De-orbiting Model for Cleaning Irregularly Shaped Space Debris with Laser Radiation

摘要

The growing population of space debris in the size range of 1 to 10cm around the Earth has been posing a tremendous threat to space missions and assets. The proposal of using a ground-based laser has been viewed as the most feasible method to clean them. In previous work, shapes of debris objects were always assumed to be slabs; however, most of them were irregular. In this study we calculated the impulse of spheres, cylinders and cones by laser radiation. Then, a de-orbiting model was constructed. Simulation results indicated that fragments of a sphere could re-entry atmosphere during a single pass over the ground-based laser while fragment of a cone and a cylinder couldn't in our assumed de-orbiting conditions.
