Setbacks Cast Doubt On NASA's Ares Project 255

stoolpigeon writes with this excerpt from an Orlando Sentinel article about the Ares program, which paints a bleak picture of the program's future: "Bit by bit, the new rocket ship that is supposed to blast America into the second Space Age and return astronauts to the moon appears to be coming undone. First was the discovery that it lacked sufficient power to lift astronauts in a state-of-the-art capsule into orbit. Then engineers found out that it might vibrate like a giant tuning fork, shaking its crew to death. Now, in the latest setback to the Ares I, computer models show the ship could crash into its launch tower during liftoff. "

The online article on "VOLCANOES, MANTLE PLUMES, and HOT SPOTS" linked to in the weblog mentions that hotspots can occur on plate boundaries.
