Cosmoknowledge - Location of Voyager spacecraft.

August 20, 1977 - Voyager 2 Launch This sonification (the practice of turning data into sound) maps the speed of the Voyager 2 spacecraft as it moves throughout the solar system on the Grand Tour, picking up gravity assists from Jupiter, Saturn, and Uranus as it passed by. The speed ranges from about 40 km/s to 10 km/s over the 10 year period shown. Those values have been mapped to a C Major scale and rendered as scaled notes over the keyboard range. You can hear its speed slowly decreasing as t
