CAPE CANAVERAL, Fla. – In front of the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, a technician uses a forklift to move a fuel tank after it was removed from crawler-transporter 1 CT-1 in high bay 3. The fuel tank will be transporter to the Wiltech facility at Kennedy for cleaning and inspection. Work continues in high bay 3 to upgrade CT-1 as part of its general maintenance. CT-1 could be available to carry commercial launch vehicles 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 Grossman

CAPE CANAVERAL, Fla. – Inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida, the B and D truck sections of crawler-transporter 2, or CT-2, are being raised up to prepare for installation of new roller bearing 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.
