The Artemis III primary and back-up crew members walk by the core stage engine section for NASA’s Artemis IV mission in the transfer aisle of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida on Wednesday, Sept. 2, 2026. Dressed in blue flight suits, from left, ESA (European Space Agency) astronaut Luca Parmitano, and NASA astronauts Frank Rubio, Andre Douglas, and Bob Hines, along with Randy Bresnik (not pictured) viewed the work progress on the Artemis III SLS (Space Launch System) rocket core stage inside High Bay 2 and the solid rocket booster integration inside High Bay 3. This marked the first visit to Kennedy by the entire crew and backup crew members. Artemis III will launch four crew members aboard the Orion spacecraft to carry out a series of objectives in low Earth orbit designed to demonstrate critical systems needed for future lunar landings, beginning with Artemis IV.
