The moon may be divided into two major terrains: the Maria (dark lowlands) and the Terrace (brighthighlands). The contrast in the reflectivity (the capability of reflecting light) of these two terrains suggested to many early observers thatthetwoterrainsmighthave differentcompositions,andthissuppositionwas confirmed by missions to the Moon such as Surveyor and Apollo. One of the most obvious differences between the terrains is the smoothness of the Maria in contrast to the roughness of the highlands. This roughness ismostly caused by the abundance of craters: the highlands are completely coveredby largecraters (greaterthan 40-50 km indiameter),while the craters of the Maria tend to be much smaller. It isnow known that the vast majority of the Moons craters were formed by the impact of solid bodies with the lunar surface. Most of the near side of the Moon was thoroughly mapped and studied from telescopic pictures years before the age of space exploration. Earth-based telescopes can resolve objectsas smallasafewhundredmeters onthe lunarsurface.Closeobservationofcraters, combinedwith the way the Moon diffusely reflects sunlight, led to the understanding that the Moon is covered by a surface layer, or regolith, which overlies the solid rock of the Moon. Telescopic images permitted the cataloging of a bewildering array of land forms. Craters were studied for clues to their origin; the largewispy marks were seen. Strange,
