![]() The automated launch sequence performed as specified, and the Energia rocket lifted the vehicle into a temporary orbit before the orbiter separated as programmed. 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. From the very beginning Buran was intended to be used in both fully automatic and manual mode. 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. It was lifted into orbit unmanned by the specially designed Energia rocket, which to this day remains the heaviest rocket running on liquid fuel. The only orbital launch of Buran occurred at 3:00 UTC on 15 November 1988 from Baikonur Cosmodrome Site 110/37. 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. 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 spacecraft was launched uncrewed from and landed at Baikonur Cosmodrome in the Kazakh S.S.R. The first operational orbiter, Buran flew one test mission, designated 1K1, on Novemat 6:00:00 Moscow time.
