Abstract
Recent and scheduled chemical analysis in space missions are reviewed. Recent progress in analytical chemistry have made it possible to analyze chemical cpmposition of extraterrestrial samples in space. VEGA-1 and Giotto utilized mass spectrometers to analyze cometary dust particles. Phobos I and II are flying toward Mars and its moons. They carry various instruments to analyze Martian atmosphere and surface material of Phobos. NASA is planning to launch unmanned spacecrafts with mass spectrometers on board to comets and Jupiter. Various kinds of organic compounds were/are being detected in extraterrestrial matters. These facts promote the study of chemical evolution toward origins of life in space.
