Denton (@spacewhalerider.com ) points out that Pluto-Charon are similar to the Earth-moon system, in terms of both size and angular momentum. Earth-moon formed via impact.

It's Friday, and that means a half day at #Pluto10

Which is good.

In completely unrelated news, I will be sleeping extremely late tomorrow, in my very comfortable bed.

Alan Stern & Orkan Umurhan—there are unusual dark streaks and swirls in the northern part of Sputnik Planitia (the giant nitrogen-ice glacier that makes up part of Pluto’s heart). They propose that this is the consequence of melt (liquid nitrogen) rising from the base of the glacier! #Pluto10
A photograph of a sketch in my notebook where I summarize a talk by Alan Stern and Orkan Umurhan. on the left is a sketch of Pluto centered on Sputnik Planitia. I highlight the northern part of Sputnik Benicia, where there are some darkened streaks amongst the convective swirls of the glacier. On the right hand side of the sketch, I zoom in to a cross-section of this portion of the glacier. In the side profile, you can see a thick, nitrogen ice glacier, shown mostly in grays, overlying a water-rich icy crust, shown in red. They hypothesis that the bottom of the glacier is melting, producing effectively liquid nitrogen. Unlike basal melt in a terrestrial glacier (water) which stays confined to the bottom of the glacier, basal melt in a nitrogen ice glacier would be buoyant and rise through the glacier to the surface. I show that here with some blue coloring: I show a layer of blue at the bottom of the glacier, and then a upwelling that goes towards the surface. At the surface of the cross-section, I show the surface of Sputnik, including a convective cell that is bordered by a trough. The upwelling melt reaches the surface first at the trough, fills in the topographic low, and darken it. in a text box to the side, I explain their hypothesis. They believe that this region of Sputnik is sublimating away. As the glacier thins, it reduces stress on the ice, promoting the growth of larger grain sizes. Larger green sizes, inhibit convection, and make it harder for the glacier to lose heat. Thus the bottom of the glacier can get warmer and melt.

10 years ago, the New Horizons mission flew past Pluto. That world, that mission, and the team of people that made it happen—changed my life.

Last week was the #Pluto10 workshop. It was amazing to see all of the continuing science from Pluto!
A photograph of a sketch in my notebook, done for the T +10 years Pluto workshop that was held last week at APL. The sketch shows the number 10 drawn out in a very modern font. At the top of the one is the new horizon spacecraft, glistening in gold. The number one is almost a trail left behind the spacecraft, drawn in a blue gradient. Inside of the zero is a sketch of Pluto itself, centered on the encounter hemisphere, and Sputnik Planitia. Pluto is in shades of red, brown, yellow, and gray. Beneath the large number 10 is the title of the conference, “progress and understanding the Pluto system: 10 years after flyby.“ I’ve also drawn some colorful rainbow “swooshes” behind the graphics. The entire drawing is maybe 6 inches across, as you can see the pen just next to the notebook for scale.
