NASA AND ATK SCHEDULE MOTOR TEST FOR ARES ROCKET ON SEPT. 10

WASHINGTON -- NASA and Alliant Techsystems Inc., or ATK, have
rescheduled the test of the new first-stage solid rocket motor for
the Ares I rocket. The static firing of the five-segment solid motor,
designated development motor -1, is scheduled for 1 p.m. MDT on
Thursday, Sept. 10, at the ATK test facility in Promontory, Utah. The
first firing attempt on Aug. 27 was scrubbed because of an anomaly
with the ground test controller.

The goal of this test is to obtain valuable thrust, roll-control,
acoustics and vibration data as engineers continue to design the Ares
vehicles.

To attend the test, journalists must register with ATK's Trina
Patterson at 801-699-0943 by Sept. 8. News media bringing live
broadcast trucks must request parking prior to the event.

The test will be carried live on the NASA media channel beginning 10
minutes prior to the firing. For NASA TV streaming video, downlink

In addition, the NASA Ares Twitter feed will be updated throughout
the
day. To follow, visit:

After the test, representatives from NASA and ATK will hold a media
teleconference at 1:45 p.m. To participate, reporters should e-mail
Ashley Edwards at for dial-in information.
