Great work Roman!

Here are some treatments I made with the data released this week.

Great work Roman!

Good job Sean! Thank you!

I remember someone on a NASA website (might have been Mrs. Lakadawa but don't quote me on this) promising that true color, high resolution photos of Pluto will eventually be released? Have they been? I am not talking about that day 1 release image, but really high res. But I have only seen amateur colorizations so far. I had hope until the transmissions from NH have been announced to be finished but still no true color, high resolution photos! Have I missed anything?

The highest-resolution color image was publicly released as soon as it was received, here. However, this was enhanced color, showing more color detail than the human eye would see. If you're asking about "true color" as the human eye would see it, we might not have released a version of that image that's true color, though we've released low-resolution true-color images (e.g. here). Perhaps someone on this forum has made something closer to a true-color version of the highest res color image?

I remember the promise was about a high resolution, true color image. It was after those false color high resolution pics were released.

I didn't find the blog post but I found this post by Mrs. Lakadawa here http://www.unmannedspaceflight.com/index.p...st&p=227260 , I don't want to be demanding, but I would like to ask if those "true colorish" official MVIC pictures have been released. Thanks in advance.

A work in progress restoration of P_PHOTSLEW. I've been working this off and on for about almost two years, but after seeing Roman's fine version I figured I might as well put mine out there (I added a color overlay too).

[JRehling]

Great work, Ted, Roman, and all. The sustained feeling of amazement occurs with each post, and shouldn't go uncommented. It still feels like someone invented Pluto with the specific goal of making it amazing.

I'll photograph Pluto in the coming months and it will be a dot, but your images will make it a place.

I do not know if this is the right place. I watched this Pluto area. What is these like rivers?
nitrogen ice flows?

Sputnik planum could be in the past an exposed ocean of liquid Nitrogen as is the case with Titan's methane oceans?
can a planet or dwarf planet exist with an exposed ocean of liquid nitrogen?
how big must a planet be to have a liquid nitrogen ocean??

Back in 2011, there was a suggestion that rivers of liquid nitrogen might be stable on Pluto
http://www.planetary.org/blogs/emily-lakda.../2011/3182.html

That was followed up by 2016 announcements that when Pluto's orbit and rotation are just right,
Pluto's atmosphere should support an atmosphere thick enough for liquid nitrogen to flow.

“The pressure changes radically,” says New Horizons principal investigator Alan Stern. Today, he says, Pluto’s atmospheric pressure is “atypically low,” noting that at maximum it can be more than 20,000 times the current reading.



That means surface temperatures must be fluctuating enough to mess with the nitrogen on Pluto’s surface, driving it from a frozen solid into a gas. And sometimes, the temperature and pressure occasionally rise high enough for liquid nitrogen to flow on the surface.

The last time temperatures were sufficiently high to melt nitrogen was around 800,000 years ago, when Pluto’s orbital alignment led to its most extreme warm climate, says MIT’s Richard Binzel.

Question about possible transient atmospheres on Pluto (and perhaps Ceres): Assuming there is a sufficiently robust outgassing event occurring in the current or past climatic conditions, what is the highest possible temporary atmospheric density/pressure? And how long would it take to return to normal, assuming the outgassing ceased?

Our paper sets a limit near a few hundred millibars for Pluto.
