now on bbc news — click. this week, alasdair gets a special tour of the uk's national satellite test facility. but will he ever make it out? once we close the doors behind us, you won't get wi—fi, no—one can hear you scream. whip the cream top. we take a look at how the us's proposed and then shelved ban on tiktok is affecting influencers there. we go behind the scenes

of the disney blockbuster that has no sets and no locations. why... why do you have to massage the muscles sometimes? so, it wasn't intended that we are so close l to nature, but, yes. there you go. everyone needs a massage. orbiting above us are thousands of satellites. theirjourney to space starts in rockets of all shapes and sizes. but before satellites can be sent into space, they've undergone years of testing.

launch and in space. if it's in low earth orbit, it's difficult to fix. and we're on a tour to find out about some of those tests rather strange room. this is our electromagnetics facility in the nstf. it is giant. it's massive. yeah. it's about 18 metres by 18 metres on the floor space. and i think it's about 15 metres high. it's a similar order of magnitude up there.

and what does it allow you to do? auto—compatibility testing, and electromagnetics testing. in effect, this is a room that you can completely block out any signals or anything from outside? you won't get wi—fi, you won't get phone signal. no—one can hear you scream. all of those things. this is like what we've got on the walls and the floor. if you give that a feel... give it a squeeze. yeah. that's a bigger version of this, which is polymerfoam how many of these are on the walls? it looks like it. or of that order, yeah.

facility is supersized. impact sound will have on it. so this is what we call direct field acoustic noise testing. it is random noise. field inside that. would occur during blast off. a lot of it is... you can get very high frequencies. bolts will undo and... literally... yes. ..unwind? because we go...

some of the tests go up to 10,000hz. so effectively, 10,000 sort of movements in a second. it's, effectively... thick walls for internal and extremely thick for going an aircraft carrier deck. you'll hear a rumble. everyone will know what we're doing. one of the biggest features of this new testing facility it's so big, the building had to be constructed around it. this one is still being commissioned, but in a building next door they have a slightly smaller one in use, why are we so suited and booted for this task? yeah, it is essentially

to stop the fallout of the dirtiest things we have, which is humans. and stay in the air, and we're trying to keep it incredibly clean. require planetary protection levels of cleanliness, so we can't contaminate them with human items. so, this is our thermal vacuum chamber — to get things really warm or really cold. rachel is working on the ariel mission, which will see which are very far away beyond our solar system. they will use an engineering test model in this room to see what impact temperature has. that's to bake off any things that are left and then we're going to go very, very cold

so, this chamber can go up to 100 celsius in hot. we generally only go to about 80, just for and then it can go down to 90 kelvin cold, so —180 degrees c, using liquid nitrogen. but for ariel, we need to go even colder because it's and have a second stage of cooling inside this chamber. discoveries, to tasks like sending a message is on the way. come, kiara. i'll tell you a story.

we built all the environments in unreal, and then we had the animators animating the characters in those environments — the director having a monitor so he could and finding his angles. we developed a system called quadcap, where the human would have his legs be the front legs of the animal, and we would simulate the animation of the rear end of the animal so the actor could move around and react with each other. but on your screen, it

would be the animals. so that was a little bit of revolution on this movie — being able to freely direct those virtual characters live. back to the trees. we're trapped! we have to swim. no, we have to fight. if we fight, we die. of all, but also artistic. the environments, for example, are so vast and big, and for this movie, we are visiting the entire places to have references, bring them back, and then be able to start building them from this material. we had 77 sets, different sets, like savanna, canyon, mountains, rivers. trees, rocks that we would set—dress everywhere

that was the technical challenges. but there was also the creative challenges with barryjenkins and his dop, james laxton. animals, would hold close—ups, extreme close—ups — to a wide view, to come to a very close angle sure that we would be able to render them. so, on mufasa, we have approximately 30 million details on him. it took mpc a team of 1,700 people to make 1,500 shots. some of the most complex shots

in the movie would take about two weeks to render before we could see some images mufasa, it is your time. dbb see is one that appears to respond to queries with skills rivalling it

about get this — milk. all righty, we can go ahead and commence. she laughs becoming a milk influencer, or a dairy queen, i don't know if you can see this. if you look in the top, it's just straight cream. it went viral. i was like, "ok, keep rolling with it." mm—hm. yep. tasting and reviewing dairy products on milktok.

deals with brands. in total, from 2024, i've made like five straus family creamery, featured in shoo's first the company has been selling organic dairy products, sales rise by up to 20%. users, 34 followers. by the time we finished last year, after we went viral,

or face a ban. with the company declining to sell, the ban was meant election took office. of the law that the biden administration left, you know, donald trump with. hello. hi. can i take your order? telling its 170 million american users it was fortunate that he was working with them on a solution. some have called it a stunt that left trump the winner, but not everyone agrees. they thanked their saviour — which is exactly what you do when you're so desperate. and milktok will last. it's not a community that we

can bring over to instagram. it doesn't translate to facebook. i think it would be a real struggle for us to capture media channel. laughter time flies when you're drinking milk! i know. as for shoo, she's trying to grow her community you have to diversify because i think relying on just one platform is a little bit dangerous. in a political storm. nice. and grabbing and fetching. this is a place where robots are less robotic and more

might be better suited to work in the real world by asking the question... that's actually more lifelike? and that's why i've come to meet pele. footballing legs. this early prototype is unlike most robotic legs i think i've come across. see, most robot arms and legs move using motors in the elbows or the knees, but this actually takes a lot of power. the joint has to twist those long limbs from just one end.

straight again. just look at how hard a knee motor has to work and how hot you have little bags filled with oil and an electrode on either side. or we could go a step further, biomimicry in some way — while there's almost nothing in nature that uses rotary motion. i think if you want to have

something with the same amount like, if you look at our arm, the eccentric application to be quite flexible. rigid motors that do these motions, but instead i can use multiple muscles, multiple bones that allow us to do these complex motions. institute and eth zurich. and as thomas and toshiko have discovered, pele doesn't even need complex sensors to avoid obstacles or balance as it climbs over them. no, itjust bumps into things and bounces over them.

chuckling why... why do you have to massage the muscles sometimes? so i guess there is something called charge retention — and in the insulating film that kind of accumulate and then stick together, just like... because of electrostatics. yeah. it wasn't intended that we are so close to nature, but, yes. there you go. everyone needs a massage. now, while pele boings in the air like he just doesn't care, the rest of the robots around here are most robots are made of hard materials,

like metal, for example. and that's a problem if you're sending them out into the real world. these things out into the wild, and if they smack into something, nobody gets hurt. of give on your gripper. your hand, the floor... but there is a problem. prototype robot parts are usually 3d—printed and it worked up until now. your printer deposits microscopic particles of your material down. but the problem is,

that means you can only use certain kinds of materials. and that means that we haven't been able to 3d—print and instead of trying to flatten them off, a laser scans the top of each particle and works out

and tendons, for example — don't like humans? no problem. here's a pup that's positively pneumatic. yes. yeah. and then it makes different parts of the legs move. for example, this inflates and it would move this leg forward. and then when i remove the air, then it would spring back to its original position. and this is why it's important to have a material that springs back quite quickly to its original shape. yes. and navigate their environments and cope with the unpredictability of the real world. where thousands of hands can practise and make mistakes in a fraction of the time one real one could.

and that's it from us for now — from me, from pele generally it's been on the cold side. wind and rain, mainly towards the north and the west. so for the first main week of february it will start of the country, with some wind and rain for a time before it in for the end of the period. now, this weather front

has been pushing into northern england, wales and the south west. to the west of it, brighter and eastwards again. clear skies the far southeast mean it could be quite chilly. and you can see further north and west where we have the breeze and those weather fronts and the cloud and rain it will be less cold. gusts up to 50, 60mph winds lighter in the south than what they'll be further north.

and a mild day to come. double figures for most, we could be up to 13, maybe 1a degrees, for example, in the moray firth. now, monday night, that weather front spreads southwards colder behind that cold front. band of rain spread southwards and eastwards, tending to weaken as it does so. the rain, but turning colder. high pressure builds in from wednesday onwards. that will settle things down and it sticks with us
