Adventures of Space

Salyut 1  ( DOS-1 ) was the first  space station  of any kind, launched into  low Earth orbit  by the  Soviet Union   on April 19, 1971. The  Salyut program  followed this with five more successful launches of seven more stations. The final module of the program,  Zvezda (DOS-8)  became the core of the Russian segment of the  International Space Station  and remains in orbit. ~Salyut 1 as seen from Soyuz 11
