Agnirva Space Premier League - Expedition #32217: SOPHie’s ON hamSTER: Growing Sustainable Protein in Space

What if we could grow nutritious food in space using just microbes? That’s the idea behind SOPHie’s ON hamSTER, a quirky-named but highly innovative experiment led by Eugene Wang and supported by NASA. This project explored the viability of cultivating protein-rich microalgae in microgravity aboard the ISS during Expedition 73.

Sophie's BioNutrients developed a fermentation process using microalgae that could convert organic waste into protein. In space, where storage and resupply are limited, this approach offers a sustainable food source for astronauts. The experiment investigated how microgravity affects growth rates, biomass yield, and nutritional content of the cultures.

Beyond supporting astronauts, the research has applications on Earth. It could help produce food in arid or resource-limited regions, turning waste into value. The project aligns with broader goals of circular agriculture and bio-manufacturing, essential for future Mars colonies or lunar habitats.

The collaboration with BioServe ensured safe handling and monitoring in space. Results will inform future systems that combine algae with other life-support technologies like oxygen generation and waste recycling.
