>space flight

Sounds like you believe in the meme that rockets work in space. Sorry OP for shattering your fantasy world, but it needs to be done.

When you use logic, reason and actual real science, you realize rockets only work (definition: propel themselves forward) inside an atmosphere. This means they don't work in space.

They can't work in a real vacuum. Any claims of the contrary is a fraud and a lie.

>inb4 you parrot "newtons 3rd law!" like an NPC without any thought involved

That law /isn't/ in dispute here. Appealing to it to "prove" rockets "work in space" shows you don't grasp the fundamental problem here. The 3rd law is 100% correct. When asteroids floating in the vacuum of space crashes into each other, the 3rd law applies. Likewise, the law applies to objects interacting on the ground on Earth, underwater, and in the sky. The 3rd law is 100% real, but it doesn't "do" anything for a rocket when its engine is fired in a perfect vacuum.

You see, the atmosphere gets thinner at higher elevation until it disappears completely (out in space). That's the issue here! And you can't get around that issue. Parroting "newtons's 3rd law!" or throwing math equations around, doesn't magically make the issue go away. That's just you avoiding to deal with reality. Man up and stop avoiding reality.

If you're currently under the "rockets work in space! xd!" spell they cast on you through the entertainment industry and educational system (the indoctrination system), and you want to break free from that spell and shatter the illusion - then see these two educational videos (they play inside your browser):

1st vid: https://files.catbox.moe/dl9ldw.webm
2nd (also important): https://files.catbox.moe/so2rrt.mp4

Once you know that stuff, then you know beyond any doubt rocket technology will never be viable outside of Earth.

No atmospheric pressure, zero atmospheric density = no thrust. It truly is that simple.

Perform an experiment to test your claim if you really believe you are being logical.
Test a rocket motor on some fishing line inside a vacuum chamber so it will not push on any wall
If your claim is correct, then when the motor fires, the rocket will not move
If not, the rocket will move around and thus your idea is incorrect and you'll stop spamming this shit, kikemoot

I would tend to agree so long as the normal 3D printing teething problems can be ironed out. For example the relatively recent test demonstration where the two hab teams printed out 1/3rd scale replicas of their designs, both teams had some issues with the applicator heads of their printers hanging a bit causing slumps in the prints. For the team using cement it was probably because cement takes a good long while to fully set and the sheer weight probably played a role, while for the (i'll call it polycrete) structure the issue was with excessive heat building up in the applicator leading to a solution being too runny. This will be exacerbated on Mars or Luna, where heat will have to be carefully regulated to keep the print at a controlled consistency, while a cooling system will also have to reject enough of that heat to keep the print from becoming melty and preventing potential damage to the applicator itself.
Of the two the AI Spacefactory hab was obviously superior due to the much smaller amount of material required and the much more robust design.
>>11776859
I don't understand the fixation with swarms of small robots, that seems like an excessive pain in the ass when one large tracked/wheeled platform with large preloaded tanks of materials and an extendable tool arm could perform the same task. Small vehicles haven't exactly had the best track record of being able to do lots of heavy lifting work in space, I don't understand why anyone would continue to insist on them once Starship comes into play. With a 100-150 tons-to-anywhere heavy lift vehicle there is no need to avoid larger, more robust construction vehicles.

That is why the winner came out on top, their composite material was stronger and didn't clog the head like the other teams cement. NASA is putting a lot of R&D into the building material and printing of lunar and martian regolith. Look at their swamp works program.

Maybe in 2004, NASA is putting a lot of effort into regolith building. Building the houses "normally" on mars and on the moon is going to be much harder than here on earth. Its not a fad, 3d printing is just the easiest way to use the material you have. You don't make wooden houses in the desert and you don't dig for marble in a forest. Its legitimate and NASA is putting a lot of resources into the concept, that competition was just to float some ideas and test them.

I've been a big space nut since I was a kid, and seeing new things being built and launched was always fun and exciting, but even before the spaceflight drought really sank in there was always a hint of disappointment with these projects too… its was like, "Ok, that's great, but when are we actually going to *do* things?" It was all about rinkydink LEO toys and rad-hardened RC cars, with the highlights being probes like Cassini.

Watching the ITS announcement had me probably the most excited I've been in the decade before and the years since. I almost didn't care if it all ended up being bullshit, because finally someone was presenting plans for a real fucking spacecraft.

This looks very sleek and practical, except for the large openings that leave the interior open to dust storms. AI Space factory design looks very nice but they haven't said anything about how they'd make the interior, did they? I guess it could be prefab on earth and assembled on Mars, and only the outer shell would be printed.
Those designs make me regret not continuing the Mars project I did in architecture uni. My buddy and I did a course where we used robots to 3d print a supersaturated natrium acetate solution that would turn solid really quick as soon as it touched anything. We made a script so we had an interactive 3d printer, telling the robot where to drop the liquid. Because it hardened pretty much instantly, we could build really cool structures and even 3d print horizontal without any support.
Anyway, the last step of the project was to come up with an architectural application. The structures we made had an extremely fine and detailed surface, so we imagined them to be huge megastructures scaled down. And where do you put something like that? On Mars, obviously. So basically our idea was similar to AI Space factory, only instead of small homes, we envisioned gigantic autonomous factories and 3d printers creating these massive, interconnected towers out of molten Mars rock. They were up to 3km tall and around 200 meters wide, with a 30-50m exterior wall to protect from radiation, meteors and storms. The idea was to build them autonomously and make them pressurized, then grow plants inside. Because they were so huge and interconnected, after a few decades they would have a self sustained atmosphere. Then the humans would arrive and live inside those huge cave towers. Think of it either as giant scale 3d printing or small scale terraforming. We figured why not terraform a self contained small area rather than the whole planet..
We didn't follow up with the project because his wife died unexpectedly and we kinda lost contact after that.

Maybe docking clamps like they have in the Expanse? There's that scene in season 1 where a small shuttle is docking at a capital ship. The capital ship basically reaches out with a huge arm, clamps onto the shuttle and pulls it in.
So maybe we could do a low tech version of that with some kind of tether or hook that catches the shuttle, kinda like jets landing on an airplane carrier. So instead of docking directly, the shuttle has to catch the hook and is then reeled in. Idk. Space fishing.

He inherited a somewhat bloated organization focused on keeping itself alive while trying not to get everything cancelled with regard to deep space human spaceflight. He has the job of pleasing POTUS, and I think he has become tired of oldspace’s “business as usual, makin’ money” way of functioning.

unfortunately, the procedure to build this would be different from the way we built the model. Here, we had an IV drip hooked up to a robot, dripping the solution onto the model. The "real" structure would be more like FDM 3D printing, like the AI space factory people. Only that our printheads would be 50 meters across and extrude molten rock and metal.

I thought about writing a sci-fi story in this setting, but now I think you should do it. We really do need more Mars games tho. Surviving Mars is comfy but it feels way too easy.

Would it be feasible tho? To have automated mining rigs digging up the surface of Mars, delivering it to a massive factory where the material is converted into a filament of molten rock and metal that is then send through pipelines to the massive extruders. The extruders would be this rotating platform with 3 or more arms extending outward. At their end would be the actual extruders, receiving their material through the pipeline coming up in the center of the platform. The entire thing would sort of ride up on the part of the structure that's already printed. Kinda like a crane that is riding up the skyscraper it's constructing. And because it's simply rotating, you don't even need to plan or slice anything. Just turn the thing on, feed it with material and it will grow this massive tube of rock.. I think I should pick up this project again.

Mars gets a lot of meteors tho. Look at this pic, there are thousands of impact sites everywhere. How would a glass dome deal with this? I guess it could be build out of relatively small triangles and need some trusses in front of the glass for protection.
Then there are the issues of dust and temperature differences between the exterior and the interior of such a dome. Because of the dust, it would be dirty as fuck really fast. How will it be cleaned? Will you waste water on Mars to clean your windows? If you want a comfortable temperature, you will need at least 18°C inside. 20-22°C would be better. What happens if you get a cold night of -120°C outside? Those windows would be fogged up as FUCK.

How many cars can a space elevator even support at one time? How much could such a car carry? How fast would it move?
Even if we had some ethereal material that could do it on earth and even if we put the trillions in to make a cable long enough to burry a city or two under it, it would still just be a small thread initially. How much could you possibly move using such a flimsy thing as infrastructure?
Also the premise of an elevator in one fixed location governed by one state would open anything up for anyone seems like wishful thinking.

Stars rotate, and as they collapse into black holes this speeds up their spinning, kinda like how when you're on those spinning things at kid's parks, if you move towards the center it spins faster. Apparently they do this because black holes sometimes aren't points (singularities) but rings (ringularities), which lets them spin despite missing a dimension.

There is a rather high chance that you are sitting on a rotating chair. Go to the freest place in your room, form a sitting T-pose, and spin on you chair. If you then draw you arms inwards, you will begin spinning faster. This is because of the conservation of angular momentum, the less your radius is, the faster you go. When a star, typically a red giant, collapses into a black hole or a neutron star, its radius goes from from several AU to several kilometers, which causes insane rotation (several turns per second).

Google said that the surface of lava takes around 15 mins to be cool enough to walk on, but the interior can take months to cool down. So let's give it an hour per layer until it's hard enough for the next layer. A lava flow is typically about 1-3 meters thick, so that would be our layer thickness. The inner radius of the tower is 100 meters, so it's circumference is roughly 785 meters at the center of the wall.
If we aim for 1 layer or meter per hour, the extruder would need to travel at roughly 0.2 meters per second to make 1 turn in 1 hour. But since we have 3 extruders, it could go 3 times slower, so 6-7 cm per second. Does that seem reasonable?
It would only take 1k hours to create a 1km high tower, or roughly 42 days.
Even if we only make 1 meter per day it would take only a couple of years.

I guess 1 meter is a fuckhuge layer when it comes to 3d printing and having a 50m wide extruder seems pretty big. So maybe the layer thickness can be smaller and the extruder would be made up of many small ones, which would mean faster cooling of the structure and possibly higher print speed.
So where do we get 40 million cubic meters of lava?

Always worth considering that Mars has only a bit more than a third of Earth's gravity, any structure you build on Mars can be either thrice as tall or thrice as thin without being structurally compromised. On Earth wind speed and swaying would also be a concern but while wind speeds on Mars can be high the air is so much thinner that you'll likely never encounter a wind on Mars comparable to anything more than a stiff breeze on Earth.
Erosion would be your primary concern in regards to wind but if you make your structure from some kind of basalt/plastic like the AISpacefactory team and it's several meters thick you would probably be looking at tens of thousands of years of structural lifetime before you'd have to worry about it.

The other unique aspect of additive manufacture that's at least very difficult to achieve with normal construction is that 3D printers can create complex single piece load bearing elements, so for a Martian megatower it doesn't necessarily have to be built super thicc just to hold up it's own enormous weight, you can have computers figure out where you could leave hollow spaces or honeycomb structures to greatly reduce the volume of material consumed.

Would you still have to worry about altitude sickness from going to the bottom to the top? On earth, there's a significant difference in air pressure, but on Mars the entire thing would act as one big pressure vessel. Would the air still sink towards the bottom and thin out at the top?

That does make sense when you reach the city sized scale, I think the reason we're mostly seeing individual habs right now is because that's about as ambitious as a single launch allows for. Personally if I had the funding and the particular interest, I'd design a set of habitats of varying sizes from say a minimal 5-person hab to a huge 50-person complex.
I'd have all of the structures partially buried, say enough to have the first story of any building be a basement. You can reuse that material later for extra bulk or shielding, then the sections are planned out ahead of time and you excavate a pattern from the center out. While the excavator digs the impression of your colony into the ground the printer will follow behind it and lay down the structure.
The process would start with whatever the largest buildings in the plan are and generally move out in a spiral so that the machines never get in each-other's way. You'd stop before the spiral turns into a complete circle of buildings so if expansion is needed you could simply draw out a slightly longer tunnel and start a new set of complexes.
Granted, at some point there will be more chaotic expansion, but I'd wager that will take some time, and by the time you have that many humans on Mars you won't need to rely so heavily on highly self-contained construction processes.

Concrete-like substances (ie anything that is mixed, poured, and cured at low temps in large volumes) can work on Mars, but you need to place a pressurized tent over the construction project in order to stay above the vapor pressure of whatever liquids are in your mix. For normal concrete this is only ~0.017 bar for water at 15 degrees C, so you don't need to go crazy with the tent material strength or wall thickness.

Hot atmosphere balloons would still work on gas giants, depending on the strength of your balloon materials you may need to go much hotter than an earth-based hot air balloon though. A simple atmosphere-cooled nuclear reactor would be able to provide gasses at over 1000 degrees pretty easily.

Slow to accelerate but much more delta V for a given propellant mass (given the same mass of propellant and the same level of thrust, a chemical thruster would run out of propellant between 10x and 100x faster than the ion drive).

IIRC the mold is just the blade at the bottom, a reservoir at the top, and a spiral channel connecting the two, and the tricky part is to control the rate of cooling so that it solidifies from top to bottom, with the spiral channel down selecting to a single crystal grain by the time the solid front reached the blade section of the mold.

if SpaceX has the capability to send people to Mars, NASA's gonna be one of the first to buy it. Hell they'll probably buy transport for a whole goddamn Mars base. Now notice how SpaceX doesn't really have much of a plan for actually living and doing stuff on the surface of Mars? Well NASA can help with that, and in fact if SpaceX asks they may be required to. One of the big roles NASA and other government agencies have is working on tech considered too crazy for private industry to work on, so they can eventually hand it off to private industry. SpaceX doesn't really do much science either, so NASA can do that. They could send probes to every body in the solar system, build huge telescopes, and maybe even send people to parts of the solar system Elon would be scared of.

Not outright laying the plan out publically != no plan.

Likely the only reason they haven't given a full project layout is that it's so subject to change as Starship and everything else matures.

VIPER is very much not a shitty rover. Do you not realize that VIPER is an ISRU mission? The entire VIPER mission is about learning more about water ice on the Moon so that we can mine it. This is directly relevant to humanity's future in space. The water mined might be used for PROPELLANT, propellant, refining metals, for humans to drink, and PROPELLANT. Mining water could even be profitable to support space tourism or reboost communication satellites. But right now if you tell investors you want to mine water on the Moon, you'll be laughed out of the room. We know there's water ice on the Moon, but we don't know exactly what form it's in. It could be underground, could be a thin frost on rocks, or just some chunks of ice distributed through a crater. Neither do we know what impurities that water ice has. We need to know all this so we can practically and profitably mine it. Sure you could just starship an excavator to the moon, but if you find that really the ice is just a thin layer of frost, well you won't be able to mine significant amounts of water. But if you knew beforehand, you could have sent up something that hoovers up that thin layer of frost, rather than having to beg your investors for more money.

But its okay to be drunk on SpaceX's success, because it's driving massive interest in space for NASA's goals and honestly for the org itself. Boeing basically is a basic bitch that can't deliver. Blue Origin has been rewarded money for a lander drafting plan with a few other companies in a joint venture, but those fuckers haven't launched a single fucking rocket to orbit yet. Sure they've built payloads and their launch facility is being stood up, and they've made progress on an autonomous ship that can pick up the rocket at sea post landing. Which is fine, but compared to SpaceX's cadence, it doesn't feel like BO is an exciting company worth pursuing interest in.

That leaves Rocket Lab, who do cool stuff, but they're very small sat market and are all LEO products. There's also Relativity Space, which is also doing something really cool, but scalability and roadmap to large, crew capable rockets or major payload deployments off world is probably a decade or more away with them--and they have a 50% chance of folding or being acquired by someone else within that period.

Given all these factors, the only REAL game in town becomes SpaceX. So it's in his best interests to promote the values, models, and initiatives of SpaceX as best as possible without wanking favoritism as NASA did with Boeing and old space.

So we get that part, but it still doesn't understand the glass question. Earth has sand, silicates more specifically. Does that exist at scale on Mars? I know that we know that Mars had a huge fucking ocean a billion years ago. So the plausibility of sand being present is probable. But it's been a billion years or more, so the probability of that sand being gone is equally probable?

of course Mars has sand

You can dredge silicates right out of the regolith just fine. It's all over the place.

O'Neil Cylinders or Habitable Ring Stations will need carbon nanotech production capabilities at massive scales. It's the only material that has the flexibility, tensile strength, and long-term durability, in addition to it's other "magical" properties to allow for construction of these structures.

Also, we're going to need to have asteroid mining, refining and production of material goods also at an equivalent scale to facilitate this. Mostly due to needing water, nitrogen, phosphorous, a whole fuckton of rock/soil, and oxygen--which exists in abundance in the asteroid belt and other planetary bodies within Sol.

O'neill cylinders were conceived with steel in mind.
Asteroid mining is highly unnecessary. Mars all of that in abundance, and the Moon can contribute a fair amount as well.

I believe they do 60 in order to have the margins to land the booster as well as have enough fuel in the 2nd stage to get to the staging orbit for the sats, while ultimately allowing the 2nd stage to also, in time, burn up in earth atmosphere to not pollute space.

The thing with O'Neil Cylinders though, is that you need large transparent surfaces. CNTs have transparency capabilities I believe, and if not, they can serve as MASSIVE screens, which can basically project the outside space in.

You don't need that, and it's actually fairly terrible as you give up so much livable surface area. Pumped light works better.

>The question is how do you provide 1g to the womb
A gainstation is not like the ISS, a gainstaton is a rotating habitat where the interior environment is at 1g or above. Impregnated women would be shipped there to live for the ten months it takes the baby to develop in the womb at a minimum, but it's also possible that they'd stay for several years into the child's development period to avoid complications. This is only based on the idea that the minimum amount of G necessary to develop a human baby is close to 1, which may very well not be the case. .

Dude shit the fuck up, the op had a design for an extruder head 50 meters wide that laid down a one meter thick layer of print material per pass. It's obviously beyond the realm of practicality and even feasibility.

>Now certainly there should be designs for the habitats,
Initial habitation provided by Starship crew cabin, ~1000 cubic meters total spread among probably no more than ten people per Starship. Additional habitation constructed in-situ out of aluminum sheets (shipped as rolls of metal) using simple bending jigs, hydraulic shears, and electron beam welders (total equipment mass no more than ten tons pessimistically, meaning a single Starship could ship all the equipment plus ~10,370 square meters of 5 mm thick aluminum, which would be enough to let you construct (very rough estimate) 20 habitat cylinders with domed end caps containing ~750 cubic meters of pressurized volume each.

There is really no reason to go more complicated than simple capped cylinders as your habitat's outer mould line. All those shitty architectural mock up designs can wait until we have some actual useful living space installed. It's not like people are going to be taking strolls outside often enough to get depressed looking at their stack of cans. Furnishing the insides of the habitats is much more important and offers more freedom away from needing to consider pressure differentials anyway.

As for life support for the habitats, guaranteed they will take all the same bits of equipment used for Starships life support, stack them into a box beam frame, and mass produce them as modular units that you drag inside and plug into the grid, effectively the same as installing a hot water tank or a furnace in a home on Earth. Each module would have a rated carrying capacity, and the habitat itself would have enough of them to offer a decent margin in case one module needed to be taken offline.
>mining equipment,
Buy frames and hydraulics from existing suppliers, add battery packs, add insulation and heaters, add remote control and pressurized electronics box, add thermal inertia and radiator, done.

>propellant plant,
They've probably got 6 different designs on whiteboards and in CAD files being developed in parallel for different surface conditions and with different assumptions made.
>greenhouses
Gay shit. For the same mass of a greenhouse (with windows etc) you can bury a pressurized aluminum can in the side of a hill, roll out solar panels, and string up red-blue LEDs, and get greater productivity with far less engineering effort. In fact, since it would be so much easier, it would probably make more sense to do the LEDs in a can option even if they had the same performance. They won't grow any significant amount of their own food in the first 6 years of living on Mars anyway, there will be a low enough population and bigger problems to deal with so they'll just eat what gets sent from Earth, apart from herbs and greens grown in-situ as supplementary diet options so they don't slit their wrists or whatever.
