Development of A Novel Micro Electric Propulsion System for Space Application

Abstract

Space debris poses significant challenges to orbital operations and satellite missions, necessitating urgent and innovative remediation strategies. This research underscores the potential of CubeSats in Active Debris Removal (ADR) efforts. An ontology-based feasibility assessment is developed for the three main ADR mission phases. An assessment of various capture strategies—including robotic arms, clamps, and notably, tentacles—was conducted. Tentacles, with their inherent adaptability, emerged as strong candidates for ADR missions targeting high-priority debris. State-of-the-art miniaturized electric propulsion systems demonstrated proficiency in performing the circular fly-around and deorbiting maneuvers on 70% and 40% of the high-priority debris database, respectively. A novel approach was introduced through the Laser Ablation Propulsion Thruster (LAPT) embedded within CubeSat, which employs debris as propellant. This addresses the dual challenge of debris mitigation and limited onboard fuel. Evaluations were conducted on the material composition of space debris to derive optimal laser parameters for ablation. Trials on CubeSats confirmed their potential, with a specific laser system identified as optimal in terms of power and efficiency. The findings of this research pave the way for effective space debris management strategies but also shed light on the potential of CubeSats in broader space missions.
