Description:
The paper discusses the concept and the current baseline configuration of a reusable solar sail vehicle using light pressure for propulsion. The range of characteristic accelerations which solar sail vehicles might achieve during early years of operation is estimated to be from 0.2 to 1.3 mm/sq sec, with overall sail efficiency about 80 to 90%. Operating without the expenditure of propellant, the vehicle has the potential of delivering large payloads throughout the solar system. Detailed attention is given to various possible missions of the solar sail vehicle operating as an Interplanetary Shuttle. The vehicle may deliver payloads to the inner planets, asteroids, short period comets, or sun polar orbits and then return to earth, possibly with samples. It may also be used for outer planet missions or solar system escape. An 800-m sail may return samples totaling 200 kg from Mars and deliver them to an earth orbital laboratory. The first mission for the solar sail may be rendezvous with Halley's comet in 1982.
