In essence, the Mir manned station not only concentrated
the experience of solving various applied tasks in orbital
flight conditions but also extended the sphere of applying
scientific methods in space, that had been beyond the reach
of Mankind before.
When performing research, a thorny, not simple way has been
passed: from 1.5 ton of science hardware used to perform
astrophysics observations aboard the Salyut orbital station
to 11.5 ton of special-purpose loads of the Mir station.
