CAPE CANAVERAL, Fla. – At NASA’s Kennedy Space Center in Florida, the crawler-transporter 2, or CT-2, is on its way from the Vehicle Assembly Building to the Park Site west of the building. The transporter has new brakes and mufflers and a recently-painted white roof deck. The Ground Systems Development and Operations Program office at Kennedy is overseeing the upgrades to CT-2 so that it can carry NASA’s Space Launch System heavy-lift rocket, which is under design, and new Orion spacecraft to the launch pad. The crawler-transporters were used to carry the mobile launcher platform and space shuttle to Launch Complex 39 for space shuttle launches for 30 years. Photo credit: NASA/Jim Grossmann

CAPE CANAVERAL, Fla. – Workers from Canaveral Construction in Mims, Fla., remove the Alabama river rock from the crawlerway near the turn off to Launch Pad 39B at NASA’s Kennedy Space Center in Florida. In the background is the Launch Viewing Gantry that is a Kennedy Space Center Visitor Complex tour stop. The crawlerway is being upgraded to improve the foundation and prepare it to support the weight of NASA’s Space Launch System, or SLS, and mobile launcher on the crawler-transporter during rollout. Workers are removing the original Alabama river rock and restoring the layer of lime rock below to its original depth. Then new river rock will be added on top. The Ground Systems Development and Operations, or GSDO, Program office at Kennedy is leading the center’s transformation to safely handle a variety of rockets and spacecraft.

CAPE CANAVERAL, Fla. – At NASA’s Kennedy Space Center in Florida, screening equipment is operating to separate pulverized Alabama river rock from stones still usable in the crawlerway leading from the Vehicle Assembly Building VAB to the launch pads. The rock no longer suitable for the crawlerway will be reused in other areas of the spaceport. After years of wear from the weight of space shuttles being transported to the launch pads, the crawlerway was in need of resurfacing in preparation for future programs. The Ground Systems Development and Operations GSDO Program office at Kennedy is working to upgrade the two 40-foot-wide pathways the crawler-transporter will travel as it transports vehicles such as NASA's Space Launch System SLS rocket from the VAB to the launch pad.
