And while the reactors aren’t looking to do Bray-style misadventures, it’s easy to see why the stable, decades-old RTG that powers Voyager 1 and 2 is a role model for the next generation of ...

Nuclear energy has been powering spacecraft for decades. NASA's Voyager 1 and Voyager 2 probes, New Horizons spacecraft, and Curiosity Mars rover, along with many other robotic explorers, employ ...

Nuclear reactors are not an unusual feature in space; the Voyager 1 and 2 spacecraft, now whizzing through deep space after departing our solar system, have been running on nuclear energy since ...

Atomic batteries are great for spacecraft on decades-long missions because they just keep going and going. Their giant terrestrial counterparts, “melted-down” nuclear reactors, share this trait.

A refrigerator-sized nuclear fission reactor built by NASA just completed a significant test. Known as KRUSTY (an acronym that stands for Kilopower Reactor Using Stirling Technology), the ...

Exactly half a century ago this week, a rocket shot off from the California coast. It carried the U.S.’s first and only (known) space nuclear reactor, SNAP-10A, which has been circling the Earth ...
