Infact I've recently rejoined the 'Eyes...' team (only part of my time) and one of my first tasks was to take a nominal observation plan for the flyby and start parsing it down to the elements needed for 'Eyes.....' - so it's happening smile.gif

Eyes was created by Doug--so he can efficiently do this task. Outreach and public engagement are a high priorities for New Horizons and both Rover missions (sadly not all space missions). Can't imagine Doug wasting his time on anything he chooses to do....

Ultima in View:

http://pluto.jhuapl.edu/News-Center/News-A...p?page=20180828

its was about 24 minutes of exposure time needed.

Amazing news !

For comparsion in 2015 Plutos moons Nix and Hydra was about a little more distance at these pictures:

http://pluto.jhuapl.edu/News-Center/News-A...p?page=20150218

But they only needed a 50 second exposure.

It looks like Ultima is smaller in size than Nix and Hydra..and of course more far from the sun..but I think most goes to the smaller size of Ultima.

Good Luck NH !

Two items for you all:

1. Nix and Hydra are prolly ~1.5-2x bigger diameters than Ultima, but also much higher albedos.
2.The stellar occultation was successful from Senegal. Results will be announced when we have them. Not yet. But the successful detection in Senegal plus the fact that Ultima was in *precisely* the predicted pixel in this first OpNav imaging attempt with LORRI means our orbits solutions for Ultima from HST are not bad!
