CAPE CANAVERAL, Fla. – Near the Vehicle Assembly Building, or VAB, at NASA’s Kennedy Space Center in Florida, an old roller shaft bearing that was removed from crawler-transporter 2, or CT-2, is being discarded. Inside the VAB, new roller shaft bearings will be installed on CT-2. Work continues in high bay 2 to upgrade CT-2. The modifications are designed to ensure CT-2’s ability to transport launch vehicles currently in development, such as the agency’s Space Launch System, to the launch pad. The Ground Systems Development and Operations Program office at Kennedy is overseeing the upgrades. 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.
