Mercury Revisited On the Cover: This mosaic of Mercury is compiled from images taken by Mariner 10 as it approached the planet on March 29, 1974. Mercury's ancient cratered surface can tell us much about the formation of the inner solar system. In the next decade, two new spacecraft will visit Mercury, the least-explored terrestrial planet, to continue the exploration Mariner 10 began almost 30 years ago.
