The SETI Institute is ready to take music to Mars, or wherever. While it’s a listening project, it’s also now a beaming project. A founding astrophysicist and a musician “have devised the ‘Earthling Project’: a call to people everywhere to upload snippets of song that [the musician] plans to meld into a collective human chorus. An initial composition will be launched into space this summer, inscribed on a virtually indestructible disk alongside Wikipedia and the Rosetta Project, a sampling of 1,500 human languages. Future plans and dreams include an eventual dispatch to Mars.” – The Economist
