Artemis 1

It was not immediately clear if space agency will be able to make fixes in time to meet next backup launch date of Monday.

Officials said they had identified that problem as a faulty sensor rather than an issue with the cooling system or engine itself. “This is part of the space business,” he said. It was the second time in five days that technical issues had kept the spacecraft on the launchpad.

[Space](https://www.theguardian.com/science/space) Center waited until late in the countdown to scrub the liftoff after the failure of several workarounds to try to plug the leak of liquid hydrogen as it was being pumped into the core stage of the Space Launch System (SLS) rocket. [Nasa](https://www.theguardian.com/science/nasa) officials said the next attempt would be delayed until at least the end of September.

NASA called off a second attempt to conduct the inaugural launch of the SLS Sept. 3 after failing to resolve a liquid hydrogen leak during fueling.

The agency went into the second launch attempt with more confidence about a launch based on the experience from the earlier launch attempt and the previous rehearsals. Engineers later concluded the anomalously high temperature was the result of a faulty sensor and that other data showed the engine had, in fact, cooled to the proper temperature. [NASA scrubbed its first attempt to launch the rocket Aug. Controllers noticed a leak in a quick-disconnect fitting for a liquid hydrogen line into the core stage of the SLS shortly after fueling of the core stage started. A second technique involved stopping hydrogen flow and closing a valve, then using pressure from helium in ground systems to force the fitting back into place. 3 after failing to resolve a liquid hydrogen leak during fueling of the rocket, potentially delaying the mission until October.

CAPE CANAVERAL, Fla. — NASA called off the second attempt to launch an ambitious test flight of its new moon rocket on Saturday (Sept.

Next, engineers tried to repressurize it with helium, and then returned to the warm-and-chill method to stop the leak. — NASA called off the second attempt to launch an ambitious test flight of its new moon rocket on Saturday (Sept. 3), this time because of a stubborn leak that delayed fueling.

[Felix & Paul Studios](https://deadline.com/tag/felix-paul-studios/) are planning to livestream the unmanned launch of the first vehicle on Aug. The launch viewing will be in an immersive 360° format and accessible in Virtual Reality on Meta Quest, on Facebook 360, and in a worldwide coalition of domes and planetariums where space fans can gather for a mobile experience. It will mark the first test flight of the agency’s Space Launch System (SLS) and the complete Orion spacecraft that will someday carry a manned crew. A planned launch for the rocket was scrubbed after temperature concerns arose about one of its four main engines. UPDATE: NASA said it will try again this Saturday to launch its Artemis mission to the moon. PREVIOUSLY, August 25: To the moon, Alice.

However, conflicts with other missions scheduled to launch from Cape Canaveral could push the launch back to October. The launch team tried three times to troubleshoot the issue and start the LH2 flowing again, but each time the leak returned. The leak first cropped up as NASA began loading the liquid hydrogen propellant at around 7:15 a.m.

A fuel leak that thwarted NASA's second attempt to launch its new Artemis 1 moon rocket on Saturday (Sept. 3) will likely take weeks to fix.

Follow us [@Spacedotcom](http://twitter.com/spacedotcom) (opens in new tab), Analyses soon traced that issue to a faulty temperature sensor, and the team decided to [push ahead with another try on Saturday](https://www.space.com/artemis-1-moon-mission-launch-september-3). It's unclear at the moment if the mission team plans to seek such a waiver. Ten tiny cubesats are flying on Artemis 1, to conduct a variety of science work and test various technologies. The leak occurred after a brief "inadvertent" overpressurization of the fuel line that was three times the acceptable pressure, said Mike Sarafin, NASA's Artemis 1 mission manager. But they stressed that calling off the launch today was the right move, as did NASA Administrator Bill Nelson, who also participated in the briefing. The Saturday leak occurred near the base of the SLS rocket in what NASA calls a "quick disconnect," a fitting that connects a liquid hydrogen fuel line to the core booster to fuel it for launch. — A fuel leak that thwarted NASA's second attempt to launch its new Artemis 1 moon rocket on Saturday (Sept. One thing is clear, however: The quick disconnect's soft seal gasket will likely have to be replaced. The leak led to levels of flammable hydrogen gas near the rocket that were several times higher than the acceptable range, he added. 3) will likely take weeks to fix, and may even force the megarocket off its launch pad, space agency officials said. Despite three separate tries to fix the leak, engineers weren't able to stem it and ultimately stood down to assess the situation further.
