In High Bay 3 inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, teams with Exploration Ground Systems and Jacobs use the Orion stage adapter structural test article and the Mass Simulator for Orion for testing on Aug. 13, 2021. They are stacked atop the Space Launch System (SLS) rocket. These test articles represent the mass and weight of the actual Orion stage adapter and Orion spacecraft that will be used for various tests. Launching in 2021, Artemis I will be an uncrewed test of the Orion spacecraft and SLS rocket as an integrated system ahead of crewed flights to the Moon. Under Artemis, NASA aims to land the first woman and first person of color on the Moon and establish sustainable lunar exploration.
