The mission team (and the voting public) have chosen a (temporary?) name for dear little 2014 MU69.

Wow, down to five months already. Can't wait for this. Thank you so much for all you've done, Mr. Stern. James Sontag -------------------- Axes Grind and Maces Clash!

What will the best resolution of Ultima Thule be? How many pixels across? How many meters per pixel?

If we fly the nominal trajectory, the best possible resolution is about 32 meters per pixel, but that's not guaranteed (it requires very precise pointing of our narrow-angle LORRI camera), and those images will by necessity be somewhat underexposed and smeared. The best high-quality, high-probability, images on the nominal trajectory, with the wide-angle MVIC camera, will be about 130 meters per pixel. MU69/Ultima is about 30 km across, so our best images could be anywhere between 900 and 230 pixels across.

Thanks! How many useful images do you think you'll get?

Great Expectations: Plans and Predictions for New Horizons Encounter with Kuiper Belt Object 2014 MU69 ('Ultima Thule')
QUOTE In this letter we begin with a brief overview of cold classical KBOs, of which Ultima is a prime example. We give a short preview of our encounter plans. We note what is currently known about Ultima from earth-based observations. We then review our expectations and capabilities to evaluate Ultima's composition, surface geology, structure, near space environment, small moons, rings, and the search for activity. https://arxiv.org/abs/1808.02118 |

The New Horizons Kuiper Belt Extended Mission S.A. Stern, H.A. Weaver, J.R. Spencer, H.A. Elliott, the New Horizons Team (Submitted on 21 Jun 2018) The central objective of the New Horizons prime mission was to make the first exploration of Pluto and its system of moons. Following that, New Horizons has been approved for its first extended mission, which has the objectives of extensively studying the Kuiper Belt environment, observing numerous Kuiper Belt Objects (KBOs) and Centaurs in unique ways, and making the first close flyby of the KBO 486958 2014 MU69. This review summarizes the objectives and plans for this approved mission extension, and briefly looks forward to potential objectives for subsequent extended missions by New Horizons.
