onto the red planet. facebook �*unfriends' australia — the social networking giant blocks access to news media in australia in a row over paying for content. the labour leader proposes british recovery bonds — to help fund the renewal of communities and jobs after the lockdown ends. terrible, terrible house" damp, infestations and leaks — how some of those shielding from covid are living in substandard housing. good evening and welcome to bbc news. scientists say there's been a strong decline in the number of covid infections in england since the latest lockdown began. researchers at imperial college, who have been tracking the pandemic, say infection rates have dropped by two thirds. but there are warnings that virus levels are still high, particularly among the under 25s. the vaccination programme also appears to be having a positive impact on the number of deaths being recorded. but concerns remain about certain groups of people, among them some black and asian communities, who are not taking up the vaccine when offered. here's our medical editor fergus walsh. lockdown is working — draconian restrictions on society mean coronavirus has fewer chances to spread. but that is meant closing schools, shops, pubs, gyms, putting normal life on hold. the latest evidence comes from 87,000 tests sent out to households across england. the survey by imperial college from the fourth to the 13th of february is good at picking up cases among those who don't know they are carrying the virus. the survey found that infections had fallen by two thirds across england in the past month and are down 80% in london. the researchers estimate that infections are having every 15 days, but they warn that prevalence of the virus is still high, with one in 200 people across england thought to be positive — similar to levels seen in september. we know that the prevalence of the virus was much lower last summer, something like ten times lower, and clearly be more people who have the virus, and some of them will not have symptoms and not know they are carrying the virus, the more likely to do is to transmit to other people, so the lower we can get the prevalence, the better. there are still nearly the same number of covid patients in hospital as at the first peak in april last year. but there are now tentative signs that vaccines are beginning to save lives among the over 80s, the first to receive a covid jab. deaths among the over 80s have fallen by 54% since the middle ofjanuary. much of that is due to lockdown, but they are falling faster than in younger age groups, where they are down 44%. as more and more people get vaccinated, that should start bringing down cases as well as deaths. at the minute, the over 70s, they only make up about 10% of cases but over 80% of deaths. as we start vaccinating younger people, that effect we should also see more and more in cases. but there are concerns about the lower take—up of vaccines among black, asian and minority ethnic communities. at this vaccination centre in east london, staff say some people book for a vaccine and are not turning up. you don't have to be scared about it. before you know about it, the needle is in and it is out. some people are so scared, but they say, is that all? and i say, yes that is all, we are here to help you. you may not always trust - what you hear and what you see, but you can trust the vaccine. a video urging people from bame communities to get the vaccine will be shown across commercial television channels tonight, and the nhs plans to distribute leaflets in 20 different languages, which will try to dispel myths about the vaccine. they vaccines do not contain animal products or foetal products, they do not affect your fertility, so if you are offered the vaccine, please take it up, because that is what will keep you safe. borisjohnson will set out a road map for easing restrictions on england on monday and has promised a cautious approach that will focus on data and not dates. the latest government figures show 12,057 new infections recorded in the latest 24—hour period. an average of 12,081; new cases were recorded per day in the last week. just over 20 thousand people are in hospital with coronavirus across the uk in the last 2a hours, a54 deaths have been recorded , that's people who died within 28 days of a positive covid test 5)on average, 551 deaths were announced every day in the past week. the total number of people who've died is 119,387. the number of people given their first dose of one of the three approved covid—19 vaccines in the latest 2a hour period is more than a82 thousand. taking the total who've now had theirfirstjab, to nearly 16 and half million people. the number of new cases and deaths may be falling but northern ireland has announced that it is extending its lockdown until april first. some school children will go back to the classroom on march eighth. but for most — school won't return until after the easter holidays. chris page has more. the first minister here at stormont, arlene foster, used a motoring metaphor, actually. she said the devolved government wanted to eventually leave lockdown in the rear—view mirror. in other words, they want to this current period of restrictions to be the last. ministers are stressing that although the coronavirus statistics in this part of the uk are moving in the right direction, while the situation in the health service is still very serious, for example, there are still now more people in hospital with covid—19 than was the case at the peak of the first wave back in spring of last year. so lockdown has been extended from the 5th of march until the 1st of april, that's just before the easter holiday weekend. there will be some relaxations, though, on monday the 8th of march. the number of people allowed to meet outdoors will be increased from six to ten, to two households, some retailers will allowed to operate click and collect services for clothes, for baby equipment, for electrical items. perhaps the most significant change for thousands of families here, pupils in the first three years of primary school will go back to the classroom. a fortnight after that on the 22nd of march, teenagers in the last three years of post primary schools who will be facing important qualifications, they too will go back to face learning. so ministers have been trying to give people a degree of hope, i think, while tempering it with a lot of caution. it's also emerged today that the devolved government will publish its exit strategy on the 1st of march, but that won't include any firm dates for different sectors of the economy reopening. mrs foster saying that the government wants to be driven by data and not by dates. it's called perseverance — and let's hope it lives up to its name. after seven months in space — nasa's rover will attempt to land on the surface of mars in the next hour. only half of the missions to mars have been successful so far. this one — will have to slow from the speed of a bullet to a walking pace if it is going to land safely on the red planet. if it makes it — its mission is to scour a crater that was once a vast lake — to look for signs of past life. our science correspondent rebecca morelle has more. nasa calls it the seven minutes of terror. an approach to mars at 12,000mph, then, just at the right moment... ..a parachute opens, dramatically slowing it down before a complex landing system brings the perseverance rover down to the ground. that's the plan — but only half of mars landings have worked. it is not a guaranteed success. it is the time in the mission with the highest concentrated risk. it's certainly a nailbiter, and they don't call it seven minutes of terror for nothing, because we're certainly waiting to hear back those words, "touchdown confirmed," that's what we're waiting to hear. this mission is all about finding signs of life, the best place to do that is here, the jezero crater. today, it's dry and dusty, but billions of years ago it was a huge lake, and you can clearly see a river running into it. this gives you an idea of what it would have looked like. if we zoom in a bit more, these green areas on the edge of the crater were once beeches on the lake shore, and the hope is any microscopic creatures that once lived there are still preserved. perseverance is the most advanced rover that nasa has ever built, and it's jam—packed with instruments. its robotic arm is equipped with a drill to collect rock samples. so what forms of life could they contain? i am not talking about martian little green men, probably not even fish. we are looking for microbial life, or maybe microbes that have made a little mat or a slime such that you might find on the bottom of a pond. those are the types of things that are likely to... well, they did exist on earth 3.5 billion years ago. the question is, did they exist on mars at the bottom of lakes? for the first time, nasa will also be testing a mini mars helicopter to provide a new bird's—eye view of the planet. and back on the ground, the rover will store some of the rocks — a future mission will bring them back to earth, and some will be heading to the uk. these will be the most precious samples that we have on earth, the most exciting, and scientists around the world will be absolutely fighting and clamouring to study them. this mission provides our best chance to finally answer whether life existed on mars. first, though, nasa needs to get it rover safely down. there are some nerve—racking hours ahead. rebecca morelle, bbc news. australia's prime minister says his country won't be intimidated by facebook, in a row about news coverage on the social media platform. australia is asking tech companies to pay for content which is reposted from other news outlets. now facebook has blocked users in the country from viewing news content. shaimaa khalil reports from sydney. this is what australians woke up to. empty news feeds on their facebook pages, after the platform blocked all local and international media outlets — a dramatic escalation in a continued dispute with the government over paying for news content. the ban did not only target news. it also denied australians access to the pages of many key government agencies, including health departments and the bureau of meteorology. the company later conceded that some of these pages were inadvertently caught in the block and that it will restore them. i do use facebook. it seems to be a catch all, and i can get all of my news in the one spot, so it will really impact me. they're so big and so widely used by australians that they'lljust... people willjust revolt against it. the government was also swift to react. this is an assault on a sovereign nation, it is an assault _ on people's freedom, - and in particular it is an utter abuse of big technology's market . power and control over technology. the prime minister, scott morrison, slammed the social media company's action as arrogant and disappointing. under the proposed legislation, tech giants will be forced to enter into payment negotiations with news outlets over payment for content that appears on their platforms, and if they can't agree, a government arbitrator would get involved. but facebook has criticised the law, saying it doesn't reflect how the internet works, and unfairly penalises it for content it didn't ask for. this fallout is about facebook making a point. many are watching this closely, and the social media giant knows that if it starts paying for news content here in australia, other nations could make similar demands. some experts have described it as anti—democratic and a dangerous turn of events. and while facebook asserts its power and influence with this move, the fear is that it may also do its reputation some serious damage. shaimaa khalil, bbc news, sydney. sir keir starmer has set out his vision for the uk — pledging a "moral crusade" to address inequalities exposed by coronavirus. the labour leader also proposed a new bond for savers, allowing millions to invest in the uk's recovery from the pandemic. our deputy political editor vicki young reports he's trying to inspire a party that has got used to being rejected by voters, in a political landscape dominated by a pandemic. labour members can only watch from a distance as sia keir starmer lays out his vision from an empty room. we can go back to the same insecure and unequal economy that has been so cruelly exposed by the virus. we can seize the moment and go forward to a future that will look utterly unlike the past. he said coronavirus had proved the case for government to play a big role in managing the economy, but working alongside business, not attacking it. if we are honest, for too long labour has failed to realise the only way to deliver social justice and equality is through a strong partnership with businesses. under my leadership, that mindset will change. one new policy idea is a british recovery bond, offering people a savings account with the government. the cash raised would be used to get the country back on its feet after the pandemic. there are people who kept theirjobs who have been able to save money. how does that help those who haven't kept theirjobs, who really are struggling to make ends meet? the bond provides a way for people to invest in the future of their country in a secure way, and releases money for infrastructure projects. obviously for those that haven't been able to save, there are other things i said this morning about universal credit, about the pay for key workers. so it is not either or, it is both. you have been leader for around ten months, how do you think it has gone? a year ago in the leadership race, people were saying to me, "is the labour party even going to exist in the future?" now the question i'm facing is, when will you be ready to win a general election? some are calling on the labour leader to be bolder. he says rightly we cannot go back to normal, but what is normal is not acceptable and we need proper guidance and proper policy to move forward. as of yet we haven't received that. it is a really good start from keir starmer in my view. i get why people are saying we should go further but it sets out how things would be differently if he was prime minister. you can talk about all the policies you like, but if they are not- delivered by a credible leadership that people can believe can - actually deliver them, - then they won't go down well with the public. and do you think he has managed to get that impression across? yes, most definitely. kier starmer says a labour government would actively support the economy. conservatives point out they have just spent almost £300 million doing just that. it shows how difficult it is being distinctive as opposition leader during a national emergency. elections across the uk in may will be the first test of whether voters like what they have heard so far. vicki young, bbc news, westminster. sienna rodgers, is the editor of labour—list, a news website which is supportive of, but independent of, the labour party. shejoins us live from north west london. it was meant to arrive rail the beverage reforms which laid the foundation of the nhs and their welfare state. what we heard about was a saving bond that ultimately helps those people who kept their jobs and were able to put money aside. it jobs and were able to put money aside. . , , ., , ., jobs and were able to put money aside. ., , .,, ., .y jobs and were able to put money aside. , ., .y , aside. it was billed as

were some reports it. aside. it was billed as a policy bit| so there were some reports it was going to be fat. it was not a policy blitz. that's an exaggeration. we have got to the new policies from keir starmer today. have got to the new policies from keir starmertoday. he have got to the new policies from keir starmer today. he repeated the existing labour policies. things like not cutting universal credit in april as people asking the government is planning to do. things like preventing council tax rate is. he said he would protect families by doing those things and he had this to a new policies and the covid—19 recovery bonds. that british bond. the intention was to evoke patriotism, talking about britain. it was also to support and recognise that the argument that labour is making is richie singh axioms all the people who were fortunate enough to save during the pandemic would immediatelyjust go out and spend that. and that will help drive demand in the economy once the economy starts to recover from the covid—19 crisis and they will go out and make that decision. i think labour is saying that is not the case that people are really concerned about security at the moment and a lot of people who save during the pandemic perhaps younger people in their 20s who have never been able to save before. what people in their 20s who have never been able to save before. what about the --eole been able to save before. what about the peeple who _ been able to save before. what about the people who have _ been able to save before. what about the people who have not _ been able to save before. what about the people who have not been - been able to save before. what about the people who have not been able i been able to save before. what aboutj the people who have not been able to save who now have no income and who are really struggling?— are really struggling? completely. there has to _ are really struggling? completely. there has to be _ are really struggling? completely. there has to be a _ are really struggling? completely. there has to be a focus _ are really struggling? completely. there has to be a focus on - are really struggling? completely. there has to be a focus on them. l are really struggling? completely. there has to be a focus on them. i think he did dedicate even more time in his speech to those people and addressing those problems. it'sjust that they were not new policies to address that. i think he is talking about council tax rate is the bap cut for hospitality and leisure and renewing the furlough scheme and all of those things, he was talking about it's just that labour has already announced these policies and this is kind of a problem for the opposition party at the moment. fine opposition party at the moment. one ofthe opposition party at the moment. one of the big problems is to differentiate yourself during a national crisis when you have got the conservatives. they spent nearly £300 billion, standing and spending. they have their themselves enough in order to win back supporters. the main order to win back supporters. jj—ug main challenge, everyone order to win back supporters. jj—ug main challedqe, everyone wants to main challenge, everyone wants to hear about covid—19 and what the new opposition be there is talking about with his policies. i think this was the start and the second stage of keir starmer�*s leadership plan. the first stage was about scrutinising the government and the handling of the government and the handling of the pandemic and sorting of the party internally. and the second stage has just started with a speech today. he will be setting out more policy and my vision for the future but i think this was a sound basis, it was not as exciting as people thought it was going to be but i think it was a good start. thank you so much for— think it was a good start. thank you so much for your _ think it was a good start. thank you so much for your time. _ some people in temporary or privately rented accommodation are living in conditions that are utterly shameful — that's according to a former government adviser on homelessness. a bbc news investigation found people vulnerable to covid — shielding in homes with frequent leaks, widespread damp and even rodents living in a kitchen ceiling. the government says reducing the number of households in temporary accommodation is a priority. rianna croxford reports. see that? terrible. inside some of the uk's most inadequate housing. jesus christ! it's just mentally destroying me, having to stay in such disgusting circumstances. we hear from those shielding... how have you found it being indoors? horrible. i feel trapped. still not fixed. ..stuck inside damp and cramped homes, some even alongside rodents. for six months, we've been following the stories of those vulnerable to coronavirus living in temporary accommodation or privately rented homes. i'm not even able to have my exercise because i'm too worried of catching it. vicky suffers from chronic obstructive pulmonary disease and emphysema. last summer, problems with damp took weeks to be fixed and culminated in this leak from her bedroom ceiling. fixing the doors properly, getting rid of the rats that are the size of cats... theyjust fob us all off, so we feel like we don't exist in a way. the property manager says all repairs have been completed. this is a terrible house. this man lives in the same block. he says there have been holes in the ceiling of his flat since may last year and frequent lea ks. he even showed us footage of rodents living in the ceiling. his repairs have now been made. the number of households in temporary accommodation is nearly double that of ten years ago. half of those living in these homes are children. sarah has multiple sclerosis, which also makes her vulnerable to coronavirus. during the pandemic, she's faced a water leak and damp problems, but remained in the property throughout, despite the council themselves deeming it unsuitable in 2019. i've got a hole in my bathroom in the ceiling, where the light should be. over a year. sometimes i trip going to the bathroom to go to use the toilet, no light. i definitely feel forgotten because i'm still here, 15 months on. the council says it's committed to helping sarah find a new home, but there's a chronic shortage of affordable housing. it's utterly shameful. nobody should be living in those conditions in the united kingdom. dame louise casey has advised labour and conservative government on homelessness. we cannot allow landlords to make money with people living with rodents in their kitchens. i'm just hoping the government watches that and thinks, "yeah, we need to do a betterjob here." the government says reducing the number of households in temporary accommodation is a priority. rianna croxford, bbc news. u—roy, the pioneering reggae and dancehall artist, has died at the age of 78. he was born ewart beckford injones town, jamaica and was also known as daddy u—roy or the originator. he was renowned as a pioneer of the toasting vocal style in reggae and dancehall, and was a key figure in the popular development ofjamaican music in the 1970s. u—roy was awarded the order of distinction by the jamaican government in 2007 for his contribution to music. have a special programme on the mars mission. he will be taking you through this at the minutes of terror. i will be back later with the papers. let us bring you up—to—date with all the sports for a full round up. the opening legs in the last 32 of the europa league are being played this evening with manchester united among the early winners with a 4—0 victory over real sociedad. the match was being played in turin due to covid restrictions, and it seemed to suit united as bruno fernandes grabbed a double, which was added to by marcus rashford with this lovely finish into the bottom corner before danieljames picked up a fourth late on. tottenham cruised through their first leg against austrian side wolfsberger — a match played in budapest. gareth bale set up the first and then scored the second himself lucas moura then scored this brilliant solo goal to make it 3—0 at half time. wolfsberger pulled one back before vinicius scored a fourth for spurs late on. elsewhere in the early games leicester city played out a goalless draw against slavia prague in the czech republic while arsenal who are playing benfica in rome and rangers are away to anderlecht. for all the latest head to the bbc sport website it was a tearful farewell for serena williams at this yea r�*s australian open. she was beaten in straight sets byjapan�*s naomi osaka in the semi—finals. so the 39 year old's bid to equal margaret court's record of 2a grand slam singles titles has to wait a little longer. the loss led to speculation about her future — and whether it could be the last time williams will appear at the tournament in melbourne. i don't know if i would tell anyone. considering how well you played to get to the stage, why do you feel was a just one of those bad days at the office? i was a just one of those bad days at the office? ., �* ~ ., �* ., williams' conquerer osaka, will meet jennifer brady in saturday's final while in the men's final novak djokovic will line up against either daniil medvedev or stefanos tsitsipas on sunday. good evening. as we move out if thursday into friday we are going to see a west east divide developing with our weather. we keep some clear skies across the central and eastern half of the uk and that's going to allow the temperatures to fall away by contrast cloud wind and rain gathers out to the west. yes, low single figures, a chilly start and that's where we'll see the best of the drier weather particularly across eastern england into the afternoon. the rain eventually moving into eastern scotland. it will always be heavy the further west you are, accompanied by gale force gusts of winds as well. so that is going to make it feel pretty miserable, i'm afraid. if you're sat underneath the cloud, the wind and the rain. the best of the dry weather further east and temperatures will peak through friday afternoon between eight and 11 celsius. into the weekend, we keep that west, east divide for saturday. it stays unsettled out to the west but increasingly milder with more sunshine into the east and it'll be a quieter day for all on sunday. take care. hello, welcome to the programme. i am christian fraser in london, and katty kay is in washington. and we are counting down over this next half hour, to what we hope — will be another giant step towards a future manned mission to mars. these are the live pictures from the nasa control room where very shortly a seven month mission to the red planet will come to an end, everyone in that room hoping for the safe touchdown of a new rover on the martian surface. the course —— of course, because of covid, there are less people than normally. we will be keeping an eye on the control room. only half of the missions to mars are successful and this rover, called perseverence, is bigger than anything nasa has tried to land before. to do it safely, the spacecraft that's carrying it will have slowed from the speed of a rifle bullet, to a walking pace in just seven minutes. it is going to be a tense, thrilling half hour. we will bring you all the reaction which will culminate, fingers crossed, with confirmation of a safe landing around five minutes to nine gmt this evening, with pictures hopefully from the surface. the rover will be set down close to a crater, that scientists believe was where an ancient river flowed into a lake. it will spend the next martian year looking for past life. that's a bit shy of two years on earth. on board the rover is a drill to collect rocks, and tools to take samples, which will be stored and returned to earth in a future mission. also on board, and this is very cool, is a small helicopter. the nasa scientists will attempt to fly in the thin martian airfor the first time. our science correspondent rebecca morelle has more. nasa calls it the seven minutes of terror. an approach to mars at 12,000mph, then, just at the right moment... ..a parachute opens, dramatically slowing it down before a complex landing system brings the perseverance rover down to the ground. that's the plan — but only half of mars landings have worked. it is not a guaranteed success. it is the time in the mission with the highest concentrated risk. it's certainly a nailbiter, and they don't call it seven minutes of terror for nothing, because we're certainly waiting to hear back those words, "touchdown confirmed," that's what we're waiting to hear. this mission is all about finding signs of life, the best place to do that is here, the jezero crater. today, it's dry and dusty, but billions of years ago it was a huge lake, and you can clearly see a river running into it. this gives you an idea of what it would have looked like. if we zoom in a bit more, these green areas on the edge of the crater were once beeches on the lake shore, and the hope is any microscopic

did they exist on mars at the bottom of lakes? for the first time, nasa will also be testing a mini mars helicopter to provide a new bird's—eye view of the planet. and back on the ground, the rover will store some of the rocks — a future mission will bring them back to earth, and some will be heading to the uk. these will be the most precious samples that we have on earth, the most exciting, and scientists around the world will be absolutely fighting and clamouring to study them. this mission provides our best chance to finally answer whether life existed on mars. first, though, nasa needs to get it rover safely down. there are some nerve—racking hours ahead. rebecca morelle, bbc news. yeah, and we thought ourjob was nerve—racking. really exciting stuff and we are just minutes away from knowing whether the mission will be succesfull. one person who will be really feeling the tension at this moment is dr lori glaze the planetary science division director at nasa — to you and me that means she's in charge of this mission. she's currently somewhere amongst that group of people we see calling the shots, and she very kindly took a monent out earlier to tell me about the mission. so what's really interesting is, this is going to be the most precise landing we have ever executed. and i will explain that injust a moment, but we landed successfully eight times on the surface of mars. this will be our ninth landing. it will be our fifth rover to land on mars. but this is extremely challenging, and all our prior missions have had much larger landing areas they were trying to hit. but this particular location that we are going has a lot of hazards. so we have really tried to narrow that down. and so what we have done is to bring in some new technologies, you know, we are still coming into the top of the atmosphere the same way, but then we have something that we call our range trigger that is keeping track of how long it's been since we left the spacecraft and since we came into the top of the atmosphere. and that helps us time precisely more precisely when we deploy the parachute. and you're coming in horizontally, but when you deploy the parachute it then starts to fall vertically. and so we timed out so we are more or less of it spot we want to be, and then we have another technology that we are using called terrain relative navigation which is where we are looking, we are taking images all the way down and we are comparing those pictures in real—time autonomously to maps that we have on board the spacecraft, onboard the rover. so i imagine then that every minute of your waking day for the last seven months has been about this moment, and it comes down to these terrifying seven minutes as it descends to the martian surface. what is it like in the nasa control room at that moment? oh, my goodness, that seven minutes of terror is absolutely, you know, it's nail—biting, you are so anxious just watching all the data come in. i was here for the insight landing back in 2018, and it was that same seven minutes of terror. and it'sjust, you know you just can't even imagine how anxious you are. presumably, the things that you are learning in this mission eventually tiers up for that first manned mission. absolutely. yes, there is a lot of what we are going to be working on on this mission is helping us feed forward to human exploration. we are doing a lot of great science on this mission. we will be doing science in the field while we are out there. we are also going to be collecting samples that will be coming back to earth on a future mars sample return mission. but we have lots of technologies that we are demonstrating that are going to help us prepare for human exploration. that terrain relative navigation, that ability to pinpoint land as one of those technologies. we also have an experiment on board called moxie, it's a mars oxygen experiment. it's got more letters in there, but that's basically taking the carbon dioxide atmosphere and converting it into breathable oxygen. with this mission, what we are really focused on is looking for evidence of past life that may have been there about three and half billion years ago, but the time when life emerged on earth. and that's really the key focus of this mission is that astrobiology, trying to understand that environment and how it could support life and whether or not life actually did come to be on mars several billion years ago. what purpose does it serve for us? that's an interesting question. let me think about how you've posed about. i think the implication, really, here isjust the compelling nature of, are we alone in the universe? and that's really, you know, we have yet to identify anywhere else in the universe that life has actually taken hold. but within this location on mars, this particular location where we know that there was standing water present for a long period of time, about three and half billion years ago, and it was sustained long enough that a river flowed in and deposited all its sediments into a river delta. they had all the right conditions. it was warm enough, it was wet enough, the organic molecules were present on mars at that time, just the way they were on earth. and so as we know earth formed about that time, formed life about that time, did it happenjust because we have that environment, was life able to take hold on mars? and to me, that's an incredibly important question to understand whether or not if you have the right ingredients, does thisjust happen, or is there some other key ingredient that we are not aware of? doctor laurie glazer, very important day for her. she was telling me. she must be stressed at the moment. as well as focusing on this, she is already planning and fundraising for the mission in 2026 to go to mars to collect these samples that this rover will be drilling over, we hope, over the next few weeks. at pressure, i mean, if we get it wrong, they record over it, if they get it wrong from it's a multibillion—dollar mistake. i get it wrong from it's a multibillion-dollar mistake. i know. seven years — multibillion-dollar mistake. i know. seven years in

on the conversation that we heard just there with lori about the crater. tell us more about that. because at the moment, it is dry as a bone where the mars rover is landing, but they do hope that this

0k? at 2048 gmt, the descent, so get your clocks ready, ok? at 2048 gmt, the protective error shall, that's the spaceship around the rover, that will enter the mars atmosphere at a speed of around 19,500 km an hour. it takes some slowing down. and as it is hurtling through the atmosphere at those speeds it heats up — with the friction in the upper atmosphere — to temperatures of around 1,300 c. yes, so then at 20:52 — so four minutes into the descent — a 21 metre parachute will deploy, to slow it down, and the heat shield will then be ejected. and that's where the descent vehicle takes over. it is fitted with retrorockets that will gently lower the rover on 7 nylon cords, from about 20m above the ground. when it has slowed down to 2 km/h and the rover gently touches the surface, then the cords will be severed. and at that point 20:55gmt — seven minutes after the descent began — perseverance hopefully will be safely on the martian surface. the descent vehicle known as skycrane will fly off into the sunset, deposit itself some way away, at a safe distance. let's go back to those live pictures from mission control. you can see they are listening in. let's see if we can hear anything.—
