Aerospace About stabilizing a space rocket with a pendullum

    About stabilizing a space rocket using a pendullum

    There exists a competition called Google Lunar X Prize whose main objective is sending a rocket to the Moon. One of the contenders, team ARCA, is ready to launch a rocket (not a Moon rocket) about which they claim to be passively stabilized in vacuum by the swinging movement of some pendulums (the lower stages of the rocket).

    A self explicative nice animation regarding the rocket of ARCA and its stabilization method can be downloaded from the following address:

    QUESTION: Do you believe that the stabilization procedure in the animation could work in vacuum, at least theoretically?

    One does not stabilize a craft by pendulum motion, and it should be obvious why.

    Rotational gyroscopic motion is the appropriate means.
