Aleksandrov was born in Omurtag, Bulgaria on December 1, 1951. He graduated from the Bulgarian Air Force Academy in 1974 and obtained a degree in technical sciences in 1983. In the Bulgarian Air Force, Aleksandrov rose to the rank of lieutenant colonel.
On June 7, 1988, Aleksandrov launched aboard TM-5 as a Research Cosmonaut along with mission commander Anatoly Solovyev and Viktor Savinykh. Upon arriving at Mir, Aleksandrov became the first Bulgarian to reach a Soviet space station, as the Soyuz 33 mission carrying Georgi Ivanov failed to reach the Salyut 6 space station. On June 17, Aleksandrov returned aboard Soyuz TM-4 along with his fellow crew members. He, along with his crew-mates, spent just under 10 days in space.
Bulgarian Space Agency
The Bulgarian Space Agency has put two Bulgarians onto the ISS in tandem with the Russian Space Agency. Their involvement in space began with the Interkosmos program that helped Communist Bloc countries get access to Soviet space technology. They contributed cosmonauts for a training class, two of which flew aboard the ISS.
