"A lunar nuclear reactor may sound dramatic, but its neither illegal nor unprecedented. If deployed responsibly, it could allow countries to peacefully explore the Moon". After an eyebrow raise at this one, there may be benefits to powering lunar exploration with low-carbon energy
NASA plans to build a nuclear reactor on the Moon – a space lawyer explains why, and what the law has to say
Nuclear reactors in space may sound like something out of science fiction, but they are likely to prove important for powering long-term space missions.
