On August 5, 2025, acting NASA Administrator Sean Duffy announced a grand plan to land a nuclear fission reactor on the surface of the Moon by 2030. This is intended to gain a strategic foothold on the Moon by that time, the same time frame in which China prepares its first taikonaut to land there.
Besides geopolitical rivalry, the objective is to solve a very serious issue of power security required for sustained human occupation of the Moon and missions to Mars where sunlight may not be sufficient.
How Do You Protect the Reactor?
Protection has a specific concern very much on a nuclear reactor on the Moon. Lunar missions stir clouds of abrasive dust and broken rock known as regolith that can harm gear by sandblasting open surfaces. NASA will probably hide the reactor behind natural shields like huge rocks or place it beyond the horizon on the moon by at least 1.5 miles from landing sites to minimize the landing plumes effect to protect the reactor.

The past experience of Apollo 12 landing near the Surveyor 3 probe comes with increased concern over corrosion due to landing exhaust thus protection will be necessary in future and larger landers in future missions.
Where Do You Put a Nuclear Power Reactor on the Moon?
The balance accessibility versus resources will be the case to settle for the lunar reactor. The south pole largely has permanently shadowed craters in which the water ice life-support and fuel-manufacturing potential lie under the surface. NASA’s Artemis mission is focused on these. These places are likely to offer water and, more generally, the necessities for human life and use.
Further definition of the precise placement will require quite a bit of detailed information on where ice deposits are located, which scientists are now collecting from several lunar orbiters. Verification of these deposits will assist in mapping the optimal sites where nuclear powered sustainable lunar bases could be constructed.

What’s the Future of This Plan?
The reactor project is a very important step toward establishing human exploration beyond Earth in the long term. A stable source of power on the Moon will help to resource extraction and reduce dependence on Earth, thus enabling continued deep space missions including manned missions to Mars.
The technical challenges include selection of a site and dust mitigation; however, the global level of impulse in lunar exploration programs makes the reactor all the more significant. With NASA combining efforts with international partners and private corporations, this vision for a nuclear-powered base on the Moon probably will be realized within the next decade for paving ways toward man’s persistent presence outside Earth.
