NASA's New Horizons May Shift Toward Kuiper Belt

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

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 space agency announced it has selected the potential next destination for the New Horizons mission, a small Kuiper Belt object (KBO) known as 2014 MU69 that orbits nearly a billion miles beyond Pluto.

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.

Similar to the asteroid belt, the Kuiper Belt it is far larger -- 20 times as wide and 20 to 200 times as massive, according to a report from the Institute for Astronomy at the University of Hawaii.

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."

Re: Stay Closer to Home
@Gary_EL I don't think I'm wrong when I say that to become a "spacefaring race", we need to master human hibernation, and most likely going faster than 58,536 km/h; which is the New Horizon's escape trajectory.
Here is a nice take on human hibernation:

@Whoopty I read that the New Horizon will reach the KBO in 2020, and its official mission will end in 2026.
And I thought the probe was in its last legs after Pluto!

Decades of use
As long as the power sources last, New Horizons has many years and potentially decades of use to mankind as it explores the far reaches of our solar system and beyond. I'm really excited to see what else it sends back over the next year though. I imagine some of the up close images of Pluto will be astounding.

Stay Closer to Home
It sounds contradictory to say so when talking about space missions, I know. But, anything out that far will have to be all robots, not humans. What I want to see is people going to space, with robots used when to do so would be advantageous, just like here on Earth. I want us to become a spacefaring race, not merely a race that sends out machines.
