Curiosity rover finds evidence of ancient megafloods on Mars

Previous images of large channels on Mars and giant wave-like features on its surface called “megaripples” indicate that the planet suffered from catastrophic floods in the past. Now, a team of scientists has used data gathered by the Curiosity rover to prove that megafloods swept across the Gale crater around 4 billion years ago. “We identified megafloods for the first time using detailed sedimentological data observed by the rover Curiosity,” said Alberto G. Fairén, co-author of the paper published by Nature. “Deposits left behind by megafloods had not been previously identified with orbiter data.”
