The Orion spacecraft for NASA’s Artemis I mission, fully assembled with its launch abort system, is stacked on the Space Launch System (SLS) rocket in High Bay 3 of the Vehicle Assembly Building at Kennedy Space Center in Florida on Oct. 20, 2021. The stacking of Orion on top of the SLS completes assembly for the Artemis I flight test. Teams will begin conducting a series of verification tests ahead of rolling out to Launch Complex 39B for the Wet Dress Rehearsal. Photo: NASA/Radislav Sinyak
