Kvant 2

Part of the Mir Space Station program

Kvant 2 was the second addition to the Mir core module and is attached to a radial docking port of the core module's transfer compartment. Based on a transport logistics spacecraft originally intended for the Salyut station program, it is designed to host life science, materials science, and Earth observation experiments. It also carries a substantial amount of equipment to improve living conditions and operations in the overall complex including electrolysis units to provide oxygen from recycled water, a water supply system, two water regeneration systems, sanitation facilities, a shower, and a compartment designed to enhance EVAs.

The module has is divided into three pressurized compartments: instrumentation/cargo, science instruments and an airlock. The total pressurized volume is 61 cubic meters. The airlock provides EVA capability and also contains a cosmonaut maneuvering unit that increases the range and complexity of tasks that can be attempted during EVA.

The module originally docked on December 6, 1989 at the forward axial port on Mir core module. It was transferred to its permanent location on a core module radial port on December 8, 1989.
