Mercury - Mariner 10

Global mosaic of Mercury, incoming view

Mariner 10 mosaic of Mercury taken during the approach to the first encounter. This mosaic was made of 18 pictures taken at 42 second intervals 6 hours before closest approach. The lower two-thirds of the visible portion is the southern hemisphere of Mercury. The resolution is about 2 km. The flat-floored crater just below the center of the frame, containing two smaller craters at its bottom right and left, is the 160 km diameter Petrarch. The light-floored crater surrounded by darker material at the upper left is Lermontov, diameter 160 km.
