Hey this bread is pretty good so far. Does anyone know how much it costs SpaceX to make one Starship? I know launch costs but not build costs

This makes the shuttlefag piss and shit

>>15338865
>Does anyone know how much it costs SpaceX to make one Starship
no. best you can get is steel cost + raptor cost + employee cost by counting cars.
>I know launch costs
You don't. Every number you ever heard was aspirational.

>>15338865
No one knows

>>15338859
I mean that starship's plume is cooler looking then the shuttle's plume.

>Starship hype train only gets to exist until it gets a few launches under its belt and we learn what (admittedly huge) problems it has.
Luckily it's unmanned. They're going to heavily iterate the design until it works.
Even if they have to bring back sweating heatshield

>>15338880
What admittedly huge problems does it have that everybody else (including SpaceX) can't see but that you can see so clearly?
>>15338882
You and the other poster are the same types of people who said F9 would fail and F9 reuse wouldn't work out. Yet SpaceX has gotten F9 reuse down to two weeks and that is with kerolox engines that get filled with carbon residue after every launch.

>>15338889
didn't even know labpadre had a update channel too

Starship cannot survive even a single tile falling off
>inb4 muh steel
Ah yes your mm-thin steel skin should surely protect you. It’s not like it will fail or anything!

The anti SpaceX shills on sfg (who are undoubtedly largely employees or investors of failed companies like ULA, Blue Origin, Arianespace, Boeing) always just move the goalpost when their predictions about how SpaceX will fail end up being dead wrong. Unfortunately for them, moving goalposts doesn't lead to more launches.

>>15338897
Everybody knows it'll fail first. Dilate tranny.
https://www.youtube.com/watch?v=hyYqLaeHM7g&t=977

All the tiles that fell off S24 during testing weren't even caused by vibrations, but by strikes from concrete debris.

I just don't get the hype, it's just a bunch of inefficient methane engines strapped to a hull. The RS-25 used liquid hydrogen and it shows.

>>15338908
Bait

The anon from the other thread who said that sfg is awful when its on the first page wasn't wrong.

I really would like it to do everything musk promises and then some. but somehow I don't believe it. you're telling me this thing is going to drop launch costs and turn around times by two orders of magnitude? over other already reusable designs by the same company? we will see.

>>15338909

>>15338915
>What is density
Liquid hydrogen result in a heavier vehicle. It's actually worse.
https://www.youtube.com/watch?v=-vVagY3O2Rc

>>15338918
That is a heavier vehicle for same delta-v. Less delta-v for same tank.

>>15338916
Jesse we have to cook

>>15338918
Retard, TWR is completely different to ISP.

>>15338912
Low effort concern shilling.
>reentry is too inconsistent to carry humans
With the current design and engine power, starship can bring 150 tonnes of cargo into LEO. SpaceX could just bite the bullet and use a much heavier heat shielding system that is much more reliable and end up with 120-130 tonnes instead.
>repair and recertification is prohibitively expensive
There isn't any indications that this would be the case, especially given what we know about Falcon 9. These are the same anti-reuse arguments people made against the Falcon 9.
>the tower actually can't catch the booster. you need a new one every launch. maybe if you're lucky you can salvage a few engines
Ok, just bite the bullet and add landing legs to the booster.
>everything works as intended but they estimated too thin of margins. redesigns drop the payload to LEO significantly
Extremely unlikely.
>but somehow I don't believe it. you're telling me this thing is going to drop launch costs and turn around times by two orders of magnitude? over other already reusable designs by the same company?
Falcon 9 has more expensive engines, more expensive construction material, has to use helium, uses more expensive fuel, and is only partially reusable.

Pretty much everything you bring up is something that SpaceX has probably already considered and investigated 1000s of times. And they're a lot smarter than you.

>>15338922
>TWR
missing the point. you sure are retarded.
you need a bigger (heavier) tank to bring the same amount of deltavee.
You need more insulation.
It's unironically a less efficient rocket overall

>>15338891

>>15338925
NTA but you're a retard

Why didn't they continue this shit? https://en.wikipedia.org/wiki/NERVA
It was tested and built in the 50's with turbopump, and demonstrated an ISP of 842s, and thrust ~250kN in vacuum.

we are SO back

Has anyone done the math whether Starship HLS can go from LEO to the Lunar surface and back?

>>15338925
I doubt they have thought about everything, that isn't really possible and not how they operate
that is how Nasa *tries* to operate, it just means massive cost and kind of middling results
SpaceX does rapid iteration, there will be failures, but thats fine, they will iterate, try again and eventually succeed
the initial goals might not be achieved 100%, but Starship will still be completely revolutionary even if the cadence and cost is not as good as planned from the beginning

>>15338988
I don't think they've thought of everything, but basic things like heat shield alternatives, landing legs, etc are definitely things they've spent a lot of time considering.

could they not do some sort of preliminary testing on, like, the vomit comet to determine if zero-g chemistry will even make a difference to begin with? also
>mach 25 hypersonic reentry
yea and what are the deceleration G-forces going to be like? if they're worried about 1G affecting the macroscopic structure of their drugs then what's a protracted 6Gs going to do? feels like some kind of investor bait; OTOH, they could probably buy an entire starship and just park it in orbit with a fully stocked chem lab and then buy a F9-Dragon flight to rendezvous with it and have a full-on private space station for under $200M, which would be enough for real volume production

the stupidest thing they could do is scale up their current architecture and have the entire lab - robots, instruments, and all - built into the reentry vehicle. really they should be working on designing something that takes only the finished product down, and a permanent robotic lab that can be restocked.

>>15338927
S-IVB: gross mass 123t, delta-V ~9km/s.

>>15339014
>if they're worried about 1G affecting the macroscopic structure of their drugs then what's a protracted 6Gs going to do
A lot of drugs and high-tech materials like graphene are incredibly hard to create, but once they're synthesized they are completely stable so the deceleration shouldn't matter

>>15338993
well, it could do some military maneuvers that were never used

>>15339033
I'm comparing it to a fully-fueled starship 2nd stage, to S-IVB in orbit, because they're both just cargo-carrying boosters. Liquid hydrogen is far more efficient even with its insulation problems.

Whats your plan of action in steps for establishing a lunar colony and economy if you were given full reign of SpaceX?

>>15339039
That's still more efficient than methalox retard.

>>15339020
>>15339033
The point is if you made Starship hydrogen it would make it heavier and decrase its payload capacity.
For example can have a 100kg SEP kick stage as payload and say mass: 100kg delta-v: 30km/s that doesn't mean anything.
Similarly if you made a three stage expendable vehicle and made SIVB and SII both be methane they would be higher performance.

>>15336984
the Soviets NEVER should have tried to build the N-1 as a reaction to the Saturn 5 (just like they shouldn't have sunk their resources into building the zero-net gain Buran as a reaction to the Shuttle), they should have consigned themselves to Earth-orbit rendezvous scheme and built their moon-going spacecraft from 2 or 3 launches of their existing rockets, they would have made it to the moon (but maybe not before us) if they had.

>>15339060
You're talking mass wise? I don't think so 27.5 * 5000/2000 <<< 150

>>15339087
ksp doesn't take into account the fact that you can't use the same tanks for methane and hydrogen. Hydrogen requires heavier tanks because it tends to penetrate thinner tank walls. The larger the tank needs to be, the less attractive hydrogen becomes, and hydrogen tanks will always be large because of its low density. This isn't even mentioning the fact that hydrogen engines have to be vastly more complex than equivalent to stop hydrogen going places it shouldn't.
It's an all around a terrible choice.

TWR is a modifier to ISP ASL
if your TWR is 1 your rocket doesn't move, 100% of thrust is combatting gravity
if your TWR is 2 your rocket goes up at 9.81m/s, 50% of thrust is combatting gravity
in other words, the more thrust you have per weight, the less of your fuel is wasted on fighting gravity.

now that i think about it, it sounds like a thrust to weight ratio of 10 that only thrusts for like 1/5th of a second at a time would be good

So I took the insulation mass for the space-shuttle fuel tank and compared that to the starship fuel tank (only 2x the mass). The plot shows the y-axis being the total mass needed to achieve a certain delta-v on the x-axis (the engine weight is a - assumed to be the same). The black plot is RS-25, and the red is raptor - black is more efficient.

I meant to say the ratio between the dry mass and total mass of the fuel tank. These should be proportional to insulation-to-total mass ratio.

>>15339211
The 2 ratios you see correspond to dry and wet mass values on wiki, for both the space-shuttle fuel tank and starship fuel tank respectively.

>>15339216
making hydrogen is much easier than making methane, just pass some electricity through water
its about ease of storage (you need to store it for years on mars) and performance getting to LEO where I think TWR is more important and methane engines have an advantage compared to hydrogen engines
I guess hydrogen does have an advantage in space, but generally just a pain to work with and making the lower stage booster and starship itself use different propellants would be a massive pain in the ass
and then one thing is hydrogen embrittlement, how is that going to affect rapid reusability? is it going to fuck the rocket structure up completely way quicker?
also being a pain to work with generally, leaking through everywhere etc would make rapid reuse and the related infrastructure more brittle
maybe there was a way to fix these problems, but damn that is a lot of problems that you have to deal with when you want to use hydrogen
and for what? slight increase in dV when already in orbit?

>>15338824

>>15339183
It isn't even a linear relationship between total and dry mass for fuel tanks. Since insulation is proportional to surface area not volume. Meaning that no matter how much more insulation you need for hydrogen, after a sufficiently high x-value, it'll take less mass for the RS-25 rocket to achieve the same delta-V.

> Hunter-Scullion said he is in talks with a company to conduct a mission in early 2026 to collect samples from the moon. Beyond that, the company is eyeing a mission to an asteroid by around 2031.

> For AstroForge’s test flight next week, the company purchased a “rideshare” that allows their small spacecraft to be one of several payloads aboard a SpaceX Falcon 9 rocket. Programs like that simply didn’t exist even a few years ago, and it’s one key way that AstroForge is able to move quickly and keep costs manageable.

> The goal of AstroForge's first mission is to demonstrate that the company can refine materials successfully in low-Earth orbit. This will involve heating a piece of metal until it turns from a solid state into a gas, then bombarding it with microwaves to ionize the gaseous metal, or positively charge the atoms. Magnets will then be used to separate out valuable metals from other materials that might be present on a space rock.

It's the most realistic fusion rocket design but it doesn't get any attention here because it actually uses solar power and doesn't need high Q fusion to work. Nucleartards are their own worst enemy

I guess NASA would demonstrate it first, then let others use their rated technology after approval. Not that I have any idea

Other than tile trouble on re entry, what are the most likely failure modes for OFT-1?

>>15339312
Max Q
Staging

>>15339183
You actually gave Starship an advantage. The second stage is 90 dry and 1300 wet. 3680 is the booster.
The comparison is lacking though. Starship needs to withstand reentry and Max-Q. The ET is heavily supported through Max-Q by the two very thick SRB casings each of them three times the weight dry that it is.
When you look at the whole system instead of comparing a tank to a whole vehicle you'll see closer to the full picture. >>15339065

It will sure be interesting.

>>15339345
that's not lunar regolith dumbass, they say it's a regolith "simulant" in that chapter, whatever the fuck that is. At least check the sources of your schizo spergouts.

>>15339348
it's the closest thing to lunar regolith and it came directly from NASA in order for the myth busters to debunk claims of a faked moon landing

That would take up too much footage to do it convincingly, and it overlooks the rest of the moon program.

>>15339351
You can tell we went to the moon because there’s not a chance in hell the soviets would let us fake it. But of course if I bring that up you schitzos would just shift the goalposts to some cabal NWO and how the cold war wasn’t real.

That is the number 1 reason the moon landing isn't real. If you think the moon landing isn't real you have to prove literally every government is controlled by the same people and everything is fake, which is an even dumber conspiracy.

>>15339711
what's this from

>>15339014
They actually do a fair bit of chemistry on 0g flights, but there are two problems, you only experience microgravity for a short period of time, which may be below the time needed for your reaction/crystallization ectopic.

The second issue is safety, these flights are manned, and typically multiple experiments are performed on a single flight, which means whatever reaction you perform you need to ensure does not have human consequences. Even if you flew the robotic setup they've made, the plane still has a crew you need to keep safe.

>>15339784

>>15339039
It will be real interesting to see when Starship starts surpassing other vehicles total up mass.

This bread is worse than the last. Lets get back to spaceflight.

>>15339878
No, the "great men" were just riding the waves of inevitable change, history would mostly stay the same even if those men never existed. The actions that make the most change are the ones that aren't actually planned, like a king not leaving an heir and causing a war over it.

Just because he tweets shitty reddit memes doesn't make him a genius or deserving of credit for spacex's accomplishments, which are commendable but not impressive - it's just 2 dumb boosters to LEO ffs, we landed on the moon in the '60s! Where have our standards gone?

>board spaceship out of college
>go (whether boldly or timorously) where no man has gone before
>see other worlds with your own eyes
>conduct multi-year observation campaign
>return home in time to retire in our own comfy solar system
Whyever not?

At 0.2c, a trip to the nearest stars would take ~20 years of travel, plus 4 years of comms lag to start receiving data. Or ~40 years (plus however long you spend there making observations) for the ship to return with full data, samples, etc.

You say "travel", so I assume you mean manned -- that's certainly a huge leap from our longest manned missions. But compared to robotic missions in the solar system, that's not an unreasonable timescale at all. Consider Voyager 2, which spent 12 years from launch till its Neptunian flyby, and is still making interstellar observations 45 years later.

>>15340154
I kind of doubt its purely about the memes, I mean not impossible for Elon, but the scenario I have in my head is there are two choices (or more) for more or less "pointiness" and its not immediately clear which one of them is optimal
less pointy: more cargospace, easier to manufacture tiles
more pointy: better aerodynamics and control (just speculating)

if one of them is not the clear winner then maybe he could have made the decision based on memes or how funny he thought it would be, if it turns out to be bad then they can always change it and at least that dev direction has been explored

>>15339333
>Elon admits to what I've been saying for two years now and confirms what I've been ranting about what needs to be done to Starship

Holy shit, I feel so vindicated it isn't even funny. If I was a schizo I'd actually think he read my posts. Literally every fear I had concerning SS was related to the extreme drop in internal volume over time, which would be fixed by getting rid of the point and lengthening it; and of course adding more RVACs to account for the greater tonnage capacity you've given yourself in the process.

She was the first woman to command the ISS twice, and holds the records for the oldest woman spacewalker and the most spacewalks by a woman1. She is currently the Director of Human Spaceflight at Axiom Space and will be the mission commander of Ax-2. This will be her fourth spaceflight .

>Ali Alqarni: He is one of the members of the inaugural Saudi national astronaut program from the Kingdom of Saudi Arabia (KSA). He has a master’s degree in mechanical engineering and works as a researcher at King Abdulaziz City for Science and Technology (KACST). He is interested in robotics, artificial intelligence, and renewable energy. He will be a mission specialist on Ax-2. This will be his first spaceflight .

I don't know if this could really be called a tourist mission this time? More like Saudis getting two random engineers into space for reasons

ax1 was basically purely about tourism, ax2 doesn't really look like that, but not sure
John Shoffner kind of looks like a tourist desu, and the saudis are basically "tourists" in the sense that they are going because their government wants clout basically, at least that is what it looks like to me
