The Russian Orbital Segment (ROS) is the name given to the components of the International Space Station (ISS) constructed in Russia and operated by the Russian Roscosmos. The ROS handles Guidance, Navigation, and Control for the entire Station.

The segment currently consists of six modules, which together essentially comprise the base configuration of the cancelled Russian space station Mir-2. The segment is controlled directly from Roskosmos’s Mission Control Center in Moscow. The six modules are:

Zarya (dawn)
Zvezda (star)
Poisk (search)
Rassvet (sunrise, dawn)
Nauka (science)
Prichal (berth)
