1
00:00:10,761 --> 00:00:12,229
From space,
2
00:00:12,304 --> 00:00:15,729
the view of our planet
3
00:00:15,849 --> 00:00:17,943
is breathtaking.
4
00:00:19,000 --> 00:00:25,074
5
00:00:31,448 --> 00:00:34,418
Satellites orbiting the Earth
6
00:00:34,535 --> 00:00:36,629
can now look down on it
7
00:00:36,745 --> 00:00:41,171
in absolutely extraordinary detail.
8
00:00:50,175 --> 00:00:53,019
Using cameras on the ground,
9
00:00:53,136 --> 00:00:54,558
in the air...
10
00:00:55,639 --> 00:00:57,687
and in space,
11
00:00:57,808 --> 00:01:00,061
we can tell the story of life on Earth
12
00:01:00,143 --> 00:01:03,113
from a brand-new perspective.
13
00:01:07,359 --> 00:01:10,408
At a time when the Earth's surface
is changing faster
14
00:01:10,529 --> 00:01:13,282
than at any point in human history...
15
00:01:15,075 --> 00:01:18,875
we can see
just what impact we're having.
16
00:01:24,626 --> 00:01:26,469
In this episode...
17
00:01:27,671 --> 00:01:29,765
satellites uncover
18
00:01:29,881 --> 00:01:32,805
previously unknown colonies of penguins...
19
00:01:38,390 --> 00:01:43,738
reveal mysterious ice rings
that could put seal pups in danger...
20
00:01:44,771 --> 00:01:47,445
and make surprising discoveries
21
00:01:47,566 --> 00:01:51,070
in Earth's most remote landscapes.
22
00:01:53,363 --> 00:01:55,411
Behind every image...
23
00:01:56,450 --> 00:01:57,872
there's a story.
24
00:02:00,954 --> 00:02:03,878
This is our home
25
00:02:03,999 --> 00:02:07,469
as we've never seen it before.
26
00:02:35,614 --> 00:02:37,833
At any given moment,
27
00:02:37,949 --> 00:02:41,249
over a thousand satellites
are orbiting the Earth.
28
00:02:47,918 --> 00:02:52,469
Some are capturing images
across the planet's surface so detailed...
29
00:02:54,549 --> 00:02:59,055
that we can now see
individual animals from space...
30
00:03:01,473 --> 00:03:06,024
while simultaneously following them
on the ground.
31
00:03:10,357 --> 00:03:12,701
Kenya, East Africa.
32
00:03:16,488 --> 00:03:18,161
The green of a river bank.
33
00:03:19,783 --> 00:03:23,663
Look closely,
and grey bodies are just visible.
34
00:03:25,872 --> 00:03:28,250
A family of elephants.
35
00:03:49,020 --> 00:03:50,567
They have a new calf...
36
00:03:51,732 --> 00:03:53,450
just over a week old.
37
00:04:05,454 --> 00:04:09,004
At around 100 kilos, and growing fast,
38
00:04:09,124 --> 00:04:13,095
she needs to drink
some 12 litres of milk a day.
39
00:04:18,675 --> 00:04:22,350
But her mother
is struggling to provide it for her.
40
00:04:24,222 --> 00:04:27,897
She hasn't fed properly in weeks.
41
00:04:33,774 --> 00:04:36,744
In fact, the whole herd is in trouble.
42
00:04:48,955 --> 00:04:52,835
And from space, it's clear why.
43
00:04:55,378 --> 00:04:57,176
At this time of year,
44
00:04:57,297 --> 00:05:01,052
the family is usually found
ten kilometres north,
45
00:05:01,176 --> 00:05:04,851
in the relative safety
of Samburu National Reserve.
46
00:05:07,516 --> 00:05:10,690
But satellite images reveal
that all is not well here.
47
00:05:15,023 --> 00:05:16,821
The ground is deep orange.
48
00:05:19,611 --> 00:05:21,204
Barely any signs of water...
49
00:05:22,322 --> 00:05:24,290
or green spots of vegetation.
50
00:05:32,874 --> 00:05:36,845
Samburu is in the grip
of a vicious drought.
51
00:05:42,425 --> 00:05:47,647
Northern Kenya has been struck hard
by the planet's changing climate.
52
00:05:54,020 --> 00:05:58,491
This year has seen 25% less rain
than the average.
53
00:05:59,860 --> 00:06:02,830
The dry season has been extreme.
54
00:06:06,741 --> 00:06:09,290
Animals are starving.
55
00:06:21,965 --> 00:06:24,138
A desperate search for food
56
00:06:24,259 --> 00:06:26,136
has forced the family
57
00:06:26,261 --> 00:06:28,104
out of the safety of the reserve...
58
00:06:29,806 --> 00:06:32,104
to a few small patches of green
59
00:06:32,225 --> 00:06:35,195
dangerously close to a busy main road.
60
00:06:48,450 --> 00:06:51,624
Scrubby vegetation provides
a little to eat.
61
00:06:53,163 --> 00:06:56,588
But here, the family could be a target
for poachers.
62
00:07:01,880 --> 00:07:05,180
On the ground,
their situation is desperate.
63
00:07:09,304 --> 00:07:12,023
But with cameras in space,
64
00:07:12,140 --> 00:07:15,440
we can see what the elephants can't.
65
00:07:20,023 --> 00:07:26,076
From a satellite taking an image
of the whole Earth every 15 minutes,
66
00:07:26,196 --> 00:07:28,290
we can track weather patterns.
67
00:07:35,705 --> 00:07:40,051
Over East Africa, clouds are building.
68
00:07:42,587 --> 00:07:45,716
Rain is just six days away.
69
00:07:56,142 --> 00:07:57,815
The calf is worn out.
70
00:08:06,403 --> 00:08:08,781
But her mother will not let her rest.
71
00:08:26,172 --> 00:08:29,722
It's not safe to be so close
to a busy road.
72
00:08:31,344 --> 00:08:32,891
They need to move on.
73
00:08:34,431 --> 00:08:35,808
But she's too tired.
74
00:09:10,717 --> 00:09:14,142
This is the first rain
she's ever experienced...
75
00:09:17,348 --> 00:09:18,975
and it's hard to get to grips with.
76
00:09:32,655 --> 00:09:35,204
Her mother encourages her to her feet.
77
00:09:40,163 --> 00:09:43,292
She wants her baby
out of this dangerous place.
78
00:09:57,680 --> 00:10:01,230
Samburu is transforming.
79
00:10:34,467 --> 00:10:37,186
Elephants, scattered by the drought,
80
00:10:37,262 --> 00:10:39,685
are now returning to the reserve.
81
00:10:43,309 --> 00:10:46,779
And our family is with them.
82
00:11:23,558 --> 00:11:27,563
Overnight,
one of the other females has given birth.
83
00:11:48,917 --> 00:11:51,045
The rain means the best start
84
00:11:51,169 --> 00:11:52,842
for a new generation
85
00:11:52,962 --> 00:11:55,385
of this vulnerable species.
86
00:12:24,744 --> 00:12:27,839
And it's not just elephants
we can see from space.
87
00:12:33,461 --> 00:12:37,341
Satellite cameras are finding animals
across the globe.
88
00:12:44,222 --> 00:12:46,896
The dunes of Namibia, Southern Africa.
89
00:12:50,019 --> 00:12:54,320
Tiny dark spots line the edge of the surf.
90
00:12:57,568 --> 00:13:00,196
Each one is a Cape fur seal...
91
00:13:03,241 --> 00:13:06,666
in a colony several thousand strong.
92
00:13:17,380 --> 00:13:19,974
Over the East African plains
of the Serengeti...
93
00:13:22,885 --> 00:13:27,186
scientists monitor
the size of wildebeest herds
94
00:13:27,265 --> 00:13:28,858
on their annual migration.
95
00:13:41,362 --> 00:13:44,787
From 600 kilometres above Baja, Mexico...
96
00:13:50,621 --> 00:13:53,750
we can see grey whales
97
00:13:53,875 --> 00:13:55,377
beneath the water...
98
00:13:57,754 --> 00:13:59,756
arriving here to give birth.
99
00:14:08,389 --> 00:14:13,065
This new technology
is now helping wildlife conservation
100
00:14:13,186 --> 00:14:15,439
in the most inaccessible places.
101
00:14:18,691 --> 00:14:19,863
Antarctica.
102
00:14:22,403 --> 00:14:25,498
A continent so hostile and remote...
103
00:14:27,200 --> 00:14:31,580
that studying life here
is incredibly challenging.
104
00:14:35,208 --> 00:14:41,341
But now satellites allow us to access
every square kilometre of its surface.
105
00:14:48,221 --> 00:14:52,317
And this has led
to an extraordinary discovery.
106
00:14:57,522 --> 00:15:01,618
Brown patches dotted across the ice.
107
00:15:03,569 --> 00:15:05,617
Seemingly out of place...
108
00:15:08,157 --> 00:15:09,909
but they are vital clues...
109
00:15:11,661 --> 00:15:16,132
helping us to find
one of our most iconic species.
110
00:15:36,269 --> 00:15:37,566
Emperor penguins.
111
00:15:47,029 --> 00:15:49,123
This colony is full of new life.
112
00:15:56,247 --> 00:15:58,545
Hatched just a month before,
113
00:15:58,624 --> 00:16:02,674
the chicks consume
pre-digested fish and krill
114
00:16:02,795 --> 00:16:04,468
brought to them by their parents.
115
00:16:09,802 --> 00:16:13,727
But the results of this diet can be messy.
116
00:16:37,205 --> 00:16:39,173
Over 10,000 birds
117
00:16:39,290 --> 00:16:41,088
create a vast amount...
118
00:16:42,752 --> 00:16:43,844
of poo.
119
00:16:52,011 --> 00:16:54,230
A problem for the colony.
120
00:16:59,519 --> 00:17:03,444
At minus 20,
all the water is frozen solid.
121
00:17:05,024 --> 00:17:06,321
With nothing to drink,
122
00:17:06,442 --> 00:17:09,742
penguins eat the snow
beneath their feet...
123
00:17:11,155 --> 00:17:13,624
which is becoming rather unappealing.
124
00:17:21,332 --> 00:17:23,255
They need to find fresh snow.
125
00:17:30,466 --> 00:17:31,809
The youngest chicks,
126
00:17:31,926 --> 00:17:33,529
who aren't yet able
to keep themselves warm,
127
00:17:33,553 --> 00:17:36,397
are carried on their parents' feet.
128
00:17:52,613 --> 00:17:55,583
Others should be walking by now.
129
00:18:06,627 --> 00:18:09,176
As each penguin moves
to find clean snow...
130
00:18:11,090 --> 00:18:15,015
the colony slowly works its way
across the ice...
131
00:18:24,520 --> 00:18:27,069
leaving a trail behind them.
132
00:18:32,361 --> 00:18:34,830
Over weeks, the patches spread.
133
00:18:37,366 --> 00:18:40,791
From space, a penguin colony
would be difficult to spot
134
00:18:40,911 --> 00:18:43,005
in this vast sea of white.
135
00:18:45,791 --> 00:18:48,590
But the marks they leave behind
stand out.
136
00:18:55,468 --> 00:18:59,223
And now that scientists know
what to look for,
137
00:18:59,347 --> 00:19:01,190
they are finding more colonies.
138
00:19:05,186 --> 00:19:10,488
So far, 26 new colonies
have been discovered...
139
00:19:14,862 --> 00:19:19,618
doubling the known global population
of the species.
140
00:19:23,204 --> 00:19:26,128
A discovery at a crucial time.
141
00:19:28,501 --> 00:19:32,551
It is predicted that the sea ice,
on which the penguins breed,
142
00:19:32,672 --> 00:19:35,016
will recede due to climate change.
143
00:19:37,968 --> 00:19:39,265
And as a consequence,
144
00:19:39,387 --> 00:19:43,938
20% of emperor penguins
could disappear in the next century.
145
00:19:49,814 --> 00:19:51,236
From satellite,
146
00:19:51,357 --> 00:19:54,782
scientists are now monitoring
these colonies
147
00:19:54,860 --> 00:19:57,113
as they face an uncertain future.
148
00:20:03,619 --> 00:20:08,090
The view from space is allowing us
to make scientific breakthroughs
149
00:20:08,207 --> 00:20:11,086
in the most remote places on the planet.
150
00:20:14,672 --> 00:20:20,270
In 2017, cameras captured a crack
in the Antarctic ice shelf...
151
00:20:23,222 --> 00:20:26,021
".450 metres wide...
152
00:20:29,437 --> 00:20:32,361
and nearly 200 kilometres long.
153
00:20:36,068 --> 00:20:41,120
So inaccessible
that the only way to track it
154
00:20:41,240 --> 00:20:43,538
has been from 600 kilometres up.
155
00:20:47,705 --> 00:20:52,461
Images taken over the year
showed the crack growing,
156
00:20:52,543 --> 00:20:53,635
until eventually...
157
00:20:55,296 --> 00:20:57,799
a vast piece of ice broke free.
158
00:21:00,801 --> 00:21:03,645
Four times the size of Greater London,
159
00:21:03,763 --> 00:21:08,018
it is one of the largest icebergs
on record.
160
00:21:19,612 --> 00:21:21,785
In a remote part of Alberta, Canada...
161
00:21:24,241 --> 00:21:25,993
miles from civilisation...
162
00:21:29,830 --> 00:21:32,379
a strange arced shape...
163
00:21:36,295 --> 00:21:38,047
in the middle of the forest.
164
00:21:40,382 --> 00:21:44,558
This is the world's largest beaver dam.
165
00:21:48,057 --> 00:21:52,153
Satellite records show that it was built
over the last 3O years...
166
00:21:56,357 --> 00:21:59,201
and it's now almost a kilometre long.
167
00:22:01,821 --> 00:22:05,496
No-one knew that the species
was capable of construction
168
00:22:05,616 --> 00:22:07,334
on such a scale.
169
00:22:12,248 --> 00:22:14,250
And in Mozambique, Africa...
170
00:22:19,338 --> 00:22:23,138
a scientist scanning through
satellite images
171
00:22:23,259 --> 00:22:24,727
found a lost world...
172
00:22:31,767 --> 00:22:37,945
an isolated rainforest,
on top of cliffs almost 500 metres high...
173
00:22:40,317 --> 00:22:44,242
completely untouched and unexplored.
174
00:22:49,702 --> 00:22:52,330
Expeditions are now being launched
175
00:22:52,454 --> 00:22:57,426
in the hope of discovering
entirely new species.
176
00:23:10,055 --> 00:23:13,150
But other images are harder to explain.
177
00:23:19,481 --> 00:23:21,904
Lake Baikal, Siberia.
178
00:23:24,945 --> 00:23:27,994
The largest body of fresh water
on the planet.
179
00:23:33,787 --> 00:23:37,587
Its surface
frozen solid for five months of the year.
180
00:23:58,979 --> 00:24:03,655
But satellite images have revealed
something unexpected in the ice.
181
00:24:09,990 --> 00:24:12,709
A huge dark ring.
182
00:24:21,126 --> 00:24:25,006
Broken ice and meltwater
183
00:24:25,130 --> 00:24:28,350
in a circle over four kilometres across.
184
00:24:34,139 --> 00:24:37,518
A number of these rings appear
almost every year...
185
00:24:40,062 --> 00:24:42,611
and in different parts of the lake...
186
00:24:46,485 --> 00:24:49,705
each triggering vast areas of ice
to break apart.
187
00:25:01,250 --> 00:25:02,843
A potential disaster...
188
00:25:04,420 --> 00:25:07,515
for an animal who lives on the ice.
189
00:25:16,015 --> 00:25:17,688
The Baikal seal.
190
00:25:25,899 --> 00:25:28,573
This pup was born in the depths of winter,
191
00:25:28,694 --> 00:25:32,449
spending the first weeks of her life
in and around an ice den.
192
00:25:38,287 --> 00:25:40,881
In the spring, the ice will melt.
193
00:25:49,048 --> 00:25:52,723
She has just two months to prepare
for life in the water.
194
00:26:08,859 --> 00:26:11,328
Moving around on the frozen surface
195
00:26:11,445 --> 00:26:14,369
helps her to shed her soft baby coat.
196
00:26:20,162 --> 00:26:22,381
With claws like ice picks,
197
00:26:22,498 --> 00:26:25,502
pups haul themselves across the ice...
198
00:26:45,020 --> 00:26:47,193
bar the occasional slip-up.
199
00:26:55,656 --> 00:26:59,411
She's developing the muscles needed
to swim and to hunt.
200
00:27:00,953 --> 00:27:03,081
Each day, she grows stronger.
201
00:27:10,337 --> 00:27:12,089
But if an ice ring appears...
202
00:27:13,340 --> 00:27:18,813
a pup, without its adult coat
or full swimming strength,
203
00:27:18,929 --> 00:27:21,307
could become stranded on an ice floe...
204
00:27:22,558 --> 00:27:24,856
or drown in open water.
205
00:27:29,857 --> 00:27:33,862
These melting ice rings
intrigued scientists,
206
00:27:33,986 --> 00:27:35,784
who launched an investigation.
207
00:27:44,288 --> 00:27:46,882
By studying satellite images
208
00:27:46,999 --> 00:27:50,469
and taking measurements
from beneath the ice,
209
00:27:50,586 --> 00:27:54,966
the cause of the rings has been uncovered.
210
00:27:59,428 --> 00:28:02,898
Powerful warm water currents
211
00:28:03,015 --> 00:28:06,064
rising and swirling in circles.
212
00:28:13,901 --> 00:28:16,950
As the ring begins to break apart,
213
00:28:17,070 --> 00:28:21,416
satellites show that the ice
across the rest of the lake is solid.
214
00:28:35,631 --> 00:28:38,555
She has time to prepare
215
00:28:38,675 --> 00:28:40,552
for a life in the water...
216
00:28:42,221 --> 00:28:45,065
once the ice finally melts.
217
00:29:02,574 --> 00:29:04,793
Ours is a blue planet.
218
00:29:09,873 --> 00:29:13,377
From space, we can see
how water defines the landscape.
219
00:29:18,048 --> 00:29:22,144
Ocean tributaries fan out
like branches on a tree
220
00:29:22,261 --> 00:29:25,606
through an island
off the coast of West Africa...
221
00:29:27,140 --> 00:29:32,738
while the veins of the Yukon Delta
flow into the Bering Sea, off Alaska.
222
00:29:38,694 --> 00:29:41,789
We depend so much on water
223
00:29:41,905 --> 00:29:44,078
that we've built our cities around it.
224
00:29:46,410 --> 00:29:47,582
Venice.
225
00:29:51,915 --> 00:29:53,292
London.
226
00:29:59,756 --> 00:30:01,258
Hong Kong.
227
00:30:09,057 --> 00:30:11,310
Wherever there is water on our planet...
228
00:30:15,605 --> 00:30:16,731
there is life.
229
00:30:22,946 --> 00:30:25,825
Botswana, Africa.
230
00:30:30,579 --> 00:30:35,506
In the heart of a desert
is a vast, shimmering fan.
231
00:30:41,423 --> 00:30:45,269
Channels of water have created a delta
232
00:30:45,385 --> 00:30:47,638
that never reaches the ocean...
233
00:30:49,348 --> 00:30:52,318
but disappears into the sand.
234
00:30:56,396 --> 00:30:57,773
The Okavango.
235
00:31:02,235 --> 00:31:06,581
From above, you can see a network
of tracks and paths
236
00:31:06,698 --> 00:31:08,325
running through the wetland.
237
00:31:11,703 --> 00:31:12,875
Crossroads.
238
00:31:15,207 --> 00:31:16,333
Forks in the road.
239
00:31:19,252 --> 00:31:20,378
Roundabouts.
240
00:31:24,758 --> 00:31:28,729
Carefully constructed
by Africa's most unlikely architect...
241
00:31:32,307 --> 00:31:33,604
hiPPOp0tamus.
242
00:31:43,110 --> 00:31:47,286
The delta is home to Botswana's
largest population of hippos.
243
00:31:52,661 --> 00:31:55,335
They wallow in pools to escape the heat.
244
00:32:01,503 --> 00:32:04,598
But they can't escape each other.
245
00:32:16,643 --> 00:32:18,395
Males defend their territory...
246
00:32:21,606 --> 00:32:24,109
while juveniles try to copy them.
247
00:32:30,240 --> 00:32:32,789
There are youngsters underfoot.
248
00:32:42,294 --> 00:32:45,218
And the females have had enough.
249
00:32:47,174 --> 00:32:51,270
They all need just a bit more space.
250
00:33:09,362 --> 00:33:13,083
As the sun begins to set
and the temperature drops...
251
00:33:17,454 --> 00:33:21,584
the hippos leave the pools
to find food.
252
00:33:26,046 --> 00:33:30,017
The best grazing spots
can be more than a kilometre away,
253
00:33:30,133 --> 00:33:31,976
through thick vegetation.
254
00:33:40,352 --> 00:33:43,902
Their routes to feeding grounds
are retraced daily.
255
00:33:51,530 --> 00:33:56,001
Three-tonne bulldozers
keeping the pathways clear.
256
00:34:08,463 --> 00:34:11,012
And as alljourneys originate in a pool,
257
00:34:11,132 --> 00:34:15,262
the hippo tracks
act like release valves...
258
00:34:18,473 --> 00:34:23,525
allowing water and nutrients
to flow deep into the delta.
259
00:34:27,023 --> 00:34:30,493
It's this movement
that creates the channels
260
00:34:30,610 --> 00:34:33,784
that sustain so much life.
261
00:34:49,212 --> 00:34:54,309
These hippo tracks have helped to create
a tangled network of waterways.
262
00:34:58,138 --> 00:35:01,312
Stretching
for over 10,000 square kilometres.
263
00:35:08,440 --> 00:35:11,660
Transforming a desert into an oasis...
264
00:35:13,320 --> 00:35:16,540
in the heart of Southern Africa.
265
00:35:29,336 --> 00:35:32,385
Water isn't the only element needed
for life.
266
00:35:36,760 --> 00:35:37,977
From space,
267
00:35:38,094 --> 00:35:41,098
we can see an extraordinary phenomenon
at work.
268
00:35:42,307 --> 00:35:46,403
A surprising connection
between two distant continents
269
00:35:46,519 --> 00:35:49,523
that supports millions of animal species.
270
00:35:57,405 --> 00:35:59,203
A plume of orange.
271
00:36:02,661 --> 00:36:05,130
Hundreds of kilometres across.
272
00:36:08,541 --> 00:36:09,838
Dust
273
00:36:15,924 --> 00:36:19,929
It comes from here - North Africa.
274
00:36:26,768 --> 00:36:30,614
What looks like a small white scar
in the Sahara desert...
275
00:36:32,107 --> 00:36:35,361
is actually the remains of a vast lake.
276
00:36:43,034 --> 00:36:45,412
Once rich in life,
277
00:36:45,537 --> 00:36:46,834
now a dust bowl.
278
00:36:52,836 --> 00:36:55,214
Winds whipping across the lakebed
279
00:36:55,338 --> 00:36:58,592
lift nutrient-rich Saharan dust
280
00:36:58,717 --> 00:36:59,969
into the air.
281
00:37:10,311 --> 00:37:12,734
By following the dust plume
day and night...
282
00:37:16,860 --> 00:37:21,206
we can see it travel
more than 3,000 kilometres...
283
00:37:27,495 --> 00:37:28,917
over the Atlantic...
284
00:37:43,845 --> 00:37:46,689
to Central and South America...
285
00:37:53,146 --> 00:37:57,026
home to the largest tropical
rainforest in the world.
286
00:38:05,825 --> 00:38:07,919
It rains here almost every day.
287
00:38:14,501 --> 00:38:17,846
But plants need more
than just water to grow.
288
00:38:24,093 --> 00:38:26,516
Nutrient-rich Saharan dust...
289
00:38:28,056 --> 00:38:30,104
carried in the raindrops...
290
00:38:35,271 --> 00:38:36,739
fertilises the soil...
291
00:38:44,405 --> 00:38:45,907
feeding the forest
292
00:38:46,032 --> 00:38:49,252
and helping to sustain
more species of animals...
293
00:38:50,370 --> 00:38:54,341
than anywhere else on Earth.
294
00:39:04,968 --> 00:39:09,348
It was only with satellites
that scientists were able to calculate
295
00:39:09,472 --> 00:39:13,443
that over 27 million tonnes of dust
296
00:39:13,560 --> 00:39:16,029
makes this journey every year.
297
00:39:19,148 --> 00:39:22,698
A gift that has helped
to make these rainforests
298
00:39:22,819 --> 00:39:26,073
some of the most diverse on the planet.
299
00:39:31,661 --> 00:39:35,336
Ancient forces are at work
across our planet.
300
00:39:37,458 --> 00:39:40,587
Their impact etched on the landscape.
301
00:39:53,433 --> 00:39:57,734
A 1,300-kilometre scar
runs through California.
302
00:40:01,858 --> 00:40:03,360
The San Andreas fault.
303
00:40:07,238 --> 00:40:10,242
Created by the shifting of tectonic plates
304
00:40:10,366 --> 00:40:13,586
over the last 3O million years.
305
00:40:21,294 --> 00:40:22,887
The Grand Canyon...
306
00:40:25,298 --> 00:40:28,802
carved by the Colorado River
over millennia.
307
00:40:32,013 --> 00:40:34,141
Now over a kilometre deep.
308
00:40:41,272 --> 00:40:45,527
And Uluru, Ayers Rock, in Australia
309
00:40:45,652 --> 00:40:48,075
has been eroded into an island of stone...
310
00:40:51,449 --> 00:40:54,248
over 500 million years.
311
00:40:59,791 --> 00:41:03,466
But now,
we can see the Earth's surface transform
312
00:41:03,544 --> 00:41:05,888
in almost real time.
313
00:41:10,468 --> 00:41:12,345
In the South Pacific,
314
00:41:12,470 --> 00:41:13,687
two islands...
315
00:41:17,809 --> 00:41:19,482
become one.
316
00:41:28,361 --> 00:41:32,787
New land, formed in a matter of weeks...
317
00:41:34,951 --> 00:41:39,377
by the eruption
of an underwater volcano.
318
00:41:47,296 --> 00:41:53,224
Satellites allow us to monitor
dramatic change over time.
319
00:41:58,558 --> 00:42:00,401
And there's one change
320
00:42:00,518 --> 00:42:04,148
that fundamentally affects
the lives of animals.
321
00:42:05,231 --> 00:42:06,699
The passing seasons.
322
00:42:14,574 --> 00:42:16,952
These are the Himalaya.
323
00:42:19,954 --> 00:42:24,175
A wall of rock
stretching between India and China.
324
00:42:29,881 --> 00:42:31,724
When winter arrives,
325
00:42:31,841 --> 00:42:34,811
the Hengduan range
in the east of the Himalaya
326
00:42:34,927 --> 00:42:36,645
becomes locked in ice.
327
00:42:44,020 --> 00:42:47,115
The temperature rarely rises
above freezing.
328
00:42:52,403 --> 00:42:55,202
Most animals leave the mountains,
329
00:42:55,323 --> 00:42:58,827
choosing lower valleys
to escape the extreme cold.
330
00:43:06,250 --> 00:43:07,547
But not all.
331
00:43:15,510 --> 00:43:18,013
Living 4,000 metres above sea level...
332
00:43:21,224 --> 00:43:25,149
Yunnan snub-nosed monkeys
333
00:43:25,269 --> 00:43:28,614
are the world's highest-living primate.
334
00:43:33,861 --> 00:43:35,534
With dense fur...
335
00:43:37,073 --> 00:43:40,998
and a shortened nose
to avoid frostbite...
336
00:43:42,745 --> 00:43:44,839
they're built for the cold.
337
00:43:50,002 --> 00:43:52,050
This male is a year old.
338
00:43:56,300 --> 00:43:58,302
Without a full adult coat,
339
00:43:58,427 --> 00:44:01,897
he huddles close to his mother
for warmth.
340
00:44:04,725 --> 00:44:06,602
In just a few months,
341
00:44:06,727 --> 00:44:10,402
he'll leave her side and go it alone.
342
00:44:14,610 --> 00:44:17,955
Before then, there are lessons to learn.
343
00:44:23,786 --> 00:44:25,163
The most important...
344
00:44:28,583 --> 00:44:29,755
to find food.
345
00:44:34,255 --> 00:44:37,805
While other animals
head down the mountain to feed,
346
00:44:37,925 --> 00:44:41,850
the male must follow his family...
347
00:44:43,097 --> 00:44:44,269
up...
348
00:44:51,981 --> 00:44:53,824
500 metres...
349
00:44:56,068 --> 00:44:59,242
through some of the hardest terrain
on Earth.
350
00:45:29,143 --> 00:45:31,271
The slopes are shrouded in shadow...
351
00:45:37,068 --> 00:45:40,072
but there is a little sunlight
on the peaks.
352
00:45:41,405 --> 00:45:43,703
It takes the edge off the cold.
353
00:45:55,795 --> 00:45:57,889
But there's only lichen to eat.
354
00:46:10,685 --> 00:46:12,278
It will keep them alive.
355
00:46:13,479 --> 00:46:15,277
But it's far from a feast.
356
00:46:23,948 --> 00:46:27,953
These monkeys endure winter
on these peaks for good reason...
357
00:46:30,913 --> 00:46:32,460
which becomes clear
358
00:46:32,581 --> 00:46:36,711
when you look down from space.
359
00:46:41,090 --> 00:46:44,185
Most of the Himalaya run west to east,
360
00:46:44,302 --> 00:46:47,897
forming a barrier
to tropical air moving north.
361
00:46:51,017 --> 00:46:54,692
But the valleys of the Hengduans
run north to south.
362
00:46:59,191 --> 00:47:01,785
This allows warm, moist air
363
00:47:01,861 --> 00:47:03,989
to funnel up the deep valleys.
364
00:47:12,121 --> 00:47:14,465
By combining satellite images...
365
00:47:18,961 --> 00:47:23,262
we can watch the mountains transform
as spring arrives.
366
00:47:30,306 --> 00:47:34,152
The tropical air increases plant growth,
367
00:47:34,268 --> 00:47:36,441
creating a unique environment.
368
00:47:42,360 --> 00:47:47,207
Amongst the lush green,
bursts of colour.
369
00:48:03,756 --> 00:48:08,478
Rhododendrons bloom in their thousands.
370
00:48:22,066 --> 00:48:23,909
By toughing it out,
371
00:48:24,026 --> 00:48:27,451
the monkeys are rewarded
with a paradise.
372
00:48:34,120 --> 00:48:38,375
A secret kingdom
where they can feed without competition.
373
00:48:46,424 --> 00:48:50,019
Sweet rhododendron nectar is a real treat.
374
00:49:06,610 --> 00:49:08,988
Spring brings new life to the troop.
375
00:49:18,038 --> 00:49:20,211
With the mother's hands full...
376
00:49:22,126 --> 00:49:25,300
it's this male's cue
to start out on his own...
377
00:49:29,341 --> 00:49:31,309
making the most of this new world...
378
00:49:33,679 --> 00:49:36,808
before winter reclaims it again.
379
00:49:49,069 --> 00:49:53,666
While satellites allow us to explore
Earth's most remote landscapes...
380
00:49:57,077 --> 00:49:59,876
we can also see our cities...
381
00:50:07,087 --> 00:50:09,010
find famous landmarks...
382
00:50:17,765 --> 00:50:21,269
and even ourselves.
383
00:50:29,652 --> 00:50:32,826
In Mecca, pilgrims from across the globe
384
00:50:32,947 --> 00:50:36,372
come together to worship during the hajj.
385
00:50:45,209 --> 00:50:47,052
In the UK,
386
00:50:47,169 --> 00:50:51,299
the green fields of Glastonbury transform
387
00:50:51,382 --> 00:50:54,056
into the world's most iconic festival.
388
00:50:59,932 --> 00:51:01,479
In the desert of Nevada...
389
00:51:03,561 --> 00:51:05,563
a crescent is formed
390
00:51:05,688 --> 00:51:08,567
by 50,000 revellers
391
00:51:08,691 --> 00:51:10,409
at Burning Man festival.
392
00:51:16,865 --> 00:51:19,914
And crowds gather in the Vatican
393
00:51:20,035 --> 00:51:22,788
to hear the Pope speak at Easter.
394
00:51:37,219 --> 00:51:39,392
In Central China...
395
00:51:40,848 --> 00:51:43,772
is the small city of Dengfeng.
396
00:51:47,187 --> 00:51:50,066
Amongst the shapes of buildings,
397
00:51:50,190 --> 00:51:52,818
bright red circles.
398
00:51:56,614 --> 00:51:59,367
Shaolin kung fu students.
399
00:52:19,720 --> 00:52:25,318
13-year-old Ching-Yiu Lam
goes to a very different kind of school.
400
00:52:33,817 --> 00:52:36,070
The students here spend their school life
401
00:52:36,195 --> 00:52:40,792
mastering the art of Shaolin kung fu.
402
00:52:46,538 --> 00:52:49,007
Kung fu means hard training.
403
00:52:49,124 --> 00:52:54,130
And to be a champion
takes years of dedication.
404
00:53:07,059 --> 00:53:09,278
As well as normal lessons,
405
00:53:09,395 --> 00:53:12,114
Ching-Yiu spends six hours a day...
406
00:53:13,732 --> 00:53:16,986
six days a week...
407
00:53:17,111 --> 00:53:20,035
learning
multiple martial art disciplines.
408
00:53:33,752 --> 00:53:35,504
And all his training
409
00:53:35,629 --> 00:53:39,850
culminates in a very special performance.
410
00:54:01,280 --> 00:54:04,625
Ching-Yiu is part of a display
so impressive...
411
00:54:10,122 --> 00:54:12,716
that while we film them
on the ground...
412
00:54:14,793 --> 00:54:16,761
at the same moment,
413
00:54:16,879 --> 00:54:19,348
satellites capture the shapes they make.
414
00:54:47,326 --> 00:54:50,546
A series of precise kung fu moves...
415
00:54:54,041 --> 00:54:56,920
creating patterns visible far above.
416
00:55:00,464 --> 00:55:06,312
Thousands of students performing
in perfect synchronicity.
417
00:55:47,427 --> 00:55:51,898
We first went into space
to discover other worlds.
418
00:55:54,476 --> 00:55:56,854
But it's only when we look back
419
00:55:56,979 --> 00:56:02,531
that we realise
just how special our home really is.
420
00:56:10,075 --> 00:56:11,122
Next time...
421
00:56:12,870 --> 00:56:16,249
the view from space
reveals extraordinary landscapes...
422
00:56:19,418 --> 00:56:21,420
covered in strange shapes...
423
00:56:23,797 --> 00:56:25,549
and mysterious patterns.
424
00:56:31,722 --> 00:56:35,477
Water transforms Brazilian sand dunes.
425
00:56:40,564 --> 00:56:43,192
A lake in China disappears...
426
00:56:44,526 --> 00:56:46,278
leading to conflict.
427
00:56:50,449 --> 00:56:53,828
And the twists and turns of the Amazon
428
00:56:53,952 --> 00:56:56,956
are the last hope for vulnerable manatees.
429
00:57:02,336 --> 00:57:05,135
This is our home...
430
00:57:06,340 --> 00:57:09,310
as you've never seen it before.
430
00:57:10,305 --> 00:57:16,915
