It carried 14 experiments prepared by seven countries in all, with participation from scientists in France, Czechoslovakia, Hungary, Poland, Romania, United States and the Soviet Union.

It included a centrifuge with revolving and fixed sections in which identical groups of animals, plants, and cells could be compared.

The effects of aging on fruit fly livers and plant tissues with grafted cancerous growths were also studied.

More than 20 different species were flown on the mission, including 25 unrestrained male Wistar rats, fruit flies (Drosophila melanogaster), carrot tissues, and 1,000 embryos of the fish Fundulus heteroclitus (a small shallow-water minnow).

A United States radiation dosimeter experiment was also carried out without using biological materials.
