Project Calliope is an upcoming orbiting satellite that will convert Earth's ionosphere to music for people to share. Calliope lets people get a sense of how active space is. Calliope will measure the ionosphere for its 12-week life and transmit that data as sonified MIDI data (akin to sheet music) so anyone with a ham radio or web connection can listen to it-- or remix it into their own music compositions. It is planned to launch into orbit in late 2011.
