    Soviet Used Soyuz 7K-OK Hydrogen Peroxide Thruster, 10.5" x 6.5" x 4". In December 1963, the Soviet government approved the 7K-OK, a three-manned orbital version of the Soyuz spacecraft. This manned spacecraft would be the first to complete automated orbital rendezvous, docking, and crew transfer. The initial manned launch of the Soyuz occurred on April 23, 1967. Numerous test flights of the Soyuz reentry capsule were performed prior to this mission. In November 1966, when the capsule's reserve parachute failed at an altitude of 1,500 meters, the resulting crash was attributed in part to a venting of the hydrogen peroxide reaction control system fuel, which burned the parachute lines. When Soyuz 1 was launched with a single cosmonaut, Vladimir Komarov, aboard, both parachutes failed during his return, resulting in the first fatality in the history of manned spaceflight. Soviet space equipment rarely is offered on the market. This hardware is part of a Soyuz hydrogen peroxide thruster. Evidence of its use suggests that it was involved in at least one of the test flights.
