Flight History
Despite the fact that the Soyuz-10 spacecraft approached the Salyut-1 station, the crew could not go to the station due to problems with the docking station. According to Boris Chertok’s memoirs, the reason for the failure was a mistake made in the control system: after touching and capturing by the passive docking station of the station the pin of the docking station of the ship, the correction system was not turned off. The touch was perceived by the control system as a disturbance that she tried to compensate for by the inclusion of corrective engines. As a result, the Soyuz-10 spacecraft, coupled, but not yet pulled to the Salyut-1 station, under the influence of correction engines strongly deflected first one way, then the other, exceeding the deviation angles acceptable for the docking unit and causing the docking unit to break on the side of Soyuz-10. A lot of the working fluid of the correction system has been used up. The undocking command from the side of the ship did not pass, the undocking command from the side of the station was also not executed. It became clear that a regular undocking is possible only after the docking is normally completed and it is not possible to undock. The astronauts had a backup option: having activated the squibs, “shoot” the docking pin from the Soyuz spacecraft and thus undock with the Salyut-1, but the pin would remain in the Salyut docking station and the other ship could no longer dock with the station, Salyut-1 would be lost. A solution was found on Earth: by installing a jumper in one of the devices, it was possible to open the lock and release the Soyuz-10 spacecraft pin by undocking. On April 24, 1971, Soyuz-10 made the world's first night landing.
According to the results of the flight, the docking unit and the control system of the Soyuz-11 spacecraft were finalized.
