Abstract

The SuperCam Mars 2020 Microphone, a collabora- tion between ISAE-SUPAERO, IRAP in Toulouse and the Los Alamos National Laboratory (LANL), will record sounds from the surface of Mars in the audible range. It will support SuperCam Laser-Induced Breakdown Spectroscopy (LIBS) investigation by recording LIBS shock waves but it will also record aeroacoustic noise generated by wind flowing past the microphone. Here we use Computational Fluid Dynamics to study the interaction between the wind and SuperCam, by means of Direct Numerical Simulations. The goal is to understand how the microphone signal can be used to determine the wind speed and direction on Mars.
