Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Reaction Wheel Assembly on Hubble Space Telescope | Statement: [STS-109, componentReplaced, Reaction Wheel Assembly on Hubble Space Telescope]

Target entity: Reaction Wheel Assembly on Hubble Space Telescope
Context triple: [STS-109, componentReplaced, Reaction Wheel Assembly on Hubble Space Telescope]

• A. Hubble Space Telescope Fine Guidance Sensors
  The Hubble Space Telescope Fine Guidance Sensors are high-precision optical instruments that both keep Hubble accurately pointed at astronomical targets and serve as scientific tools for measuring stellar positions and distances.
• B. Spacelab instrument pointing system
  The Spacelab instrument pointing system was a precision guidance and control platform that allowed scientific instruments on Spacelab to be accurately aimed and stabilized for observations in space.
• C. Fine Guidance Sensor
  The Fine Guidance Sensor is a high-precision pointing and stabilization instrument on the James Webb Space Telescope that locks onto guide stars to keep the observatory accurately aimed during observations.
• D. Hubble Space Telescope data electronics
  Hubble Space Telescope data electronics are the onboard systems responsible for processing, storing, and transmitting the telescope’s scientific observations and operational data back to Earth.
• E. Voyager 2 attitude control system
  The Voyager 2 attitude control system is the spacecraft’s subsystem responsible for precisely orienting and stabilizing the probe in space so its instruments and communications antenna remain correctly pointed.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Reaction Wheel Assembly on Hubble Space Telescope
