Asteroid Impacts Could Have Warmed Ancient Mars

Katherine Kornei, Science Writer by Katherine Kornei 17 April 202317 April 2023

Hydrogen released during large impacts might have boosted Mars’s surface temperature above freezing for thousands or even millions of years, enabling liquid water to flow over the Red Planet.
