After a scrubbed launch nearly a week ago, Saturday NASA will try once more to launch Artemis 1 from the Space Coast.

NASA began fueling its massive new rocket early Saturday (Sept. 3), setting the stage for a critical Artemis 1 test flight to the moon.

EDT, three attempts to address the issue yielded the same results. The launch window was set to open at 2:17 p.m. A liquid hydrogen leak in a connection between ground systems and the Space Launch System rocket could not be resolved after multiple tries to address the problem remotely spanning four hours at Kennedy Space Center in Florida.

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. [postponement of the first launch attempt](https://www.theguardian.com/science/2022/aug/29/artemis-scrubbed-nasa-cancels-moon-launch-engine) last Monday. [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.

EDT (2257 GMT), NASA has said. If NASA has to roll Artemis 1's SLS rocket back inside its Vehicle Assembly Building hangar for repairs, the launch will slip to October, Nelson said. EDT (2212 GMT). EDT (1518 GMT) during a live broadcast. EDT (1817 GMT) on Saturday, but a hydrogen fuel leak detected about seven hours before liftoff thwarted the attempt. 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.

"This time we're going to learn how to live in that hostile environment for long periods of time, all with the purpose that we're going to Mars." Nasa engineers "have checked it, as we say in the South of the United States, from 'gizzard to gizzard,'" Nelson said. "A bit of perspective: 11 [NASA] Shuttles had to be rolled back to fix something. "Otherwise, relying on such an expensive single-use, heavy-lift rocket system will, in our judgment, inhibit if not derail NASA's ability to sustain its long-term human exploration goals of the moon and Mars." NASA is banking heavily on a successful mission for Artemis 1, which has come under scrutiny for a price-tag that has ballooned to eye-watering levels. The flight will be followed by Artemis 2 and Artemis 3 in 2024 and 2025/2026 respectively. This will put the capsule's ablative heat shield to the test, which, alongside the craft's parachute, will use air friction to slow Orion down to just 20 mph (32.2 km/h), after which it should plop down safely in the Pacific Ocean off the coast of Baja California, Mexico, ready for retrieval. "Teams attempted to fix an issue related to a leak in the hardware transferring fuel into the rocket, but were unsuccessful." Stowed aboard Orion are three mannequins that NASA will use to test radiation and heat levels during the flight. The rocket's first attempt was scrubbed because engineers were unable to cool one of the rocket's four core stage RS-25 engines down to a safe temperature in time for liftoff. A crowd of 400,000 people turned up to watch the Artemis 1 rocket scheduled launch from the Kennedy Space Center in Florida today (Sept. Engineers tried and failed to plug the leak three times, NASA said.

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.

Following a failed attempt earlier this week, NASA has once again delayed the start of its Artemis 1 Moon mission.

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.

NASA's next-generation Space Launch System likely won't fly before the end of September.
