Summary
Bioregenerative life support systems are scientifically feasible for space missions. These systems offer cost and weight savings for long-duration space platforms by recycling resources like water and oxygen.
Area of Science:
- Space exploration
- Life support systems
- Bioregenerative technologies
Background:
- Bioregenerative life support systems (BLSS) are crucial for long-duration space missions.
- Current life support systems present challenges in terms of mass and resupply.
- BLSS offer a sustainable solution for future space habitats.
Purpose of the Study:
- To assess the scientific feasibility of bioregenerative life support systems.
- To evaluate the potential cost and weight benefits of BLSS for space platforms.
- To outline the components and operational requirements of such systems.
Main Methods:
- Conceptual design and preliminary data analysis of BLSS.
- Integration of higher plants and/or micro-algae for resource generation and waste processing.
- Utilizing microbiological and physicochemical techniques for material recycling.
- Computer-controlled monitoring and management of system dynamics.
Main Results:
- Bioregenerative life support systems are scientifically feasible.
- Preliminary data indicate cost and weight savings for low Earth orbit platforms.
- BLSS can provide food, water, and oxygen while processing waste and carbon dioxide.
Conclusions:
- BLSS represent a viable approach for sustainable space exploration.
- Further research is needed on plant/algal physiology and system control.
- Flight experiments and ground-based facilities are essential for BLSS development.
