Go JETSON: Space Force invests millions in compact nuclear reactor development

Plus: NASA plans 3D-printed lunar homes, 2x2 e-bike for the great outdoors, comet strike may have started agriculture. Solar panels and fuel cells have been the mainstays of power supply in space — think of the huge solar arrays on the International Space Station — but now Space Force is looking to use compact nuclear fission reactors for deep space missions. With multi-million dollar contracts awarded under the Joint Emergent Technology Supplying On-orbit Nuclear Power (JETSON) program, Space Force has challenged industry to develop miniature nuclear power plants able to provide abundant energy far from the Sun's rays. Freed from the confines of the inner solar system, future spacecraft could support exploration, habitation, and military operations far beyond Earth. But first, radical solutions are needed to save weight and shield crews from radiation. To learn more about how these problems might be tackled, and when we can expect to see results, jump to today’s [Must Read]( now. 😇 Also today, Generative AI is a boon in terms of how it can supercharge workflows, but how ethical and legal is it to use AI in business?

The goal is to extend missions beyond Earth orbit where higher energy is needed. Fission reactors could provide abundant electricity for future deep space operations by the Space Force and NASA. The companies will develop designs and technology like radiation shielding to enable practical fission power for spacecraft. The projects aim to minimize weight while maximizing energy output. Initial results are due by late 2025. Space Force is pioneering space-ready fission reactors to powering more ambitious exploration, and nuclear propulsion could open new capabilities like a sustained lunar presence. While many technical hurdles remain, investing now seeds innovations to help this technology come to maturity.
