A series of biology experiments, called BioNutrients, is testing ways to use microorganisms to produce nutrients – off Earth and on demand – that will be critical for human health in space. Editor’s note: This article was updated on Aug. 19, 2025, to clarify which BioNutrients experiments in the series are completed and adds new information about the upcoming experiment, BioNutrients-3. In the future, NASA’s long-duration human exploration missions to the Moon and Mars will require minimizing the amounts of supplies launched, increasing reuse and recycling, and using local resources to make crucial products for crew during spaceflight. Certain supplies, such as vitamins, have a limited shelf life and are most effective freshly made. To meet these needs, NASA is developing technologies to ...
