An oblique view of an area of the lunar farside, looking southward, as photographed from the Apollo 15 spacecraft in lunar orbit. The crater Zelinsky is in the near foreground at the edge of the picture. The circular, mare-like area in the center is the crater Thomson. Thomson is almost completely surrounded by Mare Ingenii. The approximate coordinates of the center of Thomson are 166 degrees east longitude and 32.2 degrees south latitude.
