Voyager 2 wasn't "sent" to Neptune in the sense of a specific person or group making that decision. It was a product of a complex scientific endeavor with many people involved.

Here's a breakdown of who played key roles:

* NASA: The National Aeronautics and Space Administration was the primary agency responsible for the Voyager program. They funded and managed the mission.

* Jet Propulsion Laboratory (JPL): JPL, a NASA facility, designed, built, and operated the Voyager spacecraft.

* Scientists and engineers: Hundreds of scientists and engineers from various disciplines contributed to the mission's success, including:

* Mission planners: Responsible for designing the trajectory and orchestrating the encounter with Neptune.

* Instrument developers: Created the scientific instruments that gathered data about Neptune.

* Data analysts: Processed and interpreted the data sent back from the spacecraft.

* Flight controllers: Operated the spacecraft and kept it on course.

Therefore, it's more accurate to say that the Voyager 2 mission to Neptune was a collective effort of NASA, JPL, and numerous scientists and engineers.
