A view of the inside of the Pegasus barge at the Launch Complex 39 turn basin at NASA’s Kennedy Space Center in Florida, as the 212-foot-long Space Launch System (SLS) rocket core stage pathfinder is moved inside the barge on Oct. 28, 2019. The core stage pathfinder is a full-scale mock-up of the rocket's core stage. It was used by the Exploration Ground Systems Program and their contractor, Jacobs, to practice offloading, moving and stacking maneuvers inside the Vehicle Assembly Building, using important ground support equipment to train employees and certify all the equipment works properly. The pathfinder was at Kennedy for about a month. It will make the trek back to NASA's Michoud Assembly Facility in Louisiana.
