Phobos 2 spacecraft photo of Martian moon Phobos

Combined optical & near infrared image of the Martian moon Phobos, seen against the background of the red Martian surface. The image was recorded by the 3-channel TV camera (VSK Fregat) on board the Soviet Phobos 2 spacecraft. Phobos is the innermost & larger of the two Martian satellites. It is roughly ellipsoidal in shape & measures 19 x 21 x 27 km. It orbits Mars every 7.65 hours & is located some 9380 km above the Martian surface. The two Phobos spacecraft were launched in July 1988. Contact with Phobos 1 was lost en route to Mars in October 1988, due to a controller error. Phobos 2 orbited Mars for 57 days before succumbing to computer failure in March 1989
