an international astronomy and aeronomy mission led by Sweden, with
Canada, France, and Finland as partners. Canada has a 20% share in
both aspects of the mission, with funding provided by
The Canadian Space Agency
The Natural Science and
Engineering Research Council.
Dr. Kwok is the Principal Investigator for
Astronomy in Canada.
Odin was launched from Svobodny, Siberia on February 20, 2001.
The duration of the mission was expected to be 2
years, but Odin is still observing in 2005.
bands are accessible, centred on 495, 548, 555 and 571 GHz. The
radiometer provides a 17 GHz tuning range about each of these
frequencies and has an instantaneous bandwidth of 1 GHz. There is also
a fifth band in the millimetre range centred on 119 GHz. The
spatial resolution is ~2 arcmin at sub-millimetre wavelengths and ~9
arc min at 119 GHz. Many molecular and atomic lines of astronomical
interest are accessible for the first time. A major goal is to study
the interstellar and circumstellar oxygen chemistry using water and
oxygen molecules. These species are key to the oxygen budget but
neither is detectable from the ground. Odin observations have an
impact on a wide range of subjects including molecular cloud
chemistry, shock chemistry, star-forming cores, circumstellar
envelopes, interstellar clouds, photodissociation regions, comets,
planetary atmospheres, and extragalactic molecules. The University of
Calgary participated in the building of the submm receiver
payload, in software simulations and is active in data processing and
