The Ares I-X aft booster segment with the aft skirt is lifted from its stand.

In the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida, 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 3. 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. 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.
