Deep space probes and frontline soldiers share a basic problem: once they leave the grid, every watt has to be carried in. That constraint has shaped mission design for decades, from bulky ...

Radioisotope thermoelectric generators (RTGs) are the power plants of the interplanetary spacecraft. Or at least they have been for going on 50 years now. But they have significant drawbacks, the ...

A spacecraft power system that combines the technological know-how of engineers and scientists at the University of Leicester and NASA Glenn has passed its first test with flying colours. In late 2024 ...

Zeno Power's first full-scale radioisotope power systems will be fuelled by strontium-90 material recycled from a legacy radioisotope generator under a new public-private partnership with the US ...

Powering spacecraft with solar energy may not seem like a challenge, given how intense the sun's light can feel on Earth. Spacecraft near the Earth use large solar panels to harness the sun for the ...
