The human body contains 10 times more microbes than human cells, and bacteria and fungi grow in and on just about everything around us on Earth.<\/p>\n
Most bacteria are harmless, and many are beneficial or even essential to human functioning and well-being. But microgravity can make some microbes more likely to cause disease and bacteria and fungi may affect the function of spacecraft systems, by, for example, corroding metal. These organisms also could contaminate other planetary bodies that spacecraft and humans land on.<\/p>\n
Some microbes inevitably come along for the ride on crew members and cargo traveling to the space station, and it is important to identify and control those that may be harmful \u2013 especially in a closed environment like a spacecraft. Multiple investigations have tracked, identified, and analyzed the station\u2019s tiniest residents to help keep crew members and equipment \u2013 and even other planets \u2013 safe from any potential threats.<\/p>\n
A current investigation, ISS Boeing Antimicrobial Coating<\/strong>, tests surface coatings designed to inhibit the growth of microbes to protect crew members and equipment on a spacecraft. On Earth, such coatings could help reduce diseases transmitted from touching surfaces in aircraft cabins, health care facilities, public transportation, and other settings.<\/p>\n\n\n\n![\"McArthur,](\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/01\/antimicrobial-coatings-megan-mcarthur.gif?w=1190\")
