It was designed early on in SpaceX's history before Tesla had blown up in value and musk was superrich so It has a practical design and realistic use case the one other non spacex launch would be the Artemis test launch using the SLS, which is literally 'wasn't that big fuel tank they launched with the shuttle cool looking? what if we just launched that ' literally same rockets, same thiol solid rocket boosters for 23 billion dollars it has launched once and there's as many spare RS-25 engines as there are planned launches before retiring the project (loving two lol) we cant build more, ofc quote:Previously known as the Space Shuttle main engine (SSME), it was the reusable main engine developed by Rocketdyne for the now-retired Space Shuttle. Remaining RS-25D engines are planned for use on early Space Launch System rocket launches after which an expendable version, RS-25E will be developed for foll same company that built the F-1 rockets on the Saturn V

SpaceX is already a well-run organization, you can leave most of it in place. Sure it would work better under a superior economic system (especially one with a better education system) but it's perfectly functional right now. It's one of the most impressive space organizations in the world and not merely the best private spaceflight organization. BitcoinRockefeller posted:Wow, so much data! We learned that a flame diverter trench is absolutely necessary and that flying concrete bits are bad for rockets. Honestly this was already known. There is a serious problem where people are so blinded by hi-tech gizmos and rapid operations that they forget about solid proven technology like just digging a trench. gradenko_2000 posted:You ivory tower intellectuals must not lose touch with the world of industrial growth and hard currency. It is all very well and good to pursue these high-minded scientific theories, but research grants are expensive. You must justify your existence by providing not only knowledge but concrete and profitable applications as well. Technological advance is an inherently iterative process. One does not simply take sand from the beach and produce a space probe. We use crude tools to fashion better tools, and then our better tools to fashion more precise tools, and so on. Each minor refinement is a step in the process, and all of the steps must be taken.

There are two kinds of scientific progress: the methodical experimentation and categorization which gradually extend the boundaries of knowledge, and the revolutionary leap of genius which redefines and transcends those boundaries. Acknowledging our debt to the former, we yearn, nonetheless, for the latter.

Or you could just have the government pay the scientists so we don't need them tethered to any billionaire self-stroking or any profitability concerns. I hear in a couple years and however many billion more dollars we might even get back to the kinds of moon missions we did in the early 70s. I honestly never expected them to get that far.

FirstnameLastname posted:the one other non spacex launch would be the Artemis test launch using the SLS, which is literally 'wasn't that big fuel tank they launched with the shuttle cool looking? what if we just launched that ' The SLS is literally the same tech as the space shuttle. Same solid-fuel boosters, same fuel tank, same liquid-fuel rocket engine. The SLS was designed by congress to keep those same factories open and running. The difference being that the space shuttle landed with those RS-25 engines and reused them while the SLS will just drop them into the sea. The space shuttle was always kind of a dumb idea. Every pound launched to orbit is very expensive and the space shuttle was very heavy, each pound of weight for the space shuttle was a pound of payload that couldn't be launched on that mission. Compare that to the Falcon 9, which reuses the first (bottom) stage instead. The first stage is both the heaviest (and very costly) stage and the part that goes the least "distance" and goes at the slowest speed (in rocket terms). The fact that the first stage is moving so "slow" also makes it the easiest to recover The Soviet space shuttle Buran was still conceptually kind of a dumb idea, but it made a number of improvements. It was launched on an Energia rocket that could launch other missions as well, so the Buran didn't need the massive engines that the US shuttle had (and had to drag all the way into orbit). This also removed the need for massive amounts of cryogenic fuel to flow sideways through the shuttle body and into the engine. The ice formed on these fuel lines is what caused the Challenger disaster. Edit: At one point there was another US concept for a shuttle replacement. It was called the Shuttle-C. It was uncrewed and those big engines at the bottom would drop off in a "boat tail" and be recovered. This allowed the engines to be reused and saved all the fuel it would take to get them all the way into orbit. BearsBearsBears has issued a correction as of 05:12 on Dec 27, 2023 |

The estimates range from roughly 1 in 100 to 1 in 100,000. The higher figures come from the working engineers, and the very low figures from management. The final catastrophic failure rate of the space shuttle was 2 in 135, pretty drat close to the engineers' rough estimates. Fun Fact: Big Bird from Sesame Street was originally supposed to be on the final flight of the Challenger. He was scrubbed from the mission because he was too large for the seats and spacesuit. He was replaced with the teacher Christa McAuliffe, a civilian specialist who would conduct educational lessons for children from space and demonstrate how safe and routine spaceflight now was. Overall, it's probably for the best that millions of children didn't wind up watching Big Bird explode on live tv. BearsBearsBears has issued a correction as of 06:16 on Dec 27, 2023 |

galagazombie posted:I’m also stupid (or at least ignorant of the topic) so can someone explain this to me? They want to seize Russian assets, but like what assets? And what are the expected effects? Western financialization since the end of the cold war has left the US, UK, Germany, etc. in a position where they own huge swathes of world economic activity but most of that is the paper plane spreadsheet activity of finance capital. That activity is contingent on being the world's banking, investment, and financial broker. Using the economic high-ground of finance capital to seize paper assets from Russia doesn't actually hurt their ability to wage war in the short term since all the physical industries of war continue to operate, but it does create new and powerful incentives for everybody to build their own financial apparatus outside the control of the West. It's ultimately just an extension of banking logic - the reason you put your money in a bank is because you have some reason to believe you'll be able to get it back later, with some interest. As soon as the bank starts playing by different rules and deciding who can get their money back out, people start looking for the exits. If you are an elite literally anywhere outside NATO, you're now looking at this action and going "well guess I shouldn't put my money or investments in that system since they're going to steal it from me if I make them mad." AFAICT the reason they're doing this is because it plays well domestically in the US and they're having trouble getting the money-printer to work the way it used to so they're looking for some paper dollars to provide the fig leaf necessary to transfer more lockheed and general dynamics poo poo to blow up in Ukraine.
