"This shipment means great things for the Ares I-X mission," said Ares I-X Deputy Mission Manager, Steve Davis. "It's wonderful to see the next generation of American spaceflight continue to take shape. The excitement is really building now as we start stacking the pieces and preparing for launch later this year."
The Ares I-X will be the first flight test for the Ares I rocket; the agency's next-generation spacecraft and crew launch vehicle system. The flight will provide NASA an early opportunity to test and prove hardware, analysis models, facilities and ground operations associated with Ares I.
The Ares I-X rocket is a combination of existing and simulator hardware that will resemble the Ares I rocket in size, shape and weight. It will provide valuable data to guide the final design of the Ares I. The test flight also will bring NASA one step closer to its goals of returning to the moon, and traveling to destinations beyond. The Ares I-X launch is scheduled later in 2009.
The Ares I-X first stage uses a four-segment solid rocket motor, capable of generating 3.3 million pounds of thrust. The motor provides the primary propulsion for the vehicle from liftoff to stage separation 120 seconds into the flight. The motor segments were taken from the existing space shuttle solid rocket booster inventory for the flight test. The booster used for the Ares I-X flight test is being modified to meet Ares needs by adding new forward structures and a fifth segment simulator to better replicate the size and shape of the Ares I crew launch vehicle. NASA's Marshall Space Flight Center in Huntsville, Alabama, manages the first stage project for the Ares I-X mission, located at NASA's Johnson Space Center in Houston.

The first stage segments are just about ready to go. They have a long trip ahead of them from first stage contractor ATK’s facilities in Promontory, Utah to the launch site at Kennedy Space Center in Florida.
Last week, using specialty transporters, ATK moved the Center Aft Segment to a holding facility where it will be housed in preparation for the cross-country trek via railcar. Someone described these transporters as looking like something out of the Transformers movie and I don’t think that’s too far off. They are impressive looking vehicles.
That big black line you see running diagonally down the side is called a Z-stripe. The Z-stripe is a 24-inch wide stripe painted on the first stage motor segments that wraps from the top of the motor to the bottom. The main purpose of the Z-stripe is to provide a way for the I-X team to determine the roll attitude and rate from footage recorded by cameras on the ground. That footage serves as a backup to on-board data gathered during the flight. The Z-stripe will also provide confirmation that the rocket rolled 90° shortly after lift-off from the pad like it is supposed to. Measurement from watching the Z-stripe could be very helpful in the case that the flight goes differently than expected.
