The development timeline has been so strange. Falcon 9 was made so quickly compared to Starship. I would have expected a working rocket would have been quick - especially given they have a wealth of experience making the first one. And then I would have expected a protracted period of nailing down the landing and reuse And yet.. just getting this thing to orbit has been seemingly as hard as catching it coming down Do…

Falcon 9 development was announced in 2005, first successful booster landing in 2015.

Starship development time is much harder to pin down and it has changed a lot more. A post-Falcon 9 rocket was announced in 2012, but it was very different (e.g., initially meant to be carbon composite, changed to steel in 2018, went through 3-4 name changes). Starship seems much more exploratory, pushing the boundaries of what has been done in rocketry. Structural material is unusual, fuel is unusual, engines are unusual, using tower to catch rockets is unusual, reentering and reusing booster is unusual, size and weight of rocket and thrust is unsuaul, etc.

Starship's first booster landing (tower catch) was in 2024, so even if we took the start of development as 2012, that is only 2 years later than Falcon 9 for ~same milestone. Falcon 9 of course was flying commercial payloads for some time before booster reuse, which puts it well ahead of Starship on that metric, but I would say SpaceX has been less concerned with getting something to space, they have a reliable solution for that already which is still well ahead of competitors for cost effectiveness, and the company is financially in a much better place than it was when trying to get Falcon 9 working.

Starship development is still working on returning the second stage and orbital refueling, which are beyond Falcon 9's capabilities. It's possible it could have been launching commercial payloads by now if that's what they had concentrated on (without reusing the second stage). They have demonstrated second stage engine re-light and payload deployment, which is basically is needed to put Starlink satellites into orbit.

They're making pretty steady progress. It's off what they had hoped, but so is every rocket company and government rocket project.The rocket is the largest machine ever to fly. It's approaching 3x the size and power of the Saturn V at launch. The engines are like nothing ever made before in terms of power and efficiency. It seems likely to significantly reduce cost per kg to orbit beyond the revolutionary Falcon 9 even if it doesn't hit their goals (which might be unrealistic) of 2 orders of magnitude cheaper, 1 order of magnitude might be possible ($2000/kg -> $200/kg) even without second stage reuse. With orbital refueling it promises to reduce costs of payload to Moon and other planets and outer space. This could spur development of scientific instruments and experiments that are cheaper or more capable (or both), and exploration of space.

I think it's very exciting, not just for the promise of continuing better and cheaper communications for us on earth, but for all the science and exploration it could help to unlock.

It does seem like they're having trouble with re-entry and reusing the second stage. I hope they can work that out. I'm sure they can get it to reenter and land (they essentially already have twice), I'm just quite skeptical of the promise of a few hours reflight turnaround time. I suspect that if that continues to cause them trouble, we're likely to see them start to fly payloads next year without second stage reuse working yet.

Don't discount all of the great engineers at SpaceX just because of their boss, they are still pushing the limits of rocket science every day! And who knows, maybe they're just like us, and they think their boss is a jerk just like any other company employee.

Suppose you have a liberal mindset and work there, you must bend the knee and practice anticipatory obedience, or why else would you tell the world that the rocket will be ”dropping into the Gulf of America?“

While I agree with your general point, as an outsider what struck me the most about Trump ordering the renaming of the Gulf of Mexico as the "Gulf of America" was the pettieness of it, and as such I don't really care.

I mean, I live in Germany now, and the German name for Germany isn't Germany (except when it is because Denglish is surprisingly also used in political posters), and likewise has a different name in French (Allemagne), Dutch (Duitsland), Danish (Tyskland), Polish (Niemcy), and Czech (Německo).

Or how the body of water separating Great Britain from mainland Europe is "The English Channel" or "La Manche" (literally "the sleeve", but also name of a department of Normandy).

I believe a core tenant of the American Way is that we should be able to build great things together with people we disagree with.

Tenet, like the Nolan movie.

I'm saddend by how little I care. I used to follow this quite intensely, and wished space-X the best. But with the owners antics, I just can't get myself to care that much. At the very least, that is sad for all the hardworking people at space-X.

I don't care about the owner too much. He's merely an owner, and apparently not even an expert in the field as to command the direction in crazy ways. As long as Mr Musk continues bringing in money, and allowing the engineers do the right thing, I'm okay with that.

Too bad he's also taking away money from tens of millions of poor americans. I don't even understand. He could have just ... not done that, wouldn't have cost him one cent.

> (Hint: Musk was right and his engineers were wrong. Both times.) This is a really useless statistic. How many times was Musk wrong and his engineers were right? We don't know, we only have those two hand-picked examples from a less than neutral source.

Not even an overall error rate is helpful: it's fine to make a huge number of incorrect guesses when your goal is R&D and the payoff from the few correct guesses covers the expense of the incorrect ones.

For example, engineers also warned the launch pad wasn't suitable for the first test flight, those enineers were correct, it didn't matter as much as it would have for e.g. a Saturn V or a Space Shuttle launch because Starship was (and still is) a test flight of a shockingly cheap unmanned vehicle.

That said, if the people currently raising alarm over Kessler cascade risks are correct, that would be an example of something essentially unsurvivable for Starlink and similar constellations.

Musk gambles when he thinks the expected return is positive; you can do that while winning hardly any bets, let alone loosing hardly any. What you have to avoid fooling yourself over are the odds, the costs, and the rewards, and I do think Musk is fooling himself about political costs if nothing else.

I think the sentiment is more widespread than you think. SpaceX has always succeeded despite Elon’s clown work. I for one would be absolutely humiliated to work for someone like him.

Isaacson isn’t an objective biographer. He needs access to continue pumping out more work, and he won’t get access if he doesn’t show his subject in a positive light.

I don’t doubt these anecdotes that show the guy’s intuition was correct in a few cases. I’d be interested to know when it was wrong.

For example, he had an intuition that his engineers could build full self driving in 12 months 10 years ago. And every 12 months he’d show up promising that it would be ready for real for real in 12 months. Nah bro, he was just lying to pump up the stock price. Yeah, maybe. Or his intuition was just wrong.

He’s exceptionally good at taking credit for work done by others. SpaceX is the classic example, but him playing Path of Exile claiming to have reached the maximum level possible when actually he was taking credit for someone else playing on his behalf is another good example.

Whats the tine frame for starship to be working?

I think it should have landed on the moon one or two years ago? NASA keeps moving its target dates for the Artemis missions every time SpaceX fails to deliver.

Despite Musk's over-optimistic timelines (everywhere not just SpaceX), SpaceX is not the limiting factor for Artemis just because several other critical suppliers (SLS) are even further behind schedule and over budget.

Given their sizes and capabilities, the entire Lunar Gateway space station could be deleted and leave only the lunar-variant Starship upper stage it's supposed to dock with in the same orbit for the crew launch vehicle from Earth to dock to directly instead.

How is he taking money away.
