Scientists create 'laundry gun' for astronauts to clean their clothes by shooting out plasma
If you have ever shared a room with multiple people for days on end, you may know how clothes and living conditions can rapidly turn rather smelly. Imagine that happening in a confined spacecraft. Even worse, since water on a space mission is in short supply, space travelers can't easily do their laundry. This is more than a body odor problem — unclean clothes and linens are ripe feeding grounds for infectious bacteria. Astronauts might wear the same clothes for days or even weeks, seal away used clothes in airtight bags , then return them to Earth for cleaning or cast them away to burn up in Earth's atmosphere. This is fine for short trips near Earth, but what about a months-long odyssey to Mars ? Engineers have devised a new way for astronauts to dry-clean their dirty laundry.
