FUTURE PORGRAMS - ART CONCEPTS

S86-25375 (1986) --- (Artist's concept of possible exploration programs.) On Phobos, the innermost moon of Mars and likely location for extraterrestrial resources, a mobile propellant-production plant lumbers across the irregular surface. Using a nuclear reactor the large tower melts into the surface, generating steam which is converted into liquid hydrogen and liquid oxygen. Artwork by Pat Rawlings, of Eagle Engineering, Incorporated.
