NASA's New Horizons team is plotting to swing the spacecraft past the exotically named 2014 MU69 in the Kuiper Belt.
NASA's New Horizons Brings Pluto Into Focus

Call it a galactic victory lap. Following New Horizon's astoundingly successful flyby of the solar system's ninth planet -- or dwarf planet, depending on which camp you belong to -- NASA scientists are turning the spacecraft towards a new target.
The Kuiper Belt region of the solar system is located beyond the planets, extending from the orbit of Neptune to approximately 50 astronomical units (AU) from the Sun. One AU is equivalent to the distance between Earth and the Sun.
The New Horizons team must write a proposal to the agency to fund the KBO mission. That is due next year and will have to be evaluated by an independent team of experts before NASA can decide about the go-ahead.
"Even as the New Horizon's spacecraft speeds away from Pluto out into the Kuiper Belt, and the data from the exciting encounter with this new world is being streamed back to Earth, we are looking outward to the next destination for this intrepid explorer," John Grunsfeld, astronaut and chief of the NASA Science Mission Directorate at agency headquarters in Washington, wrote in an Aug. 28 statement.
"While discussions whether to approve this extended mission will take place in the larger context of the planetary science portfolio, we expect it to be much less expensive than the prime mission while still providing new and exciting science."
The spacecraft was originally designed to fly beyond the Pluto system and explore additional Kuiper Belt objects. It carries extra hydrazine fuel for a KBO flyby.
In addition, its communications system is designed to work from far beyond Pluto, its power system is designed to operate for many more years, and its scientific instruments were built to operate in light levels much lower than it will experience during the 2014 MU69 flyby.
The planning for the next stage of New Horizons' mission has been in the works since 2011. It employed high-powered terrestrial telescopes and the Hubble Space Telescope. Meanwhile NASA scientists are still waiting for the spacecraft to transmit the bulk of the images and other data stored on its digital recorders from its July encounter with the Pluto system.
"2014 MU69 is a great choice because it is just the kind of ancient KBO, formed where it orbits now, that the Decadal Survey desired us to fly by," New Horizons principal investigator Alan Stern, of the Southwest Research Institute (SwRI) in Boulder, Colo., said in a statement. "Moreover, this KBO costs less fuel to reach [than other candidate targets], leaving more fuel for the flyby, for ancillary science, and greater fuel reserves to protect against the unforeseen."
