Ares 1-X Update

Ares I-X Test To Study Vibrations, Aerospace Daily & Defense Report

“NASA engineers are adding instrumentation to the first full-scale flight version of the Ares I crew launch vehicle to gather real data about vibrations from its solid-fuel first stage that initially were predicted to be seriously out-of-spec. Those predictions, which could mean expensive modifications to the Ares I and the Orion crew exploration vehicle that will ride atop it, are based largely on ground-test data. Managers hope flight-test results from the Ares I-X flight will give them a much better idea of just how bad the problem is, and what it will take to solve it.”
