CAPE CANAVERAL, Fla. – At Launch Pad 39B at NASA's Kennedy Space Center in Florida, the crawler-transporter rolling toward the mobile launcher, or ML, will provide the ML a lift back to the park site near the Vehicle Assembly Building. Data on the ML collected from structural and functional engineering tests during its two-week stay on the pad will be used in the next phases of construction. The 355-foot-tall ML structure, which took about two years to construct, will be modified by NASA’s 21st Century Ground Systems Program to support NASA’s Space Launch System, the heavy-lift rocket that will launch astronauts into deep space on future exploration missions.
