Technicians with Exploration Ground Systems perform inspections of the Northrop Grumman-manufactured two aft exit cones on Wednesday, Dec. 13, 2023, inside the Rotation, Processing and Surge Facility (RPSF) at NASA’s Kennedy Space Center in Florida before mating processes begin for the agency’s Artemis II mission. The aft exit cones are attached to the bottom piece of the two boosters, (seen here in these photos), which is called the aft segment, and 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 of the agency’s first crewed mission under Artemis that will test all of the Orion spacecraft systems.

Workers with NASA’s Exploration Ground Systems (EGS) paint the bright red NASA “worm” logo on the side of an Artemis II solid rocket booster segment inside the Rotation, Processing and Surge Facility (RPSF) at Kennedy Space Center in Florida on Tuesday, Jan. 30, 2024. The EGS team used a laser projector to mask off the logo with tape, then painted the first coat of the iconic design. The booster segments will help propel the Space Launch System (SLS) rocket on the Artemis II mission to 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.

The Northrop Grumman-provided ascent test booster for the Orion Ascent Abort-2 (AA-2) Flight Test is secured on a work stand inside the Rotation, Processing and Surge Facility (RPSF) at NASA’s Kennedy Space Center in Florida on Jan. 29, 2019. The booster will be outfitted for flight. AA-2 is a full-stress test of the Launch Abort System, scheduled for April 2019. AA-2 will launch from Space Launch Complex 46, carrying a fully functional LAS and a 22,000-pound Orion test vehicle to an altitude of 31,000 feet and traveling at more than 1,000 miles an hour. The test will verify the LAS can steer the crew module and astronauts aboard to safety in the event of an issue with the Space Launch System (SLS) rocket when the spacecraft is under the highest aerodynamic loads it will experience during a rapid climb into space. NASA's Orion and Exploration Ground Systems programs and contractors from Jacob's and Northrup Grumman in conjunction with the Air Force Space and Missile Center's Launch Operations branch are performing flight operations for AA-2.

The spent segment will be placed on a railroad car and covered for the long trip back to Utah. After a mission, the spent boosters are recovered, cleaned, disassembled, refurbished and reused after each launch. After hydrolasing the interior of each segment, they are placed on flatbed trucks. The individual booster segments are transferred to a railhead located at the railroad yard at NASA's Kennedy Space Center. The long train of segments is part of the twin solid rocket boosters used to launch space shuttle Discovery in October. The NASA Railroad locomotive backs up the rail cars and the segment is lowered onto the car. The covered segments are moved to Titusville for interchange with Florida East Coast Railway to begin the trip back to Utah. Photo credit: NASA/Amanda Diller
