Artemis III SLS Core Stage Joins Boosters at Kennedy

Oct 28, 2026

NASA’s Artemis III SLS (Space Launch System) core stage is integrated alongside the twin solid rocket boosters on Oct. 28 inside the Vehicle Assembly Building’s High Bay 3 at NASA’s Kennedy Space Center in Florida.  

Technicians lifted the 212-foot rocket stage from the facility’s High Bay 2 using a one-of-a kind lifting beam designed to place the stage onto the mobile launcher. Once testing and checkouts are complete, teams will roll the core stage and booster stack out to Launch Pad 39B to conduct a tanking test where liquid hydrogen and liquid oxygen fuel will be loaded only into the core stage and launch teams will practice countdown procedures and timelines.  

The Artemis III mission will launch NASA astronauts Randy Bresnik, Frank Rubio, Andre Douglas, and ESA (European Space Agency) astronaut Luca Parmitano in the Orion spacecraft on top of the SLS rocket to test rendezvous and docking capabilities between Orion and commercial spacecraft from Blue Origin and SpaceX ahead of future mission to land astronauts on the Moon.
