NASA Mars MRO Image: Ice Flows in Crater Greg

Computer models used to forecast climate change on Earth have been validated on Mars, astronomers reported.

In this orbital photo from Nasa's Mars Reconnaissance Orbiter show ice flow features in ancient riverbeds on the south wall of crater Greg.

These computer programs accurately predicted Martian glaciers and other features on Earth's next-door planetary neighbour.
