Mission

Eighty experiments were conducted in such categories as motion sickness, reproduction and regeneration, immunology, and readaption to a normal gravity environment. A number of different biological specimens were used, including rodents.

The joint U.S./U.S.S.R. experiments were conducted on 2 rhesus monkeys and 10 male Wistar rats. The biological payload also included cell cultures (Escherichia coli). The prime occupants were two macaque monkeys. The 2.3 m diameter descent sphere was successfully recovered after 14 days, but a failure in the thermal control system resulted in the deaths of some of the specimens.
