Caption:

A field of bright rays--created by ejecta from a crater--radiating to the north (top) from off camera (lower right) is seen in this view of Mercury taken September 21 by Mariner 10. Source of the rays is a large new crater to the south, near Mercury's South Pole. Mariner 10 was about 48,000 kilometers (30,000 miles) from Mercury when the picture (FDS 166749) was taken at 2:01 p.m. PDT, just three minutes after the spacecraft was closest to the planet. Largest crater in this picture is 100 kilometers (62 miles) in diameter.

Background Info:

The Mariner 10 mission, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, explored Venus in February 1974 on the way to three encounters with Mercury-in March and September 1974 and in March 1975. The spacecraft took more than 7,000 photos of Mercury, Venus, the Earth and the Moon.
