Would it be feasible to set up fueling stations in between Earth and Mars on a Solar orbit to allow for spacecraft to commit fast burn flip burns from Earth to the fueling station, then towards Mars?

>>11680517
I'm just that good

>>11680535
The delta v for slowing down, fueling then speeding up again would probably not be worth the extra burn time

>>11680535
I don't think so.

idk. The thought of accelerating at .3-.5 g then decelerating to refuel to then repeat the process to arrive at Mars within like a week seems pretty fucking rad to me.

>>11680498
Isn't this basically the Starship lunar proposal except with refueling instead of disposable kick stages?

>>11680548
If you accelerated to X velocity, and waited 4 months, then decelerated at Mars, you'd have got there a lot faster than a spacecraft that accelerated to X velocity, decelerated to meet up with a propellant depot, refueled, and then accelerated to X velocity again, several times. Problems with somehow getting fuel stations into position along the way notwithstanding, using that method offers literally zero advantage, because if you have the technology to reach speeds greater than X by enough that fuel station hopping could get you there faster than a straight shot, you'd just do a straight shot at that new top speed.

Basically your idea makes no sense.

>>11680623

>>11680649
Kind of? The point is that we could do Artemis with F9/FH no problem, and the total launch costs for the entire program- from testing to boots on the ground- would probably amount to less than a single SLS launch.

What you're doing is designing a spacecraft that only require half of the DeltaV than a spacecraft that would try to make a straight shot from Earth to Mars. With the refueling strategy, you design a spacecraft that has enough DeltaV to haul ass and accelerate/decelerate to the fueling station where you refuel and repeat the process from the fueling station to mars. So now, instead of put put putting your way to Mars at an acceleration of 0.01-0.1 g with coasting sessions. You're accelerating/decelerating constantly at half g from Earth to the station, refueling, then hauling ass again straight to Mars. Compare it to cars. You have one car that's extremely fuel efficient but doesn't go faster than 25. You can make the NY to LA run on one tank....But you can only do 25. vs. A sports car that can go 185 down the freeway (fuck the police). You bet your ass you're gonna have to stop a couple of times between NY and LA to refuel, but end of the day, you're getting there a hell of a lot faster than the put put car.

>What you're doing is designing a spacecraft that only require half of the DeltaV than a spacecraft that would try to make a straight shot from Earth to Mars.
So it can only go half as fast.
>With the refueling strategy, you design a spacecraft that has enough DeltaV to haul ass and accelerate/decelerate to the fueling station where you refuel and repeat the process from the fueling station to mars.
Except it can only go half as fast. Do you know what delta V even is?
>So now, instead of put put putting your way to Mars at an acceleration of 0.01-0.1 g with coasting sessions.
We don't do that, nobody is doing that. Any chemically powered mission to Mars burns at ~1 to 4 G's for about ten minutes, then coasts at high speed for 4 to 6 months, then either propulsively slows down to capture or aero-brakes in Mars' atmosphere to capture.
>You're accelerating/decelerating constantly at half g from Earth to the station, refueling, then hauling ass again straight to Mars
Congrats, every station needs to be 10 minutes apart and your maximum velocity is far less than a simple straight-shot to Mars. You have no understanding of how motion works in orbit, dude.

Your car analogy is flawed. Let me fix it; Imagine you have two cars, one has a top speed twice as high as the other. You're going to drive across the country, but something's different; there's no fucking friction when you aren't running your engine, so you don't slow down. The faster car accelerates to 400 km/h and coasts. The slower car accelerates to 200 km/h, then decelerates, refuels, and accelerates again, over and over, only just reaching a top speed of 200 km/h every time before slowing back down to refuel. Which one makes it across the country first? The one that's coasting at double the maximum velocity of the other, dummy.

if its nuclear what is it refueling? reaction mass? isnt there something better than that for reaction mass?
i thought liquid hydrogen was good as chemical propellant, in which case i guess it should also be loading LOX, also shouldnt it also load uranium if its nuclear?

>>11680950
>nuclear
>LH2
Looks like a nuclear thermal design. The idea is you push LH2 (or liquid methane, or water) across a running fission reactor to absorb heat and shoot it out the ass end of the spacecraft. With LH2 you get about 1000s ISP.

>>11680950
>if its nuclear what is it refueling? reaction mass?
Correct.

>isnt there something better than that for reaction mass?
>i thought liquid hydrogen was good as chemical propellant
It's useful as reaction mass for a nuclear thermal rocket because the resulting specific impulse is double that of a hydrogen+oxygen chemical engine. Which is incredibly good.

>>11680963
Speaking of which, NASA is looking at using lunar ice for ISRU which would allow hydrolox chemical or LH2 LANTR to work as moon/Gateway/LEO ferries.

>>11680963
so it doenst need to refuel uranium ever?

Could there be a sort of nuclear rocket that can use anything as reaction mass? like some sort of asteroid hopper that shoots asteroid dust?

>>11680973
>so it doenst need to refuel uranium ever?
Only as often as you need to replace fuel rods on a fission reactor, which means years of continuous operation between refueling if you have a bimodal reactor that can switch from rocket mode to electricity generation with radiators and back.

>>11680934
The gigaship just NEEDS an insultingly small canopy. Like, it has the same window design as SS, but it's just insultingly tiny compared to everything else.

>>11680973
>so it doenst need to refuel uranium ever?
The fissile material will need replacement every so often, but not nearly as often as the propellant replacement.

>Could there be a sort of nuclear rocket that can use anything as reaction mass? like some sort of asteroid hopper that shoots asteroid dust?
Yes, in theory a nuclear thermal rocket (any thermal rocket actually) can use anything that's remotely fluid-like as reaction mass. In practice, it depends on the designs of the pumps for the reaction mass. With some swapping around of the pumps, such a engine can use anything.

The website seems to be down right now, but when it's up go look at the engine list for nuclear thermal solid core. It'll explain things in more detail.
http://www.projectrho.com/public_html/rocket/

>>11680973
>so it doenst need to refuel uranium ever?

Not often, I’d imagine. Fuel rods last several years, and they’re burning constantly, whereas an NTR would only need to turn on the reactor for minutes at a time. Uranium’s decay half-life is so long that it’s simply irrelevant on human timescales, so you really only need to consider the burns.

>>11680973
>>11680991
You also get different mass flow rates and specific impulse from different fluids, and your Isp is inversely proportional to the atomic mass of your propellant, so LH2, methane, and water will be among your best bets.

Kessler syndrome is fake. Might as well discuss theology.

>>11681037
>bros how do we make sure kessler syndrome doesn't happen?
Nuke China and India until the glow is visible from the moon.

In one KSP mod, you can use NTRs with oxidizer for increased thrust but reduced ISP, in the 400’s range. Is this actually possible?

>>11681053
Yes, it's called LANTR.

>>11681053
LOx afterburner is possible but lame

>>11681053

Yes.

So does _ANYBODY_ know a single thing about this man? He's, apparently, the CEO of Blue Origin, and has been since 2017.

What the fuck is this? Why does Blue Origin's wikipedia page have only 2 references to his name, the first of which just says he's the CEO in the first paragraph and the second is the information card where it says "CEO: Bob Smith". What does he do? When I first saw somebody named Bob Smith was CEO of Blue Origin and not Bezos I thought it was a fucking prank because of his hilarious name and the fact that his media footprint is nil.

elon musk is an incel?

old space here
musk is shaping up to be a modern day howard hughes and starship will be the rocketry equivalent of the spruce goose

>>11682855
what definition of incel are you using exactly?

>>11682859
an absurdly expensive craft finished years late and at high cost by a formerly storied aerospace titan?

wilikers anon,that reminds me of something but I can't put my finger on it....

>>11682855
the man has like twelve kids

>>11682859
Unlike both Starship and SLS the spruce goose has actually flown.

>>11682859
But the spruce goose worked... it was just not built in time for it's intended function...

>>11682863
like when he says redpill he believes all that shit alpha bucks beta sux, treat women like shit and theyll like yuo, if you dont have sex its because the shape of your skull?, things like that?

>>11682870
>>11682867
>>11682865
>>11682859

if it flies in twice the itme cost three times the money and is twice expensive per launch and has half the payload as planned it will still be an incredibly uncomparable change in spaceflight technology and human history.

so no

its not like the sprunce goose

>>11682876
By 'it' you mean Starship, right?

>>11682855

it's hydrogen, anybody working with hydrogen will be dealing with hydrogen leaks until the end of time

How the fuck are NASA going to get to mars when they have only built the Orion and turned the DSH into the gateway...

Are they going to send a cryo-propulsion module up and turn gateway back into DSH later? I doubt the contractors would let them..

>>11682915
NASA has no chance of going to Mars. The funding is just not there.

>>11682914
So the leak is normal and should be an easy fix?

>>11682924
You have to remember that people care more about concepts in space flight than actual demonstrations of hardware. The funding is there, but only for researching concepts to sell like tickets to the next blockbuster sci-fi.

>>11682944

>>11682957
anarchocapitalism has nothing to do with bitcoin, anon

>>11682933
Unfortunately, the average taxpayer cares more about the concept of boots on Mars than the reality of it, and for good reason. We've cultivated a generation who haven't seen anything seriously being done in space flight. They grew up hearing about the whimsical space tales of decades past and empty promises. To them, a presentation of a possible moonbase might as well be the real thing, because they think to themselves "This could be Apollo of my time! This is amazing!". Using the way things are now money can be funneled around without any serious commitments being made. It's the perfect product. Something that takes very little of actual expenses to make, is loved by the customers, and generates billions of revenue.

The only way to fix this is to have something serious and huge happen in space flight.

>>11682952
Then what's holding them back? The core is at the test stand. Either there is something seriously wrong with the core stage that's causing the multi month delay, or they're sitting around doing nothing while being payed by taxes.

>>11682910
there was no leak
musk snorters just took a GAO report mentioning that leaks are a concern during testing the tanks and in there BO addled brain somehow interpreted that it is leaking

>>11682785
>How is it that every time I learn something new about SLS, it's about how shit it is?
Because it's a rocket project where the primary goal isn't about the rocket. Simple as.

>>11682976
>or they're sitting around doing nothing while being payed by taxes.
Yeah that's what they do, are you surprised?

>>11682976
it's the latter
I think they're testing the GSE and electronics first, and then they'll start doing tanking tests or something
basically what they're saying with the report is that the biggest thing to look out for during the test campaign is hydrogen leaks (because it's hydrogen, and they need to make sure the leakage is kept to an acceptable level)

See that might actually make the hydrolox a good choice. Replace the RS-25s with 4x Triton-LANTR and some Hall thrusters. Bam, you've got a hell of a Mars rocket without the problems of hydrogen or NTR for a first stage. Then replace the "second stage" of the SLS with solar panels, radiators, and spinny habs, and keep Orion (or Dragon 2) around as an Earth-return capsule.

>>11683063
no, replace the RS-25 with vacuum bell RS-25

>136 million dollarydoos per engine
If we're spending the price of a fucking aircraft carrier for one mission they had god damned better have an equivalent service life. "Hey let's build Shuttle engines and throw them out" is the worst of all possible uses for that money.

Why does this anon keep pushing LANTR

Just use a nuclear thermal rocket that has the materials necessary to allow it to use both water and methane. The water gets you high thrust at the same Isp as a methalox rocket. The methane gets you Isp of over 600s with a bulk density ~6.5 times better than liquid hydrogen. Launch using water, transition to methane once you're high and fast (and ideally at the same moment you've run out of water). The same overall advantages of LANTR by no hydrogen meme and you don't need to worry about having oxidizer mix with fuel where you don't want it to.

>>11683151
In this specific case it's because the SLS already exists with hydrolox tanks so it'd be reversing the "reuse existing components" trick on them. For a clean sheet design, sure.

>>11682874

Make the first stage a big fat chemical booster that gets it into orbit or most of the way there. That's why the SLS-on-SH image kicked off discussion again.

>>11683553
The technological niche for NTR in Earth launches will never exist. Industry on the moon will result in a trend towards the majority of upmass from Earth being passengers. We won't need to scrounge for efficiency, when plain old chemical propulsion can get us far beyond what will be needed. Why invite the eventual catastrophic NTR failure in atmosphere, when chemical propulsion is more than good enough?

just launch from a remote location, if the rocket is as as safe as the space shuttle (very unsafe) it would still take more than 1000 years launching every week to contaminate the atmosphere 0.5% as much as the 2000 plus nuclear test already performed

Yes, but that perspective can be twisted. Their engines are just a remake of the Fastrac. They didn't make probes. Reusable rockets haven't been proven to be economically viable (at the time). They spend their time in LEO while NASA was going to push to the moon and Mars. Landing rockets have already been done. Et cetera.

I find it incredibly hard to believe some 30 something looks at fat cat mega corporations run by accountants and administrators and goes “wow these people are truly inspiring”.

A timescale on the order of now until 2050 with new development starts for Mars components at later points of time as things like ISS ends. The moon stuff delays or vies for the same funding pool. SLS and Orion continue indefinitely and everything gets shaped around them as their fundamental contribution is never reexamined by NASA society.

That's just a projection of hypothetical planning, which doesn't really exist anymore in this pocket of "the goal is the moon", and where future events will impact what is done.

>>11683912
They calculated that they could probably do it without superheavy if they added some more engines and maybe stretched the tanks of Starship, making it more viable.
Meanwhile the noise of launching and landing still might make the whole thing impractical as the pads need to be placed too far out, so the flight time itself might be short, but the travel time may be long anyway.
Then again this is still a while away. First Starship needs to prove that it can land reliably and then it needs to prove that it‘s actually instantly reusable the way they hope.

>>11684500

Their arguments aren't sound. NASA already figured out all the transmission losses in the 1970s, and even then they were acceptable enough that you could build an entire space colonization plan around them.

Workarounds to fix even some of those losses have been solved in the intervening 40-50 years.

What exactly is your point? The type of energy production doesn't matter, any gain in efficiency will not be negated by the cost of getting it into space and maintaining it.

>>11684438
thrust support structure
it's where the actual mechanism behind those RCS nozzles is

>>11684551
>the cost of getting it into space
This is just silly in a world where Starship exists and the customer is DoD. They will literally kill people for better supply lines in combat. Spending some money on a few power sats is nothing.

>>11684465
the thrust needs to go somewhere, right?
there's a similar structure at the base of SN4, only on the outside of the skirt so you can see it

so let me be clear, even if its not reusable, or at least not right away, the moment they put one of those starships in orbit they have thoroughly cucked all of the industry, right?

>>11684577
Starship in expandable mode would be a monster that could put the entire mass of the ISS in space in go.
So yes.

>>11684563
I am just being realistic. Starship could launch for a hundred dollars per kilogram and earth based solar would still be much cheaper than the space equivalent. There may still be the odd use case for beaming power but it's not because the DoD cannot produce reliable cheap power here on earth.

>>11684577
Operational SS/SH is a catastrophe beyond measure for old space. With the somewhat pessimistic numbers we were throwing around for construction cost a few threads ago, the system is an unstoppable industry juggernaut even if fully expendable. It's looking like they could be slapping a full stack together for about the price of one SLS engine.

>>11684563
>>11684551
A multi-megawatt-scale turbine now fits on a kitchen table, and doesn't break it from weight if it's not of [cheap] Ikea make.

>>11684577
If they just managed to build these scrapships reliably and quickly, it‘ll already trump a lot of shit other companies are using. Especially if they can at least reuse Super Heavy.
Rapid reusability of both stages with in-orbit refueling is just the ultimate humiliation of the entire rest of the industry.

>>11684605
If this thing were expendable all the way it‘d give off a bunch of sea dragon vibes.
Not pressure fed. Not sea launched. Not quite as huge. But with that cheap and rapid steel construction mostly in the open, it still is in the spirit of Sea Dragon in my opinion.

>>11684636
Other companies seeking to clone it will probably wind up doing expendables at first because the one place SpaceX uses fancy materials science is inside the Raptor. It's going to be quite some time before anyone else manages a full flow staged combustion throttle/relight capable methalox engine.

How much delta V do you need to be able to do a Mars ferry run faster than just rapid firing Starships during launch windows? 100km/s? 50? Does it make sense to have a fast nukeship just for crew while the supplies take slow boats?

>>11684653
No, the Mars transfers that Starship is targeting are fast enough for crew.

>>11684636
How come people who say Starship will never fly just talk about how it won't be as cheap as everyone thinks, and not the fact that it is capable of putting 150 mT into LEO.

Even NASA admits that Starship will be able to put hundreds of tons into LEO. I don't think anyone believes Starship will never fly per se. It's just that not much criticism of Starship goes to its ability to be fucking huge, but that it might cost two or three hundred million.

So what if expendable starship costs half a billion dollars (this is a worst case scenario). It'll still put almost twice the payload of SLS into LEO for a quarter the cost.

can we report the guy who's avatarfagging with a dragon ball movie character please

You're neglecting a good portion of the operational realities of space based solar, and there's one really big one.

The power output of terrestrial solar arrays is a bell curve that follows the rotation of the Earth, and does not line up with any of the demand patterns of the grid.

The power output of a space based solar array is perfectly flat at all times.

>>11684794
the power output of a space based solar array only works when the array is above the horizon relative to the target

>>11684797
>the power output of a space based solar array only works when the array is above the horizon relative to the target

Which can be all times.

tl:dr: hop was supposed to happen today BUT because of bad weather they have delayed everything so it will only be a static fire now and a new hop date will be set later.

Do People still live in boca chica?
Of are they just playing hard for extra cash?

>>11684825
Last time I heard everyone sold, some were just let to hang around until actual orbital launches start.

>>11684814
>hop was supposed to happen today
They still don't have FAA permit so nothing was going to happen regardless

>>11684577
yes, instead of an expendable Falcon Heavy carrying like 60-ish tons at like $120m, they would have expendable Starships carrying 100-150 tons at $15-$25m a pop

>>11684308
>first stage booster
The whole point of E2E is that Starship has just enough to almost get to orbit on its own, so it's got enough to do a simple ballistic trajectory. The booster is for getting to orbit.

>>11684878
Tell that to SpaceX whose on promotional material for the project includes use of the booster.

>>11684162
They need to ask /g/ to find better stickers.

>>11684683
this
the whole starship concept is a big scam. no, starship can not fly to mars or to the moon. out of several starships only one which takes all the fuel from the other ones can - fuel that btw is the payload of the other ships.
that doesn't mean that starship won't be a great rocket. maybe it will be so great that it will revolutionize space travel and enable the colonisation of mars.
but all those "comparisons" with other rockets were starship turns out to be the best of all are just retarded

at least it's something

Except the point of the image is that the long nose tribe reveals ITSELF to be controlling the media. Elon just let it happen by accident.

>>11684734
Okay, point taken, damn.

>>11681978
Stop cooming.

>>11684162
Top section looks machine weld due to smoothness of the weld.

>>11684997
If they can land a booster on a fucking barge and reuse it, they can dock a second stage to a depot or another second stage carrying nothing but fuel. We worked out the specifics of rendezvous and docking during Gemini and have polished it since then.

>>11684997
>no, starship can not fly to mars or to the moon. out of several starships only one which takes all the fuel from the other ones can

Nice contradiction now Kys
