That makes it look pretty clearly like one of the fuel vessels overpressured and ruptured.


Scott Manley observes the breach was in the cargo section, and not at the PEZ dispenser door. It appeared to split longitudinally. There are header tank downcomer lines that might fit that bill.

The part that I found interesting was ~"Anyone can build a bridge, but it takes an engineer to just barely build a bridge. That's what Starship V2 is, a mass and complexity reduction. Maybe they took away too much."


I'll defer to Scott Manley any day -- this seems like a refinement of what I said.


id be curious what causes the ignition of all the fuel in a breach like this.


It was one of the COPVs (nitrogen, I think).


Thanks for this! here's the live stream from the team: https://youtu.be/WKwWclAKYa0?t=6989


Pro-tip: On YouTube the [.] and [,] keys step individual frames on paused video.


There's a high quality slow motion video available [1] that shows the problem was almost certainly a failed pressure tank, not the engines.

Well that video makes it very clear: the problem is the front fell off, and a bit too enthusiastically.


Is the front supposed to fall off?


Did they use cardboard derivatives?


Let's wait for the engineers to confirm that isn't supposed to happen.


Maybe they should engineer them so that the front doesn't fall off


Unfortunately, that neccesarily increases the risk that the back falls off.


There's something strangely beautiful about this video, similar to the Hindenburg video perhaps, so much detail everywhere


Because the major categories are very hard to cut:

Social Security: 22% Interest on the Debt: 14% Medicaid: 14% Medicare: 14% National Defense: 13%

That's 77% of the budget in those categories.

Everything else is 23%. The Federal deficit is ~25% of receipts.

You could cut each and every function of the government other than the above and still be left with a deficit. And there isn't a lot of room to cut everything else, as they've already been squeezed for decades.


> If I ask ‘ Linux "sort" command line for sorting the third column containing integers’,

Wow, that's actually quite a lot. You can also just say "sort 3rd col nix."


Not sure why this was downvoted, the example actually works.

A lot of my interactions with LLMs are like that and it is impressive how it doesn't care about typos, missed words and context. For regular expressions, language specific idioms, Unix command line gymnastics ("was it -R or -r for this command") merely grunting at the LLM provides not only the exact answer but also context most of the time.

Googling for 4 or 5 different versions of your question and eventually having to wade through 3,000 lines of a web version of a man page is just not my definition of a good time anymore.


The blown up whale in Oregon is sort of like the SR-71 speed readout story. Reposted endlessly, but you just kind of accept it.


There’s film of the whale being blown up. The best part is the sound of whale meat falling from the sky.


you don't have to accept it. it was filled live, and covered expensively.

chunks of whale fell on peoples' cars and required insurance payouts. it is well documented, and unlike the SR-71 -- classified stuff + pilot bravado -- this is just a glorious fuckup


I don’t think GP was questioning the truth of the matter


don't think it was that expensive.


>SR-71 speed readout story

Are you referring to this: https://www.thesr71blackbird.com/Aircraft/Stories/sr-71-blac...

Never heard of it before, but just read it now, and it's a fantastic little story.


I have an autographed copy of Brian Shul's book, which is the origin of it. He used to sell them through his website, though he passed away in 2023:

https://www.nytimes.com/2023/05/30/us/brian-shul-dead.html


The two whales:

- blown up by dynamite

- 393-years old, wandering the ocean since 1627


There are whales, still alive, who existed when Herman Melville first published Moby Dick.

And they still haven't read it.


There is absolutely no chance Starship is developed using steel without Musk. There is absolutely zero chance that Mechazilla would exist without Musk. These are massive elements of the Starship program.

Now, it's true enough that he didn't literally _build_ these things. He is the CEO. Steve Jobs didn't build the iPhone.

But these programs are very obviously shaped by Musk to a large degree.


> no chance Starship is developed using steel without Musk

What are you basing this on? It was carbon fibre or steel. SpaceX tried carbon. The bake was too inconsistent, so they went with steel. This was the stated and obvious design path since Falcon Heavy’s design trajectory plateaued.


Steel is by no means obvious. No one else in the industry uses it. (No one else in the industry uses carbon fiber, either, except things like fairings).

The obvious choice that everyone uses is aluminum, or various alloys, like aluminum-lithium.


I did exactly that, and it was very close to the actual sklearn output.


I tried with alternate values and got the same result - not quite precisely exact, but extremely close values.


It shouldn't be, though. There is way too much democracy in California localities.

There should be no elected school board, transit districts, utility boards, assessors, sheriff, and so much more. No one is properly informed about candidates for these positions.

For that matter, the Board of Supervisors should have no power other than oversight and impeachment. The Mayor should basically be a local dictator, with the power to do anything the State authorizes the municipality to do, at their sole discretion, with the oversight of an elected board.


Americans seem to have a view that if you get a part of an unengaged electorate to mark an x in a box every few years that’s democracy, and more is thus better.

Instead it removes accountability from public servants who can simply hide behind the “elected” excuse.


What terrifies me the most are elections for judges. I am not a legal scholar and I rely upon local bar associations for qualification ratings (and I’m not convinced I made the right call all the time); to my horror I’ve had educated colleagues tell me they just pick cool sounding names.


I do research on all judges before I vote and while I might not know what a good judge is, a bad judge sticks out like a sore thumb.


> oxygenated atmosphere

Of course, the oxygenated atmosphere only exists due to life. Otherwise, it would just rapidly oxidize everything else.


Right, though the evolution of photosynthesis in early anaerobic microorganisms and then their ability to adapt to the oxygen they produced is quite amazing. Oxygen itself is also really fascinating when talking about life because its oxidizing power accelerates the life that makes use of it.

As many experienced gardeners with compost piles know, anaerobic decomposition is much slower and messier than aerobic. Regularly turning the compost pile helps aerate it and makes the aerobic decomposers thrive.


Because molecular oxygen is a highly reactive species, it would also rapidly deplete.

And its reactivity is what makes it so useful for powering advanced life. It's an abundant and highly energetic fuel.

The fossil fuels that gave rise to our industry and innovation are also something we lucked into. The right decomposition environment, eg. in the Carboniferous, made these massive deposits possible. This has greatly accelerated our innovation as a species.
