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 no earlier than Aug. 30, 2009 from Launch Pad 39B.
Ares I-X is the first new launch vehicle to be stacked in in NASA’s Vehicle Assembly Building in over 30 years. When stacking in finished the Ares I-X test rocket will tower over the launch pad at height of 327 feet.

(Above) The Ares I-X aft assembly nears the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. It is being moved to the VAB for stacking to complete the Ares I-X test vehicle. The aft assembly will be the first segment to be stacked on the mobile launch platform in the VAB.

(Above) In the Vehicle Assembly Building at KSC, the Ares I-X aft booster segment with the aft skirt is lifted from its stand. The stack will be hoisted into the upper regions of the VAB and lowered onto the mobile launch platform in High Bay 1. This is the start of the buildup of the Ares I-X launch vehicle for the flight test targeted for no earlier than Aug. 30.
