Located 80 meters from the rover at the moment of take-off, the small helicopter rose to 5 meters above the ground before covering a distance of 133 meters before returning to land where it had taken off from. SuperCam's scientific microphone, developed by ISAE-SUPAERO, recorded the sound emitted by the rotation of the Martian drone's blades during its flight. This sound has a characteristic frequency of 84 Hz, equivalent to the low “E” of a piano or the bass voice of a human being. “This is a big surprise for the whole scientific team,” says Naomi Murdoch, a researcher at ISAE-SUPAERO who is studying the data from the microphone. "Tests carried out in a Martian atmosphere simulator to design this instrument, and our theories of sound propagation, indicated that the microphone would have great difficulty picking up the sounds of the helicopter. Indeed, Mars' thin atmosphere strongly attenuates sound transmission. We needed a bit of luck to record the helicopter from such a distance. We're very pleased to have succeeded in obtaining this recording, which is proving to be a goldmine for our understanding of the Martian atmosphere". Developed jointly by ISAE-SUPAERO and a consortium of CNRS laboratories and its partners, coordinated by CNES, SuperCam's microphone is derived from a consumer model adapted to withstand the Martian environment. It pursues 3 substantial scientific and technical objectives of the Mars 2020 mission: Study the sound associated with laser impacts on Martian rocks, to gain a better understanding of their mechanical properties. Improving our understanding of atmospheric phenomena (wind turbulence, dust eddies, wind interactions with the rover, and now with the helicopter). Understanding the sound signature of the rover's various movements (robotic arm and mast operations, driving on normal or uneven ground, pump monitoring, etc.). The microphone was first switched on a few hours after Perseverance landed. It recorded the first Martian sounds generated by turbulence in the atmosphere. It is used daily in conjunction with laser rock ablation for chemical analysis of Mars. ABOUT THE MARS 2020 MISSION: NASA is relying on Caltech's Jet Propulsion Laboratory for the development of the Mars 2020 mission. SuperCam was developed jointly by LANL (Los Alamos National Laboratory, USA) and a consortium of laboratories attached to the CNRS, French universities and research establishments. Several Spanish universities, led by the University of Valladolid, are also contributing to the instrument. CNES is responsible to NASA for the French contribution to SuperCam. The instrument is operated alternately from LANL and the French Operations Center for Science and Exploration (FOCSE) at CNES in Toulouse.
