Teams with NASA’s Exploration Ground Systems Program lift the agency’s SLS (Space Launch System) core stage inside the transfer aisle at the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida on Wednesday, Dec. 11, 2024. The one-of-a kind lifting beam is designed to move the core stage from the transfer aisle to High Bay 2 where it will remain while teams stack the two solid rocket boosters for the SLS core stage.
