Ancient Mars may have been too cold for liquid water

Ancient Mars may have been too cold for liquid water

April 16, 2014

By simulating hundreds of impacts in Mars' equatorial region, a team of scientists have determined that the ancient Martian atmosphere was likely too thin to support flowing liquid water on the planet's surface.  The team, including iPLEX researcher Jean-Pierre Williams, identified and catalogued hundreds of large craters near the Martian equator.  They then used a computer simulation to calculate what atmospheric density would have caused the range of craters observed.  They concluded that the Martian atmosphere was 150 times thickerAncient Mars may have been too cold for liquid water
