The U.S. Department of Energy has issued a request for ideas from the private sector on how to develop nuclear power plants that can operate on the moon and Mars. This is part of the government's efforts to build sustainable lunar and Martian bases that can support long-term human exploration of these extraterrestrial environments.

Why it matters

Nuclear power is seen as a critical technology for enabling long-term human presence on the moon and Mars, as it can provide reliable and abundant electricity to support habitats, life support systems, and in-situ resource utilization. The development of these nuclear reactors for lunar and Martian applications could also have broader implications for advancing nuclear energy technology on Earth.

The details

The Department of Energy is seeking ideas from private companies, research institutions, and other organizations on the design, development, and demonstration of nuclear reactors that can operate reliably in the unique environmental conditions found on the moon and Mars. Key requirements include the ability to generate at least 10 kilowatts of electrical power, operate for at least 10 years without the need for refueling, and withstand the launch stresses and radiation environments of space travel.

• The Department of Energy issued the request for ideas on April 15, 2026.
• Responses to the request are due by June 30, 2026.

What’s next

The Department of Energy plans to review the submitted ideas and select the most promising concepts for further development and potential demonstration.
