How this entity was disambiguated

This entity first appeared as the object of triple T3064204 — 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.

NED1 Entity disambiguation (via context triple) gpt-5-mini-2025-08-07

Target entity: Orion Launch Abort System
Context triple: [Space Launch System, launchEscapeSystem, Orion Launch Abort System]

A. Orion spacecraft
The Orion spacecraft is NASA’s next-generation crewed space vehicle designed to carry astronauts beyond low Earth orbit on deep-space missions, including journeys to the Moon and eventually Mars.
B. Starship Human Landing System
The Starship Human Landing System is NASA’s selected lunar lander variant of SpaceX’s Starship spacecraft, designed to transport astronauts between lunar orbit and the Moon’s surface for Artemis missions.
C. Exploration Upper Stage
The Exploration Upper Stage is a powerful second stage designed to enhance NASA’s Space Launch System rocket’s capability to send heavier payloads and crewed missions deeper into space, including to the Moon and beyond.
D. Orbital Test Vehicle
The Orbital Test Vehicle is an unmanned, reusable spaceplane developed for the U.S. Air Force and Space Force to conduct long-duration, classified orbital missions and technology demonstrations.
E. Space Launch System
The Space Launch System is NASA’s next-generation heavy-lift rocket designed to carry astronauts and large payloads beyond low Earth orbit, including missions to the Moon and eventually Mars.
F. None of above. chosen
G. Unsure - the case is ambiguous/there is not enough information to decide.
