Scientific paper

Both silicon and iron oxides, which are two of the major constituents of lunar soil, have been shown to undergo vacuum reduction at pressures 10 orders of magnitude higher than would be encountered in interplanetary space; the vacuum reduction of other silicates found in extraterrestrial soils should also be possible, allowing the construction of space habitats and solar power systems, and the derivation of fuels for extended operations. Also evaluated is the purification of the metals thus obtained, using such space environment-compatible techniques as vacuum distillation, slagging, and zone refining.
