Encyclopedia Astronautica

Variant of the Energia launch vehicle with two strap-on boosters instead of four. This would have fullfilled the 50 tonne payload requirement had the third generation booster plan been fully implemented.

LEO Payload: 50,000 kg (110,000 lb) to a 200 km orbit at 51.60 degrees.

  • 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...
