Sustainable Life Support in Deep Space:
Closed-Loop Systems for Human Missions

Background

Multi-year deep space missions require revolutionary life support systems that can sustain human health and well-being with minimal resupply. This challenge addresses creating closed-loop systems that efficiently recycle air, water, and waste while producing food and maintaining psychological health during extended isolation from Earth.

Key Challenges

1

Achieving near-100% recycling efficiency for water and air

 
2

Growing sufficient food in confined spaces with limited resources

 
3

Managing waste products and converting them to useful materials

 
4

Maintaining system reliability over multi-year missions

 
5

Addressing psychological impacts of closed environments

 
6

Balancing system complexity with repairability

 
7

Preparing for medical emergencies without Earth support
