One of the mosaics shows a deposit dubbed “Skrinkle Haven,” where flowing water carved rock layers that remain billions of years later. Previous observations by the Curiosity rover, which landed on Mars in 2012 and is exploring Gale Crater about 2,300 miles (3,700 kilometers) away, revealed evidence of shallow streams rather than powerful rivers. Scientists have long been curious about the diverse types of waterways that once existed on Mars more than 3 billion years ago, when the planet was warmer and wetter. It’s the first time scientists have seen environments such as this on Mars. The curved layers of the fan suggest flowing water shaped them, and the latest images taken by the rover point to a deeper and more rapidly moving river than scientists expected on Mars. So here in Jezero, we have evidence of lakes, deltas and ancient rivers.” “With the rover, we’re actually moving through different environments that once had water associated with them. “This fan really represents the main history of water in the crater,” Katie Stack Morgan, Perseverance’s deputy project scientist at NASA’s Jet Propulsion Laboratory, told CNN.
