The test, at NASA partner Alliant Techsystems, was in Utah at 3:00 P.M. EST and was intended to last two minutes. The goal was to obtain data on thrust, roll control, acoustics, and vibrations to aid engineers in designing Ares I. But the test was scrubbed 20 seconds before ignition of the 154-foot motor, which was anchored to the ground horizontally. The problem: failure of a power unit that drives hydraulic tilt controls for the rocket's nozzle, according to a local report. The static firing test of the motor has not yet been rescheduled.
