Launch from Baikonur; landing with Soyuz
34-capsule 295 km northwest of Dzheskasgan.
DFollowing a one day solo
flight the Soyuz docked with Salyut 6 on 26.02.1979. The cosmonauts became the
third resident crew. During their residence unmanned cargo spacecrafts Progress
5 -7 and unmanned spacecraft Soyuz 34 docked on the station. The Soyuz 34 was
needed, because of the failing docking-attempt of the
Soyuz 33
spacecraft. Soyuz spacecrafts could only be used for 90 days, so a new one
(unmanned) spacecraft was needed.
When they arrived on the station,
they had to make preparing work, because the station had to be repaired (sprung
propellant leak of the propulsion system). The tank repairing took some time,
after the arrival of the Progress 5 spacecraft, but was successful. Testing new
developed Gamma-Ray-Telescope. Experiments in materials science were also
performed. Progress-spacecraft brought 10 m-reflector to the space station,
which unfolded independent at the stations tall. Test of the "Cosmic
Radio-Telescope" (
KRT-10).
Both cosmonauts conducted an
EVA on
15.08.1979 (1h 23m) to jettison the
KRT-10
antenna from rear docking port and to inspect the exterior of Salyut 6. They
also retrieved samples of materials from the stations hull.
All in all
the crew set a new spaceflight record.
