NASA will again attempt to launch the Artemis1 rocket on Saturday, September 3, after its first attempt was scrubbed on Monday. The historic launch was postponed after an engine bleed could not be resolved.
The launch of the most powerful rocket the world has ever seen for a mission to the moon is set to reconvene on Saturday at 2:17 p.m. eastern time, with a two hour window, NASA told reporters Tuesday.
According to the agency, a liquid hydrogen fuel line did not properly chill one of the Space Launch System’s (SLS) four core-stage engines, which are part of the preparations needed before the engine can ignite. However, NASA said there is no need to swap the engine.
Officials clarified Tuesday that there is nothing physically different about the engine that would have prevented proper cooling, but rather they suspect a sensor malfunctioned.
NASA scrubbed the Artemis I mission at 8:35am ET due to a leaking engine that was not hitting the proper temperature. This was set to be tested in the last dress rehearsal in June but a separate fuel leak cut the event short

The leaking engine, along with a crack in the core stage, were identified around 7:30am ET. NASA immediately stopped the clock at T-minus 40 minutes
