“Think of it like a transcontinental railroad — not the fastest way to move a lot of mass, but certainly the most efficient,” Jared Isaacman said about nuclear electric propulsion.

Nuclear chemist Tim Gregory joins Big Think to make the case that nuclear energy can still transform the world for the better.

There are real concerns with long-term power generation on the Moon; nuclear could be the answer. But for NASA, will the cost be too high?

Planets can create nuclear power on their own, naturally, without any intelligence or technology. Earth already did: 1.7 billion years ago.

New telescopes, radio dishes, and gravitational wave detectors are needed for next-generation science. Will the USA lead the way?
