Mission overview

Another mission name for the flight is Salyut 6 EP-2 ( Russian Экспедиция посещения 2 - visiting team 2).

With the visit of the Czech intercosmonaut Vladimír Remek as the first non-Soviet cosmonaut and non-US astronaut, the possibilities of the space station were expanded. On the one hand, further propaganda-effective first achievements of socialist states (first flight for the host country in each case) could be achieved, on the other hand, the scientific potential of these countries after the first unmanned satellites was also tapped for manned space flight. The rules of the Interkosmos organization were further developed. Both the course of the missions and the propaganda design (e.g. press work) were based on the experiences of the Soyuz Apollo project .

The core of the relatively uniform Interkosmos missions were therefore the original broadcasts of the start, discussions with the respective party or state leaders and greetings to the home population. In addition, observations and recordings (with the MKF-6 camera also multispectral) of the guest's home country, medical-biological examinations and experiments with products typical of the country were carried out. The guest visit was designed for about 7 days and 21.5 hours (with a tolerance of +/- one hour). The preparation of these missions did not take a lot of time, as military pilots who were mostly trained in the Soviet Union (i.e. who had language skills) could be used.

In the case of Soyuz 28, the party leaders were Leonid Brezhnev and Gustáv Husák . The national experiments dealt with material science.

The mission was successfully completed on March 10, 1978 with the landing in the Kazakh steppe. Just eight days later, the regular team Georgi Grechko and Juri Romanenko also landed . Certainly urgent for the latter, as he had contracted a tooth infection that could not be adequately treated in the ward.
