CHAMP (Challenging Mini-Satellite Payload) is a German small satellite mission for geoscientific and atmospheric research and applications, managed by GFZ. MITA carries the payload NINA-2 for the study of solar and galactic cosmic rays. The detector used in this mission is identical to the one already flying on the Russian satellite Resurs-O1 4 in a 840 km sunsynchronous orbit, but makes use of the extensive computer and telemetry capabilities of MITA bus to improve the active data acquisition time.
