The Artemis I Orion spacecraft, secured on the Space Launch System (SLS) and enclosed in its launch abort system, is in view high up in High Bay 3 of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Jan. 10, 2022. Work platforms are extended around Orion and scaffolding has been secured to allow access for inspection and processing work. Artemis I will be the first integrated test of NASA’s deep space exploration systems: the Orion spacecraft, Space Launch System (SLS) rocket and the ground systems at Kennedy. 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.

Technicians with NASA’s Exploration Ground Systems lower a mock-up, or pathfinder, of the Space Launch System’s (SLS) center booster segment onto an aft pathfinder segment inside the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida on Sept. 14, 2020. Teams rehearsed stacking both pathfinder segments on top of the mobile launcher in High Bay 3 of the VAB in preparation for the Artemis I launch. Stacking of the actual SLS booster segments will occur later this year, when the rocket’s core stage arrives at Kennedy. Artemis I is the first in a series of increasingly complex missions that will test SLS and the Orion spacecraft as an integrated system prior to crewed flights to the Moon.
