If each one can be used 10 times that's 10,000 flights. With 6 refueling each that's 1,666 flights to Mars, each carrying 50 people. More than 80,000 people on Mars.
And these are pesimitic numbers. More likely Starship will be cheaper (~40 million each) and be used more than 10X.

You know how with a water hose that you can make the water come out faster if you partially cover the hose end with your thumb? Same basic principle with rocket nozzles. However, counter-intuitively if you constrict the fluid flow to the point where the fluid moves as fast as sound can travel through it, then constricting the flow even further wouldn't make it go faster. Instead, after the point in the flow where it travels at sonic speeds (called the throat) the flow area is expanded which makes it go even faster.

I would think it was more a matter of practicality. A big point about androgynous docking ports is that if you have gendered docking, capsule vs station, then you can't dock two capsules together. Just the chance that there may be an emergency that needs capsule-to-capsule docking makes it a good thing to have.
I think I also read that they had an extra airlock in the dock because Apollo used oxygen and Soyuz used plain air.

If all spaceflight from 1957 to 2029 is a 24cm (9 and half inch) line, Apollo 11 happened at 4cm (1 and half inch) and for the next 20 cm (8 inches) to 2029, no human spaceflight beyond Earth has occurred yet.

There has been roughly five times the amount of time from Sputnik to the Apollo missions and no major crewed spaceflight between celestial bodies has occurred since then DESPITE von Braun planning a crewed flight (a whole fleet!) to Mars and other plans for a venus flyby.

It is at this point a certain extreme cold anger wells inside at you against the the crippled Space Shuttle program and against what would be the US's major space competitors failing to inspire another major space race.

Nothing fundamental prevents other rocket companies from surpassing SpaceX except their own laziness/institutional inertia/lack of ambition. SpaceX's monopoly is more like the monopolies of the mid industrial era where seemingly every year a new company would invent a superior product and monopolize the market and then collapse under the pressure of a superior competitor who would dominate for a short time in turn. The early lamp oil industry is a great example of this. I'd label these "natural" monopolies, IE they will arise given no interference from the outside, as technology and economic strategy changes over time. SpaceX will probably end up forming this kind of monopoly eventually.
Boing! and the other oldspace companies are what I'd call an "artificial" monopoly, in which the corporation(s) has colluded with either other corporations or the government (or both) to form an unbreakable monopoly which is immune to normal market pressures by using strategies like government bailouts, no-bid contracting, cost-plus contracting, etc.

A "natural" monopoly is the sign of technological and market progress, it means that people are creating things so good so fast that the leaps of technology can regularly catapult one company far ahead of it's competitors. On the other hand, "artificial" monopolies are a sign of a sickened economic system which allows excessive government intervention to produce active state/corporate collusion to stifle productivity for the personal gain of a few.

Right, well like I said, I don't know too much about Amazon specifically, I was just addressing the idea that there might be some kind of hypocrisy from Elon claiming Amazon to be a monopoly that needs to be broken. Generally speaking monopolies that need breaking are artificial ones which are too well dug in to collapse of their own accord.

>>12019665
Amazon breaks the market and competition to keep its monopoly. If a small business shows up and threatens one of amazons products, amazon will lower their prices and operate at a loss until the small business goes under, then raise their prices back up.
They also buy out other businesses and throw them on a shelf to rot to save themselves.
There is also the lobbying and political bullshit to get what they want.
Satellite internet is the next huge cash generator. Years ago, you had to apply to the FCC for the space to launch satellites and make the constellation in a set range of frequencies. Musk applied, got accepted, and has been working towards his goal. Jeff Who didn't go for it because he didn't think it would work. After seeing SpaceXs model, he tried to apply to make his own constellation, but missed the deadline to apply. So he was declined, and it was all public. So now, after some behind-the-scenes "negotiations" Jeff Who suddenly has the green light to start launching sats to make his own system.

Not necessarily, the ship itself would be heavier if it had to carry the same weight in hydrogen for example, because LH2 requires much larger, more heavily insulated tanks. To get the same delta-V though yes, you'd need a heavier ship if you wanted it to run off water alone. Also yes, spacecraft will be more likely to just use water for drinking, bathing, and shielding.

The F-1 and every major engine family tied to 1960s NASA spaceflight in the Von Brain era was basically the space version of WWII wunderwaffe shit like the Me-163 or the Me-262 where nobody cared about reliably or time between major overhauls so long as it hit the right insane performance thresholds.

The problem is that that attitude persisted within rocketry post-Apollo, spurred on by aerospace contractors wanting to make big bucks on shit that needed to be rebuilt for each new launch (or essentially rebuilt in the case of the SSME), which in turn has fucked access to space since we're still stuck in 1942-era jet engines when it comes to rocket reliability.

I always assumed that nasa was the very best that there was, the most advanced technology invented by geniuses. That the high cost was the result of the need of perfection in spaceflight and that precision engineering went into every decision. The only things that gave me an inkling that things were wrong was sitting in school and seeing the poster of American rockets, with the tiny V-2 compared to the Redstone, Saturn V, and then shuttle. But when I saw that the shuttle was the newest one yet not the biggest or most capable I knew something was wrong, along with never returning to the moon. I also ate the bait 100% when Neil Armstrong took a giant shit on SpaceX at the congressional hearing. I figured that the government had the resources to do space right, private companies were to motivated by greed and they'd never get it done. It wasn't until Elon got results better than the last few decades that spoke for themselves that I realized the truth and how I had things backwards.

Bro, just imagine when they start flying those rockets and Muellers team have exponentially more data to work with so they can further ootimise their engines and tanks, like they did with the Merlin? 400 bar seems probable by the time the start flying the cargo version.

SH/SS is surely going to be 130m + tall. Bezos might aswell give up on the commercial market. I dont know how anyone is going to catch up to the Elon/Mueller/Shotwell super team.

>> No.12020769

>>12020732
Alright, but if they do crack the 350 bar mark with longer firing times, and reusability by the time SS/SH is operational at around 2023, doesnt that still change the game? They are already nipping at the toes of Blue Origins Be4, despite significantly being lighter. Elon thinks they can optimise for a better thrust/weight ratio than the king of efficiency, the Merlin engine. Surely this is huge news, and shows that the Raptor has a much higher petformance ceiling than what they initially believed.

I want to see how a F9 upper stage running a single vacuum Raptor would perform too.

>> No.12021095

>>12020892
Well, it develops significantly more than twice the thrust of the Merlin 1D, and has 380s ISP compared to the Merlin's 348s. If it's ISP were to increase comensurate to chamber pressure, the increase of 10% would give it somewhere in the ballpark of 418s, I'd be surprised though if it actually managed to crack 400s though, but even that puts it closer to the efficiency of the Hydromeme rockets. Of course, it might crack that without needing the uprating, because so far we're getting the ISP of the sea-level optimized Raptor. For example, look at the SL Merlin 1D versus the VAC Merlin 1D, the expansion bell gives the vacuum Merlin 38s more ISP compared to it's SL counterpart.
For the sake of fun, let's assume Raptor 1B reaches 400s of ISP with it's increased chamber pressures, if a vacuum expansion bell is added and it confers the same 12.2% increase in ISP as the VAC Merlin 1D's bell, then the actual ISP of the uprated VAC Raptor should be 448.8s or only about 4s off the ISP of the RS-25. Even if we were to half the gains of that expansion bell, it would make VAC Raptor's ISP around 424, solidly in the same playing field as the LOX/LH2 engines, but with much smaller tankage, and much higher TWR.

Math tells you something about how it might fly brainlet. If my assumptions are relatively close to reality in the end it would be comparable in thrust, nearly comparable in ISP to the RS-25, but the engines themselves will be 30% or more lighter, it's tanks could be probably close to half the size to store the same mass of propellant.

The artemis program is relatively recent and the first SLS probably requires a lot more development. I'd be willing to bet production will be ramped up a lot after Artemis I, so that they can justify using the SLS at least through the rest of the Artemis program.
