Artemis III Booster Stacking Coverage

The left-hand and right-hand aft assembly solid rocket booster segments for NASA’s Artemis III SLS (Space Launch System) rocket are secured to the mobile launcher at the agency’s Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Saturday, July 11, 2026. The 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 astronauts 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.
