"Mir" Orbital Complex (USSR)
longitudinal axis on the instrument-cargo compartment. The nominal location of Kvant-2
within Mir was along -Y axis.
Kristall module was intended to conduct technological and other scientific research and
experiments to support dockings with the vehicles outfitted with androgynous peripheral
docking assemblies. The module consisted of two pressurized compartments, i.e. instrument-
cargo and transfer-docking compartments. The module had three docking assemblies, i.e. axial
active assembly on the instrument-cargo compartment and two androgynous peripheral
docking assemblies on the transfer-docking compartment (axial and lateral). The nominal
position of the Spektr module as part of the MIR Station was along the -Z axis.
Spektr module was intended to conduct scientific research and experiments to investigate
Earth resources, proper external atmosphere of the orbital complex, geophysical processes of a
natural and artificial origin in a near-earth space and in the upper Earth atmosphere, as well as
resupply the station with additional electric power supplies. The module consisted of two
compartments, i.e. pressurized instrument-cargo and unpressurized compartment, on which
two major and two additional solar arrays and science instruments were mounted. The module
had one active docking assembly, located along its longitudinal axis on the instrument-cargo
compartment. The nominal position of the Spektr module as part of the MIR Station was along
the -Y axis.
Docking Compartment (developed at S.P. Korolev RSC Energia) was intended to support
dockings of the U.S. Space Shuttle Orbiters to the MIR Station without modifying its
configuration. It was delivered to orbit by the U.S. Atlantis Orbiter (STS-74) and docked to the
Kristall module (- Z axis).
Priroda module was intended to conduct science research and experiments to investigate
Earth resources, upper Earth atmosphere, space radiation, geophysical processes of a natural
and artificial origin in a near-earth space and in the upper Earth atmosphere. The module
consisted of one pressurized instrument-cargo compartment. The module had one active
docking assembly located along its longitudinal axis. The nominal location of the Priroda
module within the MIR Station was along the -Z axis.
During the MIR Station operation absolute world records of man's continuous on-orbit stay-
time were achieved:
1987 - Yuri Romanenko (326 days 11 hrs 38 min)
1988 - Vladimir Titov, Musa Manarov (365 days 22 hrs 39 min)
1995 - Valery Polyakov (437 days 17 hrs 58 min).
In 1995 Valery Polyakov also became an absolute world record-breaker in total on-orbit stay
time, in 1999 his achievement was exceeded by Sergey Avdeev:
Valery Polyakov - 678 days 16 hrs 33 min (for 2 flights)
Sergey Avdeev - 747 days 14 hrs 12 min (for 3 flights).
Among women world records of space flight duration were achieved by:
Elena Kondakova (169 days 05 h 1 min) in 1995
Shannon Lucid, the USA (188 days 04 hrs 00 min, including a stay-time on the MIR Station of
183 days 23 hrs 00 min) in 1996.
