Overview
- The move from the Vehicle Assembly Building to Launch Pad 39B is now planned no earlier than March 20, a one-day slip from March 19.
- Engineers replaced the electrical harness linked to the flight termination system and are completing closeout checks ahead of rollout.
- NASA says the revised timeline still supports a potential April 1 launch window opening, pending final pad readiness and weather.
- Once underway, the crawler-transporter journey to Pad 39B is expected to take up to 12 hours, with NASA planning a live stream of the rollout.
- The adjustment follows earlier prelaunch work that addressed a dislodged helium seal, refreshed batteries, and minor leak checks during wet dress rehearsals.
