Hey... it can take only 6 months, if you ship all those millions on a single flight.

It's interesting that Musk claims trips to Mars being cut down to "under a month". That would necessitate some extremely impressive propulsion technology. Not the sort of thing that's likely to be built any time soon, but interesting to hear nontheless.

Engines are not dead weight like the payload, i suppose the math add up somewhere, or so someone think.

On topic, i think that may apply.
Directly or not, the history will judge Musk, not our perceived absurdity of his claims.

Didn't it take the pilgrams 6 months to get to the New World on the Mayflower?

They were an hundred. And most of them died of starvation, cold or diseases. Amerindians provided them food (the famous turkeys).

The first crew towards Mars will probably count 5 or 6 members. Nobody will be there to help them, and there is nothing to hunt or harvest.

So I think that such a comparison is out of perspective and very ideological...

Help them ? The pilgrams thought more likely, to be killed by them. My point was that everything is far away at first.

Definitely out of perspective. Mars doesn't have readily available resources, not without bringing tons of materials (and methods of extracting them locally) with you.

There is some big thinking here, I wonder if practical tech can keep up with it?

I dislike calling anything impossible, but Musk is essentially promising us Mars on a silver platter. Thus far, he has only delivered on a single test docking to the ISS. I remain skeptical.

Can he put a few thousand people on the moon?

We must remember that those who criticised Goddard were under the misconception that rockets cannot function in a vacuum. The writer of the New York Times article was uninformed, whereas those criticising Musk are informed, to varying degrees.

I don't believe he's ever "promised Mars on a silver platter", or indeed, promised anything on a silver platter. At least no more than anyone else in the industry. The fine details, problems and pros and cons of many activities in spaceflight are not often described by people in PR announcements and the like. It's just that it's more noticable in Musk's case because what he's stating is, well... absurd.

Those who can't build rockets criticize the dreams of those who at least try.

He has spoken in the past about nuclear propulsion for interplanetary flight.

Would be more true, if going to Mars would at least be about building rockets. Astronautics is maybe just 10% of the challenge. Logistics, economics and politics are the majority of problems.

I agree, getting them there is only a small part what is required to make it work. He's going to have to have a lot of other companies in with him on it.

Also, how much money can he cut from the plan? If going to the moon NASA style costs already trillions in R&D, how much money could Musk actually save before hitting the bottom? It is not like private spaceflight is much cheaper than public spaceflight, it could even currently still be more expensive.
