Spektr
Part of the Mir Space Station program
The Spektr module, the fifth Mir component to attain orbit, is primarily designed for Earth observation (specifically natural resources and atmospheric studies). The module also carries US/Russian equipment for material science, biotechnology, life sciences, and space technology studies. A small airlock and manipulator arm is also available to attach small external experiments and deploy small satellites. The module's total pressurized volume is 62 cubic meters.
The module originally docked with the station on June 1, 1995, and was moved to its permanent location at a Mir core module radial port on June 2, 1995.
Spacecraft
2 3.9 kN main engines and 400N attitude control thrusters (NTO/UDMH) were used for initial approach and docking. 2 27 sq. meter solar arrays (6.9 kW), and 2 38 sq. meter arrays (9.3 kW) are attached to the module. Energy storage is available via a 360 A-hr NiCd battery system.
