One hull crack located in ISS, another one suspected

The ISS and all spacecraft that dock with it run at 1 atm. Which is nearly all currently flying spacecraft. (And probably Shenzhou does too, since it's basically a Soyuz.)
I'm surprised. I read somewhere that Apollo etc. were at fractions of an atm.
Apollo-era spacecraft were at about a third of an atmosphere when in space.

What is the difference between "Carbon" and "Carbon-Carbon"? It seems incongruous.
I think this is this: https://en.wikipedia.org/wiki/Reinforced_carbon%E2%80%93carb... which is carbon-fiber in graphite, apparently, so the name is apt in that it's a composite of two different forms of carbon with different properties.
Yes. It's a heterogeneous allotrope made from typically pyrolyzing the matrix, followed by slowly decomposing Acetylene inside the porous structure until the porosity is gone.
Other ways are to just infuse the porous matrix with more resin, before pyrolyzing again. Then loop a (few) dozen times.

No. Communism and planned economy are not capable of producing consumer goods. Source: I actually lived in the USSR.
Anecdotal evidence isn’t evidence. They’re capable, what they lack(ed) is the creativity to do so.
They weren’t even capable to FEED and clothe their people. The queues and lack of everything was legendary.
Source: another anecdotal evidence, my youth lived under the horror of communism.

While that is true, the USSR produced a better military and more, higher quality consumer goods than most nations of it's size. That said, it is certain that the soviet system was suboptimal in a great many ways. But, crucially to the fact at hands, 1960s' USSR produced better rockets to send people to the ISS, at a lower cost, than 2021's USA, so there something beyond the free market in this particular case.
Government contracting is not indicative of a free market.
I'm sorry, what else are you suggesting? That we let the free market figure out by itself how to maintain the ISS without signing any government contract?
Also, Falcon 9 wasn't the product of a government contract.

Brings my mind to the ultimate acronym: PCMCIA People Can't Memorize Computer Industry Acronyms
TLA and FLA are my favorites
(should be) obligatory (now get off my lawngrange)

This reminds me of one of my favorite Futurama lines as their ship is going underwater: "Dear lord! That's over 150 atm of pressure!" "How many atmospheres can the ship withstand?" "We'll, it's a spaceship, so I'd say anywhere between 0 and 1." https://youtu.be/Ewu-zHH5Qwg
Space craft are run at much less than 1 atm.
That doesn't change the fact that the external pressure they are designed for is 0 to 1.

> The first big space push was mostly a political pissing match (i.e. not really driven by doing it for its own sake). My understanding is that the Defense Department was interested in human manned spy satellites liked the planned Manned Orbital Laboratory early on, but that automation progressed to the point where it was preferable. I think that's one thing people miss when they talk about lack of progress in space.…
10 years ago the consensus--scientists, engineers, etc--was that self-driving cars would be ubiquitous or on the cusp of ubiquity today. That same common but woefully mistaken wisdom is also behind the preference for remote space exploration and exploitation. We clearly have issues with underestimating the complexity of these engineering problems and overestimating the pace of technological progress. I'd also argue,…

This is only true if you were sampling the people trying to build them (which is mostly what the popular press did). Really there wasn't anything like consensus, but there was a lot of optimism.

The US free economy produced a better military and plenty of high quality consumer goods.
I’m not arguing the US isn’t a better system. I’m saying had the USSR decided to allocate its resources towards consumer goods, it’s ridiculous to think they couldn’t have had a large industry.
It's ridiculous to think that that could produce anything good for consumers. The system just didn't work towards that goal. You can't design a fashionable piece of clothing if you have a 5 year plan imposed on you.

Going to space is only a secondary goal for SLS though. Keeping a bunch of people in politically influential states and congressional districts employed is the primary goal and it's succeeding at that.
Government spending "creating jobs" is a lot like a business plan where you pay people to buy your products, or a car that makes its own fuel.
Not quite. Under certain conditions (high marginal propensity to consume, etc.) the "multiplier" can be > 1, and then your stimulus really creates value.
