This image, from NASA's Mariner 10 spacecraft which launched in 1974, shows a scarp (upper left corner of the image) about 130 kilometers long cutting two craters (older crater is at extreme left corner, younger is diagonally below).

A scarp (upper left corner of the image) about 130 kilometers long cuts two craters (older crater is at extreme left corner, younger is diagonally below). The northwest rim of the younger crater (65 kilometers in diameter) has been offset about 10 kilometers by the scarp. This offset appears to have been caused by shortening of the crater due to thrusting of the eastern part of the crater over the western part. (See PIA02434for high resolution image of this crater rim offset.)

This image (FDS 27380) 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.
