}Also, the U.S. monitors space junk probably much smaller than 1 inch.

}or whathaveyou.
I am inclined to believe that this detection is based on the ability
to differentiate the object from its background (i.e. none). An object
against the ground would probably be much harder unless there was some
characteristic which enabled easy separation.
