Now that we are up to a launch per week, two fully reusable launch platforms are about to enter service and the martian/lunar transportation system is about to start its flight tests its time to have a thread that discusses space transportation infrastructure and transportation vehicles.>since no one created a new thread you're stuck with this picture
The 5 stages of Kessler Syndrome denial:1. It's a hoax, Kessler? You serious dude? If you're worried about that you don't know SHIT about science, like read the prospectus bro, it says right there it's not a problem, they wouldn't LIE in a PROSPECTUS would they?2. Ok it exists but it's not because of THIS megalomaniac rapey rape bro managed, blockchain NFT SPAC IOT tensorflow RNN deep learning space launch startup, actually it's CHOINA and the slant-eyed CHOINAMAN3. Ok it exists and sure, maybe in fact it's entirely because of this MRRBMBNSITRDLSLS, but actually it's NBD, one day it will just disappear4. Ok look, it might be a big deal and it's not going away but the cure is worse than the disease, like broooo what if we have to make our commodities futures bets the normal way instead of using a plague of private football satellites to gather real time intel on crop dusters and oil tanks, broooo this is class warfare also don't forget CHOINA5.

>>1798249What's wrong about Venture Star?
>>1798249Linear aerospace engines were a tremendous technological breakthrough that were abandoned before they could see their true potential.Liquid hydrogen remains an absolute bitch to contain in propellant tanks but liquid methane largely eliminates these issues while burning almost as cleanly as hydrogen. Methane also has the unique perk of being able to share a bulkhead with an adjacent liquid oxygen tank.Propane may have similar benefits but only if burned oxidizer-rich.
>>1798840*linear aerospikefuck autocorrect
Linear aerospike may very well be better, but I don't think anyone wants to risk sinking billions of dollars in R&D into them to find out. So long as we stick with cylindrical vehicles round engines will continue to dominate. Easier to make a good reliable engine and make lots of copies of it.Though I believe 1 startup is planning to use round aerospikes on their rocket.
>https://twitter.com/blueorigin/status/1524386115511324672BE-4 looking pretty good.
>>1798444Single stage.There is no reasons to go single stage on Earth due to rocket Single stage = 1% payload.Double stage = 4% payloadThis means single stage is 4 times larger and expensive comparing to double stage.If even possible. Because single stage designs requires very high mass effeciency, if it is slightly less than ideal you may end with no payload at all, very little margin.
Saw a good pasta on some other board the other day on how the lunar gateway/lunar exploration will be the starting point for humans to settle the entire local system thru the use of ISRU, orbital fuel depots, lagrange points and novel hybrid fusion afterburner drives - And ultimately massive fucking space stations and cities on mars and what have you Didn't save said pasta unfortunately but it was a neat summary on what the rest of this century might have in store yet if we don't end up glassing each other before that point
God i hope we see warp drives come to fruition A wormhole drive would be fine, too
>>1798909That's why you slap some boosters on the side.
>>1798444>>1798840>linear aerospikewere garbage dead end tech. Venturestar was a waste of thought hours
>>1798914If it wasn't the gateway they have planned I would agree
>>1798983>roscosmosi hope someone else has plans to replace that module
Axiom ordered a bunch of Canadarm 3 parts for their station modules. The power data grapple fixtures are backwards compatible with the ISS arm. They will likely eventually buy the same arm the lunar gateway is getting.
>>1798973The whole reason for the idea is to have an engine that can maintain thrust efficiency from sea level all the way up to orbit. Conventional bell-nozzle engines cannot do that.
>>1799040Its literally just a soyuz port, its unnecessary

Fucking astra acting like its something
The first weather forecast for the #AtlasV #Starliner #OFT2 mission was issued by the @SLDelta45 this morning. The outlook for Thursday's 6:54pmEDT (2254 UTC) launch from Cape Canaveral is 70% GO
Mega bay coming along, will accomodate 10-12 workstations rather than 2-3 of high bay. Also modestly taller (30')Will use ullage gas for small maneuvers rather than hot gas thrusters. Elon realized this was the way to go during a previous Tim Dodd interview.B7 is better and simpler than B4 and B5. Upgraded grid fins and chines.The chines are 120° offset (aimed more down than flat). It helps balance the booster in reentry so it comes in flatter, and increases the ability to capture the air and get more resistance. These chines are primitive, will be improvedwhy using grid fins rather than something more traditional? For now, F9 experience. Also, good stability of performance in sub through hypersonic regimes. Low motor power requirements, especially compared to flaps. But perhaps could do better in future. Also, even with grid fins, may get away with just 2? Not more than 3 in the long run, with the third small, if they do stick with grid fins.Back in early F9 days they tried doing boostback with no grid fins? Too unstable. But you don't need BIG control surfaces to compensate.There's a dispenser door on S24. Elon: it's not going to blow anyone's mind. Tim: you'd be surprised. Elon: If the mechanisms inside jam up, that'll be pretty embarrassing. Joe: It's like an industrial pallet-stacker.Next launch will be full orbital, not this quasi-orbital plan from earlier… but there was like a 30m/s difference so eh.Not high confidence that first flight will work.The tiles will expand to fill in the gaps. Shingling them would be excessively complicated… they think.
>>1800475They learned everything they could from the sub-orbital hops they've already done. S20 is done.The starship orbital stack is going to come off the pad very fast. Should have thrust-to-weight ratio of 1.4+ at takeoff. Reusable vehicles care more about fuel efficiency and therefore T/W than expendables because fuel is a bigger part of operational cost.If you think in terms of cost per ton of payload to orbit, you can't cheat. ISP, T/W are nice but only if they help bring down cost to orbit (or to surface of Mars / Moon / whatever), per payload ton.Current Mars missions have a cost/ton of payload of $1B. To make a Martian city, have to bring that < $100k/t, or 10 000 times better.How will you catch ship with arms? Very similar to booster. Need shield tiles to go over 180° so catch points will have to pop out or reach around. Can you catch with the flaps, aiming them forward enough? That is not a problem you want to try to solve!Forward flaps will work, but have lots of room for optimization. They are the wrong size, the wrong position, and the wrong location (not sure what the distinction between those last two is). They bug him. Could maybe get rid of them.They will build a factory to replace the tents.
Back-to-back Falcon 9 launches of Starlink within 24 hours, completing SpaceX's 19th and 20th launches of the year
>>1799045Seems like a waste of money
>>1798852Aerospikes are sexy but they aren't worth it.
2 months away bros can you feel it.
>>1800475>Next launch will be full orbital, not this quasi-orbital plan from earlierHe said its still a Hawaii splashdown without a full orbit, but is calling it orbital. Its orbital velocity but not circularized.
>>1800486Yeah but it isn't a hop, its basically an orbital flight.
3 days this piece is gonna launch. Gotta wonder if it'll work. I hate boeing but I want it to work.
>>1800491Its wrirdly aesthetic, if it wasn't a POS it would be great
>>1800492Also imagine being the first astronauts on this thing. It would be stressful as all hell
>>1800496Then again I would hope all these delays have made them perfect it but you never know.
Compared to the dragon its scary However.
>>1800490Basically but not pedantically.
Falcon9 is still having its performance improved by SpaceX as they continue their launch cadence.>We’ve seen them recently launching 53 satellites to trajectories and orbits where in previous occasions, the rocket could only launch 46 or 47 satellites.>William Gerstenmaier, SpaceX’s Vice President of Build and Flight Reliability, already claimed during the post-Flight Readiness Review conference for Axiom-1 that thrust profile optimizations for Starlink flights had been implemented to improve performance of the rocket.>It is understood that SpaceX is also improving the performance of the rocket by changing certain timings during flight like igniting the MVac engine a few seconds earlier than on other missions or separating the fairing closer to stage separation to shed dead weight earlier in the flight.>Additionally, SpaceX is loading propellants on the rocket at slightly lower temperatures than usual in order to pack more of them into the tanks and increase the amount of Starlink satellites the Falcon 9 can put into orbit.
>>1800502Right but no real reason to be pendantic.
Honestly we are so close to the Moon and Mars, we have every design already made and in testing. We will see them both this decade.
The funny thing about Starliner is that its launch rocket is being retired. I'm assuming that Boeing purchased all the rockets necessary to complete their contract with NASA. But for any other launches Vulcan will need to be human rated first. Maybe they can barter with Amazon for some of the legacy rockets they bought for Kuiper.
>>1799353That's why I opted to use strap-on boosters for my design.
>>1800527Even more retarded
>>1800518Boeing isn't going to plan for any more than what is contracted. I'm sure they'll crew rate vulcan but man do i wish NASA forced it onto a falcon9
>>1800509>Raptor 2 engine x33I'm getting somewhat concerning N1 vibes here. Those engines are fucking great, but that is 33 engines worth of points of failure. Glad it is being used for the unmanned launch elements at least.
>>1800539The N1 didn't fail because of the number of engines you brainlet. God damn thats angry boomer tier logic.
My favorite part of launch statistics like this is that it records based on country except for the US which it records by individual company. Absolutely Mogged.

NS-21 is targeting liftoff from Launch Site One on Friday, May 20. The launch window opens at 8:30 a.m. CT / 13:30 UTC. Learn more about the crew and the symbols embedded in the #NS21 mission patch: https://blueorigin.com/news/new-shepard-ns-21-mission-announcement
>>1800509If the starship orbital velocity test flight is successful then how quickly would the starship start flying regular missions?
>>1800564>>1800565>The patch concept came from Astronaut Evan Dick, who said reaching space in the crew capsule on NS-19 felt like climbing above the surface of the ocean after a lifetime of living below the surface. Additionally, several of the NS-21 astronauts have journeyed to the depths of the oceans and are passionate about the Earth’s waters. The five stars around the crew capsule represent Blue Origin’s fifth human flight.The arrow symbolizes Blue Origin’s astronaut pin to celebrate Evan Dick’s second flight on New Shepard, in addition to the thin line within the number ‘2.’ Evan is also a passionate sailor and diver.>The lighting bolt represents Katya Echazarreta’s passion for electricity and her mission to increase representation of women and minorities in STEM.The circle represents Hamish Harding’s accomplishment of setting the global circumnavigation record by plane. In 2021, he dived the Challenger Deep, the deepest point in the world, with Victor Vescovo in a two-person submarine.>The diamond with the circle represents Brazil’s flag in honor of Victor Correa Hespanha's heritage.The water drop honors Jaison Robinson’s passion for diving, water polo, and climbing the tallest waterfall in the world.>The triangle represents a mountain, paying homage to Victor Vescovo’s feat climbing the world’s seven summits. In 2020, he became the first person to repeatedly dive Challenger Deep (now 12 times) and is the first person to visit the deepest point in the world’s five oceans.
>>1800569>>1800565>>1800564The patch looks cool but holy fuck talk about adding self importance to something that isn't important.
>>1800539they couldn't synchronize all the engines back then. Now we have computers that could easily do that
>>1800566Its going to be rapidly evolving for a few years yet. But the prototypes starting with the first orbital attempt will be carrying Starlink sats since SpaceX is willing to risk losing them.
>>1800541Reducing points of failure isn't "boomer tier logic", it is optimisation. I hope it fucking works, and I'm sure it probably will end up fine, I just get a little apprehensive when I see it. Not trying to tear down your gay space communism fantasies, just hope the cunts don't blow apart a complex biting off more than they could chew.>>1800572This does give me more hope that there are least won't be a sync/guidance failure, but I still have reservations over the mechanical parts running fine/qa working out. I know that SX wrecked a lot of Falcons getting the platform downpat and are now reaping the rewards, but I also don't think there will be much patience for the same occurring with Starship HLS.
>>1800574>Reducing points of failure isn't "boomer tier logicMore engines doesn't always mean more points of failure considering how simple theyve made the plumbing and other mechanisms. Also it gives redundancy for failure to occur. >boomer tier logicI said angry boomer as in angry astronaut you newfag. >I just get a little apprehensive when I see it.And that matters why? Do you get apprehensive of the falcon9? How about the delta 2? >just hope the cunts don't blow apart a complex biting off more than they could chew.You are insanely naive of current tech capabilities. This isnt the 1960s, stop acting like we face the same challenges.> Not trying to tear down your gay space communism fantasiesCommunism is for faggots, expanding the white race and creating a more stable future for our people is the goal.
>>1800578Sorry anon, I have no idea who angry astronaut is, I presume either a youtuber or twitter user? I am always somewhat apprehensive about new platforms, and the real concern here is the inevitable one of scale (a Falcon I blowing up and an HLS blowing up are very different things and you know it). Also, sorry to spoil it for you, but as long as space exploration is defined by the governments and billionaires of the world, you are going to get gay space communism. Wish it didn't have to be this way, but that is where we are. This isn't the 1960s, stop acting like we have remotely the same cultural standing.I want to see this succeed, but I don't understand the cultish "DON'T YOU DARE FUCKING DISPLAY ANY SORT OF HESITATION" that has grown since people convinced themselves that CEOs funding engineers in a way that governments should have for decades now are personal celebrity geniuses comparable to a modern Brunel.
>>1800574>but I still have reservations over the mechanical parts running fine/qa working outThe ascent phase of every flight theyve had with the raptor has been nominal.>I know that SX wrecked a lot of Falcons getting the platform downpat and are now reaping the rewards, but I also don't think there will be much patience for the same occurring with Starship HLS.Everything they learned from that testing they will apply to the starship and they have had 157 flights worth of experience to improve upon their operation. Starship isn't starting from scratch it is evolutionary, the flight testing should reflect that. >but I also don't think there will be much patience for the same occurring with Starship HLS.Starship will have so many flights under its belt before HLS and in reality they don't even need to have reusability figured out for HLS to work.
>>1800582You see, that is stuff I am largely on the same page with you on. Apprehension now will undoubtedly be relieved by the time we are actually at HLS launch, although I will openly admit to the fact I will feel concerns until the first staging of HLS from Superheavy.
>>1800579Yes he is a youtuber that always talks about the N1 when it comes to the starship. Hes a boomer so hes called the angry boomer here.> I am always somewhat apprehensive about new platforms, and the real concern here is the inevitable one of scale (a Falcon I blowing up and an HLS blowing up are very different things and you know it)Yes but this isn't oldspace, spacex will launch this platform frequntly and will test it exhaustively. Iterative testing and thorough live testing is so much better that simulation and sign offs. Also no they are not very different things, HLS refers to a flapless upper stage (pic related) but I assume you are talking about superheavy and superheavy is only a big risk on ascent which really isn't where the challenge is for spacex, upon landing the superheavy will have very little fuel and won't really be a huge risk.>as long as space exploration is defined by the governments and billionaires of the worldAviation started the same way, so did every technology. You are retarded if you think it means anything. >standing.I want to see this succeed, but I don't understand the cultish "DON'T YOU DARE FUCKING DISPLAY ANY SORT OF HESITATION" Because the hesitation is coming from ignorant people like you who are worried about things that aren't an issue. Had you stated some realistic concerns I wouldn't have jumped on your comment. In other words lurk moar. >that CEOs funding engineers in a way that governments should have for decades now are personal celebrity geniuses comparable to a modern Brunel.Elon is the lead engineer, he is in the weeds with the design and he works insane hours for this goal. SpaceX basically saved the US space program from becoming defunct and that makes people supportive. On top of that spacex is laser focused on a mars colony which people have only dreamed about, also since its a private entity it cannot be stopped by the petty whims of the politicians.
>>1800579>>1800590Also Musk is much more impactful and influential than Brunel and I would argue his engineering philosophy is better as well.
>>1800584Its called starship, HLS is only the lunar landers they are building for NASA, those landers will not be part of the test flights the starship will be. >although I will openly admit to the fact I will feel concerns until the first staging of HLS from Superheavy.That is fine but your apprehension shouldn't be on things like the number of engines. Also there will be years of launches and tests by the time the test HLS lands on the moon.
>>1800595Pic related is the falcon heavy which also utilizes numerous engines on launch.
Not quite related but don't forget the lunar eclipse is tonight.
>The Expedition 67 crew is ramping up for the arrival of Boeing’s new Starliner crew ship due to launch next week to the International Space Station. Meanwhile, the orbital residents continued their ongoing human research, cleaned spacesuits, and maintained lab hardware.>NASA Flight Engineers Kjell Lindgren and Bob Hines trained on Wednesday for next week’s launch and docking of the Starliner spacecraft on Boeing’s Orbital Flight Test-2 (OFT-2). Both astronauts spent part of the day familiarizing themselves with the OFT-2 mission and Boeing’s Starliner vehicle systems. The duo also reviewed Starliner’s post-docking procedures including leak and pressurization checks, entering the vehicle, and cargo operations.>Boeing rolled out its Starliner vehicle to the United Launch Alliance (ULA) launch facility at Cape Canaveral Space Force Station in Florida on Tuesday. It was attached atop the Atlas-V rocket from ULA later that day. The Starliner crew ship and its rocket now stand vertical at the launch pad counting down to a liftoff targeted for 6:54 p.m. EDT on May 19. The unpiloted Starliner vehicle will automatically dock to the Harmony module’s forward port about 24 hours later where it will stay for cargo and test operations for five to 10 days.
>https://twitter.com/visegrad24/status/1525909526968401921Starlink is working well in Ukraine. Imagine how it'll work once they have thousands more sats.
For the first time ever, scientists from UF grew plants in lunar soil! The ability to grow plants in space is essential to enabling longer term space exploration and this research will be key as we prepare to return to the Moon with Artemis.
>>1800605Space makes many things difficult but one thing easy. To vacuum seal sample, close bag in a vacuum.
>>1800605I guess that means you don't have to 100% rely on hydroponics but is there any real significance to this?
>>1800592>Also Musk is much more impactful and influential than BrunelYou see that is where you lost me completely. To say that he might go on to be more influential than Brunel, hell, if he gets us to Mars sometime before 2040 then he will earn that title, but at the moment he is a man who has become exceptionally good at getting government agencies to fund his eccentricities. Not even knocking him for that, it is a fucking good grift and I respect him for it, especially if it bears fruit in time. That being said, at this point we have the body of Brunel's life of work to compare to Musk's work to date, and I consider the Great Western to have done more for humanity than getting some astronauts to the ISS with a method other than Soyuz and shitting a ton of cubesats into the orbital neighbourhood. Here's hoping your boy comes through in the end.
>>1800550SN24 is really looking good now
>>1800634The tiny cargo door reminds me more of a pizza oven or disc shooter than a pez dispenser.
>>1800614It basically proves that plants can grow anywhere, duh Hence the universe is teeming with life
>>1800615Winning contracts is not the same as a grift. Also the government gave more money to the competing but worse performing companies like boeing and lockheed for the same contract programs. The government is saving billions of dollars from using SpaceX rockets and they get a superior product. >especially if it bears fruit in timeIt already has, the falcon 9 and dragon have done numerous flights to the ISS have launched so many government satellites like the landsat 9 and have given the us full control over their launches again. NASA would be using the soyuz to get their astronauts to space still and would be paying through the nose to get anemic payloads to space. >That being said, at this point we have the body of Brunel's life of work to compare to Musk's work to date, and I consider the Great Western to have done more for humanity than getting some astronauts to the ISS with a method other than Soyuz and shitting a ton of cubesats into the orbital neighbourhoodMusk founded X.com which became PayPal and PayPal was crucial to the rise of ecommerce. So already he was deeply involved in a company that impacted the lives of the average person around the world. Then you have Tesla which absolutely revolutionized the auto industry, has pushed the world to adopting EVs and has forced their competitors to focus on automation. SpaceX also has revolutionized their industry with the falcon 9 gorcing the industry to turn towards reusability and play catchup against a decade old launch platform. Currently China, Germany, France, the UK, Spain, the ESA, Japan, and Russia are all pursuing reusable rockets similar to the Falcon9. Also Relativity Space, Blue Origin, Arianespace, ULA, and Rocketlab are pursuing similar concepts. The falcon9 and dragon capsule like I stated previously have given the US self reliance for spaceflight again and have given them insane launch cadence capabilities at a very low cost per lb to orbit.
>>1800653Then there's starlink which is already serving thousands of rural customers and changing where people are required to live, it is also being utilized by multiple airlines changing how inflight service is provided and it is being used tohelp both the Ukrainian military and civilians while in an active warzone. On top of all that SpaceX has the starship program which has already been chosen as the HLS for NASA. That has entirely changed the scope, timeline and goals of the Artemis program. It has also lit a fire under the ass of the SLS team and has forced the government to take the program seriously. So even if Elon stopped right now he would have revolutionized 3 industries, kickstarted the defunct space program, and impacted the lives of millions. But he is not done, his mars colony plan is well underway and with it so many other space based capabilities/the course of humanity, FSD is going to change automation in so many aspects of our lives not just cars, starlink is going to connect most of the world while changing the rural/city dynamic, his purchase of twitter may keep us from tyranny and the boring company and neuralink may change the average person's QoL as well. He is Christopher Columbus mixed with a Rockefeller/Carnegie industrial titan, he is a brilliant engineer like Brunel and he is impacting the future socially. I would argue noone is comparable to him

The experiment doesn't really prove much other than random dust can be used as a root support structure. People that do hydroponics use rockwool insultation to act as a root support which is similar but with better porosity.

When will the United Kingdom have a domestic launch capability?
>>1795769The US department of commerce is currently trying to >uhhh make policybut unfortunately they are slow and retarded. They were supposed to have figured it out like 3 years ago because the space force doesn't want to keep giving SpaceX free data and special gibs.

The Vulcan centaur is their first one, it is not flying yet, its powerful but its not even focused on reusability. Like I said when they have a product they will get respect. >SKA have issues with starlink among others.The vast majority of astronomical research programs at optical wavelengths only begin well after twilight. Same is true for ametuer observation which makes starlink not really a problem. The IAU Center for the Protection of the Dark and Quiet Sky From Satellite Constellation Interference has also been created and should mitigate even more of the issues involved with emerging satellites. They have concerns about mega constellations which is why they are in direct communication with SpaceX and Oneweb and Amazon. SKAO was also just approved which means its not a problem they believe they cannot tackle. >Performancemarket is chasing PorscheThe Model S outperforms the Taycan, the model 3 has yet to be beaten as a full package and topgear, motortrend, caranddriver, topspeed and carmax will all tell you the same. To argue otherwise is disingenuous. >why do they still not manufacture a competitor to the Leaf?Because they are already affordable. New-vehicle average transaction prices (ATPs) increased to $46,526 in April 2022, according to new data released by Kelley Blue Book. The model 3 is $46,990, that may be not affordable to you and I but that puts it in the affordable range

WDR delays CRS launch.
China launched 55x in 2021. It's reasonably to assume they'll double that by 2031, and if they've figured out reusable rockets by 2035 in the same class as Starship/SuperHeavy, then you can reasonably double that again. So ~2-225 launches a year. More importantly though, in context, I don't think China considers SpaceX & America as one item and instead compares itself more to NASA and legacy providers the world over, and in context of that, that statement could be true.SpaceX is in a class of its own and trying to compare yourself to them, when you're about a decade behind the curve is silly.

I'm going to make a rough calculation for how much money will have to be spent on a Mars colony before it is self-sufficient. Of course it is impossible to predict the future, but we can make some reasonable guesses and come up with a ballpark figure.Population: The population starts at zero. Musk claims you need 1 million people to become self sufficient, so we will agree with that claim. To make math easy, I will say the same number of people get added to the colony every year (or synod..doesn't matter for the math). This means that the average population from when the colony starts until when the colony is self-sufficient is 500,000 people. Claiming the number grows at a constant rate is of course wrong. That isn't how populations work. Maybe later I'll get into the more complicated math to refine this estimate.Time: Musk claims there will be a million people by 2050. I don't think anyone (even Musk) believes him. I'm going to claim it will take 100 years to go from zero to 1 million people on Mars. Later I can see how much changing this number impacts the final cost.Cost: I will assume a ticket to Mars is $100,000. I will assume living on Mars costs 4 times more than the average cost of living in the United States. Why 4 times more? Because houses have to be strong pressure vessels, the air has to be made and cleaned continuously, the water has to be mined and recycled, the food has to be grown inside large pressure vessels, going outside to do anything requires very expensive and technical equipment, and of course all of these houses and equipment have to be built new because none of it exists right now. Some random website claimed the average cost of living for a single person is US$38,266 so we will claim on Mars it is US$153,000.
>>1808590Self-sufficiency: When the first colonists arrive, they will have to import everything with them. But after 99 years the colony will be almost self-sufficient, so not very much will have to be imported. After 100 years, nothing will have to be imported because the colony will be self-sufficient. So in the first year, the entire $153,000 per person has to be imported. After 100 years $0 has to be imported. So on average during the first 100 years, US$76,500 has to be imported per person per year. Now just to be clear, if the living expense is $153,000 per person, and if on average $76,500 has to be imported, that means we assume on average $76,500 of value is being created by the colonists to support each colonists each year. The first year they haven't started working yet so they are creating $0 value. At the end of 100 years they are fully self-sufficient so they are creating $153,000 of value per person. So on average the are creating $76,500 worth of stuff per person in the colony to support colonists.So now we can calculate how much money has to be spent on imports before the Mars colony is self-sufficient.For 100 years, we have an average of 500,000 people costing $76,500 in imports per person per year.Total cost = 100 x 500,000 x 76500 = US$3.8 trillionSo in the first 100 years, the colonists have to import US$3.8 trillion worth of equipment. But during the same time, they are creating US$3.8 trillion in value in the colony to support colonists.
>>1808591It costs a total of $7.6 trillion to run the colony for the first 100 years. Half of that value is created by the colonists, half of that value is imported.We can add the cost of the tickets to get there. Let's assume we ship 1 million people to Mars, and the ticket price is $100,000. That comes out to $100 billion. Because the ticket is bought on Earth with Earth money it counts as an import. That raises the total imports from $3.8 trillion to $3.9 trillion. It is interesting to note that the cost of getting there is a pretty insignificant fraction of the cost (about 2.6%).So it costs $3.9 trillion worth of imports and flights for a Mars colony to become self-sufficient.Just to be clear, this doesn't include the work that the Martians do on Mars to support themselves. We are assuming all of that is free (or paid for with MarsBucks). The $3.9 trillion is just the cost of imports. The imports have to be paid for with Earth currency (let's assume US$, but it could just as easily be Euros or Yen or whatever).Where does the Mars colony get $3.9 trillion in Earth currency?Where does the money come from?
>>1808593Charity: We can assume some really rich people are going to fund the colony....or maybe some governments. Let's say Elon Musk funded this? Right now Musk has $218 billion. We would need 18 Elon Musk's to have enough money. But of course to get $218 billion Musk would actually have to sell his companies, and if shareholders are in charge of SpaceX instead of Musk you can probably kiss any Mars colony goodbye. We want Musk to stay in control of SpaceX, which means he has less money available to buy stuff for colonists. We could hope to get funding from NASA. Let's say NASA gives 10% of their budget to the Mars colony for the next 100 years. That would be $240 billion. So between NASA and Musk, we've got less than 12% of the money we need. And thinking we would get anywhere close to 10% of NASA's budget for 100 years is incredibly wishful thinking. They didn't even fund the end of the Apollo program and fly their last couple missions even though they'd already built the hardware. So we can not depend on charity.Tourism: This is another pipe dream. Round trips to Mars take at least a year. Almost no one on the planet takes year long vacations. And the ultra-rich aren't going to spend large amounts money to sit in a stainless steel can for many months when they can be yachting in the Mediterranean or do any number of other luxury vacations. I'm not saying there will be no tourists. But the number of tourists will never be high enough to provide a significant fraction of the necessary money.
>>1808595The colonists: When the colonists move to Mars, they will have Earth money. All of their Earth money will be used to buy stuff to bring with them. This all counts as imports for the Mars colony. So any money the colonists have before they move to Mars counts towards the $3.9 trillion. So let's say we have 2 million colonists (because we are talking about a 100 year time-span to get to 1 million on Mars, all of the ones we send at the beginning will be dead before 100 years is up, if birth rates are low we have to send a lot more than 1 million to get to 1 million at the end of 100 years). If 2 million colonists provide the $3.9 trillion, that is US$1.95 million for each colonist. If each colonist pays almost $2 million for the right to live on Mars, then the colonists will be providing enough money to fund the colony until it is self sufficient.
>>1808596SummarySo a Mars colony needs to create $3.8 trillion worth of machines, habitats, food, oxygen, water, spacesuits to survive the first 100 years. They also have to create $3.9 trillion worth of stuff to sell in the first 100 years so they can buy imports. But they will only be able to create $3.5 trillion worth of stuff total. The only other viable way to raise the necessary money for imports is if every single colonist brings $2 million with them to the colony. There is still the shortfall between the $3.8 trillion worth of products they have to make themselves, and the $3.5 trillion that they are capable of making, but these numbers are close, so we'll call it good.DiscussionSo why is this so hard? Based on my numbers, it is basically impossible.What it comes down to is the cost of living vs the productivity of each colonist. I assumed that the cost of living is 4 times higher than the average cost of living in the United States. And I assumed the colonists would be as productive as the average person in Silicon Valley. If these two numbers are correct, the colony is doomed to fail (or the price to join the colony has to be $2 million).
>>1808597Is my cost of living estimate reasonable? Right now, we don't pay anything for air. We pay next to nothing for water. Our food is grown very cheaply in huge fields with very little equipment. Most of the cost of the infrastructure all around us has already been paid for by previous generations. Our houses are made out of flimsy materials because they don't have to be strong. Walking outside doesn't require any special equipment. The costs for designing new things (like cars) are spread over many millions or even billions of people. Shipping costs for supplies are quite low.On Mars, we will have to process our air to make it safe. We will have to mine water ice with heavy machinery, and do a much better job recycling than any Earth water treatment plant. Our food will have to be grown inside strong buildings in soil (or hydroponic systems) that don't exist yet. All of the infrastructure will have to be built from scratch, none of it exists yet. Habitats will have to be much stronger than houses to withstand air pressure. Any work outside has to be done in complex clothing that is basically its own mini spaceship. And the cost of designing new stuff (we will have to design a lot of new stuff!) is only spread over less than 1 million people. Shipping costs for supplies are very high.So I think saying the cost of living on Mars is 4 times the cost of living in the US is actually very generous. It is likely the cost of living on Mars will be much higher.Is my estimate for productivity reasonable? Will people on Mars be more productive than people in Silicon Valley. It isn't likely. There is a "city" effect where productivity increases in large populations. It just becomes easier to share ideas, start new projects, bump into someone at the coffee shop who is the perfect person to help your team. For a long time a Mars colony will be a small town, and even once it gets up to 1 million people it is still a lot smaller than Silicon Valley.
>>1808598Being so far away from the global supply chain means if you are prototyping a new product, and you need some specific part, you can't just order it on Amazon and have it there the next day, or order 1000 of them on alibaba and have it there in a month. You will either have to wait months or years for it to ship from Earth, or you will have to manufacture it yourself. Being required to manufacture all uncommon parts when prototyping or building specialized equipment will slow down the process and decrease productivity. The same is true with spare parts for fixing broken equipment.Being far away from Earth's internet will slow down productivity. I'm sure there will be a mirror of almost all websites located on Mars, but that mirror can't possibly be complete, and there will be times when people have to wait for the round-trip communication delay to get information. That will make them less productive.Any work that has to be done outside will be much more difficult. That will make people less productive.So saying the Mars colonists would be as productive as workers in Silicon Valley was being generous. It is unlikely colonists will be able to be that productive.ConclusionAgain, based on my assumptions of cost to live on Mars and productivity of Martian colonists, it will be pretty close to impossible for a Mars colony to exist unless each colonist pays $2 million to the colony for the right to move there.And my assumptions for cost of living and productivity were generous to the colony.
>>1808599Now, eventually we'll have self-replicating machines. That blows away the "productivity" number and a Mars colony will be no problem. But until then a Mars colony seems impossible, and it seems Musk should be focusing on self-replicating machines instead of Starship because the transportation issue is actually small in comparison.So assuming we want a colony to get started in the near future (before self replicating machines), how can it happen? What are the steps we need to take to get from here to there?Future work The main thing that could be improved in my calculations is changing from linear population growth and linear "self-sufficiency growth" to more realistic scenarios. But I'm pretty sure that doing that will result in the beginning of the colonization period becoming much more difficult and things getting easier near the 100 year self-sufficiency goal.
NASA issues a statement on why the CRS-25 Cargo Dragon launch has been postponed. An issue during prop loading of the Dragon.
>>1808583>>1808581Kek absolutely delusional. Its not reasonable to assume that will double especially with the challenges china is facing this decade. >and if they've figured out reusable rockets by 2035 in the same class as Starship/SuperHeavyExactly how are they going to do that outside of espionage. Right now they're using soviet technology andthe starship/superheavy is much more advanced then we even realize, they aren't getting that in 12 years, especially not with the trouble they are facing internally. >More importantly though, in context, I don't think China considers SpaceX & America as one item and instead compares itself more to NASA and legacy providers the world over, and in context of that, that statement could be true.So ignore the absolutely monumental lead your competition has and then you can pretend you are leading? Its ridiculous, NASA has the launch vehicles of SpaceX contracted for their missions, they are one and the same.>SpaceX is in a class of its own and trying to compare yourself to them, when you're about a decade behind the curve is silly.Far more than a decade>build a nuclear powered space shuttle. Lol, lmao, lol
SPX 25 patch
I still don't get how they wanna deploy Starlinks from S24.Elon kept saying during the interview that it doesn't require much dV to raise perigee but the sats still can't do that in a single orbit.So you need to raise perigee, deploy and then lower it again
https://blogs.nasa.gov/spacestation/2022/06/06/dragon-mission-on-hold-as-astronauts-conduct-eye-exams-spacesuit-work/>NASA and SpaceX are standing down from this week’s Falcon 9 launch of the CRS-25 cargo mission to the International Space Station. Officials from NASA and SpaceX met today to discuss an issue identified over the weekend and the best path forward.>During propellant loading of the Dragon spacecraft, elevated vapor readings of mono-methyl hydrazine (MMH) were measured in an isolated region of the Draco thruster propulsion system. The propellant and oxidizer have been offloaded from that region to support further inspections and testing. Once the exact source of the elevated readings is identified and cause is determined, the joint NASA and SpaceX teams will determine and announce a new target launch date.it's over
>Our Mars rover mission was suspended because of the Ukraine war: here’s what we’re hoping for nexthttps://www.thespacereview.com/article/4398/1>On March 17, the European Space Agency’s council and member states decided to suspend our mission. We won’t know for sure what happens next until a study by ESA and industry partners reports back in July, but there are causes for optimism.>Now, ESA is looking at options. Given that continuing with Russia in 2024 is most unlikely, the main possibilities are either ESA going it alone, or teaming up with a partner such as NASA. ESA’s new Ariane 6 rocket, which is nearly ready, could help launch the rover, as could a SpaceX rocket. For the lander and heaters, ESA would need to develop these alone or in collaboration with NASA, by adapting existing technology.>It could therefore take time. What’s more, because of the way the planets orbit the Sun, there are opportunities for launches to Mars only every two years: in 2024, 2026, and so on. My expectation is that 2028 is most likely for our mission, but it will require hard work. The positive thing is that ESA and the member states are still keen to go ahead, and we are eagerly looking forward to the launch whenever that will be.pathetic
>>1808569Hopefully the SMART reuse system works so that they just reuse the same 4 engines over and over again, they won't even need Blue Origin after the next 3 are delievered!All seriousness I'm excited about Vulcan. Yeah, SpaceX's rockets are awesome but competition is always healthy in the market and frankly SMART sounds (to my uneducated mind) more robust than ~~suicide burns~~ hoverslams. With SpaceX focusing on Starship, maybe ULA will corner the LEO market with Vulcan?
>>1808632>>1808627>>1808612I expect nothing less
Well bros is june the month we launch?

>>1798973>linear aerospike>badLinear aerospike is what they use on their current SSTO spacecraft that have been secret since the 80s. The secret isn't that we stopped going into space, but its so cheap and affordable the economy / public wouldn't be able to process the fact we have a moon and mars base already.
>>1802819Hopefully it wont leak piss behind wall panels like Dragon.It's cool we have SpaceX but don't be fooled by their sleek looks. A company so focused on image and appearances with somewhat arrogant leader will certainly downplay and suppress serious issues to save face. And i'm afraid it's much easier with their independent, in-house approach, where most of process is under their control and NASA is just a passenger.So if any ugliness pokes out we better have to ships while one of them fixes their issues.
>>1803758While i find it cool that China put's effort into space this copy culture is disappointing. Means we won't see true generational leaps and competitive edge from them, just bigger numbers.
>>1808638It’d be easier and cheaper to solve humanitarian issues here, people aren’t going to stop having their problems if on another planet, it’ll just be orders of magnitude more difficult and expensive.Sure, our long term future may be in the stars, but we are always going to bring our issues with us anywhere we go. We’ll be hairy fiddling monkeys for a long long time still.
