Yes! Goosebumps.. But, I must unfortunately confess.. seeing all that unbranded space on the Dragon had me cynically thinking, how much could they sell that ad space for?

You know... Someday someone will put a Pan-Am logo there...

How hard would it be to procure the rights?

I've been waiting for this for a long time. I spent the past two summers working on the Dragon docking as an intern.

Are you a programmer? Is the docing full automatic? Until know the only automatic thing was the ATV right?

I'm an electrical engineering student. When it came to docking mechanism I was an embedded systems programmer. Yes, to my knowledge the docking is fully automatic.

Question: if Dragon is about 200m lower than ISS, and they are moving at the same velocity at one instant, wouldn't that put them in different orbits? Assuming ISS's orbit was perfectly circular, then Dragon would be moving too slow for its lower orbit, and would sink down, to its perihelion when on the opposite side of the earth, and so on, oscillating up and down, in an elliptical orbit with respect to ISS. The onl…

At some point when they were a few meters away, the NASA video mentioned the Dragon was now "free floating". So, I think they were continuously gently firing the thrusters to maintain orbit until they got extremely close.

Many things would have to happen to make it possible:

- SpaceX would have to want to sell the ad space.

- If NASA is paying for the mission, they may want to have a word (most likely "no").

- The owners of the Pan-Am brand would probably appreciate the gift, but I'd like to make sure they won't get mad before any such stunt.

- The Arthur C. Clarke and Stanley Kubrick estates would also have something to say, after all, this is more or less a reference to 2001.

Tell us more! Blog link about it?

Well I spent the last two summers as an intern at SpaceX working on several things, but one was that mechanism that the Canadian arm attaches to. I can't talk much about the specifics, but one of things I did was program the micro-controllers that interface with the motors that open the hatch door (and some other stuff) that contains the hook for the robotic arm to grab. I wish I could write more and even make a blog post, but I'm simply not allowed to do so.

I'm kind of surprised that SpaceX didn't consider that for the outside of the dragon capsule.

Note that the capsule has a camera inside of it (there are pictures from it on SpaceX's site) so when the hatch opens you can see pictures directly from a video camera that isn't under NASA's control.

NASA is broadcasting: http://www.nasa.gov/multimedia/nasatv/ustream.html Anyone know what time it's expected to dock at?

What are the tiny objects that seemed to be criss-crossing all over the background of the blinking light (visible clearly in fullscreen) ? Other satellites?

either a city or another satellite. The first "mysterious light" I saw, which I thought was another lit satellite, was eventually described by the channel narrator as the city of Los Angeles going by far below. It was late at night, and we were seeing the lights from the LA metro area.

Watching the Dragon approach from the point of view of the ISS is incredibly exciting in itself, but almost unbelievable when you think about the speeds they are flying at relative to the ground!

What's unbelievable about this? If I approach you on the ground we are both moving fast relative to center of the Earth. Or imagine us onboard the airplane.

It would be unbelievable if you approached me from the center of the earth, if you want to keep the same analogy :)

There was a moment when the Dragon had a speed of 0 in that frame of reference, what's unbelievable is the complexity of catching up to the ISS!
