New Nuclear Rocket Concept Could Slash Mars Travel Time in Half

gizmodo.com Passant Rabie 2025-09-25 20:00:58

Engineers from Ohio State University are developing a new way to power rocket engines, using liquid uranium for a faster, more efficient form of nuclear propulsion that could deliver round trips to Mars within a single year. NASA and its private partners have their eyes set on the Moon and Mars, aiming to establish a regular human presence on distant celestial bodies. The future of space travel depends on building rocket engines that can propel vehicles farther into space and do it faster. Nucl

The US is trying to kick-start a “nuclear energy renaissance”

arstechnica.com Unknown 2025-09-25 13:23:03

In May, President Donald Trump signed four executive orders to facilitate the construction of nuclear reactors and the development of nuclear energy technology; the orders aim to cut red tape, ease approval processes, and reshape the role of the main regulatory agency, the Nuclear Regulatory Commission, or NRC. These moves, the administration said, were part of an effort to achieve American independence from foreign power providers by way of a “nuclear energy renaissance.” Self-reliance isn’t t

Companies that have dug deep into AI have fallen in love with nuclear power for its promise of 24/7 electricity. Meta, Google, and Microsoft have all made deals with startups or reactor operators. But does the nuclear industry love AI back? Yes, with caveats. No one is proposing to let an AI run a reactor, but power companies are increasingly interested in the technology’s potential to tighten things up on the business side, Bradley Fox, co-founder and CEO of Nuclearn, told TechCrunch.

America’s First Private Nuclear Fuel Recycling Facility to Open in Tennessee

Nuclear energy is among the most promising alternatives to fossil fuels—if we can find a sustainable way to take care of the unwanted, radioactive waste generated by the process. Stakeholders from both the public and private sectors have suggested various solutions, but a Tennessee firm will be the first to actually build and operate a U.S.-based recycling facility for nuclear fuel.

Experts Concerned AI Is Going to Start a Nuclear War

AI is starting to make experts on nuclear deterrence very nervous. Specifically, they say that a widespread push to integrate AI into virtually every level of military decision-making is creating a "slippery slope" in which AI will either be given the power to launch nuclear weapons itself, or the humans with that power will become so reliant on its guidance that they'll do so if it tells them to.

A Tiny Diamond Defect Could Be Blocking Fusion Breakthroughs

Every part of a fusion reactor is designed for maximum efficiency. Well, in theory, at least. In reality, the materials chosen to bring us closer to fusion don’t always perform as expected, leading to structural glitches that obstruct fusion reactions.
