As of 2024, there are no confirmed future missions to visit the Neptunian system, although a tentative Chinese mission has been planned for launch in 2024. [1] NASA, ESA, and independent academic groups have proposed future scientific missions to visit Neptune. Some mission plans are still active, while others have been abandoned or put on hold.
Voyager 2 is the only space probe to have visited the Neptune system, completing a flyby on August 25, 1989. An orbiter to Neptune was considered as part of the aborted Mariner Mark II program in the 1990s, and several mission concepts for an orbiter were developed in the 2000s, including a concept by the California Institute of Technology [4] and a version by the University of Idaho and ...
NASA initially directed the TRW Company to develop the Pioneer spacecraft to ensure that future missions could withstand the intense radiation belts of Jupiter. [1] Each 571 lb (259 kg) spacecraft was equipped with 11 instruments to conduct close-up studies of Jupiter and interplanetary space during transit.

Flew past Miranda, Ariel, Umbriel, Titania and Oberon. Closest approach at 17:59 UTC on 24 January 1986. Later flew past Neptune. [9]
Trident is a space mission concept to the outer planets proposed in 2019 to NASA's Discovery Program. [ 3 ] [ 4 ] The concept includes flybys of Jupiter and Neptune with a focus on Neptune's largest moon Triton .
This is a list of space probes that have left Earth orbit (or were launched with that intention but failed), organized by their planned destination. It includes planetary probes, solar probes, and probes to asteroids and comets, but excludes lunar missions, which are listed separately at List of lunar probes and List of Apollo missions.
Comparison of NASA Mercury, Gemini, Apollo, and Space Shuttle spacecraft with their launch vehicles. This is a list of NASA missions, both crewed and robotic, since the establishment of NASA in 1957. There are over 80 currently active science missions. [1]
Voyager 1 and 2, probes by NASA designed to explore the outer planets that have since passed the boundary between the heliosphere and interstellar space. Trident, a concept by NASA to explore Neptune and Triton, which would have been launched in 2025 on a trajectory to reach Triton in mid-2038.
