The media gave extensive coverage to Magellan's completion of its initial nine-month mapping of Venus and the amazing discoveries made. To date, 84 percent of Venus was mapped and in the second phase chief project scientist Stephen Saunders stated that 95 percent of Venus' surface was expected to be covered.
