The Ares I-X forward segment leaves the Rotation, Surge and Processing Facility at NASA's Kennedy Space Center in Florida. It is being transported to the Vehicle Assembly Building, which is in the background, for mating with the aft center and aft segments already stacked. Part of the Constellation Program, the Ares I-X is the test vehicle for the Ares I, which is the essential core of a space transportation system that eventually will carry crewed missions back to the moon, on to Mars and out into the solar system . The Ares I-X flight test is targeted for no earlier than Aug. 30. Photo credit: NASA/Troy Cryder
