Abstract:

Spacecraft powered by solar thermal propulsion engines will be able to provide the velocity change required to economically maneuver large payloads from one orbit to another or to perform interplanetary missions. This innovative concept, when applied, will double the efficiency of currently used LH2 - LO2 chemical upper stages. Solar thermal propulsion uses the suns energy to heat a low molecular weight working fluid such as hydrogen to very high temperatures 3,000 K. The stored thermal energy is then converted to kinetic energy as the working fluid exits a diverging nozzle.
