Mars’ Gale crater had seasons similar to Iceland 3 bn yrs ago: Study

A Rice University study has said Mars’ Gale crater had seasons and terrain that were close to that of Iceland’s over three billion years ago.

Scientists compared data from NASA’s Curiosity rover to places on Earth where similar geologic formations have experienced weathering in different climates. The makeup of sand and mud in Iceland was the closest match to Mars.

The findings that shocked researchers was the little weathering of rocks on the Red planet despite being there for more than three billion years.
