An unusual advertisement has appeared on one of the trading platforms in Russia. A private individual from St. Petersburg is offering to purchase an auxiliary engine from the Soviet Buran reusable orbital spacecraft.
Specific equipment rarely falls into private hands, usually remaining at closed Roscosmos enterprises or in museum collections.
The unit put up for sale is not a main engine, but an important element of the control system. Gas-dynamic steering engines were used to allow the ship to change orientation, dock, and maneuver in orbit.
In total, there were 38 such engines of various thrusts located in the tail and nose of the Buran. The seller claims that the specimen has retained its factory markings, representing a huge collector's value for fans of the history of cosmonautics.
