A new “water map” of Mars could offer fresh clues about the planet’s past — and potential landing spots for the future. Researchers from the European Space Agency (ESA) spent a decade developing the map from data collected by two Mars orbiters. They found hundreds of thousands of areas containing aqueous mineral deposits, which are created though interactions between rock and water. As the minerals still contain water molecules, they could show locations where we can extract water for human bases on the planet. These outcrops may also provide ideal sites for exploring whether life once began on Mars. The map…
