NASA and ATK Successfully Test Ares First Stage Motor
09.10.09
 
On Sept. 10, 2009, NASA and industry engineers lit up the Utah sky with the initial full-scale, full-duration test firing of the first stage motor for the Ares I rocket. The Ares I is a crew launch vehicle in development for NASA's Constellation Program.

ATK Space Systems conducted the successful stationary firing of the five-segment solid development motor 1, or DM-1. ATK Space Systems, a division of Alliant Techsystems of Brigham City, Utah, is the prime contractor for the Ares I first stage. Engineers will use the measurements gathered from the test to evaluate thrust, roll control, acoustics and motor vibrations. This data will provide valuable information as NASA develops the Ares I and Ares V vehicles. Another ground test is planned for summer 2010.

DM1 motor test NASA and ATK engineers successfully conducted the first stationary firing of the Ares I rocket's first-stage, five-segment, development motor, or DM-1 on Sept. 10. DM-1 is managed by the Ares Projects at NASA's Marshall Space Flight Center in Huntsville, Ala.

DM1 motor test The Ares I rocket's first-stage development motor, or DM-1, completed its first successful test firing Sept. 10. The flame exits the motor at Mach 3 and the test firing lasted for 122 seconds. DM-1 is managed by the Ares Projects at NASA's Marshall Space Flight Center in Huntsville, Ala.

DM1 motor test Data collected during the test from 650 data channels will be used 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.

Ares I rocket first-stage development motor 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.
