Status: Study 1992. Gross mass: 21,000 kg (46,000 lb). Height: 12.00 m (39.00 ft).
Named the Bioteknologiya Space Vehicle, this proposed materials science spacecraft had a launch mass of 21 metric tons of which 8-9 metric tons represent the payload.
The maximum diameter was 4.3 m and the length was approximately 12 m. Two solar arrays generate up to 3 kW average power and 10 kW for peak loads. Microgravity conditions of 10^-4 g were possible for year-long missions at altitudes of 350-450 km. A unique aspect of the Bioteknologiya Space Vehicle was its ability to return materials in small recoverable modules periodically throughout the mission. Ballistic capsules (5 or more) with a capacity of 120 kg and a volume of 120 liters were loaded separately, then ejected from the main spacecraft for the return to Earth. Since the basic spacecraft systems had already been developed and tested in space, the preparation period for this specialized vehicle was given as only 2-3 years.
