Alexandre Le Roch has received the ISAE-SUPAERO Foundation thesis prize for his work!

A 2015 graduate of the Institut National des Sciences Appliquées in Rennes (INSA Rennes), Alexandre started his thesis at ISAE-SUPAERO in 2017 after spending some time at STMicroelectronics in Singapore. Vincent Goiffon, a professor at ISAE-SUPAERO, and Cédric Virmontois of the Centre National d’Etudes Spatiales (CNES) supervised his thesis, carried out with support from CNES and the French Alternative Energies and Atomic Energy Commission (CEA - Commissariat de l’Energie Atomique et aux Energies Alternatives).
His thesis work dealt with the study of the effects of nuclear and space radiations on CMOS image sensors, the goal being to improve space instruments and plasma diagnostics for nuclear fusion. More precisely, the study focused on the crystal defects induced by the radiation causing an increase in dark current. These studies contribute to improving our understanding of the physical principles at work in silicon affected by radiation.
Alexandre is the author or co-author of 11 publications. He has presented his work at the RADECS 2017, NSREC 2018, IISW 2019 and NSREC 2019 international conferences. He won various awards while he was working on this thesis. These include the international “Paul Phelps Award” grant from the NPSS chapter at IEEE (Institute of Electrical and Electronics Engineers) as well as the award for the best student article and best article at the RADECS 2019 conference. Alexandre also took part in opening the IEEE student branch at ISAE-SUPAERO in 2017 and presided over it until 2020.
Alexandre Le Roch defended his thesis in July 2020 and is currently working as a research engineer at ISAE-SUPAERO in collaboration with CNES. His research activities focus on the behavior of CMOS image sensors in contact with radiation for future missions that will explore the Jovian system (Jupiter), a very severe radiative environment. He will soon join the Goddard Space Flight Center (GSFC) at NASA to pursue this work on imaging systems’ behavior in contact with radiation. He sums up his thesis for you in 3 minutes flat
This thesis prize was presented by the ISAE-SUPAERO Foundation for the excellence of the research carried out and the outlook for the thesis’ applications.

French SUPERCAM instrument records audio from INGENUITY’s Fourth flight! NASA/JPL-Caltech/LANL/CNES/CNRS/ISAE-SUPAERO

Perseverance was parked 80 metres from the small rotorcraft, which rose to five metres and then hovered before flying downrange for 133 metres and returning to its take-off and landing spot. SuperCam’s science microphone, developed by ISAE-SUPAERO, recorded the sound from the helicopter’s whirring rotors during the flight. The sound registered 84 hertz, equivalent to a low E note on the piano or a bass voice type.
“This is a wonderful surprise for the science team!” said Naomi Murdoch, a research scientist with ISAESUPAERO who is studying the data captured by the microphone. “Testing in a Mars atmosphere simulator to design this instrument and our sound propagation theories led us to believe the microphone would find it very difficult to discern sounds from the helicopter. As Mars’ atmosphere is very tenuous, it really attenuates sounds. So we needed a bit of luck to pick up the helicopter from this range. We’re thrilled to have obtained this recording, which is going to be a gold mine for our understanding of the planet’s atmosphere.”
Developed jointly by ISAE-SUPAERO and a consortium of laboratories attached to the French national scientific research centre CNRS and partner laboratories, coordinated by CNES, SuperCam’s microphone is derived from a consumer model adapted to withstand the Martian environment. The microphone is pursuing three science and technology goals of the Mars 2020 mission:
Study the sounds generated by laser impacts on Martian rocks to better understand their surface mechanical properties.
- Seek to gain new insights into surface atmospheric phenomena such as wind turbulence, dust devils and wind interactions with the rover, and now with the helicopter.
- Analyse the sound signature of the rover’s movements, for example when it is using its robot arm, driving on flat or rugged terrain, and operating its pumps.
The microphone was first turned on a few hours after Perseverance’s landing, picking up the first sounds on Mars from atmospheric turbulence. It is used daily in combination with laser-induced breakdown spectroscopy (LIBS) to analyse the chemical make-up of Martian rocks.

Paul Planeix (S2020) has received the Mayoux-Dauriac Award from the ISAE-SUPAERO ENSICA Alumni Association SapienSapienS

Paul Planeix (S2020) has received the Mayoux-Dauriac Award from the ISAE-SUPAERO ENSICA Alumni Association. This prize recognizes engineering students in the final year of the ISAE-SUPAERO engineering course for their practical achievements during their studies and the various internships carried out, in keeping with the wishes of Maurice Mayoux. (S 1924).
The €3,000 Second Prize for 2020 went to Paul Planeix for his drone project, “Search & Rescue”. Development of a flight simulation environment / contributions to de Guidance, Navigation and Control systems at Zipline International.
Paul has worked on many scientific projects in a wide variety of fields during his engineering studies.
A member of the CubeSat association, he contributed to the construction of a 1:1 scale model of the MONA nanosatellite. His studies at ISAE-SUPAERO also enabled him to qualify a drone navigation system and to take his first steps in research through an exoskeleton control project. This research project, based on Machine Learning methods, was carried out with the Enorev’ association, the goal being to help children suffering from cerebral palsy.
While working on his double degree at Stanford University, Paul built an aircraft using a search and rescue scenario that was totally autonomous from takeoff to landing.
Paul then managed to join Zipline, at the time still a young startup in Silicon Valley specialized in robotics. He had an internship there with the Guidance, Navigation and Control (GN&C) team, which only had two members at the time. He contributed to the development of a drone simulation environment and to GN&C systems.
Today, Zipline operates the first and largest drone delivery system in the world in Rwanda, Ghana and the United States, providing a solution to the problem of the last mile in the healthcare field. This solution saves lives by providing maximum availability of essential medical products while reducing waste and maintaining the cold chain.
Paul has continued to contribute to the Zipline mission since 2020 through the skills he acquired at ISAE-SUPAERO and Stanford as an engineer.
Paul Planeix received the award for the variety, the excellence of his educational background and the practical achievements that brought him into the startup ecosystem.
The Mayoux-Dauriac Award is given in recognition of the use of knowledge acquired at the School in the exercise of one of the various facets of the engineering profession, and for the utility of the projects undertaken to industry and services with a positive economic balance.
