dingosity··on SpaceX Starship rocket explodes minutes after launch from Texas
If you cared to, you could download the entire US federal budget, NASA's budget, NASA's contracts with SSL, Boeing, SpaceX, etc. and all the ancillary data regarding milestones and results. You could, if you wanted, download more information that you might ever want about Blue Origin's contracts w/ the federal government. And SpaceX's contracts with the federal government.

Not everything is there, but enough to get a very decent picture of what's going on. Sometimes relevant information takes YEARS to be published.

But it's not easy to find. I've had to directly email people sometimes. Sometimes stuff is classified for no good reason other than someone thought at one point that a particular program was dual-use (commercial/military). Sometimes you DO have to file FOIA agreements.

I'm completely not coming down on anyone for not spending their time doing this. It takes a fair amount of time to piece things together from spreadsheets and contract addenda.

But it is possible.

What SpaceX does is they make it easy to see what they're doing. They upload videos to YouTube and Shotwell speaks at events and conferences from time to time. But you are getting their side of the story. Every now and again Casey Dreier over at the Planetary Society will dig up some previously difficult to find nugget of information about how various programs are being funded and exactly what they're being funded for. But Dreier's job is to focus more on planetary exploration missions rather than aerospace development, so I don't think he's focusing on SpaceX, SLS and Blue Origin.

I believe you underestimate the modal American congress-person and rate-payer.

In congress, maybe about 25% of them can't be bothered to remember what state they're from. They don't really matter as they'll pretty much vote however the last person to talk to them wants them to vote. This is why congressional legislative directors try to schedule appointments immediately before their congress-person votes.

About 10% of congress-people are SUPER sharp and will understand this whole "you have to break eggs to make an omelet" concept. 50% more could be educated. The remainder will act randomly depending on what the internal polling says.

SSL and Boeing and the old school guys know a critical part of their job is to lobby congress-persons and staffers. They're not paying them off, they're just making campaign contributions to ensure they get access to pitch their side of the story.

As for the modal American voter? They don't care about space. They care about whether they're getting a raise next year, the mortgage is paid and inflation doesn't price them out of a good meal every now and again. When they get economic security, THEN they start caring about other things like who goes in what bathroom, why they can't buy TANG or light-bulbs at the grocery store anymore or whether they're getting value for money in their national space program.

My gut feeling after doing polling for a few years is the numbers are about the same: 25% of American voters can't tie their shoe-laces, 10% will understand you sometimes fail when you try to do something innovative and the remainder will need some convincing.

The good news is (effectively) no-one in the US looks at national budgets. Heck, most congressional staffers never read the whole thing, just the bits they're interested in. Many (most?) voters (and congress-persons) look to membership organizations for direction. If someone is a member of the Planetary Society, and they happen to be chatting w/ their elected representative, you can be pretty sure they'll mention how important the space program is. If someone is a member of Drunk Middle-Aged Regressive Science Haters of America, you can probably guess what they think about anything with the pong of science about it. Fortunately, this latter class of Americans usually doesn't know who their congress-person is or that they have a congressional representative.

So... to make an already long post short... I don't think you have to convince EVERYBODY, just the people that matter. The message that "it's okay to fail from time to time as long as you're making substantial forward progress" is something at least half of the people who affect US budget priorities can get their brainstems around.

[And as an aside... having worked with US congress-people in the past, I can report they're frequently much smarter than you give them credit for. And you don't get to be a Legislative Director in a congressional staff without being reasonably sharp. But they do worry about how large donors will respond to their votes. We're entering a phase of debt-ceiling debates. The GOP controls congress at the moment and we'll see a lot of wheeling and/or dealing. It's quite telling to see what each party thinks is important. Biden seems to have invested a small portion of personal reputation in the SLS, probably because of it's history over the Obama administration. Despite it's actual benefits, various GOP members may use that to rail against it (SLS) as a proxy for railing against Biden. (I'm trying to avoid being partisan here, some Dems railed against the Constellation program during the Bush years, so I'm not saying it's ONLY something the GOP does. It's just the typical railing against the other party to try and fire up your base so you don't have to explain why you didn't follow-through on your campaign promises.) But I ramble...]

How would you argue that? I mean, please step me though this argument.
dingosity··on SpaceX Starship rocket explodes minutes after launch from Texas
Elon says Starship launches will get down to $10M per launch within 2-3 years. But he also said we would have our CyberTrucks by now, so... ymmv.

https://www.businessinsider.com/elon-musk-spacex-starship-ro...

By comparison, Falcon Heavy costs about $62M per launch, but Gwynne Shotwell predicted they can shave 40% off that price tag when they start re-using heavies.

https://spacedotbiz.substack.com/p/is-starship-really-going-...

But Elon has supposedly said the TDC (total development cost) of the Starship is projected to be 2-10 billion. [I found this at the Daily Mail website, so take it with as large a grain of salt as you wish.]

https://www.dailymail.co.uk/sciencetech/article-11994755/Wha...

If it costs $10B to build one and $10M per launch and you get 10 launches per vehicle, that's $1.1B per launch if you amortize the development costs. But if it takes $2B to build one and $2M per launch and you get 10 launches, then it's only $220M per launch. But if you build five operational starships that each have 10 launches each, things start to get downright affordable.

So if the question is how much has SpaceX spent on the Starship to date? I don't know that's public info. If the question is how much will they spend on development, the answer is $2B-$10B (though that's from the Daily Mail.) If the question is how much will each launch cost (including amortizing development costs)? It could be as cheap as $42M. Or depending on how much of the $2.9B from NASA they're able to apply to previous development costs... who knows!? They could make $1.6M per launch as long as the GSA doesn't audit them too closely.

There's a myth in US government purchasing that competition drives costs down, and that's probably true for commodities. But Starship class super-heavy-launch vehicles aren't commodities. There's a TREMENDOUS amount of cost (both opportunity cost and dollars) associated with fiscal oversight of large projects. The hope has always been that when Blue Origin built something to compete, it would bring total costs down. I am skeptical.

dingosity··on SpaceX Starship rocket explodes minutes after launch from Texas
Well... the US tax-payer spent $2.9B for a starship or two. Or to be more accurate, there's a contract between NASA and SpaceX to deliver a Lunar Lander Starship variant (NextSTEP-2, Appendix H, Option A.) Last year it was upgraded to Option B which (I think) calls for a beefed-up Starship that can perform multiple lunar missions.

I'm sure they're not just dumping 2.9B in Elon's bank account (I mean... if they did he would just buy back all the Tesla stock) but there are a series of milestones that need to be met for the government to release the next chunk of funds. I don't know if NASA published the exact milestones, but maybe "not exploding on the launch-pad" was enough to release the next block of funds.

dingosity··on SpaceX Starship rocket explodes minutes after launch from Texas
I suspect they were told "if we get off the ground, it's a success." Elon's been saying similar things over the last week.

Adjacent to this discussion is the "All Up Testing" concept from the Saturn era. The conservative testing strategy was to test each component individually, then put them together and test them as a system. All up eschewed this conservative approach, testing everything that was ready. It's only marginally germane to this discussion, but a great historical note since other commenters are comparing the Starship with the Saturn V.

"Abort Once Around" was the name my band used in college for a few weeks before people realized who we were.
dingosity··on SpaceX Starship rocket explodes minutes after launch from Texas
Elon was setting expectations a couple days ago when he said "Let's just not explode on the launch pad" or somesuch. In that sense, mission definitely accomplished. "Massive" success? Not sure I would go that far, but success of a massive project? Absolutely. It would have been nice to see the mission hit all it's objectives, but I'm sure they got quite a bit of data and operational experience.

What would be a failure is if the next one has the same problem.

dingosity··on SpaceX Starship rocket explodes minutes after launch from Texas
I think they're using the Starship to go from Gateway Station to lunar surface. So you could add an escape system, but where would you escape to?

They also had a lot more money (adjusted for inflation) and didn't have to worry about updating their code to the latest version of python.

It's also possible one of the TLS endpoints in the rotation didn't get the cert update when everyone else did and was serving an expired cert. Then the Reddit SREs noticed it and fixed it before too many people complained.

What about women who don't have female reproductive organs, like those with Androgen Insensitivity or are post-hysterectomy? What about men who are post-orchidectomy? Are they not men? And if Androgen Insensitive women are not women, does that mean they're men? That will probably come as a great surprise to them.
dingosity··on Gezellig – a word that encompasses the heart of Dutch Culture
But we (English speakers) are not above ripping off untranslatable words from other languages. At work I used to talk about fingerspitzengefühl and schwerpunkt; we didn't even bother trying to translate them to English. And everyone I know knows about schadenfreude and zeitgeist and "je ne sais quoi."

Maybe we do have translations for them. Maybe the English word for schadenfreude is "schadenfreude." (But yes, if you want to say I'm cheating, that's fine.)

dingosity··on How do you take notes in your important meetings?
I once tried to take notes on a laptop, but gave up on that years ago. I now take notes on paper. I listen for a few categories of things: todo's, discoveries, open questions and next steps (which I guess are like todo's, but with more commitment from a specific person.)

I tend to avoid writing everything down and focus on the things I know I might forget (or their might be dispute about later, which is why I ALWAYS write down next steps / todos.

I think if you try to write EVERYTHING down, you'll be too focused on writing down what you just heard, you sometimes miss the next thing that someone says or don't have time to think about your response (if any.)

Some meetings related to open source projects I've been involved on are done over zoom (or skype in the old days) -- most people gave permission to be recorded for those meetings, so it's easy to go back and replay something you might have missed. So you can focus on writing down only the highlights (like decisions, open questions, next steps) and for details like IP Addresses, specific versions, hostnames, etc. you can just go back and find it. But I think most corporations I've encountered really don't want recordings of internal meetings in case there's a law suit.

dingosity··on The Cybertruck is years behind schedule, so Tesla is launching a $30 beer
But Mr. Musk is playing 11th dimensional chess that the rest of us are incapable of understanding. But more seriously, there are reasons they didn't start on it until now, maybe those reasons will persist and they'll get past the sunk cost fallacy and just decide to cancel it.

Even then, what's the chance that Tesla will remember who gave them a $99 deposit. SpaceX completely forgot about how I gave them $599 for a downlink terminal. I had to email them scans of my credit card bills to convince them to look for their records of the transaction so they could refund the charge on my credit card. (And even then, they only refunded $500 or the $599 I spent.)

But I'm grousing about SpaceX, I'm sure Tesla has a better AR/AP/CS system.

dingosity··on The Cybertruck is years behind schedule, so Tesla is launching a $30 beer
I probably should have noted it. It's a safe assumption that any comment I make about Tesla is at least somewhat sarcastic.

It is technically equivalent because if you buy shares you increase the value of an elastic commodity that directly benefits the company when they issue more shares (or offer for sale shares which have been authorized but unissued.)
dingosity··on The Cybertruck is years behind schedule, so Tesla is launching a $30 beer
So... the strategy is to not appeal to older buyers who have money and instead court younger buyers who can't afford your vehicle so they're "locked in" to a brand they can't purchase. Interesting.
