L’excellence passionnément
About
I am a researcher at ISAE-SUPAERO and part of the Space Systems for Planetary Applications (SSPA) team. I have a first class MPhys degree in Astrophysics from the University of Edinburgh (2007) and a PhD in Physics and Planetary Sciences from the Open University and the University of Nice-Sophia Antipolis/Côte d’Azur Observatory (2012).
I have an active role in several planetary science and planetary defense space missions : I’m a collaborator for the NASA InSight mission and for the Mars 2020 mission, specifically the SuperCam microphone onboard the Perseverance rover. I’m also a member of the NASA DART mission Investigation Team, have a leadership role in the ESA Hera mission, and am the Principle Investigator for an instrument (the WheelCams) onboard the CNES/DLR Martian Moons Exploration (MMX) rover that will be deployed to Phobos by the JAXA MMX mission.
My research interests are linked to understanding the physical properties and geophysical evolution of asteroids and terrestrial planets. I also study how space instrumentation interacts with the surface environment of planetary bodies in order to prepare inter-planetary space missions and to allow the most precise interpretation of the data possible.

Happy asteroid day !
What would it be like to walk on the surface of asteroid Dimorphos ?
“The boulders covering the surface of Dimorphos are much bigger than they might look,” says planetary scientist Naomi Murdoch of ISAE-Supaero in France, working on the CubeSat landings. “At around 5-7 m across, the largest ones are typically house-sized.”
Find out more in this article on the ESA website.

Last week I was lucky enough to visit Meteor Crater in Arizona (a 1-mile wide crater former by an asteroid impact 50,000 years ago). I’m glad we have space missions like DART and Hera that will help to avoid this happening again !

The rover MMX has a name : IDEFIX. Why ? Well the first french satelite (launched in 1965) was called Asterix and now the first french rover is called Idefix (this is the name of Asterix’s dog Dogmatix in French).

DART made the cover of Nature ! All the papers are open access and can be found here.
"In this week’s issue, five papers explore the test and the effects of the collision. One paper reconstructs the impact ; a second looks at the change to Dimorphos’s orbit caused by the impact. A third paper reports observations from the Hubble Space Telescope of the material ejected during the collision. A fourth paper uses modelling to characterize the transfer of momentum that resulted from the impact. And the final paper reports on citizen science observations before, during and after the collision."
Well done to all the DART team.

The fear that the sky could one day fall on our heads dates back to the dawn of time because the impact of an asteroid or a comet could dramatically change life on Earth in a fraction of a second. The dinosaurs have already experienced this. Does the same fate threaten the human species ?
Find out in this ARTE documentary (in french) for which I was interviewed : Le ciel va-t-il nous tomber sur la tête ?.
Also available on YouTube until the 04/03/2026.

NASA’s InSight Lander Detects Stunning Meteoroid Impact on Mars !
Credit : NASA/JPL-Caltech/University of Arizona
NASA’s InSight lander recorded a magnitude 4 marsquake last year, but scientists learned only later the cause of that quake : a meteoroid strike estimated to be one of the biggest seen on Mars since NASA began exploring the cosmos. What’s more, the meteoroid excavated boulder-size chunks of ice buried closer to the Martian equator than ever found before – a discovery with implications for NASA’s future plans to send astronauts to the Red Planet. More here.

NASA Confirms DART Mission Impact Changed Asteroid’s Motion in Space !
Prior to DART’s impact, it took Dimorphos 11 hours and 55 minutes to orbit its larger parent asteroid, Didymos. Since DART’s intentional collision with Dimorphos on Sept. 26, astronomers have been using telescopes on Earth to measure how much that time has changed. Now, the investigation team has confirmed the spacecraft’s impact altered Dimorphos’ orbit around Didymos by 32 minutes, shortening the 11 hour and 55-minute orbit to 11 hours and 23 minutes. More here.
The aftermath of the DART Collision with Dimorphos was also captured by the SOAR Telescope [Credit : CTIO/NOIRLab/SOAR/NSF/AURA/T. Kareta (Lowell Observatory), M. Knight (US Naval Academy]

The James Webb Space Telescope and the Hubble Space Telescope, have captured views of a unique NASA experiment designed to intentionally smash a spacecraft into a small asteroid in the world’s first-ever in-space test for planetary defense. These observations of NASA’s Double Asteroid Redirection Test (DART) impact mark the first time that Webb and Hubble simultaneously observed the same celestial target. More here.

DART succesfully impacted aseroid Dimorphos at 1h14 (CEST) this morning. What an amazing night. Look at those images, look at that surface ! Not only is the DART mission a HUGE success, but this is also the first time we’ve ever seen a binary asteroid up close.
September 26 2022
Tonight the DART spacecraft will smash into a 160 m asteroid at a speed of 24,000 km/hr. Why ? To test our capacity to protect our planet if we ever discover an asteroid on a collision course with Earth.

Asteroid Bennu Reveals its Surface is Like a Plastic Ball Pit
"The spacecraft would have sunk into Bennu had it not fired its thrusters to back away immediately after it grabbed dust and rock from the asteroid’s surface.
It turns out that the particles making up Bennu’s exterior are so loosely packed and lightly bound to each other that if a person were to step onto Bennu they would feel very little resistance, as if stepping into a pit of plastic balls that are popular play areas for kids."

The PIONEERS (Planetary Instruments based on Optical technologies for an iNnovative European Exploration using Rotational Seismology) project, led by members of the SSPA team here at ISAE-SUPAERO, has been funded by the European Commision as part of the H2020 call (H2020-SPACE-20-2018) ! The team will develop an innovative optical seismometer that provides 6 degrees of freedom measurements (3 translational and 3 rotational). The instrument will be built specifically for planetary science missions, and a reduced scale version of the instrument specifically dedicated to the exploration of small bodies will also be developped. The PIONEERS project involves a consortium of research laboratories (ISAE-SUPAERO, ETHZ, IPGP, ORB, LMU) and an industrial partner (iXblue).
