I've come across some of the other Cassini recordings, as well as those from Galileo, Juno, Van Allen, and Voyager 1 & 2 probes as they explored Saturn, Jupiter, Neptune, Ganymede, and earths own [Van Allen Belt]. You can listen to the whole playlist of 46 recordings [here], below are a few of the highlights.
-Before entering orbit around Saturn in 2004, Cassini detected radio emissions on approach in 2002 which are related closely to the auroras of Saturn's poles, you can listen to them [here].
-Launched August 5, 2011, the [Juno Probe] entered orbit around Jupiter on July 5, 2016 to measure its composition, which will continue for another 5 years, 8 months, and 29 days. You can listen to some of its recordings so far of Jupiters auroras [here].
-The [Van Allen Probes] consist of two craft launched August 30 2012 to study earths Van Allen radiation belt, and are still currently active. They have recorded some rather unusual audio that researchers have nicknamed as "whistlers" or "chorus". You can listen to some examples of these [here] and [here].
-[Voyager 2] was launched August 20, 1977 to study the outer planets, Uranus, Saturn, Jupiter and Neptune. While its original mission ended on October 2, 1989 after it finished exploring Neptune, its currently on an extended mission to study the outer reaches of the solar system. Its been active now for almost 40 years and is still in contact through [NASA's Deep Space Network]. You can listen to the data its collected from Neptune [here], however there are a number of audio artifacts in the recordings, such as from Voyagers onboard power supply and other instruments.
-[Voyager 1] was launched September 5, 1977 to study the outer solar system, and was launched 16 days after Voyager 2. Like its twin it has been operating for almost 40 years and is the furthest man made object from earth, having crossed the Heliospause to study the interstellar medium. Its mission is set to continue until 2025, where its expected that its radioisotope thermoelectric generators won't be able to supply enough power to operate its scientific instruments any longer. You can listen to some of the data its collected from Jupiters noisy moon Io [here].
-[Galileo] entered orbit around Jupiter December 7, 1995 and was tasked with studying it and its moons, Europa, Callisto, and Ganymede. 14 years later on September 21, 2003 Galileo's mission was terminated and it was sent into Jupiters atmosphere to prevent the possibility of it contaminating any of Jupiters moons, a similar fate that Cassini shares. You can listen to some of its recordings of Ganymede [here].
