New Horizons 2
It was conceived as a planetary flyby mission in 2002, based on the New Horizons spacecraft, which was in development at the time.[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] The New Horizons 2 study was funded by the New Frontiers program, and delivered to the U.S. Congress in June 2005.[5] In 2004, the United States Senate on Appropriations Committee provided additional funding for New Horizons 2, a new Kuiper belt mission.[5] The mission plan for Lempo also included flybys of Jupiter and Uranus,[5] and perhaps four Kuiper belt objects (KBO).
