Deeper Dive
My project, the Moondust Magnet, is an electrostatic device designed to capture hazardous lunar regolith from the air inside lunar habitat airlocks. If inhaled, lunar regolith can cause severe respiratory irritation, and repeated exposure may contribute to chronic lung disease and cellular damage. Although additional research is needed, my work demonstrates that bipolar interdigitated embedded electrode arrays may be a viable method for protecting astronaut health and maintaining habitat integrity during extended lunar missions in the coming decades.
The idea began while I was conducting a literature review about preventing rocket plume damage and studying electrodynamic dust shields, which use electrostatic waves to repel lunar regolith from surfaces. I had this aha moment and thought, if electrostatic waves can repel lunar dust, could they also attract it? That question eventually developed into my current project, which focuses on capturing airborne regolith inside lunar airlocks.
Completing this project required me to overcome several technical and personal challenges. Much of the work was conducted independently from my school, so I had to teach myself unfamiliar concepts in electrostatics, experimental design and data analysis.
I see my work improving quality of life by helping protect the people who will live and work on the Moon during future long-duration missions. Lunar dust may seem like a minor inconvenience, but it can quickly become a huge issue because it exposes astronauts to potentially serious health risks. By capturing dust before it reaches the habitat, my work could reduce astronauts’ respiratory exposure to lunar dust and extend the operating life of filtration equipment. This would allow lunar crews to devote more time to scientific research, exploration and other mission objectives during their stay on the lunar surface. More broadly, I hope my project contributes to the infrastructure needed for a permanent and sustainable human presence on the Moon and Mars. Protecting astronauts from long-term lung and cellular damage is not only an engineering challenge; it is an essential step toward ensuring safe future space exploration.
