Nasa calls off Artemis 1 moon rocket launch for second time after ... (The Guardian)

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.

Second Artemis 1 launch attempt scrubbed - SpaceNews (SpaceNews)

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.

NASA Scrubs Artemis I Rocket Launch For Second Time After Leak (Forbes)

Due to lift-off at 2:17 p.m. EST on September 3, 2022 from Launch Pad 39B at NASA's Kennedy Space Center in Florida, NASA's Space Launch System (SLS) suffered ...

high, the SLS is also a “Moon rocket” with 8.8 million pounds (3.9 million kg) of thrust. Orion will enter an elliptical orbit of the Moon that will see them get to within 62 miles above its surface and about 40,000 miles beyond it. The SLS is a largest rocket constructed since the agency’s Saturn V “Moon rocket” was last used in 1973. When Artemis I does finally lift-off it will embark on a 1.3 million miles (2.1 million kilometers) journey. That would mean a much longer delay. Due to lift-off at 2:17 p.m.

Fuel leak on Artemis 1 moon rocket may take weeks to repair, NASA ... (Space.com)

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.

Artemis-1 launch called off by NASA amidst Hydrogen leak. Read ... (Economic Times)

NASA hopes to take Artemis-1 to the moon, but the rocket seems to be plagued with technical issues. It is the second calling off the rocket launch as it ...

There was a leak in the [hydrogen](/topic/hydrogen)line that was used to fill the rocket's core tank. [SLS](/topic/sls), this was the latest. The date for the next launch is not clear yet, but it could be on Monday or Tuesday. NASA engineers commented that it is common to find minor flaws during a rocket launch. [Artemis-1](/topic/artemis-1)launch has been called off twice a week due to technical faults.

Hit by leaks, Artemis-1 mission to Moon unlikely to launch anytime ... (India Today)

Days after Nasa scrubbed the second launch attempt of the Space Launch System (SLS) on a maiden voyage to the Moon, it is unlikely to happen in the current ...

That was on top of leaks detected during countdown drills earlier in the year. Meanwhile, engineers are working to fix the hydrogen leak in a quick disconnect, an interface between the liquid hydrogen fuel feed line and the Space Launch System (SLS) rocket. The next opportunity to launch will only open in late September and early October.
