The Soviet reusable spacecraft program Buran (meaning "Snowstorm" or "Blizzard" in Russian) began in 1974 at TsAGI as a response to the United States Space Shuttle program. The project was the largest and the most expensive in the history of Soviet space exploration. The idea saw its first iteration in the Burya high-altitude jet aircraft, which reached the prototype stage. Several test flights are known, before it was cancelled by order of the Central Committee. The Burya had the goal of delivering a nuclear payload, presumably to the United States, and then returning to base. The cancellation was based on a final decision to develop ICBMs. The next iteration of the idea was Zvezda from the early 1960s, which also reached a prototype stage. Decades later, another project with the same name was used as a service module for the International Space Station. After Zvezda, there was a hiatus in reusable projects until Buran. The construction of the shuttles began in 1980, and by 1984 the first full-scale Buran was rolled out. The first suborbital test flight of a scale-model (BOR-5) took place as early as July 1983. As the project progressed, five additional scale-model flights were performed. The only orbital launch of the (unmanned) Buran shuttle 1.01 was at 3:00 UTC on 15 November 1988. It was lifted into orbit by the specially designed Energia booster rocket. The life support system was not installed and no software was installed on the CRT displays. The shuttle orbited the Earth twice in 206 minutes of flight. On its return, it performed an automated landing on the shuttle runway at Baikonur Cosmodrome. After the first flight, the project was suspended due to lack of funds and the political situation in the Soviet Union. The two subsequent orbiters, which were due in 1990 and 1992 were never completed. The project was officially terminated on June 30, 1993 by President Boris Yeltsin. At the time of its cancellation, 20 billion roubles had been spent on the Buran program. The program was designed to boost national pride, carry out research, and meet technological objectives similar to those of the U.S. shuttle program, including resupply of the Mir space station, which was launched in 1986 and remained in service until 2001. When Mir was finally visited by a space shuttle, the visitor was a U.S. shuttle, not Buran. The Buran completed only one unmanned spaceflight in 1988 before its cancellation in 1993. The Buran spacecraft was destroyed in the Buran hangar collapse on May 12, 2002. [READ THE REST OF THIS ARTICLE]
