m10_aom_20.jpgThe Southern Hemisphere of Mercury57 visiteThe Image Processing Lab at NASA's JPL Laboratory produced this photomosaic using computer software and techniques developed for use in processing planetary data.
The Mariner 10 spacecraft imaged the Region during its initial flyby of the Planet.

m10_aom_11_27.jpgDiscovery Rupes' Scarp (HR)55 visiteA limping Mariner 10 spacecraft was coaxed into a third and final encounter with Mercury in March of 1975.
Due to several problems with the aging spacecraft, only ~450 useful images of the Planet were acquired, though many are at significantly higher resolution than previous encounters.
In this HR image (FDS 528884) the Sun is low to the horizon thus enhancing topographic features with prominent shadows.
As can be seen here, the surface of Mercury is heavily cratered similar to the Moon.

m10_aom_2_10.jpgThe "Antoniadi" Ridge of Mercury (HR)55 visiteAntoniadi Ridge, over 450 Km long, runs along the right side of this image. The ridge transects a large crater (80-Km in diameter) and in turn appears to be interrupted by an irregular rimless depression on the floor of the crater. This ridge also crosses smooth plains to the north and intercrater plains to the south of the large crater.
This image (FDS 27325) was acquired during the spacecraft's first encounter with Mercury.

m10_aom_19.jpgMercury's "Outbound" view59 visiteAfter passing on the darkside of the Planet, Mariner 10 photographed the other, somewhat more illuminated Hemisphere of Mercury.
The North Pole is at the top, two-thirds down from which is the Equator.
