produce a catalog that is 90% complete for potentially hazardous
objects (PHOs) larger than 140 meters." --NASA NEO SEARCH

http://neo.jpl.nasa.gov/neo/report.html NASA has released a
technical report on potential future search efforts for near-
Earth objects after a year of analysis by scientists working on
this issue. This Science Definition Team was chartered to study
what should be done to find near-Earth objects less than 1
kilometer in size. While impacts by these smaller objects would
not be expected to cause global devastation, impacts on land and
the tsunamis resulting from ocean impacts could still cause
massive regional damage and still pose a significant long-term
hazard. In 1998 NASA commenced its part of the "Spaceguard"
effort, with the goal of discovering and tracking over 90% of
the near-Earth objects larger than one kilometer by the end of
2008. An Earth impact by one of the
