I track satellites and space junk for a living, I work with optical telescopes. The way it works is, the telescopes only sees light reflected off the
object, not the actual object, and the computer figures out what it is, based on how the light (the sun) is reflected off it. So, you could see a
silver wrench floating in space, but not a semi truck painted black (well, optical sites anyway). We only operate at night, and can only see certain
objects, based on it's sun angle.
My point being, satellites are made to be pretty darn reflective!
