In High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, the left and right aft center booster segments for Artemis III are lowered onto their aft assembly segments for integration on the Mobile Launcher for the SLS (Space Launch System) rocket on Wednesday, August 12, 2026.

The twin boosters, comprising of 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.
