Space rated nuclear reactors? Seriously Bezos, do your research, both RTG and uranium ones are used in space right now. (the latter mostly old soviet)

I hope he actually meant nuclear propulsion instead.

I think he is trying to compete for attention while Elon is out busy troubleshooting the most recent SpaceX explosion. The irony is that if Jeff joins hands with Elon, they may actually be able to colonize Mars sooner but that's not how free markets and competition work is it...
yeah imagine if Elon, Richard Branson, and Bezos combined forces and open sourced everything they discover in relation to space travel -- totally democratizing it. -- We'd get a lot further in half the time...my money's on Elon getting there first though.
I agree with you. Elon will get there first. You need a gorilla mindset to get to Mars and he has it over Jeff Bezos.
I wonder about this. Without the profit motive / investor dollars, would anything ever get done?
I think he meant propulsion. He mentioned that (paraphrasing) "it gets difficult the farther away form the Sun you go", which wouldn't be an issue for power generation for internal closed systems.

Let's go Bezos. Ressurect Project Orion.
