Since its arrival on the Martian surface five years ago, NASA’s Perseverance rover has been busy scouring the Red Planet for signs of life and evidence of Mars’ watery history. Now, thanks to its continued exploration, NASA might know exactly where to look for evidence of life on Mars, and it all begins with quartz crystals.

NASA’s Perseverance rover has uncovered high-purity quartz crystals on Mars, a discovery that could reshape the search for ancient life on the Red Planet. The crystals, along with other minerals such as opal,

NASA’s Perseverance rover found large crystals of quartz with a high purity on Mars, which probably had to have formed in the presence of hot water

Scientists may have uncovered a promising new method to detect ancient life on Mars. A recent study suggests that microbial fossils could be preserved in sulfate minerals like gypsum, which are abundant on the Martian surface.
