NASA has conducted multiple experiments aboard the International Space Station focusing on how microgravity affects nutrition-relevant organisms, including alfalfa plants and spirulina algae. By studying plant-microbe interactions and the effects of reduced lignin in alfalfa roots, researchers aim to optimize plant growth suited for space environments and simplify recycling for successive generations.
Spirulina cultivation experiments target its potential as a nutritious protein source that also supports oxygen production aboard spacecraft. These studies help address challenges posed by long-duration missions to the Moon, Mars, and beyond, where producing fresh, sustainable food sources is critical for crew health and mission success.
