International Space Station
Zvezda

Zvezda (Russian: Звезда, lit. ' star ') launched in July 2000, is the core of the Russian Orbital Segment of the ISS. Initially providing essential living quarters and life support systems, it enabled the first continuous human presence aboard the station. While additional modules have expanded the ISS's capabilities, Zvezda remains the command and control center for the Russian segment and it is where crews gather during emergencies.

A descendant of the Salyut programme's DOS spacecraft, Zvezda was built by RKK Energia and launched atop a Proton rocket.
