Re: Khrunichev's history photo archive

I was unclear -- the 1985 'loss' of control was due to human error,
the later loss of the station -- long after it had been shut down -- was
due to the eventual breakdown of on-orbit hardware.

Here's the full text of the manned space station section, for discussion.
Several eye-opening claims, including that the loss of Salyut-7 was
due to a Mission Control Center human error.

That's not what I read. First:

However, on February 11, 1985, an error made by the Mission Control
Center led to a loss of communication with the unmanned Salyut-7.

Which caused general system failure, but from which state the station was
recovered. Then:

However, in December 1989, the TKS power system failed, and in 1990 a
peak in the solar activity led to a sharp slowdown of the station. That
was why on February 7, 1991, there occurred an uncontrolled deorbiting of
the Salyut-7 - Kosmos-1686 complex, and it ceased to exist.

Nothing about MCC error, human or otherwise, in this second event.
