Enhanced Kinetic Impactor for Deflecting Large Potentially Hazardous Asteroids via Maneuvering Space Rocks

The Enhanced Kinetic Impactor (EKI) concept is proposed to deflect large PHAs via maneuvering space rocks through the limitation of the ground-based launch capability, which can significantly increase the mass of the impactor.

Impact Hazard Protection Efficiency by a Small Kinetic Impactor

In this paper the ability of a small kinetic impactor spacecraft to mitigate an Earth-threatening asteroid is assessed by means of a novel measure of efficiency. This measure estimates the…

Optimization of Interplanetary Trajectories for Impulsive and Continuous Asteroid Deflection

It is found that several optimal interplanetary trajectories exist that allow a 750-Kg spacecraft to be launched from 2015-2026, and impact 99942 Apophis allowing prekeyhole deflections of orders of magnitude larger than the likely required amount.
