This week we're heading to space for a spot of sun, shade and...

0:00:030:00:08

a freaky transforming monkey spider bot.

0:00:080:00:13

We've long fantasised about the possibility

0:00:360:00:38

of life on other planets.

0:00:380:00:41

But it was only in 1995 that we found the first planet

0:00:410:00:44

outside our solar system.

0:00:440:00:49

These exoplanets are hard to find.

0:00:490:00:51

Of course they are, they're relatively tiny.

0:00:510:00:54

And so far they've mainly been detected indirectly,

0:00:540:00:57

either by the incredibly slight dimming of a star's light

0:00:570:01:00

as a planet moves in front of it, or by the wobble of the star

0:01:000:01:04

caused by something orbiting it.

0:01:040:01:09

In the last 20 years we've detected about 2000 exoplanets,

0:01:090:01:13

but we haven't actually seen many at all.

0:01:130:01:17

This is why.

0:01:170:01:19

Well, the planets are very, very faint compared to a star

0:01:190:01:23

and they're very close to a star.

0:01:230:01:30

The kind of planets where we might find life, an Earth-like planet

0:01:300:01:33

orbiting a star would be 10 billion times

0:01:330:01:35

fainter than a star.

0:01:350:01:36

But if you can see the planets, you can start to look for evidence

0:01:360:01:40

of life on their surfaces.

0:01:400:01:41

What you need is something to block out the light of a star.

0:01:410:01:45

What you need is a star shade.

0:01:450:01:51

Due to go into space in the middle of the next decade,

0:01:510:01:55

it is a crazy-sounding thing that can be flown in between a space

0:01:550:02:00

telescope and the star to precisely block out the star's light

0:02:000:02:04

and reveal any planets.

0:02:040:02:08

It'll be a few tens of metres in diameter, and in order to block

0:02:080:02:14

out just the light from that distant star, it'll need to be

0:02:140:02:17

about 40,000 kilometres away from the telescope.

0:02:170:02:22

So you managed to block out the starlight, you see this tiny

0:02:220:02:27

dot which is a planet, what actually will we get from that image?

0:02:270:02:31

What resolution will it be?

0:02:310:02:33

Will it be a few pixels or will we see it in great detail?

0:02:330:02:37

What we'll see is a dot of light completely unresolved.

0:02:370:02:40

Essentially a single pixel.

0:02:400:02:41

So that doesn't sound so interesting, but we'll be able

0:02:410:02:44

first of all to see how far it is from the star,

0:02:440:02:48

and by revisiting it, we'll be able to see what its orbit

0:02:480:02:51

is, so we'll know if it might be a planet that can support life,

0:02:510:02:55

we'll know its separation from the star.

0:02:550:02:58

But more importantly, we'll be able to take that light

0:02:580:03:05

and put a spectrometer on it, disperse it, and look for signatures

0:03:050:03:08

of chemicals on the planet.

0:03:080:03:09

We'll be able to see water, oxygen and carbon dioxide,

0:03:100:03:13

perhaps methane, so signs of life.

0:03:130:03:15

Indications that this might be a planet that supports life.

0:03:150:03:18

And this is not even the maddest part of the scheme.

0:03:180:03:21

See, there's a problem.

0:03:210:03:24

The star shade won't fit in a rocket.

0:03:240:03:26

And that's why a big part of the work being done here

0:03:260:03:29

at Nasa's Jet Propulsion Laboratory in Pasadena, and the beautiful

0:03:290:03:32

solution that they've come up with, is all about fitting the thing

0:03:320:03:36

into a tight space and then unfurling it once in space.

0:03:360:03:41

And the inspiration comes from origami.

0:03:410:03:57

Wow!

0:04:010:04:05

It's really quite impressive.

0:04:050:04:07

At the end you can see how large an area you can fill with such

0:04:070:04:11

a small volume of material.

0:04:110:04:13

But this is only the half of it because you have petals

0:04:130:04:17

which come out here as well?

0:04:170:04:19

Yes, exactly.

0:04:190:04:19

Oh, my goodness.

0:04:190:04:22

This cardboard model is the latest test to make sure the shade

0:04:220:04:25

can unfurl perfectly when it is all alone

0:04:250:04:27

up there in the black.

0:04:270:04:29

The flower shape blocks out the light better than a circle,

0:04:290:04:32

and those outer petals need to be made to an accuracy

0:04:320:04:36

of 50 to 100 microns.

0:04:360:04:39

You're going to point a telescope at a star and then you're

0:04:390:04:42

going to fly this into position to block the light from the star?

0:04:420:04:45

Correct.

0:04:460:04:46

What if you then want to look at another star?

0:04:460:04:49

The telescope moves by a little bit but this thing has got

0:04:490:04:52

to go across the galaxy?

0:04:520:04:53

That's right.

0:04:530:04:54

There are two ways we can do it.

0:04:540:04:58

We could move the entire shade so the star is over

0:04:580:05:00

there and we have the star shade,

0:05:010:05:02

and we have the telescope

0:05:020:05:06

and we can move the star shade to the next target,

0:05:060:05:09

or you can move the telescope to reposition.

0:05:090:05:11

And how long would it take to move?

0:05:110:05:13

It could take from several days to a week or more,

0:05:130:05:16

depending on the next target.

0:05:160:05:17

If I may say, this sounds crazy!

0:05:170:05:19

This sounds like we want to spot some planets,

0:05:190:05:22

what are we going to do?

0:05:220:05:23

We'll put a shade in space and we're going to fire

0:05:230:05:31

We'll put a shade in space and we're going to fly it 40,000 kms

0:05:310:05:34

from the telescope.

0:05:340:05:35

That sounds insane.

0:05:350:05:39

Well, what's really cool about that is there is this insane

0:05:390:05:42

concept of how you're going to fly this

0:05:420:05:44

massive shade so far away, 40,000 kilometres away from the telescope,

0:05:440:05:47

but once you start breaking it down

0:05:470:05:49

into little problems, you start testing and build a petal,

0:05:490:05:52

you build the truss, you build the shield,

0:05:520:05:54

you realise piece by piece what engineering needs to go

0:05:540:05:56

in to that problem to solve it.

0:05:570:05:58

So we just break it down into little problems that we can solve

0:05:590:06:02

in a piecewise fashion.

0:06:020:06:03

And isn't that a great motto for life?

0:06:030:06:05

Take an impossible problem and break it down into more possible chunks.

0:06:050:06:08

I love the fact that at JPL you can just wander into a random room

0:06:080:06:13

and it is called something like the Extreme Terrain Mobility lab.

0:06:130:06:15

That's what they're doing here.

0:06:150:06:17

They're making robots to cope with extreme terrain.

0:06:170:06:19

This is Axel which is a robot with a pair of wheels that can be

0:06:190:06:23

lowered down cliffs.

0:06:230:06:24

And this is Fido and Athena.

0:06:240:06:26

These are the prototype is for the Mars rovers

0:06:260:06:28

Spirit and Opportunity.

0:06:280:06:31

Of course the point about robots is they can do things that humans

0:06:310:06:35

might want to do but in places that humans can't go.

0:06:350:06:38

All of these have fairly familiar designs, wheels here,

0:06:380:06:40

some robots have legs.

0:06:400:06:43

But Kate Russell has found one that looks like nothing

0:06:430:06:45

I have ever seen before.

0:06:450:06:48

In 2012 the world watched with baited breath as Nasa deployed

0:06:500:06:53

a rover on the surface of Mars using a sky crane.

0:06:530:06:59

This kind of science is incredibly expensive.

0:06:590:07:04

The rover weighed 900 kilograms, as much as a full grown giraffe.

0:07:040:07:09

With the equipment required to land it gently, it had to be able to take

0:07:090:07:13

the weight of 32 giraffes.

0:07:130:07:17

Total cost, $2.5 billion.

0:07:170:07:22

It would have been much cheaper if Curiosity was lightweight,

0:07:220:07:25

came flat-packed and was sturdy enough just to be dropped

0:07:250:07:27

on the red planet's surface.

0:07:270:07:37

Meet Super Ball, a tensgrity robot in development in Nasa Ames.

0:07:370:07:40

This lightweight sphere-like matrix can be packed down flat,

0:07:400:07:43

taking up minimal space in a rocket and vastly reducing launch costs.

0:07:440:07:48

Because of the unique structure of this robot and the fact

0:07:480:07:52

that it can deform and reform itself and take massive impacts,

0:07:520:07:56

eventually Nasa will be able to literally throw it at the surface

0:07:560:07:59

of a planet and its scientific payload in the middle

0:07:590:08:02

will be protected.

0:08:020:08:04

It's bouncy.

0:08:040:08:06

Once deployed, Super Ball can handle much rougher terrains then a rover,

0:08:060:08:10

riding over obstacles and up and down hills.

0:08:100:08:16

Tendon wires connecting the struts spool in and out creating momentum,

0:08:160:08:21

in much the same way as flexing your muscles

0:08:210:08:24

moves your limbs.

0:08:240:08:25

If it bumps into anything solid, it will just bounce back.

0:08:250:08:28

It should even be able to survive falling off a cliff.

0:08:280:08:32

The next step for Super Ball is to redesign the robot such

0:08:320:08:35

that it can actually survive at least a one-storey drop.

0:08:350:08:38

You can expect to see a system like this on an actual Nasa mission

0:08:380:08:42

probably in 15 or 20 years' time.

0:08:420:08:46

Over at JPL, they are working on limbed robots.

0:08:460:08:51

Its research spawned from the DARPA Robotics Challenge where teams

0:08:510:08:54

competed to create highly mobile and dextrous robots that can move,

0:08:540:08:58

explore and build things without human intervention.

0:08:580:09:04

One of the great things about the simian body plan is that

0:09:040:09:08

all of our limbs can be used for either mobility or manipulation.

0:09:080:09:11

And so, if we are putting things together, you could certainly

0:09:110:09:14

imagine hanging on with a couple of them and doing the manipulation

0:09:140:09:18

to assemble things together with others, and that makes

0:09:180:09:21

for a very robust way of putting things together,

0:09:210:09:23

in an environment like zero G where you don't want to float off.

0:09:240:09:27

The plan for King Louis is to be sent into space to build stuff

0:09:270:09:31

with visual codes a bit like QR codes to guide it.

0:09:310:09:34

We have a structured environment.

0:09:340:09:35

We know what we are putting together so we put signposts

0:09:350:09:39

onto all the bits and pieces of the structure we are putting

0:09:390:09:44

together that tell the robot a few things.

0:09:440:09:46

Most importantly, it tells the robot where those things

0:09:460:09:49

it is manipulating are in space, literally and figuratively,

0:09:490:09:51

so it can align itself better.

0:09:520:09:56

The codes will also include construction information

0:09:560:09:58

like which bits go together and how much torque to apply to a bolt.

0:09:590:10:03

This will allow robots to work autonomously in teams,

0:10:030:10:06

building space stations or planetary habitats faster

0:10:060:10:10

and more economically than previously possible.

0:10:100:10:14

But Nasa hasn't completely given up on our four-wheeled space helpers.

0:10:140:10:19

Here we've tried to develop new kinds of robots

0:10:190:10:22

for future space exploration.

0:10:220:10:24

This robot, for example, is called K-Rex.

0:10:240:10:27

It's one of our main research robots that we develop and test here

0:10:270:10:30

in the robotscape at Nasa Ames.

0:10:300:10:36

This is a large play area for robots, a proving ground

0:10:360:10:39

that we use to really try to develop things like navigation

0:10:390:10:42

or do the mission simulations.

0:10:420:10:45

One of the biggest problems with space travel is getting

0:10:450:10:48

stuff of our planet.

0:10:480:10:51

It requires an incredible amount of fuel to break

0:10:510:10:54

through the atmosphere.

0:10:540:10:55

So K-Rex's current job is to look at ways to collect useful resources

0:10:550:10:59

once we are already out in space.

0:10:590:11:01

Can we go to the moon, find water and use it for oxygen

0:11:010:11:04

and hydrogen to make fuel and go other places beyond the moon?

0:11:040:11:08

For you, what is the most exciting sort of new development

0:11:080:11:11

that is on the horizon?

0:11:120:11:13

For a long time now we had robots do exploration.

0:11:130:11:15

We have rovers on Mars, they are still functioning today.

0:11:160:11:18

We have humans in space on the International Space Station,

0:11:180:11:21

and in the future I think what we're going to see more of is

0:11:210:11:25

really human-robot teams.

0:11:250:11:26

Robots might be working ahead of humans, they might be working

0:11:260:11:29

following up after humans, they might be side-by-side or

0:11:290:11:32

perhaps just in support of humans.

0:11:320:11:33

In any case, what we're going to have is a future of robots

0:11:330:11:37

and humans working together.

0:11:370:11:38

So, the biggest question perhaps of the day for me,

0:11:380:11:41

can I drive K-Rex?

0:11:410:11:42

Definitely.

0:11:420:11:42

Let's have you do that.

0:11:420:11:44

Yes!

0:11:440:11:46

Now lots of you think we Click reporters have the best jobs

0:11:460:11:50

in the world, but after spending a day at the roverscape testing

0:11:500:11:53

ground, I think there is another contender for that title.

0:11:530:11:59

Hello and welcome to the Week in Tech.

0:12:030:12:06

It was the week that in the US, after much speculation,

0:12:060:12:09

Facebook head honcho Mark Zuckerberg denied he wants to run for president

0:12:090:12:12

of the United States.

0:12:120:12:15

Not everyone wants to run the world, it seems, just the bits

0:12:150:12:18

related to social media.

0:12:180:12:22

Plus, help could be at hand for forgetful Apple Airpod owners.

0:12:220:12:27

Apple has created a find Airpods feature for its wireless earbuds.

0:12:270:12:32

It works in the same way as the Find My Phone feature.

0:12:320:12:35

No word yet though on how much rummaging down the back

0:12:350:12:38

of the sofa it will lead to.

0:12:380:12:40

Plus, authorities in Dubai showed off a new way of fighting fires.

0:12:400:12:43

All with the help of a jet-ski for traffic avoiding rapid

0:12:430:12:46

response and a jet pack for some elevated extinguishing.

0:12:460:12:51

Water pressure kicks the firefighter airborne allowing them to target

0:12:510:12:54

difficult to reach fires near waterways

0:12:540:12:58

and then hose them down.

0:12:580:13:00

Next, never get off the boat.

0:13:000:13:04

Legendary movie director Francis Ford Coppola has

0:13:040:13:06

thrown his support behind a video game version of his Vietnam war

0:13:060:13:09

epic Apocalypse Now.

0:13:090:13:11

It is going to be survival horror and it is going to be

0:13:110:13:15

financed via crowdfunding.

0:13:150:13:19

And finally, fashion conscious astronauts have had to make do

0:13:190:13:24

with any colour space suit they like as long as it is in white.

0:13:250:13:30

Not any more.

0:13:300:13:31

Nasa and Boeing have revealed details of the new

0:13:310:13:34

upgraded blue space suit.

0:13:340:13:35

These are lighter and easier to move in.

0:13:350:13:37

Personally, I'd prefer pinstriped.

0:13:370:13:43

Up on the International Space Station, resources are pretty tight.

0:13:450:13:50

But while food and water do need to be delivered as take-out,

0:13:500:13:54

you might think that power at least might be plentiful.

0:13:540:13:59

But over their lifetime, the International Space Station's

0:13:590:14:14

solar arrays degrade and produce less power.

0:14:140:14:15

And as our space aspirations grow, we could do with more and more

0:14:160:14:19

power anyway from bigger and bigger panels.

0:14:190:14:21

That's a bit of a problem.

0:14:210:14:23

To give you an idea of how much power the ISS needs,

0:14:230:14:26

it has eight solar arrays.

0:14:260:14:27

Each one is as long and as tall...

0:14:270:14:29

As this room.

0:14:290:14:35

To fit something this huge into a rocket's payload,

0:14:350:14:39

as we discovered with the star shade, you have to fold it up.

0:14:390:14:43

The problem is each part of the solar array

0:14:430:14:48

is mounted on a thick protective aluminium backing.

0:14:480:14:51

The more you fold it to reduce the length,

0:14:510:14:56

the more you increase the thickness.

0:14:560:14:58

Bit here at Lockheed Martin in Palo Alto, Wahid Azizpor

0:14:580:15:00

is working on a solution.

0:15:000:15:03

I am constantly surprised by anything that goes into space,

0:15:030:15:05

about how light it is.

0:15:050:15:07

It looks quite thick but it's so light.

0:15:070:15:09

It has to be.

0:15:090:15:10

It costs a lot of money to launch one of these in space

0:15:100:15:14

so it has to be light.

0:15:140:15:15

Why did you need that?

0:15:150:15:17

To make sure the cells did not crack when you're launching in space.

0:15:170:15:20

It's really violent when it goes in space and on a rocket itself.

0:15:200:15:24

So it's not when it's in space, it's actually the launching

0:15:240:15:27

and I guess the unfurling that can damage these things?

0:15:270:15:29

That can damage the cells.

0:15:290:15:31

But this is not good enough for you!

0:15:310:15:33

This is the thickness of a normal solar array and you are now

0:15:330:15:36

making them that thick.

0:15:360:15:38

It's a substance called kapton and it will replace that

0:15:380:15:40

thick aluminium support.

0:15:400:15:46

It feels like a bit of plastic.

0:15:460:15:48

So what does this mean for stuff that goes into space now,

0:15:480:15:55

whether it is space travel or satellites?

0:15:550:16:00

What does this mean?

0:16:000:16:05

You can put a lot more power, a lot more stuff in space

0:16:050:16:08

in a small area itself, so you don't need all these things.

0:16:080:16:12

All you can put is the kapton so if you want double the power,

0:16:120:16:15

all you need to do is double the amount of that material, kapton,

0:16:150:16:19

which adds another inch to it and it doubles the amount

0:16:190:16:22

of power you need.

0:16:220:16:23

Only a few of us will, of course, ever get into space,

0:16:230:16:26

but for the next best thing, why not try it in VR?

0:16:260:16:29

Here's Lara Lewington.

0:16:290:16:30

I've had some really engaging virtual reality experiences.

0:16:330:16:37

One of them simply set in an office, but it seems if you are entering

0:16:370:16:41

at VR world, you might as well go somewhere really

0:16:410:16:44

exciting, like space.

0:16:440:16:45

That's where Home: A VR Spacewalk takes you.

0:16:450:16:54

Inspired by Nasa's training programme, it aims to bring

0:16:540:16:56

a mission in space to the masses.

0:16:560:16:59

After getting used to your new surroundings, you undertake

0:16:590:17:02

an emergency mission.

0:17:020:17:10

Whilst enjoying views of Earth from afar, a friendly hand

0:17:100:17:13

from a fellow astronaut helps to get you on your way.

0:17:130:17:16

Ah, I can hold a hand.

0:17:160:17:18

I feel a strange sense of safety there is another astronaut here.

0:17:180:17:21

The BBC commissioned the experience last year,

0:17:210:17:24

as its first steps into the world of virtual reality content.

0:17:240:17:28

We've taken all the storytelling power of the BBC and applied that

0:17:290:17:32

behind it, so there's a great script, a great narrative and then

0:17:320:17:35

we've looked at all the cutting edge explorations people are doing around

0:17:350:17:38

VR, in terms of bio-monitoring, haptic feedback etc etc and trying

0:17:380:17:41

to bring that into it as a massive piece of learning really.

0:17:410:17:49

My preview here on the HTC Vive saw it set up with a chair providing

0:17:490:17:54

haptic feedback and a heart rate monitor which resulted

0:17:540:18:01

in my being sent back to base if readings went too high.

0:18:010:18:04

But apparently I'm very calm in space.

0:18:040:18:06

In March it will be released for Vive on Steam as well as Oculus.

0:18:060:18:10

Wow, this is incredible.

0:18:100:18:12

I'm now looking at Vancouver apparently.

0:18:120:18:16

Some artistic license was of course needed like making tasks shorter

0:18:160:18:19

so they wouldn't get boring, but aside from creating the pictures

0:18:190:18:22

and story telling a project as bold as this needs,

0:18:220:18:27

there were the usual challenges faced by those producing VR content.

0:18:270:18:32

In 360 video and virtual reality, locomotion is one

0:18:320:18:34

of the biggest problems.

0:18:340:18:36

If you move someone without them having made a conscious

0:18:360:18:39

decision to be moved, it can be very disorientating.

0:18:390:18:41

To get around those problems in this particular environment of zero

0:18:410:18:44

gravity on the outside of the space station, we built a system

0:18:440:18:47

where you move yourself by grabbing handles,

0:18:470:18:49

so every single movement of yourself in the environment is always user

0:18:490:18:53

initiated and as granular, slow or as fast as you

0:18:530:18:55

are comfortable with.

0:18:550:19:01

Oh, goodness!

0:19:010:19:08

I feel most disorientated!

0:19:080:19:11

Wow, the depth of it I think was the thing

0:19:110:19:15

that was most surprising.

0:19:150:19:17

You really got a sense of being up high, seeing things

0:19:170:19:20

really, really far away.

0:19:200:19:21

It took awhile to get grips with what I was meant to be doing,

0:19:210:19:25

but just the fact that I was moving around within space

0:19:250:19:28

was quite incredible.

0:19:280:19:30

Whilst it wasn't possible to create a sense of weightlessness,

0:19:300:19:33

the pictures were amazing, but obviously, I can't vouch for how

0:19:330:19:37

true to life they are.

0:19:380:19:45

It is essential to life on Earth, but the sun is a fearsome beast

0:19:460:19:51

and cares is not one jot for the way that we've chosen to live.

0:19:510:19:57

Seen up close, this seemingly uniform sphere of light reveals

0:19:570:20:01

itself as a churning, raging ball of fire.

0:20:010:20:09

Every so often, the surface erupts, flinging huge amounts

0:20:090:20:11

of particles into space, in a phenomenon known

0:20:110:20:13

as a coronal mass ejection.

0:20:130:20:18

So this is a coronal mass ejection in close-up?

0:20:180:20:21

This is what astrophysics does.

0:20:210:20:22

This is how we figure out what gases are in there,

0:20:220:20:26

how fast they move, how hot they are, how dense they are.

0:20:260:20:29

Have we ever been hit by one of those?

0:20:290:20:32

The Earth has been hit by one of those, yes, many times.

0:20:320:20:35

Many times?

0:20:350:20:37

That's not game over when we are hit by something because it

0:20:370:20:40

looks quite final to me!

0:20:400:20:41

It is huge.

0:20:410:20:42

The Earth is about this size.

0:20:420:20:45

No, we get hit very readily, every 11 years the sun goes

0:20:450:20:51

through a cycle where the sun's domestic field gets very active

0:20:510:20:54

and then we get a lot of these.

0:20:540:20:56

This is what we call space winter.

0:20:560:20:58

Which I guess makes Bart De Pontieu a space weatherman.

0:20:580:21:02

He is in charge of Iris, a satellite launched three years ago

0:21:020:21:11

which looks at small parts of the sun in great detail.

0:21:110:21:16

His job is to use what he sees to create solar computer

0:21:160:21:19

simulations, which may unlock its mysteries,

0:21:190:21:21

and may help us to understand where the particular coronal mass

0:21:210:21:24

ejections will affect us on Earth.

0:21:240:21:26

You can see in this movie when that eruption happens.

0:21:260:21:28

You see all that snow on the image.

0:21:280:21:31

Those are the energetic particles of the sun that hit our detectors,

0:21:310:21:34

our CCDs and they leave charges in there.

0:21:340:21:36

These energetic particles in fact, not just the CCDs, but they can

0:21:360:21:41

impact the computers on-board satellites, and that means

0:21:410:21:44

the satellites can flip a bit essentially and screw up the whole

0:21:450:21:48

operation of the satellite.

0:21:480:21:51

Satellites have gotten lost as a result.

0:21:510:21:54

And so when these things happen, you can go in safe mode.

0:21:540:21:57

If you can predict them properly, you can go in safe mode.

0:21:580:22:01

Many of these storms can be geo-affective and changing

0:22:010:22:03

the environment around Earth, they can lead to power

0:22:030:22:06

grids getting overloaded and transformers blowing up.

0:22:060:22:12

And so you could actually cycle down usage on your power grid if you knew

0:22:120:22:16

that something like this was happening, or you could tell

0:22:160:22:19

your troops that your satellite communications might be disturbed

0:22:190:22:21

because the atmosphere is disturbed that day.

0:22:210:22:23

Iris isn't the only space telescope to come out of Lockheed Martin

0:22:230:22:27

here in California.

0:22:270:22:31

A new one was launched in 2016, and before the launch we got a sneak

0:22:310:22:35

preview of how they were testing it.

0:22:350:22:37

Using this.

0:22:370:22:38

Welcome to the Heliostat.

0:22:380:22:42

The point of this thing is to bring what's up

0:22:420:22:44

there down to the labs below, so if I lean down this

0:22:450:22:48

tube, you can see me.

0:22:480:22:49

Hello, there.

0:22:490:22:51

Of course, you don't really want to see me or just the blue sky.

0:22:510:22:55

What you actually want to see is...

0:22:550:22:57

Down here, the sun's image is bounced around and fired

0:22:570:22:59

into the clean room containing the new satellites,

0:23:000:23:02

which are so small, they can fit four of them

0:23:020:23:05

into a relatively tiny space.

0:23:050:23:07

The next generation of solar monitoring telescope

0:23:070:23:09

is happening there.

0:23:090:23:10

The solar ultraviolet image will watch the sun

0:23:100:23:13

in extreme ultraviolet.

0:23:130:23:20

It should be able to provide early warnings of heavy space weather

0:23:200:23:25

caused by solar flares and coronal mass injections, and will ultimately

0:23:250:23:28

help us to unlock the secrets of our nearest star.

0:23:280:23:35

Something that is no longer just for scientific interest,

0:23:350:23:38

but will protect a society that is increasingly dependent

0:23:380:23:40

on technology as well.

0:23:400:23:43

This is the example of one of the simulations from

0:23:430:23:46

the University of Oslo in Norway.

0:23:460:23:49

Isn't that sexy?!

0:23:490:23:49

We really need these models to understand what we're seeing

0:23:500:23:52

and how we could possibly predict things like this.

0:23:520:23:55

Tell me you've got that as your desktop wallpaper

0:23:550:23:58

because I want a copy of that!

0:23:580:23:59

I do!

0:23:590:24:01

LAUGHTER

0:24:010:24:04

Hello there.

0:24:270:24:28

The weather is on the change as we head through the course

0:24:290:24:32

of the weekend.

0:24:320:24:33
