Soyuz 6



Soyuz 6 was piloted by cosmonaut G. Shonin, Commander, and cosmonaut V. Kubasov, Flight Engineer. The announced mission objectives included (1) checkout and flight test of space borne systems and the modified structure of the Soyuz craft, (2) further inprovement of the control, orientation, and orbital stabilization systems and navigation aids, (3) debugging the piloting systems by orbital maneuvering of the spaceships in relation to one another, (4) testing of a system for control of the simultaneous flight of three spacecraft, (5) scientific observations and photographing of geological-geographical subjects and exploration of the earth's atmosphere, (6) studying circumterrestrial space, and (7) conducting experiments of engineering research and biomedical importance. Stable two-way radio communications was maintained between the spaceships and the ground stations, and TV coverage was broadcast from the ships during flight. The most significant objective was testing alternate methods for welding using remote handling equipment in the high vacuum and weightless conditions of outer space. In Soyuz 6, the welding unit had the name Vulcan and was controlled remotely by electric cable. Of the three types of welding tried (low pressure compressed arc, electron beam, and arc with a consumable electrode), electron beam was the most successful. Soyuz 6 also performed group flight with Soyuz 7 and Soyuz 8, but it did not dock with either spacecraft.
