Space is regarded as something that a navy operates in and retro science fiction often uses 1st and 2nd world war battle techniques like shooting within line of sight, dogfights and to an extend ship classes.
It's also disconnected enough from the present to enable people to dream up less uninteresting warfare.

It's cool to spread out into the solar system. By the time we aim for the stars, we're replaced by AI long time. If this handover happens remotely peacefully (remember that there are ups and downs all-over our history ) and if we manage to somehow manifest a hand full of our best morals into their code as our legacy, I think that's when we made it. Or the other way around.

I don't know why you guys are so negative on SLS. Yes, it does have its downsides, but at least it blocked development of propellant depots for another couple of decades!

>>12146444
It's always nice to see government protecting us from risk.

>>12146444
>SLS doesn't rely on high-risk technologies
Then why is development slower than grandparent foreplay as if it were a high-risk program?

>>12146444
I seriously don't understand how propellant depots make boeing LESS money long term. If they're the ones making the depots, thats some fuckin depot makin jobs

>>12146459
Because they're reusable. Now if you somehow designed a depot that is single use you'd give shelby an orgasm.

>>12146459
>long term
Your mistake was thinking that such companies worry about long term profits over short term ones.

>>12146459
At the end of the day their business is mostly going to be coming from NASA/DOD so they can't piss off congress too much. Even Elon treads carefully talking about depots by trying to act like he's just gonna focus on tankers in the near future.

Offcourse the ignorant fuck doesnt know that the Progress spacecrafts have been doing that with the ISS since the late 1990's and the Mir since the mid 1980's.

Progress spacecraft periodicaly refuel the ISS so that the station can use its thrusters to maintain orbit altitude and adjust the orbit to avoid collisions or prepare the station to receive visitors by pushing the station to the right altitude.

Post your most difficult space flight related question and I will answer.

>>12146500
On it, but it'll take a while.

Musk said that he wants use starship for hyperfast intercontinental travel, but would that be viable? Even if manages to get 2 million/launch that still sounds too overpriced for that.

>>12146524
North American got the shuttle because Nixon was worried about unemployment in California losing him the state in 1972 but their own internal estimates from 1969 showed that a shuttle ("reusable all system") would be a waste of money for any reasonable flight rate

>Olympus feels pretty on Par with Apollo, not a real step up, but maybe that isn't even possible after Apollo.
How is the mission that pic not a step up from Apollo?

>>12146496
anon, i

>>12146545
Depends entirely on how low he can get the cost down and what passengers are willing to pay. For long haul routes (>12h flight) it might be worth it. Consider that a Starship, assuming airliner-like turnaround speeds, could fly 2-3 times on the same route in the time a single 747 could fly once. So a single Starship will have much higher throughput on the same route than a jet liner with the same number of seats. So the cost of the Starship itself can be amortized over more flights in a given space of time. Are fuel costs more important, or amortization of the airframe? Idk.

>>12146545
Musk will do whatever the fuck he wants and you're gonna like it

>>12146554
It lets you ignore ITER though which I think is the real reason for sea launch other than noise. If you're landing 100nm off the coast of China, you're technically not flying sensitive technology into China.

>>12146309
> French Navy
Thanks anon, I needed a good laugh

>>12146549
I meant the name.

>>12146559
If you're landing 100nm away from where you want to be then that just makes starship that much less cost-effective as a means of transport though

>>12146551
>Are fuel costs more important, or amortization of the airframe?
Musk said that the it costs about 900 thousand bucks of methalox per flight and the rest is for refurbishing the rocket, albeit those could be lower if it never tries to leave the atmosphere.
Still it would be like 10 thousand bucks per seat in the best case scenario.

>>12146580
I actually looked it up and a flight from NY to Beijing is about 800 dollars on average, so honestly I don't really see starship being used that much by civilians.
Agree with you that the US military would be all over it, especially since a bunch of the military-industrial complex shills are bitching about how the military is "underfunded" and needs more money as of late.

The 2 million dollar mark was for a full SH/SS stack going to space. I believe that last we heard the point to point flights were planned to skip SH entirely and just use the Starship itself. That should cut propellant costs by at least 60-75%, not to mention the opportunity costs of keeping your SH boosters around for orbital flights.

Add in the fact that point to point is expecting close to 1000 passengers per flight, you're looking at sub-$1000 costs per passenger (although assume a big profit margin). Even at $3-5k that would be an absurdly good deal for anyone doing business overseas.

I'd imagine that if we're talking SSTO, it becomes much easier to design a purpose built SS just for E2E flights. Stretched tanks, 4-6 sea level Raptors with no vacuums, thinner/no heat shield, etc. As much as they probably want to start out with a common design, long term they could probably get way more payload with a little tweaking.

The Small Nuclear Rocket Engine, or SNRE, was designed at the Los Alamos National Laboratory (LANL) for upper stage use, both on uncrewed launchers as well as the Space Shuttle. It featured a split-nozzle that could be rotated to the side, allowing it to take up less room in the Shuttle cargo bay. The design provided 73 kN of thrust and operated at a specific impulse of 875 seconds (8.58 kN·s/kg), and it was planned to increase this to 975 seconds, achieving a mass fraction of about 0.74, comparing with 0.86 for the SSME

Loading should be easy since the entire nosecone is designed to be loaded inside a clean room and then craned up and attached to the ship itself (source is the official Starship User Guide). They can have a dozen nosecones preloaded with whatever gear the military guys need ready to go at the launch site, the problem is that once it lands its going need to be unloaded bit by bit. Unless of course the ship itself isn't planning to do a return flight in which case I guess they could crane the nose off at the landing site.

we've got a couple getting built but i think the plan is to retire a nimitz for every ford that gets built and we're gonna stay at 11 for the foreseeable future

>>12147059
I'm guessing that by the late 2020s we'll have a handful of space ports off the coasts of major cities like NYC, LA, London and Beijing and we'll see E2E flights mainly for the rich and business types. Early 2030s once the concept is proven out is when I'd expect to start seeing the concept expand and become economical for more traditional civilian travel.

I really hope that once reliability is proven out that they can start getting approval for more overland routes. I don't know how the hell a NY-Cali route is supposed to work out if the ship is forced to only launch over water.

>>12147279
>will you have mountain dew during the call today?
>of course
God bless

>>12147276
Explain how the fuck they do three launches a day of the ship needs to get picked up and moved to a different location.

I guess I shouldn't have said the nosecone itself will be removable because we don't know that for sure yet. The payload is so they may have some rube goldberg device to shove the payload in from the side. Nosecone seems a lot simpler if they can figure out how to reliable connect the header tanks.

>>12147285
>I don't know how the hell a NY-Cali route is supposed to work out if the ship is forced to only launch over water.
If it is just one stage like Musk said, then it could be launched over land, I think.

>>12147279
Personally idgaf which part of the moon NASA lands people as long as they actually land people

>>12147283
>built but i think the plan is to retire a nimitz for every ford that gets built
Ahh that makes sense.

>>12147292
explain how the fuck they do three launches a day if they're taking the fucking front off every time
I think three launches a day is for tanker launches, and that only works if you're filling up three different spacecraft in three different orbits going to three different places
although I guess you could have one for Luna, one for Mars, and as many as you like for geostationary...

>>12147293
it'd still cause a sonic boom

>>12147293
Currently I'm pretty sure that no rocket is allowed to cross over land until its up to a certain altitude in case of a RUD. Since an SSTSO Starship is going to be right on the bounds of feasibility I'm assuming they don't want to waste a bunch of dV fighting gravity at the beginning of the flight.

>>12147285
>I don't know how the hell a NY-Cali route is supposed to work out if the ship is forced to only launch over water.
Go the long way. Still probably faster than flying.

>>12147298
>explain how the fuck they do three launches a day if they're taking the fucking front off every time

easy, by building thousands of starships so every major city on the planet can be readying 8 for launch simultaneously

>>12147307
three launches per Starship, anon
of course you can do three launches in a day if you've got ten Starships in the payload processing queue

>>12147298
It's a whole lot easier to truck out a new nosecone/payload adapter from the clean room, crane it up and connect it on than to move the whole ship the other direction to do the same thing. As long as the payload is airtight outside the clean room it shouldn't matter where they actually attach it to the ship. Hell they could have a row of payloads outside next to the landing/launch site waiting for the next ship to land so that they can attach it while it refuels.

>>12147302
It doesn't have the range to go the long way. At that point you're just below orbital speeds.

>>12147307
Each ship is supposed to be able to do three launches a day.

>>12147311
do you even need a clean room if it's just a suborbital hop and the cargo's gonna be unloaded in a couple of hours max?

Has anyone made an Electron-type orbital launch vehicle in RSS/RO?

>>12147311
you need to do that anyway in order to clear the landing pad for the next Starship coming in and to do any necessary work on the heatshield/engines/avionics that needs to happen
>>12147315
no, we're talking about satellites here

>>12147316
ROEngines has the rutherford in it

>>12147297
Yeah the Nimitz class is 45 years old now, so with class lifespans generally lasting 50-60 years they're getting up there for capital ships. It's good to start phasing them out a bit before they actually start to hit the wall, forces manufacturers and congress to actually commit to replacing them and it gives us some extra time to iron out the technological kinks before they actually have to hit the field and stand alone.

>>12147316
I've tried building scout in RO but it has awful center-of-mass issues after you drop the first stage and I never got it working.

>>12147323
Wonder if Elon could buy denuked aircraft carrier from the USN to land StarShip on.

>>12147352

>>12147352
>yeah bro just rip out the entire engineering spaces and reengine it with turbines
>no nobody's ever done that before
>what do you mean an oil rig is infinitely easier and cheaper

>>12147358
>>12147356
No shit, as floating hulks just to land on. Looks like JFK, Kitty Hawk, and two Tarawa classes are still around and non nuclear.

>>12147352
Probably not worth, in spite of how fucking cool it would be. Even without the atomic powerplant a US carrier is a goliath military ship, the hull alone would probably be hundreds of millions of dollars of investment, refurbishing it and replacing the powerplants would likely be almost as much as a new vehicle, and of course moving that giant fuck anywhere with a diesel-electric powerplant is going to run you as much as running a cruise liner.
If I were going to get a dedicated giant rocket catcher I'd probably buy old oil or cargo tankers instead. They can also be extremely wide and would cost less to operate and modify for purpose.
A static platform as >>12147358 points out will be much simpler and much much cheaper though. Turnaround time will be slower from a platform, but if you have multiple reusable boosters you can work the schedule to set up uninterrupted continuous launches as long as you have payload vehicles and as long as the boosters hold out.

Tried that, still fucked. I'm thinking now the problem is with the fucking collision clipping between the hollow structural shells from near future exploration and the procedural tanks I have inside them, so time to rebuild it for the third time and see if I can figure out a less janky way to attach everything together and reduce the size of the internal tanks a bit in case they are clipping with the outer walls.
I've launched flyby probes to Ceres and Jupiter and an orbiter to Venus while trying to fix it, and as long as they have fuel to keep RCS going constantly when they are active they are perfectly controllable so they should be alright for now

speculation(?) on labpadre stream

what pressure would 7.1 have to hit before it could go cold gas ssto?

Scientifically speaking, what is the ideal number of legs for a lander?

>>12147575
3 is always the most stable but maybe not doable for larger craft.

>>12147575
0, aerospike butt landings

As the max pressure of the tanks increases will that just translate to an increased safety margin or will they use it to increase fuel density?

>>12147497
Why are they using zoom?

>>12147578
incorrect, more legs is more better

So NASA released the full Artemis plan and no one posted it? You're slacking, /sfg/

https://www.nasa.gov/sites/default/files/atoms/files/artemis_plan-20200921.pdf

i’m a brainlet but i watched a big video on how starship should work and there’s one thing that wasn’t mentioned that i was wondering if you guys knew about.

instead of just sending one starship up and refueling it, send up some tankers along with it to get filled and stick by it for the ride to provide more fuel. i get that this would probably be less efficient than just one bigger spacecraft but this would only use hardware currently in development. i’m pretty sure you could get a decently pig payload to the outer planets this way, at least i don’t see why not. is this feasible? and if so has it been mentioned?

Artemis will happen for sure if Trump is reelected and probably/maybe at least to Artemis III if Harris is elected. It probably won't be on schedule, but its legally required to proceed.

I will launch a rideshare satellite on an intercept trajectory with the orion capsule on artemis II. There will never be americans near the moon ever again.

yeah, literally the same tankers spacex is developing to launch on a super heavy and fill up the cargo and crewed starships once they get up to orbit for the trip to mars. i’m saying if you kept a couple of those tankers up there and filled them up they could travel with the other ships and act as an external fuel tank, giving them more delta v. pretty sure that doing this would mean you could be getting missions (either manned or much larger unmanned than previously possible) out to the whole belt and out planets past it on just the currently under development starship architecture.

and yeah it would take more launches so it’s operating under the assumption that starship really does mean far reduced launch costs, and if it does i’m pretty sure this would be a way to do missions that just a starship loaded with fuel in orbit couldn’t do.

There’s no argument to be had. Printing a habitat will remain a stupid idea for decades to come.

Yeah. Do you think 3D printing will be a big deal when we return to the Moon for artemis (and eventually go to Mars?) There are so many schizos here on /sfg/ who are convinced that printing is the future- that it will be used for EVERYTHING. This is objectively wrong because 3D printing tech sucks in its current form. It’s basically still in its infancy. No way you can print habitats and rovers and complex parts. Yet some anons are gay and are convinced otherwise
