More Ares I Concerns - and Solutions

More rumblings over Ares I; Is the stick dying? , Orlando Sentinel

"There are rumblings of discord in the NASA family over the agency's troubled Ares I moon rocket. According to well-placed sources inside NASA, the astronaut office is deeply unhappy with the design of Ares as it emerges from an important review that is in the process of being finished up now. The concern is so great, the sources say, that there is some talk at the highest levels of NASA about the possibility of ditching the Ares, with its unconventional stick-like solid rocket booster first stage, in favor of a more conventional rocket design - one that sounds like the shuttle launch system without the shuttle."

Editor's note: NASA sources report that a week or so ago the Ares 1 PDR Board pulled a presentation on thrust oscillation solutions because of concerns voiced by the Astronaut Office. At this point the favored solution seems to be heading for "Option B - Active Pulsing RCS Plus Single Plane Isolation" which involves using thruster packs that are aimed upward on the aft end of the first stage plus hardware at the upper end of the first stage to isolate/dampen loads.
