In NASA's Vehicle Assembly Building, assembly of the giant Ares I-X rocket is complete. The 327 foot tall rocket is one of the largest processed in there, rivaling the height of the Apollo Program's Saturn V. Ares I-X is a test vehicle for the Constellation Program to return men to the moon and on to Mars. The Ares I-X flight test is targeted for Oct.31.
