Mercury map,1977. Part of the cratered surface of Mercury as shown in a 1977 map issued for NASA by the National Geological Survey in the USA. Mercury's surface includes heavy cratering,showing that it has been geologically inactive for billions of years. Initial maps of Mercury were made based on the data received from the 1975 Mariner flyby. The planned MESSENGER mapping mission (2011) will allow more detailed maps to be produced. Other features seen on Mercury include Dorsa (ridges),Montes (mountains),Planitiae,(plains),Rupes (escarpments),and Valles (valleys) | |
