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_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_8_12.jpgMultiple Craters (HR)55 visiteAs Mariner 10 passed by Mercury on its 2nd encounter with the Planet on September 21, 1974, this picture (FDS 166850) of a large circular (about 350 Km or 220 mile diameter) basin was obtained near the morning terminator. The basin appears to have been flooded with the plain material and then subsequently cratered by numerous large events.
Filling of the basin, presumably by lava flows analogous to those of the lunar maria, partially inundated small craters which had formed along the basin rim (lower left) and in some places overflowed the basin rim and spilled onto the surrounding terrain (top).

m10_aom_11_20~0.jpgCrater and scarps (HR)55 visiteHigh-Resolution (HR) picture of a 65-Km diameter crater and the scarp transecting it's floor (to the left of this image). The scarp has a slightly terraced appearance which may be individual fault planes compromising an imbricate thrust fault.
This image (FDS 27464) was acquired during the spacecraft's first encounter with Mercury.

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.
