High up in High Bay 3 inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida, the first half of the B-level work platforms, B south, for NASA’s Space Launch System (SLS) rocket, has been lowered into place. In view below are several levels of previously installed platforms. 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.
