NASA, together with ATK, will conduct a full-scale test of a five-segment, solid rocket motor at the ATK Aerospace Systems test facility in Promontory, Utah, at 4:05 PM EDT, Thursday, September 8. The test will continue to advance understanding of five-segment solid rocket motor performance and assess performance at the highest end of the motor’s accepted temperature range.
The static firing of the five-segment solid rocket motor, designated Development Motor-3, will last approximately two minutes. DM-3 is the third in a series of development motors and the most heavily instrumented solid rocket motor in NASA history, with a total of 37 test objectives measured through more than 970 instruments. It incorporates several performance-based improvements to the designs of the first two development motors, and its core will be heated to 90 degrees Fahrenheit for this full-duration firing to verify the motor’s performance at high temperatures.
Journalists interested in attending the test must register with ATK. For information and to request credentials, contact ATK’s Trina Patterson at 801-699-0943 or email@example.com. The registration deadline for international reporters is August 26; the deadline for U.S. reporters is September 2.
