Replace, 11:28 a.m. EDT: The Artemis 1 mission has been scrubbed as a result of a gasoline leak. The following doable alternative is Monday (Sept. 5).
CAPE CANAVERAL, Fla. — NASA engineers are working to stem a gasoline leak on its huge new moon rocket forward of a vital take a look at flight on Saturday (Sept. 3).
NASA started fueling the Artemis 1 moon rocket, NASA’s first Area Launch System (SLS), early Saturday to launch an uncrewed Orion spacecraft to the moon from Pad 39B right here on the Kennedy Area Heart at 2:17 p.m. EDT (1817 GMT). However a persistent liquid hydrogen gasoline leak detected has slowed launch preparations.
NASA has a two-hour window wherein to launch the mission, with promising climate forecast various between 60% and 80% “go,” the company has mentioned. You’ll be able to watch it launch stay on-line.

The hydrogen leak was first detected at 7:15 a.m. EDT (1115 GMT) as NASA started filling the huge SLS rocket with the 730,000 gallons of liquid hydrogen and liquid oxygen propellant wanted for launch. The leak is within the connection level of an 8-inch hydrogen gasoline line close to the engine compartment on the base of the 32-story rocket.
Engineers first tried to heat the connector and chill it with chilly gasoline to stem the leak, then tried to repressurize it with helium to resolve it. Each makes an attempt failed, with NASA making an attempt that first warm-and-chill methodology once more to cease the leak.
A glitch-free fueling course of for Artemis 1 can take as much as 4 hours, However there’s not a lot room within the schedule for delays, NASA has mentioned.
It was through the fueling course of (or “tanking” as NASA calls it) that launch controllers hit a snag through the company’s first launch try on Monday (Aug. 29). NASA referred to as off that launch attempt when it couldn’t verify that one of many 4 RS-25 essential engines of the SLS core stage was at its correct chilled temperature of minus 420 levels Fahrenheit for launch.
The company in the end decided {that a} dangerous sensor induced the difficulty and carried out workarounds for Saturday’s launch try. On Saturday, NASA deliberate to start the principle engine chill down course of earlier to permit extra time for the SLS rocket’s engines to achieve their goal temperature. However that course of has been delayed by the gasoline leak.
NASA’s Artemis 1 mission is the primary take a look at flight for NASA’s Artemis program to return astronauts to the moon by 2025. The mission is a 37-day journey across the moon to confirm the Orion spacecraft and SLS rocket are secure for astronauts. The mission will even deploy 10 Artemis cubesats on the best way to the moon and carries a sequence of experiments to measure the astronaut expertise on the Orion spacecraft.
Artemis 1 is scheduled to return to Earth on Oct. 11 with a splashdown within the Pacific Ocean off the coast of California. If all goes properly, NASA goals to launch a crew across the moon on the Artemis 2 mission in 2024, adopted by the Artemis 3 crewed lunar touchdown in 2025.
