Final securing of the Space Launch System (SLS) Launch Vehicle Stage Adapter (LVSA) to the Core Stage for Artemis 1 in the Vehicle Assembly Building (VAB) at the Kennedy Space Center (KSC) in Florida was slowed down by issues discovered when workers started bolting the two elements together. NASA’s Exploration Ground Systems (EGS) and prime launch processing contractor Jacobs lifted the LVSA by crane up on top of the SLS Core on June 22 with mating expected to be finished that night; however, hard-mate was not completed for several days.
