AKA: Aureole;Oreol. Status: Operational 1971. First Launch: 1971-12-27. Last Launch: 1973-12-26. Number: 2 . Gross mass: 590 kg (1,300 lb).

This was a Soviet-French collaborative project, Russian code name Arkad. Launched by Kosmos-2, the spacecraft studied physics and the characteristics of the upper atmosphere. Instruments included Soviet/French magnetosphere and ionosphere experiments, equipment for studying the physical processes in the earth's magnetosphere and ionosphere, and study of the nature of polar aurora.
