A satellite is like a hundred miles up. It is possible to make lenses that can give a usable image at that distance, but they are not wasted on people who only want to find a chick sunbathing in the yard. Also, a satellite is moving about 18,000 miles an hour, so you wouldn't have enough time to pick out any particular motion down below. You only get 1 2/3 minutes over each TIME ZONE!
Thank you
