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.
In 2020, Trident was selected along with three other Discovery proposals for further study, with two expected to be selected to fly as Discovery 15 and 16.[5] On 2 June 2021, NASA selected the Venus missions DAVINCI+ and VERITAS over Trident and the Io Volcano Observer.[6]
