Abstract

If it were feasible, given the warning time of an actual hazardous asteroid approach, to conduct the deflection in such a way as to place the asteroid in a region of phase space that does not yield a significant future impact risk (i.e. a "safe harbor") with the Earth, this should certainly be done. In this work a numerical method is used to optimize all of the relevant mission parameters for a spacecraft to deflect an asteroid via impact. The objective of the numerical optimizer is to maximize the initial deflection obtained while assuring that subsequent close approach distances of the asteroid to the Earth are only increased by the initial deflection.
