The Buran spacecraft (Russian: Бура́н, IPA: [bʊˈran], Snowstorm or Blizzard), GRAU index 11F35 K1 is a Russian (Soviet) orbital vehicle (in Russian terminology: "орбитальный самолет", - "orbital airplane") analogous in function to the U.S. Space Shuttle and developed by Chief Designer Gleb Lozino-Lozinsky of Energia rocket corporation. To this day Buran remains the only space shuttle vehicle from the Soviet Buran program that was launched in space before the program closure. The Buran completed one unmanned spaceflight in 1988 before the cancellation of the program in 1993 and was later stored in a hangar at Baykonur cosmodrome before a hangar collapse accident in 2002 destroyed both the hangar and the orbital vehicle. ^[2]

Flight into space
The only orbital launch of Buran occurred at 3:00 UTC on 15 November 1988 from Baikonur Cosmodrome Site 110/37. It was lifted into orbit unmanned by the specially designed Energia rocket, which to this day remains the heaviest rocket running on liquid fuel. Unlike the Space Shuttle, which is propelled by a combination of solid boosters and the Shuttle's own liquid-fuel engines sourcing fuel from a large fuel tank, the Energia-Buran system used only thrust from the rocket's four RD liquid-fuel engines developed by Valentin Glushko. From the very beginning Buran was intended to be used in both fully automatic and manual mode. Although the program accumulated a several-years delay, to this day Buran remains the only space shuttle to ever perform an unmanned flight in fully automatic mode. The automated launch sequence performed as specified, and the Energia rocket lifted the vehicle into a temporary orbit before the orbiter separated as programmed. After boosting itself to a higher orbit and completing two revolutions around the Earth, ODU (engine control system) engines fired automatically to begin the descent into the atmosphere. Exactly 206 minutes into the mission, the Buran orbiter landed, having lost only five of its 38,000 thermal tiles over the course of the flight.[4] The automated landing took place on a runway at Baikonur Cosmodrome where, despite a lateral wind speed of 61.2 kilometres per hour (38.0 mph), it landed only 3 metres (9.8 ft) laterally and 10 metres (33 ft) longitudinally from the target mark.[4] The unmanned flight was the first time that a spacecraft of this size and complexity had been launched, completed maneuvers in orbit, re-entered the atmosphere, and landed under automatic guidance.-
