Target entity: Chandra’s Surface Thermophysical Experiment
Context triple: [Chandra’s Surface Thermophysical Experiment, fullName, Chandra’s Surface Thermophysical Experiment]
  • A. Chandra’s Surface Thermophysical Experiment chosen
    Chandra’s Surface Thermophysical Experiment is a scientific instrument on India’s Chandrayaan-2 lunar mission designed to study the Moon’s surface temperature and thermal properties.
  • B. Thermal Emission Imaging System
    The Thermal Emission Imaging System (THEMIS) is a multispectral infrared and visible-light camera on NASA’s Mars Odyssey orbiter used to map Martian surface composition, temperature, and geological features.
  • C. Planetary Instrument for X-ray Lithochemistry
    Planetary Instrument for X-ray Lithochemistry (PIXL) is a micro-focus X-ray fluorescence spectrometer on NASA’s Mars Perseverance rover designed to map the elemental composition of Martian rocks and soil at fine scales to investigate past habitability.
  • D. Moon Mineralogy Mapper
    Moon Mineralogy Mapper is a NASA-designed imaging spectrometer that mapped the Moon’s surface composition in detail, notably helping confirm the presence of water and hydroxyl on the lunar surface.
  • E. Station Explorer for X-ray Timing and Navigation Technology
    Station Explorer for X-ray Timing and Navigation Technology (SEXTANT) is a NASA demonstration mission that tests the use of X-ray pulsars for autonomous spacecraft navigation in space.
  • F. None of above.
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
