Scientists have identified 26 new kinds of bacteria growing in NASA’s clean rooms, where spacecraft are constructed. These bacteria can survive in conditions resembling those in space, according to new studies published in Microbiome.
The research, from King Abdullah University of Science and Technology (Kaust) in collaboration with NASA’s Jet Propulsion Laboratory, presents an unexpected finding, as these clean rooms are designed to be sterile and free from contaminants.
NASA maintains strict control over temperature, humidity, and airflow in these environments to ensure they remain impeccably clean, making it seem unlikely for bacteria to exist there.
The researchers observed that some of these bacteria might tolerate radiation and harmful chemicals, raising the possibility that they could endure the harsh environments of space travel.
Dr. Kasthuri Venkateswaran, a Senior Research Scientist at the Jet Propulsion Institute at NASA and the lead author, remarked that this collaboration aligns with Saudi Arabia’s space ambitions and helps position Kaust as a frontrunner in microbiology and astrobiology research.
He expressed that together, they are uncovering the mysteries surrounding microorganisms capable of surviving extreme conditions typical of space.
Professor Alexandre Rosador, the principal investigator from Kaust, emphasized that understanding which microorganisms can survive space travel is crucial. He mentioned that it’s vital to prevent Earth bacteria from contaminating other planets during missions.
He noted, “Our study aims to understand the risks posed by these extremophiles during space missions by analyzing their genetic traits.”
Junia Schultz, a postdoctoral researcher involved in the study, stated that these microorganisms could have practical applications, not only as indicators of biohazards but also in developing new drugs, ensuring food safety, and potentially aiding future endeavors.
