Source? Several raptors have been fired for long duration and even multiple times. If the chambers would melt that should not be possible. Of course RUDs of engines happened but they were the exception and not the norm.

Elon himself said this was one of the major remaining problems in last night’s presentation.

But I think what he means is that currently the chamber gets to much damage to be full reusable on a daily bases over a long period of time, not that it doesn't work at all.

>This engine makes everything else possible. I have seen lot of tweets ( from highly intelligent people and engineers ) suggesting Starship is not possible. Raptor 2 is not possible. But now it seems it really is coming. It is easy to fault him for robotaxi and FSD, which a lot of people do. But sometimes he really does the impossible.

Seriously, it's only a matter of time before Elon Musk announces the space elevator.

Space elevator on earth doesn't really make much sense. On Mars maybe, it will happen on Mars way before it happens on earth.

how many people would have a $50,000 expense set their retirement savings back at last a couple years, if not bankrupt them? none of these people are building a rocket company in their lives.

$400 =/= $50000 Also Jeff Bezos was born to a high school attending mom who worked as a secretary and went to night school after she quickly became a single mom - he built a rocket company

Good lord. Jeff Bezos worked in finance and had a six figure job lined up if Amazon failed.

I can’t figure out if this is an HN thing, but this cult mentality of “anyone can do it” needs to die out.

I’m unsure there’s much to discuss in that specific regard? If you believe in cheap heavy lift and humans colonizing Mars, you agree this project has merit (and the costs and human effort involved reasonable). If you don’t, you see this project as superfluous and wasteful. Is that interpretation inaccurate? It’s somewhat, but not entirely, binary. From the presentation, development costs will be 5-10% of the Saturn V…

What if I believe in government run Mars colonies, but don't believe in private ones like one run as Musk's empire? Am I not allowed a nuanced opinion?

I honestly don't understand. If your point is someone who has only worked jobs for minimum wage is never going to suddenly start a rocket company I'd say you're correct. Especially if someone built or found their safety net on their own, I don't think we should begrudge them having it.

How do you think this works? Do you think 'anyone can do it' means winning the lottery? It means working really hard, getting lucky along the way, and being smart - that likely means getting into finance if it's the 80's and early 90's and tech if it's late nineties and aughts. It doesn't happen overnight.

The reality is, though, that you don't have to be born to millionaires to be one of the richest people in the world.

The Raptor 2 engine is just an absurd. The original specs were already kind of insane. But Raptor 2 is an monster. They really pushed already significantly into a second generation design before first flight. Raptor 2 is not just a slight upgrade, its a huge upgrade. If it can actually launch multiple times a day without any refurbishment, it will simply totally break space travel as we have known it. This engine mak…

My theory is that they aim to disrupt Earth travel (airlines). Elon pointed out that the reliability of Starship would exceed that of commercial airplanes, and the fuel costs are not that different than, say, a 747. Fewer moving parts than an airplane, less human costs, order of magnitude faster...

>reliability of Starship would exceed that of commercial airplanes

I don't think he said that. Maybe you're thinking of:

>44:31 "so the interesting thing is that the

capital efficiency of

of a rocket is is is much better than

the capital efficiency of a plane for

long distance flights"

I'm not sure that this will ever be viable for the general population. Think about the acceleration at launch and reentry. It's more an amusement park experience than travel by car, ship or plane. There will be people mentally and physically fit for that (past some age and before another one) and people that will never be. Other problems like cost, time from home to spaceport and boarding can be fixed or be irrelevan…

Man If I could fly (rocket?) to AUS from the UK in a handful of hours I'd be all over that vs. the 24+ hour flights + connections. Sure it doesn't make sense for all routes but for super long distance I can see it being competitive for some section of the market.

That is false. The only companies he has objected to are ULA which was getting a 1 billion dollar a year retainer (effectively a subsidy) from the US government, which is rightfully bad, and Blue Origin which basically wan…

That isn't correct. He has spoken out against EV subsidies recently.

> but that hasn't stopped him from trying to stop others from benefiting from the same. That's complete nonsense. Unlike others SpaceX has never really attack other space companies. Musk has been supportive of other space companies. SpaceX busted open the establishment in both DoD and NASA so the contracts are fairly competent, and everybody coming in the industry benefits from that. SpaceX just recently lost a contr…

In a recent WSJ he, Musk, spoke out against government subsidies. I don't mind such subsidies but I do mind when people who benefit from government help want to stop others from doing the same.

Weed use makes no difference as to his leadership abilities or trustworthiness

It does in the eyes of the US military which is the customer in this case.
