Kevin Unger, Quality Insurance Inspector with NASA’s Exploration Ground Systems Program, inspects the left center center solid rocket booster segment for the agency’s Artemis III SLS (Space Launch System) rocket inside the Rotation, Processing and Surge Facility at the agency’s Kennedy Space Center in Florida on Thursday, July 23, 2026. The SLS rocket’s twin boosters, 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.
