Doing what? One-dimensional thinking like this is how you get SLS
Space doesn’t have a market, it needs LESS people in the industry than are actively applying

>>16152412
i'm doing my part to help by just complaining about the industry on /sfg/ instead of actually working in it

>>16152414
Okay based actually kek

>>16152400
at what point do they give up on upper stage reusability and settle for a cheapish partially reusable super-heavy lift vehicle

>>16152414
>>16152405
i appreciate your complaints, i need anything i can get to work at starbase once im out of college.

>>16152417
Upper stage reentry and landing is 100% necessary for the Mars thing so I doubt they will give up. It's clear that this vehicle will never visit Mars, so maybe they will give up on this one, but they always talk about how there will be an 18m width vehicle in the future. I think that will be capable of the 150t fully reusable thing, but it probably wont have reusable launch pads.

What will (You) do if the Mars ticket price drops to $100k?

wait so what is this? a mockup made with the construction techniques of the real thing that won't undergo testing? are they building two more before they fly any?

>>16152427
if it gets that low, demand will putpace supply. im expecting 1-2million minimum by 2050, and planning accordingly

OFT stands for orbital FLIGHT test, the fourth is scheduled for end of May according to FAA / Space-X

https://youtu.be/1oHWpddbsRM
In case u missed it

>>16152449
I have AC

>>16152455
you seem to not understand what orbital means, and the FAA as well as SpaceX call it Integrated Flight Test or IFT. check your defintions xister

>>16152458
i think you got your info wrong. FAA clearly says OFT in all legal documents and license permits!

>>16152460
seems more to me like you inspect elemented that and also cut off your manhood since you didnt link anything. why dont you fuck right off?

Interplanetary transport system (ITS) - Super Heavy (SH), Starship (SS)

>>16152461
I'm sorry you had to find out this way. IFT or "integrated flight test" is sadly nowhere to be found on any existing FAA license

>>16152463
proof elon LIED about it not being orbital

>>16152445
I sure hope they aren't still doing flight tests by orbital 4

>>16152465
Every launch from Boca Chunga is by definition a test launch

>>16152456
redpill me on who are these two people?

>>16152466
It’s a regular launch, there is no distinction. It’s de-facto classified as a “Success, Partial”

It's penciled in as "OFT" for tax reduction purposes and circumnavigating FAA restriction involving non-orbital tests.
Think about it logically.

>>16152468
no, because the modified license is not operational. it's a very strict legal framework, and a test license

>>16152470
every launch should be taxed

Been reading up on RTGs and after looking into thermoelectric generators without the radioisotope component makes me wonder, would it be practical to use the Seebeck effect to take excess heat from spacecraft and space stations and use that to simultaneously generate power while cooling the craft?
Since most spacecraft seem to be more focused on dispelling excess heat that is generated rather than having to generate heat on their own to stay warm. Obviously it wouldn't do much at the scale of current spacecraft, but it could be scaled for inhabited megastructures that could struggle with radiating heat fast enough to stay comfortable. This is assuming that the efficiency of thermoelectric generators improves in the near future.

very strange to me how there has always been a drive to bend over backwards making things as safe as possible for astronauts, but at the same time housands of men die in wars all the time and noone cares. Why is there such a double standard?

>>16152523
because when thousands of men die in wars the army doesn't get hit with congressional investigations and budget cuts. it's a matter of national prestige and that's worth a lot more than a single life.

>>16152523
The men who die in war are just considered more disposable because they aren't highly-educated, trained, and healthy. Instead they're just healthy (most of the time). Although many astronauts, especially during the first years of spaceflight, were military men.
In general most men are considered disposable, especially those of lower status due to lack of education, physical attractiveness, or socioeconomic strata. It's why no one cares if a middle-age man kills himself but a young woman committing suicide is a tragedy that makes local or even national news.

>>16152523
War is dangerous? Hmmm that’s a mystery

>>16152526
space is dangerous too.

>>16152496
>Jews telling what I can and cannot do: space edition
No

>>16152523
What is the vapid point you're trying to make? Do you think soldiers just get sacrificed and that leaders and fellow soldiers don't do everything they can to keep that from happening? The nature of conflict necessitates risk. There really isn't such a thing as a "safe way" to attacking an enemy machinegun position anon. But soldiers and armies don't go out of their way to just get killed with no regard to safety. But war given its nature, demands sacrifice. It's almost as if that's an instinctual virtue or something.

>>16152530
Okay-so you obviously see these safety measures we take for space
We also take geopolitical safety measures; sometimes in the form of war.

>>16152496
>waaahhh if we let people colonize space they might drop rocks on us
Well yeah

>>16152523
>why do people try to kill people in the killing people contest?
also war has literally never been safer for a soldier in all of human history.

>>16152540
>also war has literally never been safer for a soldier in all of human history.
>*Dies from enemy DPICM strike along with the rest of his entire company*

>>16152537
Word salad and missing the point.
I didnt say people go out of their way to get killed in war buddy. The fact is no-one cares when they get killed, but if several thousand people died in spaceflight everyone would lose their minds.
14 people died on shuttle so it was viewed as a travesty and they cancelled the program. If 14 people died in a war do you think politicians get together to cancel the invasion? No. And your pseud stuff about risk or whatever is redundant because it all applies to space.

>>16152542
yes it's much safer. read casualty reports from basically any war. check the portion of wounded to killed, the number dead from disease, and the portion of dead to mobilized, as well as the health outcomes from specific injuries, notably burns and limb damage. and civilians are far and away the safest they've been in recorded history

>>16152543
>typing all of this
>calling anyone else a pseud
you are genuinely fucking retarded for wondering why people die in war. they die because killing people is literally how one wages war. killing is war and war is killing. one cannot wage war without killing, on BOTH SIDES. since you're both trying to heckin unalive each other, youre gonna get corpses. in spaceflight killing people is unnecessary. it's a contest between man and nature. In war it's a contest between man and man to see who is to goodest at killing
the fact that this isn't readily apparent to you marks you as a 14(IQ)andthisisdeep tier retard

but I think we should give less of a shit when astronauts die

A much better question is:
“why do we accept death as a ‘necessity’ in war, but ‘not an option’ in human spaceflight?”
Personally I think it’s because you’re mobilizing hundreds, thousands, sometimes millions to front lines of an enemy trying to kill you. But in spaceflight, it’s been a mere 60 years of sending up one at a time, two at a time, seven at a time max. Every individual is way more personal and special and worth trying to keep alive. If we ever commit hundreds, thousands, millions out into LEO, the Moon, and Mars then dying off Earth will become way more of an “inevitable” thing as it is just probabilistically going to happen, like car crash fatalities or passenger plane crashes.

>>16152544
>read casualty reports from basically any war. check the portion of wounded to killed
Modern militaries have extremely high combat personnel to non combat personnel ratios due to the mechanization of modern militaries. The bulk of an armored division (60-70%+) would be comprised of non combat personnel. hence the skewing of data. It should also be noted here that casualty reports from low intensity conflicts like Iraq and Afghanistan don't contain casualties from either host nation forces, private military contractors and police forces, who took the brunt of enemy action during said conflicts.

>the number dead from disease
Vietnam was the last war where US forces were exposed to the elements for long periods of time and weren't mostly operating out of combat outposts, and you still had high numbers of casualties due to disease.

I can't see how you can think war is "safer" now. Everything is more lethal.

>>16152547
Why are you so mad? And why do you think you need to explain retarded shit to me like its some hot take? I never once asked why people fight wars. You are arguing with the voices in your head.

>>16152549
>“why do we accept death as a ‘necessity’ in war, but ‘not an option’ in human spaceflight?”

Nigga do you know how fucking dangerous spaceflight is? Those motherfuckers knew the immense risks involved and were willing to take the risk, same thing soldiers do in war. You take fucking risks.

>>16152533
they can't have you escaping their political, economic, and cultural control, uppity goy

>>16152555
What’s your point?

>>16152554
so you're too stupid to understand why the killing people contest results in dead bodies?

>>16152549
>“why do we accept death as a ‘necessity’ in war, but ‘not an option’ in human spaceflight?”
spaceflight is always under spotlight, and people going up there were highly trained very capable people. the optics of them dying are bad.

I'll do you one better, why do we accept death as a 'necessity' at all?
we should do away with death, so humans only occasionally die in the most unpredictable of accidents and nowhere else

>>16152560
honestly just take a moment off the electronic devices to calm down. see you tomorrow : )

>>16152562

It is though. Despite every opportunity to develop different rail infrastructure almost everyone uses British gauges or very close to them.

>>16152963
If the orbiter and boosters were fully and rapidly reusable then using a drop tank was an amazing decision.
Think about it, it would have been like the falcon 9 but better. Instead of spending an entire stage with all its avionics and engine every flight, you just spend a drop tank, which would be very cheap in a mass manufacture situation and would also have plenty of margin to be used as orbital fuel depots for deep space missions if the Shuttle wasn't nerfed.

>>16152993
So really it comes down to the cripplingly low cadence. If that was improved Shuttle could have been amazing
That sucks

even without the context, he's not even reacting to the sound of it hitting the floor. Don't mind me though, keep baiting the retard.

>>16152998
the plan for the year after challenger was 24+ flights, which by oldspace standards is pretty good

>>16152998
Yes. Risk aversion was the main problem, which led to low cadence. Cadence was ramping up before Challenger, then cadence never recovered and a whole host of Shuttle capabilities like carrying cryogen deep space stages were scrapped forever due to safety.
SRBs were retarded because the fuel is the most expensive and complex part so it makes no sense to reuse them, they basically added a very high lower bound on launch cost, which was the cost of two gigantic missiles. The tech wasnt ready at the time, but if NASA had droneship recovered boosters they would have been over half way to solving the Shuttle.
There were a whole load of things with the Orbiter which turned out to not be reusable, or at least not without extensive repair every flight. Maybe they could have been fixed if rapid iteration was allowed, but I fear Starship is going the same way, despite all the prototyping.

>>16153024
>I fear Starship is going the same way, despite all the prototyping.
Can you elaborate on that?

>>16153037
>Never proven easy rapid reuse of Raptor, or any reuse of Raptor for that matter
>Heat shield clearly not rapidly reusable in the present config and is only getting more complex/hard to maintain (basically becoming the same as the shuttle shield)
>Launch site not rapidly resuable in the current config
It's impossible for it to work with any of those present factors.
It's worse when considering the frankly already bad payload for a vehicle it's size. Falcon 9 added more heat shielding on block 5 which is why there are black areas. Block 4 was recoverable but not reusable due to thermal ware on the vehicle. Inevitably this will happen to Starship, and the performance will get worse. They also need a total redesign of Raptor. Musk said it many times and it's true. Present raptor dumps water into the tanks which then freezes to ice and clogs the engine inlets. It was responsible for the IFT2 and 3 RUDs. And clearly tanks which get filled with water ice are not rapidly reusable.

>>16152496
>literal jewish propaganda

>>16152993
I don't understand the fully reusable meme. Just shit out unfathomable numbers of upper stages. We can still get to Mars

is there a goldilocks zone for gravity wells? apart from the obvious requirements for us as humans. supposing we have advanced enough tech (genetic engineering/synthetic bodies whatever) and no energy issues, what is "the best" gravity well to be in? more than Earth? less?

If we lived inside a nebula would scientists actually think the aether exists like they did in olden times?

There's a theory of social catastrophe along Malthusian lines that predicts war or something involving similar violent loss of life when the number of young, unmarried males rises too high in a population.

From that perspective war is an unfortunate but necessary correction, because those who die in the largest numbers are young males and their death corrects the gender imbalance.

>>16153238
so we're farmed like animals?

>>16153238

Truly necessary, sure, but it's been said that graveyards are full of necessary people; if they really are truly necessary then training up a replacement ought to be priority zero just in case they get hit by a bus or something. And you can't really have a functioning organisation without trustworthy people. Excellence does seem to at least be somewhat implied by necessity, though.

This is a reason why africans are notorious for violence. They fought in atomized warrior bands where the storngest survived and took the women. Europeans and Asians have lived thousands of years in agricultural societies where the state chipped away at it's warrior generations by expending them in wars, where their fertility is actually far lower than non warriors, unless they get to rape a lot when they win. Often men would even be conscripted for life into the military basically making them incels. That combined with the pruning away of violent and antisocial behaviour through wide use of the death penalty produced modern man.

The solar thermal anon must be really happy.

I don't understand this mindset of "EVs will never replace ICE cars"
I charge at home every day and leave with a full battery. People who can't charge at home can charge at work. It's not hard to build public chargers. We did it with gas stations which are way harder to maintain. And for road trips, you have superchargers.
I think EVs work for at least 50% of the Western world's population. Worries about battery replacement, poor performance in cold weather, low range, are all leftovers from the first generation of EVs from 15 years ago and aren't relevant anymore.

>>16153493
Unless you're also including the electricity -> biofuel efficiency step, this isn't exactly like to like. Many things are able to substitute in electricity for fuel (e.g., most people's cars), but some things really do need fuel for either density/specific energy reasons (e.g., planes, rockets) or needing to be refuelled quickly in harsh environments (e.g., tanks). I do agree that most biofuel production is stupid and wasteful, but we're going to need _some_ either biofuel or synthetic fuels indefinitely for these uses.

>>16153491
Due to extensive research done by the University of Pittsburgh, diamond has been confirmed as the hardest metal known to man. The research is as follows. Pocket-protected scientists built a wall of iron and crashed a diamond car into it at 400 miles per hour, and the car was unharmed. They then built a wall out of diamond and crashed a car made of iron moving at 400 miles an hour into the wall, and the wall came out fine. They then crashed a diamond car made of 400 miles per hour into a wall, and there were no survivors. They crashed 400 miles per hour into a diamond traveling at iron car. Western New York was powerless for hours. They rammed a wall of metal into a 400 mile per hour made of diamond, and the resulting explosion shifted the earth's orbit 400 million miles away from the sun, saving the earth from a meteor the size of a small Washington suburb that was hurtling towards mid-western Prussia at 400 billion miles per hour. They shot a diamond made of iron at a car moving at 400 walls per hour, and as a result caused two wayward airplanes to lose track of their bearings, and make a fatal crash with two buildings in downtown New York. They spun 400 miles at diamond into iron per wall. The results were inconclusive. Finally, they placed 400 diamonds per hour in front of a car made of wall traveling at miles per iron, and the result proved without a doubt that diamonds were the hardest metal of all time, if not just the hardest metal known to man.

>This is where Portal Space believes it has a solution. Thornburg says the company is developing a spacecraft built around the concept of solar thermal propulsion, which uses solar energy to heat propellant and produce thrust. Such engines have been studied for decades, but have never been developed for practical purposes. The company has not disclosed its propellant of choice, but Thornburg said it is storable on orbit, and not toxic like hydrazine. (It might be something like ammonia.)
>He envisions a fleet of refuelable Supernova vehicles at medium-Earth and geostationary orbit capable of swooping down to various orbits and providing services such as propellant delivery, mobility, and observation for commercial and military satellites. His vision is to provide real-time, responsive capability for existing satellites. If one needs to make an emergency maneuver, a Supernova vehicle could be there within a couple of hours.

I don't use twitter what's that? like clapping groupies?

Elon Musk recently disclosed a serious issue with the current iteration of the vehicle. Starship is facing a 50% underperformance in terms of the payload which it can deliver to orbit. If this issue is not rectified, it could have grave implications for Starship’s ability to complete a lunar mission.

They're rectifying it with bigger engines and larger propellant tanks. We knew that already.

it's like stans. they will never meet him, he will never be their friend, but they never miss a chance to suck him off or cope for him (which is great, go for it. i suck elon's cock too sometimes). the difference is they make it their whole fucking life, so seeing them get unfollowed for a minor transgression is amusing

Is Mike Griffin trying to be Trump's next NASA admin appointment?

>>16153740
Trump isn't going to be the president, though.

>>16153741
He has been president this whole time?

was there election shit on /sci/ last round? am newfag for a few months only

>>16153747
this isn't /sci/. go back they're

>>16153749
understood x'ir

>>16153738
NTA but you can't fix it with this diameter ship. The core problem is that ISP is like 10 seconds lower than advertised. That's why they never shill the ISP anymore. They can't fix it so they are trying to just increase mass flow to lwoer gravity losses.

>>16153751
whatever works

>>16153751
>ISP is low
Citation needed there, ol' chum

Why do retards pop in to /sfg/, even just /sci/ asking about politics bros?

>>16153751
shut the fuck up 18 meter diameter starship fag. it’s not happening

ISP in the context of rocketry stands for "specific impulse," which is a measure of the efficiency of a rocket engine. It represents the amount of thrust produced per unit of propellant over time and is typically expressed in seconds. The higher the specific impulse, the more efficiently a rocket engine converts propellant into thrust.

As for "Starship," you might be referring to SpaceX's Starship spacecraft, which is designed to be a fully reusable spacecraft for missions to Mars, the Moon, and potentially other destinations in the solar system. The specific impulse of the engines used in the Starship will depend on whether you are referring to the Raptor engines meant for the Starship itself or the Super Heavy booster meant to lift it.

As of my knowledge cutoff in 2023, SpaceX's Starship uses Raptor engines that are methane/liquid oxygen-powered and have a specific impulse that varies depending on whether they are in a vacuum or at sea level. For the vacuum-optimized version (Raptor Vacuum or RVac), the specific impulse is higher, possibly around 380 seconds or more. For the sea-level version, it is slightly lower, possibly around 330 seconds or more, due to atmospheric pressure affecting the engine's performance.

Please note that these figures are subject to change as SpaceX continues to develop and test the Starship and its engines. For the most current and detailed specifications, you should refer to the latest information released by SpaceX.

It will be the version that will go to Mars andactually take 100 people, so either it happens or musk will never go to Mars and has swindled all of us.

18 meters would be silly, but 12 meters would honestly be a good number for hitting the propellant masses they're looking for and giving more room for larger engine nozzles.

>>16153761
18m is best. 12m might be best for purely aero reasons on ascent, but a super fat starship is best. It provides the obvious advantage of a wider base so you can land on unprepared surfaces with greater tolerance and without big heavy legs. And crucially if the vehicle is going to be flying multiple times a day then being too long is a showstopper because it lowers your tolerance to high level winds so you can never do reliable on demand point to point travel.
