I'll take you all's word for it.. I was pondering it as you
would a matchbox car rolling across a globe.. ??
If it's rolling, it must be real slow about it, as it's not
really detectable on the cameras.

Take an experiment. Go to your dining room table, opposite the door to
the kitchen. Face the table (and the kitchen door).

Now, walk around the table, trying to keep facing the table without
rotating your body. You can't do it.

The ISS is the same. You don't see the rotation because the ISS is
stationary (rotation-wise) relative to the earth, and you are observing
the earth. But if the cameras were pointed into space, you would see
the stars move as the ISS rotates.

The moon is the same way. It makes a complete rotation once every
orbit, thereby keeping the same face pointed at the earth.
