NASA Rover Discovers Liquid Water 'Ripples' Carved Into Mars Rock
Scientists have discovered evidence of ancient, shallow lakes on Mars that once had liquid water exposed to the atmosphere, challenging previous theories that all Martian water was covered in ice.

Live Science reports: The patterns, which were photographed by NASA's Curiosity rover, are known as wave ripples -- minute ridge-like structures that form along the shores of lakebeds. "The shape of the ripples could only have been formed under water that was open to the atmosphere and acted upon by wind," study first author Claire Mondro, a sedimentologist at CalTech, said in a statement. Both dry lakebeds appear to have formed around 3.7 billion years ago, indicating that Mars had an atmosphere dense and warm enough to support liquid water for longer than previously thought -- which could have intriguing implications.
