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.

KENNEDY SPACE CENTER, FLA. -- Solid rocket motor segments and two aft exit cone segments arrive by rail at NASA's Kennedy Space Center. While enroute, solid rocket motor segments were involved in a derailment in Alabama. The rail cars carrying these segments remained upright and were undamaged. An inspection determined these segment cars could continue on to Florida. The segments themselves will undergo further evaluation at Kennedy before they are cleared for flight. Other segments involved in the derailment will be returned to a plant in Utah for further evaluation. Photo credit: NASA/George Shelton

KENNEDY SPACE CENTER, FLA. -- The locomotive and rail cars carrying solid rocket booster motor segments and two aft exit cone segments roll past the Vehicle Assembly Building to the Rotation, Processing and Surge Facility (RPSF) in Kennedy Space Center's Launch Complex 39 Area. The RPSF is used for solid rocket motor receiving, rotation and inspection, and supports aft booster buildup. When live solid rocket motor segments arrive at the processing facility, they are positioned under one of the cranes. Handling slings are then attached to and remove the railcar cover. The segment is inspected while it remains horizontal. The two overhead cranes hoist the segment, rotate it to a vertical position and place it on a fixed stand. The aft handling ring is then removed. The segment is hoisted again and lowered onto a transportation and storage pallet, and the forward handling ring is removed to allow inspections. It is then transported to one of the surge buildings and temporarily stored until it is needed for booster stacking in the VAB.
