Q&A: Why the ISS Doesn't Rotate and More...

Hey, Fraser! I enjoyed your appearance on TMRO. Keep up the awesome work. As far as ISS not rotating, it seems like microgravity is what gives the ISS its worth as a laboratory. Artificial gravity will be great for many future space stations, but sometimes the magic of falling for a few decades straight is kinda the point, right? :)

Is it not orbital velocity?

I don't know if this question is even worth answering, Frazer, but if Skylab was Space 101, would you call the ISS Space 102, Space 201, or something else altogether?

Frazer, wouldn't it be possible to "see" a black hole that doesn't have an accretion disk around it by observing the way light from distant objects bends around it? The larger the black hole, the easier it would be to "see"???
