Researchers have discovered that microbes aboard the International Space Station can harvest valuable metals from meteorites, a finding that could have important implications for future deep space exploration. The microorganisms, including bacteria and fungi, are able to extract and concentrate metals like iron, nickel, and cobalt from the space rocks.

Why it matters

Understanding how microbes behave and interact with materials in the space environment is crucial as humankind looks to expand its presence beyond Earth. Microbes could potentially be used to extract and process resources from asteroids and other celestial bodies, reducing the need to transport heavy mining equipment from Earth.

The details

The study, conducted by researchers at Cornell University, involved exposing meteorite samples to microbes aboard the International Space Station. Over several weeks, the microbes were able to break down the meteorite material and concentrate the extracted metals. This process could be harnessed to support future space missions, potentially reducing the need for costly and complex mining equipment.

• The study was conducted aboard the International Space Station in 2026.
• The findings were published on February 16, 2026.

What’s next

Researchers plan to further study the potential applications of this microbial metal harvesting process, including its feasibility for use in future space missions.
