The Extreme ultraviolet imaging spectrometer is an important instrument for data acquisition in space science research. According to the observed radiance intensity of different celestial bodies＇ Extreme and Far ultraviolet radiation, main material＇s content and variations of celestial bodies can be calculated. It can provide research data for many frontier sciences such as the forecast of space weather and the research of cosmic o- rigin. The advantages of Extreme and Far ultraviolet imaging spectrometer in space science are analyzed and its developments abroad are introduced. The features of representative Extreme and Far ultraviolet explorers are presented by three applications covering solar-terrestrial environment observation, extraterrestrial planetary body＇s obse＇rvation and cosmic astral bodies observation. The key technologies of Extreme and Far ultraviolet imaging spectrometer are analyzed. A prospect of the developments of Extreme and Far ultraviolet space remote sensors is put forward to provide some kinds of helpful information for relative researches.
