ESA is turning air into food for space missions
ESA has announced HOBI-WAN, a wild new project that turns air into food for astronauts heading to the Moon or Mars.
By using special microbes that grow from gasses, they're hoping to make protein-rich meals in space—no farms or supply rockets needed.
The big idea? Astronauts can stay healthy and independent on longer missions, and maybe even help solve food issues back on Earth.
Solein protein powder
ESA is teaming up with Solar Foods from Finland to use Solein, a protein powder made from hydrogen, oxygen, and carbon dioxide.
It's packed with nutrients (about 70% protein!) and doesn't need soil, sunlight, or much water—perfect for space.
If it works out, this tech could cut down mission costs and offer a new way to feed people in tough places here on Earth too.
