NASA’s Mars Perseverance Rover discovered a unique “zebra rock” in Jezero Crater, featuring black-and-white stripes unlike any seen on Mars before. Dubbed “Freya Castle,” the 20 cm rock’s texture suggests igneous or metamorphic origins. The rock likely rolled from a higher location, sparking excitement for potential new discoveries. Perseverance, which landed in February 2021, is currently climbing Jezero’s slopes in its fifth science campaign, seeking signs of ancient life and Mars’ early history.
