BepiColombo explored through sound
What does a spacecraft mission sound like when the data comes first?
ESA’s Expedition Sound Episode 2 follows BepiColombo, the ESA/JAXA mission travelling towards Mercury, through the people who turn scientific measurements into sound. I like this framing because sonification is not a microphone recording from space. It is a deliberate translation of data: patterns in fields, particles, or spacecraft systems mapped into audible changes.
Listening without mistaking sound for noise That distinction matters. The result can be evocative, but its value depends on what was measured, how it was scaled, and what the listener is meant to notice. A good sonification makes structure easier to examine without pretending that Mercury is literally broadcasting a soundtrack.
The episode is part of ESA’s official Expedition Sound podcast series, which explores missions through scientists, astronomers, and sonification specialists. For anyone interested in the boundary between instruments and interpretation, this is a more useful listen than the usual dramatic space montage.
