The shipping container has been removed from the second of two Northrop Grumman-manufactured aft exit cones to arrive for the Space Launch System’s solid rocket boosters inside the Rotation, Processing and Surge Facility at NASA’s Kennedy Space Center in Florida on Dec. 9, 2019. The right 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.
