Zvezda (ISS module)

List of ISS modules

Zvezda (Russian for star Звезда ) is the Russian residential and navigation module of the International Space Station ( ISS), built by RKK Energia. It was launched on 12 July 2000 by a Proton -K rocket from Baikonur. Zvezda is about 13.1 meters long, has a maximum diameter of 4.15 meters, a weight of just 19.1 tonnes and is a modified version of the basic module of the Mir space station. The module has four coupling units, three passive type " SSWP M - 8000" on the spherical transition portion at the bow and a passive type " SSWP G4000 " at the rear. There are also connections and pumps, which transfer the delivered fuel to the tanks of the module Zarya. Unmanned Transportation (Progress, ATV), which are all about active coupling assemblies of the type " SSWP G4000 " feature, create here. It can dock the type Soyuz also manned spacecraft. Such a maneuver by the approach control systems course and Toru are supported.

Zvezda is composed of three compartments. After the spherical transition part follows the cylindrical body and a likewise cylindrical, of sealed rear section, which serves as an exit gate and storage space. In the central part there are control devices, life support, toilets and shower facilities, a kitchen, training equipment and more campers.

With the headboard Zvezda was connected to the in- space since November 1998 Zarya module. When pairing on July 26 Sarja took the active role in the final phase. On the other two connectors should according to original planning "up" a power supply module (NEM) with a lattice mast, eight solar panels ( about 20 kilowatts ) and a manipulator and "down" a universal docking and storage module (UDM ) Docking, in which additional facilities should be located to preserve life. 2001, both the power supply module, as well as the UDM was removed and cut in half the number of solar panels. The NEM module was finally built yet and was named Rassvet. It has been associated with the shuttle mission STS- 132 2010 for the station and docked to the nadir piece of the Zarya module. There is a second coupling module Poisk, which docked in 2009 at the upper interface port of Zvezda. Currently, the " bottom " piece from the first coupling module Pirs ( Docking Compartment 1 ) shows that both for docking incoming vessels serves as the function of a pressure lock fulfilled. The end of 2011 or later Pirs is to be replaced by a larger Russian research module called Nauka.

Zvezda itself has two solar panels with an average electrical power of about five kilowatts and is equipped with a developed in Germany intelligent data management system.
