Neptune has been directly explored by one space probe, Voyager 2, in 1989. As of 2024 [update] , there are no confirmed future missions to visit the Neptunian system, although a tentative Chinese mission has been planned for launch in 2024. [ 1 ]
Montage of planets and some moons that the two Voyager spacecraft have visited and studied. It is the only program that visited all four outer planets. A total of nine spacecraft have been launched on missions that involve visits to the outer planets; all nine missions involve encounters with Jupiter, with four spacecraft also visiting Saturn.
This is a list of all spacecraft landings on other planets and bodies in the Solar System, including soft landings and both intended and unintended hard impacts.The list includes orbiters that were intentionally crashed, but not orbiters which later crashed in an unplanned manner due to orbital decay.
The James Webb Space Telescope has captured its first image of Neptune, and it's the best view of the planet's rings in over 30 years.
NASA's James Webb Space Telescope has provided an image of Neptune that shows the planet's rings — the clearest view in more than 30 years.
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 ...
Neptune's rings and moons viewed in infrared by the James Webb Space Telescope. Neptune has a planetary ring system, though one much less substantial than that of Saturn and Uranus. [168] The rings may consist of ice particles coated with silicates or carbon-based material, which most likely gives them a reddish hue. [169]
The last time Neptune's rings were seen in detail was during a flyby in 1989 by NASA's Voyager 2 spacecraft as it journeyed beyond the solar system and into interstellar space. That historic flyby ...
