Planned Soyuz 1/2 duration
« on: 09/10/2017 01:16 PM »
I am posting this here rather than in the "history" section because it will be seen here by more Russian space programme "specialists".

Do we know for certain from reliable Soviet/Russian sources how long the flights of Soyuz 1 and Soyuz 2 were planned to last?   I have seen different data from different sources.

The docking missions of Cosmos 186/188 and Cosmos 212/213 had the dockings take place during the first circuit of the second spacecraft of each pair being launched.   It would be reasonable if this had also been the plan for Soyuz 1/2 (and maybe the planned pair of unmanned satellites which would have included Cosmos 133).   If Soyuz 2 had docked with Soyuz 1 on the former's first circuit then the EVA could have followed fairly quickly, allowing Soyuz 1 to come down after two days in orbit, rather than 3 days which we saw on Soyuz 4.   With this scenario, Soyuz 2 could have returned after just one day in orbit, although it might have remained in orbit for two days as well (we have not had more than one Soyuz spacecraft return to Earth on the same day - of course the twin Vostoks came down on the same days).

I first suggested the two days mission for Soyuz 1 in my 1987 article in Space magazine, but I am not aware of any definitive information about the planned durations of Soyuz 1 and Soyuz 2.

Any information quoting unimpeachable (is there such a word?) Soviet/Russian sources would be most welcome!   Thank you.
