Agnirva Space Premier League - Expedition #31476: Fungi in Space: Assessing Crew Exposure to Microbes on the ISS

The Mycological Evaluation of Crew Exposure to ISS Ambient Air investigates the presence of fungal spores and other microbes in the air aboard the International Space Station. Led by Dr. Chiaki Mukai of JAXA, this study seeks to understand how fungi survive and spread in the closed environment of the ISS and what that means for astronaut health.

Fungi are resilient organisms. Some types can thrive in low-nutrient environments and tolerate extreme conditions. In space, they may become more virulent or resistant due to the unique environment.

The ISS is a closed-loop system, meaning air is recycled, and biological contamination can become a problem if not monitored. Fungal spores, once introduced, can settle into crevices and multiply, especially if there’s moisture or warmth.

This experiment involved collecting air samples from various modules on the ISS during multiple expeditions. The goal was to identify fungal species present and understand their concentrations over time.

The findings are crucial for maintaining astronaut health, especially on long missions. Fungal infections can be difficult to treat in space, and allergens from spores may affect respiratory health.

Additionally, understanding fungal behavior in space helps inform sterilization protocols and habitat design for future missions. Keeping the spacecraft clean isn’t just a matter of hygiene—it’s a matter of safety.
