The Energia (or Energiya, Энергия in Russian, meaning Energy) rocket was a Soviet rocket that was designed by NPO Energia to serve as a heavy-lift expendable launch system as well as a booster for the Buran Space Shuttle. It had the capacity to place around 100 metric tons in Low Earth orbit.
Work on the Energia/Buran system began in 1976 after the decision was made to cancel the unsuccessful N1 rocket. The cancelled N1 rocket-based Manned Lunar Launch Facilities and Infrastructure were used for Energia (notably the huge horizontal assembly building) - just as NASA reused infrastructure designed for the Saturn V in the Space Shuttle program. Energia also replaced the "Vulkan" concept, which was a design based on the Proton rocket and using the same toxic hypergolic fuels, but much larger and more powerful. The "Vulkan" designation was later on given to a variation of the Energia which has eight boosters and multiple stages.
The Energia was first test-launched 15 May 1987 21:30 with Polyus (UKSS military payload), where the Energia itself functioned well, but the Polyus did not reach orbit due to a mishap of its own attitude control system after separation from Energia.

Featured biography
Robert Hutchings Goddard (October 5, 1882 – August 10, 1945), U.S. professor and scientist, was a pioneer of controlled, liquid-fueled rocketry. He launched the world's first liquid-fueled rocket on March 16, 1926. From 1930 to 1935 he launched rockets that attained speeds of up to 550 miles an hour. Though his work in the field was revolutionary, he was often ridiculed for his theories. He received little recognition during his own lifetime, but would eventually come to be called one of the "fathers of modern rocketry" for his life's work.
