OSA STA and Umbilicals

Seen here is a close-up view of the Orion stage adapter (OSA) structural test article atop the Space Launch System (SLS) rocket inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida on Aug. 12, 2021. The test article, representing the mass and weight of the actual flight hardware, is being used for various tests inside the VAB ahead of OSA stacking operations. The first in an increasingly complex set of missions, Artemis I will test SLS and the Orion spacecraft as an integrated system prior to crewed flights to the Moon. Through Artemis, NASA will send the first woman and the first person of color to the lunar surface, as well as establish a sustainable presence on and around the Moon.
