Abstract
In this report, we investigate the problem of mitigating the threat from an earthimpacting
object. We provide a brief historical perspective of the subject, then focus
on the problem of deflecting an object, with a unique new viewpoint leading to
the development of a fundamental definition of the problem. Within the context of
this fundamental deflection problem, we define several typical scenarios, each of
which leads to classes of potential optimization problems to be solved. Many deflection
strategies have been proposed in the literature, and we describe several of
these, with emphasis on a classification that complements the fundamental definition.
