NASA's Curiosity rover is back at it again with another Mars discovery that could prove the existence of water on the Red Planet. This discovery is none other than a extremely good-looking rock.
While rocks are basically everywhere on Earth and us humans don't really pay much attention to them, NASA scientists are the complete opposite for rock discoveries on Mars. NASA's Curiosity rover is currently located in the Gale Crater and has recently discovered a new rock that could shed some light on whether or not the Red Planet harbored or still harbors water.
The rock has been nicknamed "Strathdon" and its features are scale-like which could suggest that Mars once had flowing water that eroded this rock at different periods of time. Each of the levels of scales have been estimated to be periods of time when Mars once went from wet to dry - forming a rocky layer that we can see above. Valerie Fox of Caltech has said "We're seeing an evolution in the ancient lake environment recorded in these rocks. It wasn't just a static lake. It's helping us move from a simplistic view of Mars going from wet to dry. Instead of a linear process, the history of water was more complicated."
