India doesn't have the technical ability or the budget.

Japan has the ability (maybe) but not the budget.

Europe has the ability and maybe the budget but they're hamstrung by being an inefficient weirdo socialist operation that cares more about jobs distribution than product performance. They'd reject building EuroRaptor if it wasn't a jobs program for half a dozen different countries.

Russia used to have the technical ability but they lost that when they spent three decades coasting on inertia left over from the old soviet glories and all of their good engineering talent emigrated or died.

China pretends that it has the technical ability but i really doesn't. You only need to look at how they've kept revising down their expectations for the CZ-9 main engines to see that.

The UAE is rich enough to hire the talent they'd need, but instead they're playing it smart by sticking to making payloads and leaving launch and propulsion to other groups.

Other corporate players would like to and they've got enough talent to at least try but don't have near enough cash flow to make the attempt. Most of them are looking bankruptcy in the face just trying to keep their current SLV operations going.

The base state of individuals/teams/companies/countries is mediocrity. If they're not driven, they become like the DMV, or any other monopoly-- ho-hum.

SpaceX is REVOLUTIONARY and special in 3 ways:
1.) Mission. They actively work towards their goal: They want to make humans a multiplanetary species. This needs kilotons of mass delivered to Mars. So make a cheap, reusable rocket! And use that rocket's capacity to make money to pay for all the stuff you'll deliver to Mars.
2.) Iterative design. Lots of companies SAY they're agile, but SpaceX really IS. In the time it took oldspace to rebuild a Frankenstein shuttle using 50 year old tech, SpaceX will have built a totally new engine, spaceship, and factory.
3.) People. SpaceX is the best place to work if you're a smart, motivated engineer. If you're 22 and go to Boeing, you'll do menial shit under someone as old as your parents (or grandparents!), for years or decades before you do meaningful engineering work. At SpaceX, your boss might only be a couple years older than you. You'll probably work on interesting things quickly, and actually contribute to your project.

right, it is a lot of hours, but they're productive hours. It's not just ass-in-seat time, or making a nice powerpoint for some executive. It's getting real stuff done. If you're in your 20's and haven't started a family yet it seems like a great place to work. It's like 1 year at SpaceX you might learn more stuff than 10 at Boeing, and your SpaceX skills/experiences will translate to you being very productive wherever you land after SpaceX (when you have a family, for example).

I think this stuff is actually one of the reasons they're successful -- they filter out anyone who just wants a paycheck. They filter out anyone who has significant non-work commitments. They only get enthusiastic people. It's night-and-day to work with lifers (just there to collect a paycheck) vs believers.

>>14730070
I kinda do too. I spent my 20's in consulting, so I worked crazy hours but my work didn't really have the same impact as making humans multiplanetary. And at the time I didn't have the skills they needed. Now I have the skills but I'm married with kids so work-life balance matters a lot more to me now. I still dream about it but know it's not really an option for me anymore.

One of Von Brauns stories about why he was arrested by the Gestapo and ultimately blackmailed into the SS was that he had claimed at the party that the future of Rocketry was in Florida and that he would leave for the US as soon as the war was over for their huge budget potential. So it might not look so different but that story did vary fairly widely over the years.
The main positive would be he and the American Peenemünde boys wouldn’t be locked in Redstone being ignored and sidelined at all costs by competing military RnD teams for 15 years.
There would be no Russian Space Program and no Cold War to drive the objectively ridiculous 1962 to 1968 budget however but that might be mitigated by the lack of Foreign Aid nation bankrupting after that date.

straight-wing shuttle report: after spending 0 hours on aesthetics and 6 hours on reentry i think i finally got something that can hold the 60 degree angle of attack proto-bellyflop until it's subsonic. you have to keep the center of lift really close to the center of mass.
it's really pretty stable once it gets down into the thicker atmosphere past 75 km if you just fiddle with the slider for the tail elevators to try to keep pitch meter centered.
switching from the flop into level flight is still a problem but i think it's just a matter of figuring out what order to press buttons in and probably getting some bigger jet engines. on the tries where i successfully recovered from a stall it flew just fine.
payload bay is tentatively 9.5m diameter and 20m long, which should be enough for about 100 tons of LH2. only problem is i'm not sure how to open it. i'm probably gonna have to pop the nose open uragan-style with some robotics parts.

What can China do? They're stuck. Their economy is too closely coupled with the West. We can always find another poor country to do our manufacturing (which would suck for a while), but there ISN'T another rich world to buy their goods. China is sitting on a demographic timebomb-- people are just now realizing that the one child policy will be FAR more damaging to them than the Great Leap Forward.
>>14730092
I think their best bet is to fast-follow Starship, especially once it's more mature/actually working. But even copying it is going to be very hard. China still hasn't figured out how to make jet engines as good as the West or even Russia, and they've been trying to reverse engineer those for decades. Rocket engines are probably even harder than jet engines, so thats a big problem. Probably using a simpler/less efficient engine is their best bet, like gas generator anon suggests.

Tesla isn't even close to any "exciting" problems of whose life to prioritize when some kind of collision is evitable.

You're also wrong on your rationals as well.

Tesla autopilot rear ends emergency vehicles because the autopilot ignores those, not because its a limit of vision but because its a limit of the old software they were using. There's two different software at play. One for autopilot (old software) and one for FSD (new software). Autopilot is rudimentary lane keeping with some avoidance and some lane changing. It ignores complex dynamic aspects because on highways those are extremely rare. Meanwhile on FSD (new software), the car keeps track of EVERYTHING. Which requires a more robust software and is more prone to erratic behaviors due to sensititive to data, thats why they're testing it out on the city streets with this. The reason the they aren't using their new software on highway is because autopilot still does the job 99% of the time, but the new software is getting there to replace the old software soon. Not because its impossible for vision to drive the car, we've already established that cars can drive on cameras alone. FSD drives cars on city streets all the time now, there's thousands of videos online. Just sort by latest monthly videos. Its a matter of time when emergency vehicles are displayed, not that Musk's vision only is impossible as you claim it is.

Honestly why would ANY new space company try to build a rocket engine using anything other than the gas generator cycle? Even Rocketlab has stated that GG is very simple compared to anything.
My guess is that the entrenchment of kerosene fuel is to blame, except if you're building a small rocket you can very feasibly supply a few dozen tons of propane fuel per launch, so really it's more that new guys are afraid to break from the status quo. Looks like moving forward from here though the fact that methalox is becoming the new industry standard will mean that anyone trying to butt into the market is going to have an easier time doing it because they will pick the GG cycle and not need to deal with soot formation at all.

>Choose a safe location with resources like ground water ice;

>One of them is the crew;
>Some others are hardware like a oxygen factory, a ground ice extractor, a power generator, shelters etc;
>The rest is all supplies of oxygen, water, food so that they won't die if the hardware doesn't work as expected;
>The crew will focus on setting up and testing the hardware for future missions;

Subsequent mission would gradually increase the size of this outpost, initially with pre-built modules, and then using local production for stuff like roads.
Mars would be explored through vehicle voyages starting from this outpost, where every landing and launch would occur.

Not with the way the field is currently structured no, not at any realistic price point anyway. US astronomers actually get paid for using major space telescopes, to support their research. Most of the time there is no exchange of funds. researchers themselves don't really have that much money, the majority is tied up in facilities at the national level. What astronomers have to potentially buy time with is pennies compared to the facilities budgets of ESO, NSF astro or NASA. So it doesn't really make sense to try and sell time directly.

Is it? I really doubt that Martian regolith can support plants. Even with imported soil you'd need a fairly major operation to actually sustain a colony, and it would also require large amounts of oxygen and water, both of which would be in short supply.
>water is fucking everywhere as ice (no, digging up ice is not so hard that it makes civilization impossible)
Almost all of that are in the polar regions, and would almost certainly be toxic if ingested directly. Mining ice and purifying it into drinkable water on a large scale would require serious machinery.

[Anonymous No.14732703]

>>14732685
>15x higher than the limit
Not when you are indoors on Mars, which is 99.99% of the time.
>is it?
yes. You don't need to import soil, you don't even need soil to start with. You grow food in water, via hydroponics and aquaponics, to start off. Afterwards, as you build up an inventory of plant biomass, you can make your own soils in situ if you want, by mixing decaying plant matter with regolith you brought inside and washed. To wash regolith you mix it with water to make a slurry then agitate the slurry for a few hours then let the sediments settle and send the water over to be filtered (removes salts and metals). You repeat this several times and you have completely nontoxic sand and silt that forms humus when mixed with organic material.
>polar
Mars' subsurface is loaded with water ice deposits down to the tropics on the planet, it's not confined to the poles.
>mining ice and purifying it would require serious machinery
Mining enough water ice to satisfy the needs of a colony that recycles all of the water it uses in life support would be accomplished by a single skidsteer sized earthmover and a vacuum distillation system, where the little excavator loads busted up permafrost chunks into a vessel which closes a lid then applies a heating element, vaporizing the ice inside and drawing the vapor off to a cold trap in the vessel nextdoor. The result is highly pure water, with a waste product of dessicated regolith.
Also, you may not have noticed, but everything in your life right now takes serious machinery to keep you alive, and everything else involved with getting to Mars and living there would require serious machinery, so your point is pretty meaningless in my opinion.

Unprotected by anything, the daily avg is 0.7 milliSieverts. A stomach cat scan gives you ~10 millisieverts. That's 14x the radiation you get per day on mars. So 14 days of unprotected radiation on mars = 1 cat scan.

Mitigations include staying indoors, wearing anti-radiation suits, etc. We can also augment the vehicles with small magnetic shield to deflect the radiations as well, so that exposure time for those inside vehicles are reduced to a fraction of radiation. Portable radiation for vehicles/human suits could be had with little powerpacks.

No we cannot, but it doesn't matter because you can easily just wrap your vehicle in a 6 inch thick layer of water or an 8 inch thick layer of sandbags to achieve good shielding. Yes this adds weight and reduces mileage from a single charge in your vehicle, but it's not a big deal. Future land vehicles designed and built on Mars could more resemble ships than cars, and in that case a 12 inch thick layer of external shielding wouldn't even add 1% to the total mass of the thing. Plus, at that scale a 50 megawatt nuclear power source that lest you drive for years straight would be easy to implement.

When will this meme die?
Earth's magnetosphere does NOT protect us from radiation. Earth's atmosphere does that. This is why the radiation environment on an airplane is significantly higher than on the surface of the Earth, and it's why standing at the north or south pole, where the magnetosphere actively INCREASES the amount of radiation raining down toward your head, does NOT dose you like crazy.
What Earth's magnetosphere does is prevent one of several atmosphere-stripping mechanisms by deflecting solar wind. It does nothing to stop cosmic rays and it doesn't protect the Earth from getting blasted by radiation. All it does is prevent the solar wind from ionizing the thermosphere and leading to significantly higher rates of gas losses to space. On geologic timescales, this has meant out atmosphere has remained thicker than it otherwise would, although Earth's high gravity is actually doing most of the work there too.
In short, would a personal electromagnetic field help protect you from radiation on Mars? Absolutely not. I'm not suggesting physics is wrong, I'm saying you are wrong in your understanding of physics, and that's because of extremely poor quality science communication to the public.

straight-wing shuttle report: payload bay is kinda working but the infernal robotics hinge refuses to lock when i hit launch no matter how many times i tell it to lock in the VAB, which leads to the nose cone drooping down inside the bay and sometimes causing the stack to start wobbling and mildly explode.
in theory the booster's a simple problem compared to the orbiter but the lack of relightable ground engines in the game makes doing a boostback a lot less feasible than i'd hoped. i had to go to 6 F-1As to get the stack off the ground and for now i'm trying to squeeze an E-1 in the middle for boostback but that's more dead weight to carry around and i'm not sure it can do the burn fast enough. it might end up being easier to go with the 1970 plan of doing a backflip into the atmosphere and flying the thing back to the cape, but that would probably mean going with the heavier spaceplane tankage to keep it from burning up.

Its going to happen that way. The only reason to return back to Earth is to treat some life threatning injury thats worthwhile, atleast for the early martians. Otherwise, they'd waste a year or two's worth of entire methane/oxygen production just to send people back, leaving Mars with 0 usable resources to expand. Only a politically retarded person would consider this type of plan good.

Mars will be populated by people who are going on a one way journey. There will be plenty of resources ahead of the times such that living quarters, foods, power, communications system, supplies will have already been established. Willing able bodied and capable individuals will pay to become the first Martian citizens. They will tend to their medical needs, their technological needs and their comfort. The only reason to go back would be some extreme life threatning reasons for which it would be worthwhile to waste a year worth of entire Martian resources to send back one or two people. If they're of old age, they'll die on Mars. If they have some uncurable conditions, they'll die on Mars. Resources will not be wasted, only people willing to sacrifice for Mars will go to Mars.
