this is bbc news. the headlines. china's presidents is spread of the new strain of coronavirus is exhilarating and putting the country ina grave exhilarating and putting the country in a grave situation. experts say human to human transmission is the only plausible to explanation for the scale of the epidemic. it is known to have killed at least 56 people. lawyers representing donald trump in his impeachment trial say the president has done nothing wrong. they say the democrats in the senate have not shown he abused his power and were attempting to remove him from office before the next election. the turkish president has met rescue workers searching for survivors of the earthquake on friday. 29 people are known to have died and over m00 have been injured. residents have been warned to not return to damaged buildings because of possible after—shocks. those are the headlines. now on bbc

news, it is time for click. this week, building the next generation of spacecraft. dropping in on china. and ripping up the streets of post brexit london. three, two, one, zero. getting into space is an expensive, dangerous and highly complicated business where hundreds of thousands of decision made parts all have to work together perfectly.

if they don't. .. all have to work together perfectly. if they don't... but all have to work together perfectly. if they don't. .. but as all have to work together perfectly. if they don't... but as the race to space heats up, commercial ventures are looking for simple cheap and quick alternatives to building spacecraft. and here in la, ifound a start—up trying to solve all of those problems in the unlikeliest of ways. by 3d printing rockets. this is relativity space. existing rocket bits are not 3d printed. what is the advantage of 3d printing? from our perspective it is flexibility. factories have tons of fixed tooling, expensive, hard to change and you have to retool the factory to change a product slightly. for us, we to change a product slightly. for us, we can to change a product slightly. for us, we can change all that in software. it is digitising the

process and applying flexibility whereas if you press new code, you can makea whereas if you press new code, you can make a different product without changing any hardware. after a stint at spacex, jordan formed relativity space with his friend and ex— blue origin engineer. the two realise that sd origin engineer. the two realise that 3d printing could help in several ways. because it builds objects layer by layer it can produce complicated structures from a single part. also, much of the manufacturing can be done autonomously. and that leads to a rather remarkable aim. team wants to send robots to mars which can then build rockets on the surface and that means that the astronauts who eventually lent their will have a way of getting home. it is better, cheaper, faster. it will evolve more quickly than other technologies and

we will launch factories to mars to build things like housing and spare parts and infrastructure and eventually leading up to printing the first rockets. why has no-one done this before? no-one has had a printer big enough to print something that big. much of the challenge we had as a company was making printers enough to make an entire rocket. this is what the printing process looks like close—up. a robot arm weaves backwards and forwards to lay down a thick layer of special high—strength aluminium alloy. so this is it. the world's largest metal 3d printer. it is currently printing the top of the first stage of a rocket, the first bit that burns its fuel and then is jettisoned. this is the top of that. and if you look really closely you can see that it is slowly rotating. it takes about one hour to go all the way around at the moment and

that means the robot arm with all the hot stuff and liquid metal stuff, can stay relatively still as it weaves each layer. that means you get a lot more precision. the whole thing will take about 10—12 days to print. i can wait, i don't know about you. and why have one giant 3d printer when you can have several running in parallel? they are basically off—the—shelf robot arms, arc welding different rocket stages that, when put together, can stand 30 metres high. in its first five yea rs, 30 metres high. in its first five years, relativity space has already secured contracts with nasa and others to and next year and hopes to make its forest launched from cape canaveral in florida after becoming only the fourth commercial company to secure a launch there alongside the united launch alliance, blue origin and its la compatriots spacex. and, sometime after that,

mars beckons. and the promise that anyone who journeys to the red planet is not making a i—way trip after all. departing the planet may bea after all. departing the planet may be a trip forjust a few hardy souls. but this friday, more than 60 million will be making an historic departure themselves. don't switch off because where we are going as ever so off because where we are going as ever so slightly passed the non— bonding of big ben onjanuary 31. we are going a few years into the future where, according to the makers of one videogame, things post brexit are not going well. the game is the highly anticipated watchdogs legion in which the makers suggest that society has, shall we say, deteriorated a bit. mark was invited by the company to their hq in toronto to have a special look inside the game before the launch.

this is not the real piccadilly circus. none of this is real. come to think of it, i am not even real. this is a virtual version of me reporting from inside a videogame. r, london. had a good run there for a while. watchdogs legion imagines a dystopian vision of a post—brexit britain. a surveillance state and an oppressive regime. the player assumes the role of an activist and hacker who must recruit in game characters to their cause to ultimately bring down the government. we need to recruit a resistance. legions is the third instalment in the popular franchise developed by ubisoft. we are taking a lot of influence from what we see in the world. whether it is the current political client asthma climate, whether emerging

technology. we find ways that we are inspired by those things and ways that we may be a bit afraid of these things and then we extrapolate out. a large area of london has been mapped for the game and every character you meet is playable. the back story and personality as well as characteristics. they are filled in by the artificial intelligence when the player approaches. any character you see in the world, they are kind of at a level of dumbness. and then as you pay attention to the characters they get smarter. as you profile them and as you get more interested in them and decide to recruit them, we layer in more complexity but we always keep it consistent with what you initially saw. technically, interesting innovations but is it asking for trouble using real—world events like exit ina trouble using real—world events like exit in a game? the british people have spoken and the answer is we are out. i went to put that to the game's creative director but in this interview we will attempt something that has never been done before. i

will perform an interview with a developer of the game inside their own videogame. in order for my 3d model to be created we will need a whole bunch of images of me and that is what will happen in here. to do this, every minute detail of my face and body needs to be scanned so i can appearasa and body needs to be scanned so i can appear as a game character. three, two, one. was great it is not like a photo booth at the railway station. it is incredible how little there is. next, on with the performance capture suit with dots painted on my face and i am fitted with a head rig that captures my facial movements. be honest with me. how do i look? is someone going to call action forest? now we are ready for virtual lights, camera, action.

clint, why did you set this game in london? i think london is an incredibly silly to set a videogame in. it is notjust full of culture and historic landmarks and all kinds of amazing places the people want to go to and visit, it is also an incredible city full of cultural diversity. it was really important for us to make sure we were simulating notjust for us to make sure we were simulating not just the for us to make sure we were simulating notjust the city for us to make sure we were simulating not just the city and everything going on that you see around me but also the population and her people. brexit has been hugely divisive in the uk and quite a lot of people will be quite angry that it has been included in a videogame. well... i look at it as a creator of culture, if we were creating films or movies or books it is the same with video games to to get is our responsibility to look at the things that are happening in the world around us and have something to say about it, create something meaningful that people can look at and engage with and that it speaks to the world they live in. this game

has been in development forfour yea rs has been in development forfour years and local events move quickly. have you included any more of those events in the game itself? things are changing around us all the time and every day we have to look at what is happening in the world and make decisions about what we will be able to include in our simulation. we look at drone regulation, autonomous vehicles and we have to think if these are things we want to include in the simulation to make playable for players a game universe? about it a great deal. thank you very much indeed. this as market for bbc news in a virtual version of london. welcome to the. it was the week that saudi arabia was accused of hacking the phone of amazon's early on i found out. the crown prince is alleged to have sent an encrypted video file via whatsapp which saudi arabia denies. it was revealed that since the introduction

ofg revealed that since the introduction of g dpr in 2019, hundred and 1a million euros in fine have been imposed with regulators handing out the biggest in france germany and austria. is it a burn, is it a plane? yes and no it is a pigeon. researchers have built a robot bird using real pigeon feathers detect the team believe their findings could inspire future aircraft wing design. quite the... coo. how would you feel about sharing a ride in a d riverless you feel about sharing a ride in a driverless car without a steering wheel? this car is also missing pedals and a rearview mirror. it is that make its developers which include honda in the hope that multiple occupancy electric vehicles will reduce emissions accidents and congestion sitting and finally, spending too much time on your smartphone? google suggests putting it in an envelope to google envelope

is an app used in conjunction with a paper cover you can print out at home. it can dumbed down your device so we can home. it can dumbed down your device so we can only make and receive calls or transform it into a photo and video camera with no screen. although it only works on pixel three. will it work? answers on a postcard. a couple of years ago amid terrible wildfires in the us, we went on location with california's firefighters to see how they were using technology to battle the blazes. drones have become a big tool in the firefighters arsenal. but for how much longer will they fly? earlier this month, the donald trump administration called for all chinese made drones to be banned from governmental work. and where are most drones made? yeah. that is right. fears were raised that they

could be used for spying and the us 110w could be used for spying and the us now wa nts could be used for spying and the us now wants its own drone tech to catch up with china. this then is another technology battle brewing between the us and china to and could this ruling ultimately affect innovation in delivery? and with such a large population, china is looking at this and many other ways to speed up the delivery process. it is already making a lot of headway so is already making a lot of headway so could president trump ‘s anti— chinese stands now end up stymieing us innovation in this area? stephen becker delivered this from china to from china. think of something like this, or maybe this. well, how about this? so this is the testing headquarters in gwungjoo and this is

their passenger drying that they are developing and the idea is this could ferry passengers from eight to be around the world and could even fly in the skies in the next couple of months, it can go 135 miles an hourfor of months, it can go 135 miles an hour for 35 kilometres of months, it can go 135 miles an hourfor 35 kilometres or of months, it can go 135 miles an hour for 35 kilometres or so and if it takes off you could imagine it would be a quick way to get around. this is what it looks like inside. a little cockpit you can climb into. you can close the door. make yourself nice and cosy. there is even a seatbelt. this can carry up to 220 kilograms, so a couple of passengers, and it is pretty cosy but if it gets you there quickly it could be all right. the whole aviation industry has been, you know, existed for a century and there was nothing fundamental changed in the past century. the company started to think about passenger aircraft, self piloting ones, starting from many years ago and we thought is there any alternative? is there any way we can make a safe or, you know, aircraft?

in the future? at the moment they are working on getting commercial approval to fly flights over the city but they have not got it yet so it has to go unmanned at the moment so we it has to go unmanned at the moment so we will just it has to go unmanned at the moment so we willjust have to watch. wow! that is that is pretty serious! imagine that flying over your city! you would definitely know about it! it is certainly a glimpse into the future and it could make delivery people and packages very quick indeed. but instead of going physically faster, another way for deliveries to arrive sooner is to sort them closer to where they need to go.jd .com, sort them closer to where they need to go. jd .com, china's biggest online retailer, has been trying to dojust as in beijing. people in china don't tend to drink a lot of ta pwater china don't tend to drink a lot of tapwater which china don't tend to drink a lot of ta pwater which means that china don't tend to drink a lot of tapwater which means that it is at least they are tending to drink bottled water instead which means it needs to be delivered to the house and if it is doing that it needs to come from a place like this which is a water station. to get water at the

moment you have to phone one of the many local companies. it is very manual and can be slow. people are fio manual and can be slow. people are no longer satisfied with a 24—hour or even half day delivery. what they wa nt or even half day delivery. what they want isa or even half day delivery. what they want is a situation where say you are making dinnerat want is a situation where say you are making dinner at home and unit price of water delivered to your kitchen asap, and it is. jd could be called china's ansa to emma's on and it has big warehouses which means they can only be so close to the centre of a city and that is where the water stations come in, dotted around beijing, they are essentially around beijing, they are essentially ajd around beijing, they are essentially a jd depots around beijing, they are essentially ajd depots in miniature. so now you order water on and up and jaidee automatically sends the order through to abortifacient close to you. it could be one just around the corner, and they say that makes it really quick ——jd. —— since the order through to a water factory near you. she is about to put in an order and we will chase it and see if it gets there. put the order in, waiting for it to come through. very

exciting. follow that chapter! —— tuk—tuk. it took about 20 minutes and i think thatis took about 20 minutes and i think that is the fastest it can be and it can be anywhere from 20 minutes to a couple of hours, depending where they are in the city and how busy they are in the city and how busy they are. all of this innovation may only be possible because of a unique situation in china. china delivery workers often not contracted and they are not paid minimum wages or have any kind of social security net and they are basically earning money ona and they are basically earning money on a piecemeal basis of, say, you know, 50 cents every delivery that they make. that needs —— leads to a huge number of precarious workers that really are supplying the foundations of the online economy in china. in developed economy like the

uk where there is minimum wages and wage levels are generally higher the cut delivery drivers would take of many services would make them possibly unviable for many people. the company has also been working on a trial to deliver amongst other things fast food. this app actually lets you get things delivered to you by drone and there is a few different options, different people that are offering the service. we will get some fast food today and i think we will order six coffees because there is a few people here. there is only one nearby which is the one just there is only one nearby which is the onejust outside there is only one nearby which is the one just outside and if we pay 110w. the one just outside and if we pay now. we should have some coffee. touchdown! if i can get into it. this is a copy that looks like it has come from, it looks like, mcdonald's. so let's see if i can get into this. it is slightly more

complicated than a cafeteria. now, back to wherever it came from. i'm not entirely convinced you were doing to order a coffee but you can imagine if you needed an urgent parcel or something it could be pretty helpful but you do not want that landing in your backyard, do you? i think drone pods like this make a lot of sense. no doubt that what they are doing in delivery here is pretty innovative but the question is can the business models that make sense in china still work in other places around the world? in the race to go global, the real challenge could be making sure that regulation and safety come along for the ride. that was steve in china. now, earlier than normal, we find ourselves in oscar's season. it is the academy awards in a few weeks time and between now and then we're going to be meeting the people behind the most innovative developments in the movies that are up developments in the movies that are upfor developments in the movies that are up for the awards and we start with this monster hit. whatever it takes.

this show has so many challenges, i think because it is such a pinnacle of the marvel universe. can we get a photo? it was a challenge because we we re photo? it was a challenge because we were taking out facial animation to places we had not been and to get that level of performance was definitely a real challenge. when they were shooting, they shot with mark ruffalo in place and he would wear a motion capture suit and also some had cameras to capture his facial performance and it meant once we got the shots turned over to us we got the shots turned over to us we had a good amount of reference to get started with and we have this amazing performance from mark, if you put 100% mark on to smarthog, it would not look like smarthog, it would not look like smarthog, it would look like mark pretending to be smarthog so we had to find the character using some machine learning techniques to enable us to capture his performance and very quickly off of that footage put it

onto an initial model and trying to get that really finessed the human form which is one of the hardest things to do in c6 and something else we took from the machine learning information was some of the really small micro movements, although we did most of it in hand animation, it is important that we could take these tiny little micro movements, very small bits of eyebrow movement and chick movement, just really subtle stuff that you would feed it back over the top of the hand animation to really capture the hand animation to really capture the performance. the biggest problem i think we faced was actually the quantum suits that the avengers way because when they shot it, way back before infinity war, there was no design for the suit so nobody was wearing a suit and no suit was ever built so we had to work out several things. one was how we're going to place everyone costumes because they would be shot in whatever costume the avengers happen to wear and sometimes it caused quite a few problems. some of the costumes had very high collars so the new suits

they were wearing would not be covering all of that costume so there would be bits of the neck visible and we would have to create using cg visible and we would have to create using c6 or painting it back. in some shots, establishing shot when they first walked into the hangar altogether was actually shot with stand ins and down the line we needed to replace everything so we ended up replacing their heads as well, sometimes with a double, sometimes using pieces of plate from other shots that we could find a nice side view and stick it in if it was quite wide the other thing to bearin was quite wide the other thing to bear in mind is with the shots we had to integrate the lighting on the suits into the plate as well. so we built a full cg hangar which we needed anyway because if you look at the plate, because actually used, there was a green screen behind them for whether windows are. and even though the green screen was outside of the windows we had to replace all of the windows we had to replace all of the windows we had to replace all of the windows, simply because we needed to do reflections of what we we re needed to do reflections of what we were putting into the building a nyway were putting into the building anyway so by the end of the day the only thing that is left those shots was actually from what was filmed is their heads and part of the ceiling.

so we replaced the hangar as well. so we replaced the hangar as well. so actually there was one shot in particular for and manned the right of the beginning of the time travel testing, he introduces this man and it was originally at a different sequence it was originally at a different sequence shot in a different part of the hangers of the background was wrong so we the hangers of the background was wrong so we had to take that and change it and change the environment, change the fan and then he was wearing the wrong costume so we ended up replacing his costume as well to put him into the art man quantum suits that he was wearing for the rest of the sequence so that was another sort of last—minute singleshot design of a costume to match something exactly like the re st of match something exactly like the rest of the shots. people like to see the big flashy effects, satisfaction comes a lot of times from doing work good work that nobody realises is there. so clever, isn't it? we will look at the secrets behind another oscar nominee next week. that is it from us from

la. there will be back here in a few weeks time for the academy awards. and during this week, why not follow us on and during this week, why not follow us on social media, youtube, facebook, instagram or twitter. your choice. we are at bbc click. thanks for watching and we will see you soon. hello. sunny skies are on the way back, but it's going to feel colder. there will be showers and it will be windy. it all follows a spell of rain on sunday, low pressure making things very changeable again after high pressure, which may have kept us dry but certainly recently, it has given us these grey, gloomy skies, and it did again on saturday. sunday starts without a frost. dry across the east, except for the odd shower. wet in the west. the rain from this weather front moving west to east across the uk on sunday.

behind that wet weather, we're in the blue. this is the colder air coming in. within that, there will be sunny skies to start the new week, also showers — cold enough for those to be wintry in places, as we will see in a moment. let's follow the progress of sunday's rain. quickly out of northern ireland, pushing through scotland in the morning. the sunshine comes after the rain. it should clear northern england, wales, the west of england into the afternoon. turns a bit brighter there. still there to end the afternoon across east anglia and south—west england. wintry on hills in scotland. a windy day. with the rain, it turns colder, so that combined with the wind will make a chillier feeling to things during sunday afternoon, despite the fact the sunshine reappears in places. with that cold, our showers move east on sunday night. we focus on northern ireland, northern england and scotland, because here, some of those showers will fall as snow on hills — relatively modest hills and quite low levels across some parts of scotland. a few centimetres in places possible.

ice on untreated services going into monday morning, so don't get caught out by that. monday, yes, there is some sunshine around. the eastern spots will stay dry. showers pushing into the south and west will be heavy, possibly thundery, maybe some hail. wintry across northern hills. a bright but blustery day for many of us. again, that wind is a factor in making for a colderfeeling to things compared to recently. low pressure stays in charge of our weather for the rest of the week, initially anchored towards the north—west here, and bringing in the showers, especially towards the south and the west of the uk. so the week will start with a colder feeling to things compared to recently. some frosty nights around as well. there will be some sunshine, but we have noticed some showers, cold enough for some of these to be wintry, especially across northern hills. windy through the week with low pressure close by but by the end of the week, it will start to feel different again and temperatures are on the up. unsettled, yes, dominated by low pressure and changeable, but later in the week, although it's still windy and wet

at times, it does look milder.

this is bbc world news. our top stories... chaya's president was the spread of the coronavirus is exonerating 56 people are confirmed dead. we report from inside the isolation zone where the outbreak began. police have told us that we can drive in but we can't drive out stop it seems that this whole province whether coronavirus first broke out is now going to be locked down. a powerful earthquake strikes eastern turkey, many people are missing. the fightback begins for president trump. and so david attenborough thanks a citizens
