English: Crawler-transporter 2, or CT-2, nears the entrance to the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. The Ground Systems Development and Operations Program completed a roller bearing assembly test on CT-2 truck sections A and C. The left- and right-hand steering was tested in both directions. The temperature of the roller assemblies was monitored and recorded as it traveled along the crawlerway. Engineers and technicians performed visual inspections of the roller bearing pumps, valves and lines to ensure that the grease injectors worked properly and provided the required flow of grease to the new roller assemblies. 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.
