The Artemis I aft skirts for NASA's Space Launch System (SLS) rocket’s twin solid rocket boosters are transported to the Rotation Processing and Surge Facility (RPSF) at the agency’s Kennedy Space Center in Florida on June 10, 2020. The aft skirts were refurbished by Northrop Grumman. They house the thrust vector control system, which controls 70 percent of the steering during initial ascent of the SLS rocket. The segments will remain in the RPSF until ready for stacking with the forward and aft parts of the boosters on the mobile launcher in High Bay 3 of the Vehicle Assembly Building. Through the Artemis Program, NASA is working to land the first woman and next man on the Moon by 2024.
