The Perseverance Mars rover has collected a rock sample on Mars unlike any other it has picked up so far.
NASA's Perseverance rover is currently exploring hills and rocky outcrops along the rim of Jezero Crater, where it has been collecting rock samples to reveal the area's geological history. This week, NASA announced that the robotic explorer picked up a "one-of-a-kind treasure" in the form of a 1.1-inch (2.9-centimeter) rock sample from an area known as "Silver Mountain."
