ESA plans to test producing Solein, a protein powder made from air and urine, aboard the ISS. Developed by Solar Foods, Solein uses microbes and urea to create protein, potentially supporting long-duration Moon or Mars missions. The HOBI-WAN project will first develop the technology on Earth, then test it in microgravity, aiming for Solein to become astronauts’ main protein source by 2035, enhancing autonomy and sustainability in space.
