Fuel leak disrupts Nasa preparations for Artemis 1 Moon rocket launch
The space agency confirmed there had been a liquid hydrogen leak but it was unclear whether the launch would be delayed.

Controllers halted the fuelling operation for Artemis 1 on Monday morning, but Nasa said its engineers were rectifying the issue and there was no word on whether it would cause delays to take-off from the Kennedy Space Centre in Cape Canaveral, Florida.
Nasa said: “Teams continue to troubleshoot a liquid hydrogen leak at the mating interface with the core stage.
“After manually chilling down the liquid hydrogen as part of troubleshooting efforts, they are in fast fill operations.”
Similar leaks hindered Nasa’s countdown tests in April and June.
Managers said they would not know for sure whether the leaks had been resolved until attempting to load the rocket’s tanks with nearly one million gallons of super-cold fuel later on Monday, according to the Associated Press.
The uncrewed flight marks the next chapter in putting humans back on the Moon, and is the first in Nasa’s Artemis programme.
There will be astronauts on board for subsequent missions, with the first crewed flight into space scheduled for 2024.
Nasa expects the first Artemis astronauts to land on the Moon in 2025.
The Artemis 1 mission will see the first launch of the new 322ft (98m) tall Space Launch System (SLS) rocket, which the agency says is the world’s most powerful rocket to date.
It will take the Orion capsule, powered by the Airbus-built European Service Module (ESM), into the Moon’s orbit.
Airbus engineer Sian Cleaver is industrial manager for the ESM, and as a child dreamt about being involved in human spaceflight before getting a master’s degree in physics and astronomy from Durham University.
She told the PA news agency: “I’m ridiculously excited, and I think everybody on the team is.
“There’s years and years of a labour of love into this project.
“This is the first time that we will have seen one of our European service modules flying in space and going to the Moon.
“I think a lot of us couldn’t quite believe it – we’ve now got the go for launch.
“Now, I think it’s really sinking in that this is reality, this is happening, and it’s going to really start this whole new chapter of space exploration, and going to the Moon.
“We’re on the brink of something really exciting now.”
Ms Cleaver said the last time humans went to the Moon, some 50 years ago, it was about proving that it could be done, whereas the new mission is about proving people can go there for longer and more sustainably.
It will also assess whether some infrastructure can be built on and around the Moon, allowing humans to survive on another planetary body.
Now in her 30s, Ms Cleaver first visited the Kennedy Space Centre in Florida, where the launch has been given a window from 1.33pm (BST) on Monday, when she was just eight years old.
Her role in building the ESM involved making sure that all of the equipment and the subsystems came together at exactly the right time.
Speaking of attending the launch, she said: “I am so excited to be there.
“It is going to be, for me personally, a really special moment to be back there after so long. And now to actually work in the space industry, I still haven’t quite got my head around it really, that I’ve achieved something that I wanted to do since I was 15 or so.”
She added: “It’s pretty amazing that, even at this stage of my career – 10 years into Airbus – that I’m working on essentially my dream mission.”
The mission duration is 42 days, 3 hours, 20 minutes, and in total the capsule will travel 1.3 million miles, before splashing down on October 10.
The UK is part of the Artemis programme, making contributions to the Lunar Gateway – a space station currently in development with the European Space Agency – working alongside the US, Europe, Canada and Japan.
The Artemis mission will be tracked in the UK from Goonhilly Earth Station in Cornwall.
Libby Jackson, exploration science manager at the UK Space Agency, said: “The first launch of the Artemis 1 SLS rocket is an important step for the global space community as we prepare to return humans to the Moon.
“The Artemis programme marks the next chapter of human space exploration and we look forward to continued involvement as it comes to life.”
