A New Sterilization Tool for Space Garments
Scientists have created a pen‑sized apparatus nicknamed the “laundry gun” that could clean astronauts’ clothing aboard spacecraft. The device employs plasma to kill microbes on fabrics.
The technology works by generating an electric field that produces a plasma cloud, which neutralizes bacteria and fungi on textiles. Because the unit is only a few centimeters long, it fits easily into the confined quarters of a space station.
Maintaining clean clothing is a challenge for astronauts, as conventional washing machines are unavailable in orbit and garments must often be worn for extended periods. A plasma‑based cleaning method could reduce logistical burdens and improve hygiene aboard long‑duration missions.
Potential Benefits of Plasma Laundry
- No water consumption, preserving limited onboard resources.
- Rapid processing, treating a garment in just a few seconds.
- No chemical residues that could contaminate cabin air.
Open Questions and Next Steps
While the concept looks promising, researchers still need to address power requirements and ensure plasma safety inside enclosed modules. Planned ground‑based experiments and microgravity tests will evaluate the system’s effectiveness and suitability for deployment on the International Space Station.
