The Ancient Cratered Terrain,le a superficial look at a few Viking images of the upland hemisphere suggests a lunar-like surface, closer inspection reveals not only a difference in the nature of the cratering record but also in the morphology of the craters themselves (Fig. 6.1).

The first two of these were published in 1609 after the latter realised, having calc

The Present Face of Mars,; for instance, the whitish spot of Nix Olympica represents the massive volcano, Olympus Mons, while the impact basins of Hellas and Argyre are clearly visible with a telescope as being paler in hue than the surrounding uplands. In consequence, some of the old names from telescopic maps have survive

What is known is the mean density which is 3930 kg m., and the mass which is only about one-tenth that of the Earth.

Early impact cratering left a very obvious imprint on both worlds while subsequent impact erosion severely degraded the more ancient craters and basins.
