Bulgaria really made a mark in 1979 when Georgi Ivanov became its first cosmonaut aboard Soyuz 33. That mission put Bulgaria on the map as the sixth country to send someone into space.
A few years later, Aleksandar Aleksandrov expanded those space achievements with his successful trip to the Mir space station in 1988.
On April 10, 1979, Georgi Ivanov took off aboard Soyuz 33 from Baikonur Cosmodrome in Kazakhstan. He teamed up with Soviet commander Nikolai Rukavishnikov for the Intercosmos program.
Things didn’t go smoothly. The spacecraft ran into serious technical issues while approaching the Salyut 6 space station. The main engine failed, so docking with the orbital lab was off the table.
Ivanov and Rukavishnikov had to act fast, executing an emergency return after almost two days in space. Luckily, the backup engine worked during reentry, and they landed safely in Kazakhstan.
Ivanov’s flight made Bulgaria the sixth country to achieve human spaceflight. His 1 day, 23 hours, and 1 minute in space became a huge source of pride for Bulgarians.
This mission happened during the thick of the space race. Bulgaria’s involvement showed just how far Soviet space cooperation reached through Intercosmos.
Aleksandar Aleksandrov became Bulgaria’s second cosmonaut in June 1988. He launched to the Mir space station on Soyuz TM-5 and spent nearly 10 days in space, this time with everything going according to plan.
He docked with Mir and got right to work, running several scientific experiments during his stay.
Aleksandrov focused on materials science and Earth observation studies. His research provided valuable data to both Bulgarian and Soviet space programs.
His smooth mission showed Bulgaria’s ongoing value in international space efforts. The flight also highlighted how much more reliable the spacecraft had become compared to earlier missions.
Aleksandrov’s trip happened while Mir was at its peak, serving as a hub for long-duration spaceflight research. His success really boosted Bulgaria’s reputation in space science and tech.
Bulgaria hit some big milestones through its space program. Joining the group of nations that launched citizens into space was no small feat.
Key Bulgarian Space Achievements:
Both Ivanov and Aleksandrov flew as research specialists, not commanders. Their missions focused on experiments designed by Bulgarian scientists and engineers.
These flights happened during Bulgaria’s communist era, when close Soviet ties opened doors for advanced space tech and training.
Bulgaria’s space achievements inspired a new wave of scientists and engineers. Its cosmonauts became national icons and symbols of what Bulgaria could do, especially during the Cold War.
Every April 10th, Bulgaria celebrates the Day of Bulgarian Cosmonautics, marking Ivanov’s historic flight. Those early missions still shape Bulgaria’s space research today.
Bulgaria started getting serious about space research in the late 1950s. The country built its capabilities through the Bulgarian Academy of Sciences and some dedicated research teams, gradually earning a spot among the world’s space-faring nations.
Bulgaria took its first real step into organized space research by founding the Astronautical Society (BAS) in Sofia on December 8, 1957. That marked the beginning of space science as a focused field in Bulgaria.
This move lined up with the global excitement after Sputnik. Bulgarian scientists saw early on that space research would be important for the country’s future.
