Over 20 years ago, on May 14th, 1981, the first cosmonaut from Romania went to space on board Soyuz 40. One day later, the Soyuz spacecraft docked with space station Salyout 8. For five days, Prunariu, his soviet commander Leonid Popov and the permanent crew onboard the space station, Vladimir Kovalyonok and Victor Savinykh worked on scientific experiments.

On May 22nd Prunariu and Popov returned to earth. Starting with the very flight, Prunariu’s home country Romania has been honouring him and his flight with numerous postmarks. In this article, Romanian collector Grecu Dan gives an overall account of all postmarks used to commemorate space mission Soyuz 40. German member Jurgen Peter Esders translated the text from French.

Together with his backup, Pilot-Engineer Dumitru Dediu, he takes part in training and preparation at Yuri Gagarin Cosmonaut Training Centre at Star City near Moscow from March 1978 to May 1981.
