Moon: By going to the moon for extended periods of time, astronauts will search for resources and learn how to work safely in a harsh environment -- stepping stones to future exploration. The moon also offers many clues about the time when the planets were formed. Image above: Concept of a future moon landing.

Human exploration could provide answers to some profound questions. Beyond: As humans and robots work together exploring the moon and Mars, NASA spacecraft will continue to send back scientific data from throughout the solar system, laying the groundwork for potential human journeys.
