Abstract
1. It is of interest to investigate the behaviour of the terrestrial microorganisms under artificial Martian conditions. This will help to verify the hypothesis concerning a possibility of life on this planet. 2. An artificial climate chamber enables one to expose microbial cells to a simultaneous effect of such factors as temperature, pressure, gas composition and insolation: a) Temperature regime is maintained automatically by means of an electronic mechanical programme device. b) A sealed chamber insures a permanent gas mixture pressure equal to 0.1 atm. c)The spectral composition of light source is close to that of the sun spectrum. d)The chamber enables to expose microorganisms on membrane filters with diameter of 23 mm or in special quartz cells of the same diameter size. 3. The preliminary experiments have shown that not all the terrestrial forms of microorganisms do survive under artificial conditions of the Martian summer.
