From an article posted on the New Horizons website on November 5, 2015.

NASA’s New Horizons spacecraft has successfully completed record-setting maneuvers that have set it on course to reach 2014 MU69, which orbits in the Kuiper Belt, in January 2019.

The four propulsive maneuvers were the most distant trajectory corrections ever performed by any spacecraft. The fourth and final maneuver started at approximately 1:15 p.m. EST on Wednesday, Nov. 4, and lasted just under 20 minutes. Data indicating that this final maneuver had been successful reached spacecraft operators at the Johns Hopkins University Applied Physics Laboratory (APL) in Laurel, Maryland, just before 7 p.m. EST on Wednesday.

The maneuvers didn’t speed or slow the spacecraft, rather they “pushed” New Horizons sideways, giving it a 57 meter per second (128 mile per hour) nudge toward the KBO. 2014 MU69 is around 1 billion miles beyond Pluto, and the aim is for New Horizons to come within even closer range of MU69 than it did to Pluto on July 14, 2015.

The New Horizons team will submit a formal proposal to NASA for the extended mission to 2014 MU69 in early 2016. Curt Niebur, New Horizons program scientist at NASA Headquarters in Washington said that “this is another milestone in the life of an already successful mission that’s returning exciting new data every day. These course adjustments preserve the option of studying an even more distant object in the future, as New Horizons continues its remarkable journey.”

At the time of November 5th’s maneuver, New Horizons was approximately 84 million miles beyond Pluto and nearly 3.2 billion miles from Earth. The spacecraft is now 895 million miles from MU69, speeding at more than 32,000 miles per hour toward deeper space.
