Optimal Interplanetary Trajectories for Impulsive Deflection of Potentially Hazardous Asteroids under Velocity Increment Uncertainties

Abstract: This paper investigates the interplanetary trajectories associated with the impulsive deflection of a potentially hazardous asteroid (PHA) considering the uncertainty of the velocity increment that a spacecraft gives to the PHA at the collision. The velocity increment is assumed to have uncertainties of magnitude and direction due to estimation errors of asteroid shape and mass distributions. The uncertainty is modeled using a convex model assuming that magnitude and direction vary independently. The effect of… Show more
