Scenarios and motivations for exploration, settlement, and exploitation of Mars are explored. Mars has an atmosphere that contains enough oxygen to extract breathing gases, and the soil is mineralogically rich in elements suitable for the manufacture of construction materials, fuels, and soil for growing plants. The location of Mars also serves as a gateway to the asteroids, which may be mined for raw materials. The Martian moons, Deimos and Phobos, are candidates for the development of asteroid mining techniques. The water supply on Mars consists of a 0.3 percent atmospheric concentration, the polar caps, and the potential for a deeply penetrating permafrost that extends to the lower latitudes. NASA has a design for a Mars mapper satellite that could locate the ground-frost areas of the entire planet. Ion-drive and solar-sail propulsive systems could provide power for the trip to Mars after the spacecraft have been assembled in earth orbit. The round-trip journey, plus landing, experimentation, and exploration, would last more than 2.5 yr. A larger data base is still needed to predict the health effects of the long journey in microgravity, isolation, and in exposure to occasional solar flare radiation.
