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 ...

A new technology, the Fission Fragment Rocket Engine (FFRE), requires small amounts of readily available, energy dense, long lasting fuel, significant thrust at specific impulse of a million seconds, ...

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 ...

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 ...

A nuclear fission fragment rocket engine (FFRE) that is exponentially more propellent efficient than rocket engines currently used to power today’s space vehicles and could eventually achieve very ...
