Phobos, the larger of Mars’s two moons, as imaged by the HiRISE camera on NASA’s Mars Reconnaissance Orbiter. The moon measures roughly 20 km in diameter and its most prominent feature is the 9-km-wide Stickney crater. Phobos will be explored by the Martian Moons eXploration (MMX) mission that was launched on 19 October 2026. The spacecraft will reach its target in 2029 and return samples to Earth in 2031. The MMX mission is led by JAXA (Japan Aerospace Exploration Agency), with participation from NASA, CNES (France), DLR (Germany), and the European Space Agency (ESA).
