Inside the Rotation, Processing and Surge Facility at NASA’s Kennedy Space Center in Florida, technicians inspect the Space Launch System’s (SLS) right-hand aft skirt prior to mating it with the rocket’s right-hand motor segment – one of five segments that make up one of two solid rocket boosters – on June 24, 2020. Once the two aft skirts are mated to the aft segments, they will be moved to the Vehicle Assembly Building for stacking on the mobile launcher. Manufactured by Northrop Grumman in Utah, the twin boosters provide more than 75 percent of the total SLS thrust at launch. Under the Artemis program, NASA will land the first woman and the next man on the Moon by 2024. The first in a series of increasingly complex missions, Artemis I will test the Orion spacecraft and SLS as an integrated system ahead of crewed flights to the Moon.
