KEO is a time capsule that will be launched into space and return in 50,000 years

KEO is a time capsule that will be launched into space and return in 50,000 years! which has enough space for everyone on the planet to submit a 4 page letter about themselves, it’s completely uncensored and free.

KEO is the name of a proposed space time capsule which was to have been launched in 2003 carrying messages from the citizens of present Earth to humanity 50,000 years from now, when it would re-enter Earth’s atmosphere. It was later delayed to 2006, then to 2007/2008, then to 2010/2011, then to 2012, then to 2013 and is currently estimated to launch in 2015.

The project KEO claims to be supported by UNESCO (who it claims voted it “Project of the 21st century”), Hutchison Whampoa, the European Space Agency, and among other institutions. Its name represents the three most frequently used sounds common to the most widely spoken languages today, /k/, /e/, and /o/

Every person is invited to contribute to the time capsule. The contribution deadline was originally 31 December 2009, but as of 2014, it has been extended to end of 2014. Messages can be posted via the project’s website or sent by postal mail.

The organizers encourage everybody to gather messages from children, senior citizens, and the illiterate so that every culture and demographic on Earth is represented. The organization says, “All the messages received, without undergoing any censorship, will be embarked aboard KEO.”

The satellite has enough capacity to carry a four-page message from each of the more than six billion (as of the original 2009 deadline) inhabitants on the planet.  Once the satellite is launched, the messages will be made freely available on the web.

Other contents

KEO, a space time capsule, will also carry a diamond that encases a drop of human blood chosen at random and samples of air, sea water, and earth.[5] The DNA of the human genome will be engraved on one of the diamond’s facets. The satellite will also carry an astronomical clock that shows the current rotation rates of several pulsars, photographs of people of all cultures, and “the contemporary Library of Alexandria”, an encyclopaedic compendium of current human knowledge.
