Rotating spacecraft with flexible spike antennas located along their rotation axis can be seriously affected by instability problems. The Auroral Probe of the INTERBALL Project is a typical example of such an object. It is shown that magnetohydrodynamic (MHD) elements may be effectively applied for control of the spacecraft. In particular, by using MHD elements it is possible to stabilize the rotation of a spacecraft without reducing its angular velocity. It is important that the MHD control system does not have hinges and does not need any special fuel storage. Copyright © 2003 John Wiley & Sons, Ltd.
