interesting concept for planet-to-planet conflict. Think Mars vs Earth. Most infrastructure will be in orbit, so in a 'fixed' place. The spinnlauncher would be the equivalent of continental ballistic missels. You have a somewhat massive satellite. One ring with tethers with rockets on the end (10-12 maybe). a counter rotating weight. Spinn up while your planet is blocking observation and release. Since the missels are not using their engines you have basicly a 'stealth' launch. Or at least stealthier.

you could allways just refuel lunar Starship, bring it back to LEO and use any normal dragon to bring crew home...

This relative velocity looks extremely high to me. Considering that both are moving in the same general direction, a velocity above escape velocity sounds strange... I mean I don't say it is wrong. I am just surprised.

obviously the first town on a new planet has to be called first landing. Countless of Scifi stories tell us that. The real question is who will build it? I can envision a permanent laboratory.... but a town?

yeah but usually you don't launch rockets that size at this rate. Having a way to move booster and Starship seperatly to the launchpad and then stack them right there might be easier than stacking them somewhere else and then moving the whole stack.

Go the other way. Instead of bringing stuff home, use your free Spaceships as Trash haulers. Dump Radioactive Waste and such into the sun. And be paid for it of course. Governments spend billions waterproving old salt mines etc. to store radioactive waste...

quick, hit F9!!!

Ok i have a question. This might be pretty stupid, and i freely admit i have very limited knowlege about this stuff. So feel free to roll your eyes or something . Iron changes its behaviour pretty massively depending on stuff you mix in. Add some carbon -> steel. Add some trace amounts of other stuff -> steel with vastly different brittelnes, melting points and so on. Could this be possible for metal hydrogen ? Maybe you could make it metastable to a degree by adding the right mix of "pollution" ?

Maybe i am reading this wrong but...isn't that just a complicated way of Crossfeed? With Planes instead of Falcon Heavy?

now that is a cute little baby rocket!^^

I guess the least turbulence you would get on a train. Or in a car ;-)

Not selfless. You need to change your picture. Those Guys (Elon and Bezos) have more money than they ever need. They use that Money to "force" the reality to be like they want it to be. That is very egocentric. ;-)

Can't you use the new In-Vehicle interaction-thingy and simply move a structual part in position?

Just call it Bob. Or "that base over there". We need less dignity in our spacestuff or some idiot might put a flag on it and start a war.

using my 10 fingers, i take my smartphone, write a small app with a button and a counter that goes up every time i hit that button(30 min max developing time). Now i can count almost abitrarily high with only one hand! :-P Addendum: using a long to store the count i could count to 9,223,372,036,854,775,807 ...everything after that requires some thinking/google.
