is thatthe SLS?

Hear me out, lads:
We start a "UFO cult," a religion, which believes that we can meet our gods in space. Then we build a massive rocket.
Because we're a religion we don't have to pay certain taxes making the cost of launch slightly cheaper. We can acquire land cheaper. We can weasel ourselves around certain labor laws. And we can weasel ourselves around laws concerning who we can or cannot include (racially, sex, etc.).

honestly idk. i think it's just spacex stans overcorrecting to avoid looking like sls haters. NSF is notorious for this, but a surprising number of famous spacex stans fall into this trap. they think it makes them appear more enlightened and "balanced"

>>14773914
I've seen many people do that, r*ddit does it too (inb4 go back), they are basically spacex/musk fans trying not to act like spacex/musk fans, as if it were taboo or something. Just say you like spacex and everything else is shit, why is it so hard expressing oneself?

>>14773618

I'd reccomend you guys take a look at the Orion's Arm website.

I'm dropping this link for anyone interested in space colonization ideas. Keep in mind it's a little on the hippy side regarding social aspects (I.E. David Brin's Uplift series, democracy=good, some Culture wankery), but there's stuff ranging from low-gravity adaptation to future foods to solar habitation. Isaac Arthur is a member on the site, but only mentioned it once. Pretty good source of worldbuilding data. Kinda disapointed there's no article on mass drivers.

I'd actually post links, but the bots are retarded.

>>14773933
Do you want to imagine the future or build it?

Here's Orion's Arm's boostbeam system; a concentrated laser hits a solar sail and accelerates a target to a fraction of c.

Imagine that Avatar's ISV Venture Star is the target it's aiming at.

>>14773935
The former, obviously, but speculation helps with a possible general outline.

Change pic related from Tel Aviv to the Moon, because in order to expand out, we need an industrial world that can manufacture infrastructure, then deliver it to orbit cheaply.

Not until ICBMs are themselves obsoleted by orbital laser grids or brilliant pebbles. Expertise must be actively maintained or it degrades.

>>14774067
I would be happier if they spent the same amount of money just building ICBMs and launching them into the pacific as a training exercise ever year, rather than trying to attached them to orbital launch vehicles.

>>14773812
ICBMs are the reason we have spaceflight in the first place, until the ICBM goes out of use it'll remain a huge part of LV development.

https://arstechnica.com/science/2022/08/rocket-report-europe-wants-a-super-heavy-lifter-starship-nets-launch-contract/

>The ITT is aimed at procuring the preparatory activities for European heavy lift launcher (PROTEIN) architecture Phase 0/A analysis. This analysis has as purpose to develop an adapted and more performant transport means to accommodate large space infrastructures (e.g. space based solar power, space data centre, etc.) and deep space missions. It is foreseen that after 2035, with the European Green Deal initiative, current European launch vehicles will not be able to transport large payloads with the necessary cadence. The present PROTEIN activity will propose a preliminary European Heavy Lift Launcher (EHLL) architecture in order to foresee delivering of at least 10 000 t per year to space.

Europe wants a rocket that can put space based solar power into orbit.

>>14774089
>Euros want a huge protein rocket
So are they trying to be as gay as possible or does it just come naturally to them?

>>14774084
Only in the sense of keeping industry to produce large solid rocket motors healthy, its the reason both the STS and SLS use(d) big solid boosters instead of liquid boosters despite the performance difference.

>>14774069
but muh heckin testban treaterinos!

>>14774094
It's Europe, so probably a bit of both.

>>14774089
What is the cost per unit of electricity in the recent ESA space solar?

>>14774098
Well the only other option for ICBMs is hypergolic liquids and I would rather those not be used for the environmental impact.
At least with solids you get viable orbital boosters out of them and with hydrolox's terrible sea level thrust it makes sense to use solids on a hydrolox core.

>>14774049

>>14774098
>Only in the sense of keeping industry to produce large solid rocket motors healthy, its the reason both the STS and SLS use(d) big solid boosters instead of liquid boosters despite the performance difference.
What actually is the performance difference? I haven't seen graphs or charts of it in a long while.

>>14774107
Nontoxic hypergolic propellant is an option

>>14774114
Play some KSP RP-1, if you don't end up building a booster-sustainer for the low cost performance boost you are a fool.
The Titan 2 / 3 is a perfect example of throwing big solids on something to drastically increase payload to LEO without needing to develop a new liquid engine at great cost.

>>14774116
I have never heard of this, what are non-toxic hypergolics?

>>14774121
IDK, Impulse Space is using ethane and nitrous oxide

>>14774115
It's in the rocket equation. Shuttle/SLS SRBs have an Isp of 242s. The F-1 (NASA wanted to use the F-1B for SLS) was 263s at sea level rising to 304s in vacuum. Solids are only cheaper if you're expending the stage, which is why Vulcan has SRBs but Falcon Heavy recovers the side boosters most of the time.

>>14774160
I'd prefer payload information since the F-1 is not a particularly high performance engine.

>>14774121
>>14774139
IIRC ethane or propane and nitrous oxide only make sense for reusable spacecraft since you need a silver catalyst to break up the nitrous and enable combustion. Hydrazine/NTO also has an absurdly low freezing point so it's more militarily useful against the Russians.

>>14774160
>They could have had a kerologgs SLS
This is a great crime

>>14774169
Congress asked for a new super heavy lift rocket. NASA wanted to build a Saturn VI. 3STO, kerolox-hydrolox-hydrolox, improved versions of the F-1 and J-2. Congress threw a fit because all their heckin contractorinos they'd spread out across 300+ districts during the shuttle program would have been out of jobs and put language in the bill requiring them to use shuttle parts. So here we are.

Starship update when?

>>14773887
we're not bringing children to mars you psycho

>>14773933
>democracy not good
would you all please move to Saudi Arabia already

>>14774106
Some rough guesswork:

say orbital cost 1500€/kg (I think doable with a big production line, even without reusability, solar panel cost included), 30W/kg for the solar panels (converter and transmitter included, iRosa has a higher watt/kg), and portion of orbit in sun at 95% (geostationary) and power beaming efficiency 60%

This would result in a fixed cost of 87,8€/watt
One watt over 20 years-> 175.2kWh, so in total 50c/kWh

I pay this much rn in Austria

>>14774436
you vill pay 10x what you should and you vill be happy

>>14774436
power beaming from GEO is not close to 60 percent efficient and you didn't account for the receiving station cost.

>>14774436
Which btw would require about 13 million tons to GEO, for wich you need like 500 million tons of total propellant and roughly the amount of lng Europe uses in per year.

>>14774491
Quick googling showed me even bigger numbers for microwave beaming, do you have a better estimate?

Also my assumption was that everything on earth is going to be very cheap when compared to anything in orbit, so I just ignored it (It's just a rough guess with some numbers behind it, don't read too deep into it)

>>14773651
I always imagined the two headed guy to be deformed in other ways

I started reading the ESA space solar reports. I'm going to read with an open mind, without casey hijacking my brain.

>>14774553
Current electricity generation in Europa is 4000 TWh
https://www.statista.com/topics/8491/electricity-in-europe/#dossierKeyfigures
The report says "Potential for
800 TWh
per year by 2050 to
contribute to Net Zero"
This is already a failure.

>>14774563

Here's a rule of Thumb while reading these reports -
10 TWh per year is the same as 1GW

>>14774553
> provide an alternative to nuclear power
so to summarize, we are undertaking this giant project because people have unjustifiable fear

>>14774563
Holy moly, these consultant reports are full of fluff.
Can someone just tell me
1) What is the GW of a single satellite and how much it would cost
2) How heavy it will be

>But the arrays being studied today are far too expensive to be used routinely for DSN things.
why

>>14774614

>>14774732
Because the proposed arrays are huge. SKA 1 will have 200 dishes and many thousands of low frequency antennas, ngVLA will have about 250 dishes. For refernece the VLA only has 27, and even it is hardly ever used for DSN purposes..SKA 1 will come first at a cost of over 2 billion, ngVLA is currently projected to be about the same but it's timeline is much less certain.
The other point is that NSF will foot the bill for ngVLA with international partners. Not NASA.

>>14774636
space based solar for earth seem to be headed for conflict with thousand+ comsat constellations

Could Russia unhook Zvezda-oneesan and Nauka-chan and make a ROSS out of the ROS?

(I didn't mention Zarya since it is US-owned)

>>14775013
ROSS is polar, ISS is 53
Also Russia has said ROS is getting too old, thats the reason for building ROSS in the first place

Hi /sfg/ I was wondering if we could crowdfund purchase of L2? The lifetime license costs $199, so if each one of us pitches in $1 we could get one.
Would be difficult to coordinate though

>>14775018
Let's assume they keep 50-something degrees.

>>14775020
Never mind, the 2 month only costs $19.
If someone downloads everything and spins up a torrent.

>>14774874
comsats that get in the way WILL be vaporized

>>14775020
Are you going to charge NASA rent or what?

>>14774424
Of course not, that'd be wasted mass. You make the kids when you get there, dummy.

>>14774874
Not really, it would probably be put in geostationary orbit so no risk of a direct collision. Satellites would need to have some method of propulsion as to not eventually fly into the beam but a plane change maneuver to dodge it would cost a negligible amount of delta-v.
>>14774636
The cities will be burnt down before the first panel is ever launched. In all seriousness, blackouts are a temporary issue stemming from lack of investment, SBPS has that same obstacle but it's much worse because it has no chance of being profitable. A better project would be SBPS for the Moon as that would compete very well against nuclear and ground based solar which would need a ton of energy storage unless it's put on a peak of eternal light.

>>14775029
is a credit/debit card required for the purchase

I have an idea where heat from nuclear reactions would be somehow used to make electricity, much simpler than SBSP and also green

>>14774749
you can clearly see the cooling channels in the nozzle and all the plumbing, the combustion chamber has an unconventional design though

>>14775027
Hypothetically they could attach a tug and move it anywhere they wanted, in reality the dV for that is prohibitive.
LEO tugs is the NERVA usecase that makes the most sense but first you need 2 destinations you are moving lots of stuff between, hopefully the moon fills that role one day.

Does anyone know why Europe, full of self-avowed super geniuses and enlightened people, have so far failed to compete with the Falcon 9 despite it being the bare minimum pencil dick rocket? It's been flying for over twelve years. Hell, even expendable F9 made money.

>>14775079
It's harder due to competing national interests and such. Call the US fractured or contentions, but Montana or New York isn't going to throw a hammer to NASA contracting SpaceX because they have no business operations in their states. In EU that will happen.

>>14775071
The real killer for SBSP is that replacing the rectenna array with a solar farm of equal size gets you more electricity at a fraction of the cost.

>>14775066
how else do you pay on the internet?

>>14775086
The ESA is NASA is every project was run like it was SLS

does anyone know why the US, full of super geniuses and inventors, has to far failed to compete with the Saturn V despite it being a speed built hunk of metal? it's been flown over 50 years ago. Hell, they even have the blueprints

>>14775093
rest assured, ESA has had a meeting and determined the way to compete in this new era of space exploration is to increase the amount of rules and regulations.

>t. Texan

>>14775079
because they're too busy building particle accelerators and totally monopolizing the market on EUV Lithography for the entire planet

>>14775098
They didn't have the politcal will for major projects or the commercial / military requirement to put 140 tons into LEO. SLS is the replacement and even the block 2 will only get 130 tons to LEO.
If you are a clap convince people you know space is important, if you aren't a clap then why do you care?

>>14775110
That's hyperbole. Ofc a plenty of hobos starve and freeze to death in the US every winter. The ultimate impact isn't gonna be any worse than that.

>>14775107
Compared to the cost of building out huge solar arrays in geostationary orbit? No, storage doesn't have any significant costs.

>>14775115
space is a retarded dick measuring contest and always has been

building cutting edge lithography machines is actually profitable

>>14775117
I think he's referring to the terminally expensive natural gas germans are expected to pay for now.
Hobos freezing in winter is pretty normal, regular people freezing in their homes because they can't afford to heat them, that would be fairly alarming.

>>14775110
The Soviets had a lot of very smart people, but that didn't really translate to the well-being of the average comrade.

>>14775078
>they could attach a tug and move it anywhere they wanted, in reality the dV for that is prohibitive.
Lets say we keep the inclination and just change the perigee/apogee just enough to stay clear of the USOS' orbit.
Zvezda has buil in propulsion, so it should be able to.
But my question is, how feasible is to undock and fly away, from the electric, systems and interconnections point of view.

>>14775165
It's not. Zvezda was not connected in a way that would make disconnecting it later in any way practical. It's probably one of the most through module connections on the whole station.

>>14775018
>ROSS is polar
Sun-synchronous orbit, so near-polar, if you'll forgive me for being a bit pedantic.
>>14775089
Solar panels tuned to wavelength of a incoming laser beam could achieve an efficiency of ~70% and of course you can beam much more power per square meter than what comes naturally from the Sun. Overall though, yeah, less efficient but for future generations with much greater power demand Earth-SBSP could be attractive.
>>14775078
Due to the cost, there is no use case for nuclear tugs in cislunar space unless it performs a task that literally cannot be done by chemical or solar electric propulsion. Such a task doesn't exist in the civilian world, even the 70 degree inclination change someone suggested to move the Russian ISS modules could be done by chemical, after raising greatly increasing its apogee since that overall would cheaper.

Career tracking for kerbalnauts, if somebody is the first into orbit they should get a little medal or something, some recognition for continuity's sake if you're playing a career.

If past is any guide then while German strategy might be misguided, their tactics and adaptability is unmatched.

>>14774121
any hydrocarbon is hypergolic with HTP. HTP is more of a pain in the ass to handle than toxic hypergolics in some ways but it won't poison you.

>>14775189
Maybe there is already a mod for this but I want a maneuver node planner that can account for the low but persistent thrust of ion drives. I also hope the development effort didn't get sidetracked by all the interstellar travel meme bullshit at the expense of what should be the core game but I'm a open hater of stock KSP and I think it should be like RO/RP-1

>>14775079
Because Europe is not a country. It's +40 different countries with entirely different lamguages, cultures and priorities. You can't poll all the capability and human capital in one place and interests will be entirely different making it impossible to fund any large scale risky project.

Kind of, it's too inaccurate for what I'm trying to use it for. I have been fighting Deimos orbit lately (RP-1) and floating point errors make it near unplayable with inaccurate burns making it fully unplayable.

>Timewarp during burn
There is a mod called persistent thrust that allows you to do it at faster warp speed but I can't expect the average person to fuck around with that. Everything he listed should be in the stock game, including something that serves the same function as MechJeb.

>totally monopolizing the market on EUV Lithography for the entire planet
Over the course of EUV development, ASML spent decades sucking down money from the US DOE, Intel, Samsung, and TSMC. Europeans were too short sighted and risk averse to invest in indigenous tech research, and now ASML is only European in name. When it comes to influencing ASML's international trade, The Pacific Rim and the US have more sway than Europe.

>>14775276
Just as bad. Also, there's the problem that Russia doesn't have nearly the money they'd need to make that purchase. The only time NASA would even consider it would be at the end of the ISS's operational life, and at that Roscosmos isn't even 100% sure that the ROS can make it to 2029 without a catastrophic hardware failure. There are some very solid reasons why ROSS is planned to be made of all new components while Nauka got shipped up to the ISS rather than reserved for use on a Russian station.

>>14775317
Falcon 1 was insanely fast, Falcon 9 was pretty fast, Falcon Heavy was near oldspace speeds, Starship is oldspace speeds.

-The 5 segment solid boosters that SLS Block 1 and Block 1B use produce 6.5 million pounds of thrust. The four F-1B engines of the SLS boosters would produce 7.2 million pounds of thrust.

-The 5 segment solid boosters have an ISP of 269 seconds. The F-1B has an ISP of 272 seconds.

The improved thrust and ISP would have allowed SLS to lift 150 tons to LEO instead of the 130 tons of the Block 2, would allow the boosters to throttle and would not suffer from the combustion instability caused vibrations that cost SLS the Europa Clipper launch.

Lmao, delusional. They haven't built a working commercial reactor in 34 years. Construction on Flamanville 3 started in 2007, it's now grossly delayed, overbudget, and when finished it will only add 1.6 GW to the grid. Macron did announce they'll build 6-14 new reactors by 2050, but it's not nearly enough to replace all the ones that will by offline by then, since most of their 56 operational reactors were built in the 1980s.

EDF was over 40 billion euros in debt before it was nationalized recently. Now high renewables production fucks the French taxpayer even harder, as the plants would either be selling energy at a loss much of the time or operating in load-following mode, but both make them more uneconomical to run. Nuclear paypiggies.

That is true of literality whatever you chose to balance demand, be it coal, gas, nuclear, storage or excess renewables. That's not a cost of nuclear, it is the cost of renewables being intermittent.
>Nuclear paypiggies.

>Another spiral galaxy, also at z = 0.7, again highlighting JWST’s ability to resolve small-scale features even for modestly distant galaxies.

I don't know if this has been posted, but JP Aerospace (the crazy airship guys) have been making progress on MHD boosted electrochemical rocket engines. This is super cool because MHD augmentation is basically the only path to better high thrust rockets without an onboard nuclear reactor or beamed laser-thermal, neither of which should be used in Earth's atmosphere.

>>14775983
Rocket engine flames are partially ionic. Inject some potassium in there for more ions and run the exhaust through a set of electrodes and magnets to grab it by the ions and make it faster. Same mdot plus more Ve equals higher thrust and Isp, so it's a much more powerful engine. You can also run the MHD in reverse to extract electric power from the engine at the expense of thrust.

>That is true of literality whatever you chose to balance demand
To a point but it's more impactful to nuclear because of its incredibly high capital cost and long return on investment, versus say a natural gas plant which has a much lower LCOE and most of the operating expense is in fuel. If this is all the support that nuclear gets during a large but temporary energy crisis, the uncertainty has favored renewables most of all. Don't look to the government to solve energy independence, if you want it, get a solar array and battery.

>ignoring Belgium and Switzerland

Am I crazy for thinking that everything Musk invests in is ultimately meant for Mars? Electric cars, combustion engines don't work without an atmosphere. Boring Company? Why would he randomly invest in big drills, unless it's to dig underground habitats on Mars? Vacuum tube trains are retarded on Earth, but Mars barely has an atmosphere to begin with, so they would be much easier to implement there. The downside is that he has to somehow try to sell those ideas on Earth as well, but I feel like all the work on Earth is just R&D for Mars. Has anyone probed Musk on this?

>>14776038
Not building nuclear powerplants make sense for very small countries like Switzerland and Belgium.
Switzerland doesn't have much space to build on, they even built a powerplant once but they made the mistake of listening to the general public, and so the entire thing became a money sink.

Germany has no excuse as they have 83 million people and a massive chunk of land to build them on. Instead their green party (which at this point should be classified as domestic terrorists) decided to shut down any remaining powerplants and turn on coal plants instead

>>14776047
>Has anyone probed Musk on this?
He's explicitly stated it multiple times. He's a longtermist, the goal is to maximize the number of living human beings in the universe, and to avoid extinction. The best way to do this is to make mankind multiplantary as quickly as possible. Read Bostrom.

It's also why he has so many kids.

>>14776047
You are far from the first person to believe that.

>>14776054
>He's explicitly stated it multiple times
Oh, I'm out of the loop then. I imagined he wouldn't want to state that all this garbage is actually meant for Mars because it would kinda push away investors if that stuff isn't useful on Earth. But yeah he seems like a Mars colony is all he works towards, and all these different companies seem like they fit the bill for that perfectly

That's why they should build nuclear. It's very very dense in terms of land area used for power generated.

>>14776057
>if that stuff isn't useful on Earth
Well, it's tangentially for Mars. Tesla is also explicitly to reduce emissions, and to fund SpaceX. "Mars" itself is a simplification, the point is to secure the future of mankind, Mars is not an end in itself. He founded OpenAI to work on AI alignment research, Tesla for cashflow / climate change / etc, SolarCity he purchased to reduce climate change. I have no idea what Boring company is for, maybe he'll actually put a huge drill on Mars at some point, but that seems strangely far away for it to be the only reason.

You'll see more effective altruism / longtermist stuff in the next decade. Musk is aligned explicitly with that group, if you want to read more.

>I want to do everything we can to maximize the use of technology to help achieve a better future for humanity. To that end, any area that contributes to a sustainable future is worthy of our investment. Whether it's Tesla, Neuralink, or SpaceX, these companies were all founded with the ultimate goal of enhancing the future of human life and creating as much practical value for the world as possible—Tesla to accelerate the world's transition to sustainable energy, Neuralink for medical rehabilitation, SpaceX for making interstellar connections possible.

There's more, too. Nuclear in Germany was such a shitshow often enough. Sure some of the existing plants did a decent job. Apart from the fact that there will never be long-term storage for their waste within German borders.
A lot of the German distrust of the nuclear industry has been well earned. Too many cocky managers and politicians trying to rush projects with false claims that crumbled under the slightest scrutiny.

>>14775331

>>14776746
>Making the pump is surprisingly cheap actually, mostly 3D printed aluminum with some CNC'd parts, I would say < $2000 for this size.
My nigger I do not have 2k to drop on a pump for a liquid rocket.

>>14776741
>>14776743
Having all the money in the world doesn't mean shit without a solid background in fluid dynamics, thermal dynamics and mechanical engineering. What makes it impressive is even the smallest pro team will have one guy doing the pump, another doing the regenerative cooling and a 3rd doing the injector head / combustion chamber.

>>14776753
Yeah, I'm just saying, I've prototyped stuff (unrelated to rockets) on a smaller scale, and the main reason I wouldn't consider something this size is cost. I don't have the skills, and this is an amazing accomplishment, but it is not
>Dude just pirate solidworks and send the files to a CNC mill bing bang boom people underestimate how easy it is

>you will never build a functioning liquid rocket out of two commercial-grade dewar tanks, a GG turbopump you made yourself, and a powerhead you printed based on some frames you grabbed from a Youtube video

why live

>Starship is oldspace speeds
You don't even know the meaning of "oldspace speeds".
Come back when they've spent 2 and a half decades modeling Starship.

>Starship has two years to launch a couple thousand satellites

wew

Delta III

>>14776792
>Starship has 2 years to make 100 launches

>>14776792
it could do that in a week or two

I didn't notice this was a crossboard link at first and got all excited, thinking /sci/ had gotten flags.
Honestly I'd be cool with /sfg/ alone getting flags so we could more easily identify seething yuros and chinamen.

>>14776792
>implying the US government has more power than US corporations
It's going to cost him some political donations and maybe even a new Tesla factory somewhere but there is no way the FCC fucks with Starlink in any way that matters.

>>14776844
>I use imageboards to judge people by something other than their posts
Why are you even here? The entire rest of the internet has join dates, post counts, user name and karma if you want to judge people on anything other than their words.

>>14776792
Tintin A and B launched just four years ago, and now Spacex operates the majority of active satellites in orbit.

>>14776851
Flags engender a richer shitposting environment

>>14776793
they should make a delta iv even bigger

>>14776859
They should make the Delta V just for the "who's on first" conversations that would happen trying to design the thing.

Delta V is Vulcan (Delta Vulcan)

Can someone repost the image of the blue haired vampire girl about to board the rocket?

>>14776964
blue haired?

>>14776846
DoD wants Starlink fully operational across the globe. Once Orange Rogget launches. The Starship program will go to plaid.

>>14776969
Yes that is the girl. But the image I'm looking for is a drawing, not a screenshot.
She was about to board the rocket. Her helmet was off and there were other workers around the boarding gantry.

>>14777002
interesting...i dont recall

>>14777002

>>14777002
For real though

>>14777023
oh yeh i remember now. are there any more like this? really cool

>>14776792
Falcon 9 launched 2500+ in ~2 years.

Gen2 sats weighs ~1250 kg.
X 100 = 125 Ton
x 25 launches per year = 2500 in 1 year.
x 50 launches per year = 5000 in 1 year
x 100 launches per year = 10000 in 1 year

50 launches per year is ever 1 Starship launch per week. This moderate run rate is something F9 already does today.

>>14777025
Spaceflight art? Plenty.

>>14777023
Thank you anon.

the amount of engineering and practical knowledge across various different fields needed to do what this guy did is absurd, you need to know fluid dynamics, machining, mechanical engineering, control engineering, electrical and electronic engineering probably, metallurgy, and probably a shit ton of other things that im forgetting. idk how a fucking undergraduate would have that much knowledge and experience to build an actual liquid fuel pump fed rocket engine on his own. insane

>>14777060
Oh yeah, I forgot the Apollo tour bus goes right past the VAB/the SLC 39 access road

Rocket design peaked with the Saturn V. Fight me.

what will the spacex fuel depot look like? it takes multiple starships to fill up a single starship, so if it's going to fill up HLS then it'd have to be huge.

>>14777096
No, why?

>>14777097
what?

>>14777094
Imagine a Saturn VI that used RS-25s for the upper stages.

>>14777096
In the interest of parts commonality it will be a Starship with no re-entry hardware and stretched LOX and LCH4 tanks to fill its payload space, with a docking port for fuel transfer plus whatever they've got cooked up for making that fuel transfer work in both directions

Since it's basically going to be a super-starship it'll be very interesting to see what they do with something that has that kind of delta-v in the future

>>14777104
First, you must imagine an RS-25 that can ignite in flight.
Piece of shit.

Is there a /dsg/? Deep sea general?

Victor Vescovo discovers USS Johnston, deepest wreck dive in history

>>14777105
i thought you need something like 10 starships to refuel a single starship? if so then the depot would be 10 times the size of a starship.

>>14775774
Yes NSF has a paypal option.
Pls someone download everything off L2 and spin up a torrent, I'll seed it forever.

>>14777117
You need 10 starship launches to refuel a starship because of the rocket equation - the tanker flights burn propellant on the way up. The actual mass of propellant required to refuel a starship in orbit is equal to what starship holds on the pad.

>>14777117
I haven't done the numbers on any of this

A tanker would be a fuel depot with the required re-entry hardware and would have to reserve some fuel for landing. The margin for reaching LEO and landing must be quite large if they're citing dozens of launches though, or maybe they're just going to skip the tanker step and just install a refueling adapter plus some tanks in the payload bay of a normal starship

>>14777117
Anon.. where do I begin?
Why should it be 10 times the size of starship if it will only refuel one starship?

>>14777124
Why is it that 78 years since V2 reached space, we are still using chemical rockets?
There are missions which require Starship to be refilled in GTO (for deep space missions). This will require 70+ launches. Too much!

>>14777128
spinlaunch will save us

Blame the judenphysicke that prevented us from attempting to build aether sails (QI thrusters) for a century.

I mean Sammy B, they discovered Johnston before that

>>14777141
Why does this dive seem like a big LARP? like they never needed to send a guy down there, it's not like they're planning to do an EVA or anything. did the goofy guy in the red cap pay to go down there just to break some arbitrary record? he talks on the radio like a tard

>>14777156
goofy guy owns the whole thing
Hmm I did wonder the same thing, but is robotic exploration possible at 6000m+? I think it would be difficult to get a live video feed to remotely control ?
They didn't know the exact position, so had to follow the trail of debris

>>14777174
btw he's the guy who was in new shepard recently
quite an adventurous life if you read his wiki

i still dont understand how starship could lose to sls after it failed the green run and failed the WDR (multiple times)
