Soyuz-TM 8



Alexander Viktorenko and Alexander Serebrov were launched from the Baikonur Cosmodrome aboard Soyuz TM-8. Their arrival at Mir on September 7 was preceded by a new class Progress supply vehicle. Progress M-1 docked with the front axial port of the space station August 25. Soyuz TM-8 berthed at the aft port 2 weeks later. Because of misalignment on approach, automatic docking was aborted. The cosmonauts manually guided the 7,150-kg transport the last few meters to the docking unit, completing the connection at 22:25. After reactivating the dormant station, Viktorenko and Serebrov spent their first weeks in orbit making stellar observations and performing microgravity experiments. Preparing for the next module addition to the complex, they replaced Mir's computer memory with an upgrade version accounting for the mass of an expanded station -- data required for accurate maneuvers. On December 12th, the crew backed Soyuz TM-8 away from Mir's aft port. The station was rotated 180 deg., allowing Soyuz to redock at the forward port, making room at the rear for Progress M-2.
