Musk's speaking is always a little awkward (in an endearing way), but did he seem significantly more nervous/emotionally affected than usual in the first part of this speech? It seemed that way to me, curious if anyone else interpreted it like that. He calms down when he starts talking about risk and it being the anniversary of a launch. edit: Good and fun presentation regardless! edit2: Thoughts: - Maybe he feels in…

#32Back of the envelope calculation for the price of an Earth-to-Earth ticket: Musk's stated goal is $500k/ticket to Mars. It's a shorter trip, so perhaps ~5x as many passengers in the same volume (i.e. 500 total; cf. a380 which seats 850). It takes five (?) orbital refuel trips for the martian journey, but we'd need none of those. Depending on how much less than a full tank the passenger vehicle needs (payload could be…

#34Nothing on Moon Base Alpha except a picture. Would be nice to have a timeline for this (maybe the gap years where Mars transit is too long?)

#37So what's the carbon footprint of one of these launches? Did I understand correctly that we can make the fuel by taking CO2 from the atmosphere? That would make the footprint negative, would it? That seems to good to be true.

#38Earlier quoted context omitted.
I was a little disappointed he didn't give any timeline at all on that not even a aspirational one. I also assume it's gonna be really expensive due to frequent heat shield replacement. I wouldn't be surprised if it never became economically viable. Too few passengers and too high cost.
I imagine they can fit 400 passengers though. No need for those cabins or even a need to give passengers drinks.
If he can get the cost down to US $10 million per trip, that's US $12K per person.
