obsolete, but the superconducting antigravity repulsor beams launching stuff to LEO will be nuclear powered

Morelike 30 hours to transit a system but yeah, its wasteful. These days you'd want an electromagnetic brake to slow down and get captured by the target star.

>visiting for resource extraction is fine
the amount of propellant it would take to descend a medium to large gravity well, extract all the useful mass and then climb back up out it would be absurd. I'm not sure there's enough prop in the solar system for it. Not to mention, if there are any previous residents, you will lose your high ground advantage (they will take potshots at you with whatever they've got + lay traps for you). They'll probably also call you space gypsies for trying to steal their planet/moon.
