Last week, the Perseverance Science Team discovered a strange rock on Mars consisting of hundreds of millimeter-sized spheres.The team is working hard to understand the origin of these spherical-shaped objects and their context within the Martian geology.Similar spherical formations have been observed on previous Mars missions, such as the "Martian Blueberries" and spherules in Yellowknife Bay.The different formation mechanisms of these spherules provide insights into the evolution and geological history of Mars.
