sense at the time, larger amounts of hydrogen may be produced for propellant use, water manufacture, etc. • Develop the ability to produce construction materials in support of an expanding lunar outpost. This can have a phased “marketing plan” similar to those above. Start with very low-tech, “dumb”, non-critical uses, such as landing pads to minimize blast ejecta (dust) during landing and take-off, paved areas near the airlock for initial “brush off' of the suits for primary dust control, walls for non-pressurized structures to provide some thermal control, etc. • Develop lunar mining capability so that real production can be done robotically. This digging unit should be tested very early, perhaps on the second visit to the lunar outpost. An early task might be to use it to provide radiation protection for the outpost by covering the module with regolith. • Demonstrate the extraction of metals from oxygen-production by-products. • The search for asteroids should continue to identify likely candidates for eventual resource evaluation and use. Spectroscopic analysis, and eventually a sample return mission, should be attempted if a likely candidate is found. A near-term mission to do reconnaissance of the Moon and an asteroid, entitled Clementine, is planned for a 1994 launch.
