Frequently Asked Questions (1)
Q1. What are the contributions in "Design 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. The paper presents the design of the formation orbits and the multi-objective optimisation of the formation in order to minimise the total mass in space and maximise the deflection of the asteroid. The paper demonstrates how significant deflections can be obtained with relatively small sized, easy-to-control spacecraft.
