Mars was once a warmer, wetter place with flowing water and glaciers

Summary

Nutrition label

92% Informative

Scientists from the Planetary Science Institute examined subglacial melting in and around a mid-sized crater in the northern Arabia Terra region and the neighboring depression— the Heart Lake System .

They propose that a receding regional glacier created the depression in the region, leaving behind a proglacial lake with smaller glacial deposits within the crater, leading to subsequent meltwater and lake formation.

Their findings suggest that Mars may have been warmer than thought during the early Amazonian Period , which began 2.9 billion years ago .
