Viking 1 Orbiter global view of the Martian satellite Phobos. The 10 km diameter Stickney crater is at the left, centered at 5 S, 55 W. The Mars facing point is at the bottom center of Phobos, and the north pole is at about 1:00 from this point. Radiating grooves and crater chains can be seen around Stickney. Phobos is roughly 20 km across in this image. (Viking Orbiter 357A64)
