While on board, the crew conducted an extensive programme of geophysical and astrophysical research, experiments on biology and biotechnology and work on space materials science. They started the commercial production of crystal in highest quality for a US electronics company. A protein grow experiment was also profitable (25 million rubels). A first EVA was conducted on 17 July 1990, lasting 7h 16m, in which Soyuz TM-9 was repaired after three of eight thermal blankets had come loose near the heat shield. Another EVA was performed on 26 July 1990 (3h 31m), in order to repair the Kvant2 Module hatch, but this failed.
The crew left on Soyuz TM-9 on 9 August 1990. The expedition in total lasted 179 days, 1 hour and 17 minutes. The crew completed 2833 orbits of the Earth.
