Soyuz 3 was a spaceflight mission launched by the Soviet Union on 26 October 1968. Flown by Georgy Beregovoy, the Soyuz 7K-OK spacecraft completed 81 orbits over four days. The 47-year-old Beregovoy was a decorated World War II flying ace and the oldest person to go into space up to that time. The mission achieved the first Russian space rendezvous with the uncrewed Soyuz 2, but failed to achieve a planned docking of the two craft.

Beregovoy and Soyuz 3 came back to earth on 30 October 1968, after completing 81 full orbits of the Earth. The descent module landed near the city of Karaganda in Kazakhstan, cushioned by a blizzard's snowfall. Despite subzero temperatures, Beregovoy's landing was so easy he said later that he hardly felt the impact at all. The Soviets hailed Soyuz 3 as a complete success. Beregovoy was promoted to Major General and named director of the national Center for Cosmonaut Training at Star City.

This is Soyuz's 9th flight, and 2nd crewed flight.

The Soyuz is a Soviet crewed spaceship, developed to made manned lunar missions. This version called 7K will fly 4 times on the giant launcher N1, and several tens of times on Proton to fly over the Moon, which will be successful during the mission Zond 4. Soyuz will become the first spacecraft to transport living beings to the Moon during the flight of Zond 5, with two turtles. Subsequently, it is adapted to low orbit and will fly on the Soyuz launcher to serve the Salyut and Mir stations and the ISS.
