NASA's Perseverance rover detected corundum, the mineral that comprises rubies and sapphires, in three Martian rocks examined with its SuperCam instrument near Jezero crater. Researchers believe the gems formed from meteorite impacts rather than plate tectonics as on Earth, marking the first discovery of corundum on Mars.
