The “space race” is once again making headlines, with technology worthy of the 21st century. Like the Cold War–era competition, this race too is about showcasing power—but this time it's nuclear power.

A new article in Power Technology examines the competing efforts of the United States, Russia, and China as they strive to be the first to put a nuclear reactor on the moon to power a lunar base, detailing the technical challenges and international rivalries.

Russian space agency Roscosmos has announced its intention to build a nuclear reactor on the lunar surface in collaboration with the China National Space Administration. According to Roscosmos director general Yury Borisov, “Today we are seriously considering a project—somewhere at the turn of 2033–2035—to deliver and install a [nuclear] power unit on the lunar surface together with our Chinese colleagues.” The reactor would apparently be used to supply power to the Russian-Chinese International Lunar Research Station (ILRS), plans for which the two nations unveiled in 2021.

These plans come on top of previously announced plans of the United States and United Kingdom for lunar nuclear reactors.
