Soyuz 1



The mission objective of Soyuz 1 was developmental testing of the spacecraft systems and components in space flight conditions. The Soyuz 1 was piloted by cosmonaut V. M. Komarov, who had made a flight in a Voskhod spaceship. On April 24, after 24 hr (18 orbits), cosmonaut Komarov successfully accomplished retrofire, and Soyuz 1 made a safe reentry into the dense layers of the atmosphere. Communications continued normally, with the temporary blackout as the spacecraft passed through the upper atmosphere where the external antennas were burned off. Based on monitored conversations, Komarov was fully functioning throughout the flight and rode the ship down alive and conscious. However, because of a failure in the parachute system, the main parachute did not deploy on schedule. The high descent velocity resulted the destruction of the ship and the death of cosmonaut Komarov.
