The vacuum ultraviolet（VUV） imaging spectrometer is an important instrument for data acquisition in the space science research. According to the observation to the radiance intensity of different celestial bodies＇ VUV radiation, main material＇s content and changes 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 origin. The advantages of VUV imaging spectrometer in space science are analyzed and its developments abroad are introduced. The features of representative VUV explorers are presented by three applications covering solar-terrestrial environment observation, extraterrestrial planetary body＇s observation and cosmic astral bodies observation. The key technologies of VUV imaging spectrometer are analyzed. A prospect of the developments of VUV space remote sensors is made to provide some kind of helpful information for relative researches.
