Artemis III Booster Stacking - Right Forward Booster Segment Mated (Photo Release - September 24)

In High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, the final left and right forward solid rocket booster motor segments for Artemis III are integrated onto the Mobile Launcher for the SLS (Space Launch System) rocket on Thursday, September 24, 2026.

The twin boosters, consisting 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.
