NASA to test prototype Kilopower nuclear reactor
This is a very cool technology, but frankly I have a hard time imagining that it will see much use. NASA sees public protests and scare mongering whenever it tries to fly an RTG, which is based in the radioactive decay of (usually) plutonium, and does not use a nuclear chain reaction. They did fly one on Mars Science Lab, because it was the only way to get enough power for the rover. But it takes a PR hit every time it does so. RTGs are therefore only used when no other technology will work.<p>It think it&#x27;s likely that the public relations nightmare NASA would have to go through to fly an actual reactor will be through the roof.
