Russian manned lunar lander. Study 1988. Lunar lander 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 (5 days standard, 10 with additional consumables) on the surface, the ascent stage of the LK would return to lunar orbit, and the crew would transfer back to the LOK. Prior to landing an unmanned Lunokhod would scout the region, allowing selection of a suitable landing site, and serve as a landing beacon for the precision LK landing.

Crew Size: 3. Orbital Storage: 30 days.

AKA: Lunniy korabl.
Gross mass: 29,000 kg (63,000 lb).
Height: 9.80 m (32.10 ft).
Span: 8.40 m (27.50 ft).

  • Lunar Landers Lunar lander design started with the British Interplanetary Society's concept of 1939, followed by Von Braun's 3964 tonne monster of 1953. It then settled down to more reasonably-sized variants. Landers came in three main types: two stage versions, with the first stage being a lunar crasher that would brake the spacecraft until just above the lunar surface, then separate, allowing the second stage to land on the surface; two stage versions consisting of a descent stage that went all the way to the surface, and an ascent stage that would take the crew from the surface to lunar orbit or on an earth-return trajectory; and single stage versions, using liquid oxygen/liquid hydrogen propellants.

  • 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...
