After achieving Neptune orbit, the orbiter will conduct at least 46 flybys of Triton over the four-year main science phase, achieving near-global coverage of the moon while simultaneously studying Neptune and other moons. The orbiter would then orbit progressively closer to Neptune and its rings on a "Grand Finale" similar to the 612:
at Jupiter, but this would require launch prior to 2032. A 220 kg (490 lb) atmospheric probe will be released from the orbiter before orbital insertion at Neptune and descend for around 37 minutes into Neptune's atmosphere to study its composition, dynamics, and processes, sending data at
