Re: John W. - falling satellites . . .

A geostationary satellite maintains its position over the same spot on the equator because it is orbiting in the same direction as the Earth's rotation, and at the proper altitude (35,786KM)and speed to match the Earth's rotation.

In a polar orbit, no matter what the altitude or orbital speed, the Earth's rotation is at right angles to the orbital plane, so the Earths surface will pass beneath the sat at a 90 degrees angle to the direction of the satellites motion. It won't "fall to the Earth", but it can't possibly stay over the same spot on the Earth's surface either.
