None of the users gave a reliable answer. Please research.But as far as I know, there is no new missions to Neptune?
No spacecraft have directly visited Neptune. The only close-up observations of the planet were made by NASA's Voyager 2, which flew by Neptune on August 25, 1989. This flyby provided valuable data about the planet's atmosphere, rings, and moons, but no missions have been sent specifically to study Neptune since then. Future missions to explore Neptune are still being discussed by space agencies.
Neptune has never been visited by humans. All of the other planets in our solar system have been the target of various robotic missions, but Neptune remains unexplored by humans.

There have been no astronauts that have gone to Neptune. Nor is there any space exploration projects or programs called Neptune that I am aware of.
As of now, no satellites or robots have been sent specifically to Neptune. The only spacecraft to have visited Neptune is NASA's Voyager 2, which conducted a flyby in 1989, providing valuable data and images of the planet and its moons. Since then, there have been discussions about potential future missions, but none have been realized yet.
