Sommario:
- <p>A method is disclosed for active orbital debris removal in which two satellites operate in coordinated<br>formation on opposite sides of a target debris object and direct continuous-wave or pulsed laser<br>ablation beams onto opposing faces of the target. The bilateral geometry provides three simultaneous<br>effects: (1) surface ablation gradually weakens the structural integrity of degraded fasteners, adhesives,<br>and thermal blankets on the debris exterior; (2) symmetric ablation plumes produce opposing<br>reaction-torque components that cancel each other, suppressing the spin-up that would otherwise<br>destabilize a single-beam ablation push; and (3) the combined photon pressure and plume-thrust<br>components add as decelerating impulse, producing a retrograde Δv that lowers perigee until<br>atmospheric drag completes reentry. A reinforcement-learning–trained formation-flying controller<br>coordinates relative position, beam pointing, and pulse phasing in real time across both satellites, using<br>cooperative LiDAR and optical tracking of the non-cooperative target. The disclosure does not claim<br>disintegration of the target; on the contrary, it explicitly avoids the threshold fluence that would<br>fragment the object. The novelty resides in the paired-satellite torque-cancelled ablation geometry<br>combined with an AI-coordinated formation-flying control loop. No claim is made to the underlying<br>laser-ablation physics, plasma-plume mechanics, or formation-flying mathematics, all of which are<br>established art.</p>
