Seriously though I doubt nuclear bombs would be developed until the mid/late twenties due both to lack of necessity and lack of capability compared to what the US had during WWII. Even then there was a lot of collaboration with the British and it still took four years.
Also I'm pretty sure Hitler only started calling nuclear physics jewish after they actually went to war with America since he knew they wouldn't be able to catch up in that field so he just took the opportunity to cut his losses and demonize the enemy more.

You'd be best off if you caught Hitler before he had a chance to form an opinion, and told him that the jews were going to recognize the power of nuclear energy and do everything they could to prevent others from developing it, including subterfuge and reverse psychology tactics. Convince him that the reason he believed nuclear was a jew science was because that's what the jews wanted him to think, in order to hamstring himself.

A rotating space colony can have any gravity it want, any biome it want.
You can have a Desert and high mountain one colony away. And linking colony together is nowhere difficult.
Living in an underground biome on mars force you to have Mars like gravity.
You only gain with the hypothetical size of the dome.

No one is going to enforce where you live, but living in space colony will be cheaper and more accessible at first than turning Mars into a factory capable of churning every component needed to live there.

No it's not, it's got the best launch economics per payload mass of any launch vehicle currently operational. The only reason FH was delayed and has not flown often is ironically because the Falcon 9 ate most of its lunch. Originally FH was meant to launch up to like 30 tons to LEO and ~10 tons to GEO, but Falcon 9 ended up improving to the point that it's close to achieving those numbers on its own. Likewise, FH grew to be a monster in the current commercial launch market.
If it weren't for the political shitstorm it would cause, FH could easily serve as the defacto SHLV of a new Moon program. Literally just two launches of Falcon Heavy put up as much payload mass as the Saturn V, and baselining three launches would let you design missions significantly more capable than Apollo, for just ~$400 million per mission.
>it would be hard to manrate
Nah, SLS is harder from a technical standpoint to get to human launch reliability, but NASA pushes the paperwork through. FH isn't getting manrated because it would cost money that SpaceX doesn't want to bother spending.
>but orbital assembly!
Apollo had to do it during every mission, twice. It's not a big deal.

FH is a fucking great rocket which unfortunately doesn't have much to do and is going to be made irrelevant completely by SpaceX's own next gen rocket.

i dont know aboout oneil cilinders, but in long term space colonies, either artificial or hollowed asteroids are superior over mars in my ways

mars:
- 0.4g, potentially fuicks up your body
- radiation, need to hide underground or in shielded habitats
- need to extert fuel to go to orbit
- dust everywhere, fucks up equipment
- there are some mineral resources, ice for water, atmosphere for fue production

asteroids:
- no need to use fuel to go into orbit
- can spin to provide useful 1g gravity
- every possible mineral resource you can think of
- need same radiation shielding as mars.

overally, asteroids can provide much more controlled enviroment.

i am not against going to mars, but my thoughts are about long term fate of space civilization. unless we find earth like panets, asteroids are way to go.

The Orion is overrated and a memetic trap.
It's like propaganda, good and simple in appearance, wrong and complex behind the scenes and you can't get rid of it because simpletons think it's awesome.

This is a drive that cannot afford to fail even once because its failures mode are all horrible.
you simply cannot use it to take off if it fly over anything of importance,
you cannot afford to lose prototypes during take-off and landing one will require minor miracle,
all the complexity you believe to have escaped you'll get it trying to produce and use the finely shaped bombs, like trying to build a watch using only a big hammer.
you cannot use it in any important orbit because its engine will generate debris,
it can hardly be throttled for fine maneuver or used near anything else,
it cannot be built with much redundancy because its starting mass and shape are big,
the only fuel it can use require a long supply chain, so it will be from Earth.

Yes, but it doesn't matter either way. Elon is clearly the one steering the ship and he's doing a fucking amazing job of it. Just compare SpaceX to BO; the latter has effectively infinite budget and is two years older than SpaceX. Has what, 20-ish flights in total? All of them suborbital. Meanwhile SpaceX's own engine tech alone completely BTFOs all other aerospace companies/programs ever, even in history. SpaceX's rockets are the best in the world, not even memeing (they're the cheapest and can hit all the same orbits, ergo they're the best). SpaceX's private program is blowing the absolute fuck out of all of China, a nation of a billion insects, and India, a nation of a billion poos. Current SpaceX black magic engine turbopump hex technology is even more arcane than the Soviet ORSC engines from the 60's and 70's, while being literally orders of magnitude cheaper to build.

>you cannot use it in any important orbit because its engine will generate debris
Not really, if the pusher plate erodes at all it will do so in the form of an ultra thin layer of ablated iron plasma which would rush away at dozens of km/s. The bombs themselves get transmuted into plasma expanding at dozens/hundreds of km/s, which is why the drive is so efficient in the first place. Any and all of the debris produced by using the drive is also inherently moving much faster than escape velocity of both any planets you're orbiting and the Sun itself.
>it can hardly be throttled for fine maneuver or used near anything else,
The Orion drive system has never been proposed as a 100% catch-all propulsion system you'd use for spacecraft. Instead it's sort of like a main cruise engine; it gives you large delta V budgets with a burn impulse resolution accuracy of a few dozen meters per second. Any Orion propelled vehicle would have a secondary propulsion system meant for fine adjustments which would only need to have a total delta V of maybe a single km/s. This system could be chemical rockets or nuclear thermal rockets but in either case it would offer a much more accurate burn-finalization than the Orion drive itself. If you really wanted to only use high Isp solutions though, you're just use a pulsed microfission engine for your fine control, which works basically like an Orion drive except the "bombs" are small pellets of high enriched fission fuel that get crushed by electromagnets and zapped with neutron beams in the thrust chamber, and the engine runs at ~60 Hz and a few kN thrust instead of 1 or 2 Hz and MN thrust.

Still not worth using for take-off which was its only/main selling point (and the main/only way to get it up there at all). You don't want it to be expandable and it can't land.

It can be used more safely in interplanetary space but mostly once you are safely away from important stuff/orbit and the only (early) source of pulse unit will be Earth.
By the time we need interstellar travel we are likely to have found much better design.

There's a big difference between
- Slowly detonating one nuke-pulse with plenty time to fix any problem and recalibrate.
and
- Continuous nuke-pulses or you'll crash with a full load of nuclear bomb.

>>12513377
The system to get it past the pusher plate is far more important and difficult than just making a catapult and a trap door. You don't want it to fail or get stuck in any position you are not aware off or give erroneous feedback. Since it have to be lined up you can hardly just double it.

The nuclear pellets will need to be finely shaped because they are supposed to produce a directional explosion and not leave behind debris. Directional explosion will require the pulse unit to be strong enough to shape the explosion, this is also why other pulse candidate prefer to have unit/pellet explode in a shield that contain the explosion better.

You'll prefer to be able to prevent/fix accidental rotations, correcting the exact positions/attitude because the ship shouldn't have to leave behind unexploded pulse unit.
Just storing nuclear material knowing you want it to be as small and light as possible is complicated.

All nuclear engines have problems and subtlety, but this one have the memetic hazard of making people believe they can throw their problems away and detonate them behind a safe shield in one SSTO package despite being at least equally harder than every other engines.

This would be the major problem, not only were aircraft much more susceptible to the effects of nuclear weaponry but there'd also be no plane large enough to lift one from the ground. Even assuming that the 1910s-20s scientists could solve everything to do with shaped charges and simultaneous ignition at that time, you'd need simultaneous accelerated leaps forward in aircraft engine design to get a plane with enough payload capacity to lift the bomb, which would probably be significantly heavier than the actual Little Boy and Fat Man were.

>The nuclear pellets will need to be finely shaped because they are supposed to produce a directional explosion and not leave behind debris.
It is impossible for a nuclear pulse unit (either a small pellet or an entire self contained warhead) to leave behind debris, because the fission reaction produces enough xray flux to vaporize any material within a radius about 100x greater than the radius of the actual pulse unit itself. That is to say, if you put anything within a one meter sphere surrounding a 1cm diameter fuel pellet, it will be blasted into superheated vapor by the xrays alone. Since the fuel pellet or warhead is deep inside this radius, NOTHING avoids being vaporized. The only way you can produce any debris at all is if your bomb explodes incorrectly and fizzles, ie it doesn't undergo a nuclear explosion. However, even if one in 100 pellets or bombs fizzles, the subsequent nuclear detonations will either vaporize this debris or accelerate it via the same mechanism that the detonations accelerate the spacecraft, except at a much higher rate owing to their lower mass, and this will yeet this debris free of any body they happen to be orbiting apart from the galaxy itself.

Anons, America with nukes in WWI would be doing it the old fashioned way, by having tunnels dug underneath no man's land, dragging the bomb to the end of the tunnel, sealing it, and distributing orders for the men to plug their ears and keep their heads down at 9 am on tuesday when the bomb is scheduled to go off. They used to do this with enormous quantities of chemical explosives too, the capability of being able to accomplish even more destructive power with just one bomb small enough to be carried on a wooden sled by six men would have their generals cackling over scotch and waxing their mustaches feverishly.

By that logic NTR was also a minor technical challenge have have been overcome long ago.
The problem is that Orion have far more fundamental limitation than people believe that make it completely unusable for the job it is best suited at and once in orbit it wouldn't be as practical or efficient as other alternatives.

What it is truly good at is looking awesome for the kind of person who judge over superficial appearance or think government are conspiracy.

Obviously they wouldn't use an implosion design because it's far too technically complex. A gun type bomb is extremely simple and easy to produce in comparison.

Using a plane isn't a requirement either. You could use an airship or balloon to lift the bomb and use the jet stream to drift it toward the general target area.

There's a difference between viable in terms of technology and viable in terms of cost. With an expendable F9 upper stage and a reused crew dragon to carry engineers/supplies you'd probably be looking at minimum $20m in cost for SpaceX, not accounting for the end user cost (or the cost of the booster itself). At that point you may as well just build a new satellite most of the time. If Starship hits its cost goals you can send up a much bigger team with many more supplies (Eva suits, manipulator arms, etc) for <$2m. They could even send up a tanker if needed and fly around repairing a bunch of sats in one go.

How the fuck do you think Orion gets its thrust? Magic? It's designed to take the very short duration, high temperature pulse of plasma/vapor shock front and transfer it into a long stroke length force transfer.
Like I said, if one bomb misfires (fizzles) the next bomb sweeps the debris off into interstellar space. It's not a problem.
You'll also notice that not once did I mention using Orion to launch from Earth, which in my opinion is dumb not because it wouldn't work but because the real advantage of Orion is its massive delta V budget, and its high thrust is just a bonus. Wasting ~9 km/s on climbing out of Earth's gravity well is just not worth it when otherwise you could carry an extra 250 tons of payload to Saturn in 6 months.

If you can't dock it's because you aren't designing your modules with their RCS vectors in the right spots. I recommend launching two tugs with 8 RCS pods total, arranges in 4x symmetry an equal distance above and below the center of mass of your tugs. Launch both tugs at once and after they separate they'll still be really close, and you can screw around with translating and rotating your vehicles and dock a few times for practice. Also I recommend your tugs be pretty beefy, so that they aren't as touchy to control. Also also, caps lock turns on fine RCS control.

As for becoming self-sufficient, what exactly does Mars have to depend on for Earth that it couldn't make by itself, especially keeping in mind the 26 month launch window limitation making all the critical and easy-to-spoil resources a must to produce locally. Computer chips? If packaged correctly, you could fit a million processors on a single Starship probably. Metals are unironically less of a problem for Mars than Earth as on Earth basically all of the easily available deposits are mined out, while Mars is both untouched, and one can always send a Starship into the belt rather than to Earth if one needs something exotic that was spotted in some asteroid. Setting up the initial in-situ production will require a lot of supplies from Earth yes, but it'll be much more economical to send the tools necessary to produce everything locally than to keep sending Starships every 2 years to resupply a colony that will die without said resupply.

>As for becoming self-sufficient, what exactly does Mars have to depend on for Earth that it couldn't make by itself
A molecular omnifactory and the ability to build every single components or space-tech keeping the colony alive.
Being able to mine ore don't mean you'll be able to build component that on Earth come from 20 countries using tools made of obscure material, including organic material from 50 others.
Even if you simply you'll inevitably discovers a lot of things you didn't knew were critical.

I believe the biggest problem will be organic compound and the bioengineering needed to farm anything.

Growing food locally is a necessity for any colony with a population above 1000, as otherwise each supply run would have to bring way too much food. Yes, there may be problems in getting food produced locally, but getting shit to grow isn't as difficult as you think, especially in a controlled environment. At least if you pick your crops right.
As for components, standardization is key. Instead of having 1000 different companies involved in making all sorts of garbage that's put together by 100 other companies, make it 10 companies producing parts and a single company putting it all together. Instead of having 100 different bolts with 100 different screwdrivers needed, enforce a single bolt standard with 3-5 different sizes at most. Instead of each tool/robot using custom made motors, have Tesla come up with 3 different motors in different sizes.
With a 26-month window between resupplies anything organic will be at best halfway past its shelf life before it even gets to Mars. In-situ production of local goods will be prioritized with the total percentage of the supply run it occupies, so if food takes 30% of each supply run + biggest limit to colony growth, that'll be prioritized to be produced locally. Motors for everything moving on mars take up 10% of the supply run space? Produce as much of them as possible locally, in terms of parts at least. You may not be able to produce a motor locally for 50 years in full, but producing the most heavy/spacious 80% means you can fit 5x engines on each supply run, or it'll take 5x less space.
Personally I'd love to see an actual list of things that are necessary to live on Mars, with difficulty to produce completely or partially charted out. What things have substitutes that could work etc. Saying shit like "not in 100 years" is short-sighted, since 100 years ago we were barely out of WW1.

An aquaponics set up would be the best candidate for food production because it uses just water in a loop with both plant and animal components
Methylacoccus bacteria already are made into a protein and fat rich animal feed and it feeds off of methane which would be abundant from fuel production so you bring in fresh carbon for expansion

I'm saying you likely CAN'T get free of having to import stuff as quickly as usually described in copypasta skipping over 9000 unknown variables.

It's part of why I don't see a point colonizing a poorly accessible red dead rock before we learn to do everything that's needed on a far more accessible grey dead rock that will make the process much quicker.
The most stupid thing would be to skip a step for a PR stunt and suffer because no one want to admit it was a bad idea.

>Personally I'd love to see an actual list of things that are necessary to live on Mars, with difficulty to produce completely or partially charted out. What things have substitutes that could work etc.
So would I. But we haven't (really) started making that list seriously and you'll take a while defining what exactly you mean by "live", how it differ from "surviving" or"grow".

My biggest problem with going for the moon first is that it's always 3 days away, which means there's far less push to make it be independent from Earth, since you can always get the shit you need in less than a week. A moon colony can also be cancelled far more easily, since again it's not that independent. Meanwhile Mars needs to be built from the start to be independent from Earth for at least 5 years. What's the point to dick around on the Moon for 20 years to figure out shit that can be found to work/not work with just some solution-centric thinking.

>you'll take a while defining what exactly you mean by "live", how it differ from "surviving" or"grow"
Surviving gets defined by the minimum amount of food necessary for each colonist + some safety margin. Not single crop either to ensure variety. Grow gets defined by how easily scalable the food production gets beyond the initial baby steps made with supplies from Earth. And not just food either but everything. The more people on Mars, the more problems can be resolved by people on Mars. A colony of 1000 people may not have the capacity to produce each small component that goes into making the colony work, but a colony of a million could, especially if everything that the colony is still depending on to come in from Earth is easily available in a list of shit still coming in every 2nd year.

>I believe the most important part will be bioengineering and actually understanding human biology. We have no future outside of Earth if we can't do genetic engineering on human and create a self-sustaining biosphere.

Odds are initially people will have to wear the same shit every day, and growing stuff will likely be limited to food for quite a while, since cotton thread etc. can be shipped from Earth and stored long-term.
Making metals is likely to be one of the first focuses of a Mars colony beyond getting a local food supply running, as metals are heavy and thus expensive to get from Earth. Pots/cups/simple tools would be the first on the chopping block once that would work, since it's not like you really need that super-perfect stainless steel hammer to get the job done. Shit that people were able to make with technology 2000 years ago won't exactly be difficult to get going once the intial hurdles are out of the way. The way I understand problems with getting martian metal forging started, it's all the flavors of alloys that you could want for various purposes, which again boils down to the earlier mentioned standardization to remove complexity.

That's quite hard to do because it depends on a lot of choices we never explored and a lot of work we never did.
Take a spacesuit for example, clearly we need some in a Martian colony, so a self-sustaining colony needs to be able to produce some from scratch.
What do you need to make a spacesuit? The only actual examples are the suits we currently use (plus those from the past), but they're not adapted to production from Martian resources: for example rubber is easy to find on Earth, but not on Mars (I guess spacesuits contain rubber, that's just an example anyway). Do we replace it with something else? Do we plant rubber trees in our colony? Hard to say which would be the more efficient.
And you have to do these choices for everything and their components, at every level (including tools, tools to make the tools etc.), including thing we don't even know what they will look like (what will be the ECLSS on Mars?). Additionally, as you mentioned, standardization will be super important, so the choices would have to take into account pretty much everything. Also we don't really know precisely the resources available on Mars.

Finally, even if we succeeded in making such a list (which would now basically include how the entirety of the Martian economy should work) whatever plans we make up on Earth would not survive the reality on Mars. The best way to get a self-sustaining colony is to have a Martian colony and let them come up with solutions to get the most things produced locally, which should happen naturally except if the transport cost from Earth is stupid cheap.

Could you fill a depression in Mars' surface (like Hellas basin or a volcanic caldera) with a thicker atmosphere? Would it escape too quickly to practically replenish?

>Electromagnet specs
In the future it is quite possible that an inflatable struc-ture(s)can generate a magnetic dipole field at a level of perhaps 1 or 2 Tesla (or 10,000 to 20,000 Gauss) as an active shield against the solar wind.
>Expected Results: It has been determined that an av-erage change in the temperature of Mars of about 4oC will provide enough temperature to melt the CO2ve-neer over the northern polar cap. The resulting en-hancement in the atmosphere of this CO2, a greenhouse gas, will begin the process of melting the water that is trapped in the northern polar cap of Mars. It has been estimated that nearly 1/7thof the ancient ocean of Mars is trapped in the frozen polar cap. Mars may once again become a more Earth-like habitable environment as shown in Figure 2.

Also the reason you don't think its that simple is probably from all the overhyping that popsci has done about the dangers of radiation and what not. They ramble on about how dangerous colonizing mars (or terraforming it is) but as I've said earlier, there are several components of martian terraforming that will be quite easy. The hardest aspect of terraforming mars will probably be getting large oceans, as the water reserves on the planet left nowadays are only enough for a relatively small ocean.

If it's actually this simple then it literally wouldn't be worth his time. Even a dozen Starship launches is a drop in the bucket compared to what he'll be doing and with that much mass to Mars he'd be much better off trying to sell them on a project way bigger than that.

This comes from the assumption there are no carbon deposits on the Moon, but since we've done fuck all actual geological exploration of the moon we can't say. I think its likely at least a few major carbon deposits of some form are located on the moon due to impacts from carbonaceous asteroids.

>independent
I really hope you meant self-sufficient by that because the one thing we don't need another of is a country of conceited settlers acting like they are the chosen people held down by everyone else.

>A moon colony can also be cancelled far more easily
Sunk cost fallacy and emotional blackmail is a poor way to justify a colony Mr.Zubrin.
A moon colony will be far easier to justify in the first place as it doesn't cost more and it build infrastructure for better space travel later and may even actually turn a profit for the rest of the world with resources from space (not even talking of Helium3 meme).
It's time to stop thinking small and build a giant interconnected economically profitable infrastructure instead of thinking how to trick others into paying X to play settlers down a lifeless gravity hole.

>What's the point to dick around on the Moon for 20 years to figure out shit that can be found to work/not work with just some solution-centric thinking.
Because trying to do that on Mars would likely kill peoples or take 200 years longer because of the slow rate of travel and Mars being not being as hospitable as the moon.
I fear you believe that being on Mars with "no other solution" will magically inspire engineering solutions and make production capability appear out of tin carbon dioxide.

>Survival/Grow
The time and effort ProMars expect to reach 1000 then 1M is usually grossly underestimated even if we produced Starship by the thousand and it have the expected specs.
Anyway, from there it become an long economic discussion wether starting with the Moon, Mars or somehow both is more profitable and quicken our transition into an interplanetary species.

>I really hope you meant self-sufficient
I meant both self-sufficient and independent. A colony that can only be reached by Earth once every 26 months has absolutely no need to be politically dependent on Earth beyond the minimum it needs for supplies.

>Sunk cost fallacy and emotional blackmail is a poor way to justify a colony Mr.Zubrin.
Apollo happened, and look how far we have come since then. A moon colony will unironically require more infrastructure as you can't depend on easily available resources that are present on Mars (CO2 + water ice).

>would likely kill peoples
Oh no! People might DIE!!!1! People die every day. Yes it would be bad for the colony for someone to die, but that's not an argument to never bother with starting the colony/first dick around on the moon for god knows how long until you're satisfied you learned everything needed to start a colony on a planet with a different environment and resource composition.

>Are you a Chinese Government Official free of ethic or safety concern?
No, but you probably are. I don't think we'll be doing human genome modification before/early into colonization to work better on Mars, I presume the refered problems are in materials/components segment with things like plastics that we take for granted on Earth that don't have substitutes yet.

>>12515892
>Would Humanity profit
Only humanity of concern (to me) are white europeans and very few select nationalities (japs with JAXA for example) that at least attempt to act in a civilized manner. What the filth of the world that never dreamed a sail would receive from the colonization of Mars is of no concern to me, in fact they should get fuck all if they don't contribute to the effort.

To be short I consider the resource of Mars and their accessibility to be grossly overrated. It will be as difficult as the moon with less access to actual solutions, it's all wishful thinking.

>Oh no! People might DIE!!!1!
Spoken like someone who is not held responsible for killing up to the whole colony to satisfy his ego.
Even if everyone "know the risk" or there's no screening for suicidal people, they and everyone else will be mad to learn you knew 10% of them were very likely to die.
Hopefully competent people will prevent that from being a possibility, even if it mean some red tape.

Everything you learn on the Moon will be useful on Mars and likely make it faster than spending all on Mars directly. Not counting the economic aspect since a Mars colony bring nothing back unless you go /pol/tard or wish for an all powerful Autocrat making money on Earth and spending it on Mars for himself.

>I don't think we'll be doing human genome modification before/early into colonization to work better on Mars
Latest research still suggest human will have terrible health trying to live with lesser gravity.
But yes it's also for organic compound and life-support.

>You sound like either a chink or a liberal that thinks we should spend as little as possible on space and always "think of humanity".

Good thing the people that want to go for Mars directly can choose to do so, while people that share your opinion of trying to do things as carefully as possible with the moon first can also choose to do so.

>killing up to the whole colony to satisfy his ego
That would be a catastrophic failure that would be obviously bad, individual/small group deaths because of work accidents etc are of no consequence though. Should obviously be minimized where possible, but a lot of jobs on Earth already carry a risk of death and we don't scream for the economy to stop until that risk is removed.

>Latest research still suggest human will have terrible health trying to live with lesser gravity.
I'm not aware of any research that has been done on the effects of lesser gravity beyond 0G experiments on the ISS. Unless you mean some paper someone shat out to satisfy their publication quota. There is no data either way on whether 0.38G is enough for humans or not.

>closet-racist
I'm not trying to be closeted about my opinion at all. And you're the one who brought up the chinese with unrestricted bioengineering development. You're right though, you sound way more like a neo-liberal than a chink.

Sure, but Orion is not a good launch vehicle regardless because it's too expensive. It would be cheaper to launch 10,000 tons of payload using 100 Starship launches than a single Orion launch. There'd be less radionuclide fallout, too.

Orion, and all other high Isp propulsion systems, are best used when they are the cheapest or only practical option. Basically, anything you CAN do using a reusable chemical rocket, you SHOULD do with a reusable chemical rocket.

Fusion energy will likely cost as much as fission energy, maybe a bit less per kWh. The thing about a fusion energy economy is that it only really hits crazy levels of economics after you've shifted enough of your materials manufacturing and transportation industry over to your new, cheaper power source, and get all the knock-on effects in all of those industries combined. For example, 1 cent per MWh fusion power plants would be awesome, but we literally cannot build something that economic unless we're already using 1 cent per MWh supply to do everything from mine the iron ore to smelting it to producing all of the tight tolerance parts etc etc. It's a bootstrapping problem, you can do it but it takes iteration, which takes time.

The big problem is that unless you are willing to take on every single industrial process at once as a nation, you can only work through this bootstrapping process as quickly as the third world countries where your cadmium comes from can keep up. Globalism is a great way to slow the development of individual nations down in a big way, by having more developed nations spending more time and energy 'helping' less developed nations.

By building a Mars or Moon colony though, we would effectively be building a new first world nation with high technology and a strong focus on economic industry and bootstrapping, which would have no local third world failed states to prop up. This means that in general, we would expect to see space colonies grow fairly quickly at first as they are fed by Earth economies, and then have their growth and development rate explode as they reach self sustaining levels of complexity.

>Nuclear bomb don't conveniently become harmless or vaporize debris just because you think it's would be convenient.
Learn english lmao.
I don't *think* this shit, this is commonly understood physics. Inside of a certain radiation flux, temperatures will reach a point at which no materials can exist even as a gas, they become broken down into plasma. This level of irradiation is present in a volume larger than the volume of the explosive, when considering the power output of a nuclear bomb.
Regardless, even if you imagine gram-sized chunks of material impacting your pusher plate, the result would be cratering and pitting, and the design solution is literally just "use a thicker plate". However, like I mentioned, this WOULD NOT HAPPEN, because it is IMPOSSIBLE for any bomb material to not be fully blasted into plasma, because of the intense x-ray flux. I have literally studied nuclear physics and the effects of intense radiation flux on materials in post secondary school. You are some guy who can't accept that chine would ever bend the knee to global politics and avoid building a nuclear bomb powered Orion-style spacecraft.
