>If it weren’t for Musk & Bezos

SpaceX was built on NASA contracts like the original resupply missions, they won that contract before Falcon 9 had made its first flight. Its as odd as saying if it was not for Boeing and Lockheed Martin the airforce would not be able to fly.

Had SpaceX not been in the crew program that would have gone to Sierra Nevadas Dream Chaser and Boeings Starliner (the later having now built a system to fly NASA contracted astronauts. ).

"Not the best of timing for aurora sky watchers across northern Europe and North America, however a moderate (G2) geomagnetic storm is currently in progress. A watch for Strong (G3) conditions has been added. The Bz component of the interplanetary magnetic field (IMF) has been tipped south, a condition known to fuel geomagnetic conditions around the polar zones."

By this logic, no scientific research should take place for fear it could be used for military applications. The issue isn’t one particular country - all countries use scientific research to further their military and geopolitical aims.

What I’m saying is humanity is the issue and until we look beyond an ‘Us Vs. Them’ mentality we’ll always been a stone throws away from destroying ourselves.

…. Theres no paucity of ambition the goal is to buil a moon base and get to Mars that’s a huge ambition.

Ok that sounds good.

Depends on what you defending a moorbaden as I’m sure they could create some kind of habitation for people with a hundred tons. And even if we don’t get to that we still put the first woman on the moon and first person of colour which would be a huge success.

If it was impossible why are the brilliant minds at NASA planning it?

Ok

Ok interesting idea thanks for explaining.

Idk I disagree on some stuff like if it was truly impossible NASA would not be attempting it

It doesn't have to be the superior way to create everything. Rockets require virtually all custom parts. Custom parts require custom machining and don't get the benefits of economies of scale. Having one machine that can create all of those custom parts cuts out the requirement for custom machining and they don't need to change the machine if they make adjustments to the parts. Strongbacks on the other hand are relatively simple truss structures. You can use mass produced parts to build up the strongbacks fairly easily and inexpensively. There's really no reason why they couldn't print the strongbacks, but it doesn't really make sense to.
