Climate models used to explain formation of Mars valley networks > http://phys.org/news/2015-10-climate-formation-mars-valley-networks.html > The extensive valley networks on the surface of Mars were probably > created by running water billions of years ago, but the source of > that water is unknown. Now, a team of Penn State and NASA researchers > is using climate models to predict how greenhouse warming could be > the source of the water. > > "Everyone is looking for life on Mars, and if Mars was habitable > early on as indicated by flowing water, then the chances of there > being some sort of life there now goes up," said Natasha Batalha, > graduate student in astronomy and astrophysics, Penn State. "Our work > involves using models to best estimate what was happening on the > surface of Mars 3.8 billion years ago." > > Previous studies analyzing craters support the idea of flowing water > on early Mars but still unknown is how surface warming occurred to > melt that water and how much water was really there. > > "If we compare some of these valleys on Mars to what we know on > Earth, for example the Colorado River, then they look to be the same > width," said James Kasting, Evan Pugh Professor of Geosciences, Penn > State. "We know how much water it took to carve the Grand Canyon > based on five to six million years of rainfall, which is estimated to > be about three to six million feet (of rainfall)." -- sci.physics is an unmoderated newsgroup dedicated to the discussion of physics, news from the physics community, and physics-related social issues.
