Mission overview

After docking with the Mir space station by hand (automatic failure), it was put back into operation. In addition to scientific experiments, the fifth permanent crew also carried out maintenance work and renewed some technical systems. The research program envisaged studies in the fields of earth exploration, astronomy, space technology, materials science, biology, medicine, ecology and atmospheric physics.

Another module was added to the station during the mission. Kwant 2 launched on November 26th and docked at Mir's bow ten days later. Another important item on the program was spacecraft work with a total duration of 17 hours and 36 minutes to expand the station and test the autonomous maneuvering device SKP (IKAR). This is a free-flight device equipped with 32 control nozzles and 7 kg of nitrogen as fuel, which should reach a speed of up to 20 km / h relative to the station. With it, the cosmonauts should be able to move to free-flying experimental platforms without using a spaceship. Replenishment was delivered with the transport spaceships Progress M1 and M2. At the end of the mission, the handover to the successor crew took place.
