First for fuck delays, I just want every company in aerospace to thrive. Even Boeing. Our best bet is to advance to the Moon and Mars asap. Although Starship will probably be the ship to carry us there

starlink pass here in 45 min, will report back with photos
>fucking clouds reee

>>11766438
>Even Boeing
No not yet, boeing will be fine with defense and aviation contacts. They need to be punished for their actions so they know to not do it again.

>>11766391
So I took up on your suggestions and drew out this very VERY rough concept.

Essentially, the satellite is in two parts. The capsule; which contains the frog(s), everything needed to keep it alive, and anything to watch it. The bus; which contains the maneuvering system, main power, cable control, and anything else. The Bus has a fly wheel to control how fast the whole craft spins. The capsule has a door to allow the frog(s) to escape once the Capsule splashes down via chutes (not pictured).

To give the best chances that the Capsule splashes down in a fresh water environment, the target landing site will be the Great Lakes and thus the species of frog chosen to live in space must be a Great Lake native. As the capsule reenters, the Bus will detach itself leaving the Capsule's batteries as the only source of power to view the decent and landing. There will be a transponder on the Capsule to allow for 4ASS specialists to track it down once it splashes down in the unlikely event that the escape door will not open.

What do you all think?

>>11766429
>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.

>>11766473

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

If you don't understand already, then the following videos, in addition to the ones already posted (here >>11752646), may help you understand:

>regarding pic related

For those of you with short attention spans who have difficulty following scientific presentations in video format, here's an illustration which can assist you in understanding that rockets indeed do not work in space. You're welcome.

>>11766467
I think that's an idea I would put actual money towards if launch costs got cheaper.

>>11766429
I want a Space Ninja gf so bad bros

>>11766467
I know it's still in the concept phase, but how will do you plan to maintain the signal/solar power/thermal characteristics while spinning?

Dont feed it.

>>11766496
>signal
That one's easy in isolation. Set the axis of rotation tangent to Earth's surface and use a parabolic antenna. Combining both that and solar/thermal configurations that don't suck is the hard part.

>>11766496
Perhaps a third module could be added which is just a dumb counter-weight at the end of the cable opposite of the Capsule and have the Bus be at the center of rotation so there could be a relatively stable point for an antenna. Not sure how the solar and thermal issues will be solved. Maybe the whole spin gravity concept can be ditched for simplicity.

>>11766514
>Maybe the whole spin gravity concept can be ditched for simplicity.
You could add a motor to the bus module and rotate the cable to provide spin gravity towards the walls of the capsule although that'd be more like pic related for the frog perspective.

Let's keep up the artemis discussion. 18 billion for SLS is absolutely unreasonable and stupid. What is the realistic soonest date for Artemis

>>11766518
>frog's reaction when twitch starts spamming "SPIN SPIN SPIN" along with every twitch emoji

>>11766524
Orion is ready now, isn't it? They could slap together an adaptor for the Falcon Heavy and launch a flyby in six months if they wanted to. Hell, if NASA human-rated the Falcon Heavy you could do a Moon Dragon flyby next week. The Gateway station's hab module won't be ready until 2023 and none of the landers are ready so that's the constraining factor now.

>>11766524
What does SLS funding have to do with Artemis? Artemis has its own funding, as well as Orion

>>11766548
They're using SLS for the bulk of artemis

>>11766528
Poor space frogs. We don't want to get arrested for animal cruelty..

>>11766530
So 2024 is actually a good date?

>>11766561
But the payloads also have their own 20 billion dollar cost on top of the SLS and another 10 billion or something sunk into Orion
Hard to understand where this money goes

>>11766571
kinda
no one really knows when they would get a lander

>>11766566
Maybe we have a frog or pepe "zero g indicator" toy in the capsule instead. Then we don't even need to pressurize it or have life support.

>>11766566
Perhaps giving the live stream chat control of the spacecraft was a bad idea. Even something like controlling music would probably just end up with them selecting "SCOTLAND FOREVER" over and over again.

>>11766571
>>11766583
also, a 2024 mission will have to skip the gateway

>>11766429

I would once again like to express my appreciation to the band Slipknot for their consummate professionalism during white room activities. I had no idea that the metal band were also a trained ground crew.

>>11766803
No it was made to bait the people mad at you because you wouldn't stop spamming anime pics in the last thread.

>>11766800
no, gateway is not firmly part of any currently planned missions

Reminder, 3 more months until Starlink beta is launched. There's 480 Starlink in orbit right now. 120 more will be added this month. Another 120-240 will be added next month. They need ~720 for complete US coverage. This will happen by early/mid august.

>>11766815
Not only would it be a pile of salt for oldspace, but I would love for Elon to have the opportunity. Jim is most likely willing to let it happen without gateway, at least for one landing. Imagine the people at boeing watching Starship touch down on the surface of the moon.

>>11766807
is SLS human rated from the get go
as in the rocket that's supposed to go up next year does not need additional tests or certification to fly manned missions?

>>11766818
Honestly if it does beat the SLS we should petition for an audit on the program. There is no excuse for such a shitty result with 18 BILLION in funding

>>11766807
>>11766823
didn't mean to reply

>>11766820
Just the thought makes my rocket stand up.

>>11766826
I’m fine if SLS flies like, 7 missions. I just want it to get over with. What I DO want is a transition from NASA. I know they are bogged down with politics- but for fucks sake I’m so sick of them choosing the same contractors who drag out projects and set us back by possibly decades. I don’t know what Jim has the authority to do, but he should kick all of old space to the curb and tell them to get their shit together. Also we’re fucked if we get a different POTUS who wants to undo everything. At that point SpaceX would be on its own

>>11766826
is there any other way mission planners could have approached this?

are the contractors really stuck to only making one specific part and can't be tasked with making something different for a completely new better rocket design?

>>11766820
I would love for the media to cover the less than 1 billion developement reusable starship costing 2 million a launch beat the 18 billion dollar single use SLS. Imagine the heat that oldspace would suffer from the public

>>11766839
>are the contractors really stuck to only making one specific part and can't be tasked with making something different for a completely new better rocket design?
SLS was designed to preserve Shuttle contractor jobs so yes. If you start updating the design you might as well cancel the entire project.

>>11766838
as long as spacex keep delivering results they'd be more or less be untouchable by a change in administration

the commercial crew program survived 2 changes in presidents because they keep showing they're the better value proposition

>>11766838
Same, i want it to set up gateway and then die. Also i don't trust biden at all for space funding, he was part of the administration that almost killed nasa.

>>11766841
>you might as well cancel the entire project.
Which they should have done from the get go.

>>11766844
Good thing he's completely senile and won't win.

>>11766839
Nope that’s the philosophy of it. With so many different people across the country, changing something drastic (or small) can’t be done unless it’s a safety measure.
SpaceX can change what the want, when they want. They test, build, test, build.
What I don’t understand is how NASA’s way of doing things isn’t streamlined. You would THINK spacex would fall in the same hole the F35 did where it just gets redesigned into oblivion, and NASA pumps out stuff rapidly because it’s already designed. But for some reason it’s the other way around

>>11766843
True but we need multiple plans for a permanent space presence so Artemis must survive. We can't lose another decade just because we shift away from the moon focus like we did in 2008

Without getting too political on the situation- Trump would only buy us four more years. After that the pendulum would swing left, at least if it follows the trend. I can’t imagine a Conservative winning again after trump.
Whatever the case, a president defunding NASA will make me riot. I’m tired of the petty politics. You can shit on trump all you want but he is faithful to spaceflight.

The toilet on the dragon is next to the nose hatch.

So to leave a captain's log. You have to squat right behind the control panel. So even if there is a curtain. Everyone else is just sitting there in their seat. Looking ik the direction of the guy turning tang into leonmande.

Why didnt they put it behind/below the seats?

>>11766862
at this point I'm confident nobody is going to get rid of Space Force and if SpaceX and BO and whoever else can live on USSF contracts and whatever anemic contracts come from the defunded NASA I wouldn't be TOO bothered about canceling Artemis. My real worry is that Russia and China are going to get upset about something and make Biden halt all beyond-LEO commercial spaceflight by forcing them to wait for a new treaty to go through the UN (of course while Russia and China catch up).

>>11766862
It honestly makes me lose hope, everyone the DNC has put forward is the type to take funding away from NASA. If you told me a decade ago that our best hope for space exploration was the Republican party I wouldn't have believed you. Now if we can figure out how to stop oldspace from wasting so much money on porkbarrel projects I'd be very happy.

>>11766868
Roscosmos is going to go under. The Russians will be selling them selves cheap to china.

>>11766868
>I wouldn't be TOO bothered about canceling Artemis
You should be, artemis is just reskinned constellation and if we lose artemis we lose another 10 years. Biden was part of the admin that shifted away from a lunar focus and it hurt us. With the ISS going away we need the moon. I have faith in spacex but i also want my tax dollars to get us on the moon permanently.

>>11766762
if you're selecting people to go to mars why would you take an electrician over an electrical engineer, mechanic over a mechanical engineer, etc.? Unless you're super desperate for labor which is unlikely

>>11766892
Welders, plumbers, construction workers electricians and mechanics are going to be needed pretty quickly because the engineering teams will be busy with more important work. Look at the artic for example. Besides musk wants regular people there, sure the first few missions will be the usual suspects but it isn't a NASA small scale mission. Its starting a colony and that means manpower

>>11766838
You're in luck with the contractors, because newspace is starting to get a lot of money and Boing! has been passed up on two big ones recently.

>>11766903
Won't everyone from any of those professions require months if not years of training in preparation for space travel + building new structures in Martian conditions? They're not going to send Jose from the construction site down the street, it's going to be qualified people whose education is much closer to that of an engineer. I imagine there will no shortage of engineers when the time comes but maybe I'm wrong

>>11766868
>make Biden halt all beyond-LEO commercial spaceflight by forcing them to wait for a new treaty to go through the UN
UN has no leverage or ability to force anyone much, less a permanent security council member, to do anything.

>>11766926
NASA under biden would look exactly like NASA under Obama. Underfunded, with no real goals and a program starting over in the hands of whomever in oldspace has the best connections.

>>11766889
>we lose another 10 years.
By the latest (2009) projections, Constellation would not have been ready before SLS was supposed to be, in a scenario which also required the deorbiting of the ISS.

>if not years of training in preparation for space travel
No, thats part of the point with Starship. They won't pick jose but there are plenty of highly skilled people in those professions anon and most will be able to work faster than engineers due to job experience. I think there will be plenty of engineers there but i don't think its and endless supply. Also do you really want engineers stuck doing normal work when there are going to be complex and demanding tasks requiring engineers and scientists?

>>11766892
>why would you take an electrician over an electrical engineer, mechanic over a mechanical engineer, etc.?

I don't know how much you have thought about this. To start with you have to want to go to Mars, a surprisingly small amount of people want to. Then you have to have the money, 200k+ for one person is not something most people have lying around. Then you have people with families, not happening. Then you have to be competent to not go apeshit in a confined space for the rest of your life. Then you have to be competent at using tools, if you haven't noticed most engineers don't know their way around a drill.

By the time you have gone through the selection process you will be left with a surprisingly small pool of candidates.

To be frank, if you want to go, have the aptitude, skills and money you will be able to go because there will be so few.

>>11766937
>Constellation would not have been ready before SLS
I'm skeptical about that, also the point is we took away the lunar focus only to put it back 11 years later. 11 years working towards that goal would result in something.

>>11766929
Yang was literally a Chinese spy.
>gun grabbing plus free drugs (opium war v2)
>weakening the President's authority to respond to nuclear attack
>open borders
>increased fusion research and space spending with no restrictions on Chinese immigration
The PRC couldn't possibly pick a better candidate, except for one that will just openly sell out to them for personal gain. Enter Biden.

>>11766958
I don’t claim to be a logistics manager, but I think the best way to do it (at least initially) is to establish something like the NOAA corps. Perhaps the NASA corps could be created depending on NASA’s involvement. You sign up as an officer and spend 2-4 required years on Mars building installations and doing science before coming back home. Later they can start establishing permanent colonies. This way you could keep it organized in teams of people like head engineers, head doctors, head scientists, etc. with teams of people under them who work as a unit to get projects done. Not to be gay or anything but this would also function like a pseudo starfleet

>>11766964
I don't think they will make workers pay 200k to go but i think they will have a hard time finding engineers ready to risk everything and ditch their high paying earth job to go to mars. You will see plenty of tradesmen jumping at the opportunity to make better money though.

>>11766964
Finding women to go is going to be a serious problem. They might well have to end up paying them.

>>11766979
I'm a tradesman, easily 95% of tradesmen are incompetent retards who I am amazed manage to not kill themselves or someone else on a regular basis. The successful and competent ones mostly all have families, very slim pickings.

>>11766978
I mean yeah initially they will have that but the plan is to scale quickly. A corps like that wouldn't work

>>11766958
Well I hope you're right. As someone who will ideally be one of those highly skilled people once colony construction gets underway, having a door into going to Mars without being rich or an engineer would be great

>>11766964
Is the 200k+ just for tourists or are you saying you'll have to pay to work on Mars too?

>>11766981
What's the point in paying someone if you are going to send them to a place with no economy?

>>11766990
Fair but you'll still see them sent

>>11766993
I guess you could get your company to sponsor you but no Spacex isn't giving out free tickets. And it would be a rare employer to sponsor you. You don't play tourist on Mars for a long time yet, it's really a one way trip.

>>11766993
Yeah it won't be the first decade but you'll be needed. Also don't listen to him, they couldn't get anyone to work there for a 200k fee

>>11767000
I have a little more than that in assets. I would sell all that shit in an eyeblink to go and build Mars, there will be enough orhers who will too. You can stay here, bye.

>>11766999
Hmm interesting. I would go even if it offered shit pay- the prospect of science and exploration fits my degree so well. But if they expected you to pay I don’t know how they would expect people to get there. Especially top tier individuals already making great salaries on Earth. But the logistics behind it make me think it will be big companies sponsoring trips- like the original European explorations :(

>>11766978
>return journey

I don't see many taking the return journey to be honest. I think people are underestimating 6 months in a tin can full of radiation. Once will be absolutely enough for most and more than a few will lose it en route.

You probably won't be coming back, you would be going to build the start of a new world. I would do it for fucking free.

>Explanation: What are those dots between Saturn's rings? Our Earth and Moon. Just over three years ago, because the Sun was temporarily blocked by the body of Saturn, the robotic Cassini spacecraft was able to look toward the inner Solar System. There, it spotted our Earth and Moon -- just pin-pricks of light lying about 1.4 billion kilometers distant. Toward the right of the featured image is Saturn's A ring, with the broad Encke Gap on the far right and the narrower Keeler Gap toward the center. On the far left is Saturn's continually changing F Ring. From this perspective, the light seen from Saturn's rings was scattered mostly forward , and so appeared backlit. After more than a decade of exploration and discovery, the Cassini spacecraft ran low on fuel in 2017 and was directed to enter Saturn's atmosphere, where it surely melted.

But what about Mars? Eventually they are going to need meat. They can grow plants, sure, but at some point they will either need to synthesize meat or bring live animals for slaughter and cooking. How will they be transported? Will they keep chicken eggs and cow embryos in stasis? I can’t imagine a starship full of live animals for 6 months they would atrophy away

Mussolini called it corporatism, in the sense of viewing society as a living thing, and Fascist Italy had the highest amount of state-owned industry outside of the USSR in Europe. The Nazis on the other hand engaged in large-scale privatization, but both forms were totalitarian nationalist ideologies which engaged in imperial conquest.

I myself use it as an umbrella term for authoritarianism, an example of which is drug laws which seek to prohibit people from making the personal choice to do certain drugs or not, and preventing private enterprise from openly engaging in the production and sale of certain drugs.

>>11767171

Neither should be illegal. People can harm themselves if they like. It’s their choice. Not yours.

>ok, I guess the FAA and NASA and every other aerospace-related agency on the planet are totalitarian fascist agencies for having restrictions on what you can and cannot do in regards to spaceflight

If it doesn’t pertain to preventing harm to others that they don’t consent to, yes.

It's not about making decisions for people, it's about creating a society that disincentivizes self-destructive behavior. At a certain point those people who are "just harming themselves" start to harm everyone around them because guess what, most people don't live in a cabin in the woods. Do you agree that we should limit the amount of dysfunction in our communities or are you gonna keep parroting the same edgy ancap lines? Surely someone interested in space exploration should be able to understand why certain nations developed into space-faring civilizations and others didn't. Hint: it wasn't because of libertarianism

Space-faring civilizations don’t exist, but it looks like the first one will be launched on private launch vehicles for private reasons. No, wasting time in LEO isn’t space-faring.

>>11767364

No.

>>11767364
The only way to save the shuttle would be to give it a big first stage that lands and use a low maintenance fuel cycle, then the shuttle becomes the upper stage on top of that and burns delta v with standardised heat tiles and then lands on a pad. That's how you fix it.

Is this from the alternative timeline where it did maiden flight ahead schedule and on budget?

>>11767395
Lunar science is super valuable. Yes the apollo program was meant for the US to flex it’s dick over the soviet union, but so much was gained from the rocks that were collected. The moon serves as a holy grail for geologists

>>11767409
Nah in that timeline it launched in 2040 because they needed another two decades to paint the foam.

>>11767411
>The moon serves as a holy grail for geologists

Yeah

Except

There's no fucking geologists there.

>>11767413
Well but the geology instead it's all over that place.

>>11767413
What are you talking about? We trained the apollo astronauts in geology and sent a geologist there. We brought back hundreds of pounds of rocks and did a bunch of petrology here on Earth with the samples. Yeah apollo ended up being defunded because lack of public interest, but we’re going back and we’re sending geologists there again

>>11767413
There doesn't need to be. Studying the composition of lunar regolith and photos of it landscapes can provide vast amounts of knowledge.

>>11767411
>Lunar science is super valuable

Yeah, for establishing moon colonies and mines, which we haven’t done in the intervening half-century since

> The moon serves as a holy grail for geologists

Oh yeah there’s lots of them up there....
I can’t wait until NASA spends a gorillion dollars to have people amble about up there again, pick up some rocks, then return. Don’t get me wrong; it’s cool to see, would be a positive image, which I think normies may need these days, and I’ll certainly stick the kids in front of the TV to watch it happen, but what does it achieve materially?
I want colonization, not tourism.
Space is to conquered, exploited, and inhabited. Not merely observed and visited.

>>11767423
We still send surveyors to evaluate potential mineral deposits while satellites exist.

>Polar satellite
Don't know much about Indian rockets but it probably helps that it's mostly solids with some hypergolics. No cryo or anything fancy
>Expendable F9
Still benefits from the long period of iterative development which was made possible by the data gathered through reusability. Good corporate ethos, like focus on vertical integration (taking as much production as possible in house, not making the rocket standing up jej) and accepting taking tradeoffs for expense over autistically chasing maximal performance.

>>11766579

>>11767833
Yes we could

>>11767840
Theoretical based on calculations I believe, but does sound a bit high.
Obviously in expendable mode.

>>11767840
From SpaceX

>>11767840
"Upto" They won't push the limit if they don't have to.

>>11767840

>>11767833
For Falcon 9, propellant mass is ~500 t, of which ~150 t is RP-1. Let say that you're launching 7 persons per launch, ie a billion launches to get everyone to orbit, this means you need ~1.5e11 t of RP-1.
For comparison, world total kerosene (from which RP-1 is derived) consumption is around 190 million liters per day, or 1.5e5 t per day.
So you'll need the 1 000 000 times the daily production of kerosene (which isn't RP-1) just for the fuel part of launching 7 billions people to orbit.
Also for comparison, the consumption of crude oil is around 1.34e7 m^3 per day, ~1.1e7 t per day.
If you're magically able to change all crude oil to RP-1, you need to consume all the oil production for 40 years.

>>11767939
Why are you looking at specs for the Full Thrust? Block 5 is what's flying these days. FT = Full Thrust.

I'd suggest contracting Elon himself and having a Frog Dragon. Basically a Cargo Dragon with a self-sustaining habitat for various frogs to live in. The trunk could have an extendable ring module that can be attached to the ISS or something for the frogs to have artificial gravity.
>>11767364
What would've saved the shuttle is sacrificing a large amount of that cargo space for an integrated fuel tank and replacing the SRBs with reusable rockets like the Falcon 9 or something. Also, the RS-25s should've been replace with methane-fed engines.
>>11767802
Poos are caucasians too
just overcooked and overproduced
>>11767841
Especially the literal kind.

>>11767960
Starships carrying 100 people work out a lot better. Methane (nat gas, although you do have to isolate as nat gas isn't 100% methane) production is high, and the fuel ratio is oxidizer rich (like 20% methane by weight as far as I can tell). 5 years of just US production could do it, ish.

Biden wouldn’t fuck up anything at NASA too badly, and he might even help a moonshoot along if elected

>>11768069
Biden has had a 50-year political career and has voted on exactly 0 substantial space-related legislation:
https://medium.com/swlh/joe-biden-space-policy-enigma-57fd15b82472
Worse than being openly anti-NASA, he just has no opinion whatsoever and almost certainly will use defunding NASA or hamstringing American commercial spaceflight as a bargaining chip in another piece of legislation or international negotiation because he clearly just does not care

>>11768069
Biden isn't getting into office even if he wins. He's off to the nursing home and his VP takes office if that happens. He's not eligible for office with his condition.

>>11768069
>>11768097
>>11768101


Biden, if he ever gets elected, doubt it, can not mess with the current "return to the moon" program at least.
With the sole reason being NASA has set this mission up as having woman being the first one to return to mars this time, no politician in the current political climate will risk being the guy who stoped that mission.

>>11768107
Of course they fucking can and they will mess with anything that can be perceived with as a posthumous win as the Trump administration. I don't think you realize just how petty politicians are and just how little they give a shit about space exploration. They'll just let it run on the back burner for the first 3 of their 4 years of the first term, then they'll announce that it's taking too long and has too many tax dollars that "could have been spent on more important programs for the local communities" or some bullshit like that, then they'll axe it. Just like Constellation.

>>11768115

>>11768178
no, I'm just trying to point out how easy it would be, politically, to crush American spaceflight aspirations and push us back into an age of "spaceflight is only good if it's for climate research" and yet another Mars rover and no moon base and yet another ISS extension... When Musk talks about our window to become multi-planetary being short, this is what he's talking about. Political will can easily hold back all of manned spaceflight if it doesn't hold it in high regard and is willing to give it up or cut it out for little-to-nothing in return.

>>11768193

Settling the moon is not like desalinating the ocean. Either way, it's not "which interpretation is right" it's "can it be interpreted this way" and if so, there's nothing stopping the president from forcing this viewpoint.

Both are use of resources common to all humanity. The Outer Space Treaty literally allows settlement and utilization of lunar resources. It's not there to limit the exploration and utilization of resources in space, rather to prevent the politicization and militarization of space.

>>11768186
>When Musk talks about our window to become multi-planetary being short, this is what he's talking about.
No, he's talking about far more pervasive social collapse. NASA is interested in pilot projects and r&d, playing with NASA missions/funding can delay or speed up progress in some areas but it is not the long term driver.

>>11768230
Yeah to be fair NASA is the king of wasting money. They don’t even have a plan for a mars Architecture, just some vague stuff about “oh yeah there’s a Gateway” and “yeah the uh Transport”. At the same time they’re not even willing to spend just a few million to bend some metal even. It’s so weird. Literally a wooden mockup of the Deep Space Transport or at least select a specific design of smarts Mars lander you fucking retards instead of changing it ever four months.

>>11768204
>Elon’s done and said a lot of things that would piss off someone like Biden.

>At the same time they’re not even willing to spend just a few million to bend some metal even. It’s so weird.

I'd imagine the life support of any well made colony or ship will be a triple redundant system which can if possible perform it's most basic functions without even requiring power. Idunno, somehow use the differential temperature between waste heat and the supercold vacuum on the dark side of the station to circulate air in an emergency. Passive CO2 scoops located so that the natural air currents and station spin force enough stale air into them to keep levels from reaching the hazardous line. You'd want to build as many systems as possible like the passive safeties of an atomic reactor, so that they can be tripped by changes in the environment without the need for human or even computer intervention.

Nah, quadruple redundant.

>>11768383
>All the pol nonsense shitting up the place still remains though.
Wrong, the J*nny has deleted a ton of political posts in the last few threads and locked the second last thread because of it. He also deletes anything that is against anime shitposting and got the mods to give out month long bans but let's not get into that. Beyond those two things, there doesn't seem to be any rhyme or reason to what else gets deleted, maybe it's just anything that he disagrees with.

J*nnies need to get spaced.

>>11768453
These are nice ideas, but realistically we're decades at least away from having tech that can do these kinds of jobs with such low risk. I wonder about a mars colony considering how much maintenance work the ISS needs done constantly

>>11768416
In a large cylinder it'd take weeks for the oxygen to deplete. Same for heat, especially if there's a lot of water.

>>11768484
The problem tends to be buildup of CO2, not depletion of oxygen. Any large ship or station will need a substantially upscaled regenerative CO2 scrubber system, ideally with at least two redundant backups and a mode of minimum, nearly unpowered and unregulated function in case of extreme emergency.

>Is Biden gonna win? The polls are scaring me guys.
The polls are fake as shit just like 2016, with low n and ridiculously bad sample composition. Look at primary turnout, look at Biden's endless parade of senior moments, look at rally attendance before corona stopped them. Trump will win based on those.

>>11768383
>>11768460
yeah we just need to ban anime until the shitposting calms down. Also Talking about the quagmire that is SLS is very relevant to /sfg/, we shouldn't ban everything just because it is political. Look at all the good replies to deleted comments.

>>11768204
>Polls.
This Anon >>11768497 gets it, their methodology is absolute fucking garbage because they don't give a fuck about representing reality at all anymore. Pretty much every political """poll""" I see these days is either trying to gaslight and blackpill it's target audience or artificially inflate the confidence of it's target audience. Zero accuracy or relevance, 100% pure manipulative propaganda.

Ignore outright any poll that isn't a very well put together aggregate.

Where is my horse

>>11768663
I keep reading people saying that the first satellites won't have much capacity, we have to wait for the next generation.

Lads I have a really dumb-ass question but I'm genuinely curious:
How can satellites take high res images of the Earth's surface when they're moving so fast with respect to the ground?

>>11768398
>Still works though.
You sure about that?
In order to have sea level pressure do you understand how tall the walls should be?

>>11768677
Light moves faster

>>11768677
The answer is that Earth is large as fuck, and satellites (even in low earth orbit) are very far up.
Imagine this... you’re on a road trip going really really fast in your car, like 100mph. Obviously the buildings right next to you will be moving very quickly. But the further away things are, the slower they appear to move. Because satellites are so far away, the Earth below them appears to move slowly due to its distance and unfathomably large size. This results on plenty of time to use a camera to snap a high res zoomed in photo

>>11768634
Any videos of this? I have only seen the camera centered on Vice President Pence, while this was happening.

>>11768677
For the same reason that a mountain in the distance hardly seems to move even when you're driving at 100 km/h

what are they doing up there?

>>11768903
Nothing too important, since it was mainly a test mission they weren't carrying any important cargo and their short stay means they will be mostly just supporting whatever the other astronauts are doing

Japan is literally dying and their economy is shrinking.

>>11769005
Call me crazy but japan will be the first nation to prove that you can survive with endless economical growth and expanding the population.
We are up for a second industrial evolution thanks to AI software, from replacing truck drivers to replacing low level white collar workers.
And again, japan has much better birth rates then western nations.
And they gave a pretty decent space program.

I now it's a old meme, but china is a bubble that is going to explode one day.
Just look at how some trade wars between Trump and Xi made the chinese desperate in the whole rare earth mineral situation.

>>11769028
China is also dying, but that’s expected from degenerate communist societies.

>>11769028
China bubble story has been spoken about since before 90% on on /g/ were born. I'm serious. China bubble/collapse story is just a feel good story, there's nothing to it.

>>11769023
China won't exist in the form that we know by the end of the decade.

>>11769034
Lets hope for better. I'd rather not a militaristic China but if they suddenly decide to go democratic and treat their own citizens with human rights/dignity, I'm all for it.

>>11769033
people said the same thing about america after the revolution happened, that it would eventually pop.
It just took 250 years, is all

>>11769033
That's because the CCP has been keeping the booth against the necks of the people all this time, at some point something will happen that will give slack.
Then your going to see some crazy shit, hell, even the chinese fear it because in the past everytime a civial war happend millions died in china's history.

>>11769039
best case scenario is a balkanized china.

>>11769033
anon, the entire history of China is "things go to shit, millions dead"

>>11769044
>balkanized china
It's gonna be this. The rest of the world wants to keep parts like Shenzhen around and functional, but China as a monolithic concept and state will fall apart in the near future.

>>11769044
>at some point something will happen that will give slack
probably not going to happen while Xi is alive. Chinese government is fairly free of corruption at this point, but once he dies and there's a power vacuum it's all over, as has been the case in many communist states before.

>>11769055

wait until they finish the next high bay. It's twice as deep (so a square instead of a rectangle) and taller than the existing one for stacking Super Heavy

You think real estate in and around Brownsville will significantly jump in the coming decades because of SpaceX? I imagine it’ll get a lot of activity once Boca becomes the staging point for Martian voyages

That's not a swamp, we don't have swamps in South Texas. Those are barrier islands. They protect from things like hurricanes, high waves, high tides, and other waterborne disasters from the ocean. Lots of countries build artificial ones to protect cities and harbors, pic related.

Does anyone know the exact dimensions of the Starship's cargo bay?

I need this because I'm working on an OC project which is basically a concept for a replacement space station for the ISS. The main feature being a rotating torus assembly serving as crew quarters. The torus must be divided into modular segments which are prefabricated on Earth and assembled in orbit. Consequently, each segment must fit in the Starship's cargo bay.

Another issue I'm trying to work out is the main bearings for the torus assembly, so that only the torus part of the station rotates while the rest (ie. docking areas, microgravity labratories, solar panel arrays, etc) remain stationary. It would need to produce extremely little friction or else the torus must use propellant continuously to keep it spinning at its target speed.

>>11769421

It’s in here just scroll

>>11769453
You post this often enough that I think you actually believe it makes sense, which is baffling

>>11769453
No, no, no: negative mass ceiling plates.

>>11769457
The neutrons would be dense enough to generate a noticeable gravitational attraction, so you could theoretically create floor plates that have appreciable gravity from their density
The real issue is how to synthesize that much superdense neutron material and logistics of assembling a floor plate like that

>>11769472
>synthesize netronium
impossible
>keeping it stable
imaginary

>>11769472
There are only two ways to get effective gravity, acceleration and actual gravity. Your solution is just actual gravity, which means it would require the same amount of mass as carting around an entire planet. Having more dense matter doesn't change the way gravity works. Neutron matter isn't stable outside of a neutron star, anyway.
