Recently, the public has focused on the safety and reliability of complex equipment such as aerospace. Health management about complex equipment contains state detection, fault prognostics, fault diagnosis and so on, and is the guarantee for accomplishment of space missions and the long-term operation of in-orbit spacecraft. Under the background, the development of prognostics and health management (PHM) technology, aiming at improving equipment safety and reliability, which can eliminate faults in the embryonic state, has a profound significance for condition monitoring and in-orbit maintenance of aerospace equipment. By analyzing the research status and application of PHM technology both at home and abroad, the manuscript majorly addressed the PHM technical framework and key technologies about spacecraft. In the meanwhile, integrated with cloud service platform for equipment management, the development tendency of PHM was forecast. At last, the existing challenges of PHM technology was expounded and corresponding countermeasures were put forward.
