caffiend666 writes "According to an AP New Article: "Engineers are concerned that the new rocket meant to replace the space shuttle and send astronauts on their way to the moon could shake violently during the first few minutes of flight, possibly destroying the entire vehicle.... NASA officials hope to have a plan for fixing the design as early as March, and they do not expect it to delay the goal of returning astronauts to the moon by 2020.... The shaking problem, which is common to solid rocket boosters, involves pulses of added acceleration caused by gas vortices in the rocket similar to the wake that develops behind a fast-moving boat...." Astronauts always desribed the shuttle ride as rocky until the SRBs fall off, I was wondering what would happen when they no longer had the counter-weight of the main tank and the orbiter."
