NASA’s New Space Engine Is Powered by Nuclear Fission

From a technology standpoint, there’s not too many greater challenges than nuclear power in space. The physics involved in it is quite intense — it has that luster of something totally different. We start with that highly enriched core, the splitting of the atoms generates that heat that we need at the right power levels, […]

The Problem of Power in Space. NASA’s New Kilopower Reactor

Space is the worst. It’s got hostile radiation, a total lack of atmosphere, near absolute zero temperatures, problematic gravity wells, and worse. In order to keep your spacecraft alive in that environment, you need electricity to keep it warm. Not to mention all the power to run scientific instruments and the transmitters to send that […]
