Phobos - Viking 1 Orbiter

Linear features and crater chains on Mars' moon Phobos

Viking 1 Orbiter image of Mars' satellite Phobos. The linear features and crater chains from lower left to upper right are believed to be results of the impact which formed Stickney crater, which is just off the image to the bottom left. The image is 9 km across and north is at 10:30. The small crater at the center of the image is located at about 20 N, 15 W. (Viking Orbiter 343A15)
