I don't understand why people are so quick to dismiss SpaceX's ambitions as unrealistic. They were the first to achieve re-usability of the first stage of an orbital class rocket, the first to prove out supersonic retro-propulsion and the first private company to re-fly a spacecraft (the Dragon Capsule). Given that, it seems like they should be given the benefit of the doubt when they say they are going to do somethi…

It's the colonizing Mars part Getting into Mars is solvable technological problem. Colonizing Mars is more economical and sociological problem than technological problem. Everyday living in high-tech place where everything is safety critical (like in a nuclear submarine or ISS) is extremely expensive. Productivity would have to be beyond everything that has ever existed for that becoming possibility. If Elon Musk can…

But we get faster into Mars if we first develop post-scarcity economy here on earth first.

Name that fallacy?

He didn't mention this in the talk, but the story of how SpaceX came to be in the first place is pretty amazing too. He wanted to land a greenhouse on Mars basically as a stunt, to get people interested in Mars again. He wanted to buy surplus Russian ICBMs as a cheap way to launch the thing. After tough negotiations, the Russians basically gave him the middle finger. He basically said, "Fine, I'll build my own rocket…

Oh yeah I read that elsewhere too. Think about how SpaceX would be different if the Russian deal went through..

It is because it will be extremely expensive to do this. Plus there are a ton of issues to be worked out before this is possible. Here is just a small list: - What food will people eat on Mars? - What space suits will they all use? - Who will train all the astronauts to go there? - Who will build the habitats? - Who is building the equipment to make fuel on mars? How much will this cost? This is far from a fully rese…

They already designed the space suits. https://www.theverge.com/2017/8/23/16188658/elon-musk-reveal...

> the SpaceX suits are meant to be worn by astronauts when riding inside the company’s Dragon Capsule

That is not a Mars rated space suit for living and working on Mars. Not even NASA has one ready yet. (They are working on it though)

Remember the fate of Prometheus, who brought fire to mankind. Opposition to creators and innovators is not a new thing.

Just want to point out some misconceptions here: Arguably, the Space Shuttle was the first launch system to reuse the first stage, and the first to prove retro-propulsion landing was the Delta Clipper (on Earth anyways, supersonic retro-propulsion was used on other planetary bodies earlier). First private company to refly a spacecraft was probably SpaceShipOne, although this was suborbital not orbital. Not saying wha…

The difference between a suborbital and an orbital flight is the difference between dropping a basketball, and scoring a three point shot from the other side of the field.

Attaining orbit required 20 times the energy that spaceship one's flight did - it's why landing airplanes is trivial, and landing rockets is so hard.

Musk is truly an inspiration for each one of us. He is the one who dreams big and works even harder. Musk's idea of connecting different parts of Earth using rockets is truly astounding and it would be great if all the government and private agencies come together and try to remove border barriers. It is inevitable that the days of flying cars and jetpack will come very soon and there may be drastic effects if border tension arises. https://www.theverge.com/2017/9/26/16362868/boeing-go-fly-pr...

Last year, it was the Interplanetary Transport System, but now Musk has regressed to using the original, cheeky "code name" BFR, in which the B stands for big, the R stands for rocket, and the F stands for fun. (Not really). I'm always astounded that apparently we still can't say fuck lest some bogeyman (real or imaginary) jump out and make you regret it. It's a fucking word. For fuck's sake. I mean, at the point whe…

F stands for fun. (Not really).

F does stand for fun. A lot of it. It's really down to attitude.

They presumably call it the Big Fucking Rocket at SpaceX. But if Musk says "Big Fucking Rocket" on stage, TV news can't quote him. That's counterproductive to his goals, but using a heavy implication both allows him a broader audience and lets every adult know they've got the 'cheeky' name for it.

It's the Big Falcon Rocket.

Is this an American cultural thing, or are other cultures just as averse to public swearing?

There aren't any real swear words in Japanese. So no it's not just an American thing.

How do you explain this?

I don't understand why civility revolts so many people these days. I tell my son that he can use the F word whenever it makes contextual sense and also doesn't offend other people. For instance, he can use it around me, because to me it's just a word. I don't care. He can use it around his friends when it makes sense. But, he had better not use it around his grandparents. Is it such a bad thing to ty to empathize wit…

It's offensive when journalists feel they need to dance around particular words. It smacks of white knighting in defense of the putatively large group of sensitive Puritans who will take offense at accurately quoting a naughty word. Down the slippery slope to trigger words and microagressions.

Musk is also "dancing around particular words" by using initials.
