Russian manned spacecraft. Cancelled 1989.' Super Soyuz' replacement for Soyuz and Progress.

Concept was reusable spacecraft, launched by Zenit launch vehicle, with all possible systems recovered in landing module, together with significant payload delivered to and returned from orbit. Carriage in payload bay of Buran shuttle was also a requirement. Preliminary design work began on 27 January 1985. The design was briefed to the Military-Industrial Commission on 22 December 1986. However the project was cancelled in January 1989 on financial grounds.

Zarya would have been used for four missions:

  • Launched into a 190 km, 51.6 degree orbit for docking with Mir-type space stations. In this role it would have carried two to four crew plus around two metric tons of payload up to 300-550 km orbits and back to earth.
  • Rescue or lifeboat configuration, with 1,2, or no crew, returning up to 12 cosmonauts to earth (4 on first floor and 8 on second floor of capsule).
  • With a crew of 2-3, for construction or repair of spacecraft in low earth orbit;
  • In unpiloted form, as a spacecraft for resupply or refueling of spacecraft in high orbits up to 36,000 km (geosynchronous) altitude.

The capsule was 3.7 m in diameter, and had a total mass of 13 metric tons. When flown manned, 5-6 crew and 1,500 kg of cargo could be carried. If unmanned, a maximum cargo of 3,750 kg could be carried. An androgynous docking system was mounted at the front of the spacecraft, as were the antennae of the radio systems. A small engine module was mounted at the rear for orbital maneuver and retrofire. It was jettisoned before re-entry and was the only expendable part of the spacecraft.

After re-entry, a stabilization parachute was ejected. This was equipped with a radio altimeter in the parachute lines. Just before impact with the ground the altimeter triggered a large array of rocket engines arranged in a circle around the body of the re-entry vehicle. These braked the capsule to a soft landing. The braking and orientation engines were liquid propellant but used non-toxic propellants since they were housed within the capsule.

The design had several defects, chiefly the severe acoustic environment inflicted on the crew in the braking maneuver and the lack of any back-up landing system in the event of failure of the braking rockets to ignite.

  • Soyuz The Russian Soyuz spacecraft has been the longest-lived, most adaptable, and most successful manned spacecraft design. In production for fifty years, more than 240 have been built and flown on a wide range of missions. The design will remain in use with the international space station well into the 21st century, providing the only manned access to the station after the retirement of the shuttle in 2011. More...

Associated Launch Vehicles
  • Zenit Zenit was to be a modular new generation medium Soviet launch vehicle, replacing the various ICBM-derived launch vehicles in use since the 1960's (Tsiklon and Soyuz). A version of the first stage was used as strap-ons for the cancelled Energia heavy booster. But it was built by Yuzhnoye in the Ukraine; when the Soviet Union broke up planned large-scale production for the Soviet military was abandoned (Angara development was begun as an indigenous alternative). Launch pads were completed only at Baikonur; those at Plesetsk were never finished and are planned to be completed as Angara pads. However the vehicle found new life as a commercial launch vehicle, launched from a sea platform by an American/Ukrainian consortium. More...
