Scientists firm up flyby plan for New Horizons’s next destinationSeptember 21, 2017 Stephen Clark
(...) New Horizons will make its
closest approach to 2014 MU69 at 0533 GMT (12:33 a.m. EST) on Jan. 1, 2019, according to Alan Stern, the mission’s principal investigator from the Southwest Research Institute. The flyby will occur in the late evening on New Year’s Eve in the other U.S. time zones. (...)
Once the probe’s dish-shaped antenna is trained back on Earth, imagery and data will begin to trickle down soon after the flyby, making the six-hour trip at light speed at a rate of just 1 to 2 kilobits per second.
At that downlink speed, it will take more than a year-and-a-half to return all the scientific goods gathered by New Horizons. (...)
The spacecraft has enough hydrazine fuel and electrical
power from its plutonium generator to remain functional until around 2035, Stern said, potentially giving the probe enough reserves to adjust its course to fly by another Kuiper Belt Object after MU69. (...)
New Horizons awoke from hibernation Sept. 11 for three months of scientific observations of Kuiper Belt Objects, a software update, and a course correction maneuver Dec. 9. It will go back into hibernation Dec. 22 until waking up again June 4 to begin flyby preparations. (...)

(...) At present, New Horizons can remain operational until roughly 2037 – another 20 years.
However, to accomplish a third – or even fourth, according to Stern – flyby of a KBO, New Horizons will require an additional mission extension, possibly more than one. (...)
The current mission extension, for the MU69 flyby, lasts until 2021. (...)
