Artemis III Orion Crew Module Mate to Service Module Mate

Engineers finish connecting the Artemis III Orion crew and service modules on Friday, July 31, 2026, inside the Neil A. Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida. Now integrated, the team will power up the combined crew and service module for the first time then begin altitude chamber testing, which will put the spacecraft through conditions as close as possible to the environment it will experience in low Earth orbit. Artemis III and the four-person crew will carry out a series of objectives in low Earth orbit designed to demonstrate critical systems needed for future lunar landings, beginning with Artemis IV.
