China and Russia want to jointly establish a permanent presence on the moon. How these outposts can be supplied with energy during the long moonlit night is one of the important questions in the preparation.

The head of the Roscosmos space agency, Yuri Borisov, has now explained that his country is considering building a nuclear reactor to supply the station. The move has nothing to do with the recent warnings from US security circles that Russia could station a nuclear weapon in Earth orbit, Borissov said.
