The Moon is the nearest body to us in the Solar System, and as a consequence of the Apollo missions is the only extra-terrestrial object that has yet been explored directly by humans. As a consequence of that exploration by both manned and unmanned spacecraft, we now know a great deal about our nearest celestial neighbor.
 "I believe that this nation should
commit itself to achieving the goal, before this decade is out,
of landing a man on the Moon and returning him safely to the Earth.
No single space program in this period will be more impressive to
mankind, or more important in the long-range exploration of space;
and none will be so difficult or expensive to accomplish." |
