Soyuz 1 - Background

Background

Soyuz 1 was the first manned flight of the first-generation Soyuz 7K-OK spacecraft and Soyuz rocket, designed as part of the Soviet lunar program. It was the first Soviet manned spaceflight in over two years, and the first Soviet manned flight following the death of the Chief Designer of the space program Sergey Korolyov. Komarov was launched on Soyuz 1 despite failures of the previous unmanned tests of the 7K-OK, Cosmos 133 and Cosmos 140. A third attempted test flight was a launch failure; a launch abort triggered a malfunction of the launch escape system, causing the rocket to explode on the pad. The escape system successfully pulled the spacecraft to safety.

Prior to launch, Soyuz 1 engineers are said to have reported 203 design faults to party leaders, but their concerns "were overruled by political pressures for a series of space feats to mark the anniversary of Lenin's birthday." It is not clear how much of this pressure resulted from the need to continue beating the United States in the Space Race and have Soviets first on the Moon, or to take advantage of the recent setbacks in the U.S. space program with the Apollo 1 disaster.

Yuri Gagarin was the backup pilot for Soyuz 1, and was aware of the design problems and the pressures from the Politburo to proceed with the flight. He attempted to "bump" Komarov from the mission, knowing that the Soviet leadership would not risk a national hero on the flight.

Mission planners intended to launch a second Soyuz flight the next day carrying cosmonauts Valery Bykovsky, Yevgeny Khrunov, and Aleksei Yeliseyev, with Khrunov and Yeliseyev scheduled to do an EVA over to Soyuz 1.
