The mission has been prolonged till April 2021 and, whether it is nonetheless operational at the moment, it will likely be renewed.
He might have sufficient to go to a 3rd KBO, however within the mid-2030s, he’ll not have the plutonium 238 powering his thermoelectric radioisotope generator (RTG.)
In 2038, New Horizons shall be 100 AU from the Solar and might be able to discover the outer heliosphere very similar to the Voyager spacecraft.
