First in for homemade lithium/fluorine rockets
>>11763201That's a pretty big crane.
>>11763201Holy shit look at all the starships.
Remember, no baiting.
Be sure to wish her a happy 10th anniversary everyone!
>>11763210
>>11763201Anyone know that the mystery dome is?>https://youtu.be/B60oNzlS_ro>https://youtu.be/PFbhDfKsYeI
>>11763214Happy 10th Birthday Falcon 9-chan!
>>11763201Remember to exercise! No fatties and skinny-fats in space
>>11763214He just said no baiting...
>>11763204>The impracticality of this chemistry highlights why exotic propellants are not actually used: to make all three components liquids, the hydrogen must be kept below –252 °C (just 21 K) and the lithium must be kept above 180 °C (453 K). Lithium and fluorine are both extremely corrosive, lithium ignites on contact with air, fluorine ignites on contact with most fuels, including hydrogen. Fluorine and the hydrogen fluoride (HF) in the exhaust are very toxic, which makes working around the launch pad difficult, damages the environment, and makes getting a launch license that much more difficult. Both lithium and fluorine are expensive compared to most rocket propellants. This combination has therefore never flown.lol
>>11763222And no transfats. Everyone start running
>>11763231How easy would it be to bike on Mars? With a non-bulky suit I imagine you could get some nice air off sand dunes there, given the reduced gravity.Also, if Musk ever uses Boring company to dig out big tunnels connecting habitats, a bike would be a cheap low-effort transport in there.
>>11763233Stationary exercise bikes aren’t that heavy. I’d expect a ton of similar equipment to be brought over for exercise
>>11763233>non-bulky suitgonna be hardThen again, 0.4G helps a lot
>>11763233I would not be surprised if an EV or methalox dirt bike/ATV gets made for Mars. In fact, Tesla is working on a companion ATV for their Cybertruck as an add-on.
Every daydream about spacecraft when you should be doing something else productive? Post your ideas. Bonus points if they're reasonably attainable with today's or near future technology.>"Venusian Lighthouse" - small unmanned space station/satellite in a high orbit around Venus (comparable altitude to geostationary height in Earth orbit>while Venus itself is rarely considered as a target for exploration due to its extremely inhospitable climate the planet is frequently used by probe craft for gravity assist maneuvers, mainly en route to the outer solar system (Earth is occasionally used instead when Venus's orbit brings it too far away to reach) >the purpose of the Venusian Lighthouse is to streamline exploration of the outer solar system that currently remains very expensive even with the upcoming reusable launch systems>a probe approaching Venus for a gravity assist would communicate with the lighthouse which would diagnose its systems for any problems, and give it maneuvering instructions to reach its final target without depending on Earth to do so with the light-lag>TL;DR a "Lighthouse" satellite orbiting Venus would make exploring the outer solar system easier for any probe using Venus for gravity assist maneuvers
>>11763236I don't want to be stationary, I want to tear ass down Olympus Mons. Stationary ones are a good idea for bringing on the trip though.>>11763237Wasn't some company working on some skintight pressure suit a few years back? Or did that just never work out? The prototypes just looked like a catsuit made of kevlar or something.>>11763243>Tesla is working on a companion ATV for their Cybertruck as an add-on.Neat, definitely happening then.
>>11763249Real shame Venus doesn’t have a Gilly
>>11763237I imagine in the future the boring company could dig a tunnel and it could be partially pressurized. You could don a skin-tight pressure suit with a helmet and get some sick air. It would be easier for someone born on Earth though, if you were born on mars it would feel like “normal” gravity so they would probably need to practice coordination a lot more I assume
>>11763201>>11763201Looks really promising, will SN5 be on the platform by tomorrow?
>>11763268Goddamn that didn't take long, I love this turnaround time for their prototypes, makes the failures far less consequential as each fixes the problem of the previous iteration.

>>11763218>The Mystery Dome has "4mm" and "304L" written on it. Could be for testing a new steel alloy, 304L-series stainless (The "L" signifies low carbon amounts, to lower the amount of carbide buildup while welding).
>>11763249Martian Mass Driver>~300km long up the western slope of Olympus Mons>can accelerate a 50t payload of cargo or passengers to Martian escape velocity at 4G>takes 10GW of nuclear reactors or solar to power>does NOT require superconductorsThe key partner technology for this would be the Plasma Magnet Drive - a smallish cylinder made of two pairs of saddle coils that let you interact with the solar sail (when rotating) or aerocapture (when fixed) by running current through it - a magsail without the kilometers of superconducting wire. It gives you enough anti-sunward delta-V to reach the gas giants, so you just need enough regular propellant to slow down, orbit a moon or asteroid, and then escape back to Mars. Conversely, it lets you get all the way back to Earth via aerocapture and reentry with no other propellant but some RCS thrusters.https://www.centauri-dreams.org/2017/12/29/the-plasma-magnet-drive-a-simple-cheap-drive-for-the-solar-system-and-beyond/The end result of this system is the ability to fling Cygnus style tin cans everywhere from Earth to Neptune limited only by Hohmann transfer windows, or to trade escape velocity for more mass and build monster ships in Low Mars Orbit for a pittance of launch costs. If you build particle beam "lighthouses" in orbit around the gas giants (possibly at their Solar L1s for ease of navigation) you can use the plasma magnets to brake, and then you only need enough propellant for breaking orbit to Trans-Mars Injection for the way home.In short, the Mars Mass Driver is the key to the entire solar system if it gets built before torch drives become available to put on private sector starships.
>>11763284The problem is >>11762280 they’ve just been sitting on their asses. Bezos doesn’t seem too concerned with testing like an insomniac and going after NASA contracts like a mad dog. Blue Origin has the money to succeed, but ultimately I think it comes down to a shitty company philosophy

>>11763286You should have just posted it here
>>11763311Okay but hear me out: just make a big rocket kek.A dedicated Martian launch stage would be so cheap that the difference to a mass driver per kg is quibbling over pennies, while being much cheaper to develop as it's just a rededication of existing tech.

>>11763355Based and economics pilled. The only place it makes sense to build an electromagnetic accelerator launch system is on the Moon, because on the Moon you can build it at ground level and have it encircle the entire globe. This is important because it means you can pick any comfortable level of acceleration that you wish, and just stay clamped to the track for as long as it takes to reach your target escape velocity, which can also be enormously larger than what you can achieve using a shorter mass driver. Hop onto a spacecraft the size of an ocean liner sitting on the Moon rail, accelerate at 1G net for ten hours and release, whizzing off at a comfy 294 kilometers per second towards the outer solar system. Slowing down left as an exercise for the reader.
one day i'll go to america to see this in person: https://www.youtube.com/watch?v=VBlIvghQTlIso beautiful
>>11763435https://www.youtube.com/watch?v=VUFwR364Hq8
>>11763435Indeed my friend hope to see you here
>>11763368>Reddit’s loosing their shit over all the nazi frogs in spaceThats what would be the most worth it IMO, imagine the sheer butthurt if the chans had swastikas all over orbit. And lets be honest if /k/ is going to make something it will be an orbital defense platform that can also rain magnetic rounds down on earth like in halo.
So what is this thing.
I felt like a genius when I realized that the reason I drop towards Kerbin when I burn prograde while crossing the face of the Mun is because I’m actually burning retrograde.
>>11763464based
>>11763464Landing on the mun is fucked i always wreck last minute
>>11763464The moment where you are able to visualize what's going on in orbital mechanics is enlightening.
>>11763470Orbital mechanics can be so counterintuitive. I was trying to explain to my dad how I could throw a ball down forwards Earth from the ISS and it would end up actually above you and could hit your station again and he couldn’t believe it no matter how hard I tried
>>11763475Just draw the classic 'cannon on a really big mountain' diagram for him, it's the best way I've found to explain basic orbit to randos.
>>11763463https://spaceflight101.com/cygnus-oa7/photos-atlas-v-rocket-assembly-for-space-station-cargo-run/
So is the Orion actually cool or is it junk?
>>11763463Looks like an Atlas V core.>>11763464KSP taught me almost as much about orbital mechanics as my two orbital mechanics classes.
>>11763460I'm a /k/ regular.I'd probably waste most of the money trying to adopt the G11 as standard issue because muh space magic.
https://www.nasa.gov/audience/formedia/features/Advertising_Guidelines.html>Astronauts or employees who are currently employed by NASA cannot have their names, likenesses or other personality traits displayed in any advertisements or marketing material.the video just broke NASA's advertising rules
>>11763482So its a shitty expensive falcon 9?
>On 1 May 2020, NASA awarded a $1.79 billion contract extension for the manufacture of 18 additional RS-25 engines. Ars Technica, in an article published on the same day, highlighted that over the entire RS-25 contract the price of each engine works out to $146 million, and that the total price for the four expendable engines used in each SLS launch will be more than $580 million. They critically commented that for the cost of just one engine, six more powerful RD-180 engines could be purchased, or nearly an entire Falcon Heavy launch with two-thirds of the SLS lift capacity.So this is the power of a nationalized space project.
>>11763468The gravitational acceleration can be surprising. Minmus is probably a better first target.
>>11763490But what was being advertised even? What about all the promotional material NASA loved to broadcast before and during Demo-2?Furthermore it would be the government doing the "advertising", none of this makes sense
>>11763400Why is phosphorous so important?
>>11763490The President as the fount of executive power is not bound by agency regulations. He'd have been fine if it was an official video rather than a campaign spot.
>>11763503So long as anon can into changing planes.
>>11763505it's not the government, it's Trump's campaign. The government doesn't pay for him to advertise his reelection campaign.
>>11763501Meanwhile Elon is pumping out dozens of the most advanced engine ever made for like 1m or something.
>>11763506Necessary element that is a strong limiter because most of the system is poor in it. Earth and Mars are good sources.
>>11763521Couldn't you make phosphorous from agriculture?
Why don’t they use rolls of steel rather than small squares with tons of welding Get a nice big roll, as much as you can fit into 50 tons let’s say, twisting it around a frame Minimize the welding and seams This stacking hoops idea is retarded
>>11763522No, because agriculture needs phosphorus. That's where most of the world's phosphorus goes to.http://www.projectrho.com/public_html/rocket/mining.php#bottleneck
>>11763501"Aerojet Rocketdyne" is a cool name. There's a brand premium for that.
>>11763525>Why don’t they use rolls of steelAren't they? Isn't that what the mass on top of SN4 was, one of those rolls welded together?
>>11763470That’s correct, right? The Navball is by default relative to whatever you’re orbiting, so if you burn prograde at the Mun (or any satellite I guess) when at the half of your orbit that is retrograde to the satellite’s motion, you’ll accelerate away from it and leave its sphere-of-influence, but drop towards the parent body because you were killing off your own orbital energy and slowing down too much to keep up with the satellite, which is why you burn on the daylight side of Kerbin whenever dropping towards Eve or Moho
>>11763501>Meanwhile at SpaceX: Rocket engine go brrrrr
>>11763488>adopt the G11 as standard issueOver my dead body, M45A1 will win any space conflict you soulless commie
>>11763527Where does phosphorus come from?>inb4 brainlet
>>11763525They are. They unroll the steel, cut to length to form the hoop, then do a single weld to turn it into a ring. Starhopper used the individual plates method to construct its hull because the metal was far thicker.The individual plates method will have to stay for now for the pressure domes, its easier to do. I'm pretty sure in the future though once they have the production line going they're going to get a fuckhuge stamping machine and just smash out domes that way.
>>11763533I'm a tad drunk so I think that sounds about right, all I know is that if you fuck around in map view burning your engine in various directions for a while you quickly get a basic feel for how it works, even if you can't describe it fully to someone.
>>11763483Started cool, now with each passing day it becomes junk
>>11763525>Why don’t they use rolls of steel rather than small squares with tons of weldingRolls of steel is what they do use, though.As for why they can't just use a single 50 ton roll, it's because a piece that large would have to be tailor made specifically for the project and also is probably far larger than any mass-produced sheet of 300 series stainless available. Maybe once they bring stainless production in house, most likely not during prototyping.
>>11763475How do natural satellites and asteroids get captured? Every time I do an interception, I have to burn retrograde or do an aerobrake, but Triton is a captured moon and asteroids periodically hang out with earth
>>11763501And that's just the engines, let that sink in.
>>11763464>>11763470>>11763486If you really want to experience orbital mechanics install Principia tho. Or play Orbiter Space Sim if you don't mind not building the rocket yourself.KSP is fun, but it uses 100% patched conics, and that is not how reality works (particularly in systems like earth-moon which are fairly chaotic, not to speak about Jupiter...)
>>11763546You have to be going slow enough relative to the target for it to grab you and pull you towards it.
>>11763546>but Triton is a captured moonIIRC, Triton orbited another body that rammed into Uranus, so the motions are abit more complicated. Also there's the fact that retrograde orbiting satellites can be more stable when captured.>asteroids periodically hang out with earthAgain, retrograde orbits. Also Earth has an atmosphere to slow things down.
>>11763552Orbiter lets you build shit now? I remember following a checklist to launch Apollo 11 in it like 7+ years ago but that's all it was, loading craft other people made.
>>11763541>Where does phosphorus come from?Concentrated forms on Earth? From lifeforms that gathered a bunch of phosphorus themselves and deposited it somewhere. Either when they die (forming phosphate rock) or when they poop (forming guano).
>>11763538>fudds in spaceCringe and cringepilledAlthough really, if you're fighting a conflict somewhere other than Earth, I imagine that you'd want small arms using something other than powder, due to heating issues. Without the air to radiate off the heat, air cooled weapons won't be usable for very long.
>>11763544I can't seem to find much on what makes it so complex
>>11763501>>11763549https://www.youtube.com/watch?v=RhyDY3kuShQWhat did the OIG mean by this?
>>11763483>machining all of that out of a single piece of metalI know the window parts need to be stronger, but holy shit is that expensive
>>11763525Ok let us know where you can buy a custom alloy sheet that is like 70m*27m
>>11763558>IIRC, Triton orbited another body that rammed into UranusI’ve only ever heard the idea that Triton came in alone and knocked all the earlier moons into Neptune. Is there a paper on that? > Also there's the fact that retrograde orbiting satellites can be more stable when captured.Why’s that?
>>11763568I was kinda joking, although space fudds would be kino. I think the biggest problem will be cooling, iSo im thinking we might want to bring back the vickers
I was kinda joking, although space fudds would be kino. I think the biggest problem will be cooling, iSo im thinking we might want to bring back the vickers
>>11763568Gunpowder is fine, or at least the alternatives are worse (lasers and railguns already want to melt themselves on Earth). Modified rifles with heat pipes and radiators, you're good.
>>11763582If cooling is an issue, maybe tensile force can be revisited for killing folks, space-crossbows and shit.Obviously shit like rubber is out, but what other materials exist that have elasticity at vacuum temperatures?
>>11763561No. That is what I meant. You still need to use mods (or make them but that takes skill)Principia is an add-on for KSP that introduces N-body physics.Just to put things into more perspective:In our solar system, in transfers to the Moon you can get in trajectories where the pull of the Sun becomes more than two times that of Earth. Essentially "orbiting the Sun more than you do Earth" It is simply too much to accurately simulate with patched conics.I don't know about the Kerbal system because I do not know the numbers, but I am sure it will also be significant.
>>11763590The steel pill strikes again.
>>11763590Well modern crossbows are make with basically cable so that'll work.
>>11763587I was wondering how efficient radiators could be in a vacuum or near vacuum.The good news is that if you're in 0.4G you can pack a heavy ass system with no difficulties.Also, external ballistics would be different because little to no air drag and terminal ballistics would be different because anybody whose suit fails gets automatically sent to the shadow realm.My personal theory is that flechettes fired by CO2 would be a good idea, but the low temps might make that implausible.
>>11763590Can you "shoot fire" in space? Like if you lit a sphere of gasoline + oxidizer and set it in motion?
>>11763249That's literally the stupidest idea I've ever heard.
>>11763600If they work in vacuum, cool. Wooden/plastic bolts might have less of a chance of hull-breach than a metal one, a crossbow will shoot whatever ammo you want.
>>11763580>I’ve only ever heard the idea that Triton came in alone and knocked all the earlier moons into Neptune. Is there a paper on that?Your theory seems to be more accepted. What I said seems to be just a passing idea.>Why’s that?There's lots of complicated explanations about it. The simplest I can describe is that tidal bulges of a planet due the gravity of it's moons also pulls on all of the moons in the planet system. If the moon is orbiting prograde then it'll spend alot of time near those bulges as it orbits, thus being gravitationally more affected by said bulges than retrograde moons which would spend less time near those bulges due to passing by them much more quickly.
>>11763233> low-effort transport It's not going to take long for you to end up a weak low-effort person on Mars though. This only really applies to fresh Terrans who've travelled in 1g conditions for the last 7 months. I guess air resistance might make it a bit better.
>>11763617Why not create reliable slingshots?
>>11763602Radiators will be smaller than the ones you need for the astronaut anyway, because they can run hotter. Combat zero in free fall or low-g with no drag is basically point blank at any distance you want to use small arms at, although it could get more sophisticated than that. Getting a pinhole in a suit is not a death sentence with egress, focus should still be on damaging the meat inside.
More Orion discussion
>>11763629There are more cheaper cross/bow-friendly materials than there are for slingshots. Rubber is absolutely out.
>>11763629Slings certainly can be lethal, with either stone or metal slugs and good aim. I wonder if the slingshot has been developed much beyond the basic wrist-rocket? Could you make something approximating a handgun based on the same mechanic?
>>11763561>>11763596PS: most of the fun in orbiter comes from recreating historical or future missions (with very good accuracy, down to the kilometer perhaps, either flying them manually or using autopilots), using real spacecraft in unintended ways (try for example doing a lunar flyby with a crew dragon), and planning complicated trips with real or fictional vehicles.There are very good add-ons like IMFD or TransX that allow you, thanks to the realistic physics, to design Voyager-style flight plans.Slingshots work, Lagrange points, everything.Principia for KSP introduces Orbiteresque physics. Not sure if it is as accuarate, but a good tradeoff maybe.
>>11763579I make them in my backyard, special alloy recipe too, 50% stronger than any known steel
>>11763522Phosphorous is an element. You cannot make it. You can only use what you can mine. Phosphorous is the rarest of the 100% no-way-around-it vital elements to Earth life (DNA uses phosphorous for its main structure). This means that no matter what other hurdles we overcome, how far we go, what places we colonize, etc, there will ALWAYS be a relative scarcity of phosphorous. Recycling it will be paramount. Phosphorous will be far more valuable than gold or platinum or diamonds or whatever. It will be so important to all humans and so coveted that accidentally dropping significant amounts of phosphorous into places where it is hard or impossible to retrieve (into Jupiter, into the Sun, onto a neutron star, into a black hole) would be an egregious crime.
>>11763630I think an automatic firearm produces way more heat than a human.Human body heat is equivalent to like a lightbulb. Throw in the various mechanical shit and the suit and it's still a lot less than mag dumping an AK.
>>11763652High instantaneous heat is the ideal case for radiators. They're much shittier at getting rid of the kind of constant low-level output you get from meat.
>>11763541>Where does phosphorus come from?Fusion reactions inside giant stars billions of years ago. Phosphorous will be extremely expensive in the future because it will be scarce if we can't make it, and even if we can somehow make it using extremely energy intensive means like particle accelerator fusion, the sheer amount of effort required to produce a single gram of the stuff would mean it would stay just as valuable, if slightly less scarce.
>>11763631Why ESA loves to be NASA's bitch? They had the opportunity to develop their own spacecraft but as soon NASA threw a bone to them they rejected the idea.
>>11763656Interesting.Then the idea might be some kind of belt fed 6.5 with massive amounts of radiators.Also, full body ballistic shielding might actually be viable when the gravity is super low and everybody is wearing space suits anyway.
>>11763556No, you need a third body to exchange momentum with. Doesn't matter how slow two bodies approach in space, they will escape each other again unless there's a third object to interact with. In Triton's case we believe it had a companion object (just like Pluto has Charon), and when the pair encountered Neptune the companion was accelerated away into interstellar space while Triton was left behind and captured. As for objects that get captured into orbits around Earth, you can thank our own big ass Moon for that.
>>11763558>Also Earth has an atmosphere to slow things down.Irrelevant. Earth has a big ass Moon with big ass moon gravity to yank on an asteroid and slow it into a briefly stable orbit before it inevitably encounters the Moon again and gets shot off back into interplanetary space.
>>11763290>ultra boom
>>11763571>I can't seem to find much on what makes it so complexThe engineers and designers made it complex, anon. They made it complex for various reasons I'm sure, probably to do with optimizing for strength and weight, but they really didn't need to. The decisions they made were approved by managers who wanted to make more mmmuney $$$$
>>11763652adults are about 100 watts, grub stage humans a bit less
>>11763666Self-supporting ballistic shields akin to stabilized camera mounts, supporting maneuvering thrusters and stuff that would normally go in a back rig. Really more a spacecraft with a human attached than infantry, but shit's weird in space.
>>11763667>No, you need a third body to exchange momentum withDid the 'second/third moons' interact with the main Moon to get captured? I was under the impression that if their speed was slow enough relative to us, Earth's gravity would overtake the pull exerted by the sun and tug it our way, possibly into an ecliptic orbit that settles out more regular over time.Or I'm high and dumb, I concede the possibility.
>>11763464someone please explain. face of mun? so in orbit around mun?
>>11763667> As for objects that get captured into orbits around Earth, you can thank our own big ass Moon for that.Ah, gravity braking. Giga-chad Tylo has saved hundreds of thousands of kilometers per second of delta/v by now I’m sure
>>11763249Holy fuck are you me? I literally daydream about Space missions and alternate space history 24/7>Writing a short story about DIRECT>Made a technical report about a comet Sample Return in an alterna 2019>Manned Mars mission by 2039 but with DIRECT insteadEtc etc etc
>>11763578Is it actually machined from a single giant chunk though? I thought for parts like these it starts out flat and they bend it into a round shape bit by bit using a brake press or something.
>>11763603sounds like a rocket engine to me
>>11763677>ecliptic orbitEccentric orbit, blame the booze
>>11763673I was imagining specific infantry scenarios. For example, you're storming the Chinese Mars base, and you need to clear out the catacombs underneath.For actual zero g it'd be like air or naval combat in that nobody gets out of the ships for any reason.
>>11763651Could chondrite-like asteroids be a good source of phosphorus? I am reading some data and the concentrations seem to consistently be around 1000ppm (on mass). More abundant than titanium for example.The human body contains around 1% so the equivalent to 1 ton of those meteorites.
>>11763680I meant the face of the Mun visible from Kerbin’s surface. It’s tidally locked like Luna, so if you’re in a prograde orbit around Mun or Luna, and you’re crossing the face of the body from the perspective of Kerbin/Earth, you can burn prograde at that time and drop towards the parent body. If you burn over the side facing away from the parent body,the “dark side of the moon”, you’ll go into an even higher orbit than the satellite is at once you leave it’s sphere of influence. You’d do the same in LEO if you want to go upwards from the sun towards Mars or beyond, start your burn on the night side.
>>11763695Boarding actions will still be a thing. Infantry doesn't have place in all-out war but that is not the normal state of affairs.
>>11763637You can make a slingshot out of the same material as a crossbow. A sone won't have the same penetration
>>11763663Because their countries won't give them funding. NASA likes international cooperation so they offer everything to ESA. Otherwise the ISS would be Russia America and Japan
>>11763640Probably, just make it slower and larger than a bullet
>>11763558>IIRC, Triton orbited another body that rammed into Uranus, so the motions are abit more complicated.Triton orbits Neptune, and it does so in a retrgrade orbit. It was likely part of a binary pair (Think Pluto-Charon) and on encounter with Neptune interacted in such a way that one of the pair got shot off into space while Triton captured around Neptune.
>>11763702oooooh it just clicked, I had the mun rotating the wrong way, but because it's locked it rotes CCW in this pic. so prograde on the 'bottom' there, earth-side, is retrograde for earth's 'orbit' that you're not-really in. something like that.Man I need to play KSP again, I stopped playing soon after they *added* the mun lol
>>11763704I can't really see a reason to do boarding actions in space. In symmetrical naval warfare you just absolutely rape everything with missiles from BVR.The only time you board a ship is in case of pirates or drug smugglersSo in other words, not until the space wolves show up.
>>11763710The mechanisms are completely different. I would love to see your slingshot powered by wood, steel, plastic or carbon fiber in place of rubber
>>11763721>I can't really see a reason to do boarding actions in space.They have a ship, you want that ship. Simple as.
>>11763669Fucking kek
>>11763724Yeah, but you have to match orbits, and somehow prevent them from making tiny orbital adjustments constantly.Docking is hard enough already when both parties consent. If you're trying to space rape somebody it'd be damn near impossible.
>>11763721>I can't really see a reason to do boarding actions in space.>The only time you board a ship is in case of pirates or drug smugglersSo you can tho.Like I said, not during actual conventional engagement but that will be exceedingly rare. The glorified coast guard will be the only guys actually seeing anything like action.
>>11763720You are still playing a toy model. As I warned above, patched conics are not the full story. In an orbit like that, for better accuracy, you should consider your trajectory to be relative to the barycenter of Kerbin, Mun and the Sun, -at that particular instant-. That is if KSP had realistic physics.For patched conics your new understanding might be enough.
>>11763720Oh shit that totally makes sense. It’s easier with a picture. Yeah I can get to orbit in KSP and I’ve gotten to the Mun by lucky burns, but I really lack the fundamental understanding of how to get into specific orbits, other than Kerbal adjustment orbits. The idea of planning a Mun landing or even simple rendezvous is so out of my league. Also fuck me the thought of landing a space plane on the runway seems IMPOSSIBLE
>>11763671Yeah, there is absolutely no reason the payload on the SLS with over a decade of development should be a fucking 4 person capsule.
If funded the constellation program would have been great
>>11763739Much better than sls
>>11763732I learned how to do that shit by watching how Mechjeb did it, and then aping it. Eventually I got experienced enough to not need mechjeb anymore.
>>11763728It could work if you disable their engines, or brick their ship some other way. It would be easier to just poke holes in the hull and wait out the people on board, but that could take too long. You want your piracy to occur before anyone can get a ship or missile to your location.
>>11763738>hey /arg/ did I cut enough speed holes in my billet lower yet?
>>11763739>>11763742That yuppie nigger did it.
>new Scott manley video about NASA's path from the shuttle to now>completely glosses over the funding cuts from 2008-2016He's really skirting the line there, he is normally good at keeping his biases out of his videos.
>>11763732Just get to orbit in a cable vessel. Then set a waypoint on your orbit and adjust it until it sends you on a trajectory passing about 100k km from the mun. If you are playing career mode, you might need to upgrade your tracking facility until you have the capability to set maneuvers like that.Its pretty easy if you just click on the blue trajectory from the map line and add waypoint.
>SOIboi vs n-chad
>>11763750He's been in full ORANGE MAN BAD WE MISS YOU OBANANA mode on Twitter lately. Guess it leaked through.
>>11763750he showed a graph and said NASA was underfunded, fuck off
>>11763750Most YoutubeTards are doomed to become cowards. He will not blame a nigger.
>>11763755I'll rewatch it but i don't remember that. I do remember him praising the council and talking about spacex for half the video.
>>11763757>>11763753Its really not even about what his politics are its just sad to see someone who is normally objective becoming less so due to politics.
>>11763759literally at 11:15>they had expected launches as early as 2015, but the continual underfunding made those untenableassociated with a graph showing how none of the budget requests between 2011 and 2015 were properly funded
>>11763764That is talking about the underfunding of constellation, not about the underfunding of NASA as a whole...
>>11763774which is the only relevant part of the history of manned spaceflight in America that the video is chronicling.
>>11763774I should add i think the underfunding of NASA as a whole is important to bring up because it brought a lot of challenges to everything space related, not just constellation.
>>11763775Hardly, there was a lot more than what he covered. Also why nothing about the soyuz?
Obama good orange man bad
Jupiter Icy Moons Explorer. Any updates on it? Its the only ESA program that im excited about.
>>11763783Also Europa rover when?
>>11763783Launch in may 2022, not much else. If everything goes as planned. Afaik.I also like this mission.Jovian moons are interesting. Haunting for some reason. I once dreamed I walked on Callisto.
>>11763571thank goodness they have their masks on. wouldn't want the rocket to catch covid-chan
>>11763804Yeah same minus the dream. We really should examine those moons and juice should give us some good info. I want a probe though I think there is life on europa
>>11763720Yes, exactly. If I remember correctly, the Apollo missions went into retrograde orbits so that if something went wrong, and they didn’t perform the deceleration burn, they would go back to Earth after they left the Moon’s sphere of influence rather than sailing off into the interplanetary void https://en.wikipedia.org/wiki/Free-return_trajectory
>>11763822Europa Clipper is also scheduled. It should launch 3 years later but will arrive at the Jovian system at roughly the same time as JUICE.
>>11763841God damn i wish i was on that project. That patch is so cool.
>>11763541It generally weathers out of phosphate minerals like apatite.
Where exactly would you want to live on Mars? Valles Marineris looks awesome to me
>>11763883My question is why the hell we havent sent a rover or lander to Valles Marineris in the first place.
>>11763894No clue. Must be interesting geology
>>11763894Somewhere with caves and lava tubes to explore.
>>11763233Mars' surface is covered in regolith, which has a consistency between fine gravel and dust. Unless you find a particularly rocky area, you as well be riding a bike in a desert.
>>11763894Have you seen our rovers and delivery systems? They suck ass at navigating rough terrain. Valled Marineris is deeper than the Grand Canyon. That's going to need firsthand exploration.
>>11763911There’s gonna be aliens down there
>>11763922Make a rover that isn’t dogshit.
>>11763932Harder than it seems. We are limited to what we can program. Also Valled Marineris cuts deep into the rock and offers a free peek into geologic history, but it’s hard as fuck to land there and it would be almost impossible to communicate with a relay satellite, much less direct communication with Earth using a high gain antenna
>>11763779Soyuz isn't relevant to the story. The US wants an independent crewed capacity because it wants to be a major player in space. The last time it was between systems, there was also a years long gap between launches.Only difference is that the US had an alternative to simply not sending anyone up.
>>11763739>If funded the constellation program would have been greatSRBs as a first stage is such an awful idea. Astronauts would die of embarrassment if nothing else. Orion wasn't ready, and would still be an overexpensive "solution" for reaching the ISS.>A review of experts concluded that it would cost $150 billion for Constellation to reach its destination close to the original schedule. The Obama administration instead canceled it.>Much better than slsAs per the Augustine Commission, Ares V would not be available earlier than SLS, even with unconstrained funding.Similarly, Ares I would not have been available earlier than Commercial Crew, even with unconstrained funding.
>>11763976>>11763739>>11763742SLS looks like they just skipped to ares 3
>>11763976>SRBs as a first stage is such an awful idea. Astronauts would die of embarrassment if nothing else. What about space frogs? A Karman line hop with an SRB should be doable for a frog and a parachute.
>>11763976what's so bad about srbs as first stage?
>>11763714NASA only offers leftovers. ESA was in conversations with Roscosmos for jointly developing a new spacecraft. But guess who didn't liked the idea?

How big is jupiter in the sky from its various moons?
>>11763435It is a shame they’re so keen to retire it.
>>11764007I would envision planetary ground invasion being only doable and necessary against an Earth like planet with a protective atmosphere and a decent amount of planetary defense keeping orbiting warships at bay. The way I'd invade a planet would be to do a "pump and dump" landing where dropships along with a shit ton of decoys are released from carrier craft that are just on a "skimming" trajectory and not in orbit. This forces land with the goal to be to take control of enough ground surface to enable warships to position in geostationary orbit without the risk of having shit being shot from directly below them like lasers and particle beams and shit. Making it much more doable to keep ships in orbit to commence, or at least threaten orbital bombardment through the use of casaba howitzers to conquer the rest of the planet. Due to the amount of ground you'd have to invade and conquer would be huge, you'd probably require at the very least, an entire Army group to multiple Army Groups to succeed. Not only that, but you are also racing against the clock to conquer enough ground to get the warships in a safe geostat orbit before the enemy maneuvers dozens of Army Groups from around the world onto the continent(s) that your Army Group(s) are on. All of this of course being a potential what if situation of an interstellar civilization that's disregarding how interstellar travel is done which could drastically change what I just said in this post. Anyways, just thought I'd give my own autistic idea a chance.
>>11764023It really is something else to watch two boosters land at once, but I think there will be plenty of awe when superheavys and starships start landing everywhere, the fucking absolute units
>>11764029SuperDuperHeavy direct Mars insertion flights soon.>five first stages
>>11763998For Ares I, SRBs can not be throttled or shut off. If something goes wrong, you are effectively stuck until it burns out. SRBs have low specific impulse, which is partially why the Ares I models have those huge upper stages, even for operations to LEO.IIRC SRBs for Ares (and SLS) would still be made at that plant in Utah, which limits the diameter of the SRB to that which can pass through rail tunnels, which limits total impulse, again forcing a larger upper stage. Even when Nasa was designing the thrust-assisted orbiter shuttle, they wanted liquid boosters but had to do solid because development costs would be lower.It would still be subject to Nasa and contractors' high fixed costs.
>>11764038What a weird looking thing. I know of no other launch vehicle that gets so much wider at the second stage. They’re either the same diameter or smaller typically
>>11764027If you are stuck with chemical or similar propulsion, interplanetary war to Mars will probably be too hard to justify. You can only move forces every two years and they take 3-6 months en route, 45 minute time lag, no resupply, no refuel unless you can seize a fuel depot, etc...Organising a war like that at our current technology is laughable. Whoever is being invaded will win so long as Mars has infrastructure to build a basic level of weapons. Situations very similar if not worse for other planets. You need a torch drive to engage in a proper interplanetary war.
>>11764045Without shifting production from Utah, they're stuck at 3.71 SRB diameter so the only thing they can do is add a fifth segment to make it taller.The Ares I upper stage was inspired by the Space Shuttle External Tank and the Saturn IVB. It has about the same volume as the S-IVB, and an engine from the same J-2 family. Between those, the result being this tall, interestingly proportioned rocket.
>>11763976>As per the Augustine Commission, Ares V would not be available earlier than SLS, even with unconstrained funding.>Similarly, Ares I would not have been available earlier than Commercial Crewhow the hell does that work when Starship is gonna be ready in a few years and ELON MUSK MADE IT IN TEXAS WITH A BOX OF SCARPS!!!
>>11764027You would need a few billion men
>>11764078>from the same J-The Ares V would have been so good
why not just launch a rocket and put a bunch of earth dirt on marsthis idea came to me when i noticed falcon9 looks like a dick
>>11763546As far as I understand, usually through third body interaction
>>11764078>>11764125>>11764115I'm gonna say it...The Ares rockets were beautiful though. I remember going to "Space Camp" back in 2009 before they were cancelled and we watched a documentary on Ares I and Ares V. It was really exciting. When I learned it was cancelled I was still a kid and I was very very upset. It wasn't until two or so years ago that I learned that Constellation wouldn't have worked anyways - even with unlimited funding - as the designs were just flawed overall.What SHOULD have happened was certifying Delta IV Heavy to carry Orion, or an Atlas V Heavy. Commercial contractors build the Crew rocket, while NASA uses something like SLS but with a balloon upper stage. Can hold something like 350 tons of propellant at one 27 metric tons and two J-2X's.Ah well.. one can dreamDIRECT is pretty cool though. I typed up an alternate history mars architecture that made use of DIRECT and was technically conservative too, It had no zero bailiff tanks, no NTR, not even ISRU. It was a cool writeup.My ex set it on fire when we broke up. But I still remember 99% of the math.
>>11764125Is this a meme or is this true? Some people are so adamant it would have been worse. How fucking hard is it to convert the shuttle’s External Tank into an extended stage and stick a second stage with a capsule on top>>11764115Government. Imagine having your rocket built by the local DPS/DMV, vs. having it built by hardcore enthusiasts who get to change what they want when they want
>>11764120A few million would suffice.
>>11764136Ares V would have been cargo, Ares I would have been crewed. SLS is designed to do both. It’s still a piece of shit though that has gotten bogged down in politics (I like the DMV comparison lmao). After looking at Starship and reusability, I can’t help but look at SLS and fucking cringe. It uses Hydrogen, It uses SRB’s, it fucking eviscerates 99% of its own weight because it’s expendable, and it was supposed to be a cheap use of shuttle tech but it’s been in the works forever and we’ve only gotten one flight from Orion so far and IT WASNT EVEN ON AN SLS. I wonder if Jim believes in it or if it stresses him out at night and he just wants to kill it and rely on Starship for the latter half of Artemis’ life cycle.Also when the fuck are other companies (including NASA) going to start utilizing reusability. At first it was a meme but Elon has changed the game and set a new standard imho
>>11763949It's deep, but it's also super large and the cliffs aren't vertical so there wouldn't be lots of LOS problems. You can check altitude profiles here: https://trek.nasa.gov/mars/ (if the website unfucks itself). IIRC, Marineris was one of the possible landing sites for Mars 2020, but the previous rovers couldn't land precisely enough.>>11764063>Whoever is being invaded will winDepends of your definition of win, Mars bases will stay ridiculously fragile for a long time, except if deep underground: just throw a volley of missiles (nuclear if needed), and you've killed all these Martian revolutionaries

>>11764202Okay bud tell me how you plan to conquer a planet with 1million people

>>11764210By doing exactly what I said in my original post.
>>11764210Nuke it until there’s only ten people left
>>11764222KinoMachining (?) all this shit must be a PITA though
>>11764223>>11764235Yeah your post didn't say shit and you are retarded if you think 1million troops is enough
Apparently Chinese carmaker Geely is building a LEO constellation to support it's driverless cars. The first satellites will be sent to Jiuquan this month.
>>11764248Sounds like a meme honestly
>>11764245In Star Wars, there were only a few million clone troopers, which is absolutely fucking ridiculous and insufficient to wage war in an *entire galaxy*. On the other hand, the Separatists were once quoted to have “quintillions” of Battle Droids, which is much more feasible.
>>11764252Maybe it's the best way for them to go? Or maybe they are backed by the government and there is more to the constellation than they are saying?
>>11763249I have vague fantasies about living in hyperadvanced rotating habitats like those in The Culture.
>>11764266>maybe they are backed by the government and there is more to the constellation than they are saying?That I'll believe, yeah. If Starlink does work, there will probably be similar systems from Europe, Russia and China, like for GPS
>>11764245Check your reading comprehension before you post some gay shit nigga.
>>11764259Just for some context here, the initial invasion of iraq had just under 310,000 personnel on the coalition side against an iraqi force of about 1,300,000. And that was a large technological and training advantage shared by the coalition. But that guy thinks a force just 3.3 times that initial coalition force is enough to take over a force 6000 times that of the Iraqi force. Which by the way is probably going to be a near peer adversary.
>>11764282If Reticulans invaded I think they could take over Earth with about 5000 dudes
An article about the Geely LEO constellation https://rntfnd.org/2020/03/05/commercial-chinese-leo-pnt-launching-in-2020-spacewatch-global/It says that position/navigation info is the main function but that it won't just focus on cars, but on other unmanned vehicles too. Military drones? The article also mentions that the US military has been interested in a similar capability.
>>11764274Or you are just retarded, see >>11764282 If you think you can cover any significant ground on a planet with just a million people the you are retarded.
>>11764290So we are resorting to pure fiction,?
>>11764303Reticulans are real we just have no real idea of their offensive capabilities
>>11763468Just minding you don't come in too hot and at an angle is the trick. Learning the Navball in all its crappiness helps a lot.
>>11764295Yeah, and we had only 8 million during WW2. The fuck is your point? My point still holds true. An Army group to multiple Army Groups is what would be required.
>>11763249Call it Anusian Lighthouse and we have a deal
>>11763991That is exactly what they did. Constellation got taken out behind the building and shot in the back of the head, the designers went to the drawing board and waited for a change in the political climate because what else could they do?In comes a president who wants to do a grand gesture.Bam, same program is reborn with a slightly modified rocket using the same parts and a new name.
>>11764236Computer CNC does that shit. Inspecting it afterwards is the pain in the ass.
i wish i had a cnc machinei would have made smol rocket
>>11764325I wonder if SpaceX will eventually do this kind of stuff to shave more mass on Starship, it would kinda defeat the simplicity of "just welding steel rings together" but they'll really want less mass on Starship
>>11764369What are they using again? 4mm cold rolled steel? Not much to mill out there, man. You can guarantee that the Aluminium alloy F9 stuff is milled out in the same way though to cut down on weight where they can to keep strength though.Completely different beasts.
>>11764371>You can guarantee that the Aluminium alloy F9 stuff is milled out in the same wayiirc they stir weld all the stringers or something.Pretty sure they don't mill them anyway, it's ridiculously wasteful and would balloon the cost.
>>11764402The inside of the tanks and whatnot are most likely milled out to make them lighter while maintaining strength. The fact that they're friction welded together is something completely different. They don't mill them out of a single block, don't get me wrong. That was not what I implied.
Like the slow decay into disorder occurring in the universe these threads turn to veritable diarrhoea. >>11764223>>11764156> just throw a volley of missiles (nuclear if needed)"Just throw" something that people have months to prepare for at worst.Please do not join the actual military bro.
>>11764405>The inside of the tanks and whatnot are most likely milled out to make them lighter while maintaining strength.Nope. They actually use stringers and runners.
>>11764408>pops out of subspace behind youheh, nothing personell kid
>>11764412Ah, ok.
>>11764405>The inside of the tanks and whatnot are most likely milled out to make them lighter while maintaining strength. The fact that they're friction welded together is something completely different.That's what I'm talking about though. Milled isogrid is stupid expensive and you can get most of the benefit from welding without it. >SpaceX uses an all friction stir welded tank, the highest strength and most reliable weldingtechnique available. >Apart from its enticing features, the isogrid structure is extraordinarily expensive to manufacture. The commonly pursued route to manufacture such a structure is to start from a thick piece of metal and machine it down with a computerised numerical control. This technique leads to a waste fraction of 95%. For this reason, SpaceX did not use the typical isogrid structure, but obtained a similar effect with stir welded strengthening stringers.
Elon is dispensing redpills again. This is why all those "why dont fix Earth before we go to space" idiots are wrong. We dont know how long the window of opportunity to colonize space will last. Lets do it sooner rather than later, because it might be too late.
is that meteor recovery mission permanently shelved?it's one of the better/interesting ideas NASA put put out
>>11764405>>11764412There's some milling on the second stage, you can see the patterns here https://twitter.com/elonmusk/status/875849793204928512?s=20
>>11764437that's a terrible way to argue against "why don't we fix Earth first." The real argument is that "fixing Earth" is a moving goalpost that can never be satisfied. The human race is never going to think it's done fixing itself.
>>11764437A global collapse resulting of climate change is not a redpill but common knowledge everywhere but on this board, homo sapiens existed for 200 000 years at most, half a billion year is a number so big humanity will not exist because evolution and technical progress are real things. Understanding how to live on mars and the science behind the planet will help us to fix our shit there anyway so space exploration is win win, if you want to take money from somewhere try useless and polluting corporations like mcdonald before space shit.
>>11764468That are welded mounted points for ring stringer structure and longeirons also welded into that this is not any form of iso/ortho grid
>>11763812I actually fear a mission like that.Unless we develop a safe way to absolutely sterilize the probe we shouldn't even think about sending anything there.We could risk to lose the only alien ecosystem we will ever be able to put our hands on.
How the fuck do I get to dres? I know the phase angle,ejection angle and the velocity I need to be, but I can never get an encounter when I try to match the planes later.
>>11764437What the fuck is with Elon's raging hard on for mars? Just make a bunch of perfectly habitable oneill cylinders or other space drums. Seriously I don't believe Elon just doesn't know about building space habitats, did he adress it at any point?
>>11763233>fine, dusty sand>low-g pulling you downyou'd have terrible grip, it'd probably be an awful experience. Maybe if you had big old strakes on the wheels it might be okay.
>>11764693>orbital-first faggotsNo. Mars is already there with all of the necessary resources and an easily navigable gravity well. Colonizing Mars and the Moon is a much faster way to get gigatons into orbit than trying to do it directly from Earth.
>>11764693Because people want ground under their feet. O'Neill cylinders is more far fetched than a Mars colony with our current technology and nobody wants to live in fart boxes in the great black inhaling recycled rectal fumes for the rest of their lives.
>>11763546triton was in a binary pair of kuiper belt objects, the partner was flung off into interplanetary space or collided with neptune, providing the impulse to get triton captured. then it circularised more due to tidal effects, i'd imagine. here's a good video on it:https://www.youtube.com/watch?v=oBunWOUJlUA
>>11763201Let me take a shot at making this is manageable. Bigger planet means bigger opportunities. Your brain can't react because it doesn't understand. The Earth is overpopulated. You can't run. That's what the smoke said. See where I'm getting at. So how do you expect different wavelengths, microorganisms and new elements to appear. I gave you enough to traverse all of the universe and you spent it on killing yourself. Cum re-imagined. Modern fossil fuels and particle accelerators. Fun work you're doing. Even our president joined in. But he wants to pay me to make room for his kids.
>>11764161>Starships and their crew sacrifice themselves, detonate the tanks in LEO.What about stopping the bad influence of islamic terrorism and thinking about an escape before the explosion?>>11764205The kessler syndrome. Whoever does it first cuts it opponest away from accessing space.If you really want a cool series forget suicides and think about doing it at the same time by chance, both crews can't go back to their planets and they must unite forces to survive even if they were enemies.
>>11764701>Because people want ground under their feet.Weak people, but those are the same guys who will remain on Earth anyway.Real spacemen will inhabit space itself and laugh at you puny earthlings.
>>11764733Yes, just what these threads need, more stupid memes and less reality.
>>11764693spaceX is all about PR, you try explaining to the general public the principle behind o'neill cylinders. There just isnt the cultural background to do it, as opposed to "MARS GOOD", which people can get behind and support.
o'neill cylinders would require decades of R&D—we already have all the technology needed for a bunker base on Mars.
>>11764729>Whoever does it first cuts it opponest away from accessing space.Nah, stable orbits maybe, but it will always be possible to send something through in a direct escape trajectory
i've been learning a lot of space-related things from these generals, thanks anons
>>11763677>>11763693It doesn't matter what velocity your object encounters Earth, it will be on an escape trajectory, because orbits are always symmetrical and it's coming in from interplanetary space, so it's going to end up leaving back into interplanetary space again, unless it interacts with a third body to lose energy from its orbit.
>>11764749Ignore the Oneill cylinders nutcases. They're talking about timelines in the 100s of years. They're bozos. Mars can hold 100+ people in potentially a decade or so of hard work.
>>11764828Then how do bodies with no moons capture anything?
>>11764437>>11764470Going to Mars is how we are going to fix earth. Most saliently, how we handle climate change and other human environmental problems.I’ve said it before and I’ll say it again. Mars will never be green, “terraforming” that place is a fucking meme. Mars is going to be a foundry planet that we export all of our nasty industrial processes to. There’s no EPA, there’s no environment to fuck up. We can dump waste wherever we want, run everything off nuclear power, and smash asteroids into the surface for processing of their precious metals. Meanwhile, back on earth, we “terraform” our existing habitat into an agrarian garden of eden. The whole of the earth will be almost exclusively for habitation and food production, which is a much more realistic outcome than trying to put a fucking magnetosphere around a dead planet.
>>11763697It really wouldn't matter if there were a type of asteroid made 100% of phosphorous, because in terms of the entire solar system's mass it is very rare. It's going to be the limiting factor that human populations run into when we're building a Dyson swarm of habitats.
>>11764733Enjoy your jellybaby's.
>>11764836It will never be cheaper to make something on a planet and transport it to another planet to sell. Asteroids will be much more convenient foundries, since you only need to go down gravity wells. And even then, barring insane environment regulations, it would probably still be cheaper to produce locally
>>11764839Nah I'll enjoy my healthy 1G(or more, I can do whatever the fuck I want) bred babies while you grow some mongoloid 0.4G acclimated bitch with the bone structure of a house of cards
does spaceX impose a limit on how many times they will use a rocket before retiring it? The starlink mission the other day was what, the 5th or 6th flight? Do they cap it at 10?
>>11764852>It will never be cheaper to make something on a planet and transport it to another planet to sellWrong. Environmental compliance to do business here on earth is a massive overhead burden and even if you only just break even, it’s still worth doing because you aren’t shitting up the Earth with whatever residual pollution and carbon footprint is left over.
>>11764829>100s of yearsNot even(what is automation for 400), but even if it is 100s of years we're talking about the terraforming of mars here which is arguably going to take much longer. Is /sci/ actually /sci/ or just mouthbreathing retards, seriously. I like Elon, but god damn please get off his dick it might break.
>>11764868>muh terraforming Dumb retard
>>11764861no, but they also don't want to jeopardize payloads by pushing the boundary. The reason all the reuse records are broken on starlink launches is because it's internal and not precious cargo so they can push the limit and see how far they can go. Things like crewed missions will always be first-time boosters until they have mountains and mountains of data precisely detailing the limits and effects of reusing boosters.
>>11764078How did Ares I get past the design stage and actually fly?
>>11764852And remember that no environmental restrictions goes all the way up the logistics chain. Imagine how cheap a nuclear reactor would be to build and operate if you could just throw out most of the restrictions that we have here on earth. If you melt down a reactor on Mars, who gives a fuck? Bury the fucker and build another one a couple miles away.
>>11764862The thing is, the world is not one country... I don't see regulation blowing up prices to the point where deep space or even orbital manufacturing becomes competitive for staple products globally.
>>11764693If we can't even turn Mars green with life yet, what makes you think you can just make a habitable giant tube for people to live in? You have to take steps nigga
>>11764855You won't be laughing because you're puking from insufficient size. If you're gonna live orbital, at least live somewhere that isn't utterly retarded, like a Von Braun Station. That shit is at least somewhat viable in today's economy.
>>11764010Large but not overwhelmingly big.
>>11764892It wouldn’t be all products. And it wouldn’t even be complete products that get made off world. Just the nastiest ones and only the process steps that are heavy polluters. Final assembly/packaging would/could still be done here. Semiconductors and battery manufacturing are two industries off the top of my head that have enough environmental restrictions globally that they could be profitable from off world production.
>>11764900>insufficient sizeWhat do you mean, insufficient size?

>>11764900Dude I'm sorry but you just don't know what we're talking about here.
>>11764895Why do you think making our own environment on a very small scale is less feasible than terraforming an entire planet?
>>11764468I see what you're seeing, but milling a plate of aluminum flat by taking off ~3 thou using a 4 inch wide bit is not as expensive or time consuming as milling 500 thou deep triangular or square holes into an aluminum plate.
>>11764953I gotchu anon.
>>11764861they haven't reached 10 so nobody knows.presumably they'll keep pushing them with starlink payloads till they break
>>11764686Use the old overshoot-and-adjust method, where you wait until the end of the launch window, then get onto a trajectory that takes you further from the Sun than your target, do a mid course correction to get into the same plane, and then a final course correction to adjust your apoapsis up or down in order to fine tune a perfect encounter.Advantages; piss easy, works every time. Disadvantages; you need more delta V than a single-burn autistically calculated departure from Kerbin, but those aren't any fun anyway.
>>11764872Oh, what? Biodomes? Bunkers? Biodomes are basically the same tech as making orb habs but on a planet with a significant gravity well that's far away from usBunkers are all well and good, but we're talking about Mars in the context of colonization. When we have bunker cities on Mars that house a couple hundred thousand souls we have already made plenty of orbhabs.
>>11764978thank you my jogga
>>11764989>When we have bunker cities on Mars that house a couple hundred thousand souls we have already made plenty of orbhabs.>Make some pressed bricks and a trench and pressurize it>this takes longer than making an o'neill cylinder somehowNo lol

>>11764693Mars has the low gravity you need to make space travel cheap and easy. From Mars, colonizing the asteroid belt actually makes sense instead of requiring a million assumptions and esoteric economic theory to justify doing it from Earth. Obviously colonizing the asteroid belt requires you do spinning habitats from gravity. From there humanity will increase and the default lifestyle will be that of a person aboard a rotating space habitat. Consequently, colonization of the entire remainder of the solar system will follow, and interstellar colonization fleets departing for other stars will become routine. You need Mars first though, to do this. In fact Mars is so perfect it's arguably spooky that it exists. Mars has the perfect amount of surface gravity, strong enough to keep people healthy and not clumsy, but weak enough to make space access really easy. Mars has an abundance of all the elements we require to grow food and to supply our industries. Mars even has two asteroid-like moons for us to practice mining and to exploit for materials to build large orbital rotating habitats. Rare Earth hypothesis? Hardly, basic life is probably common throughout the universe. However, intelligent life evolving on a habitable planet with low enough gravity to make access to space possible using chemical propulsion, in the same solar system as a much smaller planet with all the same resources plus a thin atmosphere plus tiny moons that orbits right on the border of a huge asteroid belt? We're definitely living inside an ultra rare special edition holographic star system, guys. We need to take advantage of the fact that we can A; even get to space, and B; have actual destinations within reach in space, because we're probably the only intelligent life to EVER have this level of luck.
>>11764309Against a the forces of a planet, that would get attritted to nothing, even if it won its battles. World War II featured tens of millions of personnel on both sides, and tens of millions more on the home front supporting them. Both sides were helped by already owning substantial chunks of the planet.
>>11765024Admitting that it's better to start from the moon than doing it from Earth is just capitulating on the original point: Martian/Lunar colonization before mass orbital habitation.
>>11765033I didn't say start from anything, you'll barely have a 1000 people on the moon. People will be LIVING on cylinders, not a shitty trampoline planetoid that atrophies your muscles, same with Mars. All of this guy's>>11765026groundwork will be almost entirely automated, by the way. That's not colonization, orbhabs are the only marketable PERMANENT living space in...Space.
>>11765048Good luck making a fucking O'neill cylinder with 1,000 people and some garbage robots, lmao. You're talking about the largest scale undertaking in human history.
>>11764835They either do not, or they do something called a 'weak capture' whereby an object happens to pass at a very low velocity through one of the Lagrange points between that main object and the Sun, which can cause the new object to remain orbiting the main object for a while, but almost always these objects are lost to interplanetary space again because they end up passing through another Lagrange point. The only time a weakly captured object can become strongly captured is if another force beyond simple gravitational attraction has time to act on the weakly captured object before it can orbit through another Lagrange point and escape. This is technically possible through tidal force interactions, but the parent object in this case must have a highly asymmetric gravitational field and must be rotating relatively rapidly in order to produce enough tidal drag to make this possible in the small time before the new object is lost. Tiny moons of asteroids are probably gained and lost all the time through this mechanism, since asteroids encounter each other at extremely low velocities all the time as they orbit the Sun, and medium sized asteroids are commonly very stretched out and potato shaped while having short rotation periods. These small asteroid moons, once strongly captured, either migrate into stable orbits aroudn their parent asteroid, or eventually have their orbits decay until they collide at low speeds and collapse into a single asteroid. It seems likely that a great many rubble pile asteroids were formed through this mechanism.
>>11765058>Garbage robotsIf automated mining/manufacturing technologies aren't on par with making at least one o'neill cylinder a year then we have no business being in space beyond exploration and research. Like what star wars fantasy are you living in to believe that we're going to have millions of people in hardhats out in space setting up space industry?
>>11765071>If automated mining/manufacturing technologies aren't on par with making at least one o'neill cylinder a year then we have no business being in space beyond exploration and research. First it was that we should just go straight there with no intermediate step, then it was "well we'll just colonize a little", now it's stamping your feet and throwing a tantrum if you don't get an O'neill cylinder per year. This fantasy is degenerating quickly and contains no trace of a sense of scale.
>>11764989the main advantage of o'neill cylinders is that you can have pretty much optimal conditions for human life, for a lot of humans. The main issue isnt economics or technology, it's demographics. You just aren't gonna have enough people to warrant more than a few dozen to hundred o'neill cylinders for a long, long time yet.
>>11765080>straight there with no immediate stepWhat was I referring to here? I was referring to living in space, that's what all of us were talking about. Are you implying that I was implying that we build an O'Neill cylinder from scratch using material from Earth? That's a strawman, we were talking about permanent settlement.>you don't get an o'neill cylinder per yearSeriously what the fuck do you think an o'neill cylinder is, because you make it sound like it's the equivalent of constructing a ringworld or something. An O'Neill cylinder barely counts as a "megastructure", a space elevator/orbital ring on Mars is a bigger undertaking, which I'm sure you have no problem with constructing. Talk about sense of scale, you don't even understand what I'm talking about.
>>11765109How does this problem of demographics compare to colonizing the Moon or Mars for permanent settlement? So far all of the arguments levied against orbhabs have been economical or technological problems so I'm genuinely interested.
>>11764951While I don't think they'll make this deadline, I'm getting increasingly worried that they're cutting a lot of corners on Starship's safety to meet this goal. 2024 cargo and 2026 crew would still be a bold and immediate target with less silliness.
>>11765115>Are you implying that I was implying that we build an O'Neill cylinder from scratch using material from Earth? You sure as shit aren't building one anywhere that lacks a strong construction-oriented infrastructure already, which you aren't going to get without significant colonization. >. An O'Neill cylinder barely counts as a "megastructure"You keep thinking that while you figure out how to get hundreds of millions of tons of shielding and structure into orbit and constructing something useful out of it with ~1,000 people and some robots.
>>11765132It's very clear that Musk has no problem pushing back a deadline if something isn't good enough. There's nothing wrong with having ambitious timelines as long as you aren't so shamed by the failure to meet them that you push something out before it's ready. Musk has no such shame.
>>11765132>>11765146the cargo target is within plausiblethe manned mission will slip for sure
>>11764836Nuclear power is the cleanest form of energy production, and no society running off of energy that cheap would bother with landfills, because it would be cheaper to power the processes that are required to strip waste products down to simple elements or chemicals for complete recycling than it would be to mine more, 'fresh' material and extract those same substances from the rocks. Not to say we wouldn't still do the latter, we'd just have no reason not to do the former.Space industry will help 'fix' Earth by providing new technologies and a huge amount of excess industrial capacity with zero additional impact placed o Earth's environment. It won't be the case of "all our dirty shit happens in space", it'll be a case of "we really don't have any 'dirty' processes anymore because it doesn't make any sense not to take all our waste materials and reuse them". Even shit like fission products from breeder reactors will be highly valuable, because if you just alloy those isotopes with iron and cast that hot iron slug inside a stainless steel capsule, you now have a source of heat that stays hot for a decade with no input power and lets you melt water ice for extraction basically for free.
>>11765143>You sure as shit aren't building one anywhere that lacks a strong construction-oriented infrastructure already, which you aren't going to get without significant colonization. Significant colonization is what, exactly?>You keep thinking that while you figure out how to get hundreds of millions of tons of shielding and structure into orbitWhat orbit? Are you still talking about Earth?>and constructing something useful out of it with ~1,000 people and some robots.Love the way you downplay that shit. Like what is the alternative? I jokingly implied earlier that you expect millions of people in hardhats to be working on infrastructure in space, but I'm starting to believe you actually believe that. Are you arguing that robots aren't a lot more efficient than people at building anything, especially orbital infrastructure? That's my argument literally what is the alternative?
>>11764309The allied powers had 70 million troops in WWII and they only had to fight in 2 theaters. 70 million to overcome just the axis powers and you only want to send 2 army groups to neutralize an entire plant? You are retarded.
>>11765048>groundwork will be almost entirely automated, by the wayScience fiction.
>>11765174>Are you arguing that robots aren't a lot more efficient than peopleAnyone who argues that robots are better at anything more complicated than stamping sheet metal parts is a retard
>>11765122Think of what an O'Neill cylinder is: a massive fuck off megastructure. Sure, it's probably a more desirable place to live than on a planetary surface (other than maybe Earth), but why would one get built when you've got a population of maybe 5 million on the Moon or Mars, and no bottleneck in sight other than the minute natural population growth?The people who could go about constructing something as major as an O'Neill cylinder, could spend the same amount of money on creating something much, much more desirable to live in on Earth, because frankly, when you look at population trends, it's pretty clear that overcrowding isn't going to happen or become a major issue, unless something major changes.Of course, its perfectly possible that a couple get manufactured as presige projects or w/e, but I really cannot see the demand for many of them (to the point that they become a place the majority of people live) for a long, long time yet.
>>11765185seriously, where do people get the idea that these autonomous building robots exist or are close to existing? Have they ever seen anything on any construction site ever that is even remotely autonomous? Even factories have a hard time integrating AI for trivial, single-purpose, stationary robots.
Even if Starship doesn’t fly until 2030 - which is unlikely given how fast they’re going - it’ll still dominate the aerospace industry within a year of its first flight.Have faith brosBut holy shit if it flies before SLS NASA will commit suicide on live tv
>>11764900Excuse me? It would literally be cheaper to land on the Moon/Mars and build an O’Neill cylinder on the surface to simulate earth gravity using in situ resources vs. launching stuff into space to build it in orbit
>>11765196Agreed. Source, I worked for 4 years in a factory that was supposedly 90% automated. Literally every fucking day we were running around unclogging shit, fixing shit, replacing fuses, replacing motors, replacing valves, replacing belts. The idea that automation is almost ready to take over all manufacturing is such a joke it isn't even funny. Grease monkeys lubing machines and running electrical cables will be an essential job forever.

>>11765196ZeroG would make a lot problems robots have a much easier. And a giant ring rig that slowly "prints" a oneill cylinder is the most accept theory on how these would be made. The amount of materials i would need would still be astronomical and would demand a big space industry something that is still decades to a century away at our current rate of advancement.
>>11765248>ZeroG would make a lot problems robots have a much easier.no, because the primary problems are software problems, not robotics problems. We've had robotic arms and tools with enough fidelity to accomplish these things for decades—actually orchestrating them in a robust and useful way is the difficult part.

>>11765258*lands on your village house before falling over and exploding*nothing personnel comrade
>>11765258Whatever happened with pic related?
>>11765238This is a thing people don't often consider. There's no reaosn why you couldn't do rotating habitats on the surface of the Moon, they'd still be cylinders just oriented vertically, and they'd spin to produce a combined total of 1g apparent gravity, at an angle that would make you feel like your city was built on a hill. You can't do dish shaped like some people suggest, because you'd have significantly less gravity at the inside rim compared to the outside, and it would be at a different angle too. The weaker the surface gravity of the object you're building your habitat on, the smaller the apparent 'slope' you'd feel on the interior surface. Mars gravity is probably too strong to do this, but Moon gravity should be alright, and the gravity on anything Triton sized or smaller is definitely weak enough to deal with.Ceres would be a good place to cover with rotating habitats to a depth of a few dozen kilometers, in fact you could use Ceres' surface as a habitat factory and lift them into space using a steel cable space elevator 900 km long, and release them on a Ceres escape trajectory so that they orbit the sun and can maneuver close to other, smaller asteroids to mine them as well. Once we have big enough rotating space habitats that each one can house the labor force and industry necessary to build more habitats, the colonization of the solar system by mankind would appear analogous to bacteria colonizing an agar plate, ie exponential growth. There wouldn't even really be anything stopping us from doing interstellar colonization at that point either, just send ten thousand habitats on a 1000 year trajectory in a big cloud and have everyone pack a lunch. If 1000 habitats break down every decade, all you need is the other 9000 habitats to disassemble those broken down ones and use their materials to build fresh new habitats.
>>11765248>ZeroG would make a lot problems robots have a much easier.Metallic dust getting into the electronics gets worse in zero G. Software drivers aren't affected by zero G. Lack of convection makes thermal management worse in zero G. Objects floating and spinning in zero G are much harder for software to recognize and for robot arms to grab than stationary objects laying on a surface. Robotics are already far stronger than necessary to comfortably handle heavy objects in gravity, zero G is not a benefit in this aspect. Zero g means bubbles in hydraulic fluids do not rise to bleed points and instead pass through pumps and into actuators. Etc etc. Zero G is a nightmare design environment for automation.

>>11765265>You can't do dish shapedi mean, you can, so long as the radius is quite a bit larger than the actual height of the cyclinder/bowl, so it'd be more of a circular section of a bowl rather than the whole thing. Even then, having sections of differing gravity could be a good thing, for anything from housing the elderly, heavy industry, recreation, or acclimatization.

If kessler syndrome happened couldn't it be cleaned up with high density magnetic cannon balls shot en masse through orbit? It would take awhile but be relatively low cost.
>>11765379would nukes work as well i wonder?
>>11765391Nukes fuck up the atmosphere way too much. If you just have a super heavy cannon ball do a few orbits before flying off into deep space that would be pretty effective at cleaning debris. Most debris would also eventually settle on a similar plane making it easy to target.

Kind of an odd question but do y’all think part of the Artemis objectives should be to send astronauts to the lunar surface to construct like, say a kilometer of perfectly flat and level land to help future missions? A sort of landing area? Obviously the first missions will have to go Apollo-style and search for flag land, but wouldn’t it be advantageous to create an area dedicated to safe landing? I mean they’re already sending geologists up there so they could check the structural integrity of the modified regolith and streamline future landings
>>11765407Prob Starlink. Alphabet/Google/Sergey are big into SpaceX/Elon
>>11765425No anon, that would mean the flights were actually doing something and that would be too cost effective.
>The satellites are working. We've got a launcher which is mostly reusable. 80% reusable. Our marginal cost of launch is much lower than it's been ever in the past. A million dollars a turn. That's really pretty low. brainlet here, could someone explain how marginal launch cost is different from regular cost?
>>11765439Marginal cost is the cost of launching one more time after developing all of the rocketry and manufacturing process and getting past the red tape. Fixed cost would be all of that money that needed to be spent before one launch happened.

>>11765685Yeah I’d rather names be chosen after famous scientists like Braun or Wegener. Although naming after legacy ships is cool. I hate the name Endeavour, but Challenger was named after the HMS Challenger (the first oceanographic mission to chart the ocean floor)

>>11765716He could also name the first three cargo ships to Mars the Nina, the Pinta, and the Santa Maria after Columbus's ships.
>>11765720the optics on that would be awful
>>11765722They'd be the first ships to a New World. It's an appropriate metaphor. There are no indigenous Martians.

>>11765722fuck your optics, we're going in
>>11765727You don't know that you fucking bigot. They could be invisible or underground.
>>11765727it's not really, Columbus was trying to go to India, not settle the new world. The Puritans were actively trying to find a new life.

>>11765563No individual ships, stations, habits etc should be named after real people. Programs named after mythology are better because it is an ideal and a lofty one at that. The only issue i have is they aways use roman or greek deities, i want to see a woden information gathering rover network, A Belenus sun orbiting probe program, a Tyranis weather satellite system, a Wayland base building Program, a perun gas giant weather orbiter program and Hermod Mars-Earth communication program. The only reason we don't like mythology recently is because they lazily did artemis because muh Apollo's sister muh womyn bullshit.

>>11766041they need to close the roads to move it, then test it, then static fireone of the tests should be an hour long (I didn't look at the picture)
>>11766035June 8 will probably be a farm and equipment test with SN5 being moved into position on June 10th. That or they are only giving an hour to move SN5 then a cryo 2 days later, which could be possible but it is thought that they did cancel the planned test last week.

>>11766040>If Starship launches before New Glenn there's really not any point to New Glenn.This. If Starship is going to obsolete a workhorse like F9 (and it will, although I think the tail will be longer than anticipated because oldspace contractors hate change), new unproven partially reusable vehicles are dead in the water. At least other projects like with ESA and China have the "practically obsolete but national interest demands it" thing going for them, BO relies entirely on grabbing contracts from salty Starlink competitors that won't launch with SpaceX, which is a suicidal market that doesn't have long term solvency.
>>117660442 posters started on it, i stopped it before they went further

>>11766070And was the biggest chunk of NG's manifest, but iirc every other contract has been with prospective constellations as well. At least OneWeb may be saved by SpaceForce, I guess.
>>11766063you didn't do shit
>>11766038No
>>11766076So they're going to try to win it by what? Branding? Starlink will have 1000 satellites deployed before blue orgin has a rocket.
did anybody else go stargazing last night to see the clumped-up Starlink pass?
>>11765428Yes, Starlink is the only one exists and google is largest SpaceX's stock holder after Elon.
>>11765997oh shit is that the improbability drive craft?
>>11766083>At least OneWeb may be saved by SpaceForceDidn't the military already sign a contract for starlink?
>>11766087>So they're going to try to win it by what? Branding?Bootstrapping internal use. Every Amazon office building and fulfillment center needs a reasonably fast connection to Amazon's datacenters, which limits where they can be located. Switching to Kuiper keeps it all in-house and allows any two-bit flyspeck town with an airport large enough for cargo planes to have a fulfillment center. This massively expands Amazon's potential for same day delivery, and so Amazon will be buying lots of launches.
>>11766087Price maybe? or Bandwidth?We have to wait anon, if there's going to be competition for fast internet in far off areas there's going to be more money poured into space
>>117660471hr closure on 8th (beach remains open) prolly for the move, 10-12th >>11766041
>>11766093Yes, but they would rather have a redundant network and simultaneously avoid OneWeb going to China.
>>11765992What does reddit have to do with sikhs you absolute fucking mongoloid
>>11766095That would make sense, so its still going to happen then. I just can't imagine them competitive with starlink but if they have the network and integration then they may be able to compete

>>11766146it's all for AWS which is where Amazon makes most of their money.

>>11766190We already sell direct fiber connections to AWS datacenters through partner companies, that'd be faster than any satellite. I'm pretty sure the big push is for getting retail FCs and devices into more hands in rural areas and the third world.t. AWS dev
>>11766196>that'd be faster than any satellitethis is for starlink, but it applies to any constellation:https://www.youtube.com/watch?v=m05abdGSOxYit's even faster if they actually figure out the satellite-to-satellite laser link
>>11766196>We already sell direct fiber connections to AWS datacenters through partner companies, that'd be faster than any satellite.Light moves slower through fiber than vaccuum. That speed advantage is one of the big prospective opportunities for Starlink (high frequency trading) but it'll have to wait for the inter-sat laser uplink to take advantage of it.

>>11766353I have never been interested in Artemis because the concept of intermediary stations as a bottleneck to the surface makes no sense. Lunar development interests me but it can't rely on Artemis because the project is too conceptually broken.

Letting those frogs die up there once food air or water runs out would be bad optics, but making the satellite recoverable would be a challenge.
