Somebody needs to resurrect Gerard O'Neals space colony idea first.
And we would save a fortune in launch costs if they would build a EM catapult. Instead of wasting a fortune on stuff that is designed to burn up.

I would prefer a laser launch system. Could double as a defense system. [:D]

Well it would but a laser of that power is a little beyond us. However it is within our technology to build a laser system that would work off the MOON- where there is no drag and the gravity is 1/6 earth. That would be useful for lifting the building materials to build colonies ect.
Another thing about NASA, they over build everything. I am sorry but there is no way the habitat modules of the ISS are exposed to more stress than the hulls of our Nuclear Submarines. We do not build our subs in cleanrooms. We do not build our subs out of exotic alloys, we use steel, high grade steel but still steel. Why cant space station parts be made the same way?
Also, why do all spacecraft be multimission? Travel to space SHOULD be done in stages. First up to orbit at the ISS. Then from the ISS in a special spacecraft that is little more than a pressure chamber with thrusters to a nother pressure chamber that is geosinc. Then another simple spacecraft to another unmanned pressure chamber/garage at the L1 point between earth and moon. There you get on the lunar lander and down to the station on the moon. Every part is reusible and every part is a single purpose unit.
