,800 --> 00:02:56,928 - It's taking what you thought you knew 29 00:02:56,929 --> 00:02:59,720 and having it just spun around 30 00:02:59,721 --> 00:03:03,724 and you're in one universe in one moment, 31 00:03:03,725 --> 00:03:06,444 you're in a completely different universe the next. 32 00:03:07,771 --> 00:03:11,071 ♫ I'm wishing on a star ♫ 33 00:03:12,818 --> 00:03:16,288 ♫ To follow where you are ♫ 34 00:03:18,073 --> 00:03:21,498 ♫ I'm wishing on a dream ♫ 35 00:03:23,370 --> 00:03:26,874 ♫ To follow what it means ♫ 36 00:03:28,709 --> 00:03:31,752 ♫ And I wish on all the rainbows ♫ 37 00:03:31,753 --> 00:03:33,796 ♫ That I see ♫ 38 00:03:33,797 --> 00:03:35,640 - When it was just recently announced 39 00:03:35,641 --> 00:03:38,222 that Voyager One was interstellar space 40 00:03:38,223 --> 00:03:40,141 it was like humanity had just 41 00:03:40,142 --> 00:03:43,013 become an interstellar species. 42 00:03:43,014 --> 00:03:46,314 It was like knocking on eternity's door. 43 00:03:47,269 --> 00:03:49,021 - Voyager's on the other side of the solar system 44 00:03:49,022 --> 00:03:50,521 and it's billions and billions 45 00:03:50,522 --> 00:03:53,822 of miles from the nearest other human made object. 46 00:03:53,823 --> 00:03:57,027 ♫ But Darwin knew would be ♫ 47 00:03:57,028 --> 00:03:58,154 - Just think about the distance 48 00:03:58,155 --> 00:03:59,655 that Voyager's gone 49 00:03:59,656 --> 00:04:01,829 and the years that it's travelled to get there 50 00:04:01,830 --> 00:04:03,492 and it's still going. 51 00:04:03,493 --> 00:04:05,828 ♫ So far away from me ♫ 52 00:04:05,829 --> 00:04:07,126 - Voyager made it. 53 00:04:07,127 --> 00:04:11,000 Accomplished something no one dreamed it could do. 54 00:04:11,001 --> 00:04:13,675 - Every second it goes to another place 55 00:04:13,676 --> 00:04:16,505 where we have never been before. 56 00:04:16,506 --> 00:04:18,007 - It's all an escape trajectory. 57 00:04:18,008 --> 00:04:19,385 It's not coming back. 58 00:04:19,386 --> 00:04:22,136 It's just gonna keep going forever and ever, 59 00:04:22,137 --> 00:04:24,390 out into empty empty space. 60 00:04:25,474 --> 00:04:26,726 - Voyager takes the cake. 61 00:04:26,727 --> 00:04:28,102 It's the most audacious mission. 62 00:04:28,103 --> 00:04:30,195 Who'd have thought that we'd actually be able 63 00:04:30,196 --> 00:04:31,780 to do that in 1977? 64 00:04:33,148 --> 00:04:36,493 ♫ I'm wishing on a star ♫ 65 00:04:47,996 --> 00:04:49,538 - We knew a little, 66 00:04:49,539 --> 00:04:51,132 because you can't observe from the earth 67 00:04:51,133 --> 00:04:52,467 with telescopes. 68 00:04:54,836 --> 00:04:56,045 - It was big. 69 00:04:56,046 --> 00:04:56,888 No. 70 00:04:57,923 --> 00:04:59,675 Let's see, what did we know? 71 00:05:00,801 --> 00:05:03,260 We knew they were all gas giants. 72 00:05:03,261 --> 00:05:05,513 Mostly made up of hydrogen and helium 73 00:05:05,514 --> 00:05:07,973 and some methane on the outer planets. 74 00:05:07,974 --> 00:05:09,725 - We knew that there were winds on Jupiter, 75 00:05:09,726 --> 00:05:11,477 we knew about the great red spot on Jupiter, 76 00:05:11,478 --> 00:05:13,697 we knew that there was trapped radiation, 77 00:05:13,698 --> 00:05:16,315 so we knew there was a magnetic field. 78 00:05:16,316 --> 00:05:17,613 - We knew for example that Jupiter 79 00:05:17,614 --> 00:05:19,610 that there were four moons. 80 00:05:19,611 --> 00:05:21,784 Io, Europa, Ganymede, and Callisto going around. 81 00:05:21,785 --> 00:05:25,956 That's what convinced Galileo that Copernicus was right 82 00:05:27,202 --> 00:05:31,539 and that the Sun is the centre of the solar system. 83 00:05:31,540 --> 00:05:33,417 - Satellites of the outer planets, 84 00:05:33,418 --> 00:05:35,005 we knew that they were there because 85 00:05:35,006 --> 00:05:36,465 we could see them orbiting. 86 00:05:36,466 --> 00:05:38,930 But I think everyone figured they would be 87 00:05:38,931 --> 00:05:40,798 just battered ice balls. 88 00:05:40,799 --> 00:05:42,301 Kind of like the highlands of the moon. 89 00:05:42,302 --> 00:05:44,552 Nothing but impact craters. 90 00:05:44,553 --> 00:05:47,513 That view was so pervasive that they 91 00:05:47,514 --> 00:05:50,891 didn't even think to add any geologists 92 00:05:50,892 --> 00:05:52,685 to the Voyager mission. 93 00:05:52,686 --> 00:05:54,776 - For Saturn we knew about the rings 94 00:05:54,777 --> 00:05:57,365 and we knew about the major satellites. 95 00:05:57,366 --> 00:05:59,817 But hardly anything more than that. 96 00:05:59,818 --> 00:06:01,946 And it was all very fuzzy. 97 00:06:03,488 --> 00:06:06,537 Nobody had ever been to the outer planets to speak of. 98 00:06:06,538 --> 00:06:09,410 Pioneer had gone past Jupiter and Saturn 99 00:06:09,411 --> 00:06:11,960 but they had elementary camera. 100 00:06:13,498 --> 00:06:16,292 It didn't really show very many images. 101 00:06:16,293 --> 00:06:19,797 And instrumentation was not very advanced. 102 00:06:20,922 --> 00:06:23,218 - The Pioneer spacecraft were mostly" 103 00:06:23,219 --> 00:06:25,431 "Let's see, can we send something through 104 00:06:25,432 --> 00:06:26,969 "the asteroid belt, would it survive?" 105 00:06:26,970 --> 00:06:29,064 There were so many things that we take for granted now 106 00:06:29,065 --> 00:06:30,764 we knew nothing about. 107 00:06:30,765 --> 00:06:32,892 And the same was true for Uranus and Neptune. 108 00:06:32,893 --> 00:06:35,060 They're very far away. 109 00:06:35,061 --> 00:06:37,313 - I had been staring at these planets 110 00:06:37,314 --> 00:06:39,817 through some of the best telescopes on earth. 111 00:06:39,818 --> 00:06:43,241 And yet, all I could see was fuzzy blobs. 112 00:06:44,237 --> 00:06:48,532 - Uranus was a small bluish green dot in the telescope 113 00:06:48,533 --> 00:06:51,911 and Neptune was an even smaller bluish dot. 114 00:06:51,912 --> 00:06:53,621 And that's all. 115 00:06:53,622 --> 00:06:55,374 - Astronomers had worked pretty hard to know 116 00:06:55,375 --> 00:06:57,207 what physical makeup was. 117 00:06:57,208 --> 00:06:59,460 There was some basic characteristics. 118 00:06:59,461 --> 00:07:01,253 But their real nature 119 00:07:01,254 --> 00:07:04,798 in terms of weather, in terms of distribution 120 00:07:04,799 --> 00:07:08,510 of mass inside, what they were really made of, 121 00:07:08,511 --> 00:07:10,971 what the moons were like. 122 00:07:10,972 --> 00:07:12,019 We had none of that. 123 00:07:12,020 --> 00:07:14,600 Just little glimpses. 124 00:07:14,601 --> 00:07:16,194 - There's a limit to what you can learn 125 00:07:16,195 --> 00:07:18,938 just looking through a telescope from earth. 126 00:07:18,939 --> 00:07:21,815 There's theory but then there's unknowns. 127 00:07:21,816 --> 00:07:24,740 And we're researching the unknowns. 128 00:07:27,781 --> 00:07:30,578 - Human beings are a curious bunch. 129 00:07:30,579 --> 00:07:32,915 We wanna know what's around the corner. 130 00:07:32,916 --> 00:07:35,630 We have to go past that next bend in the road. 131 00:07:35,631 --> 00:07:38,290 So it's some sort of innate drive 132 00:07:38,291 --> 00:07:41,135 I think that we have as a species. 133 00:07:42,587 --> 00:07:45,089 - I think this innate desire to explore 134 00:07:45,090 --> 00:07:49,134 conveys an evolutionary advantage to us. 135 00:07:49,135 --> 00:07:51,637 We look to improve our circumstances. 136 00:07:51,638 --> 00:07:53,389 And I think that there is a feeling 137 00:07:53,390 --> 00:07:56,350 that our survival as a species 138 00:07:56,351 --> 00:07:59,395 is going to depend on our learning 139 00:07:59,396 --> 00:08:02,231 how to live on other worlds. 140 00:08:02,232 --> 00:08:05,111 - It's a very human thing to ask questions. 141 00:08:05,112 --> 00:08:06,699 It's a very childlike thing 142 00:08:06,700 --> 00:08:08,493 to ask a million questions. 143 00:08:09,739 --> 00:08:11,991 And some of us never grow up. 144 00:08:14,869 --> 00:08:17,121 - One of the key things that made this mission possible 145 00:08:17,122 --> 00:08:18,335 was gravity assist. 146 00:08:18,336 --> 00:08:20,958 That is when you fly by Jupiter, you turn the corner, 147 00:08:20,959 --> 00:08:22,835 and you take a little bit of Jupiter's 148 00:08:22,836 --> 00:08:24,545 orbital speed with you. 149 00:08:24,546 --> 00:08:25,963 Like a slingshot. 150 00:08:25,964 --> 00:08:29,343 So you better make sure Saturn's in the right place. 151 00:08:29,344 --> 00:08:31,552 - We were very fortunate 152 00:08:31,553 --> 00:08:34,304 that we had an alignment. 153 00:08:34,305 --> 00:08:36,515 - Jupiter, Saturn, Uranus, and Neptune 154 00:08:36,516 --> 00:08:37,392 would all line up. 155 00:08:37,393 --> 00:08:40,019 - It would go Jupiter boom, Saturn boom, 156 00:08:40,020 --> 00:08:42,563 Uranus boom, Neptune boom. 157 00:08:42,564 --> 00:08:44,440 - The planets had to be lined up in 158 00:08:44,441 --> 00:08:47,741 just the right way to allow one spacecraft to do that. 159 00:08:47,742 --> 00:08:50,779 - And that aligning up only occurs rarely. 160 00:08:50,780 --> 00:08:53,996 - It only happens like once every more than 100 years. 161 00:08:53,997 --> 00:08:56,120 - 175 years, something like that. 162 00:08:56,121 --> 00:08:58,042 - Once every 176 years. 163 00:08:59,330 --> 00:09:00,798 - The previous time it happened 164 00:09:00,799 --> 00:09:04,168 exploration was wooden sailing ships. 165 00:09:04,169 --> 00:09:07,337 - It was named The Outer Planets Grand Tour, 166 00:09:07,338 --> 00:09:10,217 and the cost of the mission was estimated to be 167 00:09:10,218 --> 00:09:13,177 in excess of a billion dollars. 168 00:09:13,178 --> 00:09:16,972 The NASA administrator went to the President, 169 00:09:16,973 --> 00:09:18,771 and he said "The last time the planets 170 00:09:18,772 --> 00:09:20,976 "were lined up like that, 171 00:09:20,977 --> 00:09:23,821 “President Jefferson was sitting at your desk, 172 00:09:23,822 --> 00:09:25,235 "and he blew it.“ 173 00:09:26,399 --> 00:09:30,575 So, Mr. Nixon laughed and said "All right, just do two.“ 174 00:09:32,363 --> 00:09:34,114 So, only two planets. 175 00:09:34,115 --> 00:09:36,909 And of course the price tag consequently 176 00:09:36,910 --> 00:09:38,833 was substantially less. 177 00:09:39,954 --> 00:09:43,957 But we all knew that the launch was in 1977 178 00:09:43,958 --> 00:09:47,878 which would be after Mr. Nixon's second term. 179 00:09:47,879 --> 00:09:49,597 And of course it turned out 180 00:09:49,598 --> 00:09:54,176 that his term ended a lot sooner than even he thought. 181 00:10:02,977 --> 00:10:04,650 - Voyager started as a project 182 00:10:04,651 --> 00:10:05,989 in July of 1972. 183 00:10:06,898 --> 00:10:08,696 And we had 11 scientific instruments, 184 00:10:08,697 --> 00:10:09,983 11 different teams. 185 00:10:09,984 --> 00:10:14,205 And the mission success was one spacecraft past Saturn. 186 00:10:15,115 --> 00:10:17,288 - But we knew right from the get go 187 00:10:17,289 --> 00:10:20,619 that we were going to try as hard as we could 188 00:10:20,620 --> 00:10:24,081 to extend the mission to go to Uranus and Neptune. 189 00:10:24,082 --> 00:10:26,426 - We selected trajectories to pick 190 00:10:26,427 --> 00:10:28,961 A target at Saturn that would give us 191 00:10:28,962 --> 00:10:30,420 an assist to Uranus. 192 00:10:30,421 --> 00:10:33,300 And so we designed that in from the beginning. 193 00:10:33,301 --> 00:10:36,135 We knew that we were endowing Voyager 194 00:10:36,136 --> 00:10:39,763 with the option if the chance was there to use it. 195 00:11:00,660 --> 00:11:03,125 - We didn't want to build anything into the design 196 00:11:03,126 --> 00:11:05,590 that would have prevented us from going further. 197 00:11:05,591 --> 00:11:08,750 So it was a mission within a mission. 198 00:11:20,221 --> 00:11:21,722 - The Golden Record really is the kind of 199 00:11:21,723 --> 00:11:24,641 heartbeat of the ship itself. 200 00:11:24,642 --> 00:11:26,940 The reason why it's going there, it's certainly exploring, 201 00:11:26,941 --> 00:11:30,065 but it's the lifeblood is that record. 202 00:11:32,692 --> 00:11:36,538 - I remember all the publicity Pioneer 10 and 11 spacecraft 203 00:11:36,539 --> 00:11:40,657 where they had some line drawings of a male and female form. 204 00:11:40,658 --> 00:11:42,284 And some people went absolutely bonkers. 205 00:11:42,285 --> 00:11:43,410 I don't know if you've seen it 206 00:11:43,411 --> 00:11:46,005 but it's the most innocent thing you can imagine. 207 00:11:46,006 --> 00:11:47,956 It caused a lot of commotion. 208 00:11:47,957 --> 00:11:49,583 Well I thought that was great. 209 00:11:49,584 --> 00:11:52,336 - Would you expect someone to find this record out there? 210 00:11:52,337 --> 00:11:54,004 Is there something out there? 211 00:11:54,005 --> 00:11:54,847 - Well nobody knows. 212 00:11:54,848 --> 00:11:56,929 One of the great unsolved questions is whether 213 00:11:56,930 --> 00:11:58,302 we're alone or we're. 214 00:11:58,303 --> 00:12:00,395 - Carl Sagan has become probably the best 215 00:12:00,396 --> 00:12:03,680 known scientist of the late 20th century. 216 00:12:03,681 --> 00:12:05,479 He was a working scientist. 217 00:12:05,480 --> 00:12:07,517 He played a key role in many 218 00:12:07,518 --> 00:12:10,229 of the NASA missions to the planets. 219 00:12:10,230 --> 00:12:11,901 Including the Voyager One. 220 00:12:11,902 --> 00:12:14,526 He's one of the scientists on the Voyager imaging team. 221 00:12:14,527 --> 00:12:16,696 But he also was the astronomer who was 222 00:12:16,697 --> 00:12:18,287 as much as any one person, 223 00:12:18,288 --> 00:12:21,907 made the study of extraterrestrial life credible. 224 00:12:21,908 --> 00:12:25,577 - The comment by a Thomas Carlisle, 225 00:12:25,578 --> 00:12:27,876 a somewhat crusty old fellow 226 00:12:29,123 --> 00:12:33,299 who upon thinking about the stars, a sad spectacle. 227 00:12:35,421 --> 00:12:40,259 “If they be inhabited, what a scope for misery and folly. 228 00:12:40,260 --> 00:12:43,804 “If they be not inhabited, what a waste of space.“ 229 00:12:44,931 --> 00:12:46,148 - Carl Sagan was a good friend of mine 230 00:12:46,149 --> 00:12:48,517 and I called him up and said, "Hey, would you 231 00:12:48,518 --> 00:12:50,852 "be willing to undertake, to come up with something 232 00:12:50,853 --> 00:12:52,479 "for us to put on the Voyager spacecraft?" 233 00:12:52,480 --> 00:12:54,564 He says "Yes, sure." 234 00:12:54,565 --> 00:12:57,487 And he told me he could it for 25,000 bucks. 235 00:12:57,488 --> 00:12:59,283 So I authorised him to go ahead and do it 236 00:12:59,284 --> 00:13:02,447 and I sort of was hands off at that point. 237 00:13:02,448 --> 00:13:04,416 The whole creation was his and this group 238 00:13:04,417 --> 00:13:06,535 that he put together. 239 00:13:06,536 --> 00:13:08,254 - They figured don't let this opportunity pass. 240 00:13:08,255 --> 00:13:11,293 You're gonna throw a message in a bottle into the ocean, 241 00:13:11,294 --> 00:13:12,586 put a message in it. 242 00:13:12,587 --> 00:13:16,213 And so they decided to put time capsules in those bottles. 243 00:13:16,214 --> 00:13:18,088 - And at first Carl thought they'd simply 244 00:13:18,089 --> 00:13:20,716 do another plaque, maybe with some more information. 245 00:13:20,717 --> 00:13:23,093 But Frank Drake, a brilliant man. 246 00:13:23,094 --> 00:13:25,267 Kind of a cross between Albert Einstein 247 00:13:25,268 --> 00:13:26,722 and Thomas Edison. 248 00:13:26,723 --> 00:13:28,976 Brilliant theoretical physicist, but also a very 249 00:13:28,977 --> 00:13:31,228 hands on kind of guy who can solve 250 00:13:31,229 --> 00:13:33,312 practical kinds of problems. 251 00:13:33,313 --> 00:13:34,984 He came up with the idea that for 252 00:13:34,985 --> 00:13:37,359 the same amount of weight and space, 253 00:13:37,360 --> 00:13:39,693 you could send a phonograph record. 254 00:13:42,280 --> 00:13:43,994 - The people who actually did the science 255 00:13:43,995 --> 00:13:45,866 part of Voyager are always jealous and mad 256 00:13:45,867 --> 00:13:48,082 because the Golden Record gets more attention 257 00:13:48,083 --> 00:13:49,916 than all the wonderful things they did 258 00:13:49,917 --> 00:13:52,381 exploring the outer planets of the solar system. 259 00:13:52,382 --> 00:13:54,374 Except Pluto and all that. 260 00:13:54,375 --> 00:13:58,128 But the main attention goes to the Golden Record. 261 00:13:58,129 --> 00:14:00,969 Because of the aura that surrounds anything to do 262 00:14:00,970 --> 00:14:03,467 with extraterrestrial intelligent life, 263 00:14:03,468 --> 00:14:04,970 any kind of effort to contact 264 00:14:04,971 --> 00:14:07,763 extraterrestrial life is more fascinating 265 00:14:07,764 --> 00:14:09,107 than knowing the chemical makeup 266 00:14:09,108 --> 00:14:11,433 of a mineral on Mars or something. 267 00:14:13,186 --> 00:14:15,776 - The record is an old-style LP recording. 268 00:14:15,777 --> 00:14:17,862 The only difference is it's on metal, 269 00:14:17,863 --> 00:14:20,447 and that's so it will last a long time. 270 00:14:20,448 --> 00:14:22,069 - And it was recorded at half-speed 271 00:14:22,070 --> 00:14:24,863 so that gave us two hours of total time. 272 00:14:24,864 --> 00:14:26,740 An hour and a half of it was devoted to music 273 00:14:26,741 --> 00:14:29,159 and the other half hour contains 274 00:14:29,160 --> 00:14:31,124 all of the other data on the record, 275 00:14:31,125 --> 00:14:34,373 the natural sounds of Earth, the spoken greetings, 276 00:14:34,374 --> 00:14:37,417 and the encoded photographs of Earth. 277 00:14:37,418 --> 00:14:39,169 - One of the first questions a lot of people ask 278 00:14:39,170 --> 00:14:41,423 is, well, they'll never figure out how to play it. 279 00:14:41,424 --> 00:14:44,883 And in fact, we included a cartridge and stylus 280 00:14:44,884 --> 00:14:46,431 in the package with the record, 281 00:14:46,432 --> 00:14:48,470 and the drawing on the cover 282 00:14:48,471 --> 00:14:50,064 of the record shows the method 283 00:14:50,065 --> 00:14:54,351 by which the stylus is to be placed on the record. 284 00:14:54,352 --> 00:14:55,729 - Maybe what's written on it 285 00:14:55,730 --> 00:14:58,149 will seem like kindergarten scribbles to them, 286 00:14:58,150 --> 00:15:00,399 but they should be able to figure it out 287 00:15:00,400 --> 00:15:01,868 if they've got some smart minds 288 00:15:01,869 --> 00:15:03,819 or whatever's in their heads, 289 00:15:03,820 --> 00:15:05,570 if they even have heads. 290 00:15:05,571 --> 00:15:07,699 - The Voyager launched at the 100th anniversary 291 00:15:07,700 --> 00:15:10,620 of the development of the phonograph record by Edison. 292 00:15:10,621 --> 00:15:12,712 And so it was a natural medium to put 293 00:15:12,713 --> 00:15:14,413 the information on. 294 00:15:14,414 --> 00:15:15,711 But what I find interesting is 295 00:15:15,712 --> 00:15:19,209 to protect it from the dust and tiny particles 296 00:15:19,210 --> 00:15:22,254 of the journey, they put a cover over it. 297 00:15:22,255 --> 00:15:24,678 And on the cover was engraved 298 00:15:26,050 --> 00:15:30,053 the location of earth, our solar system 299 00:15:30,054 --> 00:15:34,141 in terms of it's direction from different pulsars. 300 00:15:34,142 --> 00:15:35,437 - A lot of people would say, "Well why would you do that?" 301 00:15:35,438 --> 00:15:36,275 I said, "What do you mean?“ 302 00:15:36,276 --> 00:15:38,237 They said “Well why would you announce where you are?" 303 00:15:38,238 --> 00:15:39,855 'Cause there are aliens out there that 304 00:15:39,856 --> 00:15:42,234 probably raid planets and use them for food, 305 00:15:42,235 --> 00:15:44,276 or eat the people, or make them slaves. 306 00:15:44,277 --> 00:15:46,075 If they find it, their technology is probably 307 00:15:46,076 --> 00:15:47,112 more advanced than ours. 308 00:15:47,113 --> 00:15:48,328 They'll come here and destroy it. 309 00:15:48,329 --> 00:15:49,915 So why would you do something like that? 310 00:15:49,916 --> 00:15:52,576 So if somebody did find it they would be thinking that way 311 00:15:52,577 --> 00:15:54,830 and they said, "Why would these people expose themselves 312 00:15:54,831 --> 00:15:58,457 "to our veracious appetites or whatever it is. 313 00:15:58,458 --> 00:16:01,007 "They must be very altruistic.“ 314 00:16:04,380 --> 00:16:07,382 - The chance that advanced intelligence 315 00:16:07,383 --> 00:16:10,218 beyond us would detect "Oh, hey, 316 00:16:10,219 --> 00:16:14,556 "there is a radiating body coming into our area, 317 00:16:14,557 --> 00:16:18,232 "let's go out and find out what this bottle in the ocean, 318 00:16:18,233 --> 00:16:20,520 “what message it might have." 319 00:16:20,521 --> 00:16:22,899 Now is that a grand mystery? 320 00:16:24,442 --> 00:16:25,284 Whoa! 321 00:16:27,153 --> 00:16:29,076 - Well that brings up the whole question, 322 00:16:29,077 --> 00:16:31,948 is there anybody out there? 323 00:16:31,949 --> 00:16:32,791 Listen, 324 00:16:34,160 --> 00:16:36,703 there are give or take 325 00:16:36,704 --> 00:16:40,040 200 billion stars in the Milky Way Galaxy. 326 00:16:40,041 --> 00:16:42,715 There are about 200 billion galaxies in the universe. 327 00:16:42,716 --> 00:16:45,921 Or at least in the universe we know about. 328 00:16:45,922 --> 00:16:48,215 - It's a pretty small spacecraft 329 00:16:48,216 --> 00:16:51,092 and it's a pretty big universe. 330 00:16:51,093 --> 00:16:53,303 If you take a piece of sky 331 00:16:53,304 --> 00:16:56,103 the size of a soda straw up there 332 00:16:57,558 --> 00:16:59,184 in the Big Dipper, 333 00:16:59,185 --> 00:17:02,485 in that tiny piece of what we thought was blank sky 334 00:17:02,486 --> 00:17:04,940 was thousands of galaxies. 335 00:17:04,941 --> 00:17:06,942 And each one of those galaxies 336 00:17:06,943 --> 00:17:09,742 is filled with billions of stars. 337 00:17:10,780 --> 00:17:11,905 That's just the soda straw, 338 00:17:11,906 --> 00:17:13,996 and now you imagine the whole sky 339 00:17:13,997 --> 00:17:16,119 filled with thousands upon thousands 340 00:17:16,120 --> 00:17:17,582 upon thousands of galaxies. 341 00:17:17,583 --> 00:17:19,626 Each of which is billions of billions of stars. 342 00:17:19,627 --> 00:17:22,876 There's a lot of possibility out there. 343 00:17:26,462 --> 00:17:29,428 - If you took a grain of sand and put it on the table, 344 00:17:29,429 --> 00:17:31,675 and if that were the size of the Sun, 345 00:17:31,676 --> 00:17:33,891 then the earth would be about an inch away. 346 00:17:33,892 --> 00:17:35,262 And it would be microscopic. 347 00:17:35,263 --> 00:17:37,357 And the entire solar system would fit on a table 348 00:17:37,358 --> 00:17:38,691 six feet across. 349 00:17:39,559 --> 00:17:40,854 Think about the next star. 350 00:17:40,855 --> 00:17:42,897 The next star would be another grain of sand. 351 00:17:42,898 --> 00:17:44,941 How far away from that solar system 352 00:17:44,942 --> 00:17:46,316 would you have to put that? 353 00:17:46,317 --> 00:17:50,032 And it turns out to be about seven and a half miles away. 354 00:17:50,033 --> 00:17:52,529 It's absolutely remarkable how much space 355 00:17:52,530 --> 00:17:56,575 there is between the stars and between the planets. 356 00:17:56,576 --> 00:17:59,578 - The distances are almost unfathomable. 357 00:17:59,579 --> 00:18:01,126 These were the fastest spacecraft 358 00:18:01,127 --> 00:18:04,499 that had ever been built and launched and flown, 359 00:18:04,500 --> 00:18:05,968 and they're travelling 360 00:18:05,969 --> 00:18:07,883 at 10 miles per second. 361 00:18:09,797 --> 00:18:11,344 You wouldn't even see it, right? 362 00:18:11,345 --> 00:18:12,841 And yet, even at those 363 00:18:12,842 --> 00:18:16,553 unfathomable by Earth standard speeds, 364 00:18:16,554 --> 00:18:18,555 it takes decades, 365 00:18:18,556 --> 00:18:22,732 decades to get out there into the outer solar system. 366 00:18:24,395 --> 00:18:25,520 - We don't have any problem putting 367 00:18:25,521 --> 00:18:26,896 the spacecraft through the Asteroid Belt 368 00:18:26,897 --> 00:18:28,319 and yet at one time people think god 369 00:18:28,320 --> 00:18:30,444 that you were gonna crash into an asteroid. 370 00:18:30,445 --> 00:18:34,160 There's not very much chance of crashing into an asteroid. 371 00:18:34,161 --> 00:18:36,374 It's just a lot of room out there. 372 00:18:36,375 --> 00:18:37,537 A lot of room. 373 00:18:39,076 --> 00:18:40,544 - If you wanna realise how empty our galaxy is, 374 00:18:40,545 --> 00:18:42,829 the nearest galaxy to our own is Andromeda, 375 00:18:42,830 --> 00:18:44,082 it's about two million light years away. 376 00:18:44,083 --> 00:18:46,833 It's on a collision course with us right now. 377 00:18:46,834 --> 00:18:47,879 And in five billion years 378 00:18:47,880 --> 00:18:49,967 that galaxy's going to collide with our own. 379 00:18:49,968 --> 00:18:51,384 And you might say, oh, no, oh, no, 380 00:18:51,385 --> 00:18:52,802 but it turns out, 381 00:18:53,674 --> 00:18:56,473 space is, even in our galaxy, it's mostly empty space. 382 00:18:56,474 --> 00:18:58,595 When our two galaxies collide, 383 00:18:58,596 --> 00:19:01,190 almost no stars will hit any other star. 384 00:19:01,191 --> 00:19:03,266 It's mostly empty space. 385 00:19:03,267 --> 00:19:05,315 So Voyager is likely to continue throughout 386 00:19:05,316 --> 00:19:07,729 our galaxy for potentially millions 387 00:19:07,730 --> 00:19:11,858 or maybe even billions of years without a collision. 388 00:19:11,859 --> 00:19:16,279 - I have a hard time with really long geological timeframes. 389 00:19:16,280 --> 00:19:20,033 You just can't get your hands around how 390 00:19:20,034 --> 00:19:22,503 10s of millions of years, what that really means. 391 00:19:22,504 --> 00:19:25,497 And distances, astronomical distances. 392 00:19:25,498 --> 00:19:28,338 - Yeah, once you start getting into the astronomical scales, 393 00:19:28,339 --> 00:19:30,210 our solar system is pretty tiny, 394 00:19:30,211 --> 00:19:32,754 and so this adventure of Voyager 395 00:19:32,755 --> 00:19:35,674 which seems so remote and distant 396 00:19:35,675 --> 00:19:38,176 for this little spacecraft to go out 397 00:19:38,177 --> 00:19:41,846 to the giant planets is really just exploring 398 00:19:41,847 --> 00:19:44,849 the tiniest closest neighbourhood 399 00:19:44,850 --> 00:19:47,694 when you start thinking about cosmic scales. 400 00:19:58,072 --> 00:19:59,119 - The spacecraft were built 401 00:19:59,120 --> 00:20:00,786 at the Jet Propulsion Laboratory. 402 00:20:00,787 --> 00:20:02,456 It's a federal research centre 403 00:20:02,457 --> 00:20:06,581 that's part of Cal-Tech and they build spacecraft. 404 00:20:07,832 --> 00:20:09,628 One of the things I just admire most 405 00:20:09,629 --> 00:20:11,671 about the engineers who built Voyager 406 00:20:11,672 --> 00:20:13,342 is that they're always thinking about 407 00:20:13,343 --> 00:20:16,339 the most improbable things happening. 408 00:20:16,340 --> 00:20:17,340 You know, you want to take those people 409 00:20:17,341 --> 00:20:18,508 on a camping trip with you 410 00:20:18,509 --> 00:20:19,556 because they will think of. 411 00:20:19,557 --> 00:20:20,891 Well, you've got to bring, 412 00:20:20,892 --> 00:20:22,011 what if these bugs come out, 413 00:20:22,012 --> 00:20:23,226 what if the tent gets flooded, 414 00:20:23,227 --> 00:20:24,893 what if you run out of gas, 415 00:20:24,894 --> 00:20:26,891 what if you can't start the fire, you know. 416 00:20:26,892 --> 00:20:28,438 They're the what if people. 417 00:20:28,439 --> 00:20:31,527 And when you're sending something out into space 418 00:20:31,528 --> 00:20:33,240 you can't go do a service call, 419 00:20:33,241 --> 00:20:34,858 you can't bring it back, 420 00:20:34,859 --> 00:20:36,192 so your what if list 421 00:20:36,193 --> 00:20:38,570 had better be like that long 422 00:20:38,571 --> 00:20:41,740 or you're not going to be able to survive. 423 00:20:47,371 --> 00:20:49,247 - These projects begin 424 00:20:49,248 --> 00:20:52,459 with a conceptualization period. 425 00:20:52,460 --> 00:20:56,880 How feasible is it for us to do thus and so? 426 00:20:56,881 --> 00:21:00,304 We didn't know what the spacecraft was gonna look like. 427 00:21:00,305 --> 00:21:01,974 How do we arrange a spacecraft? 428 00:21:01,975 --> 00:21:05,513 How do we take the communications system, 429 00:21:05,514 --> 00:21:09,350 this large 12-foot diameter fixed antenna, 430 00:21:09,351 --> 00:21:13,730 and arrange it relative to the propulsion system? 431 00:21:13,731 --> 00:21:17,110 The spacecraft took on the dimension of being a child, 432 00:21:17,111 --> 00:21:20,612 and our design teams, you know, were like kind of parents. 433 00:21:20,613 --> 00:21:24,365 This was actually a nurturing process. 434 00:21:24,366 --> 00:21:25,950 Bringing that child, 435 00:21:25,951 --> 00:21:28,124 if you will, into reality. 436 00:21:31,957 --> 00:21:34,378 - All spacecraft were made basically of the same things. 437 00:21:34,379 --> 00:21:36,716 Silicon and aluminium, that's about it. 438 00:21:36,717 --> 00:21:38,463 You know, that's probably 95% of it. 439 00:21:38,464 --> 00:21:40,387 Silicon and aluminium is cheap 440 00:21:40,388 --> 00:21:44,260 until you start making stuff out if it, you know. 441 00:21:44,261 --> 00:21:46,137 - The spacecraft of course is quite primitive 442 00:21:46,138 --> 00:21:47,230 by modern day standards. 443 00:21:47,231 --> 00:21:49,682 We have three computers on board. 444 00:21:49,683 --> 00:21:51,893 Their total memory is about, 445 00:21:51,894 --> 00:21:55,730 240,000 times less than in your smartphone. 446 00:21:55,731 --> 00:21:58,280 - 1972 was when you had the technology freeze. 447 00:21:58,281 --> 00:22:00,109 Remember we launched in 77. 448 00:22:00,110 --> 00:22:02,450 So you freeze technology several years earlier, 449 00:22:02,451 --> 00:22:05,198 and at the time the biggest computers in the world 450 00:22:05,199 --> 00:22:07,038 were comparable to the kinds of things 451 00:22:07,039 --> 00:22:08,785 we have in our pockets today. 452 00:22:08,786 --> 00:22:11,005 And I'm not talking about a cell phone. 453 00:22:11,006 --> 00:22:13,790 I'm actually talking about a key fob. 454 00:22:13,791 --> 00:22:15,418 - What's wrong with 70s technology? 455 00:22:15,419 --> 00:22:20,129 I mean, you're looking at me, I'm a 30s technology, right? 456 00:22:20,130 --> 00:22:21,676 I don't apologise for the limitations 457 00:22:21,677 --> 00:22:23,972 that we were working with at the time. 458 00:22:23,973 --> 00:22:28,888 We milked the technology for what we could get from it. 459 00:22:28,889 --> 00:22:31,307 - Voyager is about 800 kilogrammes. 460 00:22:31,308 --> 00:22:34,269 It's main antenna is 12 feet in diameter, 461 00:22:34,270 --> 00:22:36,396 which was the largest we could launch. 462 00:22:36,397 --> 00:22:37,364 - There's this body, 463 00:22:37,365 --> 00:22:40,608 this 10 sided can called the bus, 464 00:22:40,609 --> 00:22:43,488 and that's got all the electronics and the computers. 465 00:22:43,489 --> 00:22:45,032 And that's got these arms and 466 00:22:45,033 --> 00:22:46,744 these appendages that stick out. 467 00:22:46,745 --> 00:22:49,205 It has these feet that connected it to the rocket 468 00:22:49,206 --> 00:22:50,872 and then a really long arm 469 00:22:50,873 --> 00:22:53,166 with a magnetic field sensor on it over here 470 00:22:53,167 --> 00:22:56,210 and another arm over there with this plutonium power supply 471 00:22:56,211 --> 00:22:57,375 to give it its electricity. 472 00:22:57,376 --> 00:22:58,719 You can't keep that too close to the spacecraft 473 00:22:58,720 --> 00:23:00,712 because it will radiate the spacecraft. 474 00:23:00,713 --> 00:23:02,465 And another arm with this device 475 00:23:02,466 --> 00:23:04,510 that had the cameras and other instruments on it 476 00:23:04,511 --> 00:23:06,761 that could point around, kind of like the eyes, 477 00:23:06,762 --> 00:23:10,221 adn the big antenna was the ears. 478 00:23:10,222 --> 00:23:12,061 When everything is fully extended 479 00:23:12,062 --> 00:23:13,855 to its greatest dimensions, 480 00:23:13,856 --> 00:23:18,187 it's comparable in size to sort of a small school bus. 481 00:23:18,188 --> 00:23:20,523 It really is graceful, 482 00:23:20,524 --> 00:23:23,526 despite the kind of gangly appearance. 483 00:23:23,527 --> 00:23:26,487 A strange-looking being for our planet, 484 00:23:26,488 --> 00:23:28,615 but perfectly happy in space. 485 00:23:56,477 --> 00:23:59,649 - I became the producer of only one record in my career, 486 00:23:59,650 --> 00:24:01,737 and only two copies of it were made, 487 00:24:01,738 --> 00:24:03,653 and they were both hurled off the earth, 488 00:24:03,654 --> 00:24:05,745 so I don't know if that's a credential or not. 489 00:24:07,071 --> 00:24:09,035 The launch window for Voyager was set. 490 00:24:09,036 --> 00:24:11,953 It had to do with an alignment of the outer planets. 491 00:24:11,954 --> 00:24:13,669 You have to launch in that window. 492 00:24:13,670 --> 00:24:18,247 And they sure as hell weren't going to wait for the record. 493 00:24:18,248 --> 00:24:20,208 - We had six weeks to do it. 494 00:24:20,209 --> 00:24:21,548 And when I talk about the record 495 00:24:21,549 --> 00:24:24,253 I think that's what always draws the biggest gasp. 496 00:24:24,254 --> 00:24:25,505 That you had to figure out a way 497 00:24:25,506 --> 00:24:27,095 to explain the world to aliens, 498 00:24:27,096 --> 00:24:29,310 and by the way it has to be finished in six weeks. 499 00:24:34,181 --> 00:24:36,853 - We had two goals in making the Voyager record, 500 00:24:36,854 --> 00:24:37,976 in terms of the music. 501 00:24:37,977 --> 00:24:41,270 The first was we wanted the music to represent 502 00:24:41,271 --> 00:24:43,442 many different cultures around the world 503 00:24:43,443 --> 00:24:45,659 and not just the culture of the society 504 00:24:45,660 --> 00:24:48,736 that had built and launched the spacecraft. 505 00:24:52,574 --> 00:24:54,409 The other criterion was we 506 00:24:54,410 --> 00:24:57,036 wanted it to be a good record. 507 00:24:57,037 --> 00:24:59,664 - It's a very idiosyncratic message. 508 00:24:59,665 --> 00:25:01,963 It doesn't seem like something made by a committee. 509 00:25:01,964 --> 00:25:03,668 It's too quirky. 510 00:25:04,590 --> 00:25:06,179 - Nowadays you work a lot on the internet 511 00:25:06,180 --> 00:25:08,214 than those days, it was more, 512 00:25:08,215 --> 00:25:10,058 sitting in the dark listening to pieces of music, 513 00:25:10,059 --> 00:25:11,592 making notes. 514 00:25:13,137 --> 00:25:14,434 It takes a long time to go through 515 00:25:14,435 --> 00:25:17,434 a stack of records that's that high. 516 00:25:20,644 --> 00:25:22,233 If you listen to the Voyager record, 517 00:25:22,234 --> 00:25:23,521 it would be remarkable if you 518 00:25:23,522 --> 00:25:24,774 didn't hear some pieces of music 519 00:25:24,775 --> 00:25:26,193 that were quite unlike anything 520 00:25:26,194 --> 00:25:27,530 you had heard before. 521 00:25:27,531 --> 00:25:29,027 The Japanese shakuhachi piece 522 00:25:29,028 --> 00:25:32,238 or the 16 year-old pygmy girl singing 523 00:25:32,239 --> 00:25:33,707 what's called an initiation song, 524 00:25:33,708 --> 00:25:35,283 a kind of puberty song, 525 00:25:35,284 --> 00:25:37,660 In the Ituri forest of Africa 526 00:25:37,661 --> 00:25:40,289 is just unbelievably beautiful. 527 00:25:41,540 --> 00:25:45,261 The Javanese gamelan piece is just beautiful. 528 00:25:46,128 --> 00:25:48,381 The Chinese ch'in piece was the sort of thing 529 00:25:48,382 --> 00:25:50,599 that will never leave you. 530 00:25:53,093 --> 00:25:56,688 It was a terrific mind expanding adventure. 531 00:25:58,348 --> 00:26:00,271 There was a certain amount of hunting up 532 00:26:00,272 --> 00:26:03,144 rare records here and there. 533 00:26:03,145 --> 00:26:05,354 I remember the back of an Indian 534 00:26:05,355 --> 00:26:07,482 appliance store in New York 535 00:26:07,483 --> 00:26:09,484 where they had some Indian records, 536 00:26:09,485 --> 00:26:11,575 and there was one copy of a raga 537 00:26:11,576 --> 00:26:14,119 that we ended up putting on the record. 538 00:26:17,326 --> 00:26:19,044 - Always the criterion was that we were 539 00:26:19,045 --> 00:26:21,662 trying to describe our culture. 540 00:26:21,663 --> 00:26:23,961 So it would include folk music, and primitive music 541 00:26:23,962 --> 00:26:28,252 and Bach and Beethoven, and jazz, and all of that. 542 00:26:28,253 --> 00:26:29,800 And something we wanted very much 543 00:26:29,801 --> 00:26:31,923 was the music of the Beatles. 544 00:26:31,924 --> 00:26:34,258 And they said “No way." 545 00:26:34,259 --> 00:26:36,728 And we said “Well this is all going in outer space, 546 00:26:36,729 --> 00:26:39,138 "it will never be heard on earth. 547 00:26:39,139 --> 00:26:40,812 "No we don't do it.“ 548 00:26:42,851 --> 00:26:44,649 They don't licence for outer space. 549 00:26:47,815 --> 00:26:49,613 - I would have loved to have had a Bob Dylan piece 550 00:26:49,614 --> 00:26:51,526 but really there's only room 551 00:26:51,527 --> 00:26:55,404 for at most one contemporary rock piece. 552 00:26:56,698 --> 00:26:57,698 But you know you're up against 553 00:26:57,699 --> 00:26:59,075 Chuck Berry's Johnny B. Geode, 554 00:26:59,076 --> 00:27:00,043 which Bob Dylan himself would 555 00:27:00,044 --> 00:27:02,203 admit is an awfully good single. 556 00:27:02,204 --> 00:27:04,457 - It may be just four simple words 557 00:27:04,458 --> 00:27:06,502 but it is the first positive proof 558 00:27:06,503 --> 00:27:09,344 that other intelligent beings inhabit the universe. 559 00:27:09,345 --> 00:27:11,546 - What are the four words Cocuwa? 560 00:27:11,547 --> 00:27:13,798 - Send more Chuck Berry. 561 00:27:15,634 --> 00:27:18,136 - The world is full of fantastic music, 562 00:27:18,137 --> 00:27:19,102 and it goes without saying 563 00:27:19,103 --> 00:27:20,268 there's a lot more great music 564 00:27:20,269 --> 00:27:21,857 that's not on the Voyager record 565 00:27:21,858 --> 00:27:24,016 than there is on it. 566 00:27:24,017 --> 00:27:25,268 Which is a good thing, too, 567 00:27:25,269 --> 00:27:27,190 I mean, if you imagine living on a planet 568 00:27:27,191 --> 00:27:29,939 that was so pathetic that it only had 90 minutes 569 00:27:29,940 --> 00:27:31,899 of decent music. 570 00:27:31,900 --> 00:27:33,901 - Flight control to launch enable. 571 00:27:33,902 --> 00:27:34,822 - Roger. 572 00:27:34,823 --> 00:27:36,821 - A countdown will begin in 10 minutes 573 00:27:36,822 --> 00:27:38,281 before midnight tonight. 574 00:27:38,282 --> 00:27:39,534 - A journey about to begin 575 00:27:39,535 --> 00:27:41,331 which will take the technology of earth 576 00:27:41,332 --> 00:27:43,119 out of our solar system. 577 00:27:43,120 --> 00:27:45,293 - When it was launched, it was of course all folded up, 578 00:27:45,294 --> 00:27:46,916 it was like origami. 579 00:27:48,500 --> 00:27:50,835 - Here was this almost 580 00:27:50,836 --> 00:27:52,930 unexpected encapsulation. 581 00:27:54,715 --> 00:27:56,132 I mean, we knew that we were 582 00:27:56,133 --> 00:27:57,133 going to be encapsulated, 583 00:27:57,134 --> 00:27:58,807 but the emotional effect on that 584 00:27:58,808 --> 00:28:00,511 was kind of surprising. 585 00:28:00,512 --> 00:28:04,432 I noticed that in just looking around me. 586 00:28:04,433 --> 00:28:08,144 I realised that this was the last time any of us 587 00:28:08,145 --> 00:28:11,740 were going to see the spacecraft with eyes. 588 00:28:17,988 --> 00:28:20,832 That's a fairly moving experience. 589 00:28:23,785 --> 00:28:24,957 - Environmental control, ready? 590 00:28:24,958 --> 00:28:26,045 - Roger. 591 00:28:26,046 --> 00:28:29,415 - We actually launched Voyager Two first. 592 00:28:29,416 --> 00:28:31,418 And this gave the media, 593 00:28:32,961 --> 00:28:34,378 drove them nuts. 594 00:28:34,379 --> 00:28:36,464 We launched Voyager One later, 595 00:28:36,465 --> 00:28:39,093 but it was launched on a faster trajectory. 596 00:28:39,094 --> 00:28:43,179 So it overtook Voyager Two in December of 1977. 597 00:28:43,180 --> 00:28:44,807 From that point on, Voyager One 598 00:28:44,808 --> 00:28:47,353 always got to the planet before Voyager Two, 599 00:28:47,354 --> 00:28:49,941 and the press was happy, they understood it. 600 00:28:49,942 --> 00:28:51,938 - Most of the press release drawings 601 00:28:51,939 --> 00:28:53,940 show the other side of the spacecraft 602 00:28:53,941 --> 00:28:55,987 so you can't see the Voyager record. 603 00:28:55,988 --> 00:28:57,735 But when the reporters came to the launch, 604 00:28:57,736 --> 00:29:00,615 they all wanted to know more about the record. 605 00:29:00,616 --> 00:29:03,411 There was always a lot of ambiguity in NASA about this. 606 00:29:03,412 --> 00:29:05,877 There's no question that the Voyager record is useless 607 00:29:05,878 --> 00:29:07,912 from a scientific standpoint, 608 00:29:07,913 --> 00:29:11,133 and the officials reluctantly arranged a press conference. 609 00:29:15,587 --> 00:29:17,510 The press conference was a joke really. 610 00:29:17,511 --> 00:29:19,882 It was held in a hotel room 611 00:29:19,883 --> 00:29:21,259 separated by one of those 612 00:29:21,260 --> 00:29:23,556 accordion folding barriers that you pull 613 00:29:23,557 --> 00:29:26,600 across to make one room into two smaller rooms. 614 00:29:26,601 --> 00:29:28,942 From what was literally, as memory serves me, 615 00:29:28,943 --> 00:29:31,686 a Polish wedding reception. 616 00:29:31,687 --> 00:29:32,984 We did the whole press conference 617 00:29:32,985 --> 00:29:35,064 with the oompah sound of 618 00:29:35,065 --> 00:29:37,233 a wedding reception next door. 619 00:29:37,234 --> 00:29:38,827 But I think the public seemed to get it. 620 00:29:43,156 --> 00:29:44,328 - We have just had a report 621 00:29:44,329 --> 00:29:47,785 from John Casani, the Voyager Project Manager 622 00:29:47,786 --> 00:29:51,256 that we'll be able to countdown at 10:25. 623 00:29:52,624 --> 00:29:55,628 - They were launched on a Titan launch vehicle. 624 00:29:55,629 --> 00:29:57,755 Which were intercontinental ballistic missiles 625 00:29:57,756 --> 00:29:58,921 for a long time. 626 00:29:58,922 --> 00:30:01,387 And some of them as they were decommissioned 627 00:30:01,388 --> 00:30:03,761 were turned into rockets to launch spacecraft 628 00:30:03,762 --> 00:30:05,553 out to the planets. 629 00:30:05,554 --> 00:30:07,022 - Five, four, 630 00:30:07,023 --> 00:30:08,311 three, two, one. 631 00:30:10,892 --> 00:30:14,061 We have ignition, and we have liftoff. 632 00:30:14,062 --> 00:30:16,355 - You see those solids ignite 633 00:30:16,356 --> 00:30:17,699 and you're really not prepared 634 00:30:17,700 --> 00:30:19,650 for what's about to occur. 635 00:30:24,531 --> 00:30:26,954 The sound waves then catch up 636 00:30:28,452 --> 00:30:29,544 and then this 637 00:30:31,038 --> 00:30:35,416 forceful shaking, the body is actually moved 638 00:30:35,417 --> 00:30:37,920 in resonance with this energy. 639 00:30:38,795 --> 00:30:40,796 Shaking it, right. 640 00:30:42,883 --> 00:30:45,509 - We jumped up and down. 641 00:30:45,510 --> 00:30:46,761 Big hugs you know. 642 00:30:46,762 --> 00:30:49,805 We're so happy to have gotten away with it. 643 00:30:49,806 --> 00:30:50,773 And the rocket worked. 644 00:30:50,774 --> 00:30:53,059 You never know about that either. 645 00:30:53,060 --> 00:30:54,232 - We were sitting in bleachers 646 00:30:54,233 --> 00:30:57,106 and they keep you pretty far from the launch vehicle 647 00:30:57,107 --> 00:30:58,525 because they can explode, and 648 00:30:58,526 --> 00:31:00,316 it's basically, it's a big bomb. 649 00:31:00,317 --> 00:31:02,285 - So there was a little bit of holding your breath and 650 00:31:02,286 --> 00:31:03,903 wanting to make sure you see it, 651 00:31:03,904 --> 00:31:06,530 get that first little motion 652 00:31:06,531 --> 00:31:09,408 off the pad starting into space. 653 00:31:09,409 --> 00:31:11,369 - We saw that going off into space, 654 00:31:11,370 --> 00:31:12,667 we were all thinking this thought. 655 00:31:12,668 --> 00:31:13,996 There it goes 656 00:31:13,997 --> 00:31:16,045 and it's gonna be out there to represent us 657 00:31:16,046 --> 00:31:18,709 for the next five billion years. 658 00:31:18,710 --> 00:31:20,963 - I was a seven year old child watching it go 659 00:31:20,964 --> 00:31:23,339 and thinking like “Oh I had some small thing 660 00:31:23,340 --> 00:31:24,507 "to do on that." 661 00:31:24,508 --> 00:31:26,260 Like there's some part of me on that. 662 00:31:26,261 --> 00:31:28,177 But no real significance. 663 00:31:28,178 --> 00:31:30,852 But it was like, yeah okay, bye. 664 00:31:37,687 --> 00:31:40,190 - There were outbursts of joy. 665 00:31:41,066 --> 00:31:42,693 We were on our way. 666 00:31:44,611 --> 00:31:45,611 - And then we launched it 667 00:31:45,612 --> 00:31:48,365 and then other things went crazy. 668 00:31:50,367 --> 00:31:51,960 The spacecraft began to do things 669 00:31:51,961 --> 00:31:55,454 that we had no expectation that it would have done. 670 00:31:55,455 --> 00:31:57,248 - Us poor people on Earth, 671 00:31:57,249 --> 00:31:59,917 we're like "What is it doing?" 672 00:31:59,918 --> 00:32:01,841 - And as the launch vehicle leaves the launchpad, 673 00:32:01,842 --> 00:32:04,258 it has to roll through a certain angle 674 00:32:04,259 --> 00:32:07,096 to get to the right direction for departure. 675 00:32:07,097 --> 00:32:09,764 And the rate that it rolls at is a much higher rate 676 00:32:09,765 --> 00:32:12,977 than the spacecraft would ever normally experience flying. 677 00:32:12,978 --> 00:32:14,771 And so the gyro hits the stops. 678 00:32:14,772 --> 00:32:16,142 It saturates. 679 00:32:16,143 --> 00:32:17,732 - Voyager was not in control of itself. 680 00:32:17,733 --> 00:32:19,478 It's just riding this big rocket, 681 00:32:19,479 --> 00:32:21,230 and that was shaking it in such a way 682 00:32:21,231 --> 00:32:23,357 that it thought it was failing, 683 00:32:23,358 --> 00:32:25,573 and so it started switching off various boxes, 684 00:32:25,574 --> 00:32:26,777 changing to the back-up this, 685 00:32:26,778 --> 00:32:27,778 to the back-up that. 686 00:32:27,779 --> 00:32:30,326 Trying to figure out why all this stuff was happening. 687 00:32:30,327 --> 00:32:32,413 - For a couple of days it was a real nail-biter. 688 00:32:32,414 --> 00:32:33,748 People were asking us, 689 00:32:33,749 --> 00:32:34,994 "Have you lost the spacecraft" 690 00:32:34,995 --> 00:32:36,996 and we would say "We don't know for sure," 691 00:32:36,997 --> 00:32:39,582 because we didn't know for sure. 692 00:32:39,583 --> 00:32:42,793 - And the headline read “Mutiny in Space... 693 00:32:42,794 --> 00:32:44,715 The Voyager spacecraft had decided 694 00:32:44,716 --> 00:32:47,053 it just didn't want to follow the instructions 695 00:32:47,054 --> 00:32:49,013 that its human controllers were giving it 696 00:32:49,014 --> 00:32:51,556 and it was going to do what it wanted to do. 697 00:32:51,557 --> 00:32:54,477 - Fortunately, the person who had written that code 698 00:32:54,478 --> 00:32:56,765 was able to say "This is okay. 699 00:32:56,766 --> 00:32:58,437 "It's doing this, it tried that, 700 00:32:58,438 --> 00:32:59,812 “it's doing this, it tried that," 701 00:32:59,813 --> 00:33:02,480 and calm everyone else down. 702 00:33:04,941 --> 00:33:06,614 - All the time it was doing that crazy stuff 703 00:33:06,615 --> 00:33:08,819 it was doing exactly what we had 704 00:33:08,820 --> 00:33:10,404 designed it to do along. 705 00:33:11,406 --> 00:33:13,407 - The limits were set simply too tight. 706 00:33:13,408 --> 00:33:15,242 It needed to be able 707 00:33:15,243 --> 00:33:18,204 to wiggle more and vibrate more. 708 00:33:18,205 --> 00:33:21,300 And the telemetry length wasn't gonna 709 00:33:22,250 --> 00:33:24,793 be a solid as people expected. 710 00:33:24,794 --> 00:33:26,170 So all of those things 711 00:33:26,171 --> 00:33:28,923 that had caused issues with Voyager Two 712 00:33:28,924 --> 00:33:31,677 then were solved for Voyager One. 713 00:33:32,677 --> 00:33:33,802 - Titan Centaur 6 714 00:33:33,803 --> 00:33:35,179 has lifted off at 8:56 from here 715 00:33:35,180 --> 00:33:36,976 at the Cape Canaveral Air Force Station. 716 00:33:36,977 --> 00:33:38,894 - When Voyager One lifted off, 717 00:33:38,895 --> 00:33:40,606 we're thinking everything's okay. 718 00:33:40,607 --> 00:33:42,273 And then we begin to hear this, 719 00:33:42,274 --> 00:33:44,318 we call it chatter over the launch vehicle net 720 00:33:44,319 --> 00:33:46,440 that something wasn't right. 721 00:33:46,441 --> 00:33:47,818 - I looked over at him and he looked like 722 00:33:47,819 --> 00:33:48,862 he was a little worried. 723 00:33:48,863 --> 00:33:50,574 And I said "What's the matter, Charley?" 724 00:33:50,575 --> 00:33:51,822 And he says "I don't know, 725 00:33:51,823 --> 00:33:55,074 "I don't think we're going to make it, you know." 726 00:33:55,075 --> 00:33:56,951 There was a leak in the propellant line, 727 00:33:56,952 --> 00:33:58,829 and we were losing propellant overboard. 728 00:33:58,830 --> 00:34:00,454 So while it was burning, 729 00:34:00,455 --> 00:34:02,456 propellant was escaping from the launch vehicle. 730 00:34:02,457 --> 00:34:04,175 And that's why second stage never got 731 00:34:04,176 --> 00:34:05,918 to deliver its full thrust 732 00:34:05,919 --> 00:34:07,590 because it ran out of fuel. 733 00:34:07,591 --> 00:34:09,885 - And so the upper which was a Centaur, 734 00:34:09,886 --> 00:34:12,383 liquid, hydrogen, and oxygen stage 735 00:34:12,384 --> 00:34:14,009 had to make up for that. 736 00:34:14,010 --> 00:34:15,224 - And the Centaur is the stage 737 00:34:15,225 --> 00:34:16,559 that's doing the guidance. 738 00:34:16,560 --> 00:34:18,774 So the Centaur knows that it's not reaching 739 00:34:18,775 --> 00:34:20,266 the required velocity. 740 00:34:20,267 --> 00:34:23,310 And when it separates from the second stage 741 00:34:23,311 --> 00:34:25,109 it knows it has to burn longer 742 00:34:25,110 --> 00:34:27,147 to add more velocity. 743 00:34:27,148 --> 00:34:30,150 - The Centaur, to achieve parking orbit, 744 00:34:30,151 --> 00:34:33,904 had to use 1,200 pounds of extra propellant. 745 00:34:33,905 --> 00:34:35,157 Now we're all thinking, 746 00:34:35,158 --> 00:34:37,250 is it going to have enough left in the tanks 747 00:34:37,251 --> 00:34:39,201 to make a normal injection? 748 00:34:39,202 --> 00:34:41,330 Or is it going to run out of fuel? 749 00:34:43,790 --> 00:34:47,376 Fortunately, it had three and a half seconds 750 00:34:47,377 --> 00:34:50,927 of thrusting left before it had run to fuel depletion. 751 00:34:50,928 --> 00:34:52,923 Three and a half seconds, 752 00:34:52,924 --> 00:34:56,010 so Voyager One just barely made it. 753 00:34:56,011 --> 00:34:57,228 - It wouldn't have gotten enough velocity 754 00:34:57,229 --> 00:34:58,762 to get to Jupiter, you know. 755 00:34:58,763 --> 00:35:00,481 So instead of getting to Jupiter, you know, 756 00:35:00,482 --> 00:35:02,062 we'd have gotten almost to Jupiter 757 00:35:02,063 --> 00:35:03,976 and then we'd come back toward the Sun, 758 00:35:03,977 --> 00:35:05,102 which would not have been good. 759 00:35:07,272 --> 00:35:11,859 ♫ I watch the distant ♫ ♫ lights go down a long way ♫ 760 00:35:11,860 --> 00:35:16,530 ♫ Disappear into the evening sky ♫ 761 00:35:16,531 --> 00:35:18,574 ♫ Oh you know I'm with you ♫ 762 00:35:18,575 --> 00:35:21,577 ♫ On your journey ♫ 763 00:35:21,578 --> 00:35:24,330 ♫ Never could say goodbye ♫ 764 00:35:24,331 --> 00:35:26,004 -

It's what realising that a human life ago, 785 00:36:35,320 --> 00:36:37,491 less than 100 years ago, 87 years ago, 786 00:36:37,492 --> 00:36:40,489 the universe consisted of one galaxy, 787 00:36:40,490 --> 00:36:41,990 our Milky Way Galaxy. 788 00:36:41,991 --> 00:36:45,786 In a static eternal universe with eternal empty space. 789 00:36:45,787 --> 00:36:48,006 We didn't know about the other hundred billion galaxies 790 00:36:48,007 --> 00:36:50,290 a single human lifetime ago. 791 00:36:50,291 --> 00:36:52,089 And we didn't know the universe was expanding 792 00:36:52,090 --> 00:36:55,921 and it was born in a big bang 13.7 billion years ago. 793 00:36:55,922 --> 00:36:57,469 But even stranger things like 794 00:36:57,470 --> 00:36:58,924 the things I work on. 795 00:36:58,925 --> 00:37:01,303 The fact that most of the mass of our galaxies invisible. 796 00:37:01,304 --> 00:37:03,053 It's made of stuff other than you or me. 797 00:37:03,054 --> 00:37:05,055 We think it's made of some new elementary particle 798 00:37:05,056 --> 00:37:06,890 that is actually going right through you 799 00:37:06,891 --> 00:37:08,689 and me right now and right through the earth 800 00:37:08,690 --> 00:37:10,187 without even noticing it was there. 801 00:37:10,188 --> 00:37:11,904 Even stranger than that is the fact 802 00:37:11,905 --> 00:37:14,565 that empty space weighs something. 803 00:37:14,566 --> 00:37:16,694 You get rid of all the particles and the radiation, 804 00:37:16,695 --> 00:37:19,194 you have nothing there and it weighs something. 805 00:37:19,195 --> 00:37:21,196 And moreover, it's the dominant energy in the universe 806 00:37:21,197 --> 00:37:23,699 and we don't have the slightest idea why it's there. 807 00:37:39,632 --> 00:37:41,634 - You can never imagine. 808 00:37:42,510 --> 00:37:44,353 You can try, but you can never really imagine 809 00:37:44,354 --> 00:37:47,264 what mother nature will actually 810 00:37:47,265 --> 00:37:49,099 have in store 811 00:37:49,100 --> 00:37:50,642 when you get there. 812 00:37:57,650 --> 00:38:00,244 It seems like time really flew. 813 00:38:02,864 --> 00:38:06,118 - I don't think we really fully understood 814 00:38:06,119 --> 00:38:07,868 before the first Jupiter encounter, 815 00:38:07,869 --> 00:38:09,667 just how intense it was going to be. 816 00:38:09,668 --> 00:38:10,834 No, we didn't. 817 00:38:12,832 --> 00:38:13,832 We found out. 818 00:38:16,961 --> 00:38:18,462 - It's an interesting phenomena that you 819 00:38:18,463 --> 00:38:21,298 start working on a mission in 1972, 820 00:38:21,299 --> 00:38:23,467 you launch in 1977. 821 00:38:23,468 --> 00:38:25,928 All of that, there's no science. 822 00:38:25,929 --> 00:38:27,596 It's all getting ready. 823 00:38:27,597 --> 00:38:30,682 And then March 79, the flood. 824 00:38:45,740 --> 00:38:50,118 - The encounters, they creep up on you. 825 00:38:50,119 --> 00:38:52,463 We started what we call the observatory phase 826 00:38:52,464 --> 00:38:54,581 with our long telephoto camera, 827 00:38:54,582 --> 00:38:57,334 and that's when we started seeing day by day 828 00:38:57,335 --> 00:39:00,087 larger and larger Jupiter. 829 00:39:00,088 --> 00:39:01,964 - When we were approaching, every picture 830 00:39:01,965 --> 00:39:05,425 was the greatest picture ever taken of Jupiter. 831 00:39:05,426 --> 00:39:08,178 - In the beginning, it would be just a little dot 832 00:39:08,179 --> 00:39:10,307 getting bigger on the screen every day. 833 00:39:10,308 --> 00:39:13,225 And as we would get closer and closer, 834 00:39:13,226 --> 00:39:15,945 the images became more dramatic. 835 00:39:16,938 --> 00:39:19,111 - Incredibly strange, and beautiful, 836 00:39:19,112 --> 00:39:23,283 and now by Voyager revealed in all of it's splendour. 837 00:39:25,947 --> 00:39:27,665 - We were trying to get as much 838 00:39:27,666 --> 00:39:29,199 detail as possible. 839 00:39:29,200 --> 00:39:32,955 So a narrow angle camera was 1500 millimetres 840 00:39:33,788 --> 00:39:37,634 and the wide angle camera was 200 millimetres. 841 00:39:38,668 --> 00:39:40,088 - Would someone care to speculate 842 00:39:40,089 --> 00:39:42,507 what you would say to Galileo Galilei 843 00:39:42,508 --> 00:39:44,631 if he walked into the room today? 844 00:39:45,475 --> 00:39:47,968 - How are you able to live so long? 845 00:39:54,183 --> 00:39:55,517 - I think Galileo. 846 00:39:55,518 --> 00:39:57,441 - Jupiter is more than 10 times the diameter of earth. 847 00:39:57,442 --> 00:39:58,687 It's huge! 848 00:39:58,688 --> 00:39:59,940 And it's mainly hydrogen and helium. 849 00:39:59,941 --> 00:40:01,815 There are no solid surface on these planets. 850 00:40:01,816 --> 00:40:05,527 These planets are liquid gas and liquid deep inside. 851 00:40:05,528 --> 00:40:08,122 - The gas is compressed the farther down you go 852 00:40:08,123 --> 00:40:10,458 and it gets very hot indeed. 853 00:40:12,285 --> 00:40:14,620 You would melt, vaporise in fact, 854 00:40:14,621 --> 00:40:17,539 if you tried to fly through Jupiter. 855 00:40:17,540 --> 00:40:19,416 - Let me first modify your statement. 856 00:40:19,417 --> 00:40:20,509 Not that it was wrong. 857 00:40:20,510 --> 00:40:22,502 - The atmospheric scientists 858 00:40:22,503 --> 00:40:25,177 got long-range views because we weren't looking 859 00:40:25,178 --> 00:40:29,176 at tiny moons, we were looking at the big planet, 860 00:40:29,177 --> 00:40:31,053 and so we could see things going on 861 00:40:31,054 --> 00:40:34,556 before the other groups could see things. 862 00:40:34,557 --> 00:40:38,437 And we were always the first to start shouting. 863 00:40:39,479 --> 00:40:43,815 - Even to this day we don't fly colour detectors. 864 00:40:43,816 --> 00:40:45,984 You get a much higher-resolution 865 00:40:45,985 --> 00:40:47,736 image in black and white. 866 00:40:47,737 --> 00:40:49,529 And so when we want to make colour, 867 00:40:49,530 --> 00:40:50,998 we take them through different filters 868 00:40:50,999 --> 00:40:52,741 and then on the ground you put it together 869 00:40:52,742 --> 00:40:55,619 and make a colour image out of it. 870 00:40:55,620 --> 00:40:57,873 - That acceleration as you're approaching encounters 871 00:40:57,874 --> 00:41:00,290 is really something that becomes very, very exciting. 872 00:41:00,291 --> 00:41:02,337 We called it drinking out of a fire hose, you know, 873 00:41:02,338 --> 00:41:03,587 you're trying to take a little sip, 874 00:41:03,588 --> 00:41:06,055 and this torrent of data is coming out. 875 00:41:08,716 --> 00:41:11,218 - You go to Jupiter and you have a storm that's been 876 00:41:11,219 --> 00:41:13,220 around for more than 300 years, 877 00:41:13,221 --> 00:41:14,894 that's the Great Red Spot. 878 00:41:14,895 --> 00:41:18,141 You could fit two or three Earths inside it. 879 00:41:18,142 --> 00:41:19,860 So here's the Great Red Spot and here's an earth 880 00:41:19,861 --> 00:41:21,561 and here's an earth. 881 00:41:21,562 --> 00:41:23,814 It's always going around. 882 00:41:23,815 --> 00:41:27,401 And I sort of assumed that the flow around 883 00:41:27,402 --> 00:41:29,486 these giant things would be 884 00:41:29,487 --> 00:41:31,655 smooth like honey. 885 00:41:31,656 --> 00:41:35,200 But, when Voyager started getting close-up images, 886 00:41:35,201 --> 00:41:37,619 we realised that it was very active. 887 00:41:37,620 --> 00:41:39,621 And that deepened the mystery 888 00:41:39,622 --> 00:41:42,541 of how these big storms could even exist 889 00:41:42,542 --> 00:41:43,634 with all this 890 00:41:44,961 --> 00:41:46,670 turbulence going on. 891 00:41:46,671 --> 00:41:50,549 - It was swallowing up clouds and spitting out others. 892 00:41:50,550 --> 00:41:52,843 We knew that it was a vortex, 893 00:41:52,844 --> 00:41:55,063 but to see it in action... 894 00:41:58,433 --> 00:41:59,433 - Every day you're wondering 895 00:41:59,434 --> 00:42:01,061 "Did we build the spacecraft well enough? 896 00:42:01,062 --> 00:42:03,404 "Did we anticipate all the possible things 897 00:42:03,405 --> 00:42:05,239 "that could go wrong?" 898 00:42:07,025 --> 00:42:09,198 - Pioneer 10 had to measure the radiation environment 899 00:42:09,199 --> 00:42:11,361 which was much greater than our 900 00:42:11,362 --> 00:42:13,739 earth based interpretation suggested. 901 00:42:19,704 --> 00:42:22,125 - You're approaching this monster essentially. 902 00:42:22,126 --> 00:42:23,712 This monster magnetic field, 903 00:42:23,713 --> 00:42:26,630 this monster radiation environment on purpose, 904 00:42:26,631 --> 00:42:28,170 because you need to get close 905 00:42:28,171 --> 00:42:29,639 because you want to see all the little moons, 906 00:42:29,640 --> 00:42:31,381 and the clouds, and the storms, 907 00:42:31,382 --> 00:42:33,759 and you want to slingshot on to Saturn. 908 00:42:33,760 --> 00:42:37,054 But you just don't know if you're going to survive. 909 00:42:37,055 --> 00:42:38,272 Thing gets fried, you lose the mission. 910 00:42:38,273 --> 00:42:40,107 Still out there physically intact probably, 911 00:42:40,108 --> 00:42:44,019 but unable to communicate with it, the mission's over. 912 00:42:44,020 --> 00:42:47,606 - Two months before shipping to the Cape for launch, 913 00:42:47,607 --> 00:42:49,775 the scientists were predicting 914 00:42:49,776 --> 00:42:52,861 that the magnetic fields around Jupiter 915 00:42:52,862 --> 00:42:54,455 were intense enough that they 916 00:42:54,456 --> 00:42:57,365 would accelerate particles. 917 00:42:57,366 --> 00:43:00,869 Whoa, we were hearing initially 40,000 volts, 918 00:43:00,870 --> 00:43:04,081 that would be the end of our spacecraft. 919 00:43:04,082 --> 00:43:07,125 Cabling on these appendages were conductors 920 00:43:07,126 --> 00:43:09,220 that would take these destroying pulses 921 00:43:09,221 --> 00:43:12,964 and just feed them right into our systems and kill us, 922 00:43:12,965 --> 00:43:15,809 so we needed to ground everything. 923 00:43:16,677 --> 00:43:17,599 We didn't have time 924 00:43:17,600 --> 00:43:20,305 to go through the normal design reviews, 925 00:43:20,306 --> 00:43:22,099 so in order to get this 926 00:43:22,100 --> 00:43:24,101 protection done quickly enough, 927 00:43:24,102 --> 00:43:26,770 an ad hoe team was formed 928 00:43:26,771 --> 00:43:29,115 and we did some things that were out of the ordinary, 929 00:43:29,116 --> 00:43:31,775 very out of the ordinary. 930 00:43:31,776 --> 00:43:33,995 I can remember asking one of the technicians 931 00:43:33,996 --> 00:43:36,705 to go out and buy aluminium foil. 932 00:43:37,573 --> 00:43:40,167 It was the only material that was available to us. 933 00:43:40,168 --> 00:43:43,537 Normally our procurement of spacecraft 934 00:43:43,538 --> 00:43:47,293 hardware supplies, materials, are a much more 935 00:43:48,960 --> 00:43:50,803 sophisticated process. 936 00:43:51,712 --> 00:43:53,635 We're all in bunny suits actually 937 00:43:53,636 --> 00:43:55,924 cutting continuous strips 938 00:43:55,925 --> 00:43:59,386 and then cleaning them with wipes and alcohol. 939 00:43:59,387 --> 00:44:01,981 And then finally wrapping these on all of 940 00:44:01,982 --> 00:44:04,099 our exterior cabling. 941 00:44:04,100 --> 00:44:08,728 But yeah, same materials in your Christmas turkey. 942 00:44:08,729 --> 00:44:11,151 I don't think we created any shortage per se. 943 00:44:11,152 --> 00:44:13,026 It may have been a local shortage 944 00:44:13,027 --> 00:44:15,699 in the local grocery store for a few days 945 00:44:15,700 --> 00:44:17,737 until they reordered right. 946 00:44:17,738 --> 00:44:19,990 Your turkey wrapping is protecting Voyager, 947 00:44:19,991 --> 00:44:23,034 and now fast forward, you know, 948 00:44:23,035 --> 00:44:26,037 did we know whether we had done enough? 949 00:44:34,463 --> 00:44:37,215 - Amazingly we hear all kinds of sounds. 950 00:44:37,216 --> 00:44:39,593 It's a very curious phenomenon. 951 00:44:39,594 --> 00:44:41,346 You don't expect the molecules up in the 952 00:44:41,347 --> 00:44:43,564 corner of a room to suddenly get together 953 00:44:43,565 --> 00:44:45,640 and start whistling at you. 954 00:44:45,641 --> 00:44:48,986 But in a plasma, in this radiation belt, 955 00:44:50,188 --> 00:44:52,230 that can happen. 956 00:44:52,231 --> 00:44:53,904 - I'm gonna call them radio sounds because 957 00:44:53,905 --> 00:44:56,240 we have to detect them with antennas. 958 00:44:56,241 --> 00:44:58,782 - If you had the right kind of antennas on your ears 959 00:44:58,783 --> 00:45:00,577 you could go out and hear what we record. 960 00:45:03,784 --> 00:45:05,202 - Whistlers. 961 00:45:05,203 --> 00:45:09,206 These things that go, like that. 962 00:45:09,207 --> 00:45:10,916 Yeah, whistlers mean lightning. 963 00:45:10,917 --> 00:45:12,544 That was the first detection of lightning 964 00:45:12,545 --> 00:45:14,836 on a planet other than Earth. 965 00:45:14,837 --> 00:45:15,882 Much more intense. 966 00:45:15,883 --> 00:45:17,881 There are lightning flashes at Jupiter 967 00:45:17,882 --> 00:45:20,226 that would go halfway from the east coast 968 00:45:20,227 --> 00:45:22,844 of the United States to the west coast. 969 00:45:22,845 --> 00:45:26,348 So it's fascinating what you hear in space. 970 00:45:30,561 --> 00:45:32,404 - When you're on a flyby mission 971 00:45:32,405 --> 00:45:35,148 there ain't no second chance. 972 00:45:35,149 --> 00:45:36,441 - We were getting pictures, 973 00:45:36,442 --> 00:45:37,864 they were getting better and better. 974 00:45:37,865 --> 00:45:39,736 And you could begin to see detail 975 00:45:39,737 --> 00:45:41,780 as these moons got bigger. 976 00:45:41,781 --> 00:45:42,906 You know the dread you have 977 00:45:42,907 --> 00:45:44,534 is that you don't want to see 978 00:45:44,535 --> 00:45:46,534 a lot of worlds that look like Earth's moon. 979 00:45:46,535 --> 00:45:48,912 Let's face it, it's dull. 980 00:45:48,913 --> 00:45:51,712 - Our mind's eye was oh yeah, we're gonna see 981 00:45:51,713 --> 00:45:54,381 battered ice balls and so forth. 982 00:45:55,419 --> 00:45:59,092 When we saw Callisto, basically it's totally hammered right? 983 00:45:59,093 --> 00:46:01,011 Saturated with impact craters. 984 00:46:01,012 --> 00:46:03,227 Ganymede shows a lot of interesting 985 00:46:03,228 --> 00:46:05,136 grooves and ridges. 986 00:46:05,137 --> 00:46:07,856 But it's pretty blasted with impact craters. 987 00:46:07,857 --> 00:46:11,068 And then as we went into the inner two. 988 00:46:12,186 --> 00:46:15,026 - You could not see craters on either one of them. 989 00:46:15,027 --> 00:46:16,442 Well this was encouraging, 990 00:46:16,443 --> 00:46:18,738 because now we think maybe this mission 991 00:46:18,739 --> 00:46:22,028 is going to find a lot of diversity. 992 00:46:22,029 --> 00:46:26,825 - Discovering this billiard ball, smooth, icy crust 993 00:46:26,826 --> 00:46:28,868 of Europa with cracks in it 994 00:46:28,869 --> 00:46:31,084 and what looked like plates of ice 995 00:46:31,085 --> 00:46:33,545 that might be moving relative to each other, 996 00:46:33,546 --> 00:46:34,793 the best explanation for that 997 00:46:34,794 --> 00:46:36,293 is that there's a thick ocean 998 00:46:36,294 --> 00:46:37,921 of liquid water, salty water 999 00:46:37,922 --> 00:46:40,093 underneath that icy crust. 1000 00:46:41,340 --> 00:46:43,717 More ocean water than on the entire Earth, 1001 00:46:43,718 --> 00:46:44,970 probably two or three times. 1002 00:46:44,971 --> 00:46:46,845 It's the largest ocean in the solar system 1003 00:46:46,846 --> 00:46:49,014 in a moon going around Jupiter. 1004 00:46:49,015 --> 00:46:51,143 - And then of course, you know, kind of the showstopper 1005 00:46:51,144 --> 00:46:54,019 for Voyager, we get to Io. 1006 00:46:54,020 --> 00:46:54,896 - Io, of course, 1007 00:46:54,897 --> 00:46:56,363 Io was the star of the show 1008 00:46:56,364 --> 00:46:58,106 and we didn't learn that 1009 00:46:58,107 --> 00:47:00,280 until after the encounter. 1010 00:47:01,736 --> 00:47:03,329 - Everyone had gone home, 1011 00:47:03,330 --> 00:47:06,740 and Linda Morabito, an engineer whose job 1012 00:47:06,741 --> 00:47:08,867 was to find out the positioning 1013 00:47:08,868 --> 00:47:10,586 and the orbit of the spacecraft, 1014 00:47:10,587 --> 00:47:13,457 noticed some bumps on images of Io. 1015 00:47:14,957 --> 00:47:16,458 - I was on the mission 1016 00:47:16,459 --> 00:47:18,668 as a mission navigator, 1017 00:47:18,669 --> 00:47:21,629 and our job involved just looking back 1018 00:47:21,630 --> 00:47:24,299 over the shoulder of the spacecraft 1019 00:47:24,300 --> 00:47:27,804 to say, "Okay, one more picture of the realm of Jupiter." 1020 00:47:27,805 --> 00:47:30,805 So it wasn't high-priority work. 1021 00:47:30,806 --> 00:47:33,850 - It was an optical navigation image, 1022 00:47:33,851 --> 00:47:37,606 and Linda saw this strange thing on the limb. 1023 00:47:38,731 --> 00:47:42,609 - An enormous object emerged, enormous. 1024 00:47:42,610 --> 00:47:45,830 And the first thing I said to myself, "What is that?!" 1025 00:47:45,831 --> 00:47:49,542 And I'm like it looks like another satellite 1026 00:47:50,785 --> 00:47:54,746 in the picture emerging from behind Io. 1027 00:47:54,747 --> 00:47:56,790 An object that size, 1028 00:47:56,791 --> 00:47:58,543 at that range, at that distance, 1029 00:47:58,544 --> 00:47:59,885 would have been seen from Earth, 1030 00:47:59,886 --> 00:48:02,379 it was sufficiently large. 1031 00:48:02,380 --> 00:48:03,922 I felt with certainty, 1032 00:48:03,923 --> 00:48:05,011 it's the only thing I knew, 1033 00:48:05,012 --> 00:48:08,637 that I was seeing something that had never been seen before. 1034 00:48:08,638 --> 00:48:11,389 This was an umbrella-shaped plume 1035 00:48:12,598 --> 00:48:14,350 rising 250 kilometres 1036 00:48:16,060 --> 00:48:18,228 above the surface of Io 1037 00:48:18,229 --> 00:48:20,522 with volcanic activity. 1038 00:48:24,402 --> 00:48:26,861 I found the very first evidence 1039 00:48:26,862 --> 00:48:29,197 of active volcanism 1040 00:48:29,198 --> 00:48:31,576 on a world beyond the Earth. 1041 00:48:35,454 --> 00:48:37,544 - It was so hard to believe that a little moon 1042 00:48:37,545 --> 00:48:39,668 could have 10 times the volcanic activity of Earth, 1043 00:48:39,669 --> 00:48:41,418 which was the only known active volcanoes 1044 00:48:41,419 --> 00:48:43,509 in the solar system were here on Earth. 1045 00:48:43,510 --> 00:48:44,676 And then there's Io. 1046 00:48:44,677 --> 00:48:47,048 Suddenly we had realised 1047 00:48:47,049 --> 00:48:49,467 this was a different journey we were on. 1048 00:48:49,468 --> 00:48:50,513 - I wanted to say one other thing. 1049 00:48:50,514 --> 00:48:51,888 We've been saying that perhaps there's some 1050 00:48:51,889 --> 00:48:53,638 funny way in which Jupiter gobbles up 1051 00:48:53,639 --> 00:48:55,140 all the things that are coming in 1052 00:48:55,141 --> 00:48:57,109 and it doesn't let Io be hit by any. 1053 00:48:57,110 --> 00:49:00,728 Well, we aimed a spacecraft and went very close. 1054 00:49:00,729 --> 00:49:02,318 Had we missed we would have made 1055 00:49:02,319 --> 00:49:03,611 the first impact crater. 1056 00:49:05,359 --> 00:49:07,361 - The flyby is basically 1057 00:49:08,404 --> 00:49:12,282 a week-long affair that's 24 hours a day. 1058 00:49:12,283 --> 00:49:13,741 It's intense. 1059 00:49:13,742 --> 00:49:15,994 - There will be a Voyager report 1060 00:49:15,995 --> 00:49:17,829 in 30 seconds. 1061 00:49:26,422 --> 00:49:28,265 - Instant science because there's gonna be 1062 00:49:28,266 --> 00:49:29,471 a press conference that night. 1063 00:49:29,472 --> 00:49:30,637 This picture comes down, 1064 00:49:30,638 --> 00:49:32,010 and you've got three hours 1065 00:49:32,011 --> 00:49:33,431 to figure out what's going on 1066 00:49:33,432 --> 00:49:35,180 and then tell the world about it. 1067 00:49:35,181 --> 00:49:37,140 Oh, no pressure there, right? 1068 00:49:38,476 --> 00:49:40,768 - The confines of being a piece of biology 1069 00:49:40,769 --> 00:49:41,689 got in the way of that. 1070 00:49:41,690 --> 00:49:42,563 I mean, you got hungry, 1071 00:49:42,564 --> 00:49:43,771 you got tired, you know, 1072 00:49:43,772 --> 00:49:44,864 you had to go to the bathroom, 1073 00:49:44,865 --> 00:49:46,653 I mean, you're going to miss something! 1074 00:49:46,654 --> 00:49:48,196 You don't want to miss anything 1075 00:49:48,197 --> 00:49:50,663 because every 48 seconds a new image would come down. 1076 00:49:55,242 --> 00:49:56,493 - No one got any sleep 1077 00:49:56,494 --> 00:49:58,087 during one of these flybys 1078 00:49:58,088 --> 00:50:00,997 when the spacecraft would go zooming past. 1079 00:50:00,998 --> 00:50:04,459 The photo labs were working day and night, 1080 00:50:04,460 --> 00:50:07,086 and people were sleeping in their cars. 1081 00:50:13,010 --> 00:50:16,930 - It was just way too exciting to sleep. 1082 00:50:47,169 --> 00:50:48,421 - This is the first picture 1083 00:50:48,422 --> 00:50:50,338 every of Jupiter's ring. 1084 00:50:56,512 --> 00:50:58,810 - Jupiter was really just wonderful. 1085 00:50:58,811 --> 00:51:01,980 It was just discovery after discovery. 1086 00:51:03,435 --> 00:51:05,311 -

The thing about the Voyager mission 1283 01:00:19,037 --> 01:00:21,450 from Jupiter to Saturn was the short 1284 01:00:21,451 --> 01:00:23,619 space between those. 1285 01:00:23,620 --> 01:00:25,496 Jupiter to Saturn went just like that. 1286 01:00:25,497 --> 01:00:26,997 It was really quick. 1287 01:00:35,132 --> 01:00:37,430 It's easy to think of Jupiter as the bully, 1288 01:00:37,431 --> 01:00:40,261 it's the alpha male of the solar system. 1289 01:00:40,262 --> 01:00:41,554 No question. 1290 01:00:41,555 --> 01:00:45,015 I think Saturn is majestic with rings 1291 01:00:45,016 --> 01:00:48,853 giving that sense of beauty and serenity. 1292 01:00:48,854 --> 01:00:52,022 And the moon's sort of subservient 1293 01:00:52,023 --> 01:00:54,196 and somewhat pushed aside. 1294 01:00:55,277 --> 01:00:56,904 - We started off with images that were 1295 01:00:56,905 --> 01:00:59,738 probably no better than what you can get from the ground. 1296 01:00:59,739 --> 01:01:01,582 And then it keeps getting better and better and better 1297 01:01:01,583 --> 01:01:03,659 as you get closer and closer. 1298 01:01:03,660 --> 01:01:07,246 What are we going to see when we get really close? 1299 01:01:07,247 --> 01:01:08,998 - Having seen Saturn in a telescope 1300 01:01:08,999 --> 01:01:11,218 with the rings just looking like these little tiny ears 1301 01:01:11,219 --> 01:01:13,752 on either side, to now seeing detail 1302 01:01:13,753 --> 01:01:15,588 and the beauty of Saturn's rings. 1303 01:01:15,589 --> 01:01:17,387 You know, looking like, almost like the grooves 1304 01:01:17,388 --> 01:01:19,133 on a phonograph record. 1305 01:01:19,134 --> 01:01:21,886 The rings of Saturn, what are they? 1306 01:01:21,887 --> 01:01:23,637 Billions of icy particles, 1307 01:01:23,638 --> 01:01:25,890 some the size of a house. 1308 01:01:25,891 --> 01:01:26,983 They're enormous, much wider 1309 01:01:26,984 --> 01:01:29,069 than many Earths strung together 1310 01:01:29,070 --> 01:01:32,188 but less than a kilometre thick. 1311 01:01:32,189 --> 01:01:34,942 - We get there and we find that it's a blizzard 1312 01:01:34,943 --> 01:01:36,989 of features throughout the rings, 1313 01:01:36,990 --> 01:01:39,653 and it got very complex. 1314 01:01:52,125 --> 01:01:54,460 We become junkies. 1315 01:01:54,461 --> 01:01:55,838 Who, this is how you become 1316 01:01:55,839 --> 01:01:58,380 a planetary flyby junkie, 1317 01:01:58,381 --> 01:01:59,596 it's because you've gone through 1318 01:01:59,597 --> 01:02:01,264 one of them and you just know it's the greatest feeling 1319 01:02:01,265 --> 01:02:04,428 and you want to keep doing it again and again. 1320 01:02:04,429 --> 01:02:05,772 - At some point, 1321 01:02:06,890 --> 01:02:08,103 perhaps a year or so from now 1322 01:02:08,104 --> 01:02:09,646 it may be possible to put all this 1323 01:02:09,647 --> 01:02:11,065 into perspective. 1324 01:02:12,145 --> 01:02:14,438 But right at the moment, 1325 01:02:14,439 --> 01:02:16,941 I cannot recall being in such a 1326 01:02:16,942 --> 01:02:21,862 state euphoria for any previous planetary encounter. 1327 01:02:21,863 --> 01:02:24,657 Including our two remarkable 1328 01:02:24,658 --> 01:02:27,368 Voyager encounters at Jupiter. 1329 01:02:57,482 --> 01:02:58,779 - The largest moon of Saturn, 1330 01:02:58,780 --> 01:03:01,153 Titan's the most extraordinary place. 1331 01:03:01,154 --> 01:03:03,821 There's a dense methane atmosphere 1332 01:03:03,822 --> 01:03:06,325 where a complex organic chemistry has been going on 1333 01:03:06,326 --> 01:03:07,917 for perhaps billions of years, 1334 01:03:07,918 --> 01:03:12,830 and we are in a moment of extraordinary discovery. 1335 01:03:12,831 --> 01:03:15,129 - We had both spacecraft programmed 1336 01:03:15,130 --> 01:03:17,584 to do identical missions at Saturn, 1337 01:03:17,585 --> 01:03:19,258 and that was the prime mission 1338 01:03:19,259 --> 01:03:21,097 and it involved Titan. 1339 01:03:22,215 --> 01:03:23,592 - There's a huge amount amount of scientific interest 1340 01:03:23,593 --> 01:03:25,217 in Titan because many people think 1341 01:03:25,218 --> 01:03:26,513 that early in our own history, 1342 01:03:26,514 --> 01:03:28,184 our own planet may have been like that 1343 01:03:28,185 --> 01:03:31,557 with very little oxygen, lots of hydrocarbons, 1344 01:03:31,558 --> 01:03:34,435 very thick, different, smoggy atmosphere 1345 01:03:34,436 --> 01:03:37,938 that was changed dramatically on our planet by life. 1346 01:03:37,939 --> 01:03:39,690 So if you want to understand the starting conditions, 1347 01:03:39,691 --> 01:03:40,908 go study Titan. 1348 01:03:41,860 --> 01:03:44,657 - If Voyager One was successful at Titan, 1349 01:03:44,658 --> 01:03:47,908 Voyager Two, which is nine months behind going to Saturn, 1350 01:03:47,909 --> 01:03:49,908 would be free to continue to 1351 01:03:49,909 --> 01:03:51,660 Uranus and to go on to Neptune. 1352 01:03:51,661 --> 01:03:55,748 But it depended upon Voyager One succeeding at Titan. 1353 01:03:55,749 --> 01:03:59,049 - Because Voyager One had to be in a certain place 1354 01:03:59,050 --> 01:04:00,794 in order to pass Titan, 1355 01:04:00,795 --> 01:04:03,342 it couldn't go on to Uranus and Neptune. 1356 01:04:03,343 --> 01:04:05,217 There was just no way to bend its trajectory 1357 01:04:05,218 --> 01:04:06,889 to go anywhere else. 1358 01:04:07,969 --> 01:04:11,764 - Voyager Two would have done exactly that same thing 1359 01:04:11,765 --> 01:04:13,932 if Voyager One had failed. 1360 01:04:13,933 --> 01:04:16,812 We would have gone like this, no more planets. 1361 01:04:16,813 --> 01:04:18,400 - That would have been really tough. 1362 01:04:18,401 --> 01:04:20,194 You gonna try for Titan again 1363 01:04:20,195 --> 01:04:24,693 and give up two other worlds, Uranus and Neptune? 1364 01:04:24,694 --> 01:04:29,615 - So there was a lot of pressure on Voyager One. 1365 01:04:29,616 --> 01:04:30,741 - Mostly what we looked at 1366 01:04:30,742 --> 01:04:33,827 was a giant ball of brown smog 1367 01:04:33,828 --> 01:04:37,753 with some sort of electric blue hazes above it. 1368 01:04:38,917 --> 01:04:40,089 - With the Voyager camera, 1369 01:04:40,090 --> 01:04:43,504 you couldn't see through the clouds and haze. 1370 01:04:49,386 --> 01:04:52,096 Now the radio signal from the spacecraft 1371 01:04:52,097 --> 01:04:54,769 passed through the atmosphere of the planet, 1372 01:04:54,770 --> 01:04:56,313 and that gave them a measure 1373 01:04:56,314 --> 01:04:58,435 of the pressure at the surface 1374 01:04:58,436 --> 01:05:00,732 and also the temperature at the surface. 1375 01:05:00,733 --> 01:05:02,323 And so we learned a lot about 1376 01:05:02,324 --> 01:05:05,442 Titan from that radio signal. 1377 01:05:05,443 --> 01:05:07,194 - Titan did not reveal itself 1378 01:05:07,195 --> 01:05:08,991 to the camera's of the Voyager. 1379 01:05:08,992 --> 01:05:11,240 But the spectrometers and radio science 1380 01:05:11,241 --> 01:05:13,992 made major contributions to the chemistry 1381 01:05:13,993 --> 01:05:17,918 and physics of the atmosphere and the interior. 1382 01:05:23,002 --> 01:05:24,253 - We had gathered what we could 1383 01:05:24,254 --> 01:05:26,338 with Voyager spacecraft. 1384 01:05:26,339 --> 01:05:28,307 - There was little to be gained 1385 01:05:28,308 --> 01:05:31,260 by doing another close flyby of Titan. 1386 01:05:31,261 --> 01:05:32,678 - Shortly after that, 1387 01:05:32,679 --> 01:05:33,974 NASA Headquarters agreed 1388 01:05:33,975 --> 01:05:35,940 that we should continue with Voyager Two 1389 01:05:35,941 --> 01:05:37,724 on it's Uranus trajectory. 1390 01:05:37,725 --> 01:05:40,103 So Voyager One had succeeded. 1391 01:05:41,729 --> 01:05:43,197 - People don't realise how we almost didn't 1392 01:05:43,198 --> 01:05:45,441 have that mission to Uranus and Neptune. 1393 01:05:45,442 --> 01:05:47,240 We almost didn't have the Grand Tour 1394 01:05:47,241 --> 01:05:50,904 if not for the success for Voyager One at Titan. 1395 01:05:50,905 --> 01:05:54,199 - Voyager One was done and was receding from 1396 01:05:54,200 --> 01:05:56,294 the solar system at an angle above the 1397 01:05:56,295 --> 01:05:58,038 plain of the planets. 1398 01:05:59,080 --> 01:06:01,799 - So Voyager One planetary mission almost 1399 01:06:01,800 --> 01:06:03,293 ended right there. 1400 01:06:04,502 --> 01:06:06,295 Come back to that later. 1401 01:06:17,390 --> 01:06:19,016 We're getting pictures and other data 1402 01:06:19,017 --> 01:06:20,356 back from Voyager Two. 1403 01:06:20,357 --> 01:06:21,727 But at some point in time, 1404 01:06:21,728 --> 01:06:23,524 it had to go behind the planet 1405 01:06:23,525 --> 01:06:25,567 and that blocks us from getting 1406 01:06:25,568 --> 01:06:27,361 radio signals to the earth. 1407 01:06:27,362 --> 01:06:29,452 And that happened to be in the middle of the night. 1408 01:06:29,453 --> 01:06:31,737 It appeared at times several hours 1409 01:06:31,738 --> 01:06:32,990 that everybody knows we're gonna be out 1410 01:06:32,991 --> 01:06:34,785 of contact with the spacecraft. 1411 01:06:34,786 --> 01:06:36,992 Everybody's expecting to pop champagne corks 1412 01:06:36,993 --> 01:06:38,586 and say "Hey we made it and all the data's 1413 01:06:38,587 --> 01:06:39,703 "on the tape recorder." 1414 01:06:39,704 --> 01:06:41,547 'Cause it could be transmitted to the earth. 1415 01:06:41,548 --> 01:06:44,333 And instead it pops out of the other side 1416 01:06:44,334 --> 01:06:46,460 and is all these crazy error signals 1417 01:06:46,461 --> 01:06:47,508 coming from the spacecraft. 1418 01:06:47,509 --> 01:06:48,801 Something bad has happened. 1419 01:06:51,299 --> 01:06:53,884 - Something happened right around ring-plane crossing, 1420 01:06:53,885 --> 01:06:55,808 and the images that were coming back were blank. 1421 01:07:00,266 --> 01:07:01,642 - People had thought maybe it crashed 1422 01:07:01,643 --> 01:07:02,940 into the rings of Saturn. 1423 01:07:02,941 --> 01:07:05,229 Is this it, is it dead? 1424 01:07:10,568 --> 01:07:14,493 - Ladies and gentlemen we can start debriefing. 1425 01:07:15,448 --> 01:07:17,913 I wanted to make a very brief statement. 1426 01:07:17,914 --> 01:07:20,788 We do have a problem onboard the Voyager Two spacecraft. 1427 01:07:20,789 --> 01:07:22,376 - The spacecraft has a problem. 1428 01:07:22,377 --> 01:07:24,837 The scan platform operating mechanism 1429 01:07:24,838 --> 01:07:26,500 is not operating properly. 1430 01:07:26,501 --> 01:07:27,876 - And make sure we understand where 1431 01:07:27,877 --> 01:07:29,378 we're headed if the following instruments 1432 01:07:29,379 --> 01:07:31,218 are mounted on the platform. 1433 01:07:31,219 --> 01:07:33,804 The wide-angle camera, the narrow-angle camera, 1434 01:07:33,805 --> 01:07:36,891 the infrared instrument, the ultraviolet instrument, 1435 01:07:36,892 --> 01:07:38,433 and the photopolarimeter. 1436 01:07:38,434 --> 01:07:41,139 - Yeah, that was the darkest, 1437 01:07:41,140 --> 01:07:43,605 the darkest day of the whole mission. 1438 01:07:43,606 --> 01:07:45,602 - There is circumstantial evidence. 1439 01:07:45,603 --> 01:07:47,856 - I came into the auditorium, 1440 01:07:47,857 --> 01:07:51,858 and there was just gloom on everybody's face. 1441 01:07:51,859 --> 01:07:53,610 - You're beginning to speculate. 1442 01:07:53,611 --> 01:07:56,530 - I quickly learned what had happened. 1443 01:07:56,531 --> 01:07:58,909 The scan platform had frozen. 1444 01:07:59,826 --> 01:08:01,294 - We were moving our scan platform 1445 01:08:01,295 --> 01:08:02,744 all over the sky. 1446 01:08:02,745 --> 01:08:04,997 And we're actually going as fast 1447 01:08:04,998 --> 01:08:07,165 as it could possibly go. 1448 01:08:07,166 --> 01:08:09,334 - A frozen scan platform 1449 01:08:09,335 --> 01:08:12,179 could be a fatal, crippling event. 1450 01:08:19,470 --> 01:08:21,188 - The rest of the Saturn mission, 1451 01:08:21,189 --> 01:08:23,933 and Uranus and Neptune were dead. 1452 01:08:24,976 --> 01:08:29,152 And seeing everything that we were planning just gone, 1453 01:08:30,815 --> 01:08:32,441 just suddenly gone. 1454 01:08:32,442 --> 01:08:34,113 - The problem is not with the camera, 1455 01:08:34,114 --> 01:08:36,031 it's with the articulated platform 1456 01:08:36,032 --> 01:08:37,863 that moves all of the instruments. 1457 01:08:37,864 --> 01:08:39,116 Our camera is, as far as we know, 1458 01:08:39,117 --> 01:08:40,198 are working just fine. 1459 01:08:40,199 --> 01:08:41,792 It's just that we're taking lots of pictures 1460 01:08:41,793 --> 01:08:43,036 of black space. 1461 01:08:44,120 --> 01:08:45,918 - All of the science that we had hoped to do, 1462 01:08:45,919 --> 01:08:48,624 and Uranus and Neptune, there were no other spacecraft 1463 01:08:48,625 --> 01:08:49,842 that were going to be going there. 1464 01:08:49,843 --> 01:08:51,379 It was up to Voyager to do it, 1465 01:08:51,380 --> 01:08:53,342 and all of a sudden it looked as though Voyager 1466 01:08:53,343 --> 01:08:54,840 was not going to do it. 1467 01:08:54,841 --> 01:08:57,092 It was devastating, it was. 1468 01:09:02,180 --> 01:09:04,056 - It took a couple of days while the 1469 01:09:04,057 --> 01:09:08,018 engineering team went to work diagnosing the problem. 1470 01:09:08,019 --> 01:09:10,397 - We are going to command an azimuth slew 1471 01:09:10,398 --> 01:09:12,648 and an elevation slew 1472 01:09:12,649 --> 01:09:14,358 to the Saturn position. 1473 01:09:14,359 --> 01:09:15,948 - It turns out the scan platform 1474 01:09:15,949 --> 01:09:17,819 has small motors to rotate it, 1475 01:09:17,820 --> 01:09:19,446 and we could run it at slow speed. 1476 01:09:19,447 --> 01:09:20,869 Tick, tick, tick, tick. 1477 01:09:20,870 --> 01:09:23,742 Fast medium speed or very fast. 1478 01:09:23,743 --> 01:09:25,871 We were of course wanting to look at lots of places, 1479 01:09:25,872 --> 01:09:28,339 so we had the thing looking lots of places, 1480 01:09:28,340 --> 01:09:32,876 and the lubrication wasn't adequate and it just jammed. 1481 01:09:32,877 --> 01:09:35,754 - It was frozen sort of like a car 1482 01:09:35,755 --> 01:09:37,798 stuck in the snow. 1483 01:09:37,799 --> 01:09:39,675 You try to go forward or backward little bit 1484 01:09:39,676 --> 01:09:42,886 and keep working on it and try to get it out, 1485 01:09:42,887 --> 01:09:44,388 and that's what we did with the scan platform. 1486 01:09:44,389 --> 01:09:47,104 We would try to push it a little bit in one direction 1487 01:09:47,105 --> 01:09:48,558 and it would yield a little bit, 1488 01:09:48,559 --> 01:09:50,232 and then we'd push it in the other direction, 1489 01:09:50,233 --> 01:09:51,942 and it would yield a little bit more, 1490 01:09:51,943 --> 01:09:53,110 and then we kept doing that 1491 01:09:53,111 --> 01:09:55,315 back and forth, back and forth. 1492 01:09:55,316 --> 01:09:57,526 And finally that was enough 1493 01:09:57,527 --> 01:10:00,701 to get the lubrication into the gears. 1494 01:10:01,739 --> 01:10:03,365 - It was freed up 1495 01:10:03,366 --> 01:10:04,834 and back came the spacecraft, 1496 01:10:04,835 --> 01:10:07,160 and back came the imaging system, 1497 01:10:07,161 --> 01:10:09,584 and there was Saturn on exit. 1498 01:10:14,252 --> 01:10:15,048 - Yeah. 1499 01:10:23,177 --> 01:10:25,429 - We were looking at the shadow of Saturn 1500 01:10:25,430 --> 01:10:26,555 on the rings. 1501 01:10:26,556 --> 01:10:31,226 And it was clearly from this wild, crazy angle. 1502 01:10:31,227 --> 01:10:32,103 Wow. 1503 01:10:32,104 --> 01:10:35,778 Holy cow, we're on the other side of Saturn. 1504 01:10:37,150 --> 01:10:38,902 ♫ Us ♫ 1505 01:10:42,864 --> 01:10:45,117 ♫ And them ♫ 1506 01:10:51,330 --> 01:10:54,925 ♫ And after all we're only ♫ 1507 01:10:56,586 --> 01:10:59,171 ♫ Ordinary men ♫ 1508 01:10:59,172 --> 01:11:01,256 - We felt like we were there. 1509 01:11:01,257 --> 01:11:03,680 Nobody even thought about it. 1510 01:11:05,261 --> 01:11:07,184 Voyager was part of us. 1511 01:11:08,222 --> 01:11:09,473 We. 1512 01:11:09,474 --> 01:11:11,226 ♫ Me ♫ 1513 01:11:15,271 --> 01:11:17,444 ♫ And you ♫ 1514 01:11:22,904 --> 01:11:24,747 - All of planetary exploration to me 1515 01:11:24,748 --> 01:11:27,115 is a story about longing. 1516 01:11:27,116 --> 01:11:29,576 It's a longing to know ourselves. 1517 01:11:29,577 --> 01:11:31,328 It's a longing to understand 1518 01:11:31,329 --> 01:11:33,914 the significance of our own existence. 1519 01:11:33,915 --> 01:11:35,499 It's a longing to communicate, 1520 01:11:35,500 --> 01:11:36,467 to say to the universe 1521 01:11:36,468 --> 01:11:38,794 we're here, you know, know us. 1522 01:11:38,795 --> 01:11:40,797 You know, where are you? 1523 01:11:41,798 --> 01:11:44,758 ♫ Forward he cried ♫ 1524 01:11:44,759 --> 01:11:46,218 ♫ From the rear and ♫ 1525 01:11:46,219 --> 01:11:49,348 ♫ The front rank died ♫ 1526 01:11:52,517 --> 01:11:54,315 - How would you go about trying 1527 01:11:54,316 --> 01:11:58,939 to communicate with a totally alien civilization? 1528 01:11:58,940 --> 01:12:00,192 - The assumption is that we 1529 01:12:00,193 --> 01:12:02,192 share the same physical universe. 1530 01:12:02,193 --> 01:12:04,321 That the laws of physics here on earth 1531 01:12:04,322 --> 01:12:06,780 seem to be applicable everywhere. 1532 01:12:06,781 --> 01:12:08,829 Science and math will be something 1533 01:12:08,830 --> 01:12:12,619 that we can communicate with them fairly easily. 1534 01:12:12,620 --> 01:12:15,539 - Humans universally love music. 1535 01:12:15,540 --> 01:12:18,416 And so the record says we like this stuff. 1536 01:12:18,417 --> 01:12:21,753 And we sent it out as a kind of gift for you. 1537 01:12:21,754 --> 01:12:25,340 Beneath that there are mathematical structure. 1538 01:12:25,341 --> 01:12:27,968 The mathematical structure of a straight pop song 1539 01:12:27,969 --> 01:12:30,015 is pretty simple, it's like arithmetic. 1540 01:12:30,016 --> 01:12:32,764 The mathematical structure of a Bach Fugue 1541 01:12:32,765 --> 01:12:35,517 is much more complicated and rewarding to attention. 1542 01:12:35,518 --> 01:12:39,396 Mathematics really is a universal language. 1543 01:12:39,397 --> 01:12:41,365 So we did make sure that the record 1544 01:12:41,366 --> 01:12:45,527 included music that would reward mathematical study. 1545 01:12:54,495 --> 01:12:55,542 - I have concerns. 1546 01:12:55,543 --> 01:12:59,124 I mean we have intelligent life on our own planet. 1547 01:12:59,125 --> 01:13:01,501 Dolphins and whales that we don't 1548 01:13:01,502 --> 01:13:04,754 communicate with, we cannot communicate with. 1549 01:13:04,755 --> 01:13:07,008 Other than tricks for fish. 1550 01:13:11,304 --> 01:13:13,557 It's a little conceited to think that 1551 01:13:13,558 --> 01:13:14,808 it's gonna be like Star Trek 1552 01:13:14,809 --> 01:13:17,267 and if we find some advance life 1553 01:13:17,268 --> 01:13:19,111 that we'll immediately 1554 01:13:20,062 --> 01:13:22,190 sit down for tea together or something. 1555 01:13:22,191 --> 01:13:25,442 It's not gonna be that simple. 1556 01:13:27,320 --> 01:13:30,620 - So the Voyager record has a set of pictures on it 1557 01:13:30,621 --> 01:13:32,824 that depicts our civilization. 1558 01:13:32,825 --> 01:13:36,204 But we only had the ability to do about 100 pictures, 1559 01:13:36,205 --> 01:13:38,455 that was as much data as we could send. 1560 01:13:38,456 --> 01:13:40,498 So that was kind of hard. 1561 01:13:40,499 --> 01:13:42,500 - It was a process of distillation. 1562 01:13:42,501 --> 01:13:46,004 You can't describe the Earth in 100 pictures. 1563 01:13:46,005 --> 01:13:48,599 You can't describe the Earth in a thousand pictures. 1564 01:13:48,600 --> 01:13:50,508 But what art is about 1565 01:13:50,509 --> 01:13:53,228 is taking something that's small 1566 01:13:54,096 --> 01:13:56,097 but can represent the whole. 1567 01:14:07,234 --> 01:14:08,823 - We thought it was very important 1568 01:14:08,824 --> 01:14:11,698 to put some pictures of humans nude on the record 1569 01:14:11,699 --> 01:14:15,617 to show just what our anatomy was really like. 1570 01:14:15,618 --> 01:14:19,079 NASA had been seriously criticised 1571 01:14:19,080 --> 01:14:21,039 about the Pioneer plaque. 1572 01:14:21,040 --> 01:14:23,667 There were actually letters to the editors of newspapers 1573 01:14:23,668 --> 01:14:27,298 saying that NASA was sending smut to space. 1574 01:14:28,631 --> 01:14:30,053 How are we going to show pictures of 1575 01:14:30,054 --> 01:14:33,551 naked humans without it looking salacious? 1576 01:14:33,552 --> 01:14:35,395 And the answer to that was why don't 1577 01:14:35,396 --> 01:14:38,060 you put a pregnant woman in the picture. 1578 01:14:38,061 --> 01:14:41,436 Because pregnant women are not considered salacious. 1579 01:14:41,437 --> 01:14:44,104 Not appealing sexually. 1580 01:14:44,105 --> 01:14:46,189 So that's what we did. 1581 01:14:46,190 --> 01:14:47,908 - And I figured if this doesn't get passed NASA 1582 01:14:47,909 --> 01:14:49,364 nothing's getting passed NASA. 1583 01:14:49,365 --> 01:14:50,986 And I guess the answer was nothing's 1584 01:14:50,987 --> 01:14:54,207 getting passed NASA because it was the only picture 1585 01:14:54,208 --> 01:14:56,451 that they made us take out. 1586 01:14:57,910 --> 01:15:02,247 - Now it's five years of cruising out to Uranus. 1587 01:15:02,248 --> 01:15:04,124 - Uranus will be the most remote object 1588 01:15:04,125 --> 01:15:06,042 yet visited by a spacecraft. 1589 01:15:06,043 --> 01:15:08,137 And it's so remote it was not even known 1590 01:15:08,138 --> 01:15:09,504 until 200 years ago. 1591 01:15:09,505 --> 01:15:11,047 And it's a great distance out there 1592 01:15:11,048 --> 01:15:12,391 and if we launch directly from earth 1593 01:15:12,392 --> 01:15:14,300 it would have taken 30 years to get there. 1594 01:15:14,301 --> 01:15:15,894 So we're very fortunate that we can swing 1595 01:15:15,895 --> 01:15:18,138 by Jupiter and Saturn on our way. 1596 01:15:18,139 --> 01:15:20,473 - I can always say that as an observational astronomer 1597 01:15:20,474 --> 01:15:21,896 I've been trying to figure this thing out 1598 01:15:21,897 --> 01:15:23,235 for the past 25 years 1599 01:15:23,236 --> 01:15:26,229 and it's very frustrating in a telescope 1600 01:15:26,230 --> 01:15:27,944 to look at that tiny little disc 1601 01:15:27,945 --> 01:15:30,530 and try to determine anything about it. 1602 01:15:30,531 --> 01:15:32,199 For me the next few days are gonna 1603 01:15:32,200 --> 01:15:33,778 be very exciting. 1604 01:15:39,869 --> 01:15:42,162 - Once we got beyond Saturn, 1605 01:15:42,163 --> 01:15:45,212 essentially the engineers threw out the rule book 1606 01:15:45,213 --> 01:15:48,626 and said, "How are we gonna make this work? 1607 01:15:48,627 --> 01:15:52,047 "How are we gonna take pictures of planets 1608 01:15:52,048 --> 01:15:54,674 "this far from the Sun?" 1609 01:15:54,675 --> 01:15:58,100 - Voyager was the first of a class of NASA spacecraft 1610 01:15:58,101 --> 01:16:00,180 that could be reprogrammed. 1611 01:16:00,181 --> 01:16:01,524 They could take what was on the computer 1612 01:16:01,525 --> 01:16:02,640 and just wipe it away 1613 01:16:02,641 --> 01:16:05,235 and give it a whole new set of software. 1614 01:16:05,236 --> 01:16:07,353 They trained the spacecraft to 1615 01:16:07,354 --> 01:16:09,564 pirouette like a ballet dancer. 1616 01:16:09,565 --> 01:16:11,533 Basically you want to take a picture of that thing 1617 01:16:11,534 --> 01:16:13,198 and it's going past you really fast, 1618 01:16:13,199 --> 01:16:16,196 so you spin the whole spacecraft 1619 01:16:16,197 --> 01:16:18,615 and follow it like this. 1620 01:16:18,616 --> 01:16:21,037 And so even though it was darker at Uranus 1621 01:16:21,038 --> 01:16:22,624 and really dark at Neptune, 1622 01:16:22,625 --> 01:16:25,373 you could leave the shutter open without smearing, 1623 01:16:25,374 --> 01:16:27,716 and that was just beautiful. 1624 01:16:28,834 --> 01:16:31,086 - We had all of the rich set of goodies 1625 01:16:31,087 --> 01:16:33,505 from Jupiter and from Saturn, 1626 01:16:33,506 --> 01:16:35,429 but Uranus was unknown. 1627 01:16:39,303 --> 01:16:40,976 - Our going on out to Uranus and Neptune 1628 01:16:40,977 --> 01:16:43,139 that was the first time. 1629 01:16:43,140 --> 01:16:44,729 We just had the one spacecraft so we 1630 01:16:44,730 --> 01:16:46,689 were more or less just flying blind 1631 01:16:46,690 --> 01:16:48,937 and we didn't get a second chance. 1632 01:16:49,980 --> 01:16:51,856 Nor will there be a second chance. 1633 01:16:51,857 --> 01:16:53,483 And I think for quite some time 1634 01:16:53,484 --> 01:16:55,407 it's very unlikely that 1635 01:16:56,654 --> 01:16:59,989 we'll all be dead and gone before 1636 01:16:59,990 --> 01:17:02,200 anyone goes back out there 1637 01:17:02,201 --> 01:17:04,452 to Uranus and Neptune again. 1638 01:17:22,555 --> 01:17:24,226 - It was like taking something 1639 01:17:24,227 --> 01:17:26,897 that was almost fictional, almost mythological, 1640 01:17:26,898 --> 01:17:29,896 and then seeing it as a real object. 1641 01:17:31,147 --> 01:17:33,443 - Spacecraft flew through that system like a bull's eye 1642 01:17:33,444 --> 01:17:35,655 because Uranus is tilted on its side, 1643 01:17:35,656 --> 01:17:38,945 with this beautiful aquamarine blue methane atmosphere, 1644 01:17:38,946 --> 01:17:39,946 and all these pictures, 1645 01:17:39,947 --> 01:17:41,573 every single one of them is like whoa! 1646 01:17:41,574 --> 01:17:43,702 And you could hear people just "Whoa!" 1647 01:17:43,703 --> 01:17:45,451 And everybody would be doing something 1648 01:17:45,452 --> 01:17:46,417 and somebody would go "Whoa!" 1649 01:17:46,418 --> 01:17:47,584 And everybody would turn and look up. 1650 01:17:47,585 --> 01:17:49,253 “Oh my gosh, look at that!" 1651 01:17:50,499 --> 01:17:51,375 There was no Internet, 1652 01:17:51,376 --> 01:17:55,211 there was no news stream going out to live CNN. 1653 01:17:55,212 --> 01:17:57,802 The only way to experience that sensation 1654 01:17:57,803 --> 01:18:00,722 of being one of only a small group of people 1655 01:18:00,723 --> 01:18:04,063 who saw a point of light become a world, 1656 01:18:05,181 --> 01:18:08,059 the only way to experience it was to be in that room. 1657 01:18:08,060 --> 01:18:10,185 - Well just about two minutes ago, 1658 01:18:10,186 --> 01:18:11,688 Voyager Two passed through 1659 01:18:11,689 --> 01:18:13,781 it's closest approach to Uranus. 1660 01:18:15,774 --> 01:18:18,118 - The new ring is 1661 01:18:18,944 --> 01:18:19,866 right here. 1662 01:18:20,946 --> 01:18:22,030 Now, I don't... 1663 01:18:23,407 --> 01:18:25,283 You're telling me you can't see it. 1664 01:18:25,284 --> 01:18:26,534 I can. 1665 01:18:26,535 --> 01:18:27,577 - Dr. Soderblom, 1666 01:18:27,578 --> 01:18:28,873 as you whizzed through your explanation, 1667 01:18:28,874 --> 01:18:30,043 I couldn't put it all together, 1668 01:18:30,044 --> 01:18:32,916 could you try that again? 1669 01:18:32,917 --> 01:18:33,759 - Slower? 1670 01:18:34,668 --> 01:18:36,261 - Slower and a few more details. 1671 01:18:36,262 --> 01:18:39,006 - I thought that was pretty slow. 1672 01:18:41,717 --> 01:18:43,343 - Every time we arrived at a new planet 1673 01:18:43,344 --> 01:18:44,311 there were always surprises 1674 01:18:44,312 --> 01:18:46,349 even though we had gotten a lot smarter. 1675 01:18:46,350 --> 01:18:47,849 For instance, before Voyager, 1676 01:18:47,850 --> 01:18:49,270 all the magnetic fields 1677 01:18:49,271 --> 01:18:51,351 have the magnetic pole near 1678 01:18:51,352 --> 01:18:53,228 the rotation axis of the planet, 1679 01:18:53,229 --> 01:18:54,354 and that was true for Jupiter, 1680 01:18:54,355 --> 01:18:55,857 it was true for Saturn. 1681 01:18:55,858 --> 01:18:57,699 And then we flew by Uranus and 1682 01:18:57,700 --> 01:19:00,568 the pole was near the equator. 1683 01:19:00,569 --> 01:19:01,821 - There's been a lot of speculation 1684 01:19:01,822 --> 01:19:04,030 about the magnetosphere of Uranus. 1685 01:19:04,031 --> 01:19:04,953 Would there be one, 1686 01:19:04,954 --> 01:19:06,699 what would it be like? 1687 01:19:06,700 --> 01:19:08,122 And the magnetosphere of Uranus 1688 01:19:08,123 --> 01:19:11,079 is far more weird and wonderful. 1689 01:19:11,080 --> 01:19:13,748 We found the planet tipped on it's side, 1690 01:19:13,749 --> 01:19:16,089 but the magnetic field is then tipped 1691 01:19:16,090 --> 01:19:17,758 relative to the spin axis. 1692 01:19:17,759 --> 01:19:21,256 So you have this huge contortion 1693 01:19:21,257 --> 01:19:22,509 in the magnetic field 1694 01:19:22,510 --> 01:19:25,385 as the planet spins around. 1695 01:19:25,386 --> 01:19:26,928 Just bizarre. 1696 01:19:26,929 --> 01:19:29,933 Why on earth the magnetic field was so messed up, 1697 01:19:29,934 --> 01:19:31,149 we had no idea. 1698 01:19:32,643 --> 01:19:36,147 - At the time the Voyager Two spacecraft flew by Uranus 1699 01:19:36,148 --> 01:19:39,857 one pole of the planet was pointing at the Sun. 1700 01:19:39,858 --> 01:19:41,776 At that point in it's orbit, 1701 01:19:41,777 --> 01:19:44,320 it's atmosphere shuts down. 1702 01:19:44,321 --> 01:19:47,791 So the planet itself didn't look exciting. 1703 01:19:50,452 --> 01:19:53,579 And part of that is Uranus itself 1704 01:19:53,580 --> 01:19:55,999 holding it's secrets back. 1705 01:19:56,000 --> 01:19:59,174 - That had to be, I guess, one of the, 1706 01:20:00,587 --> 01:20:03,965 well, disappointments in that Uranus 1707 01:20:03,966 --> 01:20:06,139 was not more photogenic than it was. 1708 01:20:06,140 --> 01:20:08,433 It was actually pretty blah. 1709 01:20:09,346 --> 01:20:10,188 - Poor Uranus. 1710 01:20:11,974 --> 01:20:13,182 Poor Uranus. 1711 01:20:27,781 --> 01:20:30,158 - Uranus itself was not the character 1712 01:20:30,159 --> 01:20:32,082 that Saturn and Jupiter were. 1713 01:20:32,083 --> 01:20:34,579 It had very very subdued features. 1714 01:20:34,580 --> 01:20:37,498 The big stars of the Uranus encounter 1715 01:20:37,499 --> 01:20:38,967 were actually the moons. 1716 01:20:42,921 --> 01:20:44,093 - If you're going to go to Neptune, 1717 01:20:44,094 --> 01:20:47,263 you still have to use Uranus for gravity assist. 1718 01:20:47,264 --> 01:20:50,928 The gravity assist aiming point at Uranus 1719 01:20:50,929 --> 01:20:53,264 just happened to be pretty close 1720 01:20:53,265 --> 01:20:55,850 to the orbit of Miranda. 1721 01:20:55,851 --> 01:20:57,148 Now some of the science, Miranda is not 1722 01:20:57,149 --> 01:20:59,395 the largest moon of Uranus. 1723 01:20:59,396 --> 01:21:02,523 If Uranus has been the last stop, 1724 01:21:02,524 --> 01:21:03,524 the scientists might have wanted 1725 01:21:03,525 --> 01:21:05,360 to go to a larger moon, 1726 01:21:05,361 --> 01:21:06,829 which ironically, 1727 01:21:08,280 --> 01:21:09,405 I don't see how anything could have been 1728 01:21:09,406 --> 01:21:11,204 any more interesting than Miranda. 1729 01:21:15,329 --> 01:21:18,082 It looked like a jumbled-up mess. 1730 01:21:21,293 --> 01:21:23,883 - This moon looked like it had been ripped to pieces 1731 01:21:23,884 --> 01:21:26,339 and then just sort of shoved back together again. 1732 01:21:26,340 --> 01:21:27,216 - Whoa! 1733 01:21:27,216 --> 01:21:28,136 Come look at this. 1734 01:21:28,137 --> 01:21:29,430 - Going up to the screen and pointing and saying, 1735 01:21:29,431 --> 01:21:31,224 "Look at that, look at that." 1736 01:21:31,225 --> 01:21:34,097 - Nobody was ready for Miranda. 1737 01:21:34,098 --> 01:21:37,934 - In parts there were enormous cliffs and gashes 1738 01:21:37,935 --> 01:21:40,404 in which fault blocks had dropped down. 1739 01:21:40,405 --> 01:21:43,773 And one of them, you can see the edge of a cliff 1740 01:21:43,774 --> 01:21:44,696 that is so, 1741 01:21:46,276 --> 01:21:49,070 it's gotta be 10 kilometres tall. 1742 01:21:49,071 --> 01:21:51,656 Now the gravity on Miranda is so weak 1743 01:21:51,657 --> 01:21:54,409 that if you jumped off the edge of that cliff, 1744 01:21:54,410 --> 01:21:56,708 you could read the newspaper 1745 01:21:57,955 --> 01:21:59,332 on the way down. 1746 01:22:00,332 --> 01:22:04,419 You probably would fall for 20 minutes. 1747 01:22:04,420 --> 01:22:05,467 But when you hit the bottom you'd 1748 01:22:05,468 --> 01:22:07,009 still be going 100 miles an hour. 1749 01:22:07,010 --> 01:22:09,632 And so it probably wouldn't, 1750 01:22:09,633 --> 01:22:12,635 it would be the last newspaper you read. 1751 01:22:21,353 --> 01:22:23,229 - One of the things that we have to remember 1752 01:22:23,230 --> 01:22:27,150 about Uranus is it was a very sad time for everybody. 1753 01:22:27,151 --> 01:22:30,194 Because we were just about to 1754 01:22:30,195 --> 01:22:32,697 present all our results. 1755 01:22:32,698 --> 01:22:34,120 We were all about to have to the 1756 01:22:34,121 --> 01:22:36,960 big final finale press conference. 1757 01:22:38,912 --> 01:22:40,746 Came back from breakfast 1758 01:22:40,747 --> 01:22:42,590 and I went to go watch 1759 01:22:44,001 --> 01:22:45,546 the shuttle being launched. 1760 01:22:45,547 --> 01:22:47,717 - We have main engine start. 1761 01:22:47,718 --> 01:22:48,838 Four, three, 1762 01:22:48,839 --> 01:22:49,681 two, one. 1763 01:22:51,258 --> 01:22:53,092 And liftoff. 1764 01:22:53,093 --> 01:22:55,720 Liftoff of the 25th space shuttle mission 1765 01:22:55,721 --> 01:22:58,139 and it has cleared the tower. 1766 01:22:58,140 --> 01:23:00,108 - And we thought, "Okay great, we'll watch the shuttle 1767 01:23:00,109 --> 01:23:02,819 "launch and then we'll go to the press conference." 1768 01:23:02,820 --> 01:23:05,771 But of course that was Challenger. 1769 01:23:05,772 --> 01:23:06,648 - Engine throttling up. 1770 01:23:06,649 --> 01:23:08,316 Three engine now at 104%. 1771 01:23:08,317 --> 01:23:10,570 - Challenger, go with throttle up. 1772 01:23:10,571 --> 01:23:13,779 - Roger, go with throttle up. 1773 01:23:21,288 --> 01:23:23,461 - People were just like astonished, this gasp like, 1774 01:23:23,462 --> 01:23:24,499 "Oh my. 1775 01:23:24,500 --> 01:23:25,500 "Did you see that? 1776 01:23:25,501 --> 01:23:27,090 "Did it really blow up?" 1777 01:23:27,091 --> 01:23:28,961 Because we had stopped in our meeting 1778 01:23:28,962 --> 01:23:30,382 so everyone could watch it, 1779 01:23:30,383 --> 01:23:33,758 and then there was just silence, people were crying. 1780 01:23:35,344 --> 01:23:37,845 - Well, what can you say? 1781 01:23:37,846 --> 01:23:39,189 You knew right away that 1782 01:23:39,190 --> 01:23:42,141 a bunch of people were dead. 1783 01:23:42,142 --> 01:23:43,610 - Flight Throttle, go ahead. 1784 01:23:43,611 --> 01:23:47,072 - RSO reports vehicle exploded. 1785 01:23:48,815 --> 01:23:50,233 - COPY- 1786 01:23:50,234 --> 01:23:53,078 - And then of course they showed replays and replays 1787 01:23:53,079 --> 01:23:57,198 and replays over and over and over again. 1788 01:23:57,199 --> 01:23:59,200 - We have no downlink. 1789 01:23:59,201 --> 01:24:01,953 - Okay, everybody, just stay off the telephones. 1790 01:24:01,954 --> 01:24:03,627 Make sure you maintain all your data, 1791 01:24:03,628 --> 01:24:05,414 start pulling it together. 1792 01:24:05,415 --> 01:24:06,961 - The Challenger accident happened 1793 01:24:06,962 --> 01:24:08,673 as we were receding from Uranus. 1794 01:24:08,674 --> 01:24:11,716 I have this vivid memory of picture after picture 1795 01:24:11,717 --> 01:24:13,714 of the crescent Uranus coming back 1796 01:24:13,715 --> 01:24:16,514 and the replay of the Challenger explosion, 1797 01:24:16,515 --> 01:24:18,928 and it was just devastating. 1798 01:24:18,929 --> 01:24:22,390 - Today is a day for mourning and remembering. 1799 01:24:22,391 --> 01:24:24,018 Nancy and I are pained to the core 1800 01:24:24,019 --> 01:24:26,394 over the tragedy of the shuttle Challenger. 1801 01:24:26,395 --> 01:24:27,612 We know we share this pain 1802 01:24:27,613 --> 01:24:30,231 with all of the people of our country. 1803 01:24:30,232 --> 01:24:32,650 This is truly a national loss. 1804 01:24:32,651 --> 01:24:33,868 I know it's hard to understand, 1805 01:24:33,869 --> 01:24:37,280 but sometimes painful things like this happen. 1806 01:24:37,281 --> 01:24:38,533 It's all part of the process 1807 01:24:38,534 --> 01:24:41,075 of exploration and discovery. 1808 01:24:41,076 --> 01:24:42,952 It's all part of taking a chance 1809 01:24:42,953 --> 01:24:45,746 and expanding man's horizons. 1810 01:24:45,747 --> 01:24:48,958 The future doesn't belong to the faint hearted, 1811 01:24:48,959 --> 01:24:51,085 it belongs to the brave. 1812 01:24:51,086 --> 01:24:52,463 - Reports from the flight officer 1813 01:24:52,464 --> 01:24:55,172 indicate impact in the water. 1814 01:24:55,173 --> 01:24:58,134 Approximately 28.64 degrees north. 1815 01:24:58,135 --> 01:24:59,682 80.28 degrees west. 1816 01:25:06,018 --> 01:25:08,066 - During these closest approach time periods, 1817 01:25:08,067 --> 01:25:11,439 we would have hundreds of reporters come to JPL, 1818 01:25:11,440 --> 01:25:14,609 and it was great news atmosphere. 1819 01:25:14,610 --> 01:25:17,778 And when the Challenger exploded, 1820 01:25:17,779 --> 01:25:19,363 everybody just left. 1821 01:25:20,910 --> 01:25:23,251 - It was really a very sad time. 1822 01:25:23,252 --> 01:25:26,247 Sad ending to another great mission. 1823 01:25:35,380 --> 01:25:37,131 - Those cosmic questions we hope to learn 1824 01:25:37,132 --> 01:25:38,341 by sending our machines out, 1825 01:25:38,342 --> 01:25:39,309 the very same questions 1826 01:25:39,310 --> 01:25:41,554 that you and I and every child has asked themselves. 1827 01:25:41,555 --> 01:25:43,267 "Where do we come from, are we alone, 1828 01:25:43,268 --> 01:25:45,810 "what's the universe made of, how will it end?" 1829 01:25:45,811 --> 01:25:47,024 All of these basic questions 1830 01:25:47,025 --> 01:25:50,112 are the questions that drive science. 1831 01:25:53,649 --> 01:25:54,990 I do cosmology, I study the beginning 1832 01:25:54,991 --> 01:25:56,405 and end of the universe and sometimes people say, 1833 01:25:56,406 --> 01:25:57,652 "What's that good for?" 1834 01:25:57,653 --> 01:25:59,246 And I always say to them, "You don't ask what's a 1835 01:25:59,247 --> 01:26:00,910 "Mozart symphony good for? 1836 01:26:00,911 --> 01:26:02,740 "Or a Picasso painting.“ 1837 01:26:02,741 --> 01:26:04,617 But science somehow seems in order to be 1838 01:26:04,618 --> 01:26:06,746 useful for people it has to produce technology. 1839 01:26:06,747 --> 01:26:10,873 But the beautiful thing about science is the ideas. 1840 01:26:10,874 --> 01:26:13,542 From a child you ask your parents why. 1841 01:26:13,543 --> 01:26:14,919 But when you grow up you finally realise 1842 01:26:14,920 --> 01:26:17,673 that what you really mean is how. 1843 01:26:20,008 --> 01:26:21,759 Einstein has told us that us that space and time 1844 01:26:21,760 --> 01:26:23,427 are tied together. 1845 01:26:23,428 --> 01:26:26,263 Integrally, we live in a space time. 1846 01:26:26,264 --> 01:26:28,265 If our universe came into beings 1847 01:26:28,266 --> 01:26:31,315 and space popped into existence, then so did time. 1848 01:26:31,316 --> 01:26:34,230 And so time itself may not have existed 1849 01:26:34,231 --> 01:26:35,778 literally before the big bang. 1850 01:26:35,779 --> 01:26:37,483 So there was no before. 1851 01:26:37,484 --> 01:26:39,578 And that seems crazy, because if there was no before, 1852 01:26:39,579 --> 01:26:41,195 all these ideas of cause and effect 1853 01:26:41,196 --> 01:26:42,491 et cetera go out the window. 1854 01:26:42,492 --> 01:26:44,867 But all it means is that we'll have to change 1855 01:26:44,868 --> 01:26:46,617 the way we understand things. 1856 01:26:52,124 --> 01:26:53,791 Another possibility is that our Big Bang 1857 01:26:53,792 --> 01:26:55,543 is just one of an infinite number of Big Bang's 1858 01:26:55,544 --> 01:26:59,547 that are occurring in what we now call a multiverse. 1859 01:26:59,548 --> 01:27:01,841 It's an amazing change of view 1860 01:27:01,842 --> 01:27:04,138 which makes us yet even more insignificant. 1861 01:27:04,139 --> 01:27:05,932 We were insignificant enough travelling 1862 01:27:05,933 --> 01:27:07,555 around the Sun in the middle of nowhere 1863 01:27:07,556 --> 01:27:10,228 around a random galaxy amongst 100 billion galaxies, 1864 01:27:10,229 --> 01:27:12,353 but now we know that even the whole universe 1865 01:27:12,354 --> 01:27:15,604 that we call home may just be an insignificant 1866 01:27:15,605 --> 01:27:18,484 something in the midst of something much bigger. 1867 01:27:18,485 --> 01:27:20,484 The history of science is to remove us 1868 01:27:20,485 --> 01:27:24,115 ever further from the centre of the universe if you wish. 1869 01:27:24,116 --> 01:27:26,458 Or the centre of the action. 1870 01:27:33,206 --> 01:27:36,041 - Finally at Neptune, Voyager's begun 1871 01:27:36,042 --> 01:27:38,169 the last of a decades worth 1872 01:27:38,170 --> 01:27:40,385 of encounters with the outer planets. 1873 01:27:40,386 --> 01:27:42,303 - It was another three and a half years 1874 01:27:42,304 --> 01:27:44,091 to get out to Neptune. 1875 01:27:44,092 --> 01:27:46,260 They had to reprogram the spacecraft again, 1876 01:27:46,261 --> 01:27:47,558 give it, teach it some new tricks, 1877 01:27:47,559 --> 01:27:49,272 to work in this even darker environment, 1878 01:27:49,273 --> 01:27:51,266 even colder environment. 1879 01:27:52,142 --> 01:27:53,359 - If we take the Earth 1880 01:27:53,360 --> 01:27:55,269 being one astronomical unit 1881 01:27:55,270 --> 01:27:57,897 from the Sun, or AU for short. 1882 01:27:57,898 --> 01:28:00,274 Neptune is 30 times that distance. 1883 01:28:00,275 --> 01:28:01,447 - When we launched Voyager, 1884 01:28:01,448 --> 01:28:03,194 there was no capability to get 1885 01:28:03,195 --> 01:28:05,821 any images back from 30 AU. 1886 01:28:05,822 --> 01:28:08,949 That capability happened all after launch. 1887 01:28:08,950 --> 01:28:11,994 It involved reprogramming the spacecraft, 1888 01:28:11,995 --> 01:28:14,371 taking two 34-meter antennas 1889 01:28:14,372 --> 01:28:16,791 and adding them to a 70-meter antenna. 1890 01:28:16,792 --> 01:28:18,713 - Copy, we're ready to run that observation. 1891 01:28:18,714 --> 01:28:20,087 - It meant using the entire 1892 01:28:20,088 --> 01:28:21,884 very large array in New Mexico, 1893 01:28:21,885 --> 01:28:25,007 27 antennas to collect the very weak signal 1894 01:28:25,008 --> 01:28:27,510 that we could get back from 30 AU. 1895 01:28:27,511 --> 01:28:28,763 - The flybys past Jupiter, 1896 01:28:28,764 --> 01:28:31,477 Saturn, and Uranus, had sped up the spacecraft too, 1897 01:28:31,478 --> 01:28:32,975 so it's going even faster. 1898 01:28:32,976 --> 01:28:37,061 So enormous amounts of pressure, and one shot. 1899 01:28:47,364 --> 01:28:48,331 - There it was just sitting 1900 01:28:48,332 --> 01:28:49,868 out on the edge of our solar system 1901 01:28:49,869 --> 01:28:51,580 waiting for somebody to come out 1902 01:28:51,581 --> 01:28:53,202 and appreciate its beauty. 1903 01:28:53,203 --> 01:28:54,455 Just waiting for the day 1904 01:28:54,456 --> 01:28:58,254 that humans would get out there, and go "Wow!“ 1905 01:29:00,001 --> 01:29:01,093 - Neptune was photogenic 1906 01:29:01,094 --> 01:29:02,586 right from the beginning. 1907 01:29:02,587 --> 01:29:04,305 - I had been taking pictures of Neptune 1908 01:29:04,306 --> 01:29:07,469 from the ground where we couldn't see very much. 1909 01:29:07,470 --> 01:29:10,141 You know, in my head imagining what it might look like 1910 01:29:10,142 --> 01:29:14,974 and seeing that turned into reality, it's a rush. 1911 01:29:14,975 --> 01:29:16,898 - Looking at this blue, 1912 01:29:17,936 --> 01:29:19,937 bright blue orb. 1913 01:29:19,938 --> 01:29:22,690 In some ways it was evocative of the Earth, 1914 01:29:22,691 --> 01:29:25,734 which seemed very bizarre for the last 1915 01:29:25,735 --> 01:29:27,578 planet that we were flying by. 1916 01:29:34,286 --> 01:29:36,954 - I was a meticulous log taker 1917 01:29:36,955 --> 01:29:39,545 and I would make little notations in these logs 1918 01:29:39,546 --> 01:29:41,505 and I would draw little pictures, 1919 01:29:41,506 --> 01:29:43,754 and you could see what's this little dark spot, 1920 01:29:43,755 --> 01:29:46,338 bright clouds, I'm like wow! 1921 01:29:46,339 --> 01:29:47,215 WOW! 1922 01:29:47,215 --> 01:29:48,091 Exclamation point! 1923 01:29:48,092 --> 01:29:50,593 And I'd draw pictures and arrows. 1924 01:29:50,594 --> 01:29:52,344 The most surprising thing 1925 01:29:52,345 --> 01:29:54,188 was a giant dark spot. 1926 01:29:55,849 --> 01:29:58,142 Nobody had any idea that would be there. 1927 01:29:58,143 --> 01:29:59,019 It's huge! 1928 01:29:59,020 --> 01:30:01,103 It's like a hole in the planet. 1929 01:30:01,104 --> 01:30:03,689 So we called it The Great Dark Spot 1930 01:30:03,690 --> 01:30:06,364 because we're not very original when it comes to names. 1931 01:30:12,949 --> 01:30:15,202 - We had to basically make a forecast 1932 01:30:15,203 --> 01:30:19,038 of the storms on Neptune in order to point the cameras 1933 01:30:19,039 --> 01:30:20,581 during the last day. 1934 01:30:20,582 --> 01:30:22,124 And at the same time 1935 01:30:22,125 --> 01:30:23,584 there was a hurricane 1936 01:30:23,585 --> 01:30:26,045 off the east coast of the US, 1937 01:30:26,046 --> 01:30:28,589 and the weather forecasters 1938 01:30:28,590 --> 01:30:31,383 were trying to forecast that hurricane. 1939 01:30:32,261 --> 01:30:33,432 But they were trying to forecast 1940 01:30:33,433 --> 01:30:35,304 it 12 hours in advance 1941 01:30:35,305 --> 01:30:36,727 and they were having a lot of trouble 1942 01:30:36,728 --> 01:30:39,101 because the storm kept changing position. 1943 01:30:39,102 --> 01:30:41,068 And we were just calmly plotting 1944 01:30:41,069 --> 01:30:42,561 points on graph paper 1945 01:30:42,562 --> 01:30:44,906 and then say, “Okay, two weeks from now, 1946 01:30:44,907 --> 01:30:49,068 "this storm is going to be right here" and it usually was. 1947 01:30:53,531 --> 01:30:56,033 - At Jupiter, Saturn and Uranus, 1948 01:30:56,034 --> 01:30:58,661 the goal was to do a flyby 1949 01:30:58,662 --> 01:31:00,380 that would take the spacecraft 1950 01:31:00,381 --> 01:31:02,539 on to the next planet. 1951 01:31:02,540 --> 01:31:04,166 When it came to Neptune 1952 01:31:04,167 --> 01:31:06,168 we knew that that was the last planet 1953 01:31:06,169 --> 01:31:07,637 that we were going to fly by, 1954 01:31:07,638 --> 01:31:09,505 and so we could take 1955 01:31:09,506 --> 01:31:11,298 a different trajectory. 1956 01:31:11,299 --> 01:31:13,300 This allowed us to get a really 1957 01:31:13,301 --> 01:31:15,344 spectacular view of the rings 1958 01:31:15,345 --> 01:31:17,143 and then look back on the system 1959 01:31:17,144 --> 01:31:19,937 in a way that was quite beautiful. 1960 01:31:21,142 --> 01:31:23,814 - Think about imaging the rings of Neptune. 1961 01:31:23,815 --> 01:31:25,234 They have reflectivity which 1962 01:31:25,235 --> 01:31:27,272 is twice as dark as soot, 1963 01:31:27,273 --> 01:31:29,024 and the light that's falling on them 1964 01:31:29,025 --> 01:31:32,361 is 1,000 times fainter than on Earth. 1965 01:31:32,362 --> 01:31:34,405 So you have one one-thousandth the light 1966 01:31:34,406 --> 01:31:35,828 and you're trying to image something 1967 01:31:35,829 --> 01:31:37,497 which is twice as dark as soot 1968 01:31:37,498 --> 01:31:39,618 against a jet-black background. 1969 01:31:39,619 --> 01:31:41,578 - More than one ring could be 1970 01:31:41,579 --> 01:31:42,796 seen even in the raw images. 1971 01:31:42,797 --> 01:31:44,415 The so-called ring arcs. 1972 01:31:44,416 --> 01:31:48,091 And it seemed reasonable that this was indeed the lost arc 1973 01:31:48,092 --> 01:31:52,011 that our imaging team raiders were looking for. 1974 01:31:55,802 --> 01:31:57,270 Now you're going to turn on me, right? 1975 01:31:59,139 --> 01:32:01,140 - We knew at Neptune 1976 01:32:01,141 --> 01:32:03,684 we wanted a close flyby of Triton, 1977 01:32:03,685 --> 01:32:05,686 which was a huge world and a retrograde 1978 01:32:05,687 --> 01:32:07,980 orbit around Neptune. 1979 01:32:07,981 --> 01:32:09,574 - If you looked at them on the way in, 1980 01:32:09,575 --> 01:32:11,233 they weren't lined up. 1981 01:32:11,234 --> 01:32:14,278 One's up here and one's down here. 1982 01:32:14,279 --> 01:32:15,701 And so, what are you going to do? 1983 01:32:15,702 --> 01:32:17,614 Well, there was a way. 1984 01:32:17,615 --> 01:32:21,326 And the way was to fly over the north pole, 1985 01:32:21,327 --> 01:32:23,079 very close to Neptune 1986 01:32:23,955 --> 01:32:27,249 to bend the spacecraft so it would go down. 1987 01:32:27,250 --> 01:32:29,585 And then intersect Triton. 1988 01:32:29,586 --> 01:32:30,674 - But that meant getting to 1989 01:32:30,675 --> 01:32:32,138 within just a few thousand miles 1990 01:32:32,139 --> 01:32:33,380 of the cloud tops. 1991 01:32:33,381 --> 01:32:36,383 Which is like skimming the surface. 1992 01:32:36,384 --> 01:32:37,476 And they had to hit that, 1993 01:32:37,477 --> 01:32:39,471 you know, exactly right. 1994 01:32:40,388 --> 01:32:41,435 - There was a lot of concern 1995 01:32:41,436 --> 01:32:45,184 that we didn't know enough about Neptune's atmosphere 1996 01:32:45,185 --> 01:32:49,521 to really be sure that the spacecraft would not tumble. 1997 01:32:49,522 --> 01:32:51,320 It's also possible that there were particles 1998 01:32:51,321 --> 01:32:53,317 in these ring arcs that we might 1999 01:32:53,318 --> 01:32:55,652 go through a cloud of shrapnel. 2000 01:32:55,653 --> 01:32:57,747 And that would be the end of the spacecraft 2001 01:32:57,748 --> 01:32:58,956 if We did that. 2002 01:32:59,949 --> 01:33:02,326 - Just a slight error in the calculations 2003 01:33:02,327 --> 01:33:04,623 and instead of skimming across the cloud tops, 2004 01:33:04,624 --> 01:33:06,123 you're skimming into the clouds 2005 01:33:06,124 --> 01:33:08,123 and the spacecraft burns up. 2006 01:33:08,124 --> 01:33:09,500 Slight error the other way, 2007 01:33:09,501 --> 01:33:11,629 you go a little too far, you don't bend enough, 2008 01:33:11,630 --> 01:33:13,504 maybe you run right into Triton and crash, 2009 01:33:13,505 --> 01:33:15,422 and that's the end of the mission. 2010 01:33:15,423 --> 01:33:16,299 You don't have enough time, 2011 01:33:16,300 --> 01:33:19,009 you have to make your last best guess, 2012 01:33:19,010 --> 01:33:21,136 hit the send button. 2013 01:33:23,515 --> 01:33:24,979 It would have been just fascinating 2014 01:33:24,980 --> 01:33:27,564 to be hanging on to that spacecraft, right? 2015 01:33:27,565 --> 01:33:28,903 Skimming over these beautiful 2016 01:33:28,904 --> 01:33:31,355 blue cloud tops of Neptune. 2017 01:33:31,356 --> 01:33:33,529 And then as you come over the pole of Neptune 2018 01:33:33,530 --> 01:33:36,777 seeing that big moon Triton rise up... 2019 01:33:36,778 --> 01:33:39,782 VOYAGER PASSED A MERE 3,000 MILES ABOVE NEPTUNE'S NORTH POLE, ARRIVING WITH SPLIT SECOND ACCURACY. 2020 01:33:45,495 --> 01:33:47,585 -

When we did our portrait of each of the planets, 2173 01:40:48,336 --> 01:40:50,302 I was the first person to look at the pictures 2174 01:40:50,303 --> 01:40:52,170 and I knew every blemish, 2175 01:40:52,171 --> 01:40:53,842 and so I could pretty quickly go 2176 01:40:53,843 --> 01:40:55,307 blemish, blemish, blemish. 2177 01:40:55,308 --> 01:40:58,093 And I thought, "Well, where's the Earth?" 2178 01:40:58,094 --> 01:41:00,017 How could we, you know? 2179 01:41:00,888 --> 01:41:03,723 And then I realised there was a lot of, 2180 01:41:03,724 --> 01:41:08,103 there were a lot of streaks of light in that image, 2181 01:41:08,104 --> 01:41:10,146 and I realised finally 2182 01:41:10,147 --> 01:41:11,820 that the Earth was sitting 2183 01:41:11,821 --> 01:41:14,285 in one of those rays of light. 2184 01:41:15,736 --> 01:41:17,237 You know, I just sat there for a while 2185 01:41:17,238 --> 01:41:19,406 just kind of realising 2186 01:41:19,407 --> 01:41:22,075 "Wow, that's the Earth, you know, 2187 01:41:22,076 --> 01:41:24,494 “that's Voyager looking back at the Earth." 2188 01:41:24,495 --> 01:41:25,996 And then once I had sort of recovered, 2189 01:41:25,997 --> 01:41:27,249 I started calling people. 2190 01:41:27,250 --> 01:41:28,415 I called Brad. 2191 01:41:28,416 --> 01:41:29,292 Brad, "We got it." 2192 01:41:29,293 --> 01:41:31,209 Called Carl, “Carl, we got it.“ 2193 01:41:31,210 --> 01:41:32,132 Called my dad. 2194 01:41:33,796 --> 01:41:35,760 - And so this is a different kind of milestone 2195 01:41:35,761 --> 01:41:37,757 than the scientific milestones we've had. 2196 01:41:37,758 --> 01:41:39,676 One that is really symbolic. 2197 01:41:39,677 --> 01:41:40,724 - I'm an imaging scientist, 2198 01:41:40,725 --> 01:41:42,596 so I first realised, oh, this didn't turn out 2199 01:41:42,597 --> 01:41:44,440 the way we thought it was going to turn out, 2200 01:41:44,441 --> 01:41:47,267 and my first impulse is to take my hand 2201 01:41:47,268 --> 01:41:49,019 and wipe away the dust, 2202 01:41:49,020 --> 01:41:50,272 because there was some dust on it. 2203 01:41:50,273 --> 01:41:51,944 Well, one of the pieces of dust 2204 01:41:51,945 --> 01:41:55,734 that I wanted to wipe away was the Earth. 2205 01:41:55,735 --> 01:41:58,534 But it didn't matter because in the hands of Carl, 2206 01:41:58,535 --> 01:42:01,197 he turned it into an allegory 2207 01:42:01,198 --> 01:42:03,491 on the human condition. 2208 01:42:03,492 --> 01:42:05,210 - And the next slide. 2209 01:42:12,376 --> 01:42:13,918 The Earth in a sunbeam. 2210 01:42:16,505 --> 01:42:17,552 And in this colour picture 2211 01:42:17,553 --> 01:42:21,092 you can see that it is in fact less than a pixel, 2212 01:42:21,093 --> 01:42:23,219 and this is where we live, 2213 01:42:23,220 --> 01:42:25,013 on a blue dot. 2214 01:42:25,014 --> 01:42:26,436 On that blue dot. 2215 01:42:27,933 --> 01:42:30,685 That's where everyone you know 2216 01:42:30,686 --> 01:42:31,983 and everyone you ever heard of 2217 01:42:31,984 --> 01:42:34,814 and every human being who ever lived, 2218 01:42:34,815 --> 01:42:36,658 lived out their lives. 2219 01:42:38,569 --> 01:42:40,236 I think this perspective 2220 01:42:40,237 --> 01:42:43,031 underscores our responsibility 2221 01:42:43,032 --> 01:42:46,206 to preserve and cherish that blue dot, 2222 01:42:47,161 --> 01:42:49,004 the only home we have. 2223 01:42:50,289 --> 01:42:52,383 - My father talks about this little 2224 01:42:52,384 --> 01:42:55,418 tiny speck in this vast cosmic night. 2225 01:42:55,419 --> 01:42:58,171 And that we're part of something bigger. 2226 01:42:58,172 --> 01:43:00,340 And we're also alone. 2227 01:43:00,341 --> 01:43:01,684 There's a great thing where he says like 2228 01:43:01,685 --> 01:43:03,265 "There's no sign that any help is gonna 2229 01:43:03,266 --> 01:43:05,261 "come here to save us from ourselves. 2230 01:43:05,262 --> 01:43:06,805 “It's up to us." 2231 01:43:29,120 --> 01:43:31,084 - After Neptune the project continued 2232 01:43:31,085 --> 01:43:33,832 but it continued in quite a different way. 2233 01:43:33,833 --> 01:43:37,460 The Voyagers didn't have anymore encounters. 2234 01:43:37,461 --> 01:43:40,465 They were just sailing on out into interstellar space 2235 01:43:40,466 --> 01:43:42,465 which people didn't really understand 2236 01:43:42,466 --> 01:43:44,639 how far that was gonna be. 2237 01:43:47,388 --> 01:43:50,140 - At the time we were designing Voyager, 2238 01:43:50,141 --> 01:43:54,185 interstellar space, where the boundary was, 2239 01:43:54,186 --> 01:43:55,904 was totally unknown. 2240 01:43:56,731 --> 01:43:57,983 We had our eyes 2241 01:43:58,983 --> 01:44:00,447 on the interstellar mission. 2242 01:44:00,448 --> 01:44:02,821 Are we going to boost the spacecraft 2243 01:44:02,822 --> 01:44:04,821 to get out of our solar system 2244 01:44:04,822 --> 01:44:07,198 and into the galaxy? 2245 01:44:07,199 --> 01:44:08,450 It was a shot in the dark 2246 01:44:08,451 --> 01:44:10,795 because nobody knew how far. 2247 01:44:13,122 --> 01:44:14,544 Uncharted waters. 2248 01:44:15,750 --> 01:44:17,965 - Goldstone, Voyager race. 2249 01:44:17,966 --> 01:44:19,836 - Voyager race, Goldstone. 2250 01:44:19,837 --> 01:44:22,088 - Please turn command modulation on 2251 01:44:22,089 --> 01:44:22,931 at 1800. 2252 01:44:24,925 --> 01:44:28,803 - Goldstone copies 1800 for command. 2253 01:44:28,804 --> 01:44:31,139 - That is affirmed. 2254 01:44:52,995 --> 01:44:54,793 - We know the Sun has this gravitational influence 2255 01:44:54,794 --> 01:44:56,334 that goes way out, almost halfway 2256 01:44:56,335 --> 01:44:57,373 to the nearest star. 2257 01:44:57,374 --> 01:44:59,468 So in terms of gravity, the edge of the solar system 2258 01:44:59,469 --> 01:45:01,133 is gonna take Voyager 10s of thousands 2259 01:45:01,134 --> 01:45:02,879 of years to get there. 2260 01:45:02,880 --> 01:45:05,051 But, the magnetic field of the Sun 2261 01:45:05,052 --> 01:45:06,426 can only extend so far. 2262 01:45:06,427 --> 01:45:08,259 It's a bubble around our star. 2263 01:45:08,260 --> 01:45:09,182 All the stars have bubbles. 2264 01:45:09,183 --> 01:45:11,763 We can see the bubbles run other stars out there. 2265 01:45:11,764 --> 01:45:13,061 So we know that they have bubbles. 2266 01:45:13,062 --> 01:45:14,724 Where's our bubble end? 2267 01:45:14,725 --> 01:45:16,893 Where's the influence of the Sun 2268 01:45:16,894 --> 01:45:21,606 and it's magnetic field give way to the galaxy? 2269 01:45:21,607 --> 01:45:23,029 - We kept going and years went by 2270 01:45:23,030 --> 01:45:24,776 and years went by and we don't 2271 01:45:24,777 --> 01:45:27,654 detect the interstellar medium. 2272 01:45:32,827 --> 01:45:35,245 - Throughout the 1990s, 2273 01:45:35,246 --> 01:45:37,711 still didn't find the edge of the bubble. 2274 01:45:37,712 --> 01:45:40,208 Throughout the 2000s, still didn't find 2275 01:45:40,209 --> 01:45:41,876 the edge of the bubble, 2276 01:45:41,877 --> 01:45:45,713 and then finally in 2012 Voyager One, 2277 01:45:45,714 --> 01:45:46,761 which is going the fastest, 2278 01:45:46,762 --> 01:45:48,424 which is the farthest, 2279 01:45:48,425 --> 01:45:50,390 started to see these funny things happen 2280 01:45:50,391 --> 01:45:51,511 to the squiggly lines. 2281 01:45:51,512 --> 01:45:54,641 Did the magnetic field of the Sun change direction? 2282 01:45:54,642 --> 01:45:58,063 Change the kinds of particles it was trapping dramatically? 2283 01:45:58,064 --> 01:45:59,858 And they see this crazy spike. 2284 01:46:01,689 --> 01:46:02,689 Everybody goes, "Oh, is that it?" 2285 01:46:02,690 --> 01:46:04,899 And then it goes back to normal. 2286 01:46:04,900 --> 01:46:05,900 And then it was just literally 2287 01:46:05,901 --> 01:46:07,527 one magical day, 2288 01:46:07,528 --> 01:46:10,196 it was in August of 2012 2289 01:46:10,197 --> 01:46:12,407 that everything changed. 2290 01:46:12,408 --> 01:46:13,828 And it was like pffft, 2291 01:46:13,829 --> 01:46:15,622 just popped out of the bubble. 2292 01:46:15,623 --> 01:46:17,834 Voyager One has left our solar system. 2293 01:46:17,835 --> 01:46:19,375 It's the first thing built by humans 2294 01:46:19,376 --> 01:46:20,793 that has left our solar system 2295 01:46:20,794 --> 01:46:23,084 and now it's in interstellar space. 2296 01:46:23,085 --> 01:46:24,553 - Major historic announcement 2297 01:46:24,554 --> 01:46:26,138 by NASA just a short time ago 2298 01:46:26,139 --> 01:46:28,590 confirming the Voyager spacecraft, 2299 01:46:28,591 --> 01:46:30,309 Voyager, as in the thing that launched 2300 01:46:30,310 --> 01:46:33,219 way back in 1977 exploring the moons, 2301 01:46:33,220 --> 01:46:34,563 exploring the planets. 2302 01:46:34,564 --> 01:46:37,265 Well it has entered interstellar space. 2303 01:46:37,266 --> 01:46:38,688 - NASA says that Voyager One 2304 01:46:38,689 --> 01:46:41,185 has become the first manmade object 2305 01:46:41,186 --> 01:46:43,062 to reach interstellar space. 2306 01:46:43,063 --> 01:46:45,064 The cold dark region between stars. 2307 01:46:45,065 --> 01:46:47,066 - And we've slipped the outermost grasp 2308 01:46:47,067 --> 01:46:49,944 of our solar system with Voyager One. 2309 01:46:49,945 --> 01:46:51,616 The first human-made object 2310 01:46:51,617 --> 01:46:53,615 to venture into interstellar space. 2311 01:46:55,200 --> 01:46:56,245 - It's a wonderful achievement, actually. 2312 01:46:56,246 --> 01:46:57,495 When you think of it, it's historic, 2313 01:46:57,496 --> 01:47:00,079 it's our first step out of our bubble 2314 01:47:00,080 --> 01:47:02,582 which has been around all the planets 2315 01:47:02,583 --> 01:47:04,756 and around the Earth essentially forever. 2316 01:47:04,757 --> 01:47:07,045 And now finally some little 2317 01:47:07,046 --> 01:47:09,424 thing that we have built has left that bubble 2318 01:47:09,425 --> 01:47:12,634 and is in the space between the stars. 2319 01:47:12,635 --> 01:47:13,930 - I loved it when that happened. 2320 01:47:13,931 --> 01:47:17,057 It was like humanity has arrived into interstellar space 2321 01:47:17,058 --> 01:47:19,275 and we all feel like Voyager has carried 2322 01:47:19,276 --> 01:47:21,644 a bit of us into the galaxy. 2323 01:47:23,479 --> 01:47:25,647 -
