are proposed. Then a possible space station tether configuration is shown that could be used to control the initial station. It is then shown how the technique can be extended to the control of space stations of virtually any size. (G.L.C.)

Whether these changes will stabilize or achieve medical significance is not clear. Artificial gravity is the Physiological countermeasure, and the tether system represents an attractive approach to artificial gravity. The need for artificial gravity is examined. (B.G.)
