Mercury - Mariner 10

Global mosaic of Mercury, outgoing view

Mariner 10 mosaic of Mercury taken as the spacecraft was outbound after the first flyby. This mosaic was made up of 18 pictures, taken about 6 hours after closest approach. The north pole is at the top, and the equator is about two-thirds down from the top. The resolution is about 2 km. Half of the Caloris Basin is visible at the terminator on the left, just above the middle of the image. The bright ray crater at the upper right is the 45 km diameter Degas.
