Space Food: Turning Urine into Protein for Astronauts

The European Space Agency is exploring a unique idea to keep astronauts fed during long space missions.

The Protein Powder: Solein

• Made using air, microbes, and electricity
• Involves a special bacterial culture
• Fed with hydrogen, oxygen, carbon dioxide, and urine

The Goal: Resource Recycling

• Recycle waste produced by the crew and life support systems
• Make space missions more self-sufficient
• A game-changer for long-term space travel

The Project: HOBI-WAN

• Hydrogen Oxidizing Bacteria In Weightlessness As a source of Nutrition
• First tests will be done on Earth
• If successful, technology will be tested on the International Space Station

The Impact

• Could improve astronauts' well-being
• Could make long-duration missions possible
• Includes trips to the Moon and even Mars
• Seen as a key capability for the future of space exploration

Criticisms and Focus

• Critics might wonder about taste and practicality
• Focus is on sustainability and innovation
• Find ways to survive with limited supplies
• Crucial for the future of space travel
