List of Buran missions

The Buran programme was an attempt by the Soviet Union to construct an orbital spaceplane to perform similar functions to the Space Shuttle. Similar to the Space Shuttle programme, an aerodynamic prototype and a number of operational spacecraft were planned for the Buran programme,^[1] which were known as "Buran-class orbiters".

The aerodynamic testbed OK-GLI was constructed in 1984 to test the in-flight properties of the Buran design. Unlike the American prototype Enterprise, OK-GLI had four AL-31 turbofan engines fitted, meaning it was able to fly under its own power.^[2]

The list does not include taxi tests without takeoffs. All of these missions were landed at the Gromov Flight Research Institute test base.

The first operational orbiter, Buran flew one test mission, designated 1K1, on November 15, 1988 at 6:00:00 Moscow time.^[6] The spacecraft was launched uncrewed from and landed at Baikonur Cosmodrome in the Kazakh S.S.R. and flew two orbits, traveling 83,707 km (52,013 mi) in 3 hours, 25 minutes (0.14 flight days).^[7] Buran never flew again; the program was cancelled shortly after the dissolution of the Soviet Union.^[8] In 2002, the collapse of the hangar in which it was stored destroyed the Buran orbiter.^[9][10]

Due to shortening of the program and delays in second flight preparations, mission plan for second orbiter included almost all significant test tasks.

• automatic docking with Mir's Kristall module
• crew transfer from Mir to the shuttle, with testing of some of its systems in the course of twenty-four hours, including the remote manipulator
• undocking and autonomous flight in orbit
• docking of the crewed Soyuz-TM №101 with the shuttle
• crew transfer from the Soyuz to the shuttle and onboard work over the course of twenty-four hours
• automatic undocking and landing
