During the lead-up to NASA’s Artemis 1 mission back in 2022, recurring hydrogen leaks led to significant delays and a cancelled launch attempt. The agency had three years to address the underlying issues with the Space Launch System (SLS) rocket’s hardware, and yet, the Artemis 2 wet dress rehearsal felt all too familiar.

The quartet's arrival will take the ISS back up to its normal complement of seven crewmembers. The station has been staffed by just three astronauts — one American and two Russians — since Jan. 15, when SpaceX's Crew-11 mission departed for Earth.

NASA plans to test the planned leak repair with a second dress rehearsal fueling test later this month.

On Monday, after rolling the SLS rocket to be used for the Artemis II mission to the pad in January, NASA attempted its first wet-dress test with this new vehicle. At one of the main interfaces where liquid hydrogen enters the vehicle, a leak developed, not dissimilar to problems that occurred with the Artemis I rocket three years ago.
