The majority of Mars' valleys were carved by ice sheets, not flowing rivers, calling the Red Planet's supposed warm, watery past into question, according to new research published Monday in Nature Geoscience. "Valley networks on Mars have historically been interpreted as surface water flows, either sourced by surface liquid water or by ground water," study lead author Anna Grau Galofre
