Full Resolution So much content in Leslie Young's notes at K-3 days. The big things: "Derek: Could start seeing PSF broadening" -- i.e., we're starting to get close enough that MU69 is no longer a point. And of course: "3:48 PM Alan: CONFIRMED -- ENCOUNTER MODE" -- i.e., New Horizons is on course to fly past Arrokoth and observe it, and the encounter is completely out of our hands from here on out.
