Odin is a Swedish-led submillimeter wave spectroscopy satellite for astronomy and atmospheric research, supported by scientists and space agencies in Canada, Finland, France, and Sweden (>51 %). The satellite is equipped with a 1.1 m antenna, four tunable submillimeter wave mixer receivers, a fixed-tuned receiver at 119 GHz dedicated to deep searches for molecular oxygen, O2, and an optical/near-infrared receiver for aeronomy purposes. Odin was launched from far eastern Russia on 20 February 2001 and still is in full operation in 2013. The central aeronomy program consists of global, long-term temporal monitoring of the distributions of ozone and connected species such as ClO. The astronomy program was mainly dedicated to observations H2O, NH3, and O2 in comets, planetary atmospheres, star formation regions, and circumstellar envelopes around late-type stars. Odin and NASA’s SWAS(launched 2 years earlier) have both provided important pilot studies for the larger and much...
