Soyuz T-9

Soyuz T-9 lifts off from the Soviet Union, bringing a new long-term crew to space station Salyut 7. Cosmonauts Vladimir Lyakhov and Aleksandr Aleksandrov take up residence on Salyut 7 for a 150-day stay, including work aboard the recently-docked Kosmos 1443 temporary space station module. The disastrous failure of the next Soyuz mission to reach orbit means that Lyakhov and Aleksandrov spend their entire stay in orbit with no visits from other crews. They return to Earth on November 23rd.
