Imagine a future where astronauts on long-term space missions can feast on a protein-rich meal, all made from something as simple as their own urine and the air around them. But here's where it gets controversial... While this innovative space food concept may sound like something out of a sci-fi movie, it's actually closer to reality than you think. The European Space Agency (ESA) has launched a pilot program called HOBI-WAN, which aims to test the feasibility of creating a protein powder called Solein using just microbes, air, and electricity. Solein relies on urea, an organic compound found in urine, as a nitrogen source for protein synthesis. The protein powder, developed by Finnish startup Solar Foods, will be tested by the ESA in a future mission aboard the International Space Station. This marks the first time the technology used to develop the powder will be used in a space environment. But the real question is: How will this space food made from astronaut pee taste? And will it be a hit or a miss among astronauts? ESA says the first phase of HOBI-WAN will focus on developing the technology on the ground before testing it in a microgravity environment like space. Developers hope Solein will be widely used by space agencies by 2035. So, will this space food made from urine become a reality? Stay tuned to find out!
