India, Nov. 27 -- Radiation, extreme cold, dust storms, not mention a lack of oxygen:There are plenty of things that can kill an astronaut on Mars. Now, researchers have added lightning to the list. Paris (dpa) - Thunderstorms aren't just an earthly phenomenon. Scientists have long known that electrical discharges occur in the atmospheres of Jupiter and Saturn. Now, for the first time, researchers have directly detected similar electrical activity on Mars. Measurements from NASA's Perseverance rover show that swirling dust on the Red Planet can generate static charge through friction. On Wednesday, scientists reported in the journal Nature that lightning risks will need to be considered when planning future crewed missions. On Earth, and li...
