A crane lifts the second half of the B-level work platforms, B north, for NASA's Space Launch System (SLS) rocket, high up in the transfer aisle of the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida. The B north platform will lowered into High Bay 3 for installation on the north side of the high bay. The B platforms are the ninth of 10 levels of work platforms that will surround and provide access to the SLS rocket and Orion spacecraft for Exploration Mission 1. The Ground Systems Development and Operations Program is overseeing upgrades and modifications to VAB High Bay 3, including installation of the new work platforms, to prepare for NASA’s Journey to Mars.
