Mars' Satellite Phobos By Viking 1

The next image is a montage of three separate images taken by Viking 1 during one of its flybys of Phobos. The montage was created by Dr. Edwin V. Bell, II (NSSDC/Hughes STX Corp.), from images F854A81, F854A82, and F854A83 which are present on Vol. 30 of the Mission to Mars: Viking Orbiter Images of Mars CD-ROM set. The images were separately contrast enhanced and then montaged with Adobe Photoshop (tm). The images were taken from ranges between 613 and 633 km on 19 October 1978. The large crater (mostly in darkness) on the upper left of the image is the crater Stickney.
