Glow discharges generated by friction within Martian dust clouds are proposed to explain the apparent absence of carbonaceous material on the planet's surface. An experiment to simulate the atmospheric circulation of fine siliceous particles under the various low-pressure conditions that may be prevalent on Mars is found to produce several types of glow discharge. Since glow discharge, like solar utraviolet radiation, effectively removes organic trace materials from a medium, these two mechanisms may be responsible for effacing organic material from the Martian surface. Furthermore, the accumulated chemical effects of glow discharges, including the formation of powerful oxidants, may have a role in accounting for the Martian coloration and the negative results of Viking experiments involving microorganisms.
