Spectrum Blue’s innovative Q-field technology provides a passive antimicrobial defence in space habitats to enhance crew health and maintain air quality by preventing microbial growth without the need for traditional cleaning methods. Space bacteria and space fungi are real words. NASA has identified several microbes that have evolved into space-native organisms alongside their human hosts. The International Space Station (ISS) has long taught us that maintaining a clean and healthy environment in microgravity is not just about aesthetics; it is a matter of crew health, system integrity, and scientific reliability. As highlighted by the ISS National Lab’s work on designing safer space habitats, microbial growth and surface contamination behave differently – and often more persistently – than on Earth. While the International Space Station provides today’s primary operational environment for microbial control, the rapid expansion of commercial spaceflight, lunar infrastructure, and long-duration exploration missions will place even greater emphasis on effective antimicrobial strategies. As human presence extends to commercial space stations, lunar habitats, spacecraft for deep-space missions, and other extraterrestrial facilities, preventing microbial contamination will …
