This picture of the Martian moon Phobos shows an object whose surface has been bombarded by solar system debris over the course of its life. The series of straight lines that run from the upper left to the center of the moon are striations. These striations are thought to be fractures created by the event that formed Stickney Crater. Stickney Crater is about 10 kilometers in diameter. The average diameter of Phobos is only 22 kilometers. Phobos is too small for gravity to form it into a sphere. Phobos is actually somewhat potato shaped measuring 27 by 22 by 18 kilometers in diameter.

Source Image Background

The source image of Phobos was acquired by the Mars Global Surveyor Narrow Angle Camera in June 2003.

Image Processing

Adobe Photoshop was used to create this false color image. In addition to noise removal, contrast enhancement, and the application of a subtle false color, additional manipulations were performed to enhance the surface texture of the moon.
