Verny vs Bion

Verny was a rhesus macaque carried aboard the Soviet biosatellite Bion 7, also designated Kosmos 1667. The spacecraft remained in orbit from July 10 to July 17, 1985, conducting biomedical research into the effects of spaceflight on living organisms. Verny was one of the primates used by the Bion program to collect physiological data relevant to human spaceflight and adaptation to microgravity.

Bion was a Soviet rhesus macaque who flew aboard the Kosmos 1514 satellite as part of the Bion 6 mission in 1983. Alongside another macaque named Abrek, Bion was launched into space to study physiological changes during spaceflight. The mission marked the beginning of the Soviet Union's Bion satellite primate program, aiming to understand how complex organisms might react to prolonged periods in m...
