How ESA plans to make astronaut food from thin air for Moon and Mars missions

Europe’s space agency is pioneering a groundbreaking project, HOBI-WAN, to generate protein from gases like hydrogen and carbon dioxide in space. This innovative technology, developed with Solar Foods, could provide astronauts with a sustainable food source, reducing reliance on Earth resupply missions for long-duration Moon and Mars journeys. The experiment aims to prove the viability of gas-based fermentation in microgravity.
