How this entity was disambiguated
This entity first appeared as the object of triple T18367238 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Lunar Orbiter Laser Altimeter
The Lunar Orbiter Laser Altimeter is a laser-based mapping instrument that precisely measures the Moon’s surface topography and shape from lunar orbit.
-
B.
Lunar Reconnaissance Orbiter Mini-RF instrument
The Lunar Reconnaissance Orbiter Mini-RF instrument is a synthetic aperture radar payload designed to map the Moon’s surface and search for water ice, particularly in permanently shadowed polar regions.
-
C.
Lunar Seismic Profiling Experiment
The Lunar Seismic Profiling Experiment was a geophysical investigation deployed during Apollo 17 to study the Moon’s shallow subsurface structure by recording seismic waves from controlled explosive charges.
-
D.
Mini-SAR (Chandrayaan-1)
Mini-SAR (Chandrayaan-1) is a NASA-provided synthetic aperture radar instrument flown on India’s Chandrayaan-1 lunar orbiter to map the Moon’s polar regions and search for water ice deposits.
-
E.
Lunar Prospector
Lunar Prospector was a NASA lunar orbiter mission that mapped the Moon’s surface composition and gravity field and provided strong evidence for the presence of water ice at the lunar poles.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
