Steel structures surround High Bay 3 inside the Vehicle Assembly Building, or VAB, at NASA’s Kennedy Space Center in Florida. In view, high above, is the 175-ton crane. Banners note the heights of the Saturn V, Space Launch System, or SLS, and shuttle on the steel structure. Modifications are underway in the VAB to prepare High Bay 3 for a new platform system.

The modifications are part of a centerwide refurbishment initiative under the Ground Systems Development and Operations Program. High bay 3 is being refurbished to accommodate NASA’s Space Launch System and a variety of other spacecraft. For more information, visit http://www.nasa.gov/exploration/systems/ground/index.html.
