NASA’s eye in the Martian sky has spotted evidence of dried-up, primordial rivers on Mars.
The space agency’s Mars Reconnaissance Orbiter captured a snapshot of another time, billions of years ago, when water flowed on the surface of a temperate Mars. NASA recently posted the image on its “Planetary Photojournal.”
“This image of ridges in Aeolis Planum tells a story of ancient rivers and a Mars very different to that of today,” NASA wrote online.
