So yesterday I got a tour of the factory floor of SpaceX. We saw their powerful new rocket engine, four of the five Dragon modules (one already used and on display, three others in various states of construction), one of the coolest 3D printers I've ever seen, and sat in a prototype dragon module that could carry passengers.

One of my favorite memories was watching people walking around carrying bits of spaceship.

I was grinning so much my face hurts today.

Sorry, no pictures were taken of course - they don't want their trade secrets to leak out. But WOW.
