salyut

And of course Soyuz 1 and Soyuz 11 / Salyut 1; it's not just a problem for America.

In one of the Salyut programs, there was a loss of power which caused the station to freeze over.

Ever since Soyuz 11 depressurized after/while detaching from Salyut 1, everyone has used rescue suits during launch/landing.

This actually happened with Salyut 7: the station died on orbit, no electrical or anything.

Yeah, interesting, at least some cosmonauts on Salyut stations explicitly used legs to float around...

The first one, KRT-10, was attached to Salyut 6 orbital space station in 1979.

Mir 1 had the DOS-7 module, the previous modules were the Salyut stations.

The article for some reason doesn't show Soviet Salyut stations in the timeline.

We didn't learn any of that from the ISS which we didn't already know from Salyut 6 and 7, and Mir.

Non-cooperative docking has only been done exactly once in the history of human spaceflight on the Soyuz T-13 mission to the Salyut 7 space station [0].

This has been done before in the US Skylab program and the Soviet Salyut and Mir programs, although never in the same scale as the ISS.

Additionally the Soviets did the exact same, with Mir being launched prior to the Buran’s first test flight — heck Salyut 1 was launched in 1971.

Around half of the "Salyut" space stations were actually military "Almaz" stations (Salyut 2, 3, and 5), at least one of which was armed with a fully automatic cannon designed to engage other spacecraft.

Saturn-V couldn't carry a mission to repair Hubble Space Telescope similar to Soyuz mission to repair Salyut-7?

Even with those, I'm not sure there was really any big discovery since the previous Mir/Salyut/Skylab decades of orbital hanging around.

I think Apollo trumps Mir/Salyut/Almaz, and I think Voyager 2 alone trumps the entire Soviet unmanned space program, even the Venera missions.
