Scientists first recorded the sound of wind near Venus

Scientists translated the data from Venus into sounds – so they were able to determine how the flow of charged particles interacts with devices around. Now you can listen to them in the public domain.

The BepiColombo spacecraft, orbiting Mercury, recorded the sound of the solar wind on Venus as it flew just 550 km above the planet’s surface during a maneuver aimed at correcting its trajectory.

BepiColombo, a joint mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA), recorded sound with a magnetometric instrument, providing a rare insight into the interaction between the flow of charged particles flying from the Sun, i.e. the solar wind, and the dense the atmosphere of the closest neighbor of the Earth, rich in carbon dioxide.

Audio recording is not real sound that can be heard in space, but the so-called sonification, the translation of data into sounds, the ESA said in a statement.

BepiColombo flew past Venus on August 10, just a day after another inner solar system explorer, Solar Orbiter, made its close approach to the space object. This allowed scientists to measure the environment around Venus from multiple points for the first time.

The Solar Orbiter, a joint ESA / NASA mission, has a magnetometer similar to the BepiColombo in its instrument kit. He made his own measurements of the interaction between the solar wind and the planet, flying on August 9 at a distance of 8 thousand km.

Researchers have published several versions of the sounds. The first is the onboard accelerometer data translated into audio recording. Another version is the sonification of the magnetometer data. It demonstrates the process of interaction of the solar wind with the planet’s atmosphere.
