Zvezda (meaning Star) is a Russian "service module" that was launched to dock with the International Space Station (ISS) by a Proton-K rocket from Baikonur at 04:56 UT. It is to be a primary and vital component of ISS at least during its construction phase, providing life-support function and electrical power for all other modules, enabling command and control, and providing residential quarters for the working crew. The 20 ton module has three docking hatches and 14 windows. It was once being built as a replacement for the aging Mir. It carries about four thousand instruments and machinary units, compared to 1,500 in Zarya and 235 in Unity. It docked with the Zarya module automatically at 01:45 UT on 26 July. The first construction crew of three is expected to reach the ISS on a Soyuz craft on 30 October 2000. Currently, the vision, mission, and goal of ISS remain as its successful construction by 2005.
