About

Dr. Linda Facto is a leading figure in planetary science and astrobiology, renowned for her instrumental role in designing and deploying cutting-edge geophysical and spectroscopic instruments on Mars. Her research focuses on planetary interior structure, surface geochemistry, and the search for biosignatures. Dr. Facto was a key architect of the SEIS (Seismic Experiment for Internal Structure) instrument on NASA’s InSight lander, a six-axis seismometer that, after 42 years, finally enabled the first direct measurement of marsquakes and the internal layering of the Red Planet. This seminal work, published in *Space Science Reviews* (2019), has garnered over 375 citations, fundamentally reshaping our understanding of Martian tectonics and core dynamics. More recently, she led the SHERLOC investigation on the Perseverance rover, a robotic arm-mounted spectrometer that uses Raman and fluorescence imaging to map organic compounds and minerals. This 2021 paper, with over 237 citations, has been critical in selecting samples for future return to Earth, identifying potential chemical biosignatures in Jezero Crater. Dr. Facto’s contributions bridge the gap between planetary geology and the search for life, making her a pivotal voice in the next era of Mars exploration.
