Metop satellites

Target entity: Metop satellites
Context triple: [European Organisation for the Exploitation of Meteorological Satellites, operates, Metop satellites]

• A. 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.
• B. Pleiades Earth observation satellites
  The Pleiades Earth observation satellites are a pair of high-resolution French optical imaging spacecraft that provide detailed, frequently updated views of the Earth's surface for civilian and defense applications.
• C. 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.
• D. Terra satellite
  Terra is a flagship NASA Earth observation satellite that carries multiple instruments to monitor the planet’s climate, land, oceans, and atmosphere from polar orbit.
• E. Sapphire (satellite)
  Sapphire is a Canadian military surveillance satellite designed to track space objects and contribute to space situational awareness.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
