Analysis: Why NASA wants to build nuclear reactor on the moon
NASA and international partners are planning to install nuclear reactors on the moon to support long-term lunar bases. These reactors are essential for providing consistent power in the moon's south pole region, where solar energy is unreliable due to extended periods of darkness.
Why it matters
Nuclear power is a strategic necessity for the next phase of space exploration and the potential industrialization of lunar resources.
NASA wants to install a nuclear reactor near the moon’s south pole by 2030. Its planned output, 20 kilowatt (kW), could power a few households on earth. Russia’s planned reactor for the International Lunar Research Station (ILRS), led by China, will produce around 10 kW. But the fact that they are nuclear makes them significant.
The U.S. and China are pursuing parallel efforts today — in partnership with other countries — to be the first to set up a semi-permanent, and in future permanent, moon base. Such a facility will need electricity for everything from heating and life-support to recharging rover batteries.
