Water Isn't Actually Flowing on Mars, Suggests New Result
Two years ago, NASA made the baffling announcement that the surface of Mars featured running water systems.
This observation was based on the appearance of seasonal flows, called “recurrent slope lineae” or RSL.
Obviously everyone’s first conclusion was that life existed on the planet. But a new study seems to have cast doubt on whether water was truly the cause of these features. Maybe it was sand all along.
In a new study published in Nature Geoscience, study authors wrote, “Flowing liquid water in the current Martian climate has always been an extraordinary claim. The observations and interpretations presented here suggest that RSL are no longer extraordinary evidence.”
