The Ares I-X assembly moves alongside the NASA Railroad tracks as it heads for the Vehicle Assembly Building.

At NASA's Kennedy Space Center in Florida, the Ares I-X forward assembly (comprising the frustum, forward skirt extension and forward skirt) moves alongside the NASA Railroad tracks as it heads for the Vehicle Assembly Building, in the background. In the VAB's High Bay 4, the forward assembly will undergo processing and stacking to the upper stage. Ares I-X is the flight test for the Ares I which will provide NASA an early opportunity to test and prove hardware, facilities and ground operations associated with Ares I, which is part of the Constellation Program to return men to the moon and beyond. Launch of the Ares I-X flight test is targeted for August 2009. Photo credit: NASA/Jack Pfaller
