NASA Eyes New Date for Artemis II Rocket Rollout - NASA

Teams are now targeting no earlier than Friday, March 20, to roll NASA's Artemis II rocket from the Vehicle Assembly Building out to Launch Pad 39B, maintaining the opportunity for a Wednesday, April 1, launch attempt.
Over the weekend at the agency's Kennedy Space Center in Florida, engineers were completing closeout activities ahead of rollout, previously slated for Thursday, March 19. Teams identified an electrical harness for the flight termination system on the core stage needed replacement. They have since addressed the issue and continue to complete preparations to roll out later this week.
The trek to the launch pad takes up to 12 hours aboard the crawler-transporter. The agency will provide a live stream of the rocket's journey to the pad.
