Abstract: To purify the space environment，the existing spacecraft de-orbit technologies were analyzed for the spacecraft de-orbit problem at the lifetime end.The research status of spacecraft end-of-life de-orbit technologies was introduced.The characteristics and applicability of various de-orbit methods were summarized.Then the development trends and key technologies of various de-orbit methods were analyzed，and the development suggestions for the de-orbit technologies at the lifetime end of the spacecraft were put forward.The results show that the spacecraft end-of-life de-orbit technologies can de-orbit spacecraft within 25 years，but the reliability of de-orbit device，the stability of deorbit，the deorbit time of spacecraft and the aftertreatment can still be greatly improved.
