Meeting with Marie-Bertille Mosnier
Why did you join the S-Cube?
"I started launching rockets at secondary school because there was a club run by Planète Sciences. I continued at secondary school, and then in preparatory school. In July 2018, I became a volunteer in the Planète Sciences association for the quality control of student rockets. It was the first time I had met S-Cube students. Two months later, I joined Supaéro and was called to join the S-Cube and even take charge of the two projects monitored by CNES for which they needed a project manager!"
What are the highlights of your experience?
"CNES steered us towards a project involving an orbital nanolancer with the possibility of a SpaceX-style return. There was no budget, so it was a real challenge. We first came up with a solution using fine grids and fins to rotate the rocket without using the engines. The idea wasn't taken up, but we did get €20,000 for trials the following year. Then there was Covid, but we went back to this project in 2021-2022 with a different angle of attack. A friend, Ruben Jaoui, a fluid mechanics student, had the idea of creating a calculator to avoid certain ranges of mechanical resonance that could affect the rocket's balance and trajectory. We created this calculator for CNES, and in doing so demonstrated the high technical level of ISAE-SUPAERO students!
What have these years at S-Cube brought you?
"When I joined the S-Cube, I was expecting to be involved in technical design, like I'd known from the rocket clubs I'd attended in secondary school and at prep school. But I very quickly found myself doing project management, which was completely new to me. In my 2nd year, I became a project manager, in other words a systems engineer with an overall view of the project. That taught me a lot about technical management, team management and the human side of things.

Perseverance collects first Martian sounds: explanation by Dr. Naomi Murdoch & Dr. Alexander StottDr Naomi Murdoch, researcher in space instrumentation and planetary science, and Dr Alexander Stott, post-doctoral fellow, tell us more about the physical characteristics of Mars' atmosphere, in particular the speed of sound and its attenuation. These analyses were published in Nature on April 1, 2022 by an international team led by a teacher-researcher from Toulouse III - Paul Sabatier University, and including scientists from CNRS and ISAE-SUPAERO.

FRENCH SUPERCAM INSTRUMENT RECORDING THE SOUND OF INGENUITY'S 4th FLIGHTLocated 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.
