Launch from Baikonur; landing with
Soyuz 27-spacecraft 310 km west of
Tselinograd.
Docking on space station
Salyut 6;
staying time there: 95 days.
EVA by
Grechko on 20.12.1977 (1h 28m), inspecting the Salyut 6
docking port. The inspection confirmed that the
Soyuz 25 spacecraft docking unit was
at fault in its failure to hard dock, and that its docking attempts had left
the Salyut 6 front port undamaged. Visits from
Soyuz 27 on 10.01.1978 and from
Soyuz 28 since 02.03.1978; common
scientific work and experiments.
It was the first mission to receive
visiting crews launched aboard another spacecraft, and to be resupplied by a
logistics spacecraft (Progress 1) on 20.01.1978, delivering food, water, air
and fuel. The crew also set a new flight duration record.
