This is bbc news. The headlines president trumps restrictions on refugees and people from seven mainly muslim countries entering the United States is widely condemned by politicians. Im not happy about him coming here until that ban is lifted. Look at what is happening with those countries, how many more is going to be . What is going to be the long term of this on the rest of the world . But as a us judge issues a temporary halt to the deportation of visa holders or refugees, nigel farage backs president trumps executive order. Donald trumps policy in many ways has been shaped by what Angela Merkel did. He is fully entitled to do this. In this country, i would like to see extreme vetting. In yemen, us commandos are thought to have carried out a raid, killing at least 30 suspected alqaeda fighters and civilians. A statue of Princess Diana will be built in Kensington Palace by her sons prince harry and the duke of cambridge. The princes said 20 years after her death, the time was right to recognise their mothers positive impact around the world. Now on bbc news, click. This week were heading to space for a spot of sun, shade and. A freaky transforming monkey spider bot. Weve long fantasised about the possibility of life on other planets. But it was only in 1995 that we found the first planet outside our solar system. These exoplanets are hard to find. Of course they are, theyre relatively tiny. And so far theyve mainly been detected indirectly, either by the incredibly slight dimming of a stars light as a planet moves in front of it, or by the wobble of the star caused by something orbiting it. In the last 20 years weve detected about 2000 exoplanets, but we havent actually seen many at all. This is why. Well, the planets are very, very faint compared to a star and theyre very close to a star. The kind of planets where we might find life, an Earth Like Planet Orbiting A Star would be 10 billion times fainter than a star. But if you can see the planets, you can start to look for evidence of life on their surfaces. What you need is something to block out the light of a star. What you need is a star shade. Due to go into space in the middle of the next decade, it is a crazy sounding thing that can be flown in between a Space Telescope and the star to precisely block out the stars light and reveal any planets. Itll be a few tens of metres in diameter, and in order to block outjust the light from that distant star, itll need to be about 40,000 kilometres away from the telescope. So you managed to block out the starlight, you see this tiny dot which is a planet, what actually will we get from that image . What resolution will it be . Will it be a few pixels or will we see it in great detail . What well see is a dot of light completely unresolved. Essentially a single pixel. So that doesnt sound so interesting, but well be able first of all to see how far it is from the star, and by revisiting it, well be able to see what its orbit is, so well know if it might be a planet that can support life, due to its separation from the star. But more importantly, well be able to take that light and put a spectrometer on it, disperse it, and look for signatures of chemicals on the planet. Well be able to see water, oxygen and carbon dioxide, perhaps methane, so signs of life. Indications that this might be a planet that supports life. And this is not even the maddest part of the scheme. See, theres a problem. The star shade wont fit in a rocket. And thats why a big part of the work being done here at nasasjet Propulsion Laboratory in pasadena, and the beautiful solution that theyve come up with, is all about fitting the thing into a tight space and then unfurling it once in space. And the inspiration comes from origami. Wow its really quite impressive. At the end you can see how large an area you can fill with such a small volume of material. But this is only the half of it because you have petals which come out here as well . Yes, exactly. Oh, my goodness. This Cardboard Model is the latest test to make sure the shade can unfurl perfectly when it is all alone up there in the black. The flower shape blocks out the light better than a circle, and those outer petals need to be made to an accuracy of 50 to 100 microns. Youre going to point a telescope at a star and then youre going to fly this into position to block the light from the star . Correct. What if you then want to look at another star . The telescope moves by a little bit but this thing has got to go across the galaxy . Thats right. There are two ways we can do it. We could move the entire shade so the star is over there and we have the star shade, and we have the telescope and we can move the star shade to the next target, or you can move the telescope to reposition. And how long would it take to move . It could take from several days to a week or more, depending on the next target. If i may say, this sounds crazy this sounds like we want to spot some planets, what are we going to do . Well put a shade in space and were going to fly it 40,000 kms from the telescope. That sounds insane. Well, whats really cool about that is there is this insane concept of how youre going to fly this massive shade so far away, 40,000 kilometres away from the telescope, but once you start breaking it down into little problems, you Start Testing and build a petal, you build the truss, you build the shield, you realise piece by piece what engineering needs to go in to that problem to solve it. So we just break it down into little problems that we can solve in a piecewise fashion. And isnt that a great motto for life . Take an impossible problem and break it down into more possible chunks. I love the fact that atjpl you can just wander into a random room and it is called Something Like the Extreme Terrain mobility lab. Thats what theyre doing here. Theyre making robots to cope with Extreme Terrain. This is axel which is a robot with a pair of wheels that can be lowered down cliffs. And this is fido and athena. These are the prototypes for the mars rovers spirit and opportunity. Of course the point about robots is they can do things that humans might want to do but in places that humans cant go. All of these have fairly familiar designs, wheels here, some robots have legs. But kate russell has found one that looks like nothing i have ever seen before. In 2012 the world watched with bated breath as nasa deployed a rover on the surface of mars using a sky crane. This kind of science is incredibly expensive. The rover weighed 900 kilograms, as much as a full grown giraffe. With the equipment required to land it gently, it had to be able to take the weight of 32 giraffes. Total cost, 2. 5 billion. It would have been much cheaper if curiosity was lightweight, came flat packed and was sturdy enough just to be dropped on the red planets surface. Meet super ball, a Tensgrity Robot In Development in nasa ames. This lightweight sphere like matrix can be packed down flat, taking up minimal space in a rocket and vastly reducing launch costs. Because of the unique structure of this robot and the fact that it can deform and reform itself and take massive impacts, eventually nasa will be able to literally throw it at the surface of a planet and its scientific payload in the middle will be protected. Its bouncy. Once deployed, super ball can handle much rougher terrains then a rover, rolling over obstacles and up and down hills. Tendon wires connecting the struts spool in and out creating momentum, in much the same way as flexing your muscles moves your limbs. If it bumps into anything solid, it willjust bounce back. It should even be able to survive falling off a cliff. The next step for super ball is to redesign the robot such that it can actually survive at least a one storey drop. You can expect to see a system like this on an actual nasa mission probably in 15 or 20 years time. Over atjpl, they are working on limbed robots. Its research spawned from the Darpa Robotics Challenge where teams competed to create highly mobile and dextrous robots that can move, explore and build things without human intervention. One of the great things about the simian body plan is that all of our limbs can be used for either mobility or manipulation. And so, if we are putting things together, you could certainly imagine hanging on with a couple of them and doing the manipulation to assemble things together with others, and that makes for a very robust way of putting things together in an environment like zero g where you dont want to float off. The plan for king louis is to be sent into space to build stuff with visual codes a bit like qr codes to guide it. We have a structured environment. We know what we are putting together so we put signposts onto all the bits and pieces of the structure we are putting together that tell the robot a few things. Most importantly, it tells the robot where those things it is manipulating are in space, literally and figuratively, so it can align itself better. The codes will also include Construction Information like which bits go together and how much torque to apply to a bolt. This will allow robots to work autonomously in teams, Building Space stations or planetary habitats faster and more economically than previously possible. But nasa hasnt completely given up on our four wheeled space helpers. Here weve tried to develop new kinds of robots for future space exploration. This robot, for example, is called k rex. Its one of our Main Research robots that we develop and test here in the roverscape at nasa ames. This is a large play area for robots, a Proving Ground that we use to really try to develop things like navigation or do the mission simulations. One of the biggest problems with space travel is getting stuff off our planet. It requires an incredible amount of fuel to break through the atmosphere. So k rexs currentjob is to look at ways to collect useful resources once we are already out in space. Can we go to the moon, find water and use it for oxygen and hydrogen to make fuel and go other places beyond the moon . For you, what is the most exciting sort of new development that is on the horizon . For a long time now we had robots do exploration. We have rovers on mars, they are still functioning today. We have humans in space on the International Space station, and in the future i think what were going to see more of is really human robot teams. Robots might be working ahead of humans, they might be working following up after humans, they might be side by side or perhaps just in support of humans. In any case, what were going to have is a future of robots and humans working together. So, the biggest question perhaps of the day for me, can i drive k rex . Definitely. Lets have you do that. Yes now lots of you think we click reporters have the bestjobs in the world, but after spending a day at the roverscape testing ground, i think there is another contender for that title. Hello and welcome to the week in tech. It was the week that in the us, after much speculation, facebook head honcho Mark Zuckerberg denied he wants to run for president of the United States. Not Everyone Wants to run the world, it seems, just the bits related to social media. Plus, help could be at hand for forgetful apple airpod owners. Apple has created a find airpods feature for its wireless earbuds. It works in the same way as the find my phone feature. No word yet though on how much rummaging down the back of the sofa it will lead to. Plus, Authorities In Dubai showed off a new way of fighting fires. All with the help of a jet ski for traffic avoiding Rapid Response and a jet pack for some elevated extinguishing. Water pressure keeps the firefighter airborne allowing them to target difficult to Reach Fires Near Waterways and then hose them down. Next, never get off the boat. Legendary movie director Francis Ford Coppola has thrown his support behind a Video Game Version of his vietnam war epic apocalypse now. It is going to be Survival Horror and it is going to be financed via crowdfunding. And finally, fashion conscious astronauts have had to make do with any Colour Space Suit they like as long as it is in white. Not any more. Nasa and boeing have revealed details of the new upgraded blue space suit. These are lighter and easier to move in. Personally, id prefer pinstripe. Up on the International Space station, resources are pretty tight. But while food and water do need to be delivered as take out, you might think that power at least might be plentiful. But over their lifetime, the International Space stations solar arrays degrade and produce less power. And as our space aspirations grow, we could do with more and more power anyway from bigger and bigger panels. Thats a bit of a problem. To give you an idea of how much power the iss needs, it has eight solar arrays. Each one is as long and as tall. As this room. To fit something this huge into a rockets payload, as we discovered with the star shade, you have to fold it up. The problem here is each part of the solar array is mounted on a thick protective aluminium backing. The more you fold it to reduce the length, the more you increase the thickness. Bit here at Lockheed Martin in palo alto, Wahid Azizpor is working on a solution. I am constantly surprised by anything that goes into space, about how light it is. It looks quite thick but its so light. It has to be. It costs a lot of money to launch one of these in space so it has to be light. Why did you need that . To make sure the cells did not crack when youre launching in space. Its really violent when it goes in space and on a rocket itself. So its not when its in space, its actually the launching and i guess the unfurling that can damage these things . That can damage the cells. But this is not good enough for you this is the thickness of a normal solar array and you are now making them that thick. Its a substance called kapton and it will replace that thick aluminium support. It feels like a bit of plastic. So what does this mean for stuff that goes into space now, whether it is space travel or satellites . What does this mean . You can put a lot more power, a lot more stuff in space in a small area itself, so you dont need all these things. All you can put is the kapton so if you want double the power, all you need to do is double the amount of that material, kapton, which adds another inch to it and it doubles the amount of power you need. Only a few of us will, of course, ever get into space, but for the next best thing, why not try it in vr . Heres lara lewington. Ive had some really engaging Virtual Reality experiences. One of them simply set in an office, but it seems if you are entering at vr world, you might as well go somewhere really exciting, like space. Thats where home a vr spacewalk takes you. Inspired by nasas training programme, it aims to bring a mission in space to the masses. After getting used to your new surroundings, you undertake an emergency mission. Whilst enjoying views of earth from afar, a friendly hand from a fellow astronaut helps to get you on your way. Ah, i can hold a hand. I feel a strange sense of safety there is another astronaut here. The bbc commissioned the experience last year, as its first steps into the world of Virtual Reality content. Weve taken all the Storytelling Power of the bbc and applied that behind it, so theres a great script, a great narrative and then weve looked at all the cutting edge explorations people are doing around vr, in terms of bio monitoring, Haptic Feedback etc etc and trying to bring that into it as a massive piece of learning really. My preview here on the htc vive saw it set up with a chair providing Haptic Feedback and a Heart Rate Monitor which resulted in my being sent back to base if readings went too high. But apparently im very calm in space. In march it will be released for vive on steam as well as oculus. Wow, this is incredible. Im now looking at vancouver apparently. Some Artistic License was of course needed like making tasks shorter so they wouldnt get boring, but aside from creating the pictures and story telling a project as bold as this needs, there were the usual challenges faced by those producing vr content. In 360 video and Virtual Reality, locomotion is one of the biggest problems. If you move someone without them having made a conscious decision to be moved, it can be very disorientating. To get around those problems in this particular environment of zero gravity on the outside of the space station, we built a system where you move yourself by grabbing handles, so every Single Movement of yourself in the environment is always user initiated and as granular, slow or as fast as you are comfortable with. Oh, goodness i feel most disorientated wow, the depth of it i think was the thing that was most surprising. You really got a sense of being up high, seeing things really, really far away. It took a while to get grips with what i was meant to be doing, but just the fact that i was moving around within space was quite incredible. Whilst it wasnt possible to create a sense of weightlessness, the pictures were amazing, but obviously, i cant vouch for how true to life they are. It is essential to life on earth, but the sun is a Fearsome Beast and cares
