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).

Sound of a Juice boom deploying

This episode marks Kiersten’s last astro[sound]bites episode (and also side note – we’re posting this on her birthday!). To recognize Kiersten for her incredible time as a co-host, we take a journey through her academic paper trail by discussing her papers on how magma and metallicities affect how we think about exoplanetary formation and observations. Then we take a deep dive into Kiersten’s time as a co-host and graduate student including her stance on “publish or perish” and what she’s most excited about starting her NASA Sagan Postdoctoral Fellowship this fall.

Episode 96: kiErsten’s Exoplanetary Elemental Exit Episode

Astrobites turns 100! For our ten squared-th episode we take a tour of all of the extremes of astrophysics: the heaviest and the lightest, the fastest and the slowest, the brightest and dimmest. In doing so, Shashank covers an astrobite on itty bitty particles that pack a big punch, Lucia talks about medium-ish galaxies and their black hole hearts, and Cormac panics about the danger of violent kilonovae. To help us celebrate, we meet up with some old friends to discuss dark matter, exoplanets, and how ridiculously long a Ph.D. takes.
