Workers prepare to unload the second half of the A-level work platforms, A north, for NASA's Space Launch System (SLS) rocket, from a heavy load transport truck in a staging area near the Vehicle Assembly Building (VAB) at NASA's Kennedy Space Center in Florida. This is the final platform delivered to Kennedy. The A-level platforms are the topmost platforms for High Bay 3 in the VAB. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to High Bay 3 to support processing of the SLS and Orion spacecraft. A total of 10 levels of new platforms, 20 platform halves altogether, will surround the SLS rocket and Orion spacecraft and provide access for testing and processing.
