Going to have huge environmental and health problems if one blows ups or burns on the pad

Seems like most of the discussion here on NSF was that 39A was not able to handle a rocket of this size, but Musk seems confident it will. Any thoughts?

I don't see any reason the booster and tanker can't support moon missions while MCT is at Mars. May not be Elon target but I doubt he will say no to the money if demand is there. If they can do Mars for <$500k think how much moon would be.

throttle capability 20-100%.

Maybe the booster doesn't start with all engines firing? Can they ignite all 42 while in flight?

And people complain about frakking causing earthquakes this is going to be an seismic earthquake machine.

And a real operational mess, at the very least, on a landing mishap (if, as on the video, it's not just return-to-launch-site, but return-to-launch-pad).

Why does Elon hate landing bingo?

What happens if the booster and/ or tanker has an issue are all those colonists left twiddling their collective thumbs in orbit.

I realize its highly simplified, but I cant imagine them being able to hoverslam back onto the launch mount

Smart move is to reverse the launch order. The fuel doesn't get quite so impatient as the passengers.

Easiest answer would be to just build a giant fuel depot in orbit.

Unpopular opinion time: this is a staggering degree of hubris in the wake of CRS-7 and AMOS-6.

It feels like self-parody.

Timelines: "I'm not the best at this sort of thing." Understatement of the year.

Interesting that he didn't mention the SpaceX satellite project as a possible source of funding, but he did mention his plans to use his personal wealth for this.

Looks like COPVs immersed in those tanks

Carbon fibre tanks?!

Autogenous pressurisation, so I don't think COPVs are needed.

One might suggest a convenient distraction if you wanted to be cynical.

To which there is a famous quotation in answer.

"If you haven't failed, you aren't trying."

Are they planning on evacuating everything from Titusville to Cocoa Beach when they launch this thing? That's like launching 5 Saturn V's all at once! There won't be an unbroken window for miles.

Obviously works for one refueling run -- but Musk said mission profiles could involve several (IIRC, up to five).

This better be called NOVA.
