Ralph Mirebs, an urban explorer and photographer in Russia, has revealed extraordinary photos of Soviet space shuttle prototypes gathering dust in an abandoned hangar. The abandoned hangar is located at the Baikonur Cosmodrome in Kazakhstan, which is still in operation today (with the close of NASA’s shuttle program, Russian Soyuz shuttles are the only way for astronauts to reach the International Space Station). The Buran prototype shuttles found by Mirebs, however, are from an earlier era – they are the last remnants of a space program that began in 1974 and was finally shuttered in 1993.
