for the first time in nearly a decade, plans to send astronauts into space from american soil. spacex has played a key role in the mission. now everyone is praying the weather will play. jan o'brien has more. bad weather has battered cape canaveral, adding to the suspicions of testing during the pandemic. nasa says the mission is so far a go for lunch. this is a unique opportunity to bring all of america together. at one moment in time, and say look at how bright the future is. that is what this launch is all about. it is also about turning space into a commercial enterprise. the crew dragon capsule developed by spacex is part of a

multibillion—dollar deal with nasa to provide material to the iss. the partnership will not only free up an asset to focus on big missions like getting to mars, it could define the next era of space expiration. we are proving our business model, a public—private partnership business model that ultimately will enable us to go to the moon this time and sustainably. in other words, we will go to the moon to stay. bob and doug have been spending time in quarantine and have been also testing the system. astronauts arrived at the kennedy space center on a rather more mundane aeroplane to conduct a final dress rehearsal for the lunch. i happen to have been one of the four astronauts that landed

here almost 90 years ago to close out the space shuttle programme. so it is incredibly humbling to be here to start at the next phase. —— nine years ago. nasa and spacex can cancel the mission up to 45 seconds before the launch. but assuming all goes to plan, some of the astronauts will have up to 114 days before the crew dragon solar power sets down. there will also have to be another good weather window for a safe splashdown off of the coast of florida. normally, a launch of this significance would've tracked hundreds of thousands of visitors. but because of the coronavirus, everybody to wants to watch online. that probably will not stop crowds gathering on the recently reopened beaches in the hope of glimpsing this historic moment. now on bbc news: our world.

this is the story ofjust a few of the people making sacrifices to save lives. i follow their efforts through the peak of the epidemic in spain. until the lockdown begins to be lifted. spain is under one of strictest lockdowns in the world. people are only allowed to go out on their own to buy food or medicine and walk their dogs. it is forbidden for children to go outside.

in just a single week, the number of covid infections has tripled. and hospitals across spain are struggling. the uk has started its own lockdown. i've travelled the world making documentaries. now, for the first time, i'm making a film about my own country from my home in london. la mancha, a region two hours south of madrid has been hard—hit by the virus. i've make contact with a nurse, loli.

loli's husband, jesus, is supporting her.

loli and jesus have two children. when the crisis started, she took them to live at her sisters‘. she hasn't seen them for two weeks but today she's going to visit them to give them their schoolwork.

in madrid, the army has turned a convention centre into spain's largest medical facility injust ten days. they have even laid medicinal oxygen pipes under the floor. it is now treating hundreds of covid—i9 patients. blanca's a gp who has volunteered to work at this new hospital.

the level of police to enforce this lockdown is unprecedented. there are checkpoints on major roads, and aerial surveillance. her cousin has been in the hospital with the virus. first, they need to collect their ppe — personal protective equipment. when the crisis started, the central government took charge of sourcing ppe, but some local authorities say they couldn't do it quick enough.

in madrid alone, hospitals need 200,000 masks every day. a couple of hours south of madrid is this small village. a group of people have volunteered to make ppe for loli's hospital. esperanca is one of them. clinical fabric is scarce and the red cross is distributing blankets to operating theatres. this town has a population of 8,700. nearly all of the women in the village have joined the effort.

esperanca's 58—year—old brother—in—law is in intensive care with covid—i9. this evening, her son, jose luis, is volunteering to disinfect the village.

spraying with disinfectant is happening all across spain. the army has been brought in to disinfect the streets, hospitals, and care homes. at home, esperanca keeps sewing. a few days later, her 89—year—old mother gets the virus. esperanca has been helping care for her mum so she has to destroy the masks in case they're contaminated.

esperanca and her family have decided that their mother won't be going into hospital. esperanca and her sister have moved in with their mother.

a few days later, esperanca's mother dies. esperanca has contracted the virus too but for now is well enough to stay home. la mancha has had more than 10,000 cases of the virus and loli is working 12—hour shifts at the hospital. undertakers are preparing

for a huge numbers of deaths. there already have been 15,000. indoor ice rinks have been turned into mortuaries, and families grieve at drive—through funerals. shortly after infections in madrid reach a thousand a day, cases of the virus start to increase in barcelona. marius is a nurse who volunteers to deliver ppe. he's on his way to a nursing home outside the city. marius is a nurse who volunteers to deliver ppe. he's on his way to a nursing home outside the city.

marius is met by the manager. more than 18,300 people have died of coronavirus in nursing homes. that is nearly 70% of all the deaths in spain. when the army was disinfecting care homes, they found elderly people who had been abandoned and some were found dead. the prosecutor's office is investigating more than 140 care

homes for alleged criminal actions. bells toll it's easter. for the first time, the bishop in majorca is blessing an empty cathedral. this is loli's first easter away from her children.

the death toll is finally starting to go down, but madrid's field hospital is still working at full capacity. blanca and her colleagues work hard to keep morale up.

many of loli's colleagues have caught the virus. spain has the highest percentage of infected healthcare workers in the world, with at least 15,000 cases. -- 50,000.

by the end of april, the number of patients admitted to hospital is going down. this icu team is trying to come to terms with what they've been through.

before the crisis, spain had 11,500 intensive care beds, by the end, icus have treated nearly 11,500 patients. ventilators have been key to expanding the number of icu beds.

eduardo fernandez and his association of entrepreneurs have sourced and donated over 110 ventilators to hospitals all over spain.

i asked the spanish government about what people had told me in this film. they said ppe and other forms of medical supplies were provided in the regions at the beginning of the crisis. today, children under 1a are allowed out for the first time. spain is the only country in europe where children were not allowed out during lockdown. loli's children are going for a walk with her sister.

children are still only allowed out for one hour each day and only with the one adult. madrid's field hospital has closed, but the oxygen pipes haven't been dismantled yet, just in case. blanca is on her way back to her gp practice.

a week later, adults are allowed out at specific times to exercise. loli has finally been tested, the result is negative stop sue is back with her colleagues, nursing non—covid patients. now she can bring her children back home. and loli's parents have come up for the first time to see their grandchildren. piano and violin plays

hello there. there is plenty of dry and very warm weather in the forecast for the next few days. now, during tuesday, the very highest temperatures were found across eastern and southern parts of the uk, 27 degrees to the west of london. it was a bit cooler further north and west — not an awful lot cooler — but actually as we go through the next few days, we're going to see this area of high pressure, which is really

dominating the scene, shifting a little further eastwards. now, the winds around the high pressure flow in a clockwise direction. so as the high shift eastwards, that will allow us to waft warm air northwards across just about all parts of the uk. but we start wednesday morning with the very mildest conditions across the south — 13, 1a degrees in cardiff and in london. not quite as mild further north. but as we go through the day ahead, we're expecting lots of fine weather, some spells of sunshine, a bit of patchy cloud towards the south and east of england, and certainly more cloud into northern ireland and scotland. and that cloud mayjust start to fringe some patchy rain in across the far west. those temperatures getting up to around 17 degrees there in glasgow. once again, 2a or 25 across parts of south wales, central and southern parts of england. now, as we go through wednesday night into thursday, we will see some outbreaks of rain pushing across the northern half of scotland, a weak frontal system pushing through. further south, it's dry with some clear spells on what will be a mild night for most — lows of six to 12 degrees. any early rain across scotland or nort—heast england will clear very quickly on thursday. and then, as you can see, increasing amounts of sunshine. bit of patchy cloud here and there, yes, but largely sunny skies.

and at this stage, i think the highest temperatures will be found across western areas. so liverpool, cardiff, 25 degrees, but glasgow up to 22. a bit coolerfor some north sea coasts. now, as we get into friday, remember, when you look at our maps and you don't see cloud, that means we're expecting sunshine. a lot of blue sky overhead on friday. again, those temperatures, 2a, 25, 26 degrees. parts of south—west scotland getting into the middle 20s. still a bit cooler for some of those north sea coasts with a flow of air off the sea, but as we head into the weekend, high pressure does remain dominant. it should fend off this frontal system. yes, we mightjust see a little bit of rain fringing into the far north—west of scotland at times, but generally speaking, it's a dry weekend. and widely, it will be very warm, with those temperatures into the 20s.
