ATK and NASA to Perform First Ground Test of the Ares I Five-Segment Solid Rocket Motor
Test is a Major Milestone for ATK, NASA on Ares I Program
Alliant Techsystems (NYSE: ATK) Space Systems and NASA identified the issue that resulted in the scrub of last week’s test. A component of the ground controller unit, which sends power to the system that moves the nozzle during the test, failed and has been replaced. The test has been rescheduled for Thursday, Sept. 10. Final testing of the ground system will continue over the weekend and early next week.
