Thuwal, Saudi Arabia — KAUST and NASA scientists have discovered 26 space-resilient microbes in NASA spacecraft cleanrooms. These ultra-clean labs are built to avoid contamination, yet they host organisms with traits fit for space. This surprising find helps explain how microbes might survive extreme space conditions like radiation and vacuum.
The research, published in Microbiome, shows how certain bacteria can endure environments once thought unlivable. These microbes, known as extremophiles, show resistance to stress, including high radiation and low nutrients. The study supports NASA’s cleanroom protocols and reflects Saudi Arabia’s rising role in space science through the Saudi Space Agency.
Microbial Survival in Space: Traits Behind Space-Resilient Microbes
The bacteria found in cleanrooms carry genes that help them resist harsh conditions. These include radiation resistance, spore-forming ability, and strong DNA repair. As a result, they can stay alive in space-like environments for long periods.
Dr. Kasthuri Venkateswaran, a retired NASA scientist, called the project a key step. “This partnership supports Saudi Arabia’s vision and places KAUST at the front of microbial and space science,” he said.
Planetary Protection and Cleanroom Microbes
KAUST Professor Alexandre Rosado, who is also part of NASA’s planetary protection team, stressed the policy’s impact. Knowing which microbes survive in spacecraft helps shape future mission rules.
This study allows agencies to improve how they clean spacecraft before launch. This helps avoid the accidental spread of Earth microbes to other planets. For Saudi Arabia, this work also boosts its growing science and space efforts.
The Saudi Standard’s View: A Strategic Step Toward Scientific Sovereignty
This discovery strengthens Saudi Arabia’s leadership in microbial science and space policy. KAUST’s role in global research shows a deeper national goal. That goal is not only an investment but a long-term partnership and innovation. As the Kingdom grows its space presence, findings like this show a clear path forward: ethical, collaborative, and world-class science.
