"Signs of Ancient and Modern Glaciers on Mars Point to Possibility of Water Ice"

The discovery of a "relict glacier" on Mars suggests that surface water ice may still exist on the planet, even near the equator, which could have "significant implications for future human exploration." The glacier's imprint was likely preserved by volcanic activity in the area, and the discovery suggests that Mars may have had a more "watery" history than previously thought. However, more research is needed to determine if and how much ice may be preserved under the light-toned deposits where the glacier was found.
