Detection of Earthquakes through a STratospheric INfrasound studY
Using long-lasting rovers on Venus is impossible. We want to use balloons.
Because of extreme conditions on Venus surface, we will use atmospheric balloons instead of rovers. Specifically, the final objective is to use a constellation of long duration balloons in the tropopause, where the temperature is around 55oC and pressure drops down to 0.5 bar. Each of them would embed pressure and position sensors, allowing the triangulation of the sources of the infrasonic waves propagating through the atmosphere. Such waves are in particular generated by quakes, which allows us to study the internal structure of the planet.
The DESTINY experiment aims at testing this method on the Earth's stratosphere. Our goal is to characterize the infrasonic background of the atmosphere to be able to recognize specific signals and to locate their origins. We will use explosions on the ground as infrasound sources, but we will also look for other specific signals. To do so, we will measure the phase difference between the signals detected by distinct on-board barometers and process it to locate their origins.
This project is developped in the frame of the BEXUS project, which allows us to fly our experiment on a stratospheric balloon.
The BEXUS projects within the REXUS/BEXUS programme allow students from universities and higher education colleges across Europe to carry out scientific and technological experiments on stratospheric research balloons. Each year, two balloons are launched, carrying up to 12 experiments designed and built by student teams.
Our team is composed of students from École Polytechnique.
