New research indicates that, more than 3 billion years ago, seasons in Gale Crater on Mars were probably something like those in Iceland. The ancient Martian crater is the focus of a study comparing data from the Curiosity rover to places on Earth where similar geologic formations have experienced weathering in different climates. Iceland’s basaltic terrain and cool weather, with temperatures typically less than 38 degrees Fahrenheit, turned out to be the closest analog to ancient Mars. The s...
