CAPE CANAVERAL, Fla. – The mobile launcher, or ML, makes its way past the turn basin as dusk descends on NASA's Kennedy Space Center in Florida. The ML is nearing the end of its 4.2-mile trek from Launch Pad 39B 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.
