Abstract
Most people love a little traveling, but this year we celebrate the anniversaries of some of the greatest voyages of exploration. It was 50 years ago on 20 July 1969 that mankind, in the person of Neil Armstrong, first walked on another celestial body, the Moon, with the Apollo 11 mission — certainly a pinnacle step in human accomplishment. We anticipate that a woman, hopefully a geoscientist (such as Harrison Schmitt, the second-to-last man on the Moon), soon will accomplish a similar feat. Perhaps, less well remembered is 500 years ago on 20 September 1519 when Ferdinand Magellan began in Spain what finished as the first circumnavigation of Earth, further mapping the New World ( Figure 1 ), providing another link between East and West, and capturing the vast oceans under his sail.
