this is bbc news with the latest headlines for viewers in the uk and around the world. the launch of nasa's big new moon rocket is facing a potentially lengthy delay. russia's main pipeline transporting gas to europe will stay shut. moscow blames maintenance problems. thousands of people have paid their last respects to mikhail gorbachev — the man who brought the cold war to an end. the death of mikhail gorbachev really does mark the end of an extraordinary era in history, a rare period when russia was opening up to the world. and a warning of a rise in water—borne diseases in pakistan, as the country struggles to cope with the aftermath of devastating monsoon floods.

hello and welcome if you're watching in the uk or around the world. nasa tried and failed again on saturday to get its space launch system vehicle to lift off from florida's kennedy space center. the countdown had to be halted because of a fuel leak — the second postponement in a week. the artemis programme aims to return humans to the moon in 2025, but the nasa team have suggested that there may now be a significant delay to the project. our science editor, rebecca morelle, gave us the latest from kennedy space center, in florida. there is a real sense of disappointment here

but the problems started early on, and when the rocket was being fuelled, a large hydrogen leak was spotted, and this is not a good thing. the team tried to fix it three times but their troubleshooting did not work and the loach was stopped. over the last few hours, they have been poring over the data to find out what went wrong and they have announced the rocket will need significant repair work. this mission was nasa's first return to the moon in more than 50 years on the moon in more than 50 years on the idea was that the rocket was going to launch a small spacecraft called orion, it is perched at the top of the rocket, and take it orbiting around the moon before it turned —— returned to earth. it was to take five or six weeks. it was a test flight so no people were said to be on board but for the next mission, astronauts were going to join the ride and go in orbit around

the moon but the ultimate aim was to land astronauts on the moon and nasa wanted the first woman and the first person of colour walking on the earth's surface. this will take a bit longer because now the first step is getting this rocket off the ground. it is important to remember that this is a new rocket. rockets are incredibly complex machines and this is the one that is the most powerful nasa has ever built so they are learning about it, they are learning about it with every attempt they are taking to get this off the ground. so setbacks are common. but it does appear that the ambitions of nasa to get back to the moon are going to be delayed by a little while. here's the artemis mission manager describing the options for repairing the rocket. the first option was to simply remake the umbilical pain, hoping that the soft goods would seal the

leak up but our confidence level, given the size of the leak that we saw today was barely low that it would solve the problem. the team lead towards a removal and replacement of the soft goods and disconnect, and the options were basically do it at the pad or do it backin basically do it at the pad or do it back in the vehicle assembly building. either of those options do not preserve our ability to fly before the end of the launch period which expires on the sixth. leroy chiao is a former nasa astronaut and commander of the international space station and joins us from houston. thank you for coming on the programme. how frustrating is this, then? ~ , , , programme. how frustrating is this, then? , , , ., then? well, this brings me back to m first then? well, this brings me back to my first days _ then? well, this brings me back to my first days and _ then? well, this brings me back to my first days and nasa _ then? well, this brings me back to my first days and nasa in - then? well, this brings me back to my first days and nasa in the - then? well, this brings me back to my first days and nasa in the early| my first days and nasa in the early 19905 my first days and nasa in the early 1990s when we were having all kind of hydrogen leakage issues with the space shuttle and it seemed we would never be able to launch shuttles again. we had delay after delay

after different vehicles and we finally got that salt and i am sure the technical team here will get these problems are solved. this is a new leak that had been seen previously, in other words the small leaks seen on monday attempt were from a different area. just leaks seen on monday attempt were from a different area.— from a different area. just on that oint, i from a different area. just on that point. i can't _ from a different area. just on that point, i can't work _ from a different area. just on that point, i can't work out _ from a different area. just on that point, i can't work out whether i from a different area. just on that i point, i can't work out whether that is a good thing or a bad thing, you don't want leaks all over the place, i suppose, but i suppose it is good news they fixed the first leak but i doesn't seem great. i news they fixed the first leak but i doesn't seem great.— news they fixed the first leak but i doesn't seem great. i should clarify that, monday _ doesn't seem great. i should clarify that, monday we _ doesn't seem great. i should clarify that, monday we thought _ doesn't seem great. i should clarify that, monday we thought there - doesn't seem great. i should clarifyi that, monday we thought there was doesn't seem great. i should clarify l that, monday we thought there was a leak, it turned out there was a crack in the installation, the cold metal allowed condensation and ice to form. initially, they thought it was a hydrogen leak so i should correct myself on that, but yes, you are right, you don't want multiple leaks but, you know, this one cropped up unexpectedly and in the words of the minish —— mission

management team, the options are to try and repair at the pad or roll back, rolling back would be a bigger delay than repairing at the pad but nasa has not officially made a decision one way or the other yet. interesting to hear you say similar problems with the hydrogen going back a long time, it is difficult stuff to deal with. what do you make of the options now going forward? so, liquid hydrogen is that trickiest propellant to deal with, it is cryo janet, it likes to leak a lot, but the options, going forward, are to go ahead and fix this problem and try to fly as soon as we can. there are other constraints of course, the availability of the range at the launch facility and so i think we are looking at, it was said earlier, where we are going to be in the next week or so, it will be in the next week or so, it will be in the next week or so, it will be in the next several weeks or if we have to roll back it will be a

month or so. this is a new vehicle and these things happen, unfortunately. it is using heritage hardware, the space shuttle main engine is very well understood, it is using the backbone, if you will, of the external tank of the shuttle, also well understood, so i am a little surprised that there have been the issues that have been but, you know, we have to deal with it and flight when we are ready. lastly, and briefly, we want to try to get humans back on the moon as soon as possible is the aim of nasa, 2025, what is your betting on whether that actually happens? i don't think we will get humans back on the surface of the moon by 2025, i think maybe by then we can get an apollo eight type mission that launches astronauts into orbit around the mode but not land, and the reason i say that is because we do not have a lander yet. we have

contracts with companies like spacex to help nasa built a lander but even that programme is not fully funded and so, you know, we are going to have to wait and see when we might actually like humans. on the other side of that card is there are a lot of commercial companies working on space endeavours, including spacex, which is helping nasa and has a contract to help them land a spaceship based on starship technology, it is possible we could do a collaborative effort with nasa and spacex as they are already working together.— and spacex as they are already working together. long and short of it is more delays _ working together. long and short of it is more delays ahead. _ working together. long and short of it is more delays ahead. thank- working together. long and short of it is more delays ahead. thank you | it is more delays ahead. thank you for sparing the time and coming on the programme, thank you. the main pipeline bringing gas from russia to europe has remained shut after what was intended to be a three—day closure. russian state energy firm gazprom said it had found an oil leak in a turbine on nord stream 1, meaning it would be closed indefinitely. the pipeline was initially shut for what gazprom described

as maintenance work. the extended closure is likely to put further pressure on gas prices. already it's feared that people across europe will not be able to afford the cost of heating this winter. our correspondent jessica parker in brussels explained the anxiety being faced in the eu. well, look, every day that there is less gas flowing into europe, the greater the squeeze on supply that threatens to hit people's pockets, the economy as well, notjust here but in the uk as well. now, the russian pipeline operator has said it is an oil leak that has led to this prolonged closure. they do not believe that here, and they weren't taken by surprise by last night's announcement. eu countries have spent summer trying to build up their gas reserves but i think the last 2a hours, there really has been an added sense of urgency, governments looking at ways to try and protect people, protect businesses from the worst effects of this energy crisis. energy ministers are meeting here in brussels next week to look at ideas around market reform, gas price caps, but not

everybody is of one mind. the eu knew that this winter would be a collective tests of its resolve to support ukraine. it feels like that test is already under way and it is only early september. will kennedy is executive editor for energy at bloomberg. he says this move will speed up the energy crisis in europe. it is worth saying that the pipeline was operating at vastly reduced levels already. it can carry about a third of russia's usual gas supply to europe but it was operating at just 20% of what it should be. but that 20% was useful to fill up gas storage before winter and now that is not going to happen, so it is going to be harder to fill up our gas storage, it is going to raise the risk of energy shortages this winter, and it really sharpens the dilemma for european politicians as they plan for what could be a very difficult situation over the next few months. we have reduced gas consumption, and although it is worth saying that has come at the expense of closing many factories, high—energy using factories like metal smelters

and fertiliser plants which will have an impact on the european economy. and we have also managed to increase our imports of gas by tanker, especially from the united states. but it is likely, especially if it is cold this winter, there is still going to be a bit of a gap, and if it is very cold and we have that gap in demand with supply it is hard to see how this is going to be filled with no gas coming through nord stream at all. the funeral has taken place of mikhail gorbachev, the last president of the soviet union, who helped bring the cold war to a peaceful end. he died on tuesday at the age of 91. russian president vladimir putin did not attend due to what he described as constraints on his schedule. our russia editor steve rosenberg reports. in the columned hall of moscow's house of unions, a last farewell to the man who changed the world.

mikhail gorbachev had let the iron curtain crumble, he had ended the cold war but saw his own country, the soviet union, fall apart. there was a guard of honour but no state funeral — a sign that vladimir putin's kremlin has little interest in honouring mr gorbachev�*s legacy. president putin didn't even come today. many russians blame gorbachev for the collapse of their superpower. but out on the streets, muscovites, young and old, were queueing up to pay their respects. gorbachev had given many here their first taste of freedom and democracy. in today's russia, both those things are under attack. these people came to gorbachev to say... ..to thank him, to say, "thank you, mr gorbachev. "you gave us a chance,

and we lost this chance." the end of an era. we hear that phrase so often, its meaning has almost been diluted. but the death of mikhail gorbachev really does mark the end of an extraordinary era in history, a rare period when russia was opening up to the world, when people here were being given freedoms, and when east and west pledged to live together in peace. as mr gorbachev�*s coffin was carried from the building, a final round of applause... ..before his finaljourney. most soviet leaders were buried in red square, but for the last leader of the soviet union, his final resting place is this moscow cemetery. mikhail gorbachev�*s wish was to be buried beside his wife, raisa. he loved power but

he loved her more. steve rosenberg, bbc news, moscow. the international atomic energy agency says ukraine's zaporizhzhia nuclear plant has again lost connection to its last remaining external power line. the head of the agency has said that military activity has violated the physical integrity of the plant several times. zaporizhzhia in southern ukraine is europe's largest nuclear plant. it was occupied by russia soon after it invaded ukraine in february. there's been heavy fighting close by and the plant has been rocked by shelling. six members of the iaea team remain at the plant and have carried out a second day of inspections. our security correspondent frank gardner is in zaporizhzhia and told us more about the comment by the iaea that the plant's physical intergity has been violated several times.

well, what it means is that it's taken incoming shell and mortar and artillery fire. nobody knows exactly for certain by whom. the russians say it wasn't them, it was the ukrainians. the ukrainians say vice versa. but that incoming fire has affected potentially it can affect the electricity power line. so there was an interruption to the power supply previously. backup generators kicked in. but the power supply is the key here because it's not just the physical danger from shells coming in. and remember that this is a power plant right in the middle of a war zone. it's the threat to the power supply that keeps the reactors cool. interrupt that for long period of time and there is the risk of overheating and the accidental release of radiation. so i'm speaking to you now from just outside a medical facility

on the edge of zaporizhzhia in southern town in southern ukraine. and they're going to be handing out potassium iodide tablets here as a precaution to the population against any radiation poisoning. nobody�*s suggesting it's about to happen. it's a precaution. you take it for 2h hours and it helps protect the thyroid gland from radiation poisoning. the fact that the monitors are in there now essentially acts as the eyes and ears of the world, of the international community on what is going on inside that nuclear facility. because up until now, nobody has known for certain the ukrainian technicians have been keeping it going. the ukrainian technicians have been keeping it going, the russian military are in control, but nobody�*s been getting a really clear idea of it. that's changed in the last 48 hours. that's a plus. but it's not a guarantee against future attacks because, as i say, it's the middle of a war zone. and rafael grossi, the director general of the international atomic energy agency, is quite sanguine about this. he's saying, look, great that we've got them in there,

but there is still the possibility of future violations, of physical violations. in other words, attacks, shells coming in. really, a nuclear plant is not the place to be firing mortars and rockets and artillery. this plant is relatively well protected. it's much more modern than the chernobyl one that blew up in 1986. it's got protective shields around the reactors. but the biggest threat is really the interruption of the electricity supply. and ukraine has been accusing russia of doing what it calls nuclear blackmail, of worrying the world and the west in particular, that there is a risk that there could be a huge, great, big accident. nobody�*s talking about a mushroom cloud of an explosion, but the accidental release of radiation. now it's time for the latest sports news with lizzie greenwood hughes. starting with football, and it has been a busy day in the english premier league with eight games. defending champions manchester city missed out on going top, held to a 1—1 draw with aston villa, erling haaland opened the scoring for city, and the leon bailey got a point that takes aston villa out

of the relegation zone. elsewhere, and out of sorts liverpool were held to a goalless draw by city rivals everton with an outstanding performance from goalkeeperjordan pickford. there were wins for tottenham and chelsea. brentford had a 5—2 victory, newcastle and crystal palace was goalless, nottingham forest were 2—0 up at half—time, but three second—half goals have given bournemouth a 3—2 victory. and wolves had their first league win of the season, 1—0 over southampton. england have qualified for the 2023 women's world cup with a 2—0 victory away to austria. eight times world cup winners germany have also guaranteed their place in next year's tournament by beating turkey 3—0. england boss sarina wiegman was pleased to see the lionesses performing at their best, after a break since becoming european champions in july. again, a hard game, but coming out of the euros, not having that much rest, some of the players were in the champions league, other players didn't play many minutes, i think austria had the same problem a little bit, but i think after all that,

i am very proud of the team that we came out like this and we just won the game. it looks so easy but i think it was hard. max verstappen delighted his fans to claim pole for his home race — the dutch grand prix, for the second year in a row. sergio perez crashed his red bull on the final corner leaving britain's lewis hamilton unable to improve on fourth on the grid. i'm really happy that the car finally felt alive this weekend. to be going through 01 and q2 and only be a tenth behind a red bull was a great feeling and it really gave me a lot of hope that i could fight for the front row. but obviously the yellow flag at the end was a bit unfortunate but that's motor racing. and that's all the sport for now. the medical charity, medecins sans frontieres, says a shortage of clean drinking water in pakistan is causing an increase in water—borne diseases in areas hit by the country's worst—ever floods. 33 million people have been

affected by the disaster. officials in the southern province of sindh say another quarter of a million people are at risk of more floods, as water levels rose sharply again. well, earlier, ispoke to the former chief of operations of the united nations emergency coordination centre in the international response to the 2005 kashmir earthquake in pakistan, andrew macleod. i asked him first about the how capable the infrastructure and army are in response to the floods. the pakistan military has a great capacity to respond, they learnt a lot from the 2005 earthquake and responded well then and military structures are very good at responding quicker than many civilian structures can. but we have got to remember this is on massive scale that no country could respond to on their own, not the uk, not the united states. pakistan will absolutely need assistance. and remember this, floods are the worst type of natural disaster to respond

to because they take so long. an earthquake is 30 or 90 seconds, a fire passes through an area, a volcano may erupt for a week or so, but floods can go on for months and you cannot get the recovery until the emergency is over so floods are the most difficult, this is covering a lot of terrain, the pakistan military can respond very well but no country can do this on their own and people should help pakistan. that is an interesting point but that is obvious and simple but we have not heard much of that analysis that have difficulty in responding to flooding is because the time pressure. what are the risks, particularly with water and with flooding? well, you get a lot of unusual risks, one of which is the need for snake anti venom. snake swims in floods. you get a lot of snake bites and you get waterborne diseases

and you also get catastrophic destruction of the logistics chains. during the flood and immeidately afterwards, you have got to do a lot by air and by boat, many of the bridges and roads are destroyed or have become completely buggy and water is such a destructive chemical, you know, we call it h20, we call it water, it is hydrogen dioxide, it kills people, it destroys roads and bridges so it is a very difficult context to respond to. waterborne diseases, absolutely, snake bites, absolutely, and then we are coming towards the preparation time for winter. september and october is normally the time people in pakistan people prepare for the winters. we have to be prepared to help pakistan not just for the flood in the immediate relief but we have to help them all the way through winter, three january and february. we have seen in pakistan this

extraordinary extreme weather and the links to climate change, too. without a doubt. there is increased humidity in the ad that increases rain and the other more worrying thing is the melting of the permafrost and the glacier high on our chains. for people who think this doesn't matter to them, if you are going to go to skiing holiday in switzerland in february, the ski lift is bolted in to the permafrost that is starting to melt. so, climate change is having a real impact not only for people in pakistan but for people like us on our holidays. going back to that call for international help that you made, saying that no country could do this on their own, they need that response, there are fund—raising efforts and appeals already under way, is this something that pakistan is just going to have to get used to responding in this way or is there anything preventative that can be done? well, a bit of both. one of the things we did

after the 2005 earthquake is we set up a national disaster management authority, so that has been a great step forward, that pakistan realises that natural disasters are a recurring event in their country, earthquakes, floods, they will happen quite a lot. there are preventative mechanisms that you can put in place by getting your community is ready for any cash and inevitable disaster, but australia doesn't go that well for bushfires, there are preventative mechanisms that you can put in place by getting your communities ready for an inevitable disaster, but australia doesn't go that well for bushfires, the united states doesn't do it well for floods, look at the rail system in the uk every time there is a weather event so if we in the wealthy countries cannot prepare for disasters, how can we expect pakistan to? the us senator lindsey graham has told the bbc that the fbi investigation into classified documents found at donald trump's mar—a—lago home last month could "create a major problem in the united states". he's been speaking to

hardtalk�*s stephen sackur. what i am saying is that the department ofjustice and the fbi, when it comes to trump, there seems to be no rules amongst some. if you are going to prosecute the likely nominee in 2024, the former president for mis—selling classified classic —— information. if he has done more, he will be held accountable. if you give clinton a pass and you go after trump forjust mishandling classified information, you will have a real problem in america, and i hope we have legal system we all can trust, i am not asking to the investigation against president trump, i am asking the media not to try him before we get all the information. mr trump, who is being investigated over his handling of classified records, denies any wrongdoing. you can watch the full hard talk programme on the news channel

and on bbc world news on sunday. you're watching bbc news. now it's time for a look at the weather with alina. we had to pause for a bit of housekeeping to say goodbye to our viewers watching around the world but if you are still with us, it is time for the weather. hello. the second half of this weekend continues with this mixed picture across the uk, warm sunshine for some, heavy rain for others, the heavy rain tied in with this slow—moving area of low pressure which stays with us as we go into the new working week. and we start sunday with some heavy rain initially across northern ireland and northern england, pushing its way north and eastwards across scotland, not reaching the northern isles until much later in the day. the showers elsewhere will fade through the morning, some spells of sunshine, but likely to see some heavy showers

developing across south—west england through the afternoon. showers are likely to crop up almost anywhere, could be heavy and thundery where we do see them but quite well scattered, east anglia and south—east england staying mainly dry. quite a breezy day, particularly for irish sea coasts where we could see stronger gusts for a time, but a warm day for most of us, especially across east anglia and south—east england where we see the best of the sunshine, 24, 25, maybe even 26 celsius here, and the low to mid 20 celsius for many of us. for sunday night, we see another band of heavy rain pushing up from the south, and that is likely to affect a large swathe of the uk. heaviest across england and wales, perhaps not reaching the far north of scotland until much later in the night. once again, it is a warm and muggy night with temperatures not much lower than 14 or 15 celsius. so, then, we start the new week still with this area of low pressure to the west of the uk, it is going nowhere fast. notice the squeeze on the isobars, so still some stronger gusts of wind, particularly across south—west england and for irish sea coasts, and further showers as well on monday.

the rain initially heavy across northern england and scotland through the morning, it will be easing away, and actually behind it, a good deal of sunshine but they will be some showers cropping up, and where we see them, again they could be heavy and thundery, somewhat hit and miss, some will have a largely dry and warm day, again temperatures in the low if not made to 20 celsius as we start the new working week. this area of low pressure really isn't going to go away through much of next week, slow—moving eastwards across the uk and it is going to bring showers or longer spells of rain on most days, some much—needed rain, but we need to keep an eye on the south of england because we could see some very heavy rain here for a time through the week. one way or another, most of us are going to see some showers or some longer spells of rain in the week ahead, and the temperatures will be slowly coming down, too. bye— bye.

hello and welcome to our look ahead to what the papers will be bringing us tomorrow. with me are benedicte paviot from france 24 and eleanor langford from politics home. tomorrow's front pages. writing in the sunday express borisjohnson calls on his mps to end in—fighting and back his sucessor, who'll be announced on monday. the observer says front runner liz truss is being warned not to pack her cabinet with borisjohnson loyalists if she wins the leadership race. truss tells the telegraph she'll do away with sticking plasters on the ecomomy and the energy crisis. the front page picture is of our bbc colleague george alagiah, speaking to the paper about his cancer. the sunday times reports on president zelensky saying the energy crisis is a price worth paying to avoid world war.
