Trident takes advantage of an efficient gravity assist alignment of Jupiter and Neptune (that occurs once every 13 years) to capitalize on a narrow observational window that enables assessment of changes in Triton's plume activity and surface characteristics since the previous encounter of Neptune-Triton by Voyager 2 in 1989.

Pluto, with Cerberus at his side, is shown holding the bident in the mythological ceiling mural painted by Raphael's workshop for the Villa Farnesina (the Loggia di Psiche, 1517–18).

The Trident missile is a submarine-launched ballistic missile (SLBM) equipped with multiple independently targetable reentry vehicles (MIRV). Originally developed by Lockheed Missiles and Space Corporation , the missile is armed with thermonuclear warheads and is launched from nuclear-powered ballistic missile submarines (SSBNs).
Voyager 2 started taking navigation images of Neptune in May 1988. [3] Voyager 2 's observation phase proper of Neptune began 5 June 1989, the spacecraft officially reached the Neptunian system on 25 August, and data collection ceased on 2 October. [4] Initially it was planned to use a trajectory that resulted in Voyager 2 passing around 1,300 ...
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 ...
