Scientists now know exactly where to look for fossils on Mars – BGR



Nobody knows for sure whether life ever took root on Mars or not. The dry, dusty planet does not seem to be a particularly hospitable place these days, but things were probably quite different a few billion years ago. Well, a new study suggests that if we're looking for Mars fossils, there's a particularly promising place to look for.

The study, which was led by a researcher from the University of Edinburgh, was published in the Journal of Geophysical Research . It focuses on some very specific places on the red planet where fossils are likely to be, rocks in the vicinity of long-dead lakes, and exploits the knowledge of fossil hunting here on Earth to give the best chance to the Mars researchers To find evidence of Martian life

"The Martian surface is cold, dry, exposed to biologically harmful radiation and is apparently barren today," said the research team, which included members of NASA's Jet Propulsion Laboratory and scientists from Brown, MIT and Yale belong to others ̵

"However, there is clear geological evidence of warmer, wetter intervals in the past that could have supported life at or near the surface, and this evidence has motivated the National Aerospace Authority and the European Space Agency to search for remnants or traces prioritizing early Mars organisms in upcoming missions. "

Against this backdrop, scientists propose mud and clay on the shores of the ancient Marsseen is probably a good place to find fossils. Because the damp mud hardened to rock over millions of years, he probably gained some living evidence when something wandered around on the surface at that time. The silicic acid and the iron-rich composition of the rocks also facilitate the conservation of fossil evidence, according to the researchers.

"There are many interesting rocks and outcrops on Mars where we would look for fossils," Dr. Sean McMahon from the University of Edinburgh noticed. "But since we can not send rovers to everyone, we have tried to prioritize the most promising deposits for the best information available."

Let's hope you find something interesting!
