CAPE CANAVERAL, Fla. – At Launch Pad 39B at NASA’s Kennedy Space Center in Florida, construction workers inspect the brick walls of the flame trench area that is located below and between the left and right crawlerway tracks. Pad B is being refurbished to support NASA’s Space Launch System and other launch vehicles. The Ground Systems Development and Operations, or GSDO, Program at Kennedy is leading the center’s transformation to safely handle a variety of rockets and spacecraft.
