From space...

The view of our planet

..is breathtaking.

Satellites orbiting the Earth...

..can now look down on it...

..in absolutely
extraordinary detail.

Using cameras on the ground...

..in the air...

..and in space...

..we can tell the story of life on
Earth from a brand-new perspective.

At a time when the Earth's surface
is changing faster

than at any point
in human history...

..we can see just what
impact we're having.

In this episode...

..satellites uncover previously
unknown colonies of penguins...

PENGUIN CHIRPS

..reveal mysterious ice rings that
could put seal pups in danger...

..and make surprising discoveries
in Earth's most remote landscapes.

Behind every image...

..there's a story.

This is our home...

..as we've never seen it before.

CROWD CHANTING

At any given moment, over a thousand
satellites are orbiting the Earth.

Some are capturing images across
the planet's surface so detailed...

..that we can now see individual
animals from space...

..while simultaneously
following them on the ground.

Kenya, East Africa.

The green of a river bank.

Look closely, and grey
bodies are just visible.

A family of elephants.

ELEPHANT TRUMPETS

They have a new calf...

..just over a week old.

ELEPHANT RUMBLES

ELEPHANT SQUEAKS

At around 100kg
and growing fast,

she needs to drink some
12 litres of milk a day.

But her mother is struggling
to provide it for her.

She hasn't fed properly in weeks.

In fact,
the whole herd is in trouble.

ELEPHANT TRUMPETS

And from space...

..it's clear why.

At this time of year, the family
is usually found 10km north,

in the relative safety of
Samburu National Reserve.

But satellite images reveal
that all is not well here.

The ground is deep orange.

Barely any signs of water...

..or green spots of vegetation.

Samburu is in the grip
of a vicious drought.

Northern Kenya has been struck hard
by the planet's changing climate.

INSECTS BUZZ AND CHIRRUP

This year has seen 25% less rain
than the average.

The dry season has been extreme.

Animals are starving.

FLIES BUZZ

A desperate search for food
has forced the family

out of the safety of the reserve...

..to a few small patches of green,

dangerously close to
a busy main road.

ELEPHANT RUMBLES

Scrubby vegetation provides
a little to eat.

But here, the family could
be a target for poachers.

On the ground,
their situation is desperate.

But with cameras in space,
we can see what the elephants can't.

From a satellite taking an image of
the whole Earth every 15 minutes...

..we can track weather patterns.

Over East Africa...

..clouds are building.

Rain is just six days away.

The calf is worn out.

But her mother will not
let her rest.

ELEPHANT HUFFS

It's not safe to be so close
to a busy road.

They need to move on.

But she's too tired.

THUNDER RUMBLES

THUNDER RUMBLES

ELEPHANT GRUNTS

This is the first rain
she's ever experienced...

ELEPHANT SQUEAKS

..and it's hard
to get to grips with.

Her mother encourages her
to her feet.

She wants her baby out of
this dangerous place.

Samburu is transforming.

Elephants, scattered by the drought,
are now returning to the reserve.

And our family is with them.

Overnight, one of the other females
has given birth.

The rain means the best start
for a new generation,

for this vulnerable species.

And it's not just elephants
we can see from space.

Satellite cameras are finding
animals across the globe.

The dunes of Namibia,
Southern Africa.

Tiny, dark spots line
the edge of the surf.

Each one is a Cape fur seal...

..in a colony
several thousand strong.

Over the East African Plains
of the Serengeti...

..scientists monitor the size
of wildebeest herds

on their annual migration.

From 600km above Baja, Mexico...

..we can see grey whales

beneath the water...

..arriving here to give birth.

This new technology is now helping
wildlife conservation

in the most inaccessible places.

Antarctica.

A continent so hostile and remote...

..that studying life here is
incredibly challenging.

But now,
satellites allow us to access

every square kilometre
of its surface.

And this has led
to an extraordinary discovery.

Brown patches,
dotted across the ice.

Seemingly out of place...

..but they are vital clues,
helping us to find

one of our most iconic species.

SQUAWKING

Emperor penguins.

This colony is full of new life.

Hatched just a month before,

the chicks consume pre-digested
fish and krill,

brought to them by their parents.

But the results of this diet
can be messy.

Over 10,000 birds create

a vast amount...

of poo.

A problem for the colony.

At -20, all the water
is frozen solid.

With nothing to drink,

Penguins eat the snow beneath
their feet...

..which is becoming rather
unappealing.

They need to find fresh snow.

The youngest chicks,

who aren't yet able to keep
themselves warm,

are carried on their parents' feet.

Others should be walking by now.

As each penguin moves to
find clean snow...

..the colony slowly works its way
across the ice...

..leaving a trail behind them.

Over weeks, the patches spread.

From space, a penguin colony would
be difficult to spot

in this vast sea of white.

But the marks they leave behind
stand out.

And now that scientists know
what to look for,

they are finding more colonies.

So far, 26 new colonies have
been discovered...

..doubling the known
global population of the species.

A discovery at a crucial time.

It is predicted that the sea ice
on which the penguins breed

will recede, due to climate change.

And as a consequence,
20% of Emperor Penguins

could disappear in the next century.

From satellite, scientists are now
monitoring these colonies

as they face an uncertain future.

The view from space is allowing us
to make scientific breakthroughs

in the most remote places
on the planet.

In 2017, cameras captured a crack in
the Antarctic ice shelf...

..450 metres wide...

..and nearly 200km long.

So inaccessible,
that the only way to track it

has been from 600km up.

Images taken over the year showed
the crack growing,

until eventually, a vast piece
of ice broke free.

Four times the size of
Greater London,

it is one of the largest
icebergs on record.

In a remote part of Alberta,
Canada...

..miles from civilisation...

..a strange, arced shape...

..in the middle of the forest.

This is the world's largest
beaver dam.

Satellite records show that it was
built over the last 30 years.

And it's now almost
a kilometre long.

No-one knew that the species was
capable of construction

on such a scale.

And in Mozambique, Africa...

..a scientist scanning through
satellite images

found a lost world.

An isolated rainforest, on top of
cliffs almost 500 metres high.

Completely untouched and unexplored.

Expeditions are now being launched,

in the hope of discovering
entirely new species.

But other images are harder
to explain.

Lake Baikal, Siberia.

The largest body of fresh water
on the planet...

..its surface frozen solid
for five months of the year.

But satellite images have revealed
something unexpected in the ice...

..a huge, dark ring.

Broken ice and meltwater

in a circle, over 4km across.

A number of these rings appear
almost every year...

..and in different parts
of the lake...

..each triggering vast areas of ice
to break apart.

A potential disaster...

..for an animal who lives
on the ice.

The Baikal seal.

This pup was born in the
depths of winter,

spending the first weeks of her life
in and around an ice den.

In the spring, the ice will melt.

She has just two months to prepare
for life in the water.

Moving around on the frozen surface

helps her to shed her soft
baby coat.

With claws like ice picks, pups haul
themselves across the ice...

..bar the occasional slip-up.

She's developing the muscles needed
to swim and to hunt.

Each day, she grows stronger.

But if an ice ring appears...

..a pup without its adult coat
or full swimming strength

could become stranded
on an ice floe

or drown in open water.

These melting ice rings
intrigued scientists,

who launched an investigation.

By studying satellite images
and taking measurements

from beneath the ice, the cause of
the rings has been uncovered.

Powerful warm water currents,

rising and swirling in circles.

As the ring begins to break apart,

satellites show that the ice across
the rest of the lake is solid.

She has time to prepare for
a life in the water...

..once the ice finally melts.

Ours is a blue planet.

From space, we can see
how water defines the landscape.

Ocean tributaries fan out like
branches on a tree,

through an island
off the coast of West Africa...

..while the veins of the Yukon Delta
flow into the Bering Sea,

off Alaska.

We depend so much on water
that we built our cities around it.

Venice.

London.

Hong Kong.

Wherever there is water
on our planet...

..there is life.

Botswana, Africa.

In the heart of the desert is
a vast, shimmering fan.

Channels of water have created
a delta,

that never reaches the ocean,
but disappears into the sand.

The Okavango.

From above, you can see a network
of tracks and paths,

running through the wetland.

Crossroads...

..forks in the road...

..roundabouts.

Carefully constructed by Africa's
most unlikely architect...

..hippopotamus.

The delta is home to Botswana's
largest population of hippos.

They wallow in pools
to escape the heat.

But they can't escape each other.

Males defend their territory...

..while juveniles try to copy them.

There are youngsters underfoot.

GRUNTING

And the females have had enough.

They all need just a bit more space.

As the sun begins to set
and the temperature drops...

..the hippos leave the pools
to find food.

The best grazing spots can be more
than a kilometre away,

through thick vegetation.

Their routes to feeding grounds
are retraced daily.

Three-tonne bulldozers,
keeping the pathways clear.

And, as all journeys originate
in the pool,

the hippo tracks act like
release valves...

..allowing water and nutrients to
flow deep into the delta.

It's this movement that creates
the channels

that sustain so much life.

These hippo tracks have helped
to create

a tangled network of waterways...

..stretching for over 10,000
square kilometres...

..transforming a desert
into an oasis

in the heart of Southern Africa.

Water isn't the only element
needed for life.

From space, we can see an
extraordinary phenomenon at work.

A surprising connection between
two distant continents,

that supports millions
of animal species.

A plume of orange...

..hundreds of kilometres across.

Dust.

It comes from here - North Africa.

What looks like a small, white scar
in the Sahara desert

is actually the remains
of a vast lake.

Once rich in life, now a dust bowl.

Winds whipping across the lake bed

lift nutrient-rich Saharan dust
into the air.

By following the dust plume
day and night...

..we can see it travel
more than 3,000km...

..over the Atlantic...

..to Central and South America...

..home to the largest tropical
rainforest in the world.

THUNDER RUMBLES

It rains here almost every day.

But plants need more than
just water to grow.

Nutrient-rich Saharan dust,

carried in the raindrops...

..fertilises the soil...

..feeding the forest and helping to
sustain more species of animals

than anywhere else on Earth.

It was only with satellites that
scientists were able to calculate

that over 27,000,000 tonnes
of dust

makes this journey every year.

A gift that has helped to make
these rainforests

some of the most diverse
on the planet.

Ancient forces are at work
across our planet.

Their impact etched
on the landscape.

A 1,300km scar runs
through California.

The San Andreas Fault.

Created by the shifting
of tectonic plates

over the last 30 million years.

The Grand Canyon.

Carved by the Colorado River,
over millennia...

..now over a kilometre deep.

And Uluru, Ayres Rock, in Australia

has been eroded into an
island of stone...

..over 500 million years.

But now, we can see the
Earth's surface transform

in almost real-time.

In the South Pacific,
two islands...

..become one.

New land, formed in a
matter of weeks...

..by the eruption
of an underwater volcano.

Satellites allow us to monitor
dramatic change over time.

And there's one change

that fundamentally affects the
lives of animals -

the passing seasons.

These are the Himalaya...

..a wall of rock, stretching
between India and China.

When winter arrives,

the Hengduan range in the East
of the Himalaya

becomes locked in ice.

The temperature rarely rises
above freezing.

Most animals leave the mountains,

choosing lower valleys

to escape the extreme cold.

But not all.

Living 4,000 metres above
sea level...

..Yunnan snub-nosed monkeys...

..are the world's highest
living primate.

With dense fur...

..and a shortened nose
to avoid frostbite...

..they're built for the cold.

This male is a year old.

Without a full adult coat,

he huddles close to his mother
for warmth.

In just a few months,
he'll leave her side

and go it alone.

Before then,
there are lessons to learn.

The most important...

..to find food.

While other animals head
down the mountain to feed,

the male must follow his
family up...

..500 metres...

..through some of the hardest
terrain on Earth.

The slopes are shrouded in shadow.

But there is a little sunlight
on the peaks.

It takes the edge off the cold.

But there's only lichen to eat.

It will keep them
alive, but it's far from a feast.

These monkeys endure winter on these
peaks for good reason...

..which becomes clear
when you look down from space.

Most of the Himalaya
run west to east,

forming a barrier to tropical air
moving north.

But the valleys of the Hengduans
run north to south.

This allows warm, moist air
to funnel up the deep valleys.

By combining satellite images...

..we can watch the mountains
transform, as spring arrives.

The tropical air increases
plant growth,

creating a unique environment.

Amongst the lush greens,
bursts of colour.

Rhododendrons bloom in
their thousands.

By toughing it out,

the monkeys are rewarded
with a paradise.

A secret kingdom, where they can
feed without competition.

Sweet rhododendron nectar
is a real treat.

Spring brings new life to the troop.

With the mothers hands full...

..it's this male's cue to
start out on his own.

Making the most of this new world...

..before winter reclaims it again.

While satellites allow us

to explore Earth's most remote
landscapes...

..we can also see our cities.

Find famous landmarks...

..and even ourselves.

In Mecca, pilgrims from across
the globe come together

to worship during the Hajj.

In the UK, the green fields
of Glastonbury

transform into the world's
most iconic festival.

In the desert of Nevada...

..a crescent is formed by 50,000
revellers at Burning Man festival.

And crowds gather in the Vatican
to hear the Pope speak at Easter.

In central China is the small
city of Dengfeng.

Amongst the shapes of buildings,
bright red circles.

Shaolin Kung Fu students.

13-year-old Xing Yu La goes to a
very different kind of school.

THEY SHOUT OUT

The students here spend
their school life

mastering the art of
Shaolin Kung Fu.

SHOUTING

Kung fu means hard training,

and to be a champion takes
years of dedication.

As well as normal lessons, Xing Yu
spends six hours a day...

..six days a week...

..learning multiple
martial art disciplines.

Ah!

Ah!

And all his training

culminates in a very special
performance.

Xing Yu is part of a display
so impressive...

Ah!

..that while we film them
on the ground...

..at the same moment,

satellites capture the shapes
they make.

THEY SHOUT TOGETHER

A series of precise kung fu moves...

..creating patterns visible
far above.

Thousands of students performing
in perfect synchronicity.

We first went into space to
discover other worlds.

But it's only when we look back
that we realise

just how special our home really is.

Next time...

..the view from space reveals
extraordinary landscapes...

..covered in strange shapes...

..and mysterious patterns.

Water transforms Brazilian
sand dunes.

A lake in China disappears...

..leading to conflict.

And the twists and turns
of the Amazon

are the last hope
for vulnerable manatees.

This is our home...

..as you've never seen it before.
