High-resolution picture of a 65-kilometer diameter crater and the scarp transecting its floor (lower left corner of this image). The scarp has a slightly terraced appearance which may be individual fault planes compromising an imbricate thrust fault.(See PIA02432 for another image of this scarp and crater.)
This image (FDS 27464) was acquired during the spacecraft's first encounter with Mercury.
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.
