boundary cognition from satellite images

Satellites are swapping around the Earth since 1957 - the launch of Sputnik. Already having a couple of thousands, the number is fast growing nowadays.


Just during the last week reading my rss, I got to know that China has launched Yaogan XII, Vietnam is buying Japanese satellites, Turkish  recently launched satellite RASAT is already transmitting images, Russia is about to launch 4 more GLONASS satellites to existing 28 ones, and so on an so on.. Europe, yes Europe as well, finally launched 2 GALILEO satellites last month. Future, talking about the number of satellites, is amazing..
I am glad we still can see the sky over them.
