WASHINGTON — NASA has stopped work on a second mobile launch platform intended for an upgraded version of the Space Launch System the agency no longer plans to develop.
At a March 29 briefing, Shawn Quinn, manager of NASA's Exploration Ground Systems program, said the agency had issued a stop-work order for Mobile Launcher 2, or ML-2, the launch platform that NASA was building for the SLS Block 1B rocket.
With the successful launch of Artemis 2 on April 1, NASA is now beginning to review how the mobile launch platform handled the liftoff of the SLS. That platform suffered more damage than expected during the Artemis 1 launch in 2022.
