-
A.
Cassini radar altimetry
chosen
Cassini radar altimetry is a remote sensing technique used by the Cassini spacecraft to measure Titan’s surface elevations and map features such as its north polar seas through radar reflections.
-
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.
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.
-
D.
Shangri-La dune fields on Titan
The Shangri-La dune fields on Titan are vast equatorial expanses of dark, organic-rich sand dunes on Saturn’s largest moon, considered a prime site for studying prebiotic chemistry and targeted for exploration by NASA’s Dragonfly mission.
-
E.
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.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
