Russian Orbital Segment

Target entity: Russian Orbital Segment
Context triple: [International Space Station modules (NASA segments), connectedTo, Russian Orbital Segment]

• A. Salyut space stations
  The Salyut space stations were a series of Soviet orbital laboratories launched in the 1970s and 1980s that pioneered long-duration human spaceflight and scientific research in low Earth orbit.
• B. Chinese Orbital Segment
  The Chinese Orbital Segment is the modular, permanently crewed portion of China’s Tiangong space station that serves as the nation’s primary long-term human outpost in low Earth orbit.
• C. Soyuz spacecraft
  The Soyuz spacecraft is a long-serving Russian crewed vehicle used to transport astronauts and cosmonauts to and from low Earth orbit, including the International Space Station.
• D. Russian space station Mir
  The Russian space station Mir was a modular, long-duration orbital research outpost that served as the centerpiece of Soviet and later Russian human spaceflight from the mid-1980s until its deorbit in 2001.
• E. ISS module Zarya
  ISS module Zarya is the first module of the International Space Station, providing initial power, propulsion, and storage functions after its launch in 1998.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
