Mission overview

Arzebarski and Krikaljow replaced the old crew, the British Sharman returned with them after a week-long flight in the Mir space station. The mission, paid for by British companies, mainly involved biological and chemical experiments. Helen Sharman also gave a lesson that was broadcast live to British classrooms.

For the ninth permanent crew, experiments in astronomy, biology, chemistry, earth exploration, space technology, materials science and medicine were on the program. In addition, the cosmonauts carried out maintenance work and changed several devices for new systems. Their outboard work to repair an antenna for the course approach system on the Kwant module and to assemble a 14-meter-long foldable lattice mast made of a novel titanium-nickel alloy for an additional control unit on the Kwant module was also important. With a total of six exits, the two cosmonauts worked 32 hours and 23 minutes in space. During their mission, they received supplies from the Progress M-8 and M-9 transport spacecraft . Sergej Krikaljow had to stay in space six months longer than planned, as the next two planned missions were merged due to lack of funds and therefore only one member of the regular crew could be replaced.
