About
J. Knollenberg is a planetary scientist whose research has centered on Mars exploration and subsurface geophysical investigation. Working as part of the international team behind NASA's InSight mission, Knollenberg has made meaningful contributions to our understanding of Martian interior properties through involvement with the Heat Flow and Physical Properties Package, known as HP³. This sophisticated instrument was designed to measure Mars's surface heat flow by deploying a self-hammering penetrator — nicknamed "the mole" — to depths of three to five meters beneath the Martian surface. Knollenberg's work spans both the operational planning and scientific analysis phases of the HP³ experiment, contributing to pre-landing mission operations documentation as well as post-deployment analysis of the unexpected soil properties encountered on Mars. The mole's struggles to penetrate the Martian regolith revealed surprising cohesive soil characteristics, and Knollenberg's research helped derive critical soil property data from the penetration attempts themselves — turning a technical challenge into a scientific opportunity. With citations accumulating across publications from 2018 to 2021, Knollenberg's contributions reflect the collaborative, problem-solving spirit essential to planetary exploration, offering future mission designers invaluable insights into Martian near-surface geology.
