A simple sonification of the variability of the total magnetic field during BepiColombo’s second Venus flyby as measured by the Mercury Planetary Orbiter’s Magnetometer (OB sensor). 

The audio spans the same time range 12:00 to 14:30 UTC on 10 August 2021, including the closest approach at 13:51 UTC. 

Almost all high frequency noises are due to spacecraft activity. The low frequency, wind-like noises are caused by the solar wind and its interaction with Venus. The sudden bow shock crossing towards the end can be heard clearly. The data is not yet cleaned from high pitch spacecraft disturbances, but the wind-like sounds allow a rare glimpse into the solar wind interaction with a planetary atmosphere.

What is heard is the 128 Hz measurement of the high-pass filtered (0.01 Hz) total magnetic field, mapped to audio with 44.1 kHz sampling frequency. For better audibility some compression, limiting and increase in gain is applied to the signal.

5. SHALLOW - DEEP

We go about our daily lives without giving it much thought. In the morning, we wake up to the alarm on our smartphones, turn on the tap, wash our faces with the water that comes out, and brush our teeth. We eat breakfast heated in the microwave, oven, or on the stove, and then we take the train or drive to work or school.

If we don't pay attention, the day goes by without us feeling anything special. But this is not the norm. We are just standing on top of the layers of history that our predecessors have gradually accumulated through their wisdom and effort. And we are only part of the layer that the next generation and the generation after that will stand on.

This work imitates the accumulation of such invisible history in sound. The sounds don't build up, just five mundane five-minute drones, but if you pay attention, you'll notice that they change little by little. I believe that to observe this is to see the invisible history and to get to the essence of things.

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).
