NASA reached a key milestone in the Vehicle Assembly Building (VAB) at the agency's Kennedy Space Center in Florida. A year of platform installations came to conclusion in January as the final work platform, A north, was lifted, installed and secured recently on its rail beam on the north wall of High Bay 3 inside the iconic facility. The installation of the final topmost level completes the 10 levels of work platforms, 20 platforms halves altogether, that will surround NASA's Space Launch System (SLS) rocket and the Orion spacecraft and allow access during processing for missions, including the first uncrewed flight test of Orion atop the SLS rocket. The A platforms will provide access to the Orion spacecraft's Launch Abort System (LAS) for Orion lifting sling removal and installation of the closeout panels. LAS Antenna Testing also is performed on this level. The platforms were mated with two, 60,000-pound rail beam assemblies that allow the platforms to move towards and away from...
