Argo (NASA spacecraft)
2009 NASA spacecraft mission concept
Argo was a 2009 spacecraft mission concept by NASA to the outer planets and beyond.[1][2][3] The concept included flybys of Jupiter, Saturn, Neptune, and a Kuiper belt object.[1] A focus on Neptune and its largest moon Triton would have helped answer some of the questions generated by Voyager 2's flyby in 1989,[1] and would have provided clues to ice giant formation and evolution.[2]
