The sound of the solar wind at Venus by European Space Agency published on 2021-08-13T09:59:39Z 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.
