In 1997 the Cassini-Huygens spacecraft was launched from Cape Canaveral, its primary objective being the study of Saturn’s geology. As the spacecraft neared Saturn in 2002 it began to detect intense radio waves from the planet’s polar auroras. This sound piece modifies some of the recordings made by the Cassini-Huygens spacecraft.
In order of their appearance the sounds include: solar oscillations, radio emissions from Saturn, waves of light from Kepler’s Supernova, comet dust hitting the craft, Saturn’s rotation, a rocket launch.
