GENERAL DYNAMICS / ASTRONAUTICS artist’s conception of a three-man Manned Astronautical Research Station (MARS) in operation 200 miles above earth. The station in orbit would be linked to a spent Centaur vehicle. The two bodies would rotate about each other, the resulting centrifugal force providing the necessary artificial gravity.
