Overview
- The repaired SLS/Orion stack reached Launch Complex 39B after a 6–6.4 km rollout on Crawler-Transporter 2 that took roughly 10–12 hours.
- NASA kept the no-earlier-than April 1 target for the roughly 10-day lunar flyby, pending pad checkouts and standard technical and weather reviews.
- Engineers addressed a February fault that blocked helium flow to the upper stage and performed battery swaps, seal replacements and umbilical re-tests in the VAB.
- Space-weather researchers flagged heightened solar activity as a potential risk, and NASA says it will watch conditions continuously without changing the schedule for now.
- The crew—Reid Wiseman, Victor Glover, Christina Koch and Canada’s Jeremy Hansen—will fly a free-return trajectory around the Moon before a Pacific splashdown.
