NASA Has Just Released Breathtaking New Photos of Mars And They Are Marvellous

Researcher Dr. Mary Bourke from Trinity College Dublin have discovered a patch of land in an ancient valley in Mars' Lucaya Crater that appears to have held water in the not-too-distant past, making it a prime target to search for past life forms on the Red Planet. Signs of water past and present pop up everywhere on Mars from now-dry, wriggly riverbeds snaking across arid plains to water ice exposed at the poles during the Martian summer. (Striations exposed on the surface between Martian sand dunes (one pictured at top) in Lucaya Crater indicate fluctuating levels of salty groundwater. At a we see possible cross beds which are tilted layers of sand within larger layers deposited by wind or water. At b, dark and light strata are similar to that exposed in the dune at top and resemble the striations seen in the Namib Desert on Earth. The photo was taken by NASA's Mars Reconnaissance Orbiter in infrared, red and blue light. Credit: NASA/JPL-Caltech)
