Problem of the survival of microorganisms under conditions simulating those on Mars

An aqueous suspension of microorganisms was placed in sand which was enriched by organic substances. Test tubes with sand were placed open into a low pressure chamber of a photostat device, where they were kept for 2-14 days in an atmosphere of carbon dioxide at a pressure of 10 mm Hg. The temperatu...
