CAPE CANAVERAL, Fla. – An aerial view shows construction progress at Launch Pad 39B at NASA’s Kennedy Space Center in Florida. A new elevator has been constructed on the surface of the pad and the crawlerway leading up to the surface is being repaired. Repairs also are being made to the crawler track panels and catacomb roof below on either side of the flame trench. Also in view are two of the three tall lightning towers that surround the pad. Upgrades are underway at Pad B and other facilities in the Launch Complex 39 area. The Ground Systems Development and Operations, or GSDO, Program office at Kennedy is leading the center’s transformation from a historically government-only launch complex to a spaceport that can safely handle a variety of rockets and spacecraft, including NASA’s Space Launch System.

The Ground Systems Development and Operations, or GSDO, Program office at Kennedy is leading the center’s transformation from a historically government-only launch complex to a spaceport that can safely handle a variety of rockets and spacecraft, including NASA’s Space Launch System.

CAPE CANAVERAL, Fla. – An aerial view, from the east looking toward the west, shows the entire Launch Pad 39B area at NASA’s Kennedy Space Center in Florida. A new elevator has been constructed on the surface of the pad and the crawlerway leading up to the surface is being repaired. Repairs also are being made to the crawler track panels and catacomb roof below on either side of the flame trench. Also in view are the water tower and the three tall lightning towers that surround the pad. To the left, in the background is the Vehicle Assembly Building. In the foreground is the shoreline of the Atlantic Ocean. Upgrades are underway at Pad B and other facilities in the Launch Complex 39 area.
