Bulgarian Space Agency (SRI-BAS)

Bulgarian Space Agency is a government space agency, established in 1993, operating out of Bulgaria.

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.
