Project Calliope - Music and MIDI Signals From Space

"'Project Calliope' is a satellite being launched by a group of space & music enthusiasts on the "TubeSat" platform (http://tinyurl.com/skycall). It'll be an ionospheric detector transmitting sonifiable data back to Earth for web streaming and remixing. Conceptually, it's a musical instrument in space, played by space rather than just after-the-fact sonified. We like the idea of flying something in space whose purpose is to make music until it dies-- music from science."

via the Satelite Diaries blog:
"The instrument-- a MIDI keyboard, MIDI drum, MIDI saxophone, MIDI satellite-- generates event messages that you can feed into a sound card or synthesizer. It's kind of like transmitting a player piano roll, it has no sound itself, but it lets other devices create sound."
