Use of Martian resources in a Controlled Ecological Life Support System (CELSS).
The exploration of Mars has long been considered as a major goal in the exploration of the Solar system.  The Space Station Freedom will make such missions feasible because it will provide a site for the assembly and launch of the large vehicles required.  Interest in manned visits to Mars often focus on the possibility of collecting information about the origin of that planet, & hence of the solar system, including the Earth.  Interest also involves the history of the planet, its past record of geological and fluvial activity, atmospheric and thermal history and surface chemical activity.  The latter is of particular interest to exobiologists who would like to seek evidence of pre-biological physical and chemical activity involving organic molecules.  Finally, there is interest in the possibility of planetary ecosynthesis, i.e. specific intervention in the evolution of Mars that could result in the development of a second habitable planet in the solar system.  The scenarios for visits and the establishment of bases on Mars are being developed now.  The intent of this paper is to consider various possibilities for crew life support on Mars and particularly to explore the use of Martian resources as life support materials.
