Is it time to return to Neptune and its largest satellite, Triton? When Voyager 2 flew over Neptune and Triton 30 years ago, it raised more questions than it answered. Maybe we can get some of the answers in 2038.
NASA is considering the next mission of the Discovery project, with four candidates: studying Venus’s atmosphere, observing volcanic activity on Jupiter’s moon Io, mapping Venus’ surface map and geology, and exploring The Neptune’s satellite Triton.
Triton’s mission is called Trident. Neptune is a rarely visited gas planet, and in fact only one spacecraft has visited it: Voyager II, which flew over Neptune in 1989, giving us a glimpse of its strange satellite, Triton.
If it can overcome the other three candidate missions, Trident plans to launch in 2026, taking advantage of a rare alignment between Jupiter, Neptune and Triton in 2038.
