Interstellar Boundary Explorer

Target entity: Interstellar Boundary Explorer
Context triple: [NASA Heliophysics System Observatory missions, includesMission, Interstellar Boundary Explorer]

• A. Mercury Magnetospheric Orbiter
  Mercury Magnetospheric Orbiter is a Japanese-built spacecraft designed to study Mercury’s magnetic field and space environment as part of the joint ESA–JAXA BepiColombo mission.
• B. Parker Solar Probe
  Parker Solar Probe is a NASA spacecraft designed to study the Sun’s outer atmosphere by flying closer to it than any previous mission, enduring extreme heat and radiation to investigate solar wind and space weather.
• C. Juno spacecraft
  The Juno spacecraft is a NASA space probe designed to study Jupiter’s composition, gravity field, magnetic field, and polar magnetosphere to better understand the planet’s origin and evolution.
• D. 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.
• E. 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.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: Interstellar Boundary Explorer
Target entity description: Interstellar Boundary Explorer (IBEX) is a NASA spacecraft mission designed to map and study the outer boundaries of the heliosphere where the solar wind meets interstellar space.
