Russian manned lunar orbiter. Study 1988. Lunar orbiter for Energia-launched lunar expedition. The LOK and LK lander would be inserted into lunar orbit by separate Energia launches.

After rendezvous and docking in lunar orbit, three of the five crew aboard the LOK would transfer to the LK and descend to the lunar surface. After 5 to 10 days on the surface, the ascent stage of the LK would return to lunar orbit, and the crew would transfer back to the LOK. The LOK would remain in lunar orbit for a full lunar day (29 days) until returning to earth.

Crew Size: 5. Orbital Storage: 30 days.

AKA: Lunniy orbital'niy korabl'.
Gross mass: 30,000 kg (66,000 lb).
Height: 9.60 m (31.40 ft).

  • Lunar Orbiters Manned lunar orbiters and orbiting stations were rarely designed for this purpose alone, but usually used in a lunar-orbit rendezvous lunar landing scenario together with a separate lunar lander. They were more powerful than circumlunar manned spacecraft in that they required substantial propellant to brake into and get out of lunar orbit. More...
  • 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
  • Energia The Energia-Buran Reusable Space System (MKS) began development in 1976 as a Soviet booster that would exceed the capabilities of the US shuttle system. Following extended development, Energia made two successful flights in 1987-1988. But the Soviet Union was crumbling, and the ambitious plans to build an orbiting defense shield, to renew the ozone layer, dispose of nuclear waste, illuminate polar cities, colonize the moon and Mars, were not to be. Funding dried up and the Energia-Buran program completely disappeared from the government's budget after 1993. More...
