in my humble believes this question depends on: do we have enough resources to build something massive like the star trek space ship enterprise
Helium-3 on the moon, necessary fuel for nuclear fusion…….
„Helium-3 is considered a safe, environmentally friendly fuel candidate for these generators, and while it is scarce on Earth it is plentiful on the moon… As a result, scientists have begun to consider the practicality of mining lunar Helium-3 as a replacement for fossil fuels.„
So the moon could provide the fuel for space exploration……. and powering the energy needs on earth alike.
But where does the massive amount of titanium and other rare minerals like hematite should come from?
Remember that mars looks „rusty“ and was referred by ancient folks as „the god of war“?
Hematite, also spelled as hæmatite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. Hematite crystallizes in the rhombohedral system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950°C.
… now guess what they found on mars with their rovers? (c’mon… a trace of life would have been exciting on mars….. but a trace of gold not?;)
this is what the real „segourny weaver“ looks like:
Next Question: Will traveling space be a ridiculous pyjama-party? 😉
