CAPE CANAVERAL, Fla. – In the transfer aisle of the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, a crane lifts the conjoined forward and center segments of the fifth segment simulator for the Ares I-X. The segments will be mated to the simulator’s aft segment, at left. Ares I-X is the test vehicle for the Ares I, a component of the Constellation Program to return men to the moon and beyond. Ares I is the essential core of a safe, reliable, cost-effective space transportation system that eventually will carry crewed missions back to the moon, on to Mars and out into the solar system. The launch of the Ares I-X flight test is targeted for August 2009. Photo credit: NASA/Jim Grossmann
