Understanding how extraterrestrial soils behave is essential for almost every aspect of future exploration; from landing and construction to excavation and mobility. In an upcoming study, I will explore the surface and mechanical properties of Lunar and Martian regolith simulants, with the goal of linking microscopic features to macroscopic behavior in realistic environments.
This work will be carried out in collaboration with Dr. Manos Anyfantakis (www.anyfas.com), a researcher with strong expertise in interfacial and particle-scale phenomena. Together, we aim to investigate how the surface energy, morphology, and particle interactions of regolith simulants influence their cohesion, compaction, friction, and flow.
Our approach combines:
-
Surface and structural characterization techniques, such as imaging, profilometry, and contact angle measurements,
-
Mechanical response testing, focusing on cohesion, angle of repose, and shear strength,
-
And the integration of simulation and modeling tools, to interpret and scale up the observed behaviors.
This study is not only intended to inform future in-situ resource utilization and mobility systems on the Moon and Mars, but also to build a more predictive understanding of how granular materials behave under reduced gravity and atmospheric conditions.
By combining material science, tribology, and simulation, we hope to contribute to the development of safer and more efficient technologies for off-Earth operations; and to open up new paths for interdisciplinary collaboration in this evolving field.
