  Boston MA (SPX) Dec 05, 2024 Dry river channels and lake beds on Mars point to the long-ago presence of a liquid on the planet's surface, and the minerals observed from orbit and from landers seem to many to prove that the liquid was ordinary water. Not so fast, the authors of a new Perspectives article in Nature Geoscience suggest. Water is only one of two possible liquids under what are thought to be the conditions present on ancient Mars. The other is liquid carbon dioxide (CO2), and it may ac ... read more |
