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 m
nasa says it will go ahead and launch the most powerful rocket its ever built. good morning and welcome to bbc news. a manhunt is underway in liverpool after a nine year old girl was shot dead. police say an unknown man is reported to have fired a gun inside a house in the knotty ash area of the city at around ten o clock last night. a man and a woman also suffered gunshot injuries in the attack. ian byrne is the labour mp for liverpool west derby, where this attack happened. he spoke to breakfast earlier this morning. i think devastating is a good way of putting it. we are still going to process what we have heard overnight. it is absolutely devastating that a wholly innocent nine year old young girl has been sadly murdered and i think we are all struggling to process it is a community, in west derby in liverpool and across the country. i think as a moves forward i have heard as much as everybody else, really, we need to hearfrom heard as much as everybody else, really, we
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
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, t
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
