SUMMARY:The Physics of Space Weapons\, Physics Department Colloquium\,
  David Wright\, Union of Concerned Scientists and MIT
DESCRIPTION:U.S. interest in new military uses of space has increased 
 in the past few years\, driven in part by the important role satellite
 s have played in recent conflicts. New uses of space being considered 
 include basing weapons in space to attack targets on the ground and in
  space\, and developing weapons to attack satellites. This has led to 
 an international debate about how space should be used and whether suc
 h activities should be limited. This issue took on added urgency after
  the Chinese test of an anti-satellite weapon in January 2007. Unfortu
 nately\, many of the discussions\, both by weapons proponents and oppo
 nents\, reflect a lack of understanding of fundamental physics concept
 s that are important for the debate. This talk will give an introducti
 on to the current debate\, and will show how basic principles of mecha
 nics and orbital dynamics can have important implications for these is
 sues. It will also discuss briefly our recent work on the creation of 
 orbital debris by anti-satellite weapons.
