Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, the Space Launch System (SLS) Core Stage pathfinder is suspended by two cranes in the horizontal position above the transfer aisle on Oct. 15, 2019. The pathfinder will be lifted into the vertical position and lifted up and into High Bay 3. The 212-foot-long core stage pathfinder arrived on NASA's Pegasus Barge at Kennedy’s Launch Complex 39 turn basin wharf on Sept. 27, 2019. The Pegasus Barge made its first delivery to Kennedy in support of the agency's Artemis missions. The pathfinder is being used by Exploration Ground Systems and its 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 through at least the month of October before trekking back to NASA's Michoud Assembly Facility in Louisiana.
