Abstract:
The designs in this paper follow a sequence of ideas that start from the realization that manned Mars missions previously proposed owed a majority of their expense to the necessity of returning their crews to Earth. Most of the mass launched from Earth for a round trip Mars vehicle is in the propellant and structure for bringing the passengers back from Mars. The typical scenario requires launching ten kilograms of hardware and propellant from Earth to return one kilogram of payload from Mars.
