An international team of space physicists reports that Mars is constantly losing part of its atmosphere to space as a result of pressure from solar wind pulses. Their new study in Geophysical Research Letters should help scientists better understand the evolution of Mars's atmosphere. The researchers analyzed solar wind data and satellite observations that track the flux of heavy ions leaving Mars's atmosphere. Results of the analysis showed that Mars's atmosphere does not drift away at a steady pace; instead, atmospheric escape occurs in bursts. read more
