QUOTE (James S. @ Oct 13 2014, 03:54 PM)  I don't think most people realize that we will be the first humans to ever see Pluto. Man, just thinking about that is crazy. You should have been around for the Voyagers spacecraft, and the first close-up views of so many planets and their moons. Completely new landscapes on a yearly basis that had never been seen before by any human in history. You are right. It is mind-blowing! |

considering i had just turned 10 by Aug ( v2) and sep (v1 ) of 1977
when the Voyagers launched ..... that era was a "time" the 1976 things and goings on Viking Voyager some of the Mariner missions All the astronomy books i could get my hands on were being OUTDATED by the time that a 8 to 12 year old could read them |

Been seeing new worlds for the first time since Mariner 9.

Went to Pasadena from France on a B707 to be part of Planetfest 89 for VII Neptune encounter...was to be the last for a loooong time...and here we (nearly) are. Thank you Mr Stern and All...

Is there going to be another planetfest like gathering for the Pluto flyby?

I'm sure there will be.
Here in Australia, back in the day, Voyager was making its flyby through the Neptunian system. Our ABC (Australian Broadcasting Corp) had a 2 hour special. It was evening over here in Western Australia and we had a special public night (Monday) to view Neptune, btw, I'm a member of the Astronomical Society of the South West. So there we are, a tiny blue disc in our telescopes, and on the TV some mind blowing images of Neptune. I've only seen Pluto once via telescope, a 12.5" f6 Newt (superb optics btw). A dot amongst dots. So much looking forward to the flyby. Shame we don't have the delta V for orbit. |

KBO targets for New Horizons (other than Pluto and Charon, of course) found!

Question - would the major targeting for such an object be done post Pluto system flyby, or (more propellant efficient, but perhaps more disruptive?) by tweaking the flyby parameters for a gravity assisted course correction?

After the flyby. The science plan for the encounter is locked and loaded.

So, rough back-of-the-laptop calculation has a cruise time to KBO encounter of ~3.5 years. That's assuming constant speed, ~1 billion miles further to go. Here's to hoping a few more pop out of the woodwork!

Wonderful news and big congratulations to the team.
 Does 'definitely reachable' mean the target(s) can be approached arbitrarily closely? Can we look forward to seeing the selected one in as much detail as Pluto and Charon? EDIT: My question already answered by Emily http://www.planetary.org/blogs/emily-lakda...-has-a-kbo.html To summarise - Yes, close range is well within reach fuel-wise, but because the target's orbit will not be as accurately determined as Pluto's it will be harder to optimise the flyby distance perfectly for science. What would have been my next question is also answered. The definitely reachable target is a cold classical KBO. |

Terrific news! Congratulations to all the team for their indefatigable efforts in finding a candidate KBO.
I can't imagine that funding for a mission extension will be too hard to negotiate come the time A little early for image sequencing discussions perhaps, but assuming the object's orbit can be determined accurately enough, is NH capable of undertaking 'skeet-shoot' (as per Cassini at Enceladus) techniques for very close imaging, given the low-light levels and relative speed at closest approach? |
