Novel propulsion ideas for moving around space seem like they're a dime a dozen recently. Besides the typical argument between solar sails and chemical propulsion lies a potential third way—a nuclear ...

It's one thing when NASA alone wishes to design something. With an annual budget that wouldn't cover sharpening the pencils in the military-industrial complex, there are bound to be some shortcomings.

The NASA Innovative Advanced Concepts program recently awarded grants to different companies for the development of future explorations in space, including a company called Positron Dynamics. This ...

NASA’s push for a new nuclear rocket engine is not just another upgrade to the hardware we strap to the bottom of spacecraft. It is an attempt to rewrite the basic rules of how far, how fast, and how ...

Startup Dark Fission Space Systems announced plans on March 22 to build and demonstrate a nuclear thermal rocket engine in orbit within five years. The company is developing a nuclear thermal rocket ...

The role of nuclear power may be up for debate on Earth, but in space, fission tech makes a lot of sense. The U.S. military—after already awarding Lockheed Martin with a contract related to the DRACO ...

If you ask some people, humanity has more than proven its worth as a space-faring species. In a few short decades, we’ve gone from flying piston aircraft in our own atmosphere to sending people and ...

Novel propulsion ideas for moving around space seem like they’re a dime a dozen recently. Besides the typical argument between solar sails and chemical propulsion lies a potential third way — a ...

Nobody said building a fusion power plant would be easy. Physicists and engineers have been working for decades to crack the problem. But over the last year or so, fusion startup Zap Energy took a ...

U238 is NOT a fissile material. U235 is the fissile isotope of Uranium. You can get some energy out of U238 by hitting is with fast neutrons, which is what the patent suggests, but it won't support a ...
