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!

Thanks for sharing the presentations Alan, that's quite an amazing setup!
BTW I remember you mentioning somewhere that NH would take farthest ever image of Earth (surpassing the famous Voyager pale blue dot photo). Is that shot still on the books or are you planning a "One Last Thing" surprise for 2019?!

Pretty crazy feat going on right now....


I imagine they will have to program the spacecraft to make its own decisions in case they get to close because of the 6 hour signal delay. We wont even know its successful until a day afterwords.
This is mindbogglingly complex. if you think about it. This is not like the voyagers, this is open heart surgery with the patient on the moon.

Hats off the team. Cannot wait to see Mu69...


on that note. Is there anything we know of after Ultima Thule?

I know fuel reserves are really low.

Yes, we plan that but much later because we want to try for yet another flyby and the look back observations are so close to the Sun that they could damage our cameras.

Wow, I had no idea this was even on the cards!

Would a search for possible candidates wait until all the Ultima Thule data is safely back on Earth, and the health of the spacecraft and available fuel is assessed? or are efforts already in progress as regards booking time on Earth-based telescopes and Hubble?

I imagine there would be an extremely narrow 'cone of possibility' as regards reaching another KBO with the remaining fuel.

51 days to go to the main event - can't wait!
