First Stage Design Problems Arise For NASA's Ares 1 Rocket, SpaceRef

"NASA has run into some problems with the design of its new Ares 1 launch vehicle - problems that could affect its ability (as designed) to safely launch its human cargo into space. According to NASA sources, the Ares 1 first stage, as currently designed, would produce a frequency of 25 Hz at liftoff. The concern is that this oscillation could shake the Ares 1 upper stage and Orion capsule designed to carry human passengers, causing considerable damage and that it could also adversely affect the Guidance, Navigation, and Control avionics in the rocket's Instrumentation Unit."

Editor's note: According to NASA ESMD PAO:

"the Ares I first stage PDR has been moved to late summer or early fall of 2008 in order to better synchronize first stage activities with those at the vehicle system level and Constellation Program schedules, but this change is not expected to affect any test flight dates."
