Megafloods on Mars. 😃

Swept Away

The end result — which the scientists identified using data from NASA’s Curiosity rover — is that the floods shaped the surface of Mars into 30-foot-tall ripples of rock and dust. The water itself is long gone — but the scientists speculate that the floods means the planet may have been inhabitable at the time.

“Early Mars was an extremely active planet from a geological point of view,” study coauthor Alberto Fairén, an astrobiologist visiting Cornell, said in the release. “The planet had the conditions needed to support the presence of liquid water on the surface — and on Earth, where there’s water, there’s life.”
