Mars Glaciers Were Slowed By Fast Drainage And Weak Gravity, Scientists Suggest

Mars may be a freeze-dried planet now, but once, it was supposedly (almost) another Earth, with flowing water that froze into hulking mountains of ice.

Because glaciers and ice sheets on Earth tend to slip and slide, they crawl across land and carve out stark geophysical features including linear grooves, ridges, and inverted hills. Scientists previously thought that glaciers on Mars stayed frozen in time due to the lack of similar features on the Red Planet. Planetary scientist Anna Grau Galofre of Laboratoire de Planétologie et Géosciences at Nantes Université in France led a study (opens in new tab) that found glaciers on Mars are on the move - they just happen to be extremely
