The engineering complex at NASA’s Marshall Space Flight Center in Huntsville, Alabama, was developed beginning in 2005 with construction of Building 4600, at upper right, the first “green,” LEED®-certified facility built by NASA. LEED certification is a voluntary, consensus-based national standard, created by the U.S. Green Building Council for Leadership in Energy and Environmental Design, applied to the development of high-performance, sustainable structures. The engineering complex, southwest of the intersection of Rideout and Martin roads on Redstone Arsenal, includes offices, laboratories and test facilities primarily for engineers in Marshall’s Materials and Processes Laboratory and its Spacecraft and Vehicle Systems Department. Researchers in the 4600 complex are developing next-generation launch vehicle technologies and supporting a variety of Earth, space and solar science missions. (NASA/MSFC)
