Technologiya
The second materials science spacecraft innovation being offered by the Salyut Design Bureau is called Technologiya and is based on a new spacecraft bus called the Unified Space Platform (USP). The USP is designed to handle payloads of up to 10 metric tons with stowed dimensions of 4.1 m diameter and 6.7 m length. The USP will supply electrical power up to 12 kW, attitude control with a precision of 10' to 1 degree, orbital maneuver capability, and other support functions. Mission durations of as long as five years are possible in orbits up to 500 km with inclinations of 51.6 degrees, 65 degrees, or 72 degrees. Launches would be provided by the Proton within 3-4 years of contract agreement (Reference 808).
Under the Technologiya program, the Salyut Design Bureau has already designed a customized microgravity payload unit for the USP. The 20 metric ton vehicle will be capable of carrying 4-5 metric tons of processing equipment for the manufacture of semiconductor materials, optical glasses, and biological preparations in a volume of up to 30 m3. A maximum mission duration of three years at a 400-450 km altitude is possible. Products and processing equipment will be returned to Earth in a large recoverable module (Reference 809).
