Solar Sail Far-Range Rendezvous Operations For Active Debris Removal

Abstract

The escalating problem of space debris necessitates effective solutions, such as active debris removal, to ensure sustainable orbital environments. Solar sails, with their nearly unlimited ΔV budget, present a promising, propellant-free method for targeting and potentially removing debris. However, the unique dynamics of solar sails prevent them from maintaining fixed positions relative to a target. This research explores the use of hold trajectories as alternatives to static hold points during far-range rendezvous operations. Using InTrance, a trajectory optimisation tool based on neuroevolution, the study assesses how operational constraints impact hold trajectories and the viability of preliminary homing trajectories. Results indicate that hold trajectories allow safe, extended solar sail operations close to debris, supporting sustained observation and monitoring efforts for debris management.
