We've seen everything from a Mars Reconnaissance Orbiter of a crater and valley that combine to look very much like a tadpole.to on Mars, but a larval-stage amphibian is a new one. This week, NASA shared a goofy image captured by the
NASA says the unusual shape comes from water carving out a valley as liquid flowed out of the crater. "We can infer that water is flowing outward because we have the necessary terrain-height information," the space agency says. Scientists have found evidence pointing to a distant watery past for the now-dry planet.
NASA isn't immune to the occasional flight of fancy when describing things seen beyond our world. The agency likened a blueberries."to "scratch marks" and describes circular formations found on the Red Planet as "
