CAPE CANAVERAL, Fla. – Preparations are underway to begin removing the jacking, equalizing and leveling, or JEL, hydraulic cylinders from crawler-transporter 1 at the crawler transporter maintenance facility at NASA’s Kennedy Space Center in Florida. Sixteen new JEL hydraulic cylinders will be installed on CT-1 to increase load carrying capacity and reliability. The Ground Systems Development and Operations Program at Kennedy continues 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/Tim Jacobs
