It is tragic. In all these situations, and they are absolutely rife, I wish we could just pay off the beak dippers and go do something good with the remainder rather than having to go through this charade or pretending that all that money and jobs are required. The end result would be better

I usually like mocking the brits as an exiled convict but fuck that was the dumbest deal.
I get you want your own gps constellation, that makes plenty of sense. Buying oneweb to do it? The whole thing fucking smells of filthy backroom deals.

>>11983903
not even all of it, a lot or most of the stake is owned by an indian telecom company

>>11983903
I don't think it's that dumb—now is the time to start investing in space infrastructure. Basically you're counting on SpaceX/BO to decimate launch costs with their new vehicles and give you a leg up on the rush that ensues.

>>11983856

SLS is peak 1970's rocket design

>>11983903
The only possible idea that made sense to me was a cheapo military comms constellation, but even that doesn't make sense when they only one a part of it. Surely there MUST be some secret genius idea behind it? I can't believe the government doesn't have at least one adviser that can tell them OneWeb is DOA due to Starlink

>>11983964

>>11983781
I don't even understand this argument. Why can't the shuttle contractors just work on shit that isn't shuttle-derived trash? Do they all collectively refuse to do any new training or something?

>>11984032
Retard

>>11984037
If you design a new rocket from scratch you quickly find out the vast majority of Shuttle contractors are redundant. How many contractors does Starship or Vulcan have? Maybe a couple dozen. Not THOUSANDS.

>>11984037
Yeah same thing with ESA getting all pissy about SpaceX and saying they couldn't make ESA's operation too efficient by going for reusability, else what would their employees do for the rest of the year, to which the answer should be 'we've just freed your employees from 90% of their tasks, so fuck off and put that 90% towards something space related that's cool' not 'oh ok, please continue to piss billions down the drain in a job creation scheme that actually retards progress in space'

I'm honestly coming to the conclusion that the goal of lots of people is to hold humanity back.

>>11984037
>>11984069
>And then Charmeau (chief executive of Ariane Group) said something telling about why reusability doesn't make sense to a government-backed rocket company—jobs.

Meme answer: Shelby pls go.
Serious answer: long term it's better for the US economy to have cheap, reliable bulk lift of stuff to LEO to enable space industry that isn't just BUILD MORE SHUTTLE PARTS :DDDDDD. Boca Chica being on the Gulf means huge portions of the interior can even ship their extra thicc space payloads by water, as of course can any city on the coast. Imagine how much you could spread the cost of a Moon base or an LEO spinning hab across Congressional districts.

>>11983679
>First for plasma magnet sails
Didn't those get BTFO so hard in the first thread on /sci/ that the fanboys never made one again?

>>11984078

>>11984090
No, that was just the pigeons-playing-chess brigade flapping off to go shit on someone else's game board without reading the replies that validated the sail. An /sfg/ anon has also emailed Jeff Greason for clarification on some of the math, which checked out.

>>11984078
>these are the people organizing space programs
LITERALLY make 10 reusable rockets, and schedule 100 launches, build a fucking ESA space station, or 90 fancy deep space probes to perform more scientific missions

>>11984096
The article goes on to admit that Europe is so shit that they wouldn't have anything to do with more launches per year.

>>11984081
Here's another golden one.
https://www.spiegel.de/wissenschaft/technik/alain-charmeau-die-amerikaner-wollen-europa-aus-dem-weltraum-kicken-a-1207322.html

Assuming the translation is correct.
>SPIEGEL ONLINE: Meanwhile, SpaceX is cheaper.
>Charmeau: Excuse me, but this is not correct. You have to ask yourself why SpaceX is charging the US government 100 million dollar per launch, but launches for European customers are much cheaper. Why do they do that?
>SPIEGEL ONLINE: Because this way they can offer launches cheaper for commercial customers - like the german government.
>Charmeau: They do that to kick Europe out of space. The public and the politicians should know that. It is about the question, if Europe will still be active in space tomorrow. Our US friends do not really support this. I will immediately subscribe contracts with European governments for 100 million dollars per launch. This is the price, SpaceX is charging their own government. But if the German government insists to buy launches as cheap as possible, our US competitor benefits from that.

tl:dr/tl:cr - Charmeau believes that the US government is subsidizing SpaceX so that the company can offer launches cheaper than profitable so to drive out international competition.

>>11984103
What a retard. Everyone knows you charge the US government more money because
>the feds can afford it
>there are extra compliance costs involved with government contract work
And I'm sure the government enjoys sneaking Elon-chan more money to build Mars rockets in any case.

>>11984103
What competition, the French rocket? The electric kiwi one? Who's even real competition now?

>>11984032
>he has never seen treasure planet

>>11984078
>>11984103
Europe/Russians are god damn gold mine for retarded conspiracies. The fucking Ariane Group is french government(yes france is a communist country with lot of state owned industries) owned and is the SOLE rocket provider for ESA itself. ESA's funding is 8 Billion USD. That's 8x SpaceX makes per year.

>>11984094
what the fuck? can you elaborate?
i love the shit out of TP but i never know people would get so autistic about the "science" behind space vessels with breathable air on their open decks

>>11984115
>Europe/Russians are god damn gold mine for retarded conspiracies.
Anyone got the screencaps of the tweets where Roscosmos (or someone within it) implied that SpaceX might be faking their reuse or at least using it as a marketing gimmick only?

ESA is a useless space agency lmao

looks like nobody even cared to watch Astra's n-th attempt to launch last night.

(Scrub at the last minute: deluge system lost pressure. Kink in the garden hose?)

Trying again tonight. Only two more days left in their launch window.

>>11984139
>watch Astra
They livestreamed it?

>>11984103
to be fair SpaceX is kinda subsidized by the feds because the feds do offer them very generous contracts, also a Falcon9 launch could be priced at much less then 100 mil and still be pretty profitable for SpaceX

>>11984139
I was sleeping at the time. Are they streaming their next attempt?

>>11984151
>feds do offer them very generous contracts
Yeah but those contracts are 1/2 to 1/3 as generous as oldspace contracts. So if SpaceX gets "very generous" contracts, oldspace must be getting 24/7 blowjobs/titjobs service from feds.

>>11984151
I think there's a huge difference between a customer wanting to pay extra for their service, and a customer paying a company to dump the market.

>>11983688
Methane is odorless. Fart smells are primarily the result of sulfur compounds.

>So if SpaceX gets "very generous" contracts, oldspace must be getting 24/7 blowjobs/titjobs service from feds.
They were, thats what happens when most of Congress has their reelection campaigns funded by Boeing and Lockheed Martyn. SpaceX’s greatest achievement is getting a contract without paying for Congresse’s reelection campaighn.

Same as your gas torch.

>>11983801
Britannia will rule the Cosmos!

>>11984124
>can you elaborate?
Sure. The tl;dr is that the plasma magnet sail uses a relatively small amount of superconducting wire (the full sized version is four saddle coils forming a cylinder with 30m radius, 90kA average current) to couple itself to the solar wind, creating a magnetic sail over a thousand kilometers wide. That creates six kilonewtons of thrust[1], which is about 1% of the thrust of the Falcon 9's upper stage, but because your propellant is the solar wind you have an effective exhaust velocity of 400km/s and a mass fraction of "yes". The sail is also useful for braking into a planet's magnetic field on capture, and for decelerating close to the sun. Anons from /sfg/ figured out that this pairs extraordinarily well with a bimodal NTR engine, so then your mission profile looks like this.
>load payload, crew, and LH2 at refueling station near Earth-Moon L2 (using LH2 and crew oxygen sourced from lunar ice)
>use orbital hax to swing way down in perigee for very small initial delta-V, and use the NTR for maximum Oberth kick
>switch reactor to electricity generation mode once clear of magnetosphere and turn on the drive
>sail all the way to an outer planet
>if you're going to Neptune you can use the sail to capture on the magnetosphere with no additional fuel expenditure
>if you're going to Mars, the Belt, Jupiter, Saturn, or Uranus, use the NTR to brake on arrival, with partial aerobrake provided by the sail in non-rotating mode
>do mission work
>use reactor to electrolyze more oxygen and LH2 via local ice ISRU
>use NTR to accelerate back towards Earth
>use sail to decelerate and capture at Earth
This is all doable with current technology except the sail itself, and the sail has been tested in the lab so the next step is to fly one.

Here's where the Treasure Planet stuff kicks in.
>Because of the L2 launch optimization trick, you wind up with large spaceports on asteroids and moons, and chemical rocket ferry service to Earth and Mars from their spaceports. Pic related.
>The sail works on ships with hundreds of tons of payload, which allows cheap and fast mining of comets, asteroids, and small moons that don't require large landers, thus providing a space economy to use those ports.
>Thrust scales with sail radius and power needs are moderate, almost exactly like seafaring sail craft, so you could have small, fast pirate ships racing around preying on lumbering merchant men.

Chinese metallurgy and, as a result, engine technology is behind the west and Russia. Performance of any kind of Chinese liquid fuel engine can be subsequently expected to be lower than their foreign competitors. They’re obviously catching up, but it’ll take time.

>As of June 2016, the development was essentially complete, but funding for the manufacture of the flying prototype of the recoverable booster was absent due to the low expected launch rate.

Oh God do y’all remember that ariane concept of the starship equivalent that only ran on monopropellant?

Also the south korean government just said it “wouldn’t be worth the cost” to develop a reusable rocket from scratch. I assume other countries are thinking the same thing. How the fuck did Elon chad everyone out of the industry

Anyone who can read French? Anything wrong with this?

>>11984284
>Also the south korean government just said it “wouldn’t be worth the cost” to develop a reusable rocket from scratch.
So they will just buy old Falcon 9s once SpaceX retires them when Starship is up and running?
>>11984270
Why can’t ICBMs and SLBMs use liquid fuel?

>>11984284
>How the fuck did Elon chad everyone out of the industry
it really is incredible how SpaceX BTFO's every government-run space program on the planet. It's almost like capitalism works.

>>11984301
I mean most rockets are ICBM’s first, science rockets second. Reusability doesn’t matter when you have a huge budget and all it needs to do is nuke cities. Most countries focus on reliability > reusability.

>>11984304
>Why can’t ICBMs and SLBMs use liquid fuel?
Some do, but most good liquid propellants are either cryogenic or corrosive. Both aren't suitable to sitting in a silo for years ready to go on a moments notice.

>>11984304
I do hope that companies and governments just start buying Starships from SpaceX while the latter focus on making space travel cheap.

>>11984301
>Are scientists and engineers in Aerospace just retarded?
Most of them, yes. Elon is rustling all their jimmies because he treats rocket development like software development and it works.

>>11984289
>450s Isp
>monopropellant
Am I just out of touch with modern advancements in propulsion, or is that way too high to be realistic?

>>11984304
ICBM's need to go really fucking fast as quickly as possible, so they need really high thrust to weight ratios. It also helps that you don't have to fuel a solid rocket before launching it. You build it and it sits in a tube, ready to go at a moments notice.

>>11984317
Oh no it’s totally a meme. They have been shook by Falcon 9

>>11984304
>So they will just buy old Falcon 9s
ITAR and MTCR make that highly unlikely.

>>11984304
The first ones were liquid fueled. The problem is they have to be stored empty. So you have 30 minutes of fueling before you can launch nukes. Which gives spy satellites time to see you, or is too late for retaliation launches.

Solid rocket icbms and slbms. Are always ready to go. Most Chinese nuclear missiles are still liquid. As their nuclear stance(after mao), was bare minimum deterrence and rely on Russia.

>>11984318
>>11984325
Should just save the money and build a doomsday device.

>>11984325
>Most Chinese nuclear missiles are still liquid. As their nuclear stance(after mao), was bare minimum deterrence and rely on Russia.
Then why use SRBs for civilian rockets to subsidize ICMB and SLBM production?

>>11984305
>It's almost like capitalism works
BLYAT DELETE THIS COMRADE! Why develop new technology when we have a perfectly flyable Soyuz!?!!
>>11984316
To be fair Ariane has good stuff, for now. As the saying goes: the French don’t copy anyone but nobody copies the French. Alas... ESA’s fleet of rockets will soon be rendered useless by private American launch systems

>>11984284
>How the fuck did Elon chad everyone out of the industry
See >>11984190, before SpaceX the industry was pretty much entirely government ran. The trouble with this is that government ran industries like to keep things stagnant so they're easier to manage. A private company is usually motivated to try out new things partly because the losses are only personal rather than government impacting.

There's also the established knowledge base that you have to contend with. I've spoken with NASA employees who said that the pre-SpaceX assumption with reusable vehicles is that you have to design the vehicle from the ground-up to be reusable (ex: Shuttle), but that means significant upfront costs with the risk that the vehicle might not work as believed. SpaceX's method of building an expendable rocket and then making it reusable was "unthinkable" to NASA at the time, but it was effective because it allowed SpaceX to reduce development costs and make the design adaptive to any development challenges.

>>11984317
450s Isp is fucking hydrolox theoretical max. Claiming they get that out of monopropellant is lying.

Still can’t believe the hop went well. I was 100% sure it would RUD

>>11984325
>was bare minimum deterrence
Correct
> rely on Russia
The nukes were meant specifically to deter Russia more than anything. Khrushchev (allegedly) considered nuking China during the Sino-Soviet border war, and this caused Chinese planners to expand their arsenal to prevent such an action from being taken flippantly.

>>11984305
>develop new tech
My 1960's rocket system works perfectly fine

>>11984317
The monopropellant that could theoretically reach that Isp is metallic hydrogen and that hasn't even been made in a lab yet. My guess is that some intern messed up with the data sheet.

>>11984321
>>11984337
Good to know, I thought I must've forgotten everything I knew about rocket engines for a moment there.

>>11984333
Because nuclear stances change and old rockets need replacing. So modernize and go to Solid rocket.

>>11984338
I thought the same about Curiosity landing, I'm learning to be more cautiously optimistic these days.

>>11984344
>The ONLY monopropellant
Fixed.

>>11984332
Meme's aside, humans aren't anywhere near the tech level of doomsday device yet. Contrary to popular belief, the Earth as a whole would probably recover relatively quickly from a full scale nuclear exchange and it's unlikely humans would even kill themselves off that way. Probably the most physically destructive thing we could conceivably build would be some kind of kinetic driver/rail gun bullshit in orbit but that would get noticed pretty quickly.

Ironically the most "doomsday" thing humans have access to right now is probably viral agents. There are man-made viruses in government labs that could actually seriously kill off most life on Earth, but that isn't really physically destructive.

>>11984336
It’s amazing to see BIG organizations like NASA and even the fucking DoD trust SpaceX to launch personal satellites. As eccentric and weird as Musk is, he fucking came out swinging with Space Exploration Technologies and changed the game. I know /sfg/ talks about Starship a lot but there’s a reason for that. The thing is fucking amazing and is coming to life before our eyes. It’s more than just a meme paper rocket.

>>11984338
Elon you cheeky bastard.

>Liquid Fly-back Booster (LFBB) was a German Aerospace Center's (DLR's) project concept to develop a liquid rocket booster capable of reusing for Ariane 5 in order to significantly reduce the high cost of space transportation and increase environmental friendliness.
>LFBB would replace the existing solid rocket boosters, providing main thrust during the liftoff. Once separated, two winged boosters would perform an atmospheric entry, fly back autonomously to the French Guiana, and land horizontally on the airport like an aeroplane.
>German Aerospace Center studied Liquid Fly-back Boosters as a part of future launcher research programme from 1999 to 2004

So the ESA could have had reusable boosters at least a decade before SpaceX

No, that's INT-05. INT-18 takes the last two upper stages of the Saturn V and adds commercially available SRBs to them. It would've carried Shuttle-sized payloads to LEO while being cheaper.

Yeah I agree, to keep it on-topic i’ll also say that this line of thinking is dangerous to spaceflight. Why send humanity to the stars when we can complain about middle class white men and tax the shit out of them in order to obtain gibs for poor black babies. We speculate about Biden being dangerous for NASA, but progressive liberals are like ACTUALLY openly anti-NASA and anti-capitalist

With the advent of cheaper launch vehicles and more coming soon, being a startup providing launch services appears to not be profitable. Would a 4ASS space services startup be better? Such as; orbital tugs, reusable landers, and other servicing offerings for small sats.

Lmao I'm fairly certain this current trend of progressivism is temporary. It's just amplified because of the internet and things like the NBA openly advertising BLM for them. But space is forever anon (unless there's a big crunch). If Musk truly makes it to Mars you can god-damn-guarantee no marxist progressive will be allowed. There might be a few aboard the gay ass #dearmoon project, but the second someone tries to impose a white tax and refuses to work on Mars they will get thrown out the airlock because a small society can't grow with a parasite plotting to destroy it

Not quite. It was fairly useless compared to its size. Falcon 9 could carry roughly the same shit for 1/40th of the cost. The re-usability aspect was roughly similar in ratio.

The actual driver of that design was a 1970s USAF requirement to snatch satellites out of the sky and return to land on one pass. They ended up dropping that requirement.

It was pretty cool but everything it could do the Buran could probably do better. I think the Saturn V system was the craziest (in this case, including the LEM). I mean what the fuck. A huge skyscraper, a complicated CSM system, AND a lander that brought astronauts to the Moon. In the 60's. With a guidance computer threaded by hand. What an achievement from techno apes using chemical rockets- any alien visitors would be impressed with the capabilities despite the rudimentary technology

He can take all his money, though. Does SpaceX still own the patents despite this ITAR? Not a burger so I'm not too familiar with your laws.
Even if he can't, I'm sure he can figure out how to make even better rockets. There are likely some things in the works no one outside of SpaceX knows about.

Earlier versions of the Scud missile was propelled by ethanol and liquid oxygen. It was believed that Soviet soldiers assigned to the missile were drinking the ethanol fuel. This issue along with challenges of maintaining cryogenic temperatures on the battlefield has motivated the Scud designers to redesign the missile to be propelled by toxic hypergolics.

>>11984608
the US has incredibly autistic tax laws to prevent outright capital flight; it's one of the few countries that does, oddly enough.

>>11984604
The Rutherford Engine is mostly additively manufactured. This allowed for simpler engine design and manufacturing, both of which can be challenging for an engine so small. Interesting to note that the pipe on the side of the rocket engine which feeds the regenerative cooling system is also additively manufactured, despite that it could've been made from a simple bent pipe. I have no clue why Rocket Lab did it that way.

>>11984611
The HG-3 was going to be a future rocket engine to power NASA Apollo Applications Program. It was developed from the Rocketdyne J-2. The design switched the operating cycle to staged combustion and increased the chamber pressure to 3000 psia (from 763 psia). This greatly improved the performance of the engine, and since it was developed from the J-2 it can fit into the same mounting points that the J-2 allowing for smoother recycling of Apollo stages.

However, the engine was never tested as a complete unit and thus never flew, but the development from it was spun off into the RS-25

Just slap 4 proto RS-68s on the bottom of the external tank and throw on 4 extended and up-engined Atlas cores on the sides and you just built an American Energia.

Rex-engine will likely be reserved for a new next-gen engine that will come after Starship becomes normalized.

>>11984982
That's going to be the F1-sized engine for the 18m Starship 2.0.

>>11984991
Or the Orion upper stage engine for 36m Starship.

September soon, expect another Starship presentation.

Bigger fairing maybe a thing, and that will allow for bit more opportunities.

Hopefully in front of a finished SN8 with fins and nosecone, the comparison to mk1 will be incredible

did northrop give up yet

>>11985015
Most likely DOA. Cant compete with FH/F9/Atlas5/Vulcan/Starship/NewGlenn's offerings

>>11985014
I've never gotten a good answer for this but: what the fuck was the purpose of MK1? Was it just a mockup or were they originally going to fly it

>>11985026
Test article. It blew up in tank test.

>>11984963
>Buran riding a flyback Energia with 4 reusable Falcon 9 clones strapped onto it
Oh god please let this happen

>>11985026
They were originally going to fly it or Mk 2 until they saw how overweight it was.

>>11985026
I think it was just a mockup, that was put together back when they were still trying many different tests of welding techniques

>Cant compete with FH/F9/Atlas5/Vulcan/Starship/NewGlenn's offerings
I can't understand how an all-solid launcher can't compete on price with more complex liquid-fueled vehicles. If they replaced the RL-10 powered upper stage with something more reasonably-priced, would that make a difference?

>>11985052
The Omega was all solid? Fucking seriously?

>>11985054
Only first two stages of three.

>>11985054
why worry man

>>11985055
That's still pants on head retarded.

>>11985052
Solid 1st and 2nd stage with solid boosters and a "totally not centaur but still powered by 2 RL-10s" for a 3rd stage.

stack when?

I'm probably going to finish my BS in AE in Huntsville, so I'm hoping the gravy train keeps rolling for a few more years.

do we think sn8 will hop before elon's next starship presentation?

We are truly complete idiots for throwing out Saturn like that, we had such a headstart for fucks sake, fuck the shuttle

>>11985086
Naw. SNATE was a really good test and I have a feeling Elon will want to deconstruct the hell out of it. What went right? What went wrong? What tiny little improvements need to be made? That thing had sensors everywhere and they will need to compile all data gathered before doing another, more ambitious hop

This is why I love Eyes Turned Skyward. Saturn should've formed the basis for America's space infrastructure and STS could've been a fun side project.

>>11985119
Omg if it pops or explodes or something during a test, that would be hilarious. It would quite literally set them back 5 years. At that point Jim should just openly talk shit about it

>Elon posts this picture on twitter and says it's the new design for Starship
Wat do?

Aside from the fact that that would literally never happen, I'd just laugh

>>11985103
>>11984444

We didn't have to stick with the big one except if it was absolutely necessary

>>11985134
Nah that was the plan but it turns out it’s way more complicated. The shuttle was designed to hold a bunch of weight on the side. Turns out when you stack it vertically, suddenly having a second stage, a capsule, and a lander on top made the orange tank fail. So they had to use a whole new alloy of aluminum, a whole new system of internal struts, a whole new welding technique, and they changed to a whole new foam. SLS is literally gay as fuck

>>11985134
That's what it was supposed to be, a cheap refit of the Shuttle architecture sans Orbiter so we can get our boys back into space from our own soil within a year or so, instead they decided to go full retard and completely shit all over the intentions of the DIRECT team

>>11985134
Turns out orangetankbad is even worse than previously expected and needed major design revisions to handle the strain of directly attached RS-25s as well as a payload on top. And of course because it's fucking hydrolox every test iteration takes forever.

what were they thinking making orangetankbad in the first place
how hard would it have been to design a tank that isn't fucking retarded and doesnt kill everyone?

>>11985139
Still mad that they didn't take the obvious and easiest route

>>11985134
If it went fast then it wouldn't require as much funding, think anon. You sound like the goal here is creating a launch vehicle, not employing constituents and keeping contractors happy.

>>11985148
I don't even understand the muh jobs meme. Couldn't you employ more people to work on space shit if you could actually launch shit into space?
>>11985140
Also, why do you even need a super-heavy launcher? Why not just assemble Artemis in orbit with 2-3 launches?

>>11985147
fucking kek, why did I laugh out loud at this, it's brilliant

The good news? SLS, as shitty as it is, will always be better than anything other countries can launch. The bad news, it sucks because we know NASA is capable of so much better. Idk how y’all feel about the space shuttle but I think the flaws of SLS stem from the fact that the shuttle sucked ass.

>>11985141
>>11985144
Why is orangetankbad?
t. brainlet

full starlink shells when?

>>11985156
Pieces of the tank flying off and hitting the orbiter caused both shuttle crew losses. It's also big, ugly, expensive, fragile, and full of hydrolox for a first stage.

>>11985155
Why didn't we just buy the Buran-Energia blueprints from Russia? They probably would've loved to have the cash at the time.

>>11985153
No, the problem was that shuttle was supposed to be east maintanence but over the course of its design life it got more and more complicated and ended up giving lots of people jobs. Once it was cancelled SLS eventually made it to the table under “cost-plus contracting” where you weren’t penalized for going over budget or missing deadlines. There’s literally no repercussions for going slow and asking for billions of dollars. In hindsight NASA should have just told everyone to fuck off after shuttle (desu I don’t know WHY they wanted to keep everyone employed. Most likely because it meant they would get more funding from Congress)

>>11985153
>Couldn't you employ more people to work on space shit if you could actually launch shit into space?
not in your constituency

>>11985161
Did NASA even want to build the SLS? It seems almost like it was just forced on them by retard senators.

>>11985158
>Pieces of the tank flying off and hitting the orbiter caused both shuttle crew losses
Challenger was catastrophic o-ring failure on one of the SRBs, not tank debris.

>>11985161
>I don’t know WHY they wanted to keep everyone employed
Seems like pretty straight-forward corruption to me, buy a senator and you'll have made a friend for life without term limits.

>>11985161
>I don’t know WHY they wanted to keep everyone employed
There were contractors in every Congressional district. It was impossible to kill.
