CAPE CANAVERAL, Fla. – At Launch Pad 39B at NASA's Kennedy Space Center in Florida, the rotating service structure, or RSS, has been retracted from the 327-foot-tall Ares I-X rocket, sitting atop a mobile launcher platform. The RSS was opened at midday. A full test of the rocket will be conducted, including a "hot fire" of the auxiliary power units as part of the integrated systems test. 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, along with 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 targeted for Oct. 27.
