Soyuz 1 Crash Site

Soyuz 1 Crash Site

Space disaster that put back Soviet lunar program 18 months. Soyuz 1 was to dock with Soyuz 2 and transfer crew. Instead Soyuz 1 solar panel didn't deploy; manual reentry; tangled parachute lines; astronaut killed on impact with earth.

AKA: Rubin (Ruby). Launched: 1967-04-23. Returned: 1967-04-24. Number crew: 1 . Duration: 1.12 days.

Soyuz 1 as active spacecraft was launched first. Soyuz 2, with a 3 man crew would launch the following day, with 2 cosmonauts spacewalking to Soyuz 1. However immediately after orbital insertion Komarov's problems started. One of the solar panels failed to deploy, staying wrapped around the service module. Although only receiving half of the planned solar power, an attempt was made to maneuver the spacecraft. This failed because of interference of the reaction control system exhaust with the ion flow sensors that were one of the Soyuz' main methods of orientation. The decision was then made to bring Komarov back. Re-entry was successful and the drag chute deployed. However due to a failure of a pressure sensor, the main parachute would not deploy. Komarov released the reserve chute, but it became tangled with the drag chute. The descent module crashed into a field near Orenburg at 7 am.

Despite the various failures on the three previous Soyuz 7K-OK test flights (Kosmos 133, Kosmos 140A, and Kosmos 140), Brezhnev and Ustinov pressured Mishin to proceed with an attempt to accomplish the 'all up' manned rendezvous, docking, and crew transfer spectacular that would eventually be accomplished by Soyuz 4 and Soyuz 5. Komarov was the pilot for the Soyuz 1 active spacecraft, which would be launched first. Soyuz 2, with the crew of Bykovsky, Khrunov, and Yeliseyev would launch the following day, with Khrunov and Yeliseyev spacewalking to Soyuz 1 and returning to earth with Komarov. Not only would this mission show the superiority of Soviet technology, compared to that in America just after the Apollo 204 fire, but it would prove several key elements (first orbit rendezvous, crew transfer via spacewalk) of the planned lunar landing mission.

However immediately after orbital insertion Komarov's problems started. One of the solar panels failed to deploy, staying wrapped around the service module. Although only receiving half of the planned solar power, an attempt was made to maneuver the spacecraft. This failed because of interference of the reaction control system exhaust with the ion flow sensors that were one of the Soyuz' main methods of orientation. The decision was then made to bring Komarov back. The first attempt at retrofire however failed - the automatic systems of the ship could not orient it because at the moment of maneuver to retrofire attitude the spacecraft was going through an ion 'pocket' - an area of low density where the sensors could not reliably detect the direction of motion of the spacecraft. A decision was made to make a manual retrofire on the next orbit.

Because the maneuver would be happening on the night side of the earth, Komarov could not use the Vzor optical alignment device to orient the spacecraft for retrofire. A method of alignment by sighting the moon through the periscope (anticipating Apollo 13's manual method by several years!) was hurriedly selected. Belyayev personally assured Ustinov that the method was feasible based on his Voskhod 2 experience. Following approval, Komarov was able to accomplish the manual retrofire using this method.

Re-entry was successful and the drag chute deployed. However due to a failure of a pressure sensor, the main parachute would not deploy. Komarov released the reserve chute, but it became tangled with the drag chute, which had not been released as would have normally occurred on deployment of the main chute. The descent module crashed into a field near Orenburg at 7 am.

The local air force commander reported to the control center only that the cosmonaut would require immediate medical attention, then severed all communication links. Ustinov was told by Kamanin at eleven that Komarov was dead. Ustinov phoned Brezhnev, then in Czechoslovakia, at noon. The world was informed by TASS seven hours later. Komarov's ashes were buried in the Kremlin Wall in a massive ceremony.

Stories prevalent among those who worked at US listening posts in Turkey said that Komarov was infuriated by the balky spacecraft, and went out cursing those who had sent him in such an unready piece of equipment. The Russians claim that the crash site was not thoroughly cleaned up by the recovery teams. A group of Young Pioneers supposedly found some remains of Komarov at the crash site, and gave him a second burial place.
