Pluto today (left, via New Horizons) and from a painting done in 1979 (right).
I talk a lot about how entwined art and science are, but I don't think I've ever seen as good an example as this: Space Artist Don Dixon predicted what Pluto looked like back in 1979 ... and he nailed it. Are you kidding me? That's the cover he did...Read more from Slate Magazine
To me, the craters look like the impacts were made in a very dusty environment. But I am mere amateur so...
I don't think the craters would still be so well-defined if it were dusty, would they?

Take a pile of flour. Put it in a layer, not real thick. Drop something in it. To me it leaves the same type of cratering as seen on Charon.
True, but left on its own, or with any wind, and the sides collapse and soften.
I've been expecting-and seeing-amazing images of Pluto from the close approach flyby of the New Horizons probe from mid-July. And even though I knew the images taken once the spacecraft was past Pluto would be lovely, I still wasn't quite prepared for just how awe-inspiring they would be.

"True, but left on its own, or with any wind, and the sides collapse and soften."
Much less gravity and I doubt Charon has any wind to speak of.
Can you say "bullshit" at NASA? The principal investigator for NASA's New Horizons mission did, in an outburst directed at the tortuous rules that led to Pluto's reclassification as a dwarf planet. "It's bullshit," Alan Stern, a planetary scientist at the Southwest Research Institute, told Tech Insider - with the clear intent of being quoted.Read more from GeekWire
How's that for a milestone: Pluto is now in Google Earth (er...Google Pluto?). http://t.co/QvgK6axdZy HT @skdh pic.twitter.com/qgxAC93RvW— Corey S. Powell (@coreyspowell) July 31, 2015
