Science/Space geeks: ISS microgravity

Fine. Then I think it fluctuates every time Jer mashes the gas on his Tesla.

I'm trying not to say anything since I have no idea, but could those zero gravity experiments have taken place in a different area of the station that has less gravity? I assume (but don't know) that there is some sort of rotation to simulate gravity and anything toward the outside of the rotation would appear to have more gravity than the center. I'll have to watch the video later to see what the astronauts were doing while the globe was settling

Since anything that has mass also has gravity, I'd say we are all lending gravity to the situation.

I bet if you tweeted your question to Neil D Tyson he'd answer you.

Check the video I added to my reply above... you can see the tether if you look closely.

Yep. There's a tether.

The turbo-encabulator is out of calibration.....

Crap. Yes, you can see it laying across the handrest in front of it just before he gives it the second boot. Plus now that you mention it you can see the vector change just before it would hit the camera.

But still, it does seem to keep drifting "down" to the footrest area each time.

Nope, ISS has no rotation and no simulated gravity. Well, none to speak of since it does rotatate slowly in order to keep it's orientation to the Earth constant.

Any other drift/movement is most likely due to air currents, etc.
