-3 is part of an experiment series testing ways to use microorganisms to produce these nutrients in space and on demand.

The on-demand nature of this experiment is similar to making nutrient-dense fermented foods on Earth, such as how milk is transformed by good bacteria into yogurt. But in this case, there is a focus on producing specific types and quantities of nutrients essential for future space explorers.

Samples from BioNutrients-3, along with

Once the samples return to Earth, the science team at NASA’s Ames Research Center in California’s Silicon Valley will perform analysis procedures. Results from this study can help NASA develop methods to produce vital nutrients that could support human deep space exploration as part of NASA’s

Oscar Roque, engineer for NASA’s BioNutrients-3 project, works at a console on Oct. 2, 2025, at the Multi-Mission Operations Center at NASA’s Ames Research Center in California’s Silicon Valley. The facility allowed the BioNutrients team to remotely observe experiments conducted by crew members aboard the International Space Station and communicate with astronauts in real-time.
