Complex plasmas are composed of ionized gas and microparticles. As plasma state of soft matter, they play an important role in the fundamental physics and applications. Complex plasma research has always been an important research topic on board the space stations. The basic properties of complex plasmas are introduced, focusing on the charging mechanism and particle interactions. Four generations of microgravity facilities on the Mir Station and International Space Station with dc and rf discharges are described with six representative research topics, including charge induced coagulation, three−dimensional crystallization and melting, phase separation in binary complex plasma, electrorheology and string formation, dust acoustic wave driven by discharge polarity reversal and frequency synchronization, and vortex formed by particle flow. Related ground experiments are compared. An introduction to the design and functions of the future complex facilities on the International Space Station and Chinese Space Station are given.
