Sorry, but Mars colonization is nonsense. It isn't going to happen in the foreseeable future and the people that believe this stuff are no less stupid than the ones following the next messiah. I wrote about it here:

Just to put this into perspective a bit: every little bit of civilization in Iceland, every nail, every staple, every fruit, every tool has to be flown in or brought in by boat. Everything. And Iceland is a place that compared to Mars is paradise. The only things they have plenty of are energy, fish and sheep. And on Mars you wouldn't even have that.

It's just too silly to take serious.

Musk and Hughes have a lot in common. They are both genius, wealthy, capable and at times a bit batty. I'm fine with Elon being a bit batty, if that give us electric cars, reusable rockets and more. But I'm not buying into the cult. Starlink is borderline for me. I can see the utility. But the idea that space can be commercialized with such total disregard for what effectively is our largest commons is simply wrong to me.
