Engineers with NASA’s Exploration Ground Systems completed integrating the aerodynamic nose cones onto the left and right forward assemblies on the twin SLS (Space Launch System) solid rocket boosters, finishing their stacking operations for Artemis III inside the Vehicle Assembly Building’s High Bay 3 at NASA’s Kennedy Space Center in Florida - on Wednesday, September 30, 2026.

Each forward assembly contains an aerodynamic top, a forward skirt housing avionics, and frustum housing motors that allow the boosters to separate from the SLS core stage after launch.

The twin solid boosters will help support the remaining rocket components and the Orion spacecraft during final assembly of the Artemis III rocket and provide more than 75 percent of the total SLS thrust during liftoff from NASA Kennedy’s Launch Complex 39B.
