Overview
- NASA reported that liquid hydrogen loading on the Space Launch System did not work as planned during a Cape Canaveral ground test.
- Teams identified a filter system as a likely culprit and will swap the unit before resuming full procedures.
- A second Wet Dress Rehearsal later in February will repeat fueling and countdown operations without launching to verify fixes.
- An earlier rehearsal in early February revealed hydrogen leaks, leading engineers to replace seals before the latest test.
- The mission aims to fly Christina Koch, Victor Glover, Reid Wiseman and Jeremy Hansen on a roughly ten‑day lunar flyby later this year, marking the first crewed trip near the Moon since 1972.
