The Ares I-X rocket awaits liftoff on Launch Pad 39B on its upcoming flight test.

At NASA's Kennedy Space Center in Florida, the 327-foot-tall Ares I-X rocket awaits liftoff on Launch Pad 39B on its upcoming flight test. In the background is the Atlantic Ocean. Pad modifications to support the Ares I-X 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. Part of the Constellation Program, the Ares I-X is the test vehicle for the Ares I. The Ares I-X flight test is set for Oct. 27.
