Ever wonder what Mars might have looked like billions of years ago? So do we! Today, the Martian surface is sorely lacking in stunning water views like this, but our Perseverance Mars rover is busy exploring Jezero Crater, where scientists believe about 3.5 billion years ago a lake and river delta may have flowed! The rocks in this photo adorn the shoreline of Lake Salda in Turkey, an area that scientists believe the #RedPlanet may have resembled billions of years ago. Formed over time by microbes that trap minerals and sediments in the water, this waterfront location provides some of the oldest known fossilized records of life on our planet. Scientists hope by studying microbial fossils on Earth, they might be better able to spot signs of microbial life from the water and sediments that flowed on Mars billions of years ago.
