Context triple: [Titan’s north polar seas, mappedBy, Cassini radar altimetry]
  • A. Radar for Europa Assessment and Sounding: Ocean to Near-surface
    Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) is an ice-penetrating radar instrument on NASA’s Europa Clipper spacecraft designed to probe Europa’s icy shell and search for evidence of a subsurface ocean and its structure.
  • B. Mapping Imaging Spectrometer for Europa
    The Mapping Imaging Spectrometer for Europa is a remote-sensing instrument on NASA’s Europa Clipper spacecraft designed to map the moon’s surface composition and search for signs of habitability by analyzing reflected light across a wide range of wavelengths.
  • C. Mars Advanced Radar for Subsurface and Ionosphere Sounding
    Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) is a radar instrument designed to probe beneath the Martian surface and study its ionosphere by transmitting low-frequency radio waves from orbit.
  • D. Titan’s north polar seas
    Titan’s north polar seas are vast, methane- and ethane-filled bodies of liquid clustered around the north pole of Saturn’s largest moon, including its largest sea, Kraken Mare.
  • E. Mercury Laser Altimeter
    The Mercury Laser Altimeter is a scientific instrument designed to map Mercury’s surface topography with high precision by measuring the time it takes laser pulses to return from the planet’s surface.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
