Scientists Solve Mars Water Mystery With a Thin Layer of Ice
New climate modeling suggests that small lakes on ancient Mars could have stayed liquid for decades, even in a generally cold environment. Small lakes on early Mars may have stayed in liquid form for many years, despite average temperatures that were far below freezing. Researchers at Rice University used a climate model redesigned for Mars [...]
Mars May Have Hidden Liquid Lakes for Decades, Beneath Just a Thin Layer of Ice
A new climate model suggests that ancient lakes on Mars may have survived for decades beneath thin layers of ice that formed and melted with the seasons. The findings help resolve a long-standing contradiction between geological evidence of water and models predicting a frozen planet. The study, led by Eleanor Moreland of Rice University, presents a solution rooted not in warmth, but in insulation. Rather than demanding Earth-like temperatures, …
On Mars there are numerous geological traces of former lakes and rivers. Nevertheless, it is unclear how these waters could survive at that time despite thin atmosphere and cold temperatures, now a new model provides a possible answer – at least for some of the lakes of early Mars. Therefore, a thin, wintry ice layer could have contributed to the water [...] The article Ice layer protected Mars lakes appeared first on wissenschaft.de.
