Script error New Horizons 2 (also New Horizons II, NHII, or NH2) was a proposed mission to the trans-Neptunian objects by NASA. It was conceived as a planetary flyby mission in 2002.[1][2] In March 2005, the proposal was not selected for further development because of a shortage of plutonium-238 needed for the radioisotope thermoelectric generator (RTG).[3]


New Horizons 2 was included in the tentative budget for the New Horizons missions.[4] In 2004 the United States Senate Appropriations Committee provided additional funding for New Horizons 2, a new Kuiper belt mission.[5] As early as 2004 there was a conference on how to make the most use of New Horizons 2's Uranus flyby.[6]

Candidate targets included Template:Mpl-, a system that, like Pluto–Charon, contains multiple bodies.[4] The mission plan for Template:Mp also included flybys of Jupiter and Uranus,[4] and perhaps four Kuiper belt objects (KBO).[7] There was a lot of flexibility: even without a gravity assist any KBO within 50 AU and a 20-year flight time was possible.[8] A flyby of Neptune's Triton was also considered, with 66652 Borasisi as a potential follow on.[8] Template:Mpl- was also considered to be visited, having a similar flight plan as Template:Mp.[9]
