Kvant-2
From Wikipedia, the free encyclopedia
Kvant-2 (Russian: Квант; lit. Quantum) was the third module and second major addition to the Mir space station. Its primary purpose was to deliver new science experiments, better life support systems, and an airlock to Mir. It was launched on November 26, 1989 on a Proton rocket. It docked to Mir on December 6.

[edit] Description
Kvant-2 was the first Mir module based on the TKS spacecraft. Kvant-2 was divided into three compartments. They were the EVA airlock, the instrument/cargo compartment, and the instrument/experiment compartment. The instrument/cargo compartment could be sealed off and act as an extension or a back-up to the airlock. Before Kvant-2 docked to the station, EVAs had to be carried by depressurizing the docking node on the Core Module. Kvant-2 also carried the Soviet version of the Manned Maneuvering Unit for the Orlan spacesuit. It delievered the Salyut 5B computer which was an improvement over the Argon 16B computer already on the station. Kvant-2 had a system for regenerating water from urine and a shower for personal hygiene. It carried six gyrodines to augment those already located in Kvant-1. Unlike Kvant-1, Kvant-2's gyrodines were only accessible from the exterior which turned out to make replacement of failed ones more difficult.
Scientific equipment on Kvant-2 included a high-resolution camera, spectrometers, X-ray sensors, the Volna 2 fluid flow experiment, and the Inkubator-2 unit which was used for hatching and raising quail.
