Mars has two satellites, Phobos and Deimos. In August and September, 1998, the Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) had four opportunities for close fly-bys of the inner moon, Phobos. This spectacular view, taken from the MOC archives of over 123,000 images, shows the large crater, Stickney, toward the upper right. Grooves, or troughs, radiate outward from Stickney and are known from Viking and Mariner 9 images to be prevalent all over the surface of Phobos. Sunlight illuminates the scene from the upper right. Another view of Phobos from 1998 can be seen in: MOC2-66, 11 September 1998, "Phobos."
