SLS Core Stage Pathfinder Transport to VAB

The 212-foot-long Space Launch System (SLS) rocket core stage pathfinder is being transported to the Vehicle Assembly Building at NASA's Kennedy Space Center on Oct. 1, 2019. The Pegasus Barge made its first delivery to Kennedy in support of the agency's Artemis missions. The upgraded 310-foot-long barge arrived Sept. 27, 2019, ferrying the SLS core stage pathfinder, a full-scale mock-up of the rocket's core stage. It will be used by the Exploration Ground Systems Program and their contractor, Jacobs, to practice offloading, moving and stacking maneuvers, using important ground support equipment to train employees and certify all the equipment works properly. The pathfinder will stay at Kennedy for approximately one month before trekking back to NASA's Michoud Assembly Facility in Louisiana.
