Martian Moon Eclipses Martian Moon

Mars has two moons, Phobos and Deimos, and they can eclipse each other. This video, captured by the ESA's Mars Express orbiter, shows Phobos, the larger and closer moon, passing in front of Deimos, the smaller and more distant one. Such events are rare to witness even from the Martian surface. From space, we get a unique perspective on this celestial ballet.
