The purpose of the analysis reported was to compile as much as possible by way of characteristic data (theoretical/hardware) concerning the 9 listed propulsion concepts, to include these in mass and cost models, in conjunction with a generally applicable transfer vehicle architecture. In order to perform a system analysis employing three completely different mission scenarios, propulsion system mass and cost models were gathered and determined. Concepts like liquid oxygen/liquid hydrogen electrostatic and magnetoplasma propulsion, nuclear thermal, solar thermal, laser thermal, and mass driver reaction engine propulsion, as well as solar sails and aerobraking were considered. Considerations with regard to service life and reliability were taken into account. Clear advantages, especially the lowering of transport costs in near Earth and cis-lunar orbits, are expected with the implementation of solar thermal propulsion. Electric propulsion systems promise advantages in the transfer of large payloads, especially in interplanetary operations. The utilization of laser thermal propulsion between lower Earth orbit and lunar orbit is preferred only when the existing laser stations can be used for additional applications.
