Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, a ground support technician assists as a crane lifts up a section of the treads on the C truck of crawler-transporter 2, or CT-2. The treads are being removed in order to gain access to remove the gear boxes.
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.
