The surface of the planet Mercury has been divided into fifteen quadrangles, designated H-1 to H-15 (the 'H' stands for

albedo features An albedo feature is a large area on the surface of a planet (or other Solar System body) which shows a contrast in brightness or darkness (albedo) with adjacent areas. Historically, albedo features were the first (and usually only) features to b ...
, as these were the most prominent features visible before mapping was carried out by spacecraft. The mapping carried out with the images obtained by the '' Mariner 10'' flybys in 1974 and 1975 led to nine of the quadrangles being renamed for newly mapped prominent features. The remaining six quadrangles were completely unmapped by ''Mariner 10'' and were still referred to by their albedo feature names. Following the arrival of '' MESSENGER'' in orbit in 2011, these six quadrangles were mapped and renamed. The base mosaic used in the new maps was produced with orbital images by the MESSENGER Team and released by NASA’s Planetary Data System on March 8, 2013. This global mosaic includes 100% coverage of Mercury’s surface.
