Ptichka

Ptichka (Russian: Пти́чка, IPA: [ˈptʲitɕkə], Little Bird) is an informal nickname for the second space shuttle orbiter to be produced as part of the Soviet/Russian Buran program. It carried the GRAU index serial number 11F35 K2 and is - depending on the source - also known as "OK-1K2", "Orbiter K2", "OK 1.02" or "Shuttle 1.02". This Buran-class shuttle orbiter was never officially named. Ptichka was an informal nickname for all of the Buran-class orbiters.

OK-1K2 is distinguishable from the other Buran-class orbiters by a red framework attached to the top of its cargo bay doors.

Construction

Construction of the second orbiter started in 1988, and although OK-1K2 was closest to being completed of any of the Buran-class orbiters (after the OK-1K1 orbiter), it was never finished. The program was officially canceled in 1993, at which point the shuttle was 95-97% complete.

Projected flights

Projected flights^[2] as of 1989:

• 1991 — unmanned first flight, with a duration of 1–2 days.
• 1992 — unmanned second flight, with a duration of 7–8 days. Orbital maneuvers and space station approach test.

Changed in 1991:

• December 1991 — unmanned second flight, with a duration of 7–8 days. Orbital maneuvers and space station approach test:
  • 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 manned Soyuz-TM 101 with the shuttle
  • crew transfer from the Soyuz to the shuttle and on board work in the course of twenty-four hours
  • automatic undocking and landing

Status

OK-1K2 is currently the property of Kazakhstan-Russia Joint Venture Company Aelita, a subsidiary of RKK Energia, and is stored in the MZK building at Baikonur Cosmodrome.^[1] Location: 45°56′25.6″N 63°19′6.3″E / 45.940444°N 63.318417°E / 45.940444; 63.318417.
