ISS: Zvezda module launched

ISSThe third major piece of the International Space Station, the Mir-derived Zvezda service module, is launched from Russia. Once in orbit, automatic systems guide Zvezda toward rendezvous and docking with the combined Zarya and Unity modules that currently comprise the station. Zvezda adds life support systems and living quarters, as well as additional power-generating solar panels, to the station, completing the most basic building blocks necessary for ongoing occupation.
