But that's when looking at things from down here. On a galactic level, we've only begun to scratch the surface of what's possible, and no matter how many milestones we’ve reached with our space ...

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 ...

Fission Fragment rockets are several proposed nuclear rocket designs made since the 1980s with the highest potential theoretical top speed. The fission-fragment rocket is a rocket engine design that ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. This relatively long transit time is a result of the use of traditional chemical rocket fuel. An alternative technology to the ...

The dream of nuclear fusion has been chased by some of the world’s brightest minds for decades. It’s easy to see why — replicating the inner workings of stars here on Earth would mean virtually ...

The space agency is investing in the development of a propulsion system that uses nuclear power to create plasma bursts. Reading time 2 minutes The future of space travel depends on our ability to ...

An international team of scientists has identified an unexpected region of heavy, neutron-deficient isotopes in the nuclear chart where nuclear fission is predominantly governed by an asymmetric mode.

A five-dimensional (5D) Langevin approach developed by an international team of researchers, including members from Science Tokyo, accurately reproduces complex fission fragment distributions and ...
