Signal received. Carried LOCK. Everything looks good and the spacecraft is healthy, reports Dr. Alice Bowman.

HUGE congratulations to the team and thanks for having has along.

CNDH reports expected amount of data collected.



Looking good. I wonder if Alice expected to be in the public spotlight so much.

I'm a bit overwhelmed. Cannot overstate congratulations to Alan and the entire New Horizons team. What an astonishing feat of technology and bold exploration!!!!

Absolutely, and they are going to be busy over the next 16 months. Can't wait to read the papers that come out of this epic project.

Big congratulations to the New Horizons team!

Now at last my attention can turn to looking forward to lots of hi-res images and other data in the coming days/months/year.

Interesting video of nitrogen freezing:

https://www.youtube.com/watch?v=c0rK2bLTimQ

Seems to have a somewhat violent behaviour at phase change - could be an agent in a weathering process.

See attached phase diagram for reference (it would be nice to see how it extends down to microbar pressures)

[attachment=36907:nitrogen.png]


Wow, no kidding, that phase change is surprisingly energetic.

The more I think about it, the more it seems unavoidable that at some points in time, liquids are going to be (present era) acting on Pluto. Not on the surface, but rather shallowly underneath it, shallow enough to have a visible impact on the surface. You stack enough ices of nitrogen, neon, or a number of other chemicals on Pluto, at Pluto temperatures, and they're going to melt on the bottom. Not kilometers deep - as little as a dozen meters worth for nitrogen at the right temperature (which at Pluto's low gravity isn't a lot of compressive weight). Unless there's not enough gases to freeze out that thick at locations where it tends to concentrate the most, it seems pretty much a given that it would happen. And even if it didn't freeze out that thick? You'd still get ground-liquids where it gets trapped in the ground's pore space, like we get groundwater on Earth.

Even liquid water on Pluto is not unlikely - although not near the surface:
