Improved super-thin solar panels and nuclear fission are all in development to handle the massive logistical problems of meeting power needs in space. Fraser Cain takes viewers through the newest developments, including 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 data home.
Getting enough power in space is a big problem.
Many of these developments will eventually be part of energy solutions here on earth.
