Intercrater Plains and Heavily Cratered Terrain - First Encounter

Jan. 18, 2000
Intercrater plains and heavily cratered terrain typical of much of Mercury outside the area affected by the formation of the Caloris basin are shown in this image taken during the NASA's Mariner 10's first encounter with Mercury in 1974.

Intercrater plains and heavily cratered terrain typical of much of Mercury outside the area affected by the formation of the Caloris basin are shown in this image (FDS 27488) taken during the spacecraft's first encounter with Mercury. Abundant shallow elongate craters and crater chains are present on the intercrater plains. Large tract of intercrater plains centered at 3 degrees N, 20 degrees W. Prominent scarp Santa Maria Rupes cuts both intercrater plains and old craters. North is to the top of this image which is 200 kilometers across.

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.
