Technicians use a massive crane to rotate and lift the right-hand aft center assembly solid rocket booster segment for NASA’s Artemis III SLS (Space Launch System) rocket onto a work stand at the Rotation, Processing, and Surge Facility at the agency’s Kennedy Space Center in Florida on Wednesday, July 29, 2026, with the left-hand aft center assembly already vertical on its work stand. The twin boosters, comprising five segments each manufactured by Northrop Grumman in Utah, will provide more than 75 percent of the SLS rocket’s total thrust at launch. 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.
