46 years ago today: Georgi Ivanov became the first Bulgarian cosmonaut

On this day 46 years ago, Georgi Ivanov made history as the first Bulgarian to go into space. On 10 April 1979, at 20:34 Moscow time, the Soyuz-33 spacecraft was launched into orbit with Georgi Ivanov and Soviet commander Nikolai Rukavishnikov on board.

Although the mission suffered a serious technical malfunction that prevented the spacecraft from docking with the Salyut-6 orbital station, the two cosmonauts managed to return safely. After thirty-one orbits, they landed 320 kilometres south-east of Zhezkazgan, Kazakhstan. The mission lasted one day, 23 hours and 1 minute.

Remarkably, Ivanov remained calm throughout the mission - even during the emergency landing - and his pulse never exceeded the normal range. His physiological composure under extreme stress is still considered a world record.
