Scientists may have found the best place for humans to land on Mars

Hidden ice beneath Mars’ surface may mark the spot where humanity first sets foot on the Red Planet. A newly identified region on Mars may hold the key to future human landings. Researchers found evidence of water ice less than a meter beneath the surface, close enough to be harvested for water, oxygen, and fuel. The location strikes a rare balance between sunlight and cold, helping preserve the ice. It could also offer clues about whether Mars once supported life.

Before humans can make the long trip to another world, scientists must identify a safe and practical place to land. New research led by a University of Mississippi scientist suggests one region on Mars may meet many of the requirements for future human missions.

Site of Martian Lakes Might Have Been Linked to Ancient Habitable Environment

Perspective views of (top) the floor of a basin where Rodriguez and others propose in this investigation that shallow lakes could have formed within the last few tens of millions of years, and (below) the floor of a proposed Martian analog high mountain lake in the Tibetan plateau, where Rodriguez will conduct a field investigation this coming summer. The arrows in both panels identify similar ridges that surround the basin’s floor. In the Tibetan lake case, the ridges are thought to form as sediments are pushed outwards by the freezing waters. These types of ridges might be diagnostic shoreline feature of lakes that formed under extremely cold and dry Martian conditions...
