This image from ESA’s Mars Express shows a slice of Mars showing volcanoes, valleys, craters, clouds, and even a flying visit from Mars's largest moon, Phobos.
One of the most geologically interesting areas on Mars is the Tharsis region, a bulge with a height of over four kilometres, roughly the size of North America, and home to four of the tallest volcanoes in the Solar System: Olympus Mons (22 kilometres high), Ascraeus Mons (18 kilometres), Pavonis Mons (12 kilometres) and Arsia Mons (14 kilometres). In addition to numerous other striking landscape features, the approximately 28-kilometre-diameter Martian moon Phobos, which orbits the planet at an altitude of 6000 kilometres, can also be seen in the southernmost quarter of the image. Image taken on 19 October 2023 during orbit 25 000.
