Orbital periods:

Charon - 6.3872304 +/- 0.0000011 days

S/2005 P2 - 24.8562 +/- 0.0013 days

S/2005 P1 - 38.2065 +/- 0.0014 days

Alan Stern Said: ....only HST was capable of the task, and it found them in just 8 minutes flat.

Once again we're reminded of the usefulness of Hubble, and the need of one repair mission to keep it going.
And no I cant place any bets on being alive in 2016, facts speaks against that so I close the book on Pluto by going with the 'collision created theory' for Charon and the two new moons.

Now, now, one must remain an optimist. You never know what surprises lie in store in the near fututre. And if we don't figure it out with HST or some creative use of other instruments prior to NH, then there is always the possibility that Vulcans will land in Montana next year and take some of us on a tour of our solar system. Then you'll have your answers. (So be prepared to tell them how to pronounce "Quaoar" when you get there.)
