Overview
- NASA partially loaded liquid hydrogen during a Feb. 12 confidence test to verify newly replaced seals after an earlier leak halted a full rehearsal.
- Engineers traced the reduced hydrogen flow to ground support equipment rather than the rocket, with a clogged filter suspected as the cause.
- Teams will purge lines, inspect hardware, and replace the filter before scheduling a second full wet dress rehearsal.
- Officials said March remains the earliest launch opportunity, with five identified dates between March 6 and March 11 and April as a fallback if needed.
- The mission will send astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen on a lunar flyby, a key step toward later Artemis landings.
