CRISM image: phyllosilicates in a Tyrrhena Terra crater rim
This image shows layers clays and clay-like minerals called phyllosilicates that are exposed in Tyrrhena Terra, part of Mars’ ancient, heavily-cratered southern highlands. Tyrrhena Terra is roughly 2,300 kilometers (1,430 miles) across, about the size of Earth’s continent of Antarctica! … Continue reading

Martian surface: icy, cold, and dry for 4 billion years
Maybe the warm and wet environment on early Mars that scientists have long proposed wasn’t at the surface, but rather buried in the crust. That’s one of the conclusions of a new review that looks at Martian clay minerals and … Continue reading
