      SUMMARY
      The purpose of this Position Paper is to briefly review what is now known
      about the threat to Earth posed by close approaching asteroids and comets
      (called Near Earth Objects or NEOs).

      -[snip]----

      Following are the principal AIAA recommendations:

      1. Create an organization within the U.S. government responsible for
      planetary defense.

      2. Extend the Spaceguard Survey, currently focused on finding and
      cataloging 1-km-class objects and larger, to include finding and
      cataloging 100-m-class NEOs and larger.

      3. Develop and fund ground-based techniques as well as missions to several
      asteroids to gather information that contributes to designing deflection
      missions.

      4. Conduct mission design studies to characterize requirements for short-,
      medium-, and long-term missions.

      5. Conduct flight tests to demonstrate the ability to change a NEO?s orbit.

      6. Sponsor research to assess the political, social, legal and disaster
      relief consequences of a serious NEO threat, mitigation effort, or
      possible impact.
