About

Dr. Baptiste Chide is a planetary scientist whose work is reshaping how we listen to—and understand—the surface of Mars. His primary research focuses on the development and application of acoustic and spectroscopic instruments for planetary exploration, particularly through the lens of the NASA Mars 2020 Perseverance rover. Dr. Chide is a key figure behind the SuperCam instrument suite, contributing to its landmark 2020 paper (322 citations) which details the body unit and combined system tests for this versatile remote-sensing package, capable of laser-induced breakdown spectroscopy (LIBS) and Raman spectroscopy. His most distinctive contribution, however, is the Mars Microphone onboard SuperCam (2023), a pioneering instrument that captures the first audio recordings of another world. By analyzing the sound of laser sparks and wind, Dr. Chide’s work provides novel insights into Martian atmospheric properties and rock hardness, effectively adding a new sense to planetary science. This innovative approach has established him as a leading voice in planetary acoustics, demonstrating how sound can reveal physical properties invisible to traditional imaging and spectroscopy.
