About
Troy Lee Hudson is a planetary scientist and engineer whose work has been central to NASA’s InSight mission, particularly in understanding the mechanical behavior of Martian regolith and overcoming the challenges of deploying the Heat Flow and Physical Properties Package (HP³) on Mars. His key research areas include planetary surface operations, robotic arm testing, and the physical properties of extraterrestrial soils. Hudson’s major contribution lies in his leadership of the anomaly recovery efforts for the HP³ “mole”—a self-hammering penetrator designed to reach 3–5 meters depth. When the mole stalled unexpectedly, Hudson coordinated extensive robotic arm testing on Earth, using InSight’s engineering model to diagnose the problem and develop a successful recovery strategy. His most-cited paper, “InSight Robotic Arm Testing Activities for HP³ Mole Anomaly Recovery on Mars” (2021, 4 citations), documents this critical work, which saved the experiment and provided invaluable insights into Martian soil mechanics. Though modest in citation count, this paper represents a landmark in planetary field engineering—a testament to Hudson’s ability to bridge laboratory simulation and real-world Mars operations. His efforts have directly shaped how future missions will handle subsurface sampling on other worlds.
