Crewed spacecraft of the Soyuz programme to dock with Salyut 1 space station
Soyuz 7K-OKS
(also known as
Soyuz 7KT-OK
)
[1]
is a version of the
Soyuz spacecraft
and was the first spacecraft designed for
space station
flights. Its only crewed flights were conducted in 1971, with
Soyuz 10
and
Soyuz 11
.
Design
[
edit
]
The two craft of the Soyuz 7K-OKS generation were modified from the original
Soyuz 7K-OK
. The new
"probe and drogue" docking mechanism
, which was first used by these two missions, featured an internal docking hatch that allowed for the first time internal transfer between Soviet spacecraft. This "probe and drogue" docking mechanism introduced with Soyuz 7K-OKS is still in use today at the
International Space Station
(ISS). The external toroidal fuel tank, a holdover from the original lunar mission models of the Soyuz, was dropped from the 7K-OKS since it was unneeded for
Earth orbital flights
.

Flights
[

]
The Soyuz 7K-OKS flew only twice,
Soyuz 10
and
Soyuz 11
.
[1]
On its maiden flight, the Soyuz 7K-OKS successfully launched into Earth orbit, but failed to dock completely with the
Salyut 1
space station. Upon reentry, the spacecraft encountered problems with toxic fumes.
[2]
This generation of Soyuz spacecraft is notable for the first successful delivery of crew to the first space station
Salyut 1
by Soyuz 11 ? this success was however overshadowed by the death of the crew, who were killed when the capsule depressurised during the
re-entry
phase.
