The rotating service structure has been rolled back from the Constellation Program's Ares I-X rocket during preparations for launch.

At Launch Pad 39B at NASA's Kennedy Space Center in Florida, the rotating service structure has been rolled back from the Constellation Program's 327-foot-tall Ares I-X rocket, sitting atop its mobile launcher platform, during preparations for launch.

The transfer of the pad from the Space Shuttle Program to the Constellation Program took place May 31. Modifications made to the pad include the removal of shuttle unique subsystems, such as the orbiter access arm and a section of the gaseous oxygen vent arm, and the installation of three 600-foot lightning towers, access platforms, environmental control systems and a vehicle stabilization system. The data returned from more than 700 sensors throughout the rocket will be used to refine the design of future launch vehicles and bring NASA one step closer to reaching its exploration goals. The Ares I-X flight test is targeted for Oct. 27. For information on the Ares I-X vehicle and flight test, visit http://www.nasa.gov/aresIX. Photo credit: NASA/Kim Shiflett
