About

L. Kerjean is a key figure in planetary seismology, best known for their instrumental contributions to the NASA InSight mission. Their primary research focuses on the deployment and operation of seismic instruments on extraterrestrial surfaces, specifically the SEIS (Seismic Experiment for Internal Structure) package. Kerjean’s most impactful work is the landmark 2019 paper, “SEIS: Insight’s Seismic Experiment for Internal Structure of Mars,” which has garnered 375 citations. This comprehensive study details the design and capabilities of the six-axis Very Broad Band (VBB) seismometer, a critical tool that, after 42 years since the Viking landers, finally enabled high-fidelity seismic monitoring of the Red Planet. By thoroughly characterizing the instrument’s performance and deployment strategy, Kerjean helped lay the foundation for InSight’s groundbreaking discoveries about Mars’ crust, mantle, and core. More recently, they contributed to the 2022 paper on the actual deployment operations on Mars, documenting the real-world challenges and triumphs of placing this sensitive instrument on another world. Kerjean’s work is essential for any student or researcher interested in the engineering and science of planetary seismology.
