Curiosity's ChemCam Views a Rock Shaped Like Coral

NASA's Curiosity Mars rover used the Remote Micro Imager, part of its ChemCam instrument, to view this wind-eroded rock shaped like a piece of coral on July 24, 2025, the 4,609th Martian day, or sol, of the mission. Curiosity has found many rocks like this one, which were formed by ancient water combined with billions of years of sandblasting by the wind. This particular rock is similar to one seen by Curiosity's Mars Hand Lens Imager around the same time. Curiosity has found many small features like this one, which formed billions of years ago when liquid water still existed on Mars. Water carried dissolved minerals into rock cracks and later dried, leaving the hardened minerals behind. Eons of sandblasting by the wind wore away the surrounding rock, producing the unique shapes seen today. This common process, seen extensively on Earth, has produced fantastic shapes on Mars, including a flower-shaped rock. https://photojournal.jpl.nasa.gov/catalog/PIA26634
