Lunar Regolith Densometer, Liam Lee, Vincent Innocenzi

Williams Honors College, Honors Research Projects

Testing of extraterrestrial rovers is a growing concern as lunar exploration as an industry is becoming increasingly commercialized. Currently, the way rover testing is conducted is on a soil regolith which is already available. The structure of the soil, however, is harmful to humans and requires a full bunny suit and respirator to be worn during the conduction of the experiment. This limitation, along with the expensive price tag, prevents college university students and companies from establishing a rover test area in labs. The goal of the overall project is to create a safer testing environment by mimicking the soil-to-tire …

Thermal Radiation Effects On Particles From Plasma Arc Radiation, Reece Davis, Joseph Mcgee

Williams Honors College, Honors Research Projects

Understanding the radiation heating and transport of both microparticles and nanoparticles is a phenomenon that is critical for both space and Earth sciences. In space, these particles are heated by plasma arcs within ionized space clouds or solar flares and can be present the path of deep space missions and orbital satellites. While on Earth, processes such as forest fires, nuclear fusion, and microchip manufacturing include the plasma arc heating of particles. These particles lay within the Mie Scattering Regime and Rayleigh Scattering Regime and emit radiation differently based on their diameter. New mathematical and computational modeling has been conducted …

Automated Soil Resetting System For Extraterrestrial Regolith Simulation, Parker W. Brennan, Anthony C. Daniels

Williams Honors College, Honors Research Projects

This project focuses on designing an automated soil resetting system for extraterrestrial regolith simulation. The system will prepare a regolith simulant testbed to a desired, repeatable density, enabling reliable wheel–terrain testing for planetary rover research. Manual soil preparation currently exposes testers to hazardous particulates and produces inconsistent results.

The proposed system will integrate mechanical and control elements to reset the soil bed safely and efficiently. A combination of raking and vibrational methods will be explored, with feedback sensors and automation to achieve target density control. The research will proceed through literature review, benchtop experimentation, prototype design, and full-scale testing over …

Modeling And Testing Chain Trencher Excavator And Cone Penetrometer Robotic Prospecting Systems For Lunar In-Situ Resource Utilization, Marcello C. Guadagno

Dissertations, Master's Theses and Master's Reports

The Artemis Missions aim to establish a sustained human presence on the Moon, requiring In-Situ Resource Utilization (ISRU) of water-ice deposits in permanently shadowed regions. Two critical capabilities must be developed to enable ISRU at scale: prospecting instruments that can characterize the spatial distribution and geotechnical properties of icy regolith in situ, and excavation systems that can extract hardened icy regolith efficiently. This dissertation addresses both needs through the development and testing of a Percussive Heated Cone Penetrometer (PHCP) for geotechnical prospecting and a chain trencher excavator for icy regolith mining.

The PHCP was developed across eight design iterations and …
