The European Space Agency (ESA) has launched the HOBI-WAN project, an eight-month study aboard the International Space Station to develop protein powder from bacteria, aiming to reduce resupply missions for future Moon and Mars crews. Utilizing Solein, a protein-rich powder produced by Solar Foods through the fermentation of Xanthobacter, the project addresses challenges such as gas fermentation in microgravity and safety, while also employing urea from human waste to support bacterial growth. This initiative seeks to create a sustainable food source tailored for long-duration space missions.
