Artemis II LVSA Stacking

A massive crane lifts the launch vehicle stage adapter 250 feet into the air on Thursday, April 3, 2025, to prepare integration onto the SLS (Space Launch System) core stage in High Bay 3 inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. During launch and ascent, the launch vehicle stage adapter provides structural support and protects avionics and electrical devices within the upper stage from extreme vibrations and acoustic conditions. The Artemis II test flight will take a crew of four astronauts on a 10-day journey around the Moon, helping confirm the foundational systems and hardware needed for human deep space exploration.
