Soviet Space Shuttle Buran

The 2nd of two patches worn by Cosmonauts in the Soviet Union's space shuttle program from 1988 to 1991.  This patch is very rare!
The Soviet Space Shuttle "Buran"  (which means snowstorm) was larger, more advanced, and could carry more payload than it's American counterpart.  This beautifully embroidered shirt shows the Buran and "Energia"  (which means energy) rocket booster on a waving USSR flag.



Buran Soviet Space Shuttle

History

The Russian Shuttle Buran ("Snowstorm" in Russian) was authorized in 1976 in response to the United States Space Shuttle program. Building of the shuttles began in 1980, with the first full-scale Aero-Buran rolling out in 1984. It was launched by Energia LV.

Test Flights

The first suborbital test flight of a scale model of Buran took place in July 1983. There were five additional flights of the scale model in following years. Aerodynamic tests of the full-scale Buran analogue began in 1984. This aero-Buran was worn out after 24 test flights and would not fly again. The last of these aerodynamic test flights was in April 1988.
Orbital Launch

The first and only orbital launch of the shuttle Buran was at 3:00 GMT on November 15, 1988. The flight was unmanned, as the life support system had not been checked out and the CRT displays had no software installed. The vehicle was launched on the powerful Energiya booster into an 247 by 256 km orbit at 51.6 degrees inclination. The Buran orbited the Earth twice before firing its thrusters for reentry. The flight ended at 6:25 GMT when the vehicle touched down at Tyuratum. The Buran 1 mission was limited to 2 orbits due to computer memory limitations.

Aftermath

Although the first orbital flight of Buran was unmanned, it demonstrated much promise. The autopilot that landed the shuttle was able to overcome a 34 mph crosswind to land within 5 feet of the runway center line. Also, of the 38,000 heat shield tiles that covered Buran, only 5 were missing.

Cancellation

After the first flight of Buran, funding for the project was cut. Although the project wasn't officially canceled until 1993, much of the work was halted long before that date. There were two other Buran shuttles under construction. The second orbiter, "Ptichka" ("Little Bird" in Russian) was originally scheduled for completion in 1990. The third Buran was due in 1992. Neither was finished. In November 1995, the partially completed shuttles were dismantled at their production site. The manufacturing plant is scheduled to be converted for production of buses, syringes, and diapers.

Soviet space shuttle to be resurrected

Russia plans to reassert itself as a major power in space by resurrecting the Buran space shuttle, a relic of the Soviet era. It will pay for the development programme in part by taking more space tourists like Dennis Tito up to the space station.

Buran was mothballed in the early 1990s by the cash-strapped Russian government. But with the satellite launching business expanding and the International Space Station running behind schedule, Russian space officials think Buran's time has come.

Last week Energia, the state company which built Buran, opened its hangars at the Baikonur Cosmodrome in Kazakhstan to show Western aerospace engineers that Buran is ready and waiting for relaunch.

"There is a future for this programme," says Leonid Gurushkin, director of launch operations at Baikonur. "Buran is the only launcher with a 100-tonne payload," he says. "By extending the length we can carry 200 tonnes. There is no alternative to Buran and I don't see any coming." The largest load possible in a Western launcher is little more than 20 tonnes.
Solo flight

So far, the giant craft has made only one flight, in 1988. Flying without a crew, it orbited the Earth twice, before landing on a purpose-built strip at Baikonur.

Energia built two Buran shuttles and three main boosters to carry them. While the Soviet Union was crumbling around them, Energia's engineers continued to get funding because the military saw Buran as vital to any missile defence system similar to America's Star Wars. Buran's only imported component was heat-resistant paint.

The Buran project would have employed 30,000 people, and there were plans for up to 30 launches a year. The new Russian government finally cut off funding in 1992.

Now the buildings where Buran was designed and built are being renovated to accommodate Western engineers who come to Baikonur for commercial satellite launches by Russian Proton rockets. The 4.5-kilometre landing strip that was built for Buran was recently refurbished by an American company to land Russian Antonov cargo aircraft, the only planes large enough to carry big satellites.
Ready to go

Like all Russian space vehicles, and the nuclear-armed missiles on which they were based, Buran is assembled horizontally and moved by rail to the launch pad, where it is raised to vertical. The process takes only a few days.

All the necessary machinery is still in place at Baikonur, and the hangars are stacked with spare rocket motor parts and fuel tanks.

"The launcher is powered by hydrogen, oxygen and kerosene," says Gurushkin. "The strap-on boosters are reuseable. They drop back to the airstrip. In fact only the core unit is lost."

Energia thinks there is now a role for Buran because the International Space Station is creating the need to carry ever larger loads into low orbit. "We have been dreaming of this time," says Gurushkin.

Secrets revealed

Russia's other state space company, Khrunichev, is a rival to Energia, but its director Alexander Kondratiev says he welcomes any opportunity for Russian space engineers to compete with the West on an equal footing.

"Until 1990 we couldn't tell anyone what we were doing. But now we can show the world our worth," he says.

Ironically, the money for Buran's revival will be coming from the West. In the past 17 months, Russian Protons have launched 17 commercial satellites, earning Russia more than $100 million per launch.

And despite NASA's opposition, Gurushkin says Russian flights to the space station will soon carry more space tourists. "We already have many applications. We are currently considering them all and will take whoever pays most," he says.
