Mining in space could spur sustainable growth

Area of Science:

• Economics
• Environmental Science
• Space Exploration

Background:

• Economic models typically treat Earth as a closed system regarding resources.
• Declining space launch costs (e.g., by Blue Origin, SpaceX) make extraterrestrial resource extraction increasingly feasible.
• Current mining practices on Earth have significant environmental and social costs.

Purpose of the Study:

• To investigate the economic and environmental implications of transitioning from Earth-based to space-based mining.
• To explore how space mining could support continued economic growth and metal use.
• To provide a research foundation for sustainable development through space resources.

Main Methods:

• Analysis of cost trends in rocket launches.
• Examination of geological factors relevant to space mining.
• Assessment of environmental impacts of mining on Earth versus in space.
• Extension of a neoclassical growth model to incorporate space resource acquisition.

Main Results:

• Space mining has the potential to decouple metal use from Earth's environmental constraints.
• A transition to space mining could facilitate continued economic expansion.
• Significant reductions in environmental and social costs on Earth are possible.

Conclusions:

• Space mining offers a potential pathway to sustainable economic growth.
• Further research is needed to fully understand and harness the benefits of space resources.
• This study provides a framework for exploring the role of space mining in mitigating Earth's environmental challenges.
