ODIN is a submm/mm space telescope (1.1 m aperture, 2' and 9' beam at 557 GHz 119 GHz, respectively,) launched from eastern Russia in February 2001.

Observations have been made towards Sgr A (the CircumNuclear Disk, the +20 and +50 kms-1 molecular clouds) and Sgr B2 in the Galactic Centre and we report here on the results of searches for H2O, H218O and O2 in these regions.

ODIN is a Swedish-led satellite project funded jointly by the Swedish National Space Board (SNSB), the Canadian Space Agency (CSA), the National Technology Agency of Finland (Tekes) and the Centre National d'Etudes Spatiales (CNES, France). The Swedish Space Corporation was the prime contractor for development and launch of ODIN and is responsible for the operation of the satellite
