Phobos - Viking 1 Orbiter

Linear features on Mars' moon, Phobos

Viking 1 Orbiter image of linear features on the surface of Mars' satellite Phobos. The features appear to be related to the formation of the crater Stickney, off the image to the bottom left. The sub-Mars point is just off the bottom left corner of the image, and the image, centered at 10 N, 330 W, is about 7 km across. North is at 11:30. (Viking Orbiter 246A05)
