>>14223783What's the good real estate in the Solar System?
Earth... we live here.
The Moon... it's close, fairly safe, pretty easy and economical to get to with the right systems. Potentially resource rich. Strategically located.
Mars... resource rich. Most habitable place in the Solar System except for Earth. Reasonably easy to get to with the right rocket. Difficult to land on and launch from.
Callisto and Ganymede... only Moons of Jupiter of any real mass that don't have fatal radiation exposure (Callisto is better than Ganymede for this, and Europa is deadly). Easy to land on and live on. Pretty Moon-like. Jupiter is very difficult and expensive to get to.
Titan... Moon of Saturn. Likely extremely resource rich and habitable with the right technology. Extremely far away (expensive, complicated travel). Landing is as difficult as landing on Earth (very complicated). Cold and remote.
And that's pretty much it. There are some Smaller bodies worth visiting and maybe economically exploiting (Enceladus, asteroids). And others which would be interesting to visit with probes for scientific purposes (Europa). But in terms of HUMAN Habitation and colonization? Hundreds of solar system bodies, and the list of "Prime Real Estate" is about 6 destinations long.
And all of them are progressively harder to get to and/or land on. And keep in mind, unlike the Space in fiction (which is really about the ocean), travel through space is miserable for human biology. Permanently space bound vehicles like the Enterprise transiting planets? Not happening. In the real world, Space is the gulf between worlds and everything interesting and important, insofar as people are concerned, happens on the planets and moons that dot that gulf. Probing that void is the job of unmanned probes and sending a manned mission to orbit Neptune (for example) for the sake of sending people there is not going to be a thing, regardless of propulsion technology.
