#ThrowbackThursday exactly one year -- at dawn on Feb. 5, 2014, the sunrise partially illuminates the Mobile Launcher, or ML, at NASA’s Kennedy Space Center. The ML is being modified to support the Space Launch System rocket, one of the key elements being upgraded by the Ground Systems Development and Operations Program office at Kennedy. The ML will carry the SLS rocket and Orion spacecraft to Launch Pad 39B for its first mission, Exploration Mission 1.
