Artemis III VAB Integration Advancing; Orion Heat Shield Inspection Passes Day 33 Post-Splashdown Milestone

At Kennedy Space Center on May 3, 2026 — day 33 post-Artemis II splashdown — parallel forward operations continued on two major fronts. In the Vehicle Assembly Building, engineers advanced integration preparations for the Artemis III SLS core stage (arrived KSC April 28), with crane rigging, safety inspections, and interface verifications underway ahead of the core stage's vertical lift into High Bay 2 for mating with the pre-positioned engine section. The Artemis III stack integration schedule — targeting a 2027 rollout to LC-39B for the Earth-orbit rendezvous and docking test with Starship HLS — depends on completing core stage vertical assembly and solid rocket booster stacking before year-end. At the Multi-Payload Processing Facility, Artemis II Orion de-servicing operations advanced through day 33: technicians continued systematic photographic documentation and dimensional measurements of each heat shield Avcoat block, completed extraction of remaining avionics units slated for refurbishment on future Orion vehicles, and finalized service module propellant offloading. The formal X-ray and computed tomography scans of heat shield blocks — scheduled at NASA's Marshall Space Flight Center in Huntsville, Alabama — will follow the MPPF visual inspection phase and are expected during summer 2026; results will define the Artemis IV crewed lunar landing timeline. The Artemis II crew (Commander Reid Wiseman, Pilot Victor Glover, Mission Specialists Christina Koch and Jeremy Hansen) continued week-five physiological reconditioning at Johnson Space Center in Houston, with NASA Human Research Program metrics showing cardiovascular function, bone density, and muscle mass indicators largely normalized — ahead of schedule for the cohort's return to full flight status.
