This is a AIR FORCE INST OF TECH WRIGHT-PATTERSONAFB OH report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A691653. The abstract provided by the Pentagon follows: Asteroids with orbits intersecting earth pose varying levels of threat to mankind and our planet. A small object, ^100 m diameter, can wipe out cities the size of New York or San Francisco. Larger objects, >1 km diameter, impacting the Earth can have global, catastrophic consequences. Possible ways of preventing dangerous objects from colliding with Earth are presented in this investigation. Methods of asteroid mitigation fall into two general classes: deflection and fragmentation. Significant work has been done in both areas, but the majority of the numerical results have been for general types (i.e. sizes) of asteroids. This investigation will give numerical results for three real asteroids that get within ^0.04 AU of Earth or closer. Results are produced for a variety of techniques, both deflection and fragmentation, available for hazard mitigation.
