Agnirva Space Premier League - Expedition #30008: Hunting Microbes in Space: The 3D Monitoring System Keeping the ISS Clean

The International Space Station (ISS) may look clean and futuristic, but it’s also a habitat—one where microbes can thrive. The Three-dimensional Microbial Monitoring (3DMM) experiment, led by Dr. Kasthuri Venkateswaran from NASA’s Jet Propulsion Laboratory, focuses on keeping the space station’s environment safe.

This project monitored microbial activity onboard the ISS during Expeditions 64, 65, and 69. Unlike traditional sampling methods that require returning samples to Earth, 3DMM enables real-time, in-situ monitoring using advanced imaging and molecular analysis.

Microbes are part of our natural world, but in a closed environment like the ISS, they can pose health risks to astronauts and even damage equipment. The 3DMM system creates a spatial map of microbial presence, helping pinpoint hotspots for contamination.

The data from this research supports not only astronaut health and safety but also future deep-space missions where Earth-based analysis won’t be feasible. It also improves microbial monitoring systems for hospitals, submarines, and clean rooms on Earth.

The 3DMM experiment is a step toward autonomous space habitats that can monitor and maintain their own cleanliness, making long-term human presence in space more feasible.
