Sounds heard by scientists as Mercury-bound Bepi-Colombo passed our planet

According to a report released on 5 May by European Space Agency, Bepi-Colombo stored five eerie sound recordings as it soared past our world at a speed of 2.159 miles.

The flyby operation of European-Japanese that took place on 10 April aided in the tightening of the orbit belonging to the spaceship around the solar, the tightening will help to bring the spacecraft near its destination: Mercury. This planet is least explored in the solar system by space explorers. 

European Space Agency stated that the Bepi-Colombo would be able to amass data to enhance a better understanding of Mercury. The operation consists of two orbiters, namely, the Mercury Planetary Orbiter, whose work is to explore the surface of the Earth. The other orbiter is Mercury Magnetospheric Orbiter (MMO), whose task is to provide a better view of the Earth’s magnetosphere. Earth’s magnetosphere is the magnetic bubble produced by the planet that protects its surface from radiations produced by the sun and cosmos. 

During the process, the ship was able to use two out of eleven constituents present aboard the MPO-the Italian Spring Accelerometer (ISA) and its magnetometer (MPO-MAG). On the other hand, the ship commenced on several passes, and the exploring device made a close journey towards our planet as it slid into the Earth’s shadow. Also, it listened to the magnetic fields of the Earth carefully before getting out of the Earth’s atmosphere. 

The approach of the Bepi-Colombo on Earth

The Italian Spring Accelerometer was in a position to capture 8 hours measurement from the board of Bepi-Colombo after soaring between 256,393 kilometers to 129,488 kilometers of distance above our planet. Since the accelerometer was searching for frequencies that are lower to hear by the human ear, the recordings had to freeze into one minute of sound, before undergoing some adjustments at (INAF). According to Carmelo Magnafico, one of the INAF team associates, he stated that the vibrations that are as a result of both external and internal factors are conveyed to the accelerometer. 

When the Bepi-Colombo slipped into the Earth’s shadow, it lost the sight of Earth for a 34-minute clip. The recording ends when the orbiter from the Earth’s sphere. 

The Bepi-Colombo noted the sound produced when the magnetosphere of our planet crashes with the solar wind. When the Bepi-Colombo passes through the outer surface of the turbulent magnetosphere, there’s the production of sound as well as it passes through the magnetopause, a point where Earth’s magnetic fields start to spread.
