Heh. My 4 are still flying nicely. I do have one or two pop in at a very high speed from outside the range of the screen now and then, but it's a pretty rare occurance.

Interestingly enough... I have finally managed to get one sattelite going in a stable counterclockwise orbit. I didn't think it possible before now... All my others crashed... This one is actually in a pretty high orbit too, which is surprising, as the moon has a very damaging effect to the orbits of the ones in counterclockwise patterns.
Bah... it just crashed... but I do have another in a very low orbit that seems to be doing fine.
