I'm caused to remember Arthur C. Clark's "Rendezvous with Rama"
where he predicts that Mercury has huge energy potential and
so colonies there can be productive.
One little-parreciated factoid -- Mercury is the closest planet
to Earth. On average.
It zips around so fast it spends more time closer to Earth
than nay other planet.
But then it is also the closest planet to Saturn and Pluto
by the same logic. ;)

Yet although Mercury is "downhill" a trip there isn't easy, slowing to Mercury's orbital velocity requires more fuel than reaching Jupiter.
I thank both of you for mentioning those facts.
