Target entity: Neutral Gas and Ion Mass Spectrometer
Context triple: [MAVEN, instrument, Neutral Gas and Ion Mass Spectrometer]
  • A. Neutral Gas and Ion Mass Spectrometer chosen
    The Neutral Gas and Ion Mass Spectrometer is a scientific instrument designed to measure the composition and isotopes of neutral gases and ions in a planetary atmosphere, such as that of Mars.
  • B. Energetic Particle and Plasma Spectrometer
    The Energetic Particle and Plasma Spectrometer is a scientific instrument designed to measure high-energy particles and plasma environments in space, notably used aboard NASA’s MESSENGER mission to study Mercury’s magnetosphere and solar wind interactions.
  • C. Solar Wind Ion Composition Spectrometer
    The Solar Wind Ion Composition Spectrometer is a scientific instrument on NASA’s ACE spacecraft that measures the elemental and ionic composition of the solar wind to study the Sun and heliospheric processes.
  • D. Solar Wind Ion Analyzer
    The Solar Wind Ion Analyzer is a scientific instrument designed to measure the properties of solar wind ions, such as their composition, energy, and direction, to study their interaction with planetary atmospheres and magnetic fields.
  • E. Mercury Atmospheric and Surface Composition Spectrometer
    The Mercury Atmospheric and Surface Composition Spectrometer is a scientific instrument on NASA’s MESSENGER spacecraft designed to analyze Mercury’s thin atmosphere and surface materials using ultraviolet and visible-light spectroscopy.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
