The Northrop Grumman-manufactured right aft exit cone, the second of two for the Space Launch System’s solid rocket boosters, is in view inside the Rotation, Processing and Surge Facility at NASA’s Kennedy Space Center in Florida on Dec. 9, 2019. The aft exit cone was shipped from Promontory, Utah. It will be checked out and prepared for the Artemis I uncrewed test flight. The aft exit cones sit at the bottommost part of the twin boosters. The cones help provide added thrust for the boosters, while protecting the aft skirts from the thermal environment during launch.
