Soyuz TM-6 was the sixth mission to Mir space station. The mission began on June 7, 1988, 14:03:13 UTC, launching Commander Vladimir Lyakhov, Flight Engineer/Research Doctor Valeri Polyakov and Research Cosmonaut Abdul Mohmand, the first Afghan cosmonaut, into orbit. They docked with Mir two days later, meeting with the long-duration resident crew. During their 7-day stay there, cosmonauts performed Earth observation and other tasks. They returned on a Soyuz TM-5 spacecraft, landing safely back on Earth on September 7, 1988, 00:49:38 UTC.
