Target entity: Heterodyne Instrument for the Far Infrared
Context triple: [HIFI, fullName, Heterodyne Instrument for the Far Infrared]
  • A. Imaging IR Spectrometer
    The Imaging IR Spectrometer is a Chandrayaan-2 orbiter instrument designed to map the Moon’s surface composition by measuring reflected and emitted infrared radiation.
  • B. Palomar Testbed Interferometer
    The Palomar Testbed Interferometer is an astronomical interferometer designed to combine light from multiple small telescopes to achieve extremely high angular resolution for precision measurements of stars and other celestial objects.
  • C. MicrOmega infrared imaging spectrometer
    The MicrOmega infrared imaging spectrometer is a mineralogical instrument designed to analyze the composition of Martian surface materials at microscopic scale aboard the Rosalind Franklin rover.
  • D. Far Infrared Absolute Spectrophotometer
    The Far Infrared Absolute Spectrophotometer (FIRAS) was a key instrument on NASA’s COBE satellite designed to precisely measure the spectrum of the cosmic microwave background, confirming its near-perfect blackbody nature.
  • E. Narrabri Stellar Intensity Interferometer
    The Narrabri Stellar Intensity Interferometer was a pioneering astronomical instrument in Australia that used intensity interferometry to measure the angular diameters of hot stars with unprecedented precision.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
