About

Huafeng Liu is a key figure in planetary seismology, best known for his instrumental role in the SEIS (Seismic Experiment for Internal Structure) project on NASA’s InSight Mars lander. His research centers on the design and deployment of ultra-sensitive seismometers for extraterrestrial environments, with a primary focus on understanding the internal structure of Mars. Liu’s major contribution lies in the development of the Very Broad Band (VBB) seismometer, a six-axis instrument capable of detecting ground motions as subtle as a fraction of an atomic diameter. This work culminated in the landmark 2019 paper "SEIS: Insight’s Seismic Experiment for Internal Structure of Mars," which has garnered over 375 citations and serves as the definitive reference for the mission’s seismic instrumentation. By enabling the first direct measurements of marsquakes and the planet’s crust, mantle, and core structure, Liu’s engineering and scientific achievements have fundamentally reshaped our understanding of terrestrial planet formation. His contributions represent a historic milestone in planetary science, bridging decades of ambition since the Viking missions with the reality of high-fidelity seismic data from the Red Planet.
