New Horizon's distance from Pluto drops below 500 million km today. The main thread here has been active since before launch and until today.

Today is an appropriate day for a new thread and there are also less than 14 months until Pluto arrival (time flies!). The coming months will see more spacecraft activity than in recent years with optical navigation images of Pluto/Charon, images of Neptune etc.

The next 14 months are going to be interesting to say the least.

Interesting is an understatement. This is going to be a fun year. To think, in July 2015 we'll be the first humans to ever see Pluto.

Yes, and to think, 2014 is the last year when no one knows what Pluto and it's satellites really look like.

Mr. Stern, I would like to thank you so much for New Horizons. What you and your team have done and are doing, it's a privilege to see what amazing will come of this.

Thank you,
James Sontag

Thank you James, it's an honor for all of us on New Horizons to make this science exploration dream come true.

A question on behalf of Alan: New Horizons accomplished a trajectory correction maneuver yesterday. Someone on Twitter suggested this was the deepest-space-ever rocket burn. Is it? When/where was the last Voyager TCM?

Nice piece on our optical navigation plans, written by Emily following last week's science team mtg: http://www.planetary.org/blogs/emily-lakda...v-campaign.html

Which reminds me, I got an answer to my question above from Twitter: The last TCMs of the Voyagers:

Voyager 1 = 1980-312/04:24 GMT after Saturn Flyby
Voyager 2 = 1989-233/15:14 GMT after Neptune Flyby

Emily- These are great numbers to have, thanks. One note, DOY=233=21 Aug so I believe the last Vgr 2 burn was just *prior* to Neptune C/A. Didn't ck on the Saturn DOY...

It's a very busy little system down to the limit of Hubble resolution, I'd be quite surprised if there aren't a number of other chunks of debris to add into the mix as these opnav campaigns proceed. Any redundancy in the obs campaign for as-yet unresolved moons/rings???
