Kay well first of all, this project has been going on for quite a many years so I apologize if its a repost.
About KEO - http://en.wikipedia.org/wiki/KEO
Basically, they're sending a timecapsel to the space that will, if all goes well, return in 50000 years or so and every human being right now has a chance to send a letter with it to the outer space, for the future generations to read. Kinda like what cave paintings were for us, so future people (if the human race will survive for another 50000 years) can read what we, the simple people from year 2006-2013 have written in there.

Seems quite interesting to me, gotta think what to write.

The messages and library will be encoded in glass-made radiation-resistant DVDs. Symbolic instructions in several formats will show the future finders how to build a DVD reader.
The satellite itself is a hollow sphere 80 cm in diameter. The sphere is engraved with a map of Earth and surrounded by an aluminium layer, a thermal layer and several layers of titanium and other heavy materials intertwined with vacuum. The sphere is resistant to cosmic radiation, atmosphere re-entry, space junk impacts, etc. For its first few years in orbit, KEO will sport a pair of wings 10 meters across that will aid in its spotting from Earth. As the satellite enters the atmosphere, the thermal layer will produce an artificial aurora to give a signal of the satellite's re-entry. The passive satellite will not carry any communications or propulsion systems. It will be launched by an Ariane 5 rocket into an orbit 1,800 km high, an altitude that will bring it back to Earth in 500 centuries, the same amount of time that has elapsed since early humans started to draw in cavern walls.
