Russian Luch relay satellites

Target entity: Russian Luch relay satellites
Context triple: [International Space Station, communicationSystem, Russian Luch relay satellites]

• A. Molniya communications satellites
  Molniya communications satellites are Soviet/Russian spacecraft placed in highly elliptical Molniya orbits to provide long-duration communications coverage over high-latitude regions such as northern Russia.
• B. Lomonosov satellite
  The Lomonosov satellite is a Russian scientific spacecraft designed to study high-energy cosmic rays, gamma-ray bursts, and near-Earth space phenomena.
• C. Alouette satellites
  The Alouette satellites were pioneering Canadian scientific spacecraft launched in the 1960s to study the ionosphere, marking Canada as one of the first nations to design and build its own satellite.
• D. 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.
• E. Lunokhod programme
  The Lunokhod programme was a Soviet series of robotic lunar rover missions in the early 1970s that achieved the first successful remote-controlled exploration of the Moon’s surface.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Russian Luch relay satellites
Target entity description: The Russian Luch relay satellites are a series of geostationary spacecraft that provide data relay and communications links between orbiting spacecraft, such as the International Space Station, and ground control.
