Abstract:

Once every one-hundred and seventy-nine years the outer planets of the solar system – Jupiter, Saturn, Uranus, Neptune, and Pluto – align uniquely for exploration by unmanned spacecraft. Thomas Jefferson was the first President to have the opportunity to take advantage of this remarkable positioning of the outer planets, the second was Jimmy Carter.
