Overview
- Engineers swapped an electrical harness on the core stage’s flight termination system during closeout work, with preparations now nearing completion.
- Managers plan to set the rollout start time on Wednesday, March 18, with the move possible on Thursday, March 19, or Friday, March 20.
- The SLS/Orion stack’s trip from the Vehicle Assembly Building to Launch Pad 39B is expected to take up to 12 hours and will be livestreamed by NASA.
- Launch opportunities begin as early as Wednesday, April 1, with additional windows through April 6 and April 30, contingent on weather and final pad testing.
- A helium-flow fault found during the February 21 wet dress rehearsal was traced to a dislodged seal and fixed; NASA does not plan another rehearsal and will fully tank on launch day.
