In aeronomy, ODIN will study the atmosphere, particularly in regard to the formation and deterioration of ozone and how it affects the ozone hole. With more knowledge, we get closer to the answers to important questions like how pollution affects the atmosphere.

in astronomy, the satellite will also be spreading new light over the chemical processes that control the chain of events involved in the formation of new stars. ODIN will also be studying comets which are by-products of new star formation, and can give new clues as to how our own solar system was formed.
