STEREO mission

Target entity: STEREO mission
Context triple: [Max Planck Institute for Solar System Research, participatedIn, STEREO mission]

• A. SOHO mission
  The SOHO mission (Solar and Heliospheric Observatory) is a joint ESA–NASA space observatory launched in 1995 to study the Sun’s interior, atmosphere, and solar wind, greatly advancing our understanding of solar physics and space weather.
• B. Solar Orbiter mission
  The Solar Orbiter mission is a European Space Agency-led spacecraft project designed to study the Sun up close, including its poles and heliosphere, to better understand solar activity and its effects on the solar system.
• C. Deep Space Climate Observatory
  The Deep Space Climate Observatory (DSCOVR) is a NOAA and NASA satellite positioned at the Sun–Earth L1 Lagrange point that continuously monitors solar wind conditions and provides real-time space weather and Earth observation data.
• D. BepiColombo mission
  The BepiColombo mission is a joint ESA–JAXA spacecraft mission designed to study the planet Mercury’s composition, magnetic field, and environment through dual orbiters.
• E. Great Observatories program
  The Great Observatories program is a NASA initiative comprising a suite of space-based telescopes operating across different regions of the electromagnetic spectrum to provide complementary views of the universe.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: STEREO mission
Target entity description: The STEREO mission is a NASA-led solar observatory project using twin spacecraft to provide stereoscopic views of the Sun and its coronal mass ejections, improving understanding and forecasting of space weather.
