1970—BORN OUT OF CHAOS—SALYUT—SOVIET GOVERNMENT

After the disasters of the Soyuz 1 and N-1, and the continuing disagreements between Mishin and Chelomei, the Soviet government decided that the rival teams should pool resources, under the program name DOS, in order, finally, to get the space station project off the ground. The basic Almaz design was thought to be sound and was kept, but the TKS ferry was thought to be too complicated for rapid develop­ment, and so modifications were made to the Almaz design to allow it to accept a Soyuz as the crew ferry. Other changes included replacing Chelomei’s design for propulsion with the proven Soyuz engine module,

The result of this enforced collaboration was Salyut 1, the first chapter in the story of manned space stations.
