Listen to the eerie sound of a boom on board ESA’s Jupiter Icy Moons Explorer (Juice) spacecraft deploying in space during commissioning of the spacecraft in May 2023.

 

Tip: use headphones or surround speakers for the best experience – the forward and backward wobbles of the boom come through the left and right channels.

 

The vibration signal used to create the sound came from the accelerometer on board the main body of the spacecraft, which was switched on to monitor the reaction of the spacecraft to the boom’s deployment.

 

The larger the vibration measured by the accelerometer, the louder the sound in the sonification. We can imagine the boom like a human arm initially folded into the body; the first higher-pitched ‘ring’ that you hear is the elbow opening and the second lower-pitched ring is the shoulder stretching up.

 

Though the accelerometer measurements were not mandatory to validate the deployment, the engineers working on Juice were happy to see that they are very accurate. Turning the vibration signal into sound may help us understand the mechanics of the deployment.

 

The boom is one of four 'Langmuir probes' that are part of Juice's Radio & Plasma Wave Investigation experiment. These probes will provide crucial information on the electric fields and plasma environment around Jupiter's moons.

 

The sonification was prepared by Johannes Z. D. Mieth (TU Braunschweig) and Willi Exner (ESA).

What meeans "ⓁichtⒷildⒼestalter" ? 
Could be translated as  >>LightPictureDesigner<<
In the past, a photographer was also called a light-image designer (LichtBildGestalter in german).

All tunes I publish here are free works and non-commercial!
I returned after the hearing loss (deaf in the right ear) and a long abstinence to electronic music in 2014/16.
While I used to make music exclusively on hardware synthesizers in my early days, a number of virtual instruments are now in use. My DAW is Ableton Live with a lot of Plugins ;-)
For many years, I have only been able to hear on one hearing. This makes it difficult for me to mix them but I give my best.
Besides music, photography is my great passion, that's also where my artist name comes from. Therefore all pictures and photos that can be seen on Sondcloud are my own work.
Enjoy the music, the pictures and have fun!
