Optimal impact strategies for asteroid deflection
This paper presents an analysis of optimal impact strategies to deflect potentially dangerous asteroids. In order to compute the increase in the minimum orbit intersection distance of the asteroid due to an impact with a spacecraft, simple analytical formulae are derived from proximal motion equations. The proposed analytical formulation allows for an analysis of the optimal direction of the de...
متن کاملAsteroid Impact and Deflection Assessment mission
The Asteroid Impact and Deflection Assessment (AIDA) mission will be the first space experiment to demonstrate asteroid impact hazard mitigation by using a kinetic impactor to deflect an asteroid. AIDA is an international cooperation entering Phase A study at NASA and ESA, consisting of two mission elements: the NASA Double Asteroid Redirection Test (DART) mission and the ESA Asteroid Impact Mi...

متن کاملOptimization of Interplanetary Trajectories for Impulsive and Continuous Asteroid Deflection
The chaotic dynamic of near earth objects and our limited knowledge on the asteroid population makes it impossible to predict the next impact of an asteroidwith our planet. The collision at Jupiter of the comet Shoemaker– Levy 9, the more recent discovery of the asteroid 99442 Apophis, and other similar events, have stimulated the discussion on our capabilities of deflecting an asteroid in coll...
متن کاملDesign of a Formation of Solar Pumped Lasers for Asteroid Deflection
This paper presents the design of a multi-spacecraft system for the deflection of asteroids. Each spacecraft is equipped with a fibre laser and a solar concentrator. The laser induces the sublimation of a portion of the surface of the asteroid, and the resultant jet of gas and debris thrusts the asteroid off its natural course. The main idea is to have a formation of spacecraft flying in the pr...
