Odin.

About Odin

Odin was a Swedish satellite working in two disciplines: astrophysics and aeronomy. It was named after Odin of Norse mythology. Within the field of astrophysics, Odin was used until the spring of 2007 aiding in the study of star formation. Odin was used for aeronomical observations, including exploration of the depletion of the ozone layer and effects of global warming. The satellite was functioning nominally until it deorbited on 3 August 2026.
