Zvezda (ISS Module)

Zvezda (ISS Module)

Zvezda (Russian: Звезда, meaning "star"), DOS-8, also known as the Zvezda Service Module, is a component of the International Space Station (ISS). It was the third module launched to the station, and provides all of the station's life support systems, some of which are supplemented in the USOS, as well as living quarters for two crew members. It is the structural and functional center of the Russian portion of the station - the Russian Orbital Segment.

The module was manufactured by RKK Energia, with major sub-contracting work by GKNPTs Khrunichev. Zvezda was launched on a Proton rocket on July 12, 2000 and docked with the Zarya module on July 26. The rocket used for the launch was one of the first to carry advertising; it was emblazoned with the logo of Pizza Hut restaurants, for which they are reported to have paid more than US$1 million.
