More than nine years in flight, many more years before that in the making--this is the time. Please post all comments related to New Horizon's passage through the Pluto system here.

What to expect

Reminder that despite the rather brief duration of the actual encounter, it will be literally months before all acquired data is returned so this thread will be active for an equivalent time. Intrepid TPS space journalist and UMSF admin Emily Lakdawalla has written an excellent guide to planned imagery activities. EDIT: Updated version of guide. Emily has also produced a simulation of the kinds of images that are anticipated.

FAQs

Most Forum members are advanced spaceflight enthusiasts; many are in fact professionals in space-related disciplines. Accordingly, there are no plans to post answers to questions that can be easily answered via a Google search, and we ask that everyone please attempt to do so before posting a question.

EDIT (4 Jul 15): Admin Astro0 has produced an extensive New Horizons FAQ thread.

EDIT: Review rule 1.9 and keep it firmly in mind before posting. Posts violating that rule will be deleted without notice.

____

With all that said, the most important thing by far is to witness the marvel of discovery, of exploration, of New Horizons on worlds never before seen. This is the best seat in the house for doing so, right in the comfort of our own homes. As with previous major events in planetary exploration over the past decade it is likely that not only professionals but also the press may be watching the Forum during the coming days due to its hard-earned reputation as a place for noise-free commentary and stunning contributions by amateur image processors, so please bear this in mind...

...and I can't stop smiling with anticipation and excitement. smile.gif What marvelous things we will soon see. Enjoy the ride!!!


--------------------
A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

One tidbit I liked from the AMA session yesterday was that at some point they might adjust the spacecraft clock in order to deal with uncertainties in Pluto's position. I assume that is partially because it's a low-risk, low-bandwidth change, and also because the biggest uncertainty is along the radial axis?
