CAPE CANAVERAL, Fla. -- Crawler-transporter 1 continues its trek up the slope on the crawlerway leading up to Launch Pad 39A at NASA’s Kennedy Space Center in Florida. New jacking, equalizing and leveling, or JEL, hydraulic cylinders were installed on CT-1 and are undergoing a leveling and turning test as the crawler travels along the slope to the top of the pad. The Ground Systems Development and Operations Program at Kennedy continues to upgrade the crawler-transporter as part of its general maintenance. CT-1 could be available to carry a variety of launch vehicles to the launch pad. Two 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 Grossmann
