KEO is a satellite built to return to Earth 50 000 years from today. It shall bring back to our far away descendants every message that each and every one of us is invited to put on board.
Every person living on Earth, small, weak, powerful or rich is provided with 4 pages of liberty and equality to pen down his message destined for his faraway great grandchildren.
All the messages received, without undergoing any censorship, will be embarked aboard KEO.
