Interstellar snail mail

Late 2007 sees the launch of Keo. What makes Keo unusual is that it is effectively a very slow, very expensive, postal delivery system capable of carrying six billion letters. Not only that, the delivery destination is the same place it is departing from, and it will circle its destination for thousands of years before actually delivering any mail.

So what is the point. Well this is where it gets really interesting and worth a little bit of your time, because Keo is a satellite which is to return to the earth 50,000 years from now and deliver those six billion messages to our descendants. And to make sure they see it coming, it is equipped with a special thermal shield which will create an ionization phenomenon similar to the Northern Lights on re-entry. It will orbit the earth at an altitude of 1,400km in a circular orbit of less than 57 degrees in an effort to try and reach the 50,000 year goal while sustaining the radiation and resisting debris impact.

Visit the site and leave your message of no more than 6000 words. You must also provide some additional information and answer some questions. They also are trying to assemble a contemporary library of Alexandria and are collecting other documents and information. A great project for schools too.
