How this entity was disambiguated
This entity first appeared as the object of triple T3615055 — 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.
Mars Reconnaissance Orbiter
Mars Reconnaissance Orbiter is a NASA spacecraft launched in 2005 that studies Mars’ atmosphere, climate, and surface in high detail while serving as a key communications relay for other Mars missions.
-
B.
Luna spacecraft
The Luna spacecraft were a series of Soviet robotic probes launched between the late 1950s and 1970s that achieved many lunar exploration firsts, including the first human-made object to reach the Moon and the first soft landing on its surface.
-
C.
Deep Space Climate Observatory
The Deep Space Climate Observatory (DSCOVR) is a NOAA and NASA satellite positioned at the Sun–Earth L1 Lagrange point that continuously monitors solar wind conditions and provides real-time space weather and Earth observation data.
-
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.
Dawn mission
The Dawn mission was a NASA space probe that studied the two largest bodies in the asteroid belt, Vesta and Ceres, to investigate the conditions and processes of the early solar system.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: Lunar Reconnaissance Orbiter Description of subject: Lunar Reconnaissance Orbiter is a NASA robotic spacecraft launched in 2009 to map the Moon’s surface in high detail and search for resources such as water ice.
