Is NASA too pessimistic about space-based solar power?

Area of Science:

• Space Engineering
• Energy Systems
• Economics

Background:

• The concept of space-based solar power (SBSP) involves collecting solar energy in orbit and transmitting it to Earth.
• Historically, the high cost of space launch and infrastructure has been a major barrier to SBSP development.

Discussion:

• This analysis evaluates the economic viability of SBSP in light of recent advancements in launch vehicle technology.
• The potential cost reductions offered by new rocketry capabilities are central to the economic feasibility assessment.

Key Insights:

• While current estimates indicate significant upfront investment for orbiting power stations, emerging rocketry breakthroughs present a pathway to economic viability.
• The cost-effectiveness of SBSP is strongly dependent on continued innovation and scaling in the space launch sector.

Outlook:

• Further research is needed to refine cost models and assess the long-term economic and environmental benefits of SBSP.
• Successful implementation of SBSP could revolutionize global energy production and contribute to climate change mitigation efforts.
