The solid rocket booster aft skirt segments for NASA’s Artemis III SLS (Space Launch System) rocket arrive at a rail yard near the agency’s Kennedy Space Center in Florida on Wednesday, April 8, 2026. Comprising the bottom of the rocket’s twin, five-segment solid rocket boosters, the aft skirt segments traveled by train in specialized transporters to the Florida spaceport and will be transferred from the rail yard to NASA Kennedy’s Rotation, Processing and Surge Facility for processing. The Artemis III mission will launch crew in the Orion spacecraft on top of the SLS rocket to test rendezvous and docking capabilities between Orion and commercial spacecraft needed to land astronauts on the Moon.
