Test three-dimensional attitude control system for future remote sensing; currently used for ice observation in Arctic.
Originally two scientific disciplines on a single spacecraft in studies of star formation/early solar system (astronomy) and of the mechanisms behind the depletion of the ozone layer in the earth atmosphere and the effects of global warming (aeronomy); astronomy mission has ended.
"First a technology demonstration, then extended for one year for remote sensing; looks like a washing machine."
