Constraining the evolution of the magnetic field of terrestrial planets has important implications concerning the planets’ evolution of their thermal state, composition, atmosphere, climate and ultimately of their habitability over geological times. Rocks are instrumental in enabling us to track this evolution because they record it through their property of acquiring and preserving magnetization. Deciphering rocks’ magnetic record relies on the acquisition, processing and interpretation of spacecraft magnetic field measurements on the one hand and laboratory measurements of planetary samples on the other.
During my work as a PhD student at IPGP in Paris, France and as a postdoctoral researcher at GFZ in Potsdam, Germany I became familiar with the possibilities, challenges and constrains involved in using spacecraft measurements to this end. My desire to expand my skill set and work directly with magnetized samples has led me to the Paleomagnetism Lab at MIT in December 2019 as a postdoctoral Marie Sklodowska-Curie Global Fellow. My project, which is being carried out also in collaboration with IPGP, is entitled “Deciphering the magnetic record of planetary rocks using spacecraft and laboratory measurements”. In particular, at this stage, I focus on constraining the evolution of the Martian magnetic field. For this, I use magnetic field measurements obtained by the spacecrafts Mars Global Surveyor (MGS) and Mars Atmosphere and Volatile Evolution (MAVEN). Moreover, I perform laboratory measurements on Martian meteorites using high-end instrumentation, including the SQUID magnetic microscope and the Quantum diamond microscope (QDM).
