About
Hunter Williams is a leading aerospace engineer whose work is central to the future of space exploration and *in situ* resource utilization (ISRU). His research focuses on the physical properties of extraterrestrial regolith—the loose, granular material blanketing the Moon, Mars, and asteroids—and on developing the robotic systems needed to interact with it. Williams’s most impactful contribution is the Pneumatic Sampler (P-Sampler), a NASA-provided instrument for JAXA’s Martian Moons eXploration (MMX) mission, designed to capture and return surface material from Phobos. This high-profile project, alongside his foundational 2018 paper on regolith surface properties (26 citations), has established him as a key figure in planetary sampling. More recently, Williams has pioneered technologies for lunar infrastructure, including the Lunar Array, Mast, and Power System (LAMPS), a deployable vertical solar array for the Moon’s poles, and a novel molten regolith electrolysis system that uses concentrated solar heating to produce oxygen. His work directly supports the Artemis program’s goal of a sustainable human presence on the Moon, bridging fundamental planetary science with the practical engineering of space resources.
