Would you like to inspect the original subtitles? These are the user uploaded subtitles that are being translated:
1
00:00:03,240 --> 00:00:06,080
The International Space Stationis, without question,
2
00:00:06,160 --> 00:00:08,560
the jewel in the crown of low-Earth orbit.
3
00:00:10,240 --> 00:00:13,600
Observation post, research lab,and classroom all in one.
4
00:00:18,400 --> 00:00:20,399
But many other assets orbiting Earth
5
00:00:20,479 --> 00:00:22,999
are even more importantto our everyday lives...
6
00:00:23,079 --> 00:00:25,919
delivering communications,weather observation,
7
00:00:25,999 --> 00:00:28,119
global positioningand resource management.
8
00:00:28,439 --> 00:00:30,359
And the list is growing every year.
9
00:01:18,758 --> 00:01:21,758
Chances are you are watchingthis program via satellite
10
00:01:21,838 --> 00:01:23,398
in one way or another,
11
00:01:23,478 --> 00:01:25,878
either transmitted directly or indirectly
12
00:01:25,958 --> 00:01:28,797
to your television, iPad, laptop or phone.
13
00:01:29,557 --> 00:01:33,357
In other words, you're using technologyonce considered science fiction.
14
00:01:37,357 --> 00:01:40,597
Pushing the envelope,technology must keep up with demand.
15
00:01:41,077 --> 00:01:44,877
More data,more reliability and real time connection.
16
00:01:51,357 --> 00:01:55,277
Space-destined hardware and technologyare on the cutting edge of science,
17
00:01:55,757 --> 00:01:59,197
often introducing new methodsof gathering scientific information.
18
00:02:03,716 --> 00:02:06,156
Demonstrator missionsare regularly sent up,
19
00:02:06,236 --> 00:02:09,996
flying new engineering solutionsto prove the hardware in situ,
20
00:02:10,076 --> 00:02:12,636
even without a specific goal in mind.
21
00:02:15,796 --> 00:02:19,076
Technology goes through
a whole development cycle
22
00:02:19,156 --> 00:02:21,396
which we call
the seamless train of innovation.
23
00:02:21,476 --> 00:02:25,996
We start from the idea
and we work along to develop it
24
00:02:26,076 --> 00:02:27,556
through our work in the labs,
25
00:02:27,636 --> 00:02:29,076
through the work of industry
26
00:02:29,596 --> 00:02:32,276
and especially of small
and medium industries,
27
00:02:32,356 --> 00:02:34,155
which are the vectors of innovation,
28
00:02:34,955 --> 00:02:39,195
but at the end, you need to prove
that it works in the real place, space.
29
00:02:39,275 --> 00:02:43,355
And in order to do that, we use missions
30
00:02:43,435 --> 00:02:47,155
that can take the risk
of flying unproven technology
31
00:02:47,235 --> 00:02:50,195
and demonstrate
to the larger missions that they work.
32
00:02:53,955 --> 00:02:57,915
Research laboratories focusingon the next generation of space hardware
33
00:02:57,995 --> 00:02:59,435
are dotted around the globe.
34
00:03:00,195 --> 00:03:03,075
The UK's Space Gateway, Harwell Campus,
35
00:03:03,155 --> 00:03:06,154
the ESA-RALAdvanced Manufacturing Laboratorysupports cutting-edge researchand development.
36
00:03:11,794 --> 00:03:13,154
The purpose
of the laboratory
37
00:03:13,234 --> 00:03:17,874
is, basically, to assess and pre-screen
candidate materials and processes
38
00:03:17,954 --> 00:03:19,474
for future space missions.
39
00:03:19,554 --> 00:03:23,074
So this will guide ESA
as well as the space community
40
00:03:23,154 --> 00:03:26,274
in focusing their technology investments
in the right area.
41
00:03:34,554 --> 00:03:37,554
The lab has extensiveon-site testing facilities,
42
00:03:37,634 --> 00:03:42,193
such as the ISIS Neutron Source,the Diamond Light Source synchrotron
43
00:03:42,273 --> 00:03:44,793
and the UK's Central Laser Facility.
44
00:03:57,233 --> 00:03:59,553
This year will bring the first launchof a satellite
45
00:03:59,633 --> 00:04:04,033
using the SmallGEO platform,Hispasat 36W-1.
46
00:04:05,033 --> 00:04:07,393
SmallGEO, a telecommunications platform
47
00:04:07,473 --> 00:04:10,353
accommodating a wide rangeof payloads and missions,
48
00:04:10,793 --> 00:04:14,072
has been developed in Germanyin a public-private partnership
49
00:04:14,152 --> 00:04:17,752
between ESA,OHB and the operator Hispasat.
50
00:04:19,712 --> 00:04:25,512
It’s indeed because
Hispasat and ESA were able to join forces
51
00:04:25,872 --> 00:04:30,032
that we were able to develop a satellite
with such a level of innovation.
52
00:04:30,112 --> 00:04:35,832
On the one hand, a new platform
with a new satellite prime contractor.
53
00:04:35,912 --> 00:04:41,992
On the other hand, a payload embarking,
also, a high level of innovation.
54
00:04:42,072 --> 00:04:47,991
And, all together,
this satellite has been developed.
55
00:04:48,311 --> 00:04:53,911
It's going to be flown
and will provide very innovative services.
56
00:04:53,991 --> 00:04:58,711
So, end to end,
the level of innovation is very high
57
00:04:58,791 --> 00:05:02,311
and, indeed,
separately neither Hispasat nor ESA
58
00:05:02,391 --> 00:05:06,311
would have been able to
undertake such a complex development.
59
00:05:09,631 --> 00:05:14,751
With a SmallGEO,
what we have tried to achieve was, really,
60
00:05:14,831 --> 00:05:20,630
to develop a new product in the low end
of the telecommunication market
61
00:05:20,710 --> 00:05:26,430
and, at the same time, this new product
would allow a new prime contractor
62
00:05:26,510 --> 00:05:30,550
to become a prominent player
of the satellite telecommunication market.
63
00:05:30,950 --> 00:05:34,550
That's the OHB, which is
the prime contractor of this satellite.
64
00:05:35,150 --> 00:05:39,390
This is a class of satellite that
only have electric propulsion on board,
65
00:05:39,470 --> 00:05:43,950
which is a highly efficient system that
allows achieving important mass savings.
66
00:05:44,190 --> 00:05:47,670
So, we are able
to put in space a satellite
67
00:05:47,750 --> 00:05:50,550
with a similar capacity
of a full chemical one,
68
00:05:50,630 --> 00:05:52,789
but with much lower mass,
69
00:05:52,869 --> 00:05:57,949
which means less launcher cost and
compatibility with more launch vehicles.
70
00:05:58,029 --> 00:06:01,269
And, again, this translates
into advantages for the operators
71
00:06:01,349 --> 00:06:03,149
who have at their disposal,
72
00:06:03,229 --> 00:06:05,709
more efficient technical solutions
for the mission.
73
00:06:05,789 --> 00:06:06,829
But is a very flexible,
74
00:06:06,909 --> 00:06:10,269
so it can also be used
for other geo stationary application.
75
00:06:15,869 --> 00:06:18,349
Another scheduled eventin the telecom area
76
00:06:18,429 --> 00:06:20,469
is the launch of EDRS-C.Expected by the end of the year.
77
00:06:23,189 --> 00:06:26,788
EDRS-C is also basedon the SmallGEO platform
78
00:06:26,868 --> 00:06:33,068
and will be the first dedicated satellitefor EDRS, the European Data Relay Service.
79
00:06:33,708 --> 00:06:37,628
It will be the second elementof the laser relay "space data highway".
80
00:06:38,828 --> 00:06:42,388
Low earth satellites encumberedwith line of sight communications
81
00:06:42,468 --> 00:06:46,868
can beam their data upwardto geosynchronous satellites via laser,
82
00:06:46,948 --> 00:06:50,788
which can then transmit the signalto ground stations at any time.
83
00:06:53,748 --> 00:06:57,788
The SmallGEO program
is just the first step for OHB.
84
00:06:58,667 --> 00:07:03,667
OHB has already sold a number
of other telecommunication satellites
85
00:07:03,747 --> 00:07:06,667
and, indeed,
this is the start of a product line
86
00:07:06,747 --> 00:07:10,547
that will evolve over time
like any other product lines
87
00:07:10,627 --> 00:07:14,827
of the other prime contractors
operating in the satellite telecom market.
88
00:07:24,587 --> 00:07:27,867
Another area of researchhas been in cost and time effectiveness
89
00:07:27,947 --> 00:07:29,467
in developing satellites.
90
00:07:30,067 --> 00:07:33,586
This has led to the CubeSat,several of which have flown in space.
91
00:07:34,466 --> 00:07:40,106
Measuring just 10 by 10 by 10 centimeters,these small cubes, or nano-satellites,
92
00:07:40,186 --> 00:07:41,866
have become extremely popular,
93
00:07:42,186 --> 00:07:43,706
opening up new possibilities
94
00:07:43,786 --> 00:07:47,706
for a wide range of groupspreviously unable to access space.
95
00:07:55,746 --> 00:08:01,346
We are a small group of students
with two professors and two coordinators
96
00:08:01,866 --> 00:08:07,225
and we have 52 students who did
their master's thesis on this project.
97
00:08:08,545 --> 00:08:13,465
It is a great project
for the students because it's the occasion
98
00:08:13,545 --> 00:08:15,665
to apply practical stuff.
99
00:08:15,745 --> 00:08:18,545
And not only the theoretical stuff
they have learned at school.
100
00:08:18,905 --> 00:08:22,585
Our satellite
is a telecommunications satellite.
101
00:08:22,665 --> 00:08:28,505
We use the D-STAR protocol for the radio
amateurs to communicate around the world.
102
00:08:35,545 --> 00:08:40,264
This is really a special moment
when we can see that, finally,
103
00:08:40,344 --> 00:08:47,144
the P-POD is installed on the platform
that will carry it to space
104
00:08:47,504 --> 00:08:49,184
on board the Soyuz launcher.
105
00:08:49,944 --> 00:08:53,944
So it's a great feeling to be
here in Kourou in French Guiana
106
00:08:54,024 --> 00:08:58,344
with the satellites almost
in space and, nominally, ready to work.
107
00:09:11,063 --> 00:09:12,863
Using off-the-shelf technology,
108
00:09:12,943 --> 00:09:15,703
CubeSats have been launched from the ISS
109
00:09:15,783 --> 00:09:18,583
and piggybackedonto other satellite launches.
110
00:09:18,943 --> 00:09:22,983
They will soon be deployed to Mars,asteroids and further afield.
111
00:09:34,223 --> 00:09:37,103
GPS is used every dayby people on the ground,
112
00:09:37,183 --> 00:09:40,303
thanks to global positioning satellitesfrom the United States.
113
00:09:40,903 --> 00:09:43,303
But GPS it is notthe only system in orbit.
114
00:09:43,863 --> 00:09:46,302
Russia has the GLONASS constellation,
115
00:09:46,622 --> 00:09:48,702
China have their own BeiDou system
116
00:09:48,982 --> 00:09:51,502
and Europe is buildingthe Galileo Network.
117
00:09:52,462 --> 00:09:55,542
The initial services is a stage
in the program
118
00:09:55,622 --> 00:10:00,102
whereby there is sufficient infrastructure
is made available in space,
119
00:10:00,182 --> 00:10:02,542
satellites around the globe,
who circle around.
120
00:10:03,462 --> 00:10:05,502
Plus infrastructure on the ground
121
00:10:05,582 --> 00:10:09,022
which control the satellites,
provides the navigation signals.
122
00:10:10,542 --> 00:10:15,782
Enough of that infrastructure is ready
so that the systems can be used.
123
00:10:16,262 --> 00:10:19,021
The use is still
not fully hundred percent,
124
00:10:19,101 --> 00:10:21,101
hence the word "initial" services.
125
00:10:26,101 --> 00:10:28,301
These constellationsare not exclusive.
126
00:10:28,861 --> 00:10:32,461
Galileo will also use the GPS systemfor even more accuracy
127
00:10:32,901 --> 00:10:35,261
and the U.S. is tying inwith the Russian GLONASS
128
00:10:35,341 --> 00:10:37,301
for extra-terrestrial services.
129
00:10:37,661 --> 00:10:39,861
In other words,they will enable spacecraft
130
00:10:39,941 --> 00:10:44,421
to utilize the positioning systemin almost any orbit around the Earth.
131
00:10:50,221 --> 00:10:51,180
Some of the signals
132
00:10:51,260 --> 00:10:55,460
are available only
during a certain percentage of the day
133
00:10:55,860 --> 00:10:59,020
the satellites move around
and not all of the day
134
00:10:59,100 --> 00:11:01,020
you have sufficient satellites in sight.
135
00:11:02,180 --> 00:11:03,620
But there is enough to start,
136
00:11:05,140 --> 00:11:08,220
and this is a very important moment
in the program,
137
00:11:08,300 --> 00:11:12,580
an excessively important moment,
because this actually shows to the world
138
00:11:12,660 --> 00:11:15,660
that the system is really going well,
139
00:11:16,220 --> 00:11:20,340
the performance we actually can provide
we know is excellent
140
00:11:20,780 --> 00:11:24,499
and, of course, we will continue
building out the full constellation,
141
00:11:24,579 --> 00:11:29,139
but the users can actually now
start using the satellite system.
142
00:11:32,419 --> 00:11:35,859
The European Galileonavigation system is nearing completion.
143
00:11:36,339 --> 00:11:38,419
More satelliteswill be launched this year,
144
00:11:38,699 --> 00:11:42,139
adding to a constellationwhich will eventually number 22.
145
00:11:43,219 --> 00:11:47,099
Under initial services
there will be three services provided.
146
00:11:47,179 --> 00:11:48,899
One is the so-called open service.
147
00:11:48,979 --> 00:11:50,619
This is for the mass market.
148
00:11:50,699 --> 00:11:54,139
This is where people will use
their smart phones,
149
00:11:54,219 --> 00:11:57,378
their navigation devices in cars
150
00:11:57,458 --> 00:12:03,618
which will have
Galileo-enabled chips inside
151
00:12:03,698 --> 00:12:08,018
which will receive
both Galileo and GPS in combination.
152
00:12:08,098 --> 00:12:10,018
And it is the combination
of the two systems
153
00:12:10,098 --> 00:12:13,418
which will be used
to determine the position of the user.
154
00:12:13,698 --> 00:12:17,338
Before ESA and the European Commission
when we started with satellite navigation
155
00:12:17,418 --> 00:12:20,058
it was, of course, not quite clear
156
00:12:20,138 --> 00:12:23,258
how really important
satellite navigation was going to be.
157
00:12:23,338 --> 00:12:26,778
And we had studies,
we had our insights in it,
158
00:12:27,218 --> 00:12:30,977
and we knew
that it would be important,
159
00:12:31,817 --> 00:12:34,137
but now we really see how important it is,
160
00:12:34,217 --> 00:12:37,017
particularly looking
in the future where we're gonna have...
161
00:12:38,577 --> 00:12:40,577
we're gonna need to have
162
00:12:40,657 --> 00:12:44,657
a sufficiently developed
satellite navigation infrastructure
163
00:12:44,737 --> 00:12:48,377
to support autonomous driving
and all sorts of other applications.
164
00:12:51,297 --> 00:12:54,537
NASA has already developedspecialized GPS receivers
165
00:12:54,617 --> 00:12:56,017
for space application.
166
00:12:56,697 --> 00:13:00,377
The Navigator Receiverfrom NASA's Goddard Space Flight Center
167
00:13:00,457 --> 00:13:04,416
first flew in 2009and proved to be very successful.
168
00:13:05,416 --> 00:13:09,056
A number of future missionsin HEO, GEO and MEO
169
00:13:09,136 --> 00:13:11,056
plan to work with this receiver,
170
00:13:11,136 --> 00:13:15,496
using its high sensitivity signalacquisition and tracking capabilities.
171
00:13:17,536 --> 00:13:21,336
NASA's JPL has alsodeveloped the BlackJack flight GPS,
172
00:13:22,296 --> 00:13:24,816
now being flown aboardan Argentine satellite
173
00:13:24,896 --> 00:13:28,896
the system looks at how the GPS radiosignal is distorted or delayed
174
00:13:28,976 --> 00:13:30,056
along its path.
175
00:13:30,816 --> 00:13:35,256
A typical GPS signal can plot a positionto within around 22 yards.
176
00:13:35,696 --> 00:13:39,535
BlackJack can pinpointits host satellite continuously
177
00:13:39,615 --> 00:13:42,055
to an accuracy of about one inch.
178
00:13:42,895 --> 00:13:44,775
Eighteen receivers are on orbit,
179
00:13:44,855 --> 00:13:49,535
while another system under development,called the Triple GNSS, or Tri-G,
180
00:13:49,615 --> 00:13:52,815
will be ableto track GPS and GNSS signals
181
00:13:52,895 --> 00:13:58,415
including the Russian GNSS and EuropeanGalileo navigation constellations.
182
00:14:15,574 --> 00:14:18,934
All of our spacefaring nationscontinue their Earth observation work
183
00:14:19,014 --> 00:14:21,534
in collaborationwith a number of organizations.
184
00:14:22,294 --> 00:14:26,294
The refinement of orbital positioningand unhindered high speed communications
185
00:14:26,574 --> 00:14:28,414
mean more new technologies craft
186
00:14:28,494 --> 00:14:31,574
are being addedto the armada of observation satellites.
187
00:14:41,974 --> 00:14:44,173
They include Europe's Copernicus Programme
188
00:14:44,253 --> 00:14:47,333
with no fewerthan three Sentinel satellite launches.
189
00:14:47,893 --> 00:14:50,253
In March, Sentinel-2B will be launched
190
00:14:50,333 --> 00:14:53,973
carrying a wide-swath,high-definition multispectral imager.
191
00:14:54,533 --> 00:14:56,853
With Sentinel-2A already on orbit,
192
00:14:56,933 --> 00:15:01,173
both Sentinel-2 satelliteswill monitor land cover, vegetation
193
00:15:01,253 --> 00:15:02,533
and water pollution.
194
00:15:03,453 --> 00:15:07,013
Now that we get Sentinel-2B
to fly together with Sentinel-2A
195
00:15:07,093 --> 00:15:09,493
there's a couple
of improvements that we get.
196
00:15:09,573 --> 00:15:13,493
So far, we have a revisit of ten days
with Sentinal-2B
197
00:15:13,573 --> 00:15:15,413
we will have a revisit of five days,
198
00:15:15,493 --> 00:15:18,052
that means we see every spot
on the Earth every five days.
199
00:15:18,412 --> 00:15:21,252
That will help, of course, also,
to avoid the clouds,
200
00:15:21,332 --> 00:15:23,852
or to have the chances higher
to have no clouds,
201
00:15:23,932 --> 00:15:25,772
in the various regions of the world.
202
00:15:26,492 --> 00:15:28,692
Both together Sentinal-2A and 2B
203
00:15:28,772 --> 00:15:32,532
will also improve the performance
of the services that are using the data.
204
00:15:32,892 --> 00:15:38,252
Sentinel-2B is contributing
to a constellation of Sentinel satellites
205
00:15:38,332 --> 00:15:43,812
which really provides data
over decades in different domains
206
00:15:43,892 --> 00:15:45,652
and with different instruments onboard.
207
00:15:45,732 --> 00:15:48,772
So, therefore, we're building up
a fully operational system
208
00:15:49,131 --> 00:15:51,651
which is enough incentive for industry
209
00:15:51,731 --> 00:15:54,571
to invest and to rely on
this information in the future.
210
00:16:00,291 --> 00:16:03,851
Sentinel-2A is already
supporting a lot of applications.
211
00:16:03,931 --> 00:16:06,611
They are ranging from,
for example, agricultural applications
212
00:16:06,691 --> 00:16:08,451
where we can do yield forecast,
213
00:16:08,731 --> 00:16:12,451
to forest monitoring where we,
for example, see deforestation.
214
00:16:12,731 --> 00:16:15,771
And besides that,
there is plenty of other applications
215
00:16:15,851 --> 00:16:20,331
like inland water where
we can look at the quality of the water.
216
00:16:20,411 --> 00:16:21,971
We can support river monitoring,
217
00:16:22,051 --> 00:16:28,010
but also coastal areas where we
look at changes in the coastal regions.
218
00:16:28,250 --> 00:16:32,810
On top of that, we recently changed, also,
to acquire the Antarctic regions,
219
00:16:32,890 --> 00:16:35,810
where we are, also,
now looking at ice and glaciers.
220
00:16:36,610 --> 00:16:38,850
Later in the yeartwo more Sentinels,
221
00:16:38,930 --> 00:16:42,130
Sentinel-5P and Sentinel-3B, will follow.
222
00:16:42,730 --> 00:16:45,090
The Sentinel-5 Precursor mission
223
00:16:45,170 --> 00:16:47,810
is a satellite dedicatedto monitoring our atmosphere
224
00:16:47,890 --> 00:16:50,490
at a high temporaland spectral resolution.
225
00:16:51,290 --> 00:16:54,290
It also offersincreased cloud-free observation.
226
00:16:54,610 --> 00:16:57,249
The second satellite,
which is a replica of the first one,
227
00:16:57,329 --> 00:17:00,849
is, of course,
shorter to develop and to test.
228
00:17:01,889 --> 00:17:03,889
The main thought when we developed
a new system,
229
00:17:03,969 --> 00:17:05,889
is put on the first spacecraft
230
00:17:05,969 --> 00:17:10,729
where you discover, basically, all
the early problems in equipment production
231
00:17:10,809 --> 00:17:13,489
software validation,
integration and test.
232
00:17:14,049 --> 00:17:18,569
All the specifications,
plans, test procedures are ready
233
00:17:18,649 --> 00:17:21,089
whenever you start building
the second spacecraft
234
00:17:21,169 --> 00:17:22,649
is, of course, a large benefit.
235
00:17:22,729 --> 00:17:26,489
The second spacecraft, let's say,
was realized in one and half year time.
236
00:17:26,769 --> 00:17:29,008
The cost, of course,
of a recurring spacecraft
237
00:17:29,088 --> 00:17:31,248
is much cheaper
than protoflight spacecraft.
238
00:17:31,328 --> 00:17:34,248
You could say, basically,
is 50% of the price of the first one.
239
00:17:37,688 --> 00:17:40,288
Sentinel-3Bis a multi-instrument mission
240
00:17:40,368 --> 00:17:42,488
to measure sea-surface topography,
241
00:17:42,568 --> 00:17:46,288
sea and land-surface temperatureand ocean and land color.
242
00:17:50,408 --> 00:17:55,928
We are addressing a number of issues that
relate to the development of new science
243
00:17:56,008 --> 00:17:57,368
but also operation missions.
244
00:17:57,448 --> 00:17:59,408
For example, the Earth Explorer missions,
245
00:17:59,488 --> 00:18:02,687
the scientific missions, but also
we are preparing the next generation
246
00:18:02,767 --> 00:18:04,447
of Sentinel missions for Copernicus.
247
00:18:10,087 --> 00:18:12,647
In the next five to ten years
in Earth observation,
248
00:18:12,727 --> 00:18:16,487
we will face a number of challenges,
some of them coming from outside.
249
00:18:16,567 --> 00:18:18,767
Dictator, constellations,
250
00:18:18,847 --> 00:18:21,087
commercial companies
entering our domain.
251
00:18:21,167 --> 00:18:24,887
And I think there we really have to see,
as ESA, as European Space Agency,
252
00:18:24,967 --> 00:18:29,527
a public institution, how we can
best react to these external challenges
253
00:18:29,607 --> 00:18:31,967
and position ourselves with our programs
254
00:18:32,047 --> 00:18:35,566
to really address these challenges
from our perspective.
255
00:18:46,366 --> 00:18:48,806
Demonstrating new lasertechnology,
256
00:18:48,886 --> 00:18:52,046
ESA is launchingthe ADM-Aeolus satellite.
257
00:18:52,486 --> 00:18:55,406
ADM standsfor Atmospheric Dynamics Mission.
258
00:18:55,846 --> 00:18:59,286
It will provide global observationof wind profiles.
259
00:18:59,806 --> 00:19:02,406
With this mission,ESA hopes to further our knowledge
260
00:19:02,486 --> 00:19:05,406
of the Earth’s atmosphereand weather systems.
261
00:19:24,845 --> 00:19:26,885
Space is a hazardous place.
262
00:19:27,285 --> 00:19:30,405
A key partof maintaining reliable satellite services
263
00:19:30,485 --> 00:19:32,285
is keeping a weather eye out.
264
00:19:39,485 --> 00:19:43,524
The Earth is constantly being bombardedby damaging solar storms
265
00:19:43,604 --> 00:19:46,124
and charged particlesejected from the Sun.
266
00:19:46,644 --> 00:19:48,204
This could knock out satellites
267
00:19:48,284 --> 00:19:51,924
and even communications systemsand power grids on the ground.
268
00:20:00,004 --> 00:20:01,084
Geomagnetic storms,
269
00:20:01,164 --> 00:20:03,724
solar x-ray and proton flux,
270
00:20:03,804 --> 00:20:05,124
coronal mass ejections,
271
00:20:05,204 --> 00:20:06,444
and sunspots...
272
00:20:06,524 --> 00:20:08,484
all are monitored continuously.
273
00:20:20,723 --> 00:20:23,243
The Earth is also surroundedby a cloud of debris
274
00:20:23,323 --> 00:20:25,803
from sixty yearsof human space activities.
275
00:20:26,363 --> 00:20:29,323
Space junkwhich could also damage satellites.
276
00:20:30,123 --> 00:20:34,083
Near-Earth objects also threaten the Earthand could collide with our planet.
277
00:20:45,723 --> 00:20:47,123
All these threats are monitored
278
00:20:47,203 --> 00:20:50,282
under ESA’sSpace Situational Awareness program,
279
00:20:50,362 --> 00:20:54,362
which the Operations Directoratehopes to see continuing to evolve.
280
00:21:11,882 --> 00:21:14,922
We want to protect our assets
in orbit and on Earth
281
00:21:15,002 --> 00:21:17,042
against impacts from space.
282
00:21:17,122 --> 00:21:22,121
Maybe from space weather
or risks from near-Earth objects
283
00:21:22,201 --> 00:21:26,201
and we also want
to protect our spacecraft in orbit
284
00:21:26,681 --> 00:21:29,641
from risks, for example,
coming from space debris.
285
00:21:33,281 --> 00:21:37,801
The Inter-Agency Space DebrisCoordination Committee, or IADC,
286
00:21:37,881 --> 00:21:42,321
is a forum of 14 nationsbrought together to exchange information
287
00:21:42,401 --> 00:21:45,241
and to research various aspectsof this problem.
288
00:21:46,081 --> 00:21:49,041
Numerous working groupsare studying methods of protection
289
00:21:49,121 --> 00:21:50,481
and threat mitigation.
290
00:22:00,160 --> 00:22:02,840
No matter what hardwareis orbiting Earthit can only make scientific observations.
291
00:22:06,800 --> 00:22:10,480
Only our human perceptionof the beauty that lies below
292
00:22:10,560 --> 00:22:14,400
can help us fully appreciatethe planet we call home.
