The Ares I-X fifth segment simulator aft section is being transported from the Astrotech facility in Titusville, Fla., to NASA's Kennedy Space Center in Florida. Ares I-X is the test vehicle for the Ares I, which is part 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. Ares I-X is targeted for launch in July 2009. Photo credit: NASA/Troy Cryder
