TITLE Energy Variation of Space Debris Considering Orbital Maneuvers and Ground-based Laser |
 PDF |
ABSTRACT The frequency of space debris incidents is on the rise, particularly in regions where there are critical densities, elevating the risk of collisions. Ground-based lasers, when precisely targeted, have the potential to induce propulsion effects that can alter the perigee of debris particles. This alteration facilitates their swift incineration upon reentry into Earth’s atmosphere or enables adjustments to their orbital trajectories. The objective was to assess the effectiveness of orbital maneuvers, considering gravitational influences alongside the utilization of ground-based lasers. We focused on space debris ranging from 1 cm to 10 cm in size, orbiting at altitudes between 100 and 1000 km, as they approach Earth within a hypothetical heliocentric orbit. Through our analyses, we examined variations of velocity and energy following close approaches, employing singlepulse laser propulsion. This investigation is crucial for evaluating the orbital characteristics of space debris, contributing to safe reentry into Earth’s atmosphere and collision avoidance through precise impulse application by ground-based lasers. Our analytical model factors in laser fluence, debris attitude, and the relative motion between the laser and debris. Our results indicate that the laser induces minor changes in delta-V, with maximum energy efficiency that can be harnessed to enhance reentry energy. Consequently, it is possible to achieve a 30%increase in the variation of orbital elements after the maneuver. This study thus offers a comprehensive examination of such maneuvers, highlighting their advantages over traditional orbital adjustments and outlining optimal conditions for collision avoidance and space debris mitigation. We recommend further enhancing dynamic modeling and validating experimental outcomes to refine our understanding of these studies. |
