An unusual pair of craters on Mars formed when a moon broke apart before crashing into the planet’s surface about a billion years ago, a new study suggests.
The craters could hint at what lies in store for Phobos, a potato-shaped moon that is expected to smash into Mars millions of years from now.
The two craters, which lie about 12.5 kilometres apart, share the same oval shape and nearly the same west-east alignment.
