The crawler-transporter modifications are part of NASA’s Ground Systems Development and Operations Program (GSDO) efforts to upgrade Kennedy’s infrastructure to support the 21st-century spaceport.

|Crawler-transporter-2 (CT-2) is on its way from the Vehicle Assembly Building to the Park Site west of the building. The crawler-transporters were an integral part of the Apollo and Space Shuttle Programs. For more than 45 years the crawlers were used to transport the mobile launcher platforms and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B. At the end of 2011, engineers began modifying CT-2 to ensure its ability to transport launch vehicles currently in development, such as NASA’s Space Launch System. Photo credit: NASA/Jim Grossmann|
