NASA’s New Horizons spacecraft encounter with “Ultima Thule” – a Kuiper Belt object that orbits one billion miles beyond Pluto – and the farthest space probe flyby in history.
Added good news is that New Horizons principal investigator and planetary scientist, Alan Stern, is prepared for puzzlement.

I discussed this new and imminent record-setting flyby with Stern, fleshing out what’s ahead for this trailblazing probe – at Ultima Thule…and beyond.

re: extended mission #2
message for ALEX PARKER, SCIENTIST IN MARYLAND OR COLORADO
Alex parker mentioned the LORRI camera on new horizons has discovered 55 Kuiper objects near MU 69 AND new horizon’s trajectory. How many of these new objects are within the “cone of accessibility” for a second extended mission flyby between 2021 and 2025?. There still seems to be a lot of hydrazine fuel on board the spacecraft for a next flyby encounter.
