This is a jobs program which happens to produce rockets. The rockets are not the key objective, the jobs are.

Playing devil's advocate here: wouldn't "preserve institutional knowledge about building rockets" also be it's goal?

> preserve institutional knowledge about building rockets

No it would be "preserve institutional knowledge about building OUTDATED rockets"

If you are a tech company are you going to run your own outdated servers at 10x the cost because you would like to preserve institutional knowledge about running outdated hardware ?

Your argument would be correct if the cost difference was not that huge, the fact that it is so huge indicated that the tech they are using is very very outdated. No point in preserving anything about it.

I don't understand - what is the motivation here? The article is a little short, and it gives good insight into just how expensive this is (compared to other similarly classed potential space purchases). However, what I am failing to grasp is... why? Why spend so much when these other options are available? Surely not ignorance. Is it malice? corruption? Someone's ego?

This is a jobs program which happens to produce rockets. The rockets are not the key objective, the jobs are.

But do we really need those C*O jobs and increased shareholder value? Probably keeping many of rocket science jobs could have been cheaper for taxpayers. But no one cares about that today, our children will be paying our debt, not us.

Space isn’t easy. Going to the moon is significantly harder than LEO. I don’t think one can claim functional and performance equivalence between SLS to FH. https://youtu.be/Y81vx__JngY Now, if the argument is: Why go to the moon? Well, that’s a different conversation.

I had little hope for Bridenstine when he got the position, but I must say that I've been impressed time and again. That video was absolutely terrific.

"Outdated" also means well-researched, well-tested, with very little unknown unknowns. I do not mean "safer", necessarily - but the data about how safe they are is much more reliable.

As a startup CTO, I will think twice about using the freshest framework or programming language, which is sexy and cool - just because I haven't seen enough people use it long enough yet. I will build a hobby project with it and love it, but or a small product that is allowed to fail, but I will not start an important new product with something like that.

The motivation as proposed was to reuse already existing and certified STS (Space Shuttle) components in the next generation rockets, to reduce costs. The Falcon rocket family did not exist at the time that the SLS was proposed and green-lit.

Falcon Heavy didn't exist, but the Falcon family certainly did (and had flown).

The cloud hardware metaphor is a good one.

Preserving knowledge is easy and cheap.

Preserving capability (that is to say, people and companies with knowledge and ability to use it) is not.

To use the metaphor, a huge part of the military procurement budget is dedicated to continue building, deploying, and operating on-prem servers.

Not because it's more efficient, but because at an international level, having a cloud provider (or in this case Russia or China) tell you "No" when you ask to renew or expand, is unacceptable.

Unlike tech, machine shops filled with trained people can't be provisioned with a click...

It's not C-level jobs, it's thousands of normal blue collar and white collar aerospace jobs across multiple states for many years.

The purpose of the space program isn't to explore space, it's to consume federal funds, accruing influence and kickback contributions to the politicians who arrange it.

It's important you understand this primary purpose if you want to understand what happens at NASA.

If you are a space program supporter who is okay with the situation as long as NASA is getting money, then you are the reason they can get away with this. Thanks a lot.

Richard Feynman was pulled in to investigate the space shuttle challenger disaster. He refused to sign the report unless his findings were included. They were eventually included as an appendix, which is well worth reading.

There is a section on the main engines (you can search down to the SSME section)

As far as I can tell, this is the space industry's "Wile E. Coyote" moment[1]. A long one at that.

This kind of largely unquestioned cost structure ("cost plus" contracts[2][3]) has been going on for such a long time now that nobody in that part of the industry has really accepted that the party is over.

And of course industry players don't actually have to accept that the party is over as long as government pays those old-style prices, which have been outrageous for some time and have only gone up. (They seem to have gone up even more egregiously recently, which might be an indication that industry is actually very well aware that the game is up and is trying to rake in as much as possible while they still can).

And yes, there are justifications, some of which may also be reasons (jobs, know-how, whatever ...), but I am sure that inertia is a huge part of this. If this were being decided from scratch, I doubt the outcome would be the same.

And yes, the current industry is almost certainly doomed. Yes, Falcon and Falcon Heavy are already dramatically cheaper. But Starship, if it works, is something else entirely. Game over.

I did a back-of-the-envelope calculation that showed a fleet of 10 Starships, if reused as planned, having such an increase of capacity over what we have now that the current yearly launch capacity of the entire world becomes a footnote, a few percent of what those Starships will be able to haul into orbit by themselves.

And they're planning to mass-produce these.

Game over.
