Bepi Colombo Flies Over Earth: Writing “The Sound of the Universe”

According tomedia reports, the European Space Agency (ESA) has released a “sonic map” of telemetry sent back by the BepiColombo Mercury probe as it flew over Earth on April 20, 2020. Sounds like a series of intones, and the five pieces of audio were captured by two instruments mounted on two connected orbiters during the European/Japanese Deep Space Mission.

During the April flyby, some instruments on JAXA’s Mercury Magnetospheric orbiter were able to calibrate them before reaching Mercury. These include the Italian spring accelerometer , which measures the speed changes of the detector in several directions and the MPO magnetometer — to measure the magnetic field of the detector as it flies.

Each data record is converted to audio and adjusted to the human hearing range. In addition, you can time up to 8 hours to compress audio to one minute or less.

When BepiColombo approaches Mercury from an altitude of 256, 39 to 129,488 km, its sonic detection data includes accelerometer data, which passes through another audio orbit at an altitude of 12,689 km, and a third audio orbit as it passes through the Earth’s shadow. At the same time, the MPO magnetometer Bepi Colombo sent back data as it passed through the shock waves of the Earth’s magnetosphere. The fifth recording is based on the same magnetometer reading.
