Platforms surround the 327-foot tall Ares I-X rocket in NASA Kennedy Space Center's Vehicle Assembly Building. The rocket is stacked on the mobile launcher platform in High Bay 3. Five super stacks make up the upper stage that are integrated with the four-segment solid rocket booster first stage below. Ares I-X is the test vehicle for the Ares I, which is part of the Constellation Program to return men to the moon and beyond. The Ares I-X flight test is targeted for Oct. 31.
