Duffy reveals plan for nuclear reactor on the moon 

Sean Duffy, Transportation Secretary and interim NASA Administrator, announced a fast-track plan to develop and build a nuclear reactor on the moon.

The initiative is framed as part of a competitive “race to the moon” primarily aimed at surpassing China in lunar exploration and establishing a sustained human presence.

The big picture: Duffy emphasized the critical need for reliable energy to power lunar bases, noting that while some lunar areas will use solar power, nuclear technology is essential for continuous energy supply, especially in locations where solar power is less feasible. • The reactor under development is intended to generate 100 kilowatts of power, roughly equivalent to the energy consumption of a 2,000-square-foot home for three and a half days, highlighting that the t
