Bion programme Kosmos (satellites) | |
Kosmos 936 or Bion 4 (Бион 4, Космос 936) was a Bion satellite.[4] The mission involved nine countries in a series of biomedical research experiments. The experiments were primarily follow-ups to the Bion 3 (Kosmos 782) flight. Scientists from the Bulgaria, Czechoslovakia, East Germany, France, Hungary, Poland, Romania, the United States and the Soviet Union conducted experiments in physics and biology on the mission.[1]
