CAPE CANAVERAL, Fla. -- A water moccasin snake travels across the gravel surface near the Mobile Launcher, or ML, at the Mobile Launcher Park Site at NASA’s Kennedy Space Center in Florida. Nearby, the haunch, a structure that will support the launch vehicle on the ML, arrives by flatbed truck at the park site. The ML is being modified and strengthened to accommodate the weight, size and thrust at launch of NASA's Space Launch System, or SLS, and Orion spacecraft. In 2013, the agency awarded a contract to J.P. Donovan Construction Inc. of Rockledge, Fla., to modify the ML, which is one of the key elements of ground support equipment that is being upgraded by the Ground Systems Development and Operations Program at Kennedy. The existing 24-foot exhaust hole is being enlarged and strengthened for the larger, heavier SLS rocket. The ML will carry the SLS rocket and Orion spacecraft to Launch Pad 39B for its first uncrewed mission, Exploration Mission-1, in 2018. Photo credit: NASA/Kim Shiflett
