How this entity was disambiguated
This entity first appeared as the object of triple T13252701 — 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.
Luna program launch vehicles
Luna program launch vehicles were the Soviet rockets, primarily based on the R-7 family, developed under Sergei Korolev to send the first robotic spacecraft to the Moon during the early space race.
-
B.
Electron launch vehicle
The Electron launch vehicle is Rocket Lab’s small, two-stage orbital rocket designed for frequently launching lightweight satellites and payloads to low Earth orbit.
-
C.
Artemis launch vehicles
Artemis launch vehicles are NASA’s heavy-lift rockets developed to support the Artemis program’s crewed and cargo missions to the Moon and beyond.
-
D.
Gemini 2
Gemini 2 was an uncrewed test flight in NASA's Gemini program that validated the spacecraft’s heat shield and reentry systems in preparation for later crewed missions.
-
E.
Epsilon launch vehicle
The Epsilon launch vehicle is a Japanese solid-fuel rocket designed for cost-effective, small satellite launches into orbit.
- F. None of above. chosen

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: Gemini launch vehicles Description of subject: Gemini launch vehicles were a series of modified Titan II rockets used in the 1960s to send NASA’s two-person Gemini spacecraft into Earth orbit as part of the early U.S. human spaceflight program.
