it has flown a spaceship to a one—kilometre—wide near—earth asteroid called ryugu to do some incredible science. this is hayabusa2. it has just deployed three rovers onto ryugu's surface — the german and french mascot probe on 3 october, and before that, the japanese minerva ii robot. their mission — to measure temperature and magnetic properties, and take photos of the surface. and amazingly, this is how they get about. yep, they bounce. i have come to the japanese aerospace exploration agency, jaxa, to meet the team who designed the mission and get my head around this bonkers mode of transport. in summary, this hops off the surface of an asteroid, it jumps about 10—15 metres

into space, it stays... off the surface for about 15 minutes, and then comes back down? bounce and bounce and bounce. the images already returned by the minerva ii bots are wowing the world, but the risks they face are high. actually, so we did not have much budget, so we did not use very expensive devices. the rover hops and then bounce and bounce, so in that moment, the mechanicalfailure would happen, so something was broken. so this is a replica of hayabusa2. and, believe it or not, deploying the landers is not even the coolest thing that this is going to do, in my opinion — because this is going to land on the asteroid, take a soil sample, and then take off again.

which i think is absolutely incredible. the first attempted landing is hopefully going to happen very soon — by the end of october. and then a little later, a second landing will collect more soil. if we can get the organic matter, we can study what kind of organic matter were exist, when the earth was born. that is a model of hayabusa2 there. it looks very delicate to me, and you are going to try and land that on an asteroid. what are the risks, and what is the most risky part? there are lots of boulders. big and small.

we cannot find a wide area with no boulders. so that is our main issue. assuming all does go well, next year hayabusa2 is going to go one better and try to collect soil from under the surface. and it is going to do that by using an explosive to blow a hole in the asteroid. and then, in one final heroic act of science, it is going to fly back to earth and return the soil samples to jaxa scientists, possibly to help them unlock the secrets of life itself. we don't know where the life was born. it may be on the earth, or it may be in the universe. we don't know that. so we want to study the original organic matter that exist when the solar system was born. thank you very much for your time. very best of luck. thank you very much. he is going to land a space ship on an asteroid and then take off and fly back to earth!

now, every year in october, the tech world turns its attention to ceatec, japan's big tech show, which is a fascinating glimpse into the direction this country is taking its innovation. this is notjust another tech expo. it is quirky. yes, that is a sort of green pea alexa. and how about replacing alarm clocks with blowing air from the ceiling to wake us up? even though you don't like to be woken up. it is like somebody quietly going... laughs. so it isjust a question of us finding what we think could be the next big thing. you know what it's like. you are stuck behind a car and you can't overtake, because, you just can't see beyond that vehicle.

well, this car might be able to help you. it is fitted with a demonstration of a new technology called xtravue, and it means that you can see through the car ahead using its camera rather than yours. the vision of its makers valeo is that the live stream from cameras in our cars will be available to everyone within a certain area. the forthcoming 56 cell network will make this tech more workable. imagine not having to guess what it could possibly be that's holding you up. horn honks. lucky escape! here is another angle on cars from mitsubishi. as the viewer changes position, so the car and lighting effects shift with them. obviously the car would not move like this in real life. what it would do is that as you move around it, the lighting and reflections

would change, and that is what this is trying to demonstrate. the hope in the future is that it can be used on billboards so that the objects within them glint and shine as you pass by, as if they were really there. but you had better hope it is a quiet street because at the moment it only works with one person. does it look as though the headlights are following you around the room? look up and see how natural these skylights look. up until now, if you wanted a fake window, the fitting would contain either a blue light or blue glass or perspex. there is actually no blue light behind here, it is just two white leds either side, with suspended diffusers, mitsubishi describes them as, in between, to replicate the way that natural light comes through the atmosphere. they won't give us any more information, and they say it is about two—five years away before something like this could be installed in our homes, hospitals, or maybe even the underground, to give us a little bit

of extra natural light. it is almost like i am expecting to see outside! now another thing that might be of interest to japan's ageing population are these. they may look like normal glasses, but if i press the touch sensor on the side, you may have seen a little flash, and what that was was liquid crystals inside the glasses shifting and what that was was liquid crystals inside the glasses shifting orientation and changing the focus, meaning it's easier to see things close up, just like bifocals. now, the upside of these is that you can then turn them off and goes back to your regular prescription. and we'll finish with something mind blowing, eye—popping, and jaw—dropping. i can't even walk in. it's messing with my perspective. this is borderless. the latest otherworldly experience from digital art collective teamlab. this amazing space is their first permanent home in odaiba in tokyo.

a 10,000 square metre magical transcendent world of projected art that's never the same twice. this is just astonishing. it really is alive. the exhibits react to your presence and your touch. nothing is just played on loop. everything is changing and reacting all the time. behind the scenes, 520 computers and a70 projectors bring to life the work of cg! artists, engineers, and architects. some of the artjust doesn't stay put. characters leave their point of origin and wander into other rooms and across other works. visitors even get their chance to add their own art to the exhibition.

colour an animal, scan it in, and it comes to life, joining the user generated menagerie that is flying, swimming, and crawling the floors and walls. the other reason it's called borderless — thanks to all the mirrors some of the works seem to go on forever. it's certainly a place where time becomes irrelevant, until you really have to leave. and that is it from japan for this week. i cannot think of a better way to end the programme. don't forget — we live on facebook and on twitter and we will put up loads of backstage photos and videos there. the address is @bbcclick. thank you so much for watching. we will see you soon.

hello. many of us have been basking in warm autumn sunshine this weekend. certainly the case in east anglia, the coast of suffolk, plenty of sunshine today. slowly through the day the cloud has been moving down from the north and west, bringing some patchy light rain and drizzle in places. this is the scene in staffordshire earlier this afternoon. the cold front is weakening all the while. all that is left now is really some patchy cloud and that too will claye south and east was after midnight. behind it, clearer skies,

behind it, clearerskies, a scattering of showers for more than western scotland where the winds will be quite strong, 50—60 mile an hour gusts and a cold night for the north compared to recently, some moral spots getting to freezing. we start the new week across much of the uk finance dry. plenty of sunshine. there will be more cloud for the far north of scotland, outbreaks of rainfall orkney and shetland made french parts of the mainland but elsewhere mainly dry. windy, these are average speeds through the afternoon commute can see the strength of the win through northern and western scotland where gusts will get up to 50—60 miles per hour and gusts will get up to 50—60 miles per hourand a gusts will get up to 50—60 miles per hour and a cooler feel, gusts will get up to 50—60 miles per hour and a coolerfeel, io—iidc. it's a cooler feel across the uk behind the cold front, so iz—ilidc is the top temperature tomorrow afternoon despite some sunshine. we will end the day dry but the wind continuing to strengthen overnight across northern and western scotland, further outbreaks of rain connected to the front which is stretched across the pop top of the area of high pressure. notice the squeeze on the isobars bringing

stronger winds. the area of high pressure is the predominant feature through much of next week. on tuesday more persistent rain for scotla nd tuesday more persistent rain for scotland particularly the further north and west you are. further south and east, mainly dry, cloud into northern england and northern ireland on tuesday. further south is where we'll see the best of the sunshine, good spells of sunshine to the east of the pennines helping temperatures up to 15—16, some wild once again. a similar day on wednesday, this time we've lost the front from the far north of scotland so front from the far north of scotland so aside from one two showers it's mainly dry here, maybe more cloud around on wednesday where we've been used towards blue skies and sunshine but temperatures up to 15—16. however as we go towards the end of the week notice our big yellow and orange colours, the milder air, gets replaced with blue colours. a blast of arctic air coming down from the north as we go towards the end of the week and not only will be feeling cold and the strong winds, there's also the chance we could see some snow over the hills of scotland and northern england. bye—bye. this is bbc news.

i'm carole walker. the headlines at eight: the uk, france and germany issue a joint statement condemning the killing ofjournalist, jamal khashoggi inside the saudi consulate in istanbul — and call for urgent clarification of what happened. the brexit secretary dominic raab says the uk could agree to extend the brexit transition period by about three months — but only if the eu drops its demand for a northern ireland ‘backstop‘ if you think about it, as important as it is, these are the outstanding issues that ought to be the stumbling blocks. on the vast range of other issues, we are pretty close to getting them. russia criticises president trump's decision to pull out of a landmark nuclear weapons treaty — calling it unacceptable and dangerous.
