OSA Arrival in VAB High Bay 4

Under a protective cover, the Orion Stage Adapter (OSA) arrives in High Bay 4 of the Vehicle Assembly Building on Oct. 4, 2021, at NASA's Kennedy Space Center in Florida. Teams will lift the ring-shaped OSA, filled with shoebox-sized CubeSats, and connect it to the Interim Cryogenic Propulsion Stage (ICPS). The Orion spacecraft will be secured on top of the Space Launch System (SLS) rocket to complete the stack ahead of the Artemis I launch. This mission will be the first integrated flight test of the SLS and Orion spacecraft. In later missions, NASA will land the first woman and the first person of color on the surface of the Moon, paving the way for a long-term lunar presence and serving as a steppingstone on the way to Mars.
