[[Beret Guy]] runs to wake up [[Cueball]], who is probably under the covers in bed, with his potentially middle of the night revelation that Humankind is discovering "{{w|exoplanet}}s" or planets that exist outside of our solar system. The indication is that these planets are habitable enough for humans, even if just for a visit.

Then Beret Guy takes it a bit further thinking that one of the countries on Earth could restart {{w|Project Orion (nuclear propulsion)|Project Orion}}. As Beret suggests, Project Orion was an early project to produce a spacecraft that would ride the shockwave from a series of nuclear bombs it dropped in order to travel very, very fast. However, the one major downside of Project Orion was the fallout that the launching of any such craft would present on Earth. One could try to boost the Orion spacecraft into orbit with conventional rockets, but Orion spacecraft are heavy β€” being composed of giant pusher plates and rows upon rows of nuclear bombs, they are hard to lift. On top of this, the {{w|Nuclear Test Ban Treaty}} means that the craft would be flatly illegal to build and launch on Earth, no matter what you did. However, if an asteroid mining project were to be started, the Orion drive spacecraft, the nuclear bombs, and all the infrastructure needed to man, build, and crew it could all be built safely in space, well away from the Earth's fragile biosphere, where little harm could be done. Some commercial spaceflight programs are interested in starting asteroid mining in the future, or even now: For example, see: https://www.planetaryresources.com.
