Sonic Planetarium is an audio model of the stuff in Earth’s orbit, in real time. Visitors to the dome-like installation hear sounds from all directions representing orbiting satellites within range of the installation's location. Sounds matched to individual satellites play directionally across the speaker array, tracking the actual objects as they pass far overhead, as if you can hear into space. The character of the sounds, which are recordings of satellite transmissions, morphs every few minutes, and the combination of sounds is as
unique as the combination of satellites within range.
