NASA’s crawler-transporter 2, also called CT-2, returns to the crawler park site after a test run to Launch Pad 39B at NASA's Kennedy Space Center in Florida. Upgrades to the crawler include 88 new roller bearings, 22 on each "truck" section, and a new jacking, equalizing and leveling system. Fondly referred to as the "workhorses" of the space program, both crawlers, CT-1 and CT-2, have served the agency's space programs for 50 years. In the background is the Vehicle Assembly Building. The Ground Systems Development and Operations Program at Kennedy has made steady progress on upgrades and modifications to CT-2 to be ready to support NASA's Space Launch System and Orion spacecraft, and CT-1 to support a variety of other launch vehicles as the center transforms to a multi-user spaceport.
