Artemis II LVSA in High Bay

NASA’s Artemis II hardware, the launch vehicle stage adapter, is inside High Bay 4 on Thursday, March 20, 2025, at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida ahead of rocket stacking operations. The cone shaped launch vehicle stage adapter connects the SLS (Space Launch System) Moon rocket to the upper stage, the interim cryogenic propulsion stage, and protects the rocket’s flight computers, avionics, and electrical devices during launch and ascent during the Artemis missions.
