Technicians with Exploration Ground Systems perform pre-mate inspections of the Northrop Grumman-manufactured right aft exit cone of the Artemis II Space Launch Systems solid rocket boosters on Wednesday, Dec. 13, 2023, inside the Rotation, Processing and Surge Facility (RPSF) at NASA’s Kennedy Space Center in Florida. Each of the two aft exit cones will be prepared for the agency’s Artemis II flight and attach to the aft segments of the Space Launch Systems solid rocket boosters. The exit cones act like a battery pack to provide added thrust for the boosters while protecting the aft skirts from thermal environment during launch.
