I've been wondering, since you can see Iridium satellites flaring in broad daylight, why couldn't astronauts on board the ISS see flashes from a person holding up a mirror? The antennas on Iridium satellites are only about the size of a door. If you had a mirror about that size, and the astronauts were informed of when and where to look, I bet they could see it. That would be something cool to try out if it was possible to inform them...
