Check out this view of the new work platforms in High Bay 3 of the Vehicle Assembly Building (VAB) taken on Feb. 22, 2019, at NASA’s Kennedy Space Center in Florida. The Exploration Ground Systems team is preparing to perform an initial swing test of the Core Stage Inter-tank Umbilical (CSITU) on the 355 foot-tall mobile launcher. The CSITU is a swing-arm umbilical that will connect to the Space Launch System (SLS) core stage inter-tank. The CSITU is located around the 140-foot level of the 355-foot mobile launcher tower. It will provide conditioned air, pressurized gases and power and data connection to the core stage.
