about the possibility of life on other planets. but it was only in 1995 that we actually found the first planet outside of our solar system. these exoplanets are hard to find. of course they are, they're relatively tiny. and so far they've mainly been detected indirectly, either by the incredibly slight dimming of a star's light as the planet moves in front of it, or by the wobble of the star caused by something orbiting it. in the last 20 years we've detected about 2000 exoplanets, but we haven't actually seen many at all. and this is why.

well, the planets are very, very faint compared to a star and they're very close to a star. the kind planets where we might find life, an earthlike 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 star's light and reveal any planets. it'll be a few tens of metres in diameter, and in order to block outjust the light from that distant star, it'll need to be about 40,000 kilometres

away from the telescope. and this is not even the maddest part of the scheme. see, there's a problem. the star shade won't fit in a rocket. and that's why a big part of the work being done here at nasa'sjet propulsion laboratory, in pasadena, and the beautiful solution they've 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! it's 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 at 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's all alone. 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. if i may say, this sounds crazy! this sounds like we want to spot some planets, what are we going to do? we're going to put a shade in space and we're going to fire it 40,000 kms from the telescope? that sounds insane. yeah, but what's really cool about that if there is this insane concept of how you're 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. yeah, and isn't 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. that's what they're doing here. they're 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 prototype is 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 can't 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 baited 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 of a full grown giraffe. but 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 planet's surface. meet super ball, a tensgrity robot in development to 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. it's bouncy. once deployed, super ball can handle much rougher terrains then a rover, rolling right over obstacles and up and down hills. tendon wires connecting the struts spool in and out to create momentum, in much the same way as flexing your muscles moves your limbs. if it bumps into anything solid, it'll just 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. 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 hasn't completely given up on our four—wheeled space helpers. here we've tried to develop new kinds of robots for future space exploration. this robot, for example, is called k—rex. it's one of our main research robots that we develop and test here in the robotscape 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. so, the biggest question perhaps of the day for me, can i drive k—rex? definitely. let's 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. i've 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. that's where home: a vr spacewalk takes you. inspired by nasa's 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. we've taken all the storytelling power of the bbc and applied that behind it, so there's a great

script, a great narrative and then we've 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 i'm very calm in space. in march it will be released for vive on steam as well as oculus. wow, this is incredible. 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 wasn't possible to create a sense of weightlessness, the pictures were amazing, but obviously, i can't vouch for how true to life they are. hello and welcome to newswatch with me, samira ahmed. it's been a long week in us politics but did bbc news go overboard in how it covered donald trump's inauguration and first few days as president?

and was it in the uk public interest to focus in news bulletins on the failure of a trident missile test last year? it's been a busy and controversial first week in office for donald trump and we've heard plenty about it on bbc news. it all started of course last friday in washington, dc. i. dc. i, donald john trump do solemnly swear. . . i, donald john trump do solemnly swear... that i will faithfully execute... swear... that i will faithfully execute. . . that swear... that i will faithfully execute... that i will faithfully execute... that i will faithfully execute. . . the execute... that i will faithfully execute... the office of president of the united states... the office of the united states... the office of president of the united states... and will do the best of my ability. and will do the best of my ability. and will do the best of my ability. and will do the best of my ability... preserve, protect and defend... preserve, protect and defend... preserve, protect and defend... the constitution of the united states. before and after donald trump took the presidential oath of office there was hours of

coverage of the ceremony plus speeches and analysis shown on three channels, bbc one and the news channels, bbc one and the news channel while showing exactly the same coverage with live coverage from washington from the bbc‘sjon sopel and katty kay, while bbc parliament was showing the same live feed provided by c—span but without the bbc commentary. it was all too much for leo mccann and kate reed, who wrote: nick bishop had also had enough before the end, e—mailing: well, we put those points to bbc news and they told us: since last friday we've heard

further complaints about the prominence in news headlines of the activities and pronouncements of the new president. the white house is accused of telling falsehoods in a battle with the media about president trump's inauguration. the president opens his first full week in office by signing an order withdrawing the us from a major free—trade deal with pacific rim countries. he meets business leaders at the white house and once he will penalise american companies that movejobs penalise american companies that move jobs overseas. more executive orders signed by president trump, this time he
