On July 20, 2009, NASA and ATK unveiled the completed Ares I first stage five-segment solid rocket booster in Promontory, Utah. The completed solid rocket booster is now installed horizontally in a test stand that was modified from the space shuttle's four-segment configuration to fit the new five-segment Ares I booster. Instrumentation will be installed over the next month in preparation for the first major ground test of the NASA Constellation program August 27.
NASA's Ares I first-stage motor sits on ATK Space System's test stand in Promontory, Utah, awaiting its test firing, set for Aug. 27. The 154-foot solid rocket motor will produce heat two-thirds the temperature of the sun and its 12-foot-diameter cylinder will deliver 3.6 million pounds of thrust. The Ares I first-stage development motor, or DM-1, is managed by the Ares Projects at NASA's Marshall Space Flight Center in Huntsville, Ala. ATK Space Systems, a division of Alliant Techsystems of Brigham City, Utah, is the prime contractor for the Ares I first stage.

The stationary firing of the five-segment solid rocket motor will be conducted by ATK Space Systems, a division of Alliant Techsystems of Brigham City, Utah, the prime contractor for the Ares I first stage. The motor will provide the backbone for the Ares I, generating up to 3.6 million pounds of thrust, or lifting power, at launch. DM-1 is managed by the Ares Projects at NASA's Marshall Space Flight Center in Huntsville, Ala.
All systems are go for the first test of the Ares I rocket's first-stage development motor, or DM-1, set for Aug. 27. The five-segment solid rocket motor is capable of producing 22 million horsepower, equivalent to the energy produced by 25,882 race cars. Data will be collected during the test from 650 sensors to evaluate the motor's performance. This test and those that follow will provide engineers with valuable information as they develop the safest and most reliable motor possible for NASA's next generation rocket. DM-1 is managed by the Ares Projects at NASA's Marshall Space Flight Center in Huntsville, Ala. The stationary test firing will be conducted by ATK Space Systems, a division of Alliant Techsystems of Brigham City, Utah, the prime contractor for the Ares I first stage.

On July 20, NASA and ATK employees, guests and media gathered to watch the movable building, which houses the solid rocket motor, roll back and reveal the assembled test article.
The Ares I first stage development motor includes a movable nozzle with a larger throat diameter and exit cone designed to improve overall performance.
