ODIN is a Swedish satellite working in two disciplines; astrophysics and aeronomy, and it was named after god Odin. Within the field of astrophysics, Odin is used in the study of star formation. When used for aeronomical observations, it is the ozone layer depletion and effects of global warming that are explored.
Odin was developed by the Space Systems Division of Swedish Space Corporation (now OHB Sweden) as part of an international project involving the space agencies of Finland (funded by TEKES), Canada (CSA) and France (CNES).
Odin was launched on a START-1 rocket on February 20, 2001 from Svobodny, Russia on February 20, 2001. The duration of the mission was expected to be 2 years, but Odin is still observing (July 2012).
The onboard instrument measuring the ozone depletion is named OSIRIS.
