More testing of SN8 right now. They'll probably go for another cryo test after last night's leak, which was fixed earlier today.

Why are they going through so many SN? Why building new ones instead of keeping and modifying those who pass all the tests?

>U.S. Transportation Command looking at Starship for rapid cargo delivery

Found some predictions and talk about space travel from my grandpas school book from 1959
Some of the ideas here are really cool

"There are many plans for permanent artificial moons. Here's one, a cylinder which is planned to be 300 meters in diameter and 900 meters in length, with a 450 meter diameter wheel at the end. The spinning motion would cause an artificial form of gravity, which would make the staff onboard more comfortable and more like home. This space station could hold 5000 people. Although Van Allen radiation has thrown the possibility of these manned stations into question"

>>12206154
ASS TO ASS

Another cryo test happening right now.

>>12206256
That's not how you spell "RESLUTS", anon.

>>12206277
These are really fucking close to current starship designs, kinda cool when you think about it

>>12206285
Resluts sounds like a second hand store for hookers

this guy is the new commander for the starliner test flight

>>12206297
Should have a female PoC instead.

>>12206288
but they couldn't correctly predict ass-to-ass docking.

why's that one rocketship shedding its wings and tail?

The cargo delivery thing makes me realize that it's very possible that Guam would be one of the places to get a Starship launch platform. Diego Garcia? Idk maybe.

I'm so hyped up for SN8. If it sticks the landing then it's the Apollo 4 moment when you know all this shit is actually going to work. Walter Cronkite got giddy on national tv because he knew then and there we were going to the moon.

>>12206288
These predictions were pretty close as well. Although the later ones never came into fruition.

Artificial moons 1957-1962
Artificial moons orbit the earth gathering data and scientific experiments. A larger, permanent station could be designed, if the recent documentation of radiation will seem safe.

Manned flights 1959-1962
The first phase in mans space travel will be high altitude rocket planes, which can reach an altitude above 150 km. but will stay only for a short period. On these flight we will see a human's relation with weightlessness and other extras of space exploration. Currently in testing is the Lockheed X-15 in the USA

Unmanned probing station to the moon 1961-1963
In about 3 years it could be possible to send an automatic radio controlled expedition to the moon to measure things such as visuals, temperatures, radiation, magnetic fields, gravity etc.

Manned lunar flyby 1965
Here's where American and Russian estimations diverge significantly. Americans are careful and estimate us to be this far in about 5 years, while Russians are talking about a smaller timespan, even possible by now. Americans believe it to be pointless to send a man onboard, since a robot can do the same job - maybe even better. The only reason to send a man onboard would be the "sense of adventure"

Man on the surface of the moon 1970
A careful estimate says that man can land on the moon only in the year 1970 or maybe a few years later. Then we might figure out many of the mysteries surrounding the moon; is it a part of earth that came off, what is in the lunar craters? etc.

Venus and Mars 1980
No time estimations of interplanetary travel have been made, but it can be said, that these travels may begin in about 10 years after the first manned lunar landing. Then it would be possible to utilize all the technological advancements for these travels. Then the only limiting factor would be time and... money.

Kind of chilling how right they got it.

Someone help me understand the "Soyuz 2" usage in the file name. Is this a test article for a post-MS version?

The original Soyuz 2 was a thing that Georgy Beregovoy failed to dock with back in the late 60s, and there wat at least on other phantom "Soyuz 2" which was scrubbed around the same period, possibly related to the Komarov death or otherwise.

If Earth was a moon of Jupiter, how big would Jupiter appear in the sky?

>>12206389
There he is!

"Most likely the most recognized expert in space exploration is the German-born, now living in the USA, Wernher von Braun. He's really been the "miracle child of rocketry". He became the spokesman of the German board of rocketry and the head of German rocket research all in the same year. Under his control of the Peenemünde research center, the infamous V2 missile was created, which rose to an altitude of around 100 km and reached a top speed of 5000 km/h.
von Braun was only ever interested in space flight. Hitler got a word if this and had the young scientist imprisoned, and facing the possibility of excecution. He was saved when it was concluded that the V2 project could not continue without him. At the end of the war he gathered a group of his assistants and escaped from Peenemünde from the advancing Russians to the American side. In 1946 he became an American citizen, and today runs the rocketry experiments for the US army. While designing military equipment his only real endgoal has been space. In this picture he is seen showing one of his designs for a lunar spaceship."

>>12206394
Did they fix the leak?

>>12206433
baste

>>12206439
It is my understanding that they potentially did and this test is to verify it worked

>>12206417
Kerosene is a bunch of different hydrocarbons, Syntin is 4 flavors of the same molecule.

>>12206429

On a scale of 1-10, Jupiter would appear terrifying/10.

>>12206417
it's awesome, the isp of propane with the density of rp1. the only knock on it is price per kg. also superior for shuttle oms fuel because you don't have to deal with the pain of cleaning out toxic fuel tanks after each flight.

>>12206433
>Hitler got a word if this and had the young scientist imprisoned, and facing the possibility of excecution
Pretty sure even Von Braun didn't go as far as to claim he was ever arrested and facing execution. It's a good cover, though, I suppose.

>>12206451
Some cool predictions that came true like common solar power and video calls

>>12206447
Let's say 1,500,000 km or thereabouts. So somewhere between Ganymede and Callisto.

>>12206470
Unlikely, but still a possibility, because if he had made the V2 only with spaceflight in mind, one could jump to him just pissing away german warfunds, or worse yet, possibly profiting from the V2 which would be profiting from war, which was one of the most heinous crimes in Nazi-Germany's eyes

>>12206470
He was arrested by the SS as part of a ploy by Himmler to take over the V2 program. One of their charges against him was that he was more interested in spaceflight than political loyalty (a false charge, he was an enthusiastic Hitler supporter). The death sentence thing I haven't heard of.

>>12206496
Buran was a soviet copy, and the soviets understandably assumed that the "reusability" was just a ruse by the americans to hide the purpose of satellite jacking. They wanted to one up the US by making a less shitty orbiter, only to find that Nixon-era NASA was just that stupid.

>>12206492
it's a soyuz-2.1a on the pad
also called soyuz ST-A

>>12206503
It likely wouldn't have, No SRBs to fail and there was no foam on the energia to fall off and smash a hole in the heat shield. Not that it would've done so anyway, considering the soviets reasonably bolted the plates on, unlike their nasa counterparts who thought gluing them on would suffice.

Space flight is an escapist REALITY

>Postflight investigation found that the failure was caused by an unforeseen design flaw in the new Soyuz 2.1a Blok I stage — the propellant tanks were shaped differently than in the older Soyuz-U booster, which ended up producing resonant vibration when attached to the Progress spacecraft. The normal flight program would vent out the nitrogen pressure gas from the Blok I tanks following spacecraft separation, but engine cutoff produced a hammer effect that sent a shock wave through the stack, rupturing the propellant tanks and blasting the Progress into a much higher than planned orbit, while also leaving it in an uncontrollable spin and having suffered structural damage from being struck by flying booster debris.[22]

Here's some of the most interesting speculations about Mars

"Can there be flora on Mars? Yes, says a recent study. It is known, that Mars has a very thin atmosphere, equivalent to Earth's atmosphere at 13 km. It's consistency is slightly different to ours, since oxygen is almost completely missing and the air is made of carbon dioxide and nitrogen. This does not rule out the possibility of plant life existing, since they require carbon dioxide and emit oxygen. Animals and humans instead require oxygen, so it's improbable for mars to have them, unless humans there have become so advanced to be able to chemically extract oxygen from other chemicals.

Latest studies have even shown, that light refracts from Mars is similar to lichen and moss. This would prove, that at least plant life would be found. Science usually doesn't guess, but uses facts and studies to draw their conclusions. But from Mars there have been many guesses, which seem very plausible.

It's been suggested that Mars could be a dying star, drawing it's last breath. Oxygen would be depleted and it has been suggested that the red color of Mars would be the result of oxygen bonding with the iron at the core, and forming rust, and the atmosphere being so thin, it could not stop the large changes in temperature.

If there are any humans on Mars, they would have to live in tightly closed off areas with oxygen heat. Scientist also say, that it is very possible that the life on the planet may be completely alien to us. For example, it it completely possible that animals there breath carbon dioxide instead of oxygen.

So when we go to Mars, we can expect almost anything, possibly we'll find a deserted, dead planet, where days are hot and nights freezing cold, and where only in the summer on the equator we may find moss growing. But we may find at the bottom of a ravine the remains of great ruins, which prove the existence of a highly developed civilization, which once lived on this planet.

>It's been suggested that Mars could be a dying star, drawing it's last breath
Man, that would've been really cool.

For the same reason that there are still wolves yet dogs exist, or the same reason there are still mammals that lay eggs, or the same reason that there are still fish in the oceans even though some adapted to live on land. That reason is of course the divine creator.

Are they planning on insulating the tankage at all, or is the ice not considered to be an issue?

>>12206679
well falcon 9 doesn't have any so it's unlikely

>>12206679
Liquid nitrogen is much colder than liquid methane and oxygen. Its basically a non-issue.

Why is Mary standing there? Can't they operate the camera remotely?

>>12206679
when fueled with methane there won't be any ice forming on the surface, so no

>>12206679
I'm just wondering if it will ever get this cold before a launch once they pump it full of methane and oxygen. Will white starships be a sight? Or are they intentionally making it cold as FUCK to push all the systems to the limit

>>12206650
I don't understand the reusable crew meme.

>>12206687
So no white frosty in real starship?
Imagine frost hitting the tiles.

>>12206691
They're using LN2 which is similar to LOX and LCH4 in temperature, so yes it'll get that frosty. I suspect the TPS tiles will frost less if at all.

>>12206693
There shouldn't be any really extreme frost, no.

>>12206511

There's a real answer, thank you. Not to be a cunt but it was warranted.

>>12206698
Yeah I doubt they will freeze. It'll be pretty interesting to see. And to the anons asking about ice safety, I doubt it's an issue at all. Vertically stacked... plus the overall design of SS allows it to take a hit without failing. I'm no expert but I'm pretty sure starship could survive a reentry should one or more of its heathex tiles gets damaged. It's steel, not aluminum

>>12206698
Methane freezes at 91 kelvin. Even sub-cooled, it still needs to be 92 kelvin or warmer. Oxygen, meanwhile, can be as cold as 56 kelvin without freezing. Nitrogen liquefies at 77 kelvin.

SpaceX doesn't have a slogan. If you were in charge of making one, what would you choose?

>>12207300
FUCK URF

I don't know how engines work but aren't the helium and nitrogen and work fluid in this diagram going to need refilled on Earth between flights? Would this be a problem for moonship?

>>12207307
Probably used in such small amounts theres no need to refuel on a flight.

>>12207307
Nitrogen is easy, but helium would be a problem if it were reliant. A cursory search suggests that Elon wants to eliminate helium and also that argon (which is also easy) would be a suitable replacement.

If we had the engines for it and some good programmers, could we build our own starship clone or something like it, since they’re mostly tank and plumbing?
Hell, if we could build a lightweight small fission reactor and cool it in vacuum, we could build the first long range armed exploration spacecraft

>>12207307
this is not official. It is possible to bootstrap yourself from tank pressure CH4/LoX

>>12207365
They're definitely doing autogenous pressurization, that's not what this is representing

>>12206630
link?

>>12206188
Because the eventual plan is for SpaceX to have as many Starships as Southwest has 737s which means that ramping up their production capacity to the point where they're making a new SN every week is every bit as much of a priority for them as the iterative improvements being made to the Starship prototypes themselves, which means that rather than iteratively modifying the existing prototypes, they just add the changes to the next ones coming down the assembly line. It doesn't hurt that stainless steel is so easily recyclable and as such is so valuable as scrap as well.

If they were only planning to build as many Starships as they have F9 cores then yeah, you'd absolutely see them adding aero to SN5 and SN6 and prepping them for the suborbital test flights that they're absolutely capable of.

"It works in Kerbal Space Program"

>>12207391
cheeky

>>12207398
Yes but only when the X-2 deep space shuttle becomes operational

>>12207398
How much of that is small fry/hobbyist shit? How much is shuffling around a few hundred miles? The closest equivalent to something like a starship launch would be a big intercontinental flight, so a small subset of that. But still obviously no, and in addition I think it would be more logistically sensible just to increase rocket size than cadence at some point.

>>12207398
I think you might see a couple dozen a day, Elon wants Starship to fly thrice a day once the design is finalized, if he built ten launchpads for it to fly from then he might be able to squeeze out 30 launches a day.
Nothing ULA or Blue has is even remotely close to that kind of cadence, I don't there's even been a quote from Blue about how often New Glenn or New Armstrong can launch at all, and Vulcan from ULA is following a more conventional design that precludes fast turnaround.
Boing doesn't even have a plan for a reusable rocket at all, SLS will be lucky to have a launch cadence of once per year.

Nautilus but with a Starship and Sierra Nevada inflatable habs. Talk about fucking cool. It could function as a HUGE station (be it around Earth, Moon, Mars, etc.) or as a ship to take you to Mars or do a Venus flyby. Basically just a starship with extra space in the back thanks to your inflatihabs.

>>12207476
You would need some killer engines to get that thing to move. And I know starship is capable of docking from the ass because of refueling but idk how crew would transfer.
Regardless, you would have a fuckhuge amount of room. Starship alone is more than the ISS. Adding SNC habs would make it unbelievably large lmao

>>12207476
Whats the point of the circular bit?

>>12207465
Musk hopes for once a week launch next year (launching upwards of ~50 next year). We were very close to once every two week this year before the whole coronovirus/weather delays. I think in 2022 or 2023, they'll be very close to one a day launch.

>>12207507
Rotating hab for artificial gravity. Not a bad idea actually.
https://youtu.be/1wJQ5UrAsIY?t=6

>>12207511
Yeah but wouldn't you either need to rotate it really fast or make it way bigger in order to get an appreciable amount of artificial gravity?

when do you see the 15km hop happening bros?

>>12207517
2-3 weeks

The question now is whether Musk will do 15 km hop before or after his updated Starship presentation. I hope its before the presentation just to show a flown Starship as a real benchmark/progress measurin stick.

Did we get any news on the SN8 leak?

>>12207517
6-8 weeks. I doubt they will do it before the presentation.

>>12207527
In all likelihood he will push his team to the best of their abilities to get it done before then. He'll want to go into that presentation with every ace up his sleeve he can get
>>12207516
As far as I know a huge study was done for Nautilus X (with existing technology) and it was deemed possible. You can get it up to rotational speed.

>>12207529
Was fixed yesterday and tested this early morning. And it looked like a successful test (but then so did the previous night).

>>12207508

>>12207558
They'll have to put the raptor (~2 day), static fire (~2-3 day), then put nosecone(~2 day) on. Then fly. It will be at least 2 weeks but could extend to 3 weeks.

>Based in Santa Clara, California, the company’s business centers around its Vigoride transfer vehicle, which helps deliver satellites from a rocket to a specific orbit. Vigoride consists of a frame, an engine, solar panels, avionics and a set of satellite deployers and is especially designed for satellites that hitch a ride on large rockets, an increasingly popular industry practice called ridesharing.

I mean they'll be doing DragonXL which is quite a large tug which is supposed to carry up to five tons around Lunar Orbit to resupply LOPG, I suppose it's possible you could just take only the propulsion and power element of that, put an adapter on it and use it in LEO for larger satellites as well, but I just don't think there's much of a need. After all, SpaceXs own sats don't need a transfer vehicle, and those are the most common sat they launch.

>>12207822
lolwut, pretty much all of oldspace has access to more resources they just use them inefficiently

>>12207400
That's like the opposite of sunk cost fallacy lmao
Your same argument could be said for giant aircraft that can carry ten thousand people, "Nah we'll never have a hundred thousand daily flights because it's more efficient to just fly mega-planes". Like, dude, there are more facets to what makes something an economically viable option than just straight up efficiency, or even effectiveness. Orbital rings are a planetary scale megaproject and even if we figured out all the problems with the technology and had all the funding and industrial production necessary to make it happen, it would still be an impossible political barrier to attempt to get that project running.
A hundred thousand Starships a day would probably be overkill for anything less than mass-exodus or mass-diaspora type movement into space, but it'd be a shitload cheaper and easier to just scale up the production rate of Starships and the number of launch facilities to allow that to happen. Say four launches a day, that's 25,000 pads worldwide. More than ten million tons of cargo to orbit per day, ~3.6 gigatons of cargo to orbit per year. This is basically orbital ring launch territory anyway. Would an orbital ring transport system with elevators to climb to 250 km altitude and electromagnetic tracks to accelerate along up to orbital speed be less expensive per kilogram payload? Probably. Would it be less expensive to build than a fleet of Starship launch complexes capable of 100,000 launches per day? I doubt it. A million Starships tip to tail would encircle the globe a bit more than once, but most of Starship is just steel tanks. An orbital ring needs to be made of superconducting magnets and the active control systems that prevent wave instability propagation from ripping it apart, plus the elevator tethers that let you climb up to the ring plus the hardware on the ring that actually accelerates you to orbit.

>>12207829
another bit:

Las especificaciones de Roscosmos obligan a que el coste de lanzamiento del Amur no salga por más de 22 millones de dólares en la versión reutilizable sin etapa superior. El coste del lanzamiento con reutilización de la primera etapa y con empleo de una etapa superior saldría por un máximo de 30 millones, mientras que un lanzamiento sin reutilización y con etapa superior no puede costar más de 35 millones.

Translation:

Roscosmos's specifications require that the cost of launch of the Amur be no more than 22 million dollars in the reusable version without upper stage. The launch cost with reuse of the first stage, and with the usage of an upper stage should cost a maximum of 30 million dollars, while launching without reuse and with an upper stage should not cost more than 35 million dollars.

Those are some nice prices but who knows if the russkies will be able to achieve it in the time necessary. The clock is ticking.

>Never said the gender.

>>12207660
>The fuck is a water plasma engine?
Use electricity to heat propellant and generate thrust. It's not fundamentally new tech, it's just one of the options that usually gets passed over for better options. All electric thrusters are very low thrust, so it usually makes sense to just go for the most efficient option because you're eating a shitload of spiral trajectory losses anyway. Therefore ion drives have become top dog because they're simple and they get the best performance. Some vehicles have used resistojets to squeeze more performance out of monopropellants I think (they use electricity to spark an arc through a chamber full of decomposing hydrazine; the hydrazine gets hot by decomposition anyway and the arc boosts that peak temperature which increases exhaust velocity and therefore thrust without adding to mass flow rate. Better than monoprop alone but nothing revolutionarily good).

>>12207719
>presumably the same stuff as F9 but it'd be really hard to refill in orbit.
Raptor doesn't use open-loop hydraulics, it has a low pressure return line that feeds back into the fluid reservoir. There's no loss so there's nothing to refill.

>>12207844
rough math here but 100,000 starships per day would cost something on the order of $43 trillion per year in methane alone. yes, i'm pretty sure an orbital ring would be cheaper than that.

>>12207871
Probably not cheaper to build, honestly. Look at fucking ITER, a project microscopic by comparison, taking decades and billions to complete. An actual orbital ring launch system on Earth would probably cost over $1 quadrillion.
If you want to consider the "maybe we'll have automation do it for us" angle, then the original argument against Starship goes away anyway, because with automation all products become extremely cheap and you can afford to put a 1000x1000 km solar array at the equator on the Pacific ocean that uses electrolysis and carbonic acid capture to generate methane for effectively zero cost because there's hardly any human labor involved.

>2040, both Moon and Mars are at the point at which they can accept a large influx of people, in fact the rate at which Mars can accept new colonists is greater than the rate at which SpaceX can throw people at them.

I've been wondering about what they'll do about all those extra Starships on Mars. I mean, they're going to send dozens over, but only one or two per synod will return. Sure, some of them may get used as makeshift habs, but it's going to be a pain having to climb past the tanks all the time.
But think about it. Starship is fully SSTO when launched from Mars, and with enough fuel left to reach Earth. Imagine if you then refilled it with tankers. Where could Starship go from Mars orbit with a FULL fuel tank? Hmm, how about... Ceres? Vesta?
And I think Musk is smart enough to have thought of this already.

>2045, the first very large orbit-only spacecraft are under construction at the Earth-Moon L2 station. These are big enough to produce 1g via spin gravity, and while they rely on chemical propulsion for some maneuvering, they also have plasma magnet sails that let them use the solar wind to go from sitting at L2 to coasting on their intercept trajectory without using a drop of propellants. These motherships carry large amounts of cargo as well as several Starship (or whatever it has evolved into at this point) vehicles to use as surface-to-orbit shuttles. Since these ships are so large they can afford to be nuclear powered without killing their mass fractions, and they need nuclear power anyway for going far from the Sun.
>2050, the next giant leap occurs when these huge spacecraft perform the first manned missions to the outer planets, mostly through plasma magnet sail propulsion, but at this point we almost certainly have good fusion propulsion options too. The Moon and Mars are becoming much more populated and developed. Phobos is an industrial outpost that produces massive habitats and ship hulls. The asteroid belt is being explored and effectively colonized by people living in large habitat ships.
>2060, there are people living in habitats orbiting Jupiter, Saturn, and Neptune with early ground settlements starting up. The Uranus exploration flotilla has just arrived, having taken the slowest transfer velocity due to the distance and the weaker plasma magnet sail braking option (Neptune is so far form the Sun that its magnetosphere is really big, and thus gives you the distance necessary to slow down from a higher speed transfer without needing propellant). There has been manned exploration of Mercury, and there are plans to build aboveground colonies at both poles, with many more habitat complexes spread across the planet deeper underground where the intense heat from the Sun has no effect.

>The contract was won by Alliant Techsystems, and featured new motors with composite cases rather than the steel cases of the earlier United Technologies Chemical Systems Division (CSD) solid motors. The first segment came off the production line and was found to be delaminating, a serious problem that had to be corrected and caused some delay. Then, when the first motor was being stacked for a ground test firing at Edwards Air Force Base on September 7, 1990, the crane collapsed and the segment fell and ignited on impact, resulting in more delay. When the first motor was finally stacked and fired, it exploded; redesign was required and that caused more delay. Additional CSD steel cased motors had to be procured. Then the motors for two launches that were already stacked on the pads at Cape Canaveral were found to have signs of corrosion and had to be de-stacked.

Finally, the companies got together and agreed to kiss and make up if the Air Force would cough up another $250 million.

It's not about going as far as possible, it's about being as effective as possible wherever you're going. With that in mind, I'd say the first step for space colonization beyond Mars colonization would be to do Phobos colonization, or at least Phobos industrialization. Figuring that out gives you all the technology you need to colonize or mine any asteroid, plus experience building large structures in zero G, and alongside the lessons learned it also actually gives you an in-orbit mining and production operation that you can use to build large habitat ships.
After you get Phobos turned into a shipyard, it becomes really easy to imagine large scale asteroid colonization. Even if your big habitat ships only have 3km/s of delta V, that's enough to go from Phobos orbit to the middle asteroid belt with about 1000 m/s leftover, which easily lets you check out a dozen asteroids or more in order to find one with a decent water ice content, at which point you can park for a while as you ISRU that water into propellants and refill your delta V budget to 3km/s again, which lets you go to Ceres no matter where you're starting from in the belt. Once at Ceres you probably are going to hang around in orbit while your shuttle craft move equipment to the surface and set up propellant ISRU again, except this time you keep going and you get all your metal smelting and basalt fiber extrusion and everything else operating too. Then you put those building materials in orbit, and your ship uses them to construct some more nice big habitats. Repeat this process while also increasing production until you're building more habitats than you need, then convert some into ships and send them to colonize more asteroids.

>i am sorry but no commercial starship will be even close to flying next year.
They can launch Starlinks on the early, high risk flights no problem. In terms of "regular service", that'll probably be a few years but that's mostly just because many commercial payloads need to be designed for a specific launcher. I'd expect a handful of successful Starlink launches by the end of 2021 and maybe the first few rideshares either right at the end of the year or early 2022.

>>12208104
They'll destroy all their Earth assets the moment all their most advanced Starships leave in the mid 2060 launch window, from Boosters all the way down to the foundries that make their Raptor turbopump superalloys. Meanwhile, the Starships that departed Mars a month earlier to come back to Earth actually have no people on board, they're just full of sand. Twenty Starship aerobrake into various retrograde orbits, three of them crossing geostationary altitude, and they all open their payload doors and dispense their debris clouds. The ensuing kessler syndrome destroys all the significant space infrastructure around Earth, and grinds up those sacrificial Starships in the process.

Wrong. In fact, there are now more companies competing with fake meat industries. Their main progression now is scaling production. Fake meat of 2-4 years ago were low production.

The ONLY meat alternative that could potentially replace actual meat is cell based cultured meat. And the only reason that could actually replace meat is that, unlike your meme bean patties, it is meat.

Depends on resource. Whether cultured meat is better or bean/plant based fake meat.

Won't matter when either are artificially made with plenty of nutrients and artificial tastes.

That’s boring as hell. Meat is less fun when it doesn’t come from something you killed and skinned. You can make the bones into dice!

>>12208201
Your rock needs to be about 100 tons to even break windows on the ground, my guy. That's a terrorist attack. Sending a one hundred ton cloud of sand on a retrograde orbit through geostationary altitude is LITERALLY a globally devastating strategic act which fucks with everything from GPS to communications. As long as Mars can afford to expend a Starship every 2.5 years they can basically keep up perpetual zero-space-access Kessler syndrome at Earth, which means Mars becomes UNTOUCHABLE until such time as the Earth fags can either develop their own solution to the problem somehow, or until Mars gets big and powerful enough that they really need not fear retaliation from Earth because it would mean Earth getting their shit actually rocked.

I absolutely agree Mars cows are not the solution, finding a way to import the most genuine meat at the minimum cost is. I wonder if meat can be stowed unpressurized without damage.

>>12208274
It's not about "feelings", it's about the fact that hyperprocessed beans barely taste like meat and only vegans like them. Plus there's no evidence it's actually healthier than real meat, given all the sodium.

I did. Hyperprocessed beans taste like garbage. There's a reason that almost every restaurant that did a Beyond Meat promotion ended it. I think only A&W is still doing it.

>>12208319
Wonder how much they paid them.

>>12208319
There's a reason they did a promotion in the first place. No one will promote their food without first tasting it themselves. You're just conflating your own personal identity issues (with meat) with general public.

>>12208319
It's a little like being in prison.

Pussy is better, but boipussy is the next best thing if you can't get any.

It'll be like that for meat. Nobody is going to spend all of their resources excavating rangeland for cows when they can just grow beanpods and throw in some artificial flavoring. It's not anybody's first choice, but even if beef is available on Mars it will be on par with caviar or truffles in terms of rarity.

>For the cost of the program a much better vehicle could have been built from scratch.
The point of the program was to avoid doing that. Commonality with shuttle parts means commonality with shuttle JOBS, which were spread across every Congressional district over the course of 40 years. This makes SLS almost immune to the greatest threat to American rocket programs - Congress losing interest and changing its mind. If they'd done this with the Saturn family we'd never have cancelled it. Also >>12208290
it's 95 fucking tons to orbit even with the gay loser underpowered ICPS instead of EUS, and with SRBs instead of F-1B kerolox boosters. SLS dominates everything still flying other than SpaceX rockets.

SLS isn't even that expensive compared to the Shuttle if you're comparing it for cargo launches - nine times the payload for four times the price. Is it enormously retarded for manned launches? Yeah, probably. Would it get completely shit on for launch pace and cost efficiency if you put ICPS+Orion on a Falcon Heavy? Absolutely. It's still the biggest, baddest thing in the sky until Starship reaches orbit, and that just means the US will own the top THREE rockets by payload capacity.
>Starship

Literally the only things I'm still mad about are tossing historic SSMEs in the drink and the program delays.

>>12208349

Mars colonies will be 90% ISRU if we want to bootstrap them quickly into something effective and self sustaining.

Besides, beef will not taste good after that long. maybe jerky, but you'd have to somehow blend up the jerky and turn it into patties.

I'm not entirely convinced SLS will reach orbit before Starship. Superheavy is being built and last I heard they SLS was NET Q4 2021.

>>12208346
>not that difficult to make room for some dumb cows

yes it will lol

Even in countries like Japan, here on earth, cow meat is so expensive that it's a luxury for most people.

The amount of space you need for one cow will feed multiple humans definitely. Unless we're building pressurized bubbles the size of cities, we won't have cows, and even then it'll be a niche luxury good.

>>12208368
what if we filled the mariner valley with sulphur hexaflouride up to 1atm of pressure and let cows roam free with only an oxygen tank

free range Mars cows, imagine

These are important spaceflight related issues, and I'd appreciate it if you wouldn't interrupt this important discussion.

>>12208371
>Unless we're building pressurized bubbles the size of cities
I thought that was always part of the plan for serious Mars colonization - dome over Valles Marineris or pressurize some of the monster lava tubes in the megavolcanoes.

Also, we WILL need plant based CO2 scrubbing at some point, so having cows around to convert excess grass into dairy and meat is a no brainer at that scale. The limiting factor will be water.

>>12208373
How are they supposed to chew the grass with the oxygen tank on?

Towards the later stages of colonization, cowdomes might work, but it couldn't be a staple food even then.

You can fit a cow in a 3 meter by 3 meter box. Make a warehouse from steel and cover it in regolith.

> Even in countries like Japan, here on earth, cow meat is so expensive that it's a luxury for most people.

No it isn’t. Beef is cheap shit you can get from any McDonald’s, and the food of choice for African pastoralists.

Make more space.

Exactly this.

Cows need space or they'll be unhealthy and shit.

There's a reason they don't do battery farming with cows the way they do with chickens.

>>12208399
I'm not convinced. Starship is supposed to be a low cost system, in order to make colonization feasible. It's all about the $/kg to Mars. So we should be looking at ways to compress meat, like dehydration.

On the other hand, would flooding the Mariner Valley or some large crater with sulphur hexaflouride actually work for raising the atmospheric pressure to habitable levels? Because domeless crater cities would be dope.

If it's ammonium perchlorate the dirt itself becomes our oxidizer for SRBs. Use SRBs for transportation everywhere to fill the atmosphere with nitrogen compounds. Grow sugars with aquaponic plants, and make rocket candy. The only external inputs you need are a magnetosphere and water.

The whole reason we're going to Mars instead of the Moon or Venus is the comparatively large amount of water. If Martian water proves infeasibly expensive to harvest, the whole colony idea is scuppered and we'll have to crash Ceres into Mars.

Comparatively water that needs to be mined in large quantities and only as large as a single lake on Earth. If Mars as colony is to survive more than 10 years, they need to utilize the water 1000x more efficient than that on earth.
