Abstract:  Spacecraft reconfiguration technology is the key technology that must be broken through for the in-orbit service of spacecraft and other major space missions，having a profound effect on the design，research and development of new spacecraft systems.Firstly，the connotation and classification of the spacecraft reconfiguration were presented.Then，the domestic and overseas research status of the technology was systematically concluded and discussed based on main structure reconfiguration and other typical technologies.Next，the system of the spacecraft reconfiguration technology was proposed based on the methods such as standardized modular design，and then application prospects were summarized in the aspects such as supporting fault elimination of spacecraft.Finally，overall research progress of the reconfiguration technology was concluded，and future development was also expected.

Key words: spacecraft reconfiguration, in-orbit service, main structure reconfiguration, standardized modular design, spacecraft fault elimination
