      Why the Moon Next?


      • Its close (3 days) and accessible (as near as
        GEO)
      • Alien yet familiar; Earth is visible to crew and
        TV audiences
      • Moon can be reached with existing or derived
        launch systems
      • Transport system to Moon can also access
        GEO, cis-Lunar, Earth-Sun Lagrangians, and
        some asteroids
      • Retire risk to future planetary missions by re-
        acquiring experience and testing with lunar
        missions
      • Development of lunar resources has potential

        to be a major advancement in space logistics

        capability

      • Advance science, improve engineering state-
        of-the-art, inspire country
