There Are Blueberries on Mars. Sort Of. – Live Science
It was just a few months after NASA’s Opportunity rover touched down on Mars in 2004 that it spotted a geological curiosity: tiny, iron-rich spheres scattered across the rock surface near the robot’s landing site. Snack-loving scientists working with the mission dubbed these objects “blueberries,” but the features were easier to name than to understand. Their recipe remains something of a puzzle. Trying to sort out the origins of these blueberries has always involved studying similar-looking spherical formations here on Earth. New research takes its inspiration from these terrestrial analogs to offer a new idea of the chemistry that may have gone … Read more
