Nuclear fission, discovered in 1938, involves splitting an atom's nucleus, releasing energy. It's essential for electricity ...

Fission-powered rockets could halve the time it takes to get to Mars, but there's the whole issue of actually building one ...

NASA plans to send crewed missions to Mars over the next decade – but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip.

Testy Subject Scientists have long proposed nuclear fission-fueled rockets to get to Mars fast — but one is warning that ...

NASA plans to send crewed missions to Mars over the next decade – but the 140 million-mile (225 million-kilometer) journey to ...

Nuclear fission reactors act as a key power source for many parts of the world and worldwide power capacity is expected to ...

NASA and DARPA are developing nuclear thermal propulsion (NTP) technology to enable faster crewed missions to Mars, ...

Chernokov radiation is used to detect antineutrinos released from fission reactions in a detector that could cost $100 ...

Discerning whether a nuclear reactor is being used to also create material for nuclear weapons is difficult, but capturing ...

Unlike nuclear fission—the nuclear reaction that is currently used in the energy sector—fusion does not create radioactive waste. It produces three to four times more energy than fission and ...

Oklo, whose name comes from the region of Gabon, Africa where self-sustaining nuclear fission reactions took place naturally about 1.7 billion years ago, went public in May. Sam Altman, the CEO of ...

In that context, it’s easy to see why nuclear is appealing: Fission reactors can run uninterrupted for years, working at maximum capacity over 90% of the time. Maintenance outages tend to be ...
