The Deflection Dilemma: Use Vs. Misuse of Technologies for Avoiding Interplanetary Collision Hazards
A system capable of deflecting a Near-Earth Object (NEO) out of a Earth-impacting trajectory could also be used to deflect a non-menacing NEO so it impacts the Earth.

Long-Range Consequences of Interplanetary Collisions
As Comet shoemaker-Levy 9 races toward its mid-July collision with the planet Jupiter, considerable public attention is being focused on catastrophic impacts with the Earth.

Radar Investigations of Earth-Approaching Asteroids
Much useful information about physical and dynamical properties can be obtained from radar observations of near-Earth asteroids that come within reach of the Arecibo and Goldstone telescopes.

Radar Investigations of Asteroids
Resolution of an asteroid's echoes in Doppler frequency and/or time delay provides 1-D or 2-D images, and hence direct measurements of the asteroid's size and shape even though its angular extent is tiny compared to that of the radar beam.
