I’ve grown up with rockets that burn chemical fuel, but NASA’s next big leap in propulsion could make those engines look as dated as steam trains. By turning to nuclear power in space, the agency is ...

Human crews headed for Mars are still looking at journeys that last most of a year, long enough for radiation, boredom and mechanical risk to pile up. Nuclear propulsion promises to compress that ...

This study will identify primary technical and programmatic challenges, merits, and risks for developing and demonstrating space nuclear propulsion technologies of interest to future exploration ...

How can nuclear propulsion help improve deep space missions by significantly reducing the amount of time to reach Mars and beyond? This is what a recent study published in Acta Astronautica hopes to ...

IMO's sub-committee has prepared a work plan to develop a safety regulatory framework to support the uptake of new propulsion technologies and alternative fuels.
