Ares I First Stage Motor Test Scrubbed

The stationary firing of the Ares five-segment solid motor, known as Development Motor 1, or DM-1, was scrubbed on Thursday, August 27 with twenty seconds left in the countdown. The investigation is still ongoing and ATK is targeting no earlier than Tuesday, September 1 for the motor test.

By choosing to scrub today we have not compromised any of the motor components and preserved the ability to execute a successful test and capture the data we need. Tuesday gives the test team enough time to determine the root cause and prepare the motor for testing.
