US, Russia and China race to build nuclear reactors on the moon

The US, Russia and China are racing to put nuclear reactors on the moon to power lunar bases and mine frozen water in craters for drinking water, air and rocket fuel. NASA plans a reactor by the end of 2030; its Lunar Reactor 1 would produce 20 kilowatts for five years without maintenance. Russia, working with China, targets 2036. Scientists warn of contamination risks.
