In the transfer aisle of NASA Kennedy Space Center's Vehicle Assembly Building, the Ares I-X forward segment is lifted. It will be moved into High Bay 3 for stacking with the forward center, aft center and the aft skirt segments. 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
