Technicians stand by as the Ares I-X motor segment is moved toward a work stand in the Rotation, Processing and Surge Facility at NASA's Kennedy Space Center in Florida. Four segments were delivered to Kennedy for final processing and integration. The booster used for the Ares I-X launch is being modified by adding new forward structures and a fifth segment simulator. The motor is the final hardware needed for the rocket's upcoming test flight this summer. The stacking operations are scheduled to begin in the Vehicle Assembly Building in April.
