The price per kg to orbit based on total program cost has dropped a lot.
As for why SpaceX is charging $50m instead of $10m I think it's partly that it costs more than $10m for a launch and partly that they are a for profit company. Why would anyone come in 80% cheaper than the competetion when you can be 20% cheaper and still get all the contracts?

We don't know because the books aren't public.

What we don't know is SpaceX has gotten ~$8b government funding and put ~581,000 kg into orbit.
$13769 per kg, not including launch costs

We also know the shuttle got ~$209b government funding, I'm having a real hard time finding a source for total payload to orbit.
If you can find a source of total shuttle payload to orbit we'll have something to work with.

while musk is indeed the reddit of entrepreneurs and some of "his" projects are more dreamy than practical i cannot understand that he's getting shit on for a 50 year late revival of space missions. we either become space faring or extinct. i'd choose someone who does little to anything about it over a cynical hater who's technically correct about insignificant parts. we have a goal on the horizon and we need to start walking at some point. who's gonna do it instead? china? russia? europe? just one reuse of a used rocket is a step forward in my book, and there's literally no downside in doing this. if it fails we're at the same point of regular rockets. if we succeed, we can use a rocket again.

According to SpaceX, "Low pressure in the fuel header tank during the landing burn led to high touchdown velocity resulting in a hard (and exciting!) landing."

In simpler terms, SN8’s fuel header tank experienced low pressure as the rocket descended, which caused the rocket to land too quickly and therefore too hard, which caused the explosion.

Why was SN8 venting pressure while this was happening?

1. I'm not sure how you didn't get it, he goes through and lists benefits from NASA we've gained and why space travel IS worth investing in.
2. Even if it fails now doesn't matter, we will eventually be able to sustain a colony. It'll be hard and could potentially be centuries from now, but it's not impossible.
3. I literally brought up starlink, and Elon definitely has more plans other than being an ISP in space. The technologies being created right now will eventually be reused in future endeavors, and will impact the consumer market.
4. Improves the economy by creating job opportunities, allowing a lot of profits are waiting to be made. Commercial tourism, asteroid mining, funding from governments isn't a money sink if it will end up creating $$$.
5. Oh yea let's all just work till our deaths because fuck imagination and optimism. Let me work my shitty day job and only focus on the important things in life.

tfw astronauts come back effectively crippled after like, a month in low g. You gonna do 1month roatations with 6month travel times? Those aren't permanent bases either. Now, I have always conceded that a chink hell colony is possible this way lol, but this isn't what you want.

Isn't that a bit too much? It may be that you got interested in space because SpaceX made it fashionable and that's not bad, but that's not always the case. We do need as many private companies as possible to compete with each other but that's it. Glorifying a single company won't get you to Mars or the Moon sooner.

not only does musk not have friction stir welding know-how to build solid boosters.
https://youtu.be/o0fG_lnVhHw?t=2470
he doesn't even employ resistance-welding know-how to build his fuel tanks which is an accepted industry standard for aircraft fuselage.
https://www.hu-steel.com/m/news355_579.html
>The form of weldment joints for electric resistance welding is limited, but the components suitable for electric resistance welding are still very extensive, for example, aircraft fuselage, automobile body, bicycle rim, various anchor chains, washing machines, refrigerator casings, and the like.

>If you look at the properties of a high-quality 304L stainless steel, at cryogenic temperatures the strength is boosted by 50 percent.

You are aware that steel has a fatigue limit, unlike aircraft bodies which are made of aluminium right? This means that so long as the stress on those welds is kept under a certain limit, they can perform identical maneuvers indefinitely with no fatigue or damage to the metal. This is one of the MAIN REASONS they chose steel in the first place you absolute fucking midwit.

It doesn't have to be you fucking idiot. So long as you can reasonably determine the forces across specific areas and maintain the weld quality to the standard you want then it is very easy to stay below the fatigue limit. But please, keep on spamming barely relevant links that showed up in the top 10 results of your google search. I'm sure you are more knowledgeable than the engineers at SpaceX, lmao...

no need to stick with the industry standard and keep joints and seams to an absolute minimum with automated friction stir welding and resistance welding and end up with practically perfect joins when you can have dozens of bum crack tradies using welders on a design with an over the top number of joins.

try to explain that the less joins, the less likely to go wrong and they bang on and on about all we have to do is pilot the craft like a bunch of soft footed pansies and it will never develop any fatigue.

I kid you not, they advocate more joins, sloppy human welding and an overall pansy spaceship that will break apart if some teenager colonist stole the keys and took it for a joyride!!
