Martian Lightning

Science News : Scientists say they have seen the first direct evidence of lightning on Mars, in the form of electrical discharges during a Martian dust storm.The finding has implications for human travel to the Red Planet and for studying possible origins of life on Mars, the authors say in a paper to appear in Geophysical Research Letters .It has been thought that lightning might be possible on Mars. Bits of dust rubbing against each other in one of the planet’s famous dust devils could charge up the particles the same way that running on a carpet charges up socks. All that charge could then be discharged in a zap, either as lightning or a shock.But catching Martian lightning in the act was difficult: The lightning bursts were too small to distinguish from the energy emanating from the planet itself. And the dust storms themselves obscured the faint glow that might have been visible from just above the red planet. Related Link Emission of non-thermal microwave radiation by a Martian dust storm
