NASA asks contractors for a lunar reactor ready to launch by December 2030
Version 2: New Korean business coverage adds detail rather than new developments: NASA's 20 kW target is about one-100,000th the output of a large South Korean reactor and could fit in one or two containers, and CBS NoCut News reports that Washington also plans a nuclear-powered Mars mission by December 2028, with no core facts disputed.
In short
NASA has asked contractors to prepare a nuclear reactor able to operate near the lunar south pole and be ready for launch by December 2030, according to a New York Times report cited by Korean outlets. The agency moved ahead of Chinese and Russian plans to run a 10 kW reactor named Selena on the Moon by 2036, with Korean coverage citing Russian experience in space nuclear power. Experts cited by the outlets expect the deadlines to slip and warn of radiation risk if a launch fails.

NASA has asked contractors to prepare a nuclear reactor that can operate near the lunar south pole and be ready for launch by December 2030, according to a New York Times report cited by Korean outlets. Newsis, Dong-A Ilbo and Hankook Ilbo said the approach was made in late August and that the reactor must survive space travel and work without maintenance. Yonhap reported it must run for more than five years without servicing, with a power target of 20 kW, about the electricity used by 16 American households. [ 1 , 2 , 3 , 4 , 5 , 6 ]
The outlets described the move as a response to Chinese and Russian plans. Yonhap, Hankook Ilbo and Dong-A Ilbo reported that China and Russia aim to build a 10 kW reactor named Selena by 2036 and run it for ten years, and that Washington fears their reactor would effectively close off part of the lunar surface. Yonhap said nuclear power is a condition for the permanent bases the countries plan, because solar and radioisotope power are not stable through the two-week lunar night. [ 1 , 3 , 4 , 5 , 6 ]
Russia holds the current advantage, according to Yonhap: it launched more than 30 reactors on satellites in the 1970s and 1980s and holds a major supply of low-enriched uranium, described as the safest fuel for space use. Mikhail Kovalchuk, director of the Kurchatov Institute, told the state TASS agency that Russia has “virtually no competitors” in space nuclear energy. The United States launched a reactor-carrying satellite in 1965 and stopped operating it, Dong-A Ilbo said, after another spacecraft accident; Yonhap, Hankook Ilbo and CBS NoCut News said Washington has spent more than $20 billion on space nuclear programmes without redeploying a reactor. [ 1 , 3 , 4 , 5 ]
Experts cited by the outlets expect the deadlines to slip. Yonhap and CBS NoCut News reported that no country has a lander able to set heavy radioactive material down on the uneven lunar surface, that no reactor has been installed in low gravity and that the power needs of a base not yet built are unknown. Hankook Ilbo said the reactor design may change several times. [ 1 , 4 , 5 ]
On safety, Yonhap reported that the United States and Russia say the reactor will stay inactive until it arrives and the uranium fuel will be cooled, so little radiation would be released if it fell to Earth, but that a rocket explosion at launch or a reactor falling into the sea could cause a release. It cited the Soviet satellite Cosmos 954, which spread radioactive material over about 124,000 sq km of northern Canada in 1978, a figure Hankook Ilbo also gave. MIT professor R. Scott Kemp said that with insufficient shielding even a small accident produces more radioactive fallout and that weak lunar gravity could throw debris far; Edwin Lyman of the Union of Concerned Scientists warned that mixing nuclear power into the space race could create a potentially far more dangerous situation. Yonhap added that both countries plan to leave spent reactors on the lunar surface. [ 1 , 4 ]
CBS NoCut News said the three countries are also competing to secure lunar resources such as water ice and helium, and that the United States plans to send a spacecraft to Mars using nuclear power by December 2028. Hankook Ilbo noted the scale: a large South Korean reactor of 1,400 MW produces about 100,000 times the power of the planned 20 kW lunar unit, though the reactor could be built as small as one or two containers. [ 4 , 5 ]
Why it matters
The plans put nuclear power at the centre of US, Chinese and Russian efforts to build permanent lunar bases, where solar generation is unreliable through the two-week lunar night. Outlets report that specialists doubt the stated timelines and warn that a launch accident could release radioactivity, citing the 1978 crash of the Soviet satellite Cosmos 954.

Still unclear
- Whether the 2030 and 2036 targets can be met. Experts cited by Yonhap, Hankook Ilbo and CBS NoCut News expect the deadlines to slip, and no document carries an official confirmation or denial.
- Which contractors received NASA's request, what the programme will cost and where the reactor would be built or launched from. No document names the contractors, a budget or a location.
- The radiation risk of launching and operating the reactor. US and Russian assurances that it stays inactive until arrival and uses cooled fuel appear alongside scientist warnings in Yonhap, which does not reconcile the two positions.
- Whether China has delegated the lunar reactor work to Russia. Only Dong-A Ilbo states this, and it presents it as known rather than sourced.
- A US plan to send a spacecraft to Mars using nuclear power by December 2028. Stated only by CBS NoCut News, a tier-2 business outlet.
- That the competition is also about pre-empting lunar territory and resources such as water ice and helium. Stated only by CBS NoCut News.
