- Abstract
In order to reduce the generation of space debris effectively, avoid the space debris endanger the safety of space activities and spacecrafts, protect the space environment, it becomes a necessary and urgent issue that the launch vehicle last stage de-orbits passively or using its own power after the payload separation. In this paper, the passively and actively de-orbit technologies and their development trends of domestic and international launch vehicle last stage are elaborated. Several actively de-orbit options of the near-orbit launch vehicle last stage which use its own power are focused on. And the relative key technologies of actively de-orbit are discussed in detail, which includes the orbit design methods, the flight procedure design, the propellant management technology and the attitude control technology, etc. Finally a feasible scheme is proposed, which solved the problem that control the orbital lifetime of the near-orbit launch vehicle last stage less than 25 years. This scheme lays a foundation to the realization for the orbital lifetime control of the launch vehicle last stage and the mitigation for space debris.
