CAPE CANAVERAL, Fla. -- Technicians in the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, prepare to jack crawler-transporter 2, or CT-2, four feet off the floor to facilitate removal of the roller bearing assemblies. After inspections, new assemblies will be installed. 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 and new Orion spacecraft to the launch pad. For more than 45 years the crawler-transporters were used to transport the mobile launcher platform and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B.
