Launch from Baikonur; landing 185 km northwest
of Tselinograd.
The first planned hard-docking on the space station
Salyut failed, because of a malfunction in the docking systems. The hard
docking was needed for the enabling of electrical connections. The reason was a
faulty mechanism on the Soyuz capsule, which was discovered after the following
mission. Another problem of this mission was, that only rookies flew. The rules
were changed, so that a rookie only could fly together with a veteran
cosmonaut. Until the mission of
Soyuz
TM-19 this rules were not changed again.
The premature return to
Earth was without additional more problems.
