NASA’s Perseverance rover spotted an unusual striped rock, dubbed “zebra rock” or “Freya Castle,” on Sept. 13 in the Jezero Crater. The rock, about 8 inches across, features dark and light stripes, unlike any other known Mars rocks. Researchers are exploring possible explanations for its unique appearance. The discovery has sparked significant online speculation, with comparisons to Earth rocks like granite and marble. Perseverance team member Athanasios Klidaras noted the excitement and shared insights from scientists studying the rock.
