What does sfg think about places other than inner? https://en.m.wikipedia.org/wiki/Colonization_of_the_Solar_System
For me, its ganymede

>>14965002
Ganymede has water, some rocks and... that's it. I suppose it's better than having just water like on Europa or Callisto or just rock like on the Moon. Titan is one of those places where it wouldn't be that hard to build a base. Humans wouldn't have to live inside pressure vessels and oxygen is available from the ice, if you have the power to process it.

>>14965009
Titan is sat(an)ian so the people there will become demons.

>>14965009
>Ganymede has water, some rocks and...
a killer view of jupiter

>>14965009
It has lots of radiation
Maybe we could use it for energy or something

Meanwhile in China...

>>14965068
Unless a western country successfully launches an abomination like this first there's zero chance the Chinese are building this. No, renders don't count.

>>14965002
>>14965009
This article is amateurish.
>Io is not ideal for colonization, due to its hostile environment.
Io will kill you within minutes of being there, this is a huge understatement.
Ganymede and Europa aren't as bad, but it still is too much radiation.
Callisto is both outside the radiation belts and has a good balance of rock and ice. It's the best and only realistic target for human exploration on Jupiter.
Venus has almost no hydrogen for making water, and Mercury colonization is completely pointless.
I can't find information about the radiation levels on the other outer planet's moons, but I guess most of them have the same problem.
Also, I think Titan's atmosphere might actually be a problem since it will require more energy to keep the astronauts warm.
The only good places in the outer solar system are Callisto and Ceres so far.

>>14965054
solar radiation?

>>14965152

>>14965177
Is there a soyuz under all that paneling?

>>14965177
Oops, all launch escape tower!

>>14965172
Still, how much radiation does Titan gets and how much is filtered by the atmosphere?

>>14965152
Sort of, but not really. Like Earth has the Van Allen Belt of radiation, Jupiter has a much larger and more intense belt of radiation created by the interaction of it’s giganigga magnetosphere with particles emitted by it’s moon Io, and particles from the solar wind. Io is the innermost of the major Jovian moons and is the most radioactive, you’d die multiple times over from the radiation levels at the surface, and Ganymede is the thirdmost distant, it’d take a few months to kill you. Of course, you’d be fine under the surface with several meters of material, particularly ice, between you and outer space.

Just use more shielding. It's not that hard.

>>14965342

>>14965348
You can still just use more shielding.
But just out of curiosity, how much effort would it take to drain Jupiter's radiation belts?

I had a dream that the Antares was carrying an orbital Blue Origin capsule with crew on board and one of the engines blew up so they had to abort, but when they went for reentry they couldn't adjust their attitude so they burned up.

Just bring your own personal magnetosphere, it can't be that hard.

how long can we expect to wait until they restack?

>>14965288
Isn't that gun supposed to be red?

>>14965441
EVA might not even be necessary if the docking ring allows for crew transfer. Just go belly to belly, pop the hatch and float into the other vehicle.

>>14965593

>>14965581
>they run out of rockets next year.
in your dreams retard

>>14965589
It actually is. I used estimated dry mass and propellant weight figures from the first sources I could find, the isp. for the NK-33 that's listed on wikipedia, but I think I misentered one of the mass figures. The real figure should come out closer to 2.3-2.5 km/s, but in practice it'd be somewhere below those numbers since the calculator I used doesn't figure losses from atmospheric drag or gravity.

>>14965604
Highly probable, but I am not-so-secretly hoping that they develop rocket proonting tech to maturation, such that it yields unexpected benefits that cross-pollinate into other rocket companies.

How will we produce babies on mars?
The amount of women that will come is very very low
Oh so that's why Tesla is making a humanoid robot and Elon is so worried about making babies
The man really thinking of everything

>>14965614
They've got two Ariane 5s left, and they only have enough RD-843 engines for maybe three more Vegas. They don't have Soyuz anymore. The Ariane 6 is getting delayed like its SLS and Vega-E won't have a domestic upper stage engine until at least 2026. What rockets are they going to be flying, champ?

>>14965630
Ariane 6

>>14965631
Which has been delayed until Q1 2024, and is all but certain to get delayed further than that. Rocket programs don't deliver ahead of schedule, especially when they're run by a bureaucratic mess like ESA. If Europe was going to have its own rockets available anytime soon Hera and Euclid wouldn't be launching on Falcon 9. Europe is going to have to start launching Galileo satellites on Falcon 9 soon too if they don't want their constellation to start falling apart.

>>14965068
I'll believe it when I see it launch.

>>14965642
>C'mon now, it worked in KSP

>>14965648
Okay, let's see your version of it in KSP then.

>>14965620
Thanks. Seems like SLS is more powerful than N1 then. To get the max power we multiply the velocity just before staging by thrust.
SLS - P= 39 MN x 1.4 km/s
N1 - P= 45 MN x 2.4 km/s

What makes Americans pissed is that they could out-compete china in every facet of life if they weren't cockblocked by bureaucracy and corruption every step of the way. Take SpaceX as an example. But even in a state of implosion, the USA is still better than China, and this is just as notable- though I still would not diminish the efforts of the Chinese, as it is equally as respectable as it is threatening to Martian colonization prospects.

>>14965941
Now that I think about it, it doesn't make sense. They have the same internal structure as the rest of Ships.

is terraforming a planet unironically being considered by any professional? Wouldn't building a simple space station be a billion times cheaper, faster and more reliable of a habitat?

>>14965956
Why would they have different internal structure? They don't need to complicate things just to try out orbital propellant transfer.

>>14965958
"professionals" (including Neil A et al.) didn't think private spaceflight should handle sending cargo to the ISS 10 years ago
it's less that it's being tackled by professionals today and more that it'll be in the latent subconscious of every person who lives and dies on Mars

>>14965959
They don't even have a docking port.

>>14965936
so both methane and lox header tanks are combined? in the nose of the ship, and bottom of booster

>>14965958
If by "terraforming" you mean "turning Venus into a jungle world with busty women in bikinis like in Edgar Rice Burroughs porn" than, yeah, no.
If my "terraforming" you mean "colonies and mining operations on our own Moon that we can inhabit for weeks at a time" then, unironic yes.

>>14965962
The first demo listed in their HLS development program is just inter-tank propellant transfer while in orbit.

>>14965958
Think of it like the early days of age of exploration.

Should columbus have created a civilization in the middle of the atlantic ocean by transporting a trillion tons of land/infrastructure from Britain? Or should he go to America and create a city there?

Its a question of how you want to start your civilization. Is it easier to move yourself to Mars with 1000 Starships or move Mars to you with a trillion trillion starships?

>>14965941
then why do they have header tanks?

>>14965958

>>14965983
Its easier to transport a million people to a trillion ton land than transport a trillion ton land to a million people.

Starship could be transformed into a space station, it could support few lives, but everything needs to be sustained through transport from Earth.

Whereas Mars has the potential to be self sufficient with very minimal support from Earth and be able to support billions of people potentially.

>>14965970
>terraforming Mars
Could governments paying Starship (reasonable price if it can be used to terraform) to transfer biowaste landfill mass off earth to Mars contribute to terraforming mars, you wouldn't want the colony near the garbage dump, but could it grow and spread over decades and if littered with seeds could it grow a soil layer and start atmosphere system?

Cheers, you lunatics!

>>14965983
Start with KREEP: Potassium=kalium, rare-earth elements, phosphorus. Nobody gives a shit about K but the REE and the P have value. Note that lower-gravity and no-air make some chemical reactions easier than on Earth, so the rare-earths (which yes yes aren't actually rare) might be more easily refined on the Moon. And phosphorus has been flagged as a nonsustainable resource on Earth due to heavy use as a fertiliser.
Move on to the many many Lunar craters which probably have meteorites in them. Some must be metallic.
I mentioned the low Lunar gravity and atmo. This means we can use railguns or SpinLaunch to get cargo off the Moon into an Earth orbit, without propellant - just energy, which can be had from the Sun and batteries and/or capacitors. Supplying Earth-orbital stations from the Moon (especially higher orbits) is cheaper than from Earth.
As we get a space (Earth-orbit) economy, supplying it from the Moon will become cheaper than from the Earth.

>>14965992
Now, I see what you mean. However, I think a space station could be autonomous and up to a number of inhabitants, it would be cheaper and could be built faster. Provided, it's inhabited by people who know how to maintain it, it can supply itself with its own energy (either solar or nuclear) and you can grow food there.
Another question: Why terraform a planet? Why not burying yourself into the Mars's surface and living undergroud?

>>14965358
tough but fair punishment

>>14966012
If it's so profitable, then why is no one doing it?

>>14965991
Depends on your definition of "simple space station". Usually when we argue here it's between O'Neill cylinders vs terraforming planets. By the time humanity has the capability to construct such a megastructure it would be utterly useless as fully biological humans will be a minority. Unless the AI star children build them for fun. Terraforming can be accomplished with current technology, and factoring in accelerated innovation you could probably turn Mars into a second Earth in a century or two.

>>14965997
No, it will all instantly dry up because there is barely an atmosphere. That's the one big thing you need to solve first.

>>14966013
To make a space station autonomous, it needs a lot of mass. To get those mass, you need to have lot of ships to transport those mass to get a sense of autonomous space station and it would only support a small number of people.

To scale up/sustain a spacestation with million people, the amount of mass needed to be transported is enormous. Where as on Mars, the majority of mass is on the surface.

Water is on mars, land on mars, majority of chemicals on mars, with very little bootstrap infrastructure required to get food growing.

The cons of Mars is that its far away, the cons of spacestation is it cant sustain many and would be extremely inefficient to sustain lot of people.

He had different idea of human space industry. didn't take into account of cost of transportation for one.

If transportation cost as 0(money/time/propellent/etc), then you can make a city anywhere in space rather than on a planet. Thus it makes more sense to do it from scratch to your perfection rather than try to bootstrap a dead planet.

I'm with Zubrin on this one - Saturn and the ice giants are the best places past the main belt. Mining the Jovian system will always primarily be done with robots, since the Trojans don't have resources for life and Jupiter's radiation is hell anywhere closer than Callisto.

>>14966059
Still feel like bootstrapping a civilization on a planet makes more sense than bootstrapping out of free space. you basically have to "build a planet" first in a sense, then you have to power the whole fuckin thing, keep it climate controlled, somehow keep it self-sustaining. my guess is you wouldnt be doing hard industry in there, so you did all this work to build a glorified park. this is like an Arabian oil magnate's idea of utopia, a giant soulless empty trillion-dollar oasis in the middle of nowhere

I just can't stand the space colonization meme anymore.
There is currently zero financial benefit in going further than Earth's orbit. Moon He3 might be just BS, asteroid mining is not financially viable and there is nothing to get in the planets that we can't already get here for cheaper.
The only other reason to get out of Earth would be to look for something better, but nothing in the Solar System will be better than this. Terraforming is way beyond our technology and resources and living in habitats will be too expensive for something that will be essentially living in the pods.
The only realistic near future we have is research stations that extract local resources for survival, without a permanent population.

>>14966115
Not true. There's a many benefits to offworld colonization:

1. We'll need to invest heavily in genetically engineering crops to survive extreme conditions. As our planet undergoes climactic extremism due to the last hundred years of fossil fuel burning and environmental destruction to facilitate the growth of the species, that has led to a lot of destabilization effects across many climates. This is going to have profound effects on crops and human migration over time. The ability to vertically farm and scale farming to arbitrarily large levels is crucial to the long term survival of the species. Colonizing another world forces us to tackle these issues "today" vs "tomorrow", so that in the event of a major crisis, we have an avenue to deal with it in a way that doesn't destabilize the entire world.

2. Colonization of another world requires a vast amount of energy. The largest energy generators on planet Earth today are nuclear reactors, which are the size of a small town. We need to invest and improve over time, the means by which we can condense and control the reaction and energy production into a physical footprint 90% smaller than present implementation. In achieving that, you can then scale that out to 10x the footprint on Earth and 10x the footprint elsewhere in the solar system. It solves major energy crisis eventualities in advance, and an abundance of energy allows you to electrify the grid faster and allocate more resources to solving the fusion problem as there's less dependence on fossil fuels and capital is better allocated to problems that matter.

3. Extreme conditions will require human genetic engineering through gene therapy. That has positive feedback loops to Earth in that solving issues occurring offworld can be applied to genetic defects, disease, and improving quality of care due to injury or trauma locally.

4. Hostile nations own majority deposits of rare earth. Belt mining decouples that dependency = improved world stability.

Lack of oxygen is a trivial problem to solve: https://i.insider.com/5b02dabc1ae6621d008b4830?width=1000&format=jpeg&auto=webp | there's enough water in the solar system that with enough energy (which if you fix the fission and eventual fusion issue) you can split to get the oxygen you need. The limiting factors are nitrogen. Getting 70% nitrogen is going to be the harder part.

>One gigawatt is enough energy to power about 750,000 homes.

So an average nuclear reactor can produce 13.96GWH of energy or enough to supply 10.5M homes. On average, energy distribution follows the 80/20 rule. This means 80% for industry, 20% for residential/commercial activities. Thus, 13.96 aka round up to 14GWH @ 20% yield means an average reactor can supply 2.1M "homes" on Mars. However, due to the hostile environment and additional survival necessities, we will reduce that number by 75%. This means an average nuclear reactor can produce enough energy to support: 525,000 "homes".

Speaking about Mars specifically, most if not all of the mass for a fleet of a thousand synchronous-orbiting spin habitats at Mars would be easily sources from Phobos with barely any delta V expenditure whatsoever, you simply build the entire station next to Phobos then move it to an aerostationary orbit and build the next one. At most you'd need to mine Mars for the more scarce elements and compounds you need which can't be produced from whatever Phobos is made of.

>>14966084
You're correct about the resource thing but you're envisioning the space habitats wrong. They aren't out in the middle of nowhere, they're within easy reach delta V wise of a source of resources and industry. Most of the time when people talk about space habitats they are talking about them in the context of colonizing the asteroid belt, gas giant moon systems, or the Kuiper belt. In all three cases the fact is that there's no nearby rocky object with strong enough gravity to be comfortably lived upon for one's whole life (presumably true in the case of the big Jupiter and Saturn moons but definitely true everywhere else), and in that case the low gravity of objects works in your favor by making launching resources off of them much easier.
The asteroid belt in particular is very well suited to colonization via O'Neil cylinder based civilization because those habitat structures would effectively be able to skip between chondritic, carbonaceous, icy, and metallic asteroids on a whim with extremely little delta V cost, and thus have access to basically any elemental resource imaginable for very low cost. Once could fairly easily imagine habitat complexes with rotating or zero G factory modules in tow which would build more habitat and factory cylinders over time and eventually release them to go on and free float and mine their own resources again, almost like a scaled up version of microbial division.
For other situations such as the Saturnine system we could imagine a pioneer colony on the surface of a smaller object constructing spin habitats and factories which go on to continue mining the other objects while building out more habitat volume over time, setting those habitats to orbit in some convenient way, say with a majority inhabiting a ring between Rhea and Titan while a few dozen others take cycler orbit paths between various moons to act as regularly scheduled transport ferries.

The combined total cosmic ray dose of a 3 year total Mars mission, assuming 12 months in deep space between planets and 24 months on Mars' surface with no overhead shielding, would not be injurious to a human. Simple as. The solar charged particle dose can be ignored as long as you design your vehicle with a radiation storm shelter using food and water as your absorbing materials and you hide in it when there's a CME or similar event.
The radiation in space is not a big deal, and the fact that we don't have a hundred years of data from a million subject of 36 ethnic backgrounds and ages from 5 to 90 years to do statistics on does NOT make it a big deal. It's currently at the level where it warrants signing a waiver before going.

>>14966588
Because they offer no advantage.

You're walking back to base during the early months of the first mars colony, communication comes in: "there was a miscalculation and spill of tanks, it turns out we only have enough air supply for 6 days. The nearest starship is estimated to land in 1.3 months. "

>>14966624
How the fuck are you going to land on something without understanding is properties first?
For Enceladus I get because we already had Cassini, but If we don't study from orbit first we risk sending an expensive lander that will just fail because we didn't understand the physical properties of the body.
If you want fast missions, then first you need to cross your fingers that Starship will work, then hope they can get more funding. The current state of spaceflight limits you to having to gravity assist for a decade before arriving, there isn't much that could be done unfortunately.

>>14966603
>I remember reading something about Enceladus having high radiation but I'm not sure.
Enceladus is close to the region of greatest radiation density in Saturn's magnetosphere, but this is still a weak dose rate since Saturn doesn't have much radiation around it in the first place, simply because there's so much dust and gas spread out orbiting Saturn that it absorbs most of the high speed particles.

>>14966630
Why only 6 days? Why not 1 seconds worth of air supply left?

>>14966630
It's too easy to produce oxygen from CO2 for any "Oh no we have no air!" disaster scenario to be feasible.

If you build a big enough habitat/vehicle, the mass fraction of a solid five meter thick jacket of shielding becomes negligible, and in fact at the largest scales it's completely free, because the side wall of your habitat needs to be so thick in order to handle the tensile stresses that it doubles as a shielding layer capable of blocking even the highest energy cosmic radiation particles.

Solar wind is very sparse, yes, BUT it's also a moving charged fluid and therefore can be redirected using electromagnetic fields, which (if you have the energy) can let you build a collection scoop hundreds of thousands of kilometers across. Also, it may be possible to use the solar wind to power the electromagnetic collector, if we can take advantage of the magnetohydrodynamics of the system. This would probably require "wasting" 90% of the incoming mass stream in order to direct and capture the other 10%, but if that total mass flow rate is several thousand tons per second due to the scale of the capture array, maybe that waste doesn't matter much.

That's fucking stupid, just have some internally stored emergency breach covers which are packed in storage ready for deployment. Make them from a 50 meters by 50 meters 3 inch thick 3D woven kevlar sheet with a backing network skeleton of watertight kevlar tubes. In an emergency the nearest few breach covers are deployed and have their tubes pumped full of water at high pressure. The covers are then lifted over the breach and simply dropped in place. The gas pressure inside the habitat forces them down onto the structure surrounding the hole, forming a temporary seal. A peel-and-stick strip is laid down on the edges of the breach cover to improve this seal. With the emergency over, a larger and more robust internal hull repair unit is brought to the breach site and installed over the temporary breach cover, where it forms a nearly perfect seal and provides access via airlocks and so forth. The air is removed from inside the repair unit, the breach cover is removed, damaged sections of hull are removed, the hull is repaired, testing is completed, air is replaced into the volume, the hull repair unit is moved back into storage, and finally the hull is covered back up by cosmetic layers to match the rest of the interior of the habitat space. Simple as.

Ganymede would be fine. You'd have plenty of time to come in on something resembling a hohmann transfer from a far Jupiter orbit, brake into Ganymede orbit, propulsively land, do systems checkouts, and deploy a simple microwave based water vapor collector to fill up an overhead shield blanket surrounding your habitat space. In fact, this would probably not even be necessary, because as is the case everywhere in the Jovian system, the radiation flux is well over 99% composed of easy to block charged particles which don't produce secondary radiation unless they interact with incompatible materials (such as lead or tungsten for example). A layer of HDPE plastic a couple inches thick coating the entire habitat volume of a spacecraft would likely be sufficient to protect humans orbiting in the vicinity of Europa, let alone Ganymede. Like I mentioned however, once a crewed spacecraft lands anywhere on Callisto, Genymede, or Europa, very likely the first thing they'll do is set up water collection and grant themselves unlimited shielding capability. The nice thing about water is that it's not only hyperabundant everywhere beyond the asteroid belt, it's also a liquid under the normal operating temperatures of a human spacecraft and therefore if you are using it as shielding in your rocket while on those objects you can simply vent it overboard before re-launching, if that's your architecture.

you fail to seperate the individuals working there from the institutional problems.

There may be a relation, but most of these guys are so far removed from the institution's policies (which are the root of the problems) and the policymakers that set them that they might as well be working for a hired contractor.

I've seen better looking and more realistic concepts made in MS paint

>>14967333
It's just for show, their actual plans are copies of Falcon 9, Flacon Heavy and Starship/Booster.

Cute trashcan

Berger says its a nothingburger, false alarm. As soon as SLS launches, Starship will be allowed to do a suborbital test.

Yes most of the people who got swept up in shuttle fever back in the 80s and 90s are hitting retirement age. Their replacements are few and far between (and frequently get lured away by private sector opportunities).

NASA's R&D side skews a bit younger though.

china is at least 15 years behind the US in spaceflight, maybe even 25 years

>>14967177
why aren't they rolling it back?

>>14967477
It makes me seethe when USA politicians are so proud of their space shit, but still are so openly averse to spaceX which is the only responsible of having a good space development of their country.

the only thing they have going for them is number of launches

Forgot that shit.

>>14967545
Seriously though, why hasn't the Chinese Space Agency attempted solar sail craft tests yet? It seems like the obvious (untested) next step to BTFO everyone, and surely they can produce the tech.

>>14967558
>and surely they can produce the tech.
No, but they can steal it.

china should take advantage of totalitarian state.
start building experimental pulsed solid core rockets.
doesn't matter if a few hundred people die and no other country will fuck with you.

To independent-minded voters:
Shared power curbs the worst excesses of both parties, therefore I recommend voting for a German National People's Party Reichstag in March 1933. Hardcore SPD or NSDAP supporters never vote for the other side, so independent voters are the ones who actually decide who’s in charge!

>>14967567
this is the way to leapfrog the US and become the space superpower they like to larp as.
would require innovation and risk taking however...

>>14967496
SpaceX is at least 2 decades ahead of the rest of the world at the best demonstrated pace of development of those other organizations, and SpaceX is an American company, so yes America is two decades ahead of the competition at least.

>>14967574
(you)

>>14967579
SpaceX is less than a decade ahead of rocketlab and relativity. (which widens the US lead even more)

>>14967558
Solar sails actually suck in real life when you need to deal with real life conditions, and they are especially useless at small scales where just putting the same payload on a bigger rocket design you already have can get that payload to its destination faster. For an analogous situation as described above, see the DART mission and its ion drive which was originally a vital part of the mission but got relegated to a 2 hour tech demo because the Falcon 9 was able to just throw DART directly at Didymos.

>>14967582
You almost disagreed with me but then I realized you meant that the three most cutting edge space technology organizations on the planet are all American, so I forgive you.

>>14967582
>SpaceX is less than a decade ahead of rocketlab and relativity. (which widens the US lead even more)
Rocket Lab is visibly more than a decade behind SpaceX.

The next Speaker of Congress is a pro-Musk, so it could be good for SpaceX and Tesla.
