The Last Pictures by Trevor Paglen — an ultra-archival disc of images capable of lasting in space for billions of years:

In 1963 NASA launched the first communications satellite “Syncom 2″ into a geosynchronous orbit over the Atlantic Ocean. Since then, humans have slowly and methodically added to this space-based communications infrastructure. Currently, more than 800 spacecraft in geosynchronous orbit form a man-made ring of satellites around Earth at an altitude of 36,000 kilometers. Most of these spacecraft powered down long ago, yet continue to float aimlessly around the planet. Geostationary satellites are so far from earth that their orbits never decay. The dead spacecraft in orbit have become a permanent fixture around Earth, not unlike the rings of Saturn. They will be the longest-lasting artifacts of human civilization, quietly floating through space long after every trace of humanity has disappeared from the planet’s surface.

Commissioned and presented by public art organization Creative Time, The Last Pictures is a project to mark one of these spacecraft with a record of our historical moment. For nearly five years, artist Trevor Paglen interviewed scientists, artists, anthropologists, and philosophers to consider what such a cultural mark should be. As an artist in residence at MIT, he worked with materials scientists to develop an ultra-archival disc of images, capable of lasting in space for billions of years.

In September 2012, the television satellite EchoStar XVI will lift off from Kazakhstan with the disc attached to its anti-earth deck, enter a geostationary orbit, and proceed to broadcast over ten trillion images over its fifteen-year lifetime. When it nears the end of its useful life, EchoStar XVI will use the last of its fuel to enter a slightly higher “graveyard orbit,” where it will power down and die. While EchoStar XVI’s broadcast images are destined to be as fleeting as the light-speed radio waves they travel on, The Last Pictures will continue to slowly circle Earth until the Earth itself is no more.
