Following the successful propellant grain inspection of two segments of the solid rocket boosters for NASA’s Space Launch System inside the Rotation, Processing and Surge Facility at NASA’s Kennedy Space Center in Florida, crews on Thursday, Dec. 21, 2023, rotate and lift the segments from horizontal into a vertical position in preparation for the agency’s Artemis II launch campaign. The Artemis II mission will send four astronauts around the Moon as part of the agency’s effort to establish a long-term science and exploration presence at the Moon, and eventually Mars.
