Why didn't they insulate the Shuttle ET from the inside like the Saturn V. It would've avoided the foam shedding altogether.
>On January 19, 2006, New Horizons was launched from Cape Canaveral Space Force Station by an Atlas V rocket directly into an Earth-and-solar escape trajectory with a speed of about 16.26 km/s (10.10 mi/s; 58,500 km/h; 36,400 mph). It was the fastest (average speed with respect to Earth) man-made object ever launched from Earth. NH reached Jupiter in 1 year>New Horizons received a gravity assist from Jupiter, with its closest approach at 05:43:40 UTC on February 28, 2007What can a refilled expended Starship launching a probe do? 6 months potentially?
>>14104357Today I learn Saturn V was not all just RP1-LOX wow
>>14104357External foam insulation was probably lighter.
>>14104357>>14104373Space is hard
>>14104363Yeah, everyone forgets the metallic oxygen fueled fourth stage
>>14104360It can yeet itself there in a year, aerocapture, and spit out a bunch of smaller probes.

>>14104247From the moment I understood the weakness of my flesh, it disgusted me. I craved the strength and certainty of steel. I aspired to the purity of the Blessed Machine.Your kind cling to your flesh, as if it will not decay and fail you. One day, the crude biomass that you call a temple will wither, and you will beg my kind to save you. But I am already saved, for the Machine is immortal…...even in death, I serve the Omnissiah.
>>14104338>>14104332>this thing actually could work now that starship existsWell ill be
>>14104440What ifStay with meWhat if we removed the atmosphere?
>>14104440just use its gravity to slow down first
>It's been calculated that with a light payload and an elliptical departure orbit Starship could get to Mars in as little as 50 days. Or Titan in a bit under 2 years.There is absolutely no reason not to use Starship for Dragonfly holy shit
>>14104467The orange cylinders are suspected flight data recorders. SN20 isn't expected to make it down in one piece, so they want the data logs to be recoverable afterwards.
>>14104474Im talking about the circle and I'm pretty sure they'll test starlink on it

>>14104532But then the speculation isn't fun
>>14104541Your mom orbits my cock
>>14104573why would she orbit hen, that's stupid
>>14104578Because she's drawn to it as if by magic.
>>14104588I respect that she keeps a healthy protein-rich diet.
https://www.quora.com/How-fast-can-a-SpaceX-starship-travel-if-refueled-in-space>8.9 km/s is enough to go from LEO (Low Earth Orbit, already at about 8km/s) to the surface of the moon and back to Earth/LEO (with aerobraking at earth), or it’s just enough to get to the surface of Mars (with aerobraking) and back to low Mars orbit. Better to refuel Starship in a higher orbit such as GTO and gain another 2.5 km/s.brehs
>>14104638This is why EML2 will eventually be the high port for interplanetary traffic. You're damn near all the way out of Earth's gravity well, so even an ion drive can break orbit quickly.

Aerojet Rocketdyne's proposed NTR demonstration to be launched on a Vulcan.
Did 4ASS not already come to terms with bovine centrifuges? I thought we discussed this in detail previously.
>>14104332Threadly reminder that rocketry is quite literally archaic technology and we are destined to go extinct on this rock.
Threadly reminder to lick /sfg/s collective brown taint, doomer scum
>>14104680I considered that solution but discarded it because it didn't involve genetically engineered futa cowgirlsI mean you could put them in the centrifuge too, I guess

>>14104689>How will this help colonists eat?>"Eat?"
>>14104698futa cowgirls can also have other duties besides milking, you can't tell a regular cow to suit up and dust off the solar panels with a spacebroom
>>14104706>you can't tell a regular cow to suit up and dust off the solar panels with a spacebroomMaybe YOU can't
>>14104707Specialized cow EVA suits with remote control electroshock collars or however you intend to control your space cattle is extra mass. Futa cowgirls can use regular EVA suits.
>>14104713>he doesn't speak cowYou must learn the ways of the herd if you are to guide them, anon
>>14104715you can't have a corporate brothel with cows in it, you can absolutely have a corporate brothel with futa cowgirlsIt'll be a massive boost to the tourism economy of early Mars
>>14104694>12.5 thousand lbfso about 6 metric tons of thrust and you get about double the impulse per unit fuel-that's interesting.
>>14104713Virtual reality glasses. Make it think dust is grass. And some smell too maybe.
>>14104721Cowgirls? No, that is degenerate and disgusting.Mars will be home to catgirls, doggirls and wolfgirls, in order to cater to more refined tastes.

>>14104727you can't milk a cat, having multiple different breeds of genetically engineered waifus is a waste of precious mass and oxygen
>>14104740>you can't milk a cat,https://www.youtube.com/watch?v=bXNwzKo5Yps
>>14104740I don't want to milk a cat, I want to plow a catgirl. Big difference.
>>14104745well I want a big tiddy futa cowgirl to plow me so we're at an impasse
>>14104740>you can't milk a catAll mammals can be milked. Even rats
>>14104751Catgirl Mars will never cede territory to cattle-fuckers, I will never back down on this not ever
>>14104761is raising rats as cattle mass efficient? can we give them tiny little rat EVA suits, painted with holstein cow spots?
>>14104765Why would rats need EVA suits?
>>14104766>needIt's called the Bill of Rights not the Bill of Needs
>>14104766Just raise rats on orbit in a ratsat, they can feed tubefags who want to pretend they're still people
>>14104765i am actually kinda curious about trying to selectively breed rats to create milk optimally. imagine a new type of rat with big bulbous teats that lactates for its whole life, a creature that you could feed food detritus and waste and get healthy milk in return...anyone work in academia want to help me make this happen?
>>14104764Fine, but at least 1/4 of the catgirls need dicks
>>14104779They all need dick, just not attached to them
The stark difference between routine hops, and sudden stagnation for the orbital test. If the thing explodes before making orbit I'm just gonna check out of the minecraft server
What on earth is happening to /sfg/?Is it just one guy?
>>14104722so half the fuel flow rate of hydrolox for the same amount of thrust
>>14104777I was curious about this too and after some googling it seems like rats simply don't produce enough even in proportion to their body weight, you would need a lot of breeding before getting anything that can rival cow milk in terms of cost.
>>14104806who? the waifuretards? No it's nobody, just the voices in your head,time to take your meds grandpa its getting late.Anyways whats going on starship? any chance of an orbital test next month?
>>14104777I'm getting flashbacks to bug leg clusters the size of banana bunches and moon wizards
>>14104810true, but rats reproduce like crazy-up to 10 generations per year. but you'd have to figure out how to pick out the rats that had better lactation...you'd need to remove the babies and feed them offsite and hook the moms up to a rat milking machine that could measure milk flow and duration...yes...okay how do i get a grant application out of this I'm really invested now. and hey if it works we could have rat milk in space-we've taken rats to space already they're a lot easier to deal with than cows.

>>14104765No. Hyenas would actually be a very efficient milk-generating animal. Holstein cows can hold about 2% of their body weight in milk within their udders. Spotted hyenas can hold around 5% of their body weight in milk within their udders. A spotted hyena the size of a holstein would generate 26 tons of milk every year. They also have the highest protein content in their milk of any mammal.>>14104810See above. We already have access to the superior milking animal.

>>14104906>>14104843If they're gonna be so insistent on EUS they could at least make it refillable which the Hydrolox refill mission by Lockheed might show is possible, at least then EUS will have value and potential if NASA is gonna be forced by Congress to use SLS every year 1 launch
>>14104932It’s not that easy in hydrogen tanks
>>14104941Literally only because Shelby stopped ULA from working on it in 2009. They think they have the technology.
>>14104941Even NASA acknowledges it but we'll seehttps://www.nasa.gov/directorates/spacetech/solicitations/tipping_points/2020_selections/>Lockheed Martin of Littleton, Colorado, $89.7 million>In-space demonstration mission using liquid hydrogen – the most challenging of the cryogenic propellants – to test more than a dozen cryogenic fluid management technologies, positioning them for infusion into future space systems.

>>14104932>>14104944>EUS becomes refillable>NASA decides to launch it empty as a payload on F9 or empty but mated with a <=100t payload on Starship and use deployment/RCS to send it on a gentle intercept with a depot>now EUS can do SLS-Block-2 class missions to wherever the fuck it wants without waiting for a new orange rocket to creak its way down to the VABWatch Congress shit a brick again like when Jim proposed Falcon carrying Orion.
>>14104957>NASA decides to launch it empty as a payload on F9uhhh
>>14104943>>14104944I meant metal imbrittlement specifically. You could refill and reuse an EUS multiple times, but only so many times before the thing started to fall apart
>>14104963Not for re-use, just refilled in LEO ready to do SLS Block 2 cargo missions without waiting for Block 2 cargo to be developed as this anon shows >>14104957I see NASA taking this option if Lockheed proves out Hydrolox refill/storage for some weeks in LEO is doable
>boil offwhy not just put refrigerators in space...?
>>14104967Ah I see
>>14104963With the missions EUS retanked in LEO is capable of that's not an issue. They're all basically one way interplanetary missions or high energy/inclination military intercepts. If extended lifetime hydrogen embrittlement becomes a limitation it means we've got hydrolox depots orbiting either the moon or Mars or some fucking asteroid enabling round tripss.
watched apollo 13 the other day and played microsoft flight simulator off and on the last year or so.im really curious to learn the intricate mechanics of rocket/space shuttles and all that. i dont understand any of the shit they talked about in the movie like "stir the oxygen tanks"whenever i want to look up and learn that sort of stuff its just basic dumbed down stuff for normies. where can i autistically learn about the actual shit

The gap between starlink and the commercial and gov launches is hilarious, either starlink is commercial launches(since it is privately funded for corporate intrests) or it is government because the funding for DoD reasons. Either way it is a massive amount of launches that they are taking away from the graph to keep the Europeans from being angry about their lack of Aerospace spending. Its basically the same as the chinks that go on here and spout the "china is surpassing the US because spacex is a private company and doesn't count". Seriously its embarrassing, also funny how it doesn't include real 2021 values
>>14105219It's also mounted to a particularly massive swing-arm that has to get quite a ways out of the way when stages are being lifted, so that might be contributing to the impression of bulk.

>>14105408kek. Good edit.
>>14104650The first dairy animals on Mars (besides women) will definitely be goats and/or sheep. They have a much smaller footprint than cows, far less picky diet, more robust skeleton (so losing bone mass/muscle density from low gravity probably will be less debilitating). Goat and sheep milk can be drank or made into yogurt, ice cream, or cheese.The first dedicated meat animals will probably be fish. The first terrestrial meat will probably be rabbits for the same reasons that goats and sheep are preferred over cattle. Rabbits also procreate and grow very quickly. They géstate in about a month, have litters of up to a dozen, and grow to 5 lbs in 10 weeks so after a few cycles you’d have enough rabbits to sustain the colonies meat needs until it’s more advanced and has the resources to support more earth-like food production.

>>14105265> a lot of those Ariane "customers" are US government satellitesThat is absolute bullshit.

Unironically tinfoil is pretty great for space
>>14105909Cool, need a replacement for the BSC off Kenya. Speaking of, in Italy there's a scammy looking company that is publicizing a meme SSTO and vertically landing cubesat launcher with 10kg payload to SSO and somehow got 1.5 millions euros in grants. I guess everyone is trying to hop on the commercial launcher (with little to no substance) bubble.
>>14105667Now that I think about it, a lockheed lander would ALSO be hilarious because the crew compartment is just an Orion hull. So by scheduling it on a rocket such as a FH it just shows congress that orion can get to gateway without SLS hahah
>>14104843All I see is that they’re going to take four RL10’s and put them together and that becomes the exploration upper stage. It’s not that easy in rocketry

>>14106139The versions on the Exploration Upper Stage are a new variant of the RL-10C, which has an extended carbon nozzle, and a history of being a big fat pain in the dick.

>>14106287>In 1931 Herrick began corresponding with rocket scientist Robert H. Goddard. Goddard was a physicist whose ultimate goal was manned and unmanned space travel. Herrick asked if he should work in this new field which he named astrodynamics. Herrick said that Goddard had the vision to encourage him "to anticipate the basic problems of space navigation." As early as 1936, he had developed a plan for using mathematics and celestial mechanics to solve such problems. Two decades later America had the navigational methods needed to fly Earth satellites and to travel to the Moon and back.>In the late 1940s, Herrick began a one year course at UCLA on rocket navigation. In his mimeographed text book titled Rocket Navigation, copyright 1948-1951, he reworked the classical formulas of celestial mechanics to be more useful in the space age. In the early 1950s the enrollment in this course was around 6, but after Sputnik (1957), it was made a night class and the enrollment jumped to around 35, mostly local aeronautical engineers.

>>14104654Nu uh. They'll just cryogenically ferry the cow sperm and embryos to Mars, and then build a facility there to produce test tube cows. Create a dome for grass, and feed them that gas; then plug their buttholes to a methane tank and make starship fuel from their farts. It's a kg of mass to ferry enough cow sperm and embryos to make a thousand cows on Mars than it the kg cost mass to ferry one live cow to Mars via a rocketship.
>>14105167>>14105171>48days/AUThis dude's calculations means you can put 75T into Pluto's orbit in 5.13 years without a single gravity via a Tanker Slam. That's absolutely insane. I know he puts 150T for payload, but I've halved it as a principle that 75T of fuel mass will be lost to slow down to get said "probe" into Pluto's orbit.https://solarsystem.nasa.gov/missions/new-horizons/in-depth/>478kgLmao. You can put 68,038.9 tons of USEFUL PROBE PAYLOAD into Pluto's orbit with this instead of a flyby that NASA did with New Horizons, and it took 9 years to reach Pluto with gravity assists. You could put 142 New Horizon Probes into Pluto's orbit with a Tanker Slam maneuver.

>>14106422The crazy thing about it this is that a volcanic eruption has gigatons of energy releases. You can see the wavefront from the initial explosion travel right through the Coriolis flow of the circulation just North of it (south in the latter half) and despite the intensity of the wavefront, the sheer density of the energy of that developing storm system is so intense that its not even remotely influenced by its effects.
>>14106531Pluto/Charon ISRU hopper when?>The Triton Hopper concept proposes the use of a radioisotope rocket engine that would collect nitrogen ice on or below the surface, heat it under pressure and use it as propellant to explore Neptune's moon Triton. The largest technological challenge is to learn how to mine local surface nitrogen ice, and how to heat it for use as propellant. The rocket-powered hops are estimated to be up to 1 km high and 5 km long>A rocket-powered vehicle, or "hopper", has several advantages due to the variety of terrain and a gravity of only 8% of that of Earth. Hemispheric traverses and atmospheric sampling are possible during hops.https://en.wikipedia.org/wiki/Triton_Hopper
>>14105167Just for the record SpaceX got a lot of DoD money to look into a miniraptor for an F9 methalox upper stage. It obviously never became a reality, but I bet all the preliminary designs have been done by a team in Hawthorne and could be applied one day with "minimal" (relatively speaking) cost. In other words, even if it cost a few million to one day convert the inevitable Raptor 3 merlin-upgraded mega spacex engine into a miniraptor, NASA could easily supply that cost within their budget and give them a 2 year timeline from start till launch date and it could happen
Wait explain tanker slams to me, what exactly do you do and how does it work?
>>14106573Doesn't matter when a satellite is capable of 60Gbps second up or down. Plus, there's the idea of oversubscription, and in the event of a major planetary event like a seismic event or volcanic eruption, it would be trivial for SpaceX to deprioritize general traffic and prioritize high resolution image data from the extra sensor package to capture as much as possible both for science and for early warnings for tsunami, weather, etc.

>>14106601A raptor upper stage has way better dV potential than just about anything else on the market. Someone did the math on the spacexlounge subreddit, where they found out that a raptor upperstage for the FH could put 60T to LEO while being able to reuse all 3 launch cores. Fully expendable would be in excess of 60 tons, but would ultimately be limited by the diameter of the fairing. All that said, I suspect that Elon basically accepted the money to make the Raptor, but had an in person presentation with all the top brass and basically dissuaded them from the idea of an incremental rocketry advancement via a Raptor upperstage and convinced them to go all in on Starship. 150T to LEO without a single tanker launch is mind boggling potential even IF both booster AND Cargoship is lost after every flight and it costs say $500M to launch them. The only other equivalent comparison is SLS Block B, which is expected to cost between $2.25 and $2.5Bn to launch 150T to orbit. By simple linear comparison, the cost of Block B would afford you 4 Cargoship launches, giving you 600T to LEO expendable vs 150T expendable.USAF likely agreed to the notion and allowed the funding for Raptor to be leveraged for Raptor to Starship. Plus, consider 150T to LEO for Gen1 Starlink via an expendable Cargoship; means that 60 Starlinks weigh 17 tons and 150T into direct orbital injection = an approx 9x volume increase. 540 Satellites into orbit. ESSENTIALLY, IMAGINE LAUNCHING A COMPLETE SATELLITE MISSILE DEFENSE TRACKER NETWORK WITH A SINGLE CARGOSHIP LAUNCH INTO DIRECT TARGET ORBIT INJECTION.China and Russia would be unable to counter that. 540 satellites are 9x the F9 volume. Fun fact, that also means the Cargoship would be able to do 9 different orbital shells of 60 each via a single expendable launch. The coverage would be so significant, it would give USAF total orbital supremacy. It's nuts.
>>14106658>1 frame every 5-10 seconds>when the satellite is in a 350-500km shellNig is you serious?
>>14106604Basically it comes down to refuelling a starship on the most elliptical orbit possible to maximize delta-v while keeping the oberth effect. You can keep stacking tankers to make the final refuel apogee as arbitrarily high as you want.
>>14106661They took this from us.
>>14106659>total orbital supremacy
>>14106672Not really. The collapse of the USSR doomed the space race. Sure, US played a major role in accelerating it, but frankly, if we're being actually serious; the failure at Chernobyl was THE TITULAR EVENT that signed the death warrant of the USSR. They built RBKM reactors cause they were dirt cheap, but were incredibly unstable by the nature of their design. Couple that with corruption at every level of government and a paradigm where truth and scientific consensus when dealing with forces in the domain of "god" taking a backseat to political interests, and the nation was already dead; it just didn't know it yet. The consequence of that failure, is all aerospace ambitions were neutered once and forever; and with no real competitor to keep the US on its toes in space, it was no reason to extend beyond Earth orbit, and over time became a shell of its own ambition. China is now picking up the torch from Russia, with its own space program; but it'll be at least a decade, because the US takes China as seriously as it did with the USSR back in the day--and for China to take itself equivalently as serious with orbital and extra-orbital force projection.
>>14106670Do you refuel on each orbit or what? Like every time you swing back down to earth you meet with a tanker, fill up, and burn again?
>>14106661>>14106697Basically its Stalin and Lenin's fault, and Gorbachev's reforms came too late. He was the right leader for the nation to become less corrupt and more Republic-like, but was tragically born at the wrong time.
>>14106644I bet you that back then, instead of saying the thread is dead, the journalists were saying, "Spaceflight is dead," and "IT'S OVER" every time something failed.
>>14106707Gorbachev was an incompetent and basically had nothing to do with running the country at all
>>14106722>had nothing to do with running the country at allThat's my point though. By the time he came into power, there wasn't a country left to run. Everything was falling apart around him. He came into power in March of 1990 and the USSR collapsed in December of 1991. 1 year and 3 months isn't enough time to do anything and you basically look like a dumbass in charge of a sinking ship.
>>14106734he took over in 1985, please know what you're talking about before you start having opinions on it
Can I getta webm of the kino boostback?https://youtu.be/Wi9oddXzQG0
>>14106746>>14106748The coolest part of this launch is that we actually something interesting SpaceX is doing with its landing profile. Upon MECO and stage separation, they do a hard burn on the nitrogen thrusters to begin the rocket pivot significant enough that the flat side of the booster will face the exhaust from the second stage ignition. The resulting exhaust even in the ultra thin atmosphere, and the proximity of the two stages is sufficient, that the acts as an extra push. It's free dV to the main core, which helps it flip the entire way and the central engine then kicks on and does its boost back burn. That's the secret sauce of their landing methodology that I think was mostly missing from all the launch videos we've seen to date. We've got proper visual confirmation now. Absent of the second stage exhaust velocity impart, the turn around time with the cold gas spin, would mean that there wouldn't be enough fuel in the core stage by the time the landing burn kicks in.
lots of happenings with russia today. still on the lookout for other possible space attacks, but havent noticed any yet. i totally expect gps to get jammed across eastern europe (northern too?) as early as next week.
>>14106768would SS+SH use the same secret landing sauce?
>>14106789https://youtu.be/Wi9oddXzQG0?t=259Pay close attention to what the first stage is doing, at stage separation, and then acceleration of how quickly the booster pivots on its axis before SES and after SES. Remember that even as the booster is pivoting on its axis, the horizontal velocity until MERS is still making the central core go --> direction instead of <-- direction.>>14106809Yes, but, SH stages too low in orbit. So, SpaceX is pushing the innovation boundary here too. Instead of having explosive bolts that push the stages apart, as is happening MECO, they plan on gimbaling the central engine cluster to the left (relative to a 2D example in your mind, hard to make a Z axis approximation that high up in the atmosphere, sorry). Similar to how they're using the 2nd stage spin to yeet the Starlink satellites, they plan on doing similarly with SS. The residual velocity coupled with the gimbal action, will cause SH to go <-- way without needing hot gas thruster ignition (though that will come later for the pivot). This has two benefits:1. It'll get the SH movement started for the boost back/landing sequence. SH is much bigger and heavier than the F9 core, so this is necessary.2. That action will transfer angular momentum to SS. It will cause the stage separation and distance between SH and SS. It will additionally open up the broadside of SH to the 6 vacuum raptors that will be on SS. Upon ignition, the initial exhaust thrust will accelerate the booster pivot and that imparted velocity will decrease over time as the SS pulls away.The rest of the landing profile is a copy of F9, because SH is just a WAY BIGGER F9. The math will end up being mostly the same but scaled for the mass diff.
What's your favorite constellation, anons?Mine is Orion, easiest to spot for me and first one I've learned. Contains its famous belt and popular stars like Betelgeuse or Rigel. And on top of that you can see it in good detail even with high levels of light pollution.
>>14106830>because SH is just a WAY BIGGER F9>F9 landing on the landing pad and drone ship in very small area time and time again>booster catch might actually fucking workholy fuck
>>14105078>DoubtYou're forgetting the huge mass difference between Centaur and F9 stage 2. Yes, Centaur pushes more payload for its mass, but the F9 stage 2 masses so much more that the net payload is higher. The same reason explains why the Falcon Heavy hugely out performs the Delta IV Heavy despite both having roughly the same liftoff TWR and the Delta IV Heavy being way more efficient on every stage. Hydrolox just doesn't have a lot of mass, so even if it gets a 20% better payload mass ratio in terms of actual net payload it sucks dick.

In terms of KerlOx gas fed turbine engines go, Merlin-1D++ is basically the pinnacle of performance. Over the life of the engine's iterative improvement regime, thrust to weight ration increased by 265%. That's INSANE. Yes, the Centaur upperstage courtesy of its hydromemes propellant can burn for a 135 seconds longer, but 450.5s * 22,300lbf = 10,046,150lbf of total exhaust potential vs 69,146,000lbf of total exhaust potential.The Falcon 9 second stage can do nearly 7x more in 30% less time with the same amount of mass.

>>14106929That's only cause the Mun is like 1/2 the size of the Moon, so the hydrolox kN output is good enough to land something as heavy as orion on its surface easily. If the Mun was any bigger, you wouldn't have enough thrust output from the 2 engines of the centaur upper stage to make it to the orbit without failure. Kek

>>14106957No, it is, but only in KSP and only for the Mun. It's not possible for the actual Moon. Orion is a yo momma's so fat, she needs an exploration upper stage to make it to the Moon.

>>14106995>I sure do like clueless 15 year old boys posting hereIs it making you hard, anon?
>>14106964>>14106957In KSP, take the Centaur III upperstage and increase the number of engines from 2 to 4. Put Orion on top of it, get it to the Karman line like Below Orbit does, and then try to land back on Kerbin propulsively using the 4-engine Centaur III upperstage with landing legs while carrying big bertha Orion. You'll find quickly, that even with 4 engines, the kN output relative to the fuel/mass ratio of the entire vehicle is so utterly shit, you'll pancake into the ground rather than actually land.The Delta IV heavy has 3 RS-68s, each of them have a 3,137kN. So to get 31 tons (D4HV) to LEO, you need 9,375kN of thrust. Orion BY ITSELF weighs 22.7 metric tons. 73% of the D4HV payload to LEO capability is taken up by Orion. Doing linear approximation you need 6,864kN of thrust to get Orion to orbit OR to land Orion from orbit propulsively back onto Kerbin. But if you're landing, you want like 5% margin on fuel in case something goes wrong, so the actual kN value is greater closer to 7,332kN (I know fuel/mass/exhaust velocity doesn't work like this, but we're doing this relative to KSP, so deal with it).The 2-engine Centaur III upperstage is powered by a pair of https://en.wikipedia.org/wiki/RL10 engines. Each of them have a thrust profile of 110kN. You put four of them together on the same tank, and assuming plumbing and flow works for magically, you'd get a combined thrust profile of 440kN. You need 16x MORE thrust to handle Orion in a gravity well during landing on Earth. Kerbin is like ~40% the size of Earth and Mun is 1/2 that. Assuming napkin approximations (and at this point this math is super sketch, but for the purpose of this example, its probably good enough), 40% of Earth @ 7332kN = 2,932.9kN. Mun is half that, so 1,466kN.Kerbin landing thrust requirement with Orion = 2,932.9kN approximateMun landing requirement with Orion = 1,466kN approximate4-engine Centaur III stage w/ landing legs w/ Orion = 440kN actual. Fucking lol dude.
>>14106979Wouldn't the relative positions of the stars shift slightly during the 20,000 years between these cave paintings and today? Probably not by much, but at least a little. I'm sure there's a way to see what the constellations would've looked like at differing points in the past.

From Earth's frame of reference the seventh sister hasn't been visible in about 100,000 years, and so the developments of language and oral history must stretch back to before the emergence of anatomically modern humans. It's a complete disproof of creationism and Imago Dei because it shows consciousness predates the modern human form.That cave painting is totally a star map.https://theconversation.com/the-worlds-oldest-story-astronomers-say-global-myths-about-seven-sisters-stars-may-reach-back-100-000-years-151568

>>14106938Mun has a gravity of 1.63 m/s^2, the Moon has a gravity of 1.627 m/s^2, also Ksp doesn't have hydrolox and kerolox, it has one bipropellant type. The Moon is about 8.7 times wider than Mun, but that's true of every object in Ksp since the entire system is shrunk down for game balancing purposes. Also the original picture in >>14106278 is of the EUS which has 4 RL-10 engines. Finally the fact that you took a comment about ksp that seriously makes you kinda retarded
>>14107099Where do you think you are.

>>14106798I hope US GPS assets are severely affected. maybe then congress will take space force seriously and we can balloon the budget and launch more stuff
>>14107145thats it, i hate this fag now
>>14107140Caturday or not this is still a blue board.
>>14107011>>14107037You fucking retard, you're comparing size, not gravity. The Moon and Mun from Ksp both have about the same gravity, which is one 6th that of Earth gravity. You're also comparing liftoff thrust to low Earth orbit capacity which is incorrect and dumb. You're ALSO conflating thrust to delta V, which is beyond stupid.For liftoff, the only thing that matters is having more thrust force than weight force, which depends on local gravity, which again is 1/6th of Earth gravity. 440 kN lets you lift anything that masses less than 44.86 tons in Earth gravity, which means in lunar gravity your vehicle can lift off as long as it masses less than 269 tons. For landing on the Moon and returning to low lunar orbit you need a total delta V of about 4000 m/s. Even if I take pessimistic numbers for dry mass (26 tons for Orion plus the service module and another 28 tons for the dry stage with legs), the known propellant mass of 129 tons on the EUS with the 460 Isp of the RL-10C3 gives a delta V of 5,554 m/s, which is more than 1.5 km/s more than is necessary to do a Moon landing and return to orbit single stage. Also, in reference to the Moon, the vehicle would START with a thrust to weight ratio of over 1.45 at full throttle, and would only gain TWR from there. So basically, your numbers are bullshit, you are LARPing as someone who knows anything about rocket vehicle design, and you should shut the fuck up and read some books.
>>14107155>Elon was uncomfortablelol I'm sure he cringed so badly he just closed the browser
>>14106278So would it work or not, fuck KSP numbers I want to know IRL
>>14107165Dark streaks trailing beads of liquid doesn't make any sense unless that's liquid shoe polish
>>14107167How have you figured this out but NASA haven't that a fucking Orion + EUS can serve as the lander holy fuck... If we're stuck with SLS and EUS then they can at least do something interesting with it, but ICPS is totally shit.Crazy to think NASA could have had their own lander if they just did EUS integrated with Orion, but then no Starship HLS...
>>14107186>>14107167Can Starship or another vehicle launch just an EUS+Orion lander? I feel like EUS and Orion are worth salvaging even if they scrap SLS
>>14107175see >>14107167short answer yes, but you need to figure out hydrolox lunar orbit propellant transfer to make it actually practical
>>14107167>on the EUS with the 460 Isp of the RL-10C3 gives a delta V of 5,554 m/sfuck me, hydrolox is King in the vacuum
>>14107186>>14107193The reason Orion+EUS lander is never going to happen is because it would cost a gorillion dollars and take 1500 years for boing and lockmart to develop and deliver. On paper, the concept is sound, but in real life a much safer and more practical bet would be to buy a bunch of methalox GG engines Rocketlab is going to make and commission a life support pallet module that can be loaded inside a big steel tank to make the lander's habitat section. Have two engines for redundancy but only use one at a time, rely on propellant shipments via Starship, simple as.
>>14107060do retards actually think consciousness just switched on randomly one day?
>>14107171Elon's a total chad. Every single kid's he fathered has been a boy. He's been married thrice. Its kinda ridiculous. Yeah, he's got Aspergers, but that doesn't detract from the fact that he's everything that Erryday Soi Boi isn't. That part II tweet the baldie makes is like when a drug dealer gets high off his own supply. The dude let fame get to his head and thought that because Elon likes making jokes about bouncy trampolines and occasionally references Rick and Morty for some of its comedy, that means that an idea discussion somehow means a blank check to keep going when you shouldn't. So yeah, I bet that Elon def closed the browser/app/w-e and ignored him until he asked an appropriate question. In part one, he talked numbers. Yeah the whole catching it with a net is may may fanny, but its still MATH based. Part two is soi boi failing to read the room.
>>14107207A methalox stage of the same mass would have far smaller tanks and the resulting increase in wet dry mass ratio gives the equivalent vehicle a delta V budget of 6204 m/s of delta V. A ~650 m/s improvement plus all the benefits of a more easily stored fuel with higher TWR engines and no embrittlement issues. Hydrolox is ALWAYS and FOREVER a SHIT, no exceptions.
>>14107228Maybe Elon is like that because he actually has two Y chromosomes and no X chromosomes per cell
>>14107230aww shit, I fell for the ISP numbers
>>14107236many such cases
>>14107240wonder why NASA didn't take the Methane pill
>>14107193To be fair the lockmart proposal literally uses the orion hull as the crew compartment, and the 4X RL-10 lander is essentially running on an EUS for all intents and purposes

>>14107252That graphic makes me want to puke, what the fuck is that a highschool project?
>>14107253Problem is with dust on the suit. If you bring that inside you're pretty fucked. Inhaling lunar regolith is like inhaling a million razors. Your alveoli are gonna get lacerated and you'll wish you weren't born.
>>14107259Are you disabled?
>>14107262I come here, so yes.
>>14107259The solution is to hose down the airlock with water every time you come in from an EVA, which knocks the dust down from mild hazard to zero hazard. Lunar dust is FUD material like none other, only cosmic rays get more unwarranted attention.
>>14107167this is why one should play with real solar system and all the realism mods to avoid being called a retard
>>14107259Yeah those 99 year old apollo astronauts are going to die of shredded lungs any day now. Certainly won’t be old age that gets them
>>14107259Put a shower in the airlock, drain on the floor with a filter you periodically have to empty.
>>14107259Are you European?
Retards in this general have never heard or a suit port
>>14107274I'm Canadian. Sorry.
>>14107265>>14107269yeah lets use the most precious lunar material to wash pressure suits lmao
>>14107276Ruins suit aesthetics, unnecessary with a dedicated airlock and EVA stowage deck aboard Starship HLS
>>14107280>land a Starship on the Moon with 100 tons of water as payloadSpace is too hard, guys
>>14107282>suit aesthetics>aestheticsthis is why you'll never be a competent engineer
>>14107254You need full flow staged combustion engines to make the methalox math work. NASA has tried running the RL10, an expander cycle engine, on methalox and IIRC they still didn't get the magic 380s Isp needed to beat hydrolox in total delta-V. FFSC engines are much larger and heavier, and so NASA hasn't had a rocket that could benefit since the Saturn V. For ICPS/EUS in particular the goal was zero new engine development beyond tweaking the RL10 a bit.Also for deep space paper rockets LH2 has been preferred for decades because water ice is a lot more common than carbon in the outer system. We didn't even know our own moon had surface carbon until less than a decade ago. Availability is king for ISRU.
>>14107280>>14107280>implying 90% of all lunar water wont just be imported from earth on the cheap by starships anyway.If you actually think the "muh water on the moon" was a good justification to go, unironically kill yourself. it's bullshit to placate retards like you

>>14107276>>14107289He's right, it's why xEMU looks like Quasimodo. The real redpill is that suitports only make sense for powered hardsuit mecha that can be kept at 1atm cockpit pressure.
>>14107301Water is stored in the balls
>>14107301balls to the wall curazzy
>>14107280Honest question, do you come from a southeast asian country? Do you not understand what water treatment is? You have an airlock dust decontamination system based on water spray. It's charged with 100 liters. During a decontamination cycle the water is sprayed, it falls to the floor, it enters a sump, it's pumped into a tank, and it gets pumped from the tank back to the nozzles. The water circulates for as long as you run the decontamination sequence. When not decontaminating suits and equipment (ie 99.99% of the time) the water in the tank is agitated and run through a particulate filter column. This filter column actually just a large fabric bag packed with crushed lunar rock (crushed rock doesn't have the same attributes as lunar dust, because the crushing action destroys the 'sharp' features produced by vacuum deposition of vaporized SiO2). The slurry water is pumped up onto the top of the filter pack, and it percholates down until it flows out the bottom, having had all dust grains removed. This self-cleaning cycle operates continuously until either the next return from EVA, or until the water of the system reaches an acceptable level of clarity, at which it is determined to be clean and the system goes into standby mode.So in short, you bring 100 kg of water to the Moon on top of the multiple tons that you're bringing to handle every other human-life-support related task that water performs on a Moon base, and you use that water perpetually to prevent dust ingress. Over time the water does evaporate a little and needs to be replenished, but all of the water that evaporates is pulled back out of the base's air in the dehumidifying system anyway, so the net loss of water is zero.
>>14107311It's not that easy in recycley
Would pykrete work as a hydrolox depot material? Water ice and wood fiber are already extremely hydrogen rich so embrittlement is a non factor, and a depot doesn't need to be super light if you can just make station keeping thrusters bigger.
>>14107295>You need full flow staged combustion engines to make the methalox math work.No you don't. Even at 350 Isp the methalox version I described gets a delta V of 5714, which is still better than the hydrolox EUS. 380 Isp is not a 'magic number', the advantage of methalox is more in the density of the bipropellant combined with the storability and flexibility of engine cycle choice. You're also wrong about FFSC engines in general. Their biggest advantage is the huge chamber pressures they can achieve, which leads to very high TWR, which means they're actually the lightest option for a given thrust output (ie, an expander cycle that made 500 kN would mass a lot more than a FFSC engine that made 500 kN). For ICPS/EUS in particular the goal was to maximize money being siphoned into the respective hardware provider companies by offering the least capability and technological improvement for the greatest cost.

>>14107327Being hydrogen rich doesn't matter for hydrogen embrittlement, having a metal that readily forms metal hydride compounds being exposed to hydrogen is what causes hydrogen embrittlement. Carbon fiber composites are totally immune to hydrogen embrittlement, for example. Here's the thing. Metals in groups 7, 8, and 9 on the periodic table do not form metal hydrides readily or at all. The most obvious one of these metals to use in a hydrogen tank to ensure zero embrittlement is the very exotic metal IRON. That's right, your typical chunk of iron is immune to hydrogen embrittlement. Now, if you add a bunch of additional metals to form a fancy alloy, you may end up creating a mixture that does actually get embrittled by hydrogen, but if you aren't RETARDED you can just make your big hydrogen storage tank out of relatively pure iron (or iron with some cobalt and/or manganese).
are we about to enter the age of the aerospike?
>>14107336Wouldn't want to rock the boat and mess up that carefully tuned military industrial complex now

>>14107392There are laws against that sort of naked graft which is why we're in the situation we're in now. A better fix is requiring bill sponsors to read the full text of their bills aloud before they can be voted on, which would stop the 5000 page porkzillas from existing.
>>14107369Context is a guy talking about building a stationary orbiting fuel depot out of thick walls of frozen wood pulp and water. Mass not an issue. Also, Starship and the original Atlas rockets both prove iron structures can still get excellent mass ratios.
>>14107414They would still be as long as they are, if not longer to make sure everyone is bored out of their minds. Reading them would just be a custom and slow everything down even more
>>14107421Formality I meant, not custom, and also if you introduced a law where you at least had to read aloud a summary of each bill it wouldn't change anything. Even if you snuck shit into your bill that hindered NASA or demanded 2 landers and demanded more SLS launches or whatever, politicians don't give a SHIT. They only care if it increases or decreases jobs in their district and helps them get reelected
>>14107362If you want aerospikes to be useful then just build a Venus colony
>>14107421Requiring a full reread after every amendment would stop the frivolous pork packing process that happens now dead in its tracks.
>>14107435Even if a Venus colony made any sense, it would unironically be better to build a big ducted fan powered "first stage" launch platform that would use the high density atmosphere to ascent to an altitude of >50 km then from there your typical bell nozzle two stage rocket gets to orbit in an earth-analogous manner. Meanwhile on Titan you would either use the same ducted fan thing OR you could use air-ingesting turbofan engines that use internal fuel-oxidizer supplies to get up to >1500 m/s which is a suborbital trajectory in that low gravity, then circularize using vacuum optimized bell nozzles on a rocket engine. Once again better options available than the heavier, overheat-prone aerospike rocket nozzle.Aerospike lovers forever cucked lmao
>>14107406nah, its short lived & localised
>>14107451So you're saying we should devote a few hundred million towards setting up a permanent artificial meteorite display over every group based telescope observatory on the planet? I agree
>>14107464Too expensive, we already have the final solution to the astroonomer question
OK, since the one semi reasonable argument in favor of hydrolox was ISRU, let's look at all the places that have a mix of carbon, oxygen, and hydrogen available for methalox ISRU.>Mars (duh)>Ceres (visible water ice and a shitload of surface carbon)>Callisto (CO2 at surface level, liquid subsurface water)>Titan (duh)So the one place people can reasonably do round trips to with chemical rockets that doesn't have easy methalox ISRU is Venus... but Venus is cheap and easy compared to the outer system. Refuel at EML2 instead of in LEO and you can easily carry enough propellant to insert into Venus orbit, do your mission, and come back to EML2.Methalox hot gas RCS would therefore make sense even with fusion rockets since it's a hell of a lot easier than synthesizing NTO/UDMH in situ.
>>14107483>Refuel at EML2 instead of in LEO and you can easily carry enough propellant to insert into Venus orbit, do your mission, and come back to EML2.Venus atmospheric sample return...

>>14107805yeah, I saw the comment above mine after having posted.anyways, some guy named Faka’iloatonga Taumoefolau (Project Coordinator for the Tonga Parliament Buildings Project) has a couple of images and another video in the comment section. Seems legit this time.
>>14107803There's video of the remnants of the tsunami splashing into San Francisco Bay about six hours ago so I suspect the US will investigate.
>>14107792im still waiting for the mythical tirada to make an appearance. it's going to be wild if it does.>In late 2017, a Russian military official appearing before a parliamentary defense committee described it as a “mobile complex for the radio-electronic destruction of communications satellites.”>In early 2018, an anonymous source within Russia’s military industrial complex told the Interfax news agency that Tirada-2 was capable of “disabling communications satellites”
>>14107794It doesn't have to be violent, it's a flat island at sea level with no high buildings, all it takes is for the sea level to rise significantly for a few minutes and most people drown
Bros I started reading Ignition! but I feel like I'm being filtered by all the technical chemistry shit. Is it worth it to continue or should I give up and read a different book?
>>14107764Won't Yellowstone vaporize all of the pacific and rocky regions, blanket all of North America in volcanic ash, and kill effectively everyone in the entire northern hemisphere if it erupts?
>>14107783what the fuck
>>14107820I haven't taken chemistry since high school and I was able to follow along.

Sea communication cables are damaged as a result of the volcanic eruption. Further and better updates will be available as the day unfolds. Source: DFAT Helpline.doomerposters, we got too cocky?
>>14107853>no casualtiesObvious bullshit. Even for tiny stuff there's still casualties.
>>14107843any ubdates from Samoa
>>14107853>no casualtiesGood. For a moment there I was going schizo because I thought the whole island got wiped and noone reported it.

>>14106835I'm a pleb with glasses that's lived in built up areas for most of my life so Orion is one of the few I can see with my own eyes. It was also the first one I did space research on back in elementary school which left a lingering fondness for the hunter.
I want to know if there are any updates on the oil platform and if they are planning on catching the booster on the oil platform or landing on it.

>>14107581what about those circular detonation engines?
History will remember BO as the pioneer of propulsive landing and reusable rockets and no amount of lying muskrats will change this.
>>14107966>quite pungent indeed
>>14107966I wonder what the biggest explosions on Io look like
>>14107930Totally different technology and also the high reported Isp was because they were using hydrogen and air, for reference a typical jet engine converted to burn hydrogen and air will get an Isp of like 20,000. In reality the specific impulse of RDEs won't be remarkably higher than that of normal rocket engines, however an "ideal" RDE design could be lighter overall and wouldn't need to have super high pressure turbopumps because the chamber would operate at a low static pressure and RDEs don't need nozzles to accelerate the propellant to high velocity in theory.

>>14108005>RDE design could be lighter overall and wouldn't need to have super high pressure turbopumps because the chamber would operate at a low static pressureseems like a superior engine in every aspect. So why aren't they used, what are the practical realities of RDE?
>>14108012This is probably why Zubrin is so hellbent on going to war. The only way humanity will reach Mars quickly is if Earth is fucked.>>14108042How do the French get away with naming their rockets after girl names>Maia>Ariane>Adeline

>>14108166why did spacex stretch falcon and starship?
>>14108184They uprated the Merlins so the engines could lift moar rogget.
>>14108187so you're tellin me they already uprated raptor

>>14108200because it's fake
>>14107054>>14106979Go look up the actual painting. The Orion section is very questionable ('ah yes, the vaunted 4 stars of Orion's Belt') but the position of the supposed Pleiades in relation to the bull (Taurus) is quite interesting.
>>14108205someone looking for a pattern will inevitably find one
>>14108190Step right up and behold: Raptor 2! we have all the engines in production, we've test fired them on the stands at mcgregor! you want proof? how about my infallable word, good as gold (or stainless steel!) And mind the rust!

>>14108235felon already stretched it, if you actually believe him
>>14108056Orange rocket good?
>>14108235No chance, wind shear
>>14107236Every time you see someone mention "Isp", replace it with MPG. Because that's basically all it is, it's how fast it uses fuel, not how much power it can give while driving/throosting uphill.High ISP is like a euro shitbox yugo that gets 50mpg but can't even get up 60mph on the highway.
https://youtu.be/7JwuW0Nq5-MI'll be there, anon, will you?
SLS stan twitter is something else man

>>14108205What I posted is the real paining, your image is shopped. All those spots are not there.>>14108232Not really, the nebula isn't in the same line. It's perpendicular, as part of the sword.
>>14108313>What I posted is the real paining, your image is shopped. All those spots are not there.My image isn't shopped you retard, it's an entirely different section of Lascaux.
>>14108313Here, some germ professor did his doctoral disseration on it back in 2004, I'm pretty sure he was the first person to bring the idea into the mainstream: https://www.researchgate.net/publication/289211311_A_Palaeolithic_Planetarium_Underground_-_The_Cave_of_Lascaux_Part_1Rappenglück M, 2004, "A Palaeolithic Planetarium Underground - The Cave of Lascaux (Part 1)"
>>14108331Also please note that by posting his dissertation I'm not agreeing with his ideas (I think they're interesting but a bit of a stretch). Merely posting them to show you're a retard who keeps claiming the images are shopped despite there being plenty of independent evidence out there to show otherwise (that, and using the eyes God gave you would also make you realise the bulls are totally different).
>>14108329Who are you my mom? also hoes mad
>le virgin overpayeed engineer working on SLS vs>Le chad mexican Juan working on water tank
>>14108052>>14108005 is right. The primary advantage of RDEs comes from their relative mechanical simplicity and lower operating pressures. RDEs are a VERY long way from leaving the lab, much less being used operationally. There was even a paper published recently that called into question whether or not there was even any pressure gain (the primary value of using a detonation wave to do your combustion) occurring in most laboratory RDEs. The Japanese test article that flew on a sounding rocket recently was closer to a gas heater than a working engine. I'm honestly somewhat skeptical if the theoretical advantages will ever pan out in practice, but thanks to their meme status, at least it's easy to get funding for them right now.t. works on an RDE research project
>>14108331Thanks for the link. Maybe, but the Orion bit is still wrong. Even with Gaia proper motions there's no 4th star back then.
Anyone have that pic of the giant room full of long tables with guys working on blueprints for the Saturn V with just paper and pencil?
>>14107820I understood it but it was so much methyl shit I forgot 90% of what the book was talking about
>A black hole in the Orion Nebula?>The Orion Nebula Cluster has long been known as peculiar. Its stars move at a rapid speed, as if the whole cluster were flying apart. If the cluster contained more high-mass stars, the speed of these stars would be easier to understand. But it doesn’t, and so astronomers have wondered why these stars move so rapidly.>An international team of astrophysicists – led by Dr. Ladislav Subr of Charles University in Prague – set up a computer model of the Orion Nebula Cluster. The model required a new method of dealing with the gas in this region of space and the way it is driven out from the young star cluster by the intensely radiating high-mass stars of the Trapezium. The model showed that, as the gas was being driven outwards, the cluster began to expand. That explained why most stars in the Orion Nebula Cluster move so rapidly. Many of the heavy stars were sling-shot out of the cluster, while some were driven into the center of the cluster and collided with the most massive star there. At some point, this massive star became unstable and imploded into a black hole, with a mass about 200 times larger than the sun.https://earthsky.org/space/a-black-hole-in-the-orion-nebula/https://arxiv.org/abs/1209.2114
>>14108388Interesting. On the same vein, what ever happened to the Event Horizon Telescope? Weren't they imagine SA* right before the pandemic hit? Did they just give up on trying to process the data?
SLS could actually be incredibly based with two simple and cost effective changes>replace the SRBs with Raptor powered RTLS advanced boosters>allow the core to refuel in LEO

>>14108505I agree. The resources would be better spent building autonomous hunter killer drones to deal with people like this crab bucket poster and the social parasites he claims to advocate for
>>14108552No, they do. But that's just coincidence and is unrelated to the similar-sounding name.
>>14108047Unironically a good song
>>14108474How many hundreds of millions do you think they spent on designing and building those extendable platforms to perfectly follow every curve of the orange rocket
>>14108552Well, they did.
>>14108525Nta but as a geologist I couldn't give less of a shit about cultures and civilizations that are destroyed by nature. If it happened in the middle of nowhere with zero casualties it would still be cool. Any deaths brought about by these events are just bonuses because liberals start freaking out, and more often than not find a way to do mental gymnastics to link it to climate change, and demand more funding that goes to geoscience research lol
>>14108478>SLS >simple and cost effectiveunironically impossible, it is designed to be as complex and expensive as can be justified by crying about space being hard.
>>14108542(She worked on SRBs at Thiokol)
>>14108562I was just thinking that. They are custom fit for SLS and have probably been in development since at least 2011 and only recently got installed a few years ago after multi-millions of dollars and hundreds of jobs lolMeanwhile spacex erects a tower using mexican labor in a matter of weeks. Also reminder that the SLS service tower was built from scratch and cost $2 billion
You have been visited by the hunga tonga-hunga ha'apai volcano of shockwaves and uncertain death. 20 to 30 cm tsunamis will come to you unless you post "goodbye ocean man" in this thread

>>14108539The engine is already assembled and being tested apparently, and the rocket is small with only 500kg to 1t payload capacity, so it's possible.
