Marion is an ESA OSIP PhD student at Politecnico di Milano in the DART Lab under the supervision of Prof. Francesco Topputo and at the European Space Agency (ESA-ESOC) with Dr. Lorenzo Bucci. She is working in mission analysis for future lunar exploration missions embedding human spaceflight safety and robustness constraints, working to build up a full European lunar architecture. She started working in mission analysis during her M.Sc. degree at ISAE-SUPAERO, studying transfers between NRHOs and Halo orbits. She then joined OneWeb as flight dynamics engineer, operating real-time a constellation and supporting its software development. She went on to become an ESA Graduate Trainee at the European Space Agency working in operations preparations for the Artemis IV mission to the Gateway, as well as future ESA lunar mission analysis. These experiences motivated her to continue to explore mission analysis, particularly when considering the constraint of human spaceflight.
