摘要

SPACE debris, which includes discarded rocket stages, broken satellites, and other uncontrolled unmanned objects, has become a great threat to space activities. Studies indicate that the number of debris objects in low Earth orbit (LEO) will continue to increase, even if no new spacecraft are launched, as a consequence of collision between existing debris, This situation, known as Kessler's syndrome, has been predicted by Kessler et al. using a space debris environment model, Nonetheless, launch activities are still ongoing, and some unpredicted events have increased the debris population more than expected, such as the destruction of Fengyun-1C in 2007 and the collision between Iridium-33 and Cosmos-2251 in 2009. These events created a serious hazard for the Earth orbital environment. Active debris removal (ADR) is an effective means for stabilizing the orbital environment, Many ADR methods have been studied and proposed, including chemical and electric thruster deorbit kits, drag augmentation, solar radiation force, momentum transfer, electrodynamic tethers, and the debris engine. ADR is very costly; therefore, it is not affordable or practical to remove only one piece of debris per launch. In addition, every launch may create more debris. Multidebris removal per single launch is more effective and economical.
