NASA accelerates plans for installing nuclear reactors on the Moon and Mars
In a strategic move to bolster its lunar and deep space exploration ambitions, NASA has announced plans to deploy a 100-kilowatt nuclear reactor on the Moon by 2030 [1][2]. This accelerated timeline is aimed at outpacing China and Russia, who have announced joint efforts to place a reactor on the Moon by the mid-2030s [2].
The primary objectives of NASA's plan include establishing a reliable power source for sustained human presence on the lunar surface, particularly at the South Pole, where solar power is less viable due to the moon's long nights lasting about two Earth weeks [1][2]. The reactor will also support the Artemis program's goals of returning astronauts to the Moon and building one or more bases by 2030 [1]. Furthermore, it will prepare for extended space exploration, including fueling prospective missions to Mars [2].
The reactor's deployment could potentially grant geopolitical leverage, as the first country to deploy a reactor on the Moon could declare a "keep-out" zone, inhibiting others from establishing a presence in the area [1][2]. This strategic race is a significant aspect of the broader U.S. effort to maintain leadership in lunar exploration amid growing Chinese-Russian lunar ambitions [1][2].
The Artemis program, aimed at returning to the Moon and establishing a lasting presence near the south pole, has faced repeated delays. The surface power needs for long-term human operations on Mars, including life support, communications, and mining equipment to collect surface ice, should be at least 100 kilowatts [3]. In December 2024, NASA formally committed to using nuclear power on Mars [4].
The push for nuclear power on the Moon and Mars is not new, as NASA has invested over $200 million towards developing small, lightweight fission power systems since 2000 [5]. The directive was signed by acting NASA chief Sean Duffy, who is also the U.S. transportation secretary [4]. The target for launch readiness is the first quarter of FY30, which is late 2029 [6].
However, progress on the project has been slower than initially expected, elevating the urgency of the new directive [2]. Notably, SpaceX's Starship, planned for the Artemis mission, is far from ready [7]. No power systems developed by NASA have progressed towards flight readiness [5].
In summary, NASA's accelerated nuclear power plan by 2030 is a critical strategic and technological step to support lunar bases and Mars missions and to secure leadership in the emerging lunar and deep space exploration landscape [1][2]. The shift towards prioritizing human space exploration over scientific research under President Donald Trump's second term is highlighted by this directive [8].

- The nuclear reactor planned for deployment on the Moon by NASA in 2030 falls under the broader category of space-and-astronomy technology, as it aims to provide a reliable power source for deep space exploration and human presence.
- As NASA's strategy for the Artemis program involves not only returning astronauts to the Moon but also building bases and eventually extending space exploration to Mars, the technology of nuclear power plays a significant role in both science and space-and-astronomy.
