Pretty decent resolution of a object 27000 km distant. Has anybody seen the specs on what type of lens NH uses for images like this?

This is still nowhere near full resolution - it's at 140 meters per pixel, whereas the camera got 30 meters per pixel. It's going to take a few days to download the full images at 1kbps though.

That is amazing. It reminds me of a snowman or two snowballs frozen together, except it's red not white. As seen in the combined image. http://pluto.jhuapl.edu/Galleries/Featured-Images/pics800wid...

Comet 67P has a similar shape. I have to wonder if there's something inherent in these flying rocks that causes them to take a dumbbell shape.

The inherent factor is collision, which is what forms most objects like this.

I find it more impressive and awe inspiring that stuff in space is so predictable that we can actually program the fly by such a long time in advance and get such a high degree of accuracy.

have you ever done course corrections in KSP? A tiny nudge early on is enough to make a huge difference farther out!

Yup. And if you've ever done maneuvers manually in KSP, you know that a tiny error in your nudge early on - e.g. hamfisting the throttle, or being a little too late in mid-maneuver staging - leads to a huge difference farther out, which you then have to correct, wasting precious ∆v :).

I'm very much impressed by the control precision of real-life space probes.

Huh, given the color photo, it reminded me of a potato. Yes, I really did find a potato looking like this once.

ah yes, you are commenting on the precision not on the magnitude of the displacement!

I think everyone with an interest in spaceflight should play Kerbal Space Program. It gives you a sense of scale, both of space and time (luckily you can fast-forward to 100.000x), and also teaches you the basics of making orbital trajectories and correcting them, landing on planets/moons with different gravity... I'm really glad to have played it!
