Just as you say that an object accelerates to the ground, the camera does the same thing in ISS. There is no way of telling the difference between a gravitational force field, and an accelerating reference system! Thus, there does not excist any reference system that is more true than any other! You simply select the most convinent one for you needs. In this case the ISS. Also, you should remember that the ISS is in free-fall towards the earth, i.e. ISS is always accelerating.

In this case, you are the observer in the video--> the camera is accelerating in *your* frame of reference. There *is* a force on the camera--gravity. From the earth's frame of reference, the camera is already whizzing around the earth at great acceleration; the difference in acceleration between the space station and camera is minor in comparison.

I really wonder why they just don't have a camera on an intervalometer constantly shooting landmass as it orbits. Sure there's satellites that do it better, but the ISS wouldn't really cost anything and provide more general imagery. Good find.

Or did Nikon pay him for the "free" ad :)? Nice they can just attach it to the wall w/o much effort, that's what, a 7Kg kit?

They all have PhDs, they have all have published extensively in computer science fields. When I go to conferences I see a fair share then also, but to be honest fewer because most have laptops provided by their employers and in that case it tends to be windows machines. In academia, though, we usually have the choice to buy the machine that we want and a lot of the time it's running os x. Anyway, not worth arguing over. I just wanted to point out the mis-perception that professional users just come from video/photo fields. I enjoy using my mac for work though personally I dislike apple and their locked-in business model (and their crazy key bindings). Roughly half the people I work with use apple laptops.

The other two cameras are at the right side with a 300-800 attached to a D3 series body (note the large bulky pentaprism part) and our D2 series with 800mm f5.6 (2x + 400mm) attached.. The lenses are not VR and are not ED II series. I have a ED II 300mm f2.8, this one and all other ED II series has golden nameplate on them like old 70-200 VR or 200mm f2 VR. These lenses has black nameplate like AF-I and AF-S ED. I am not sure which of it but i am sure that lens has internal motor due to the buttons on it..

However, at launch the Canons got shaken into jumbo mess of parts inside the bodies. The big honcho gave the contract to Nikon and never looked back. The rocketscientists Canon fanboys tape white canvas all over them. From what I understand, NASA did try Canon because the lenses color match with their vehicles and spacesuits so well.
