>>12252356
They fuckin lost the competition, same as Northrup. If Chair Force makes and exception for Blue, imagine the lawsuits. Also, since when is money an issue for Jeff? He's dumping 1B of Amazon stock per year into that pit. And why is Blue clamoring for the national security launch scraps left by SpaceX and ULA? They should focus enturely on Kuiper IMO since there aint much commercial market left for them to speak of. Guess you get what you get when you hire oldspace and reject SpaceX enployees

>>12252396
>since when is money an issue for Jeff?
He'll have to pay taxes to bring it back into the US and consequently dump it into Blue Origin. A lot of taxes.
Jeff does not like paying taxes.

SLS absolutely must detonate during the greenrun if the program is to be cancelled. There is no path to shutting it down otherwise

Hey Faggots,

My name is Jonny, and I hate every single one of you. All of you are fat, retarded, no-lifes who spend every second of their day looking at stupid ass pictures. You are everything bad in the world. Honestly, have any of you ever gotten any medical degrees? I mean, I guess it's fun making fun of people because of your own insecurities, but you all take to a whole new level. This is even worse than jerking off to pictures on facebook.

Don't be a stranger. Just hit me with your best shot. I'm pretty much perfect. I was a medic in the Navy SEALs, and top of my astronaut class. What accomplishments do you have, other than "jack off to naked drawn Japanese people"? I also get confirmed kills, and have a very sweet wife (She bore me three children; Shit was SO cash). You are all faggots who should just kill yourselves. Thanks for listening.

They should focus on making an orbital rocket that will put things in space first.
Or at least a BE-4 that will work on another rocket.

>>12252439
elon said they fixed the resonance like a year ago, and clearly they didnt. it's not the thrust puck that's the problem, it's the raptor itself

>>12252452

Why, is it because they're smart and you're just not?

>>12252517
No lad, just a hard working Memesman out here trying to make an honest day's meme.

>>12252509
What's the point of building a rocket if they have nothing to launch on it? You're right about BE-4 though, BO droppin the ball hard on all fronts

>>12252527
I agree you should have a market to launch stuff before building the rocket. According to Jeff Who and BO reps, there are plenty of contracts already signed for New Glenn to launch payloads.
Either way, BO keeps whoring for contracts and launches but has nothing to show their capability. Some people are going with them because its not SpaceX, or they offered stupid low prices.
The Air Force was pushing money towards them and still hasn't seen even an attempt to launch anything - prototype or not. After seeing the garbage SLS has become, I'm not surprised they told BO to get out.

This is from last year, how did you know today's issue was the same, elon hasn't even confirmed it?

>>12252639
and also Google and DoD behind Starlink.

>>12252606
"Looks like" is not a term you use when you say something is fixed. That's a term you use when you hope something fixed itself and you're praying really hard that it stays that way.

>>12252668
that's a lot of stretch and projection. more likely the problem seemed to be fixed but needed more testing. especially if it comes from single engine stand tests, it's impossible to say 100% what will happen with three engines on an actual vehicle from that.

>>12252601
God damn, really looks like actual conceptual space art. 10/10

>>12252671
Did they actually ever fire more than one engine at once?

>>12252656
>>12252671
>>12252664
this is a well known issue with Raptor shutdown. It did go away for awhile, but has since reappeared. Elon's mentioned it multiple times, you'll have to check NSF forums for more detailed info. This instability in the past resulted in an engine swap

Lmao remember when they installed the RS-25's at Michoud and got all excited? Yeah well SLS has yet to do anything important after that, and it's been a year. And that's only ONE booster. This thing will need multiple boosters if they want to fly more than one mission.

>>12252689
They get excited over at Michoud when they put in a fucking bolt in the SRBs.
Must be the dreariest fucking place to work in aerospace.

>>12252676
it's possible they didn't, just going off of what seems to be general consensus. other anon said they've had the same thing on previous prehops so it seems more likely to me that the problem translates poorly from stand test to static fire, but if multiple engines are resonating at once it makes sense it would be more noticeable

>>12252689
Seriously. What’s the time delay going to be between Artemis I and Artemis II? They will need to build an entire new booster: which doesn’t look like it’s happening? Was the Saturn V also made at this same rate, or faster? The entire SLS program is a mind boggle.

>>12252676
they don't have the capability to fire more than one on anything other than prototype starship tankage.

>>12252665
Yeah this is basically Microsoft buying into Starlink. They might be Starlink's second biggest customer after the military, or maybe even first depending on traffic? Someone said that Azure makes up 20% of the cloud market. That's alot of internet traffic.

>>12252701

>>12252701
The Saturn V was announced in 1962, and first launched in 1967. NASA is definitely dragging its feet getting SLS ready.

>>12252689
>and got all excited?
They've been doing this for every tiny incremental step of progress the SLS has made since it started. It's one of the most infuriating aspects of its development

>>12252689
SLS is real. You've seen it down at Michoud. We're building the core stage. We have all the engines done, ready to be put on the test stand at Stennis.

Mommy Shotwell talks with Tom Keane of Microsoft, video unlisted-
https://youtu.be/aY1_UMQvTcw

>>12252565
You have a highly enriched fissile fuel embedded in solid propellant that you burn from the bottom up like a candlestick, and as the SRB exhaust passes through the nozzle a nuclear fission reaction is initiated and sustained by the moderating effects of a surrounding tank of deuterium oxide (heavy water). This causes the temperature of the exhaust to flash from ~2300 celsius to >40,000 celsius instantly, greatly increasing thrust and Isp, but you need to use water for active cooling of the nozzle OR an opaque gas to insulate the nozzle from the nuclear exhaust.

What would be the minimum size and weight of a metallic fuel fission reactor used as a NTR engine?

>>12252668

Does Musk like, legit have autism? I've noticed he has a scar on his throat and my brother told me it is most likely due to a thyroid surgery. He claims the thyroid is connected to autism but I have no idea how that makes sense.

>>12252808
What the fuck is "autism" today? That term has been watered out to the extreme. I've actually spent some time working as a tard wrangler at a small company for downies and actual autists about 25 years back, this was long before autism was considered a "spectrum". There was rainman tier autists there. A dude who you could give a date to and he would list famous people who were born that day.

He's not neurotypical. Then again, what the fuck is typical.

EBR-1 was a nuclear reactor that was first in America to generate electricity for the grid AND it was a breeder reactor, yet its core was the size of a big lunchbox. Literally 7 inches in diameter, about a foot and a half long, and produced almost two megawatts of heat. That's probably the lower limit for the size of a nuclear thermal rocket engine core.
On that note, it would probably make sense to have NTRs be very small in every case apart from surface-to-orbit shuttle craft operating from objects up to Ganymede in size. NTRs have low thrust to mass ratio but better efficiency than chemical rockets, which means if you want a normal total stage mass but improved delta V you need to keep your engine no more massive than a typical chemical engine. Otherwise despite being twice as efficient your 20 ton engine will add so much dry mass that your delta V will just go down.
A tiny NTR that only produced a kilonewton of thrust would still be extremely useful for any spacecraft operating in a low TWR requirement environment, like the asteroid belt or among the irregular moons of Gas giants. Vehicles propelled by them would be able to refill their main propellant tanks with water and get back their entire delta V budget in weeks if starting from scratch on virgin land, and in hours if landing at an established DEPOT

Fast, low latency data streaming for cloud centers via Starlink. MS gets to leverage even lower latency than fiber can provide, and over long distances. Azure gets an competitive leg up over Amazon Web Services. Basically it's a match made in heaven, and Jeff is on suicide watch

>>12252786
I expected Google to jump at Starlink's capability since they own like 20% of SpaceX. But microsoft got to it first. Not only does Google own portion of SpaceX, SpaceX's Starlink is an unofficial successor to Google balloon/fiber internet. Both Musk/Larry Page/Google execs talked with each other about it.

>>12252818
Really nothing groundbreaking, data centers could already transfer data to anywhere, but they will get better speeds with starlink if the distance is far enough it needs to span lots of networks.
For starlink it's a huge win for optics. A FANG company legitimizing your business and product is huge. This could also be another revenue stream for starlink, renting out priority starlink bandwidth to companies could be a real money maker.

It's because he works 130 hours a week and sleeps in 3 hour alotted time slots, stimulating himself with caffeine in between and constantly working with teams at his various companies to solve a massive variety of problems.
Elon is what you may call "strung out". He's not unhappy about that though, he's like if one of those old 80 year old men who spent their entire life perfecting their ability to make the exact same clay teapot a billion times had gone into the tech industry instead. He's a total workaholic to the point that if he stopped now his system would crash completely.

It's not just connecting to Azure, but connecting remote areas to Azure. If you watch the videos they are talking about mobile Azure platforms (literally shipping containers) that they will send to remote areas, disaster areas, and military operations. Azure's customers will connect these Azure shipping containers to the main Azure network using SES and Starlink. It's very useful for enterprise and remote customers.

Damn that is really strung out. I hope he still spends enough time with his sons. How will we get the great Marian Musk dynasty if the sons are raised without a father.

Could we miniaturize a MOXIE system for recycling CO2 onboard a spacecraft if a Mini pressure swing CO2 concentrated the exhaled CO2 for feedstock? That way, we don’t have limited Lithium scrubbers and you could recycle more water rather than just using it for oxygen
Maybe we could miniaturize down to a reasonable size for a space suit

Wait, the stations in Elite are literally just copied from 60s art?

https://ntrs.nasa.gov/citations/19750016730

1975 Boeing study of future space program possibilities. A lot of the 1969 integrated program plan stuff shows back up here as they try to figure out ways to make it happen with a shuttle infrastructure.

The most interesting part is their preferred choice of heavy-lift launcher:

>a configuration using either two or four SRB's clustered around a modified shuttle external tank (ET) made into a stage, fitted with three space shuttle main engines (SSMEs) in a recoverable propulsion package.

So Boeing came up with a better shuttle-derived rocket than SLS in 1975, without really putting much effort into it even.

>>12253007
To be fair, 2001 copied from 50s art of Von Braun's concepts

>>12252980
He's expressed interest so it's not an ideological opposition, but yeah I don't think it would be worth it for SpaceX with political issues taking precedence over engineering ones

>>12253007
>2001: A Space Odyssey released in 1968
>Elite released in 1984
The developers of Elite most likely drew some inspiration from 2001.

>>12253024
Assuming Musk go infinite gooberment money to "build the exact rotating station from 2001" could he do it? Either with a 9m or 18+m starship? Could it be build in parts?

>>12252979
ECLSS are a whole thing anon.
Ideally you could couple CO2 scrubbing, O2 generation, water filtration, and even food production with algae.
That's hard though, SpaceX will probably focus on this when they need it and see that public research is slow as fuck.

>>12253028
Anything is possible with cheap launches.

>>12253028
With Starship you could start building all sorts of giant pieces of orbital infrastructure. At that point the hardest part would be getting the parts built to begin with, not getting them into orbit or assembling them.

>The game plays the Blue Danube when you use the docking computer from the very first versions of the original game
>"The developers of Elite most likely drew some inspiration from 2001."

The station was clearly supposed to be constructed from pretty small pieces since you can see the unfinished sections with the scaffolding

>>12252979
MOXIE is actually a joke, I am dumbfounded by how that experiment made the cut on the new rover. What a waste of mass.

>>12253193
If you have excess square km of room, grassdomes with cattle (or bison or ostriches, they use less water) are unironically a better way to get meat than steak proonters - the whole animal being available for use matters. Hooves for glue, skin for leather, etc.

What are the numbers on this? I always heard farm animals are innefficient in terms of the calories/water you put in vs what you get out.

Insects are a reliable and common part of the human diet historically, yeah. Grubs in particular are something I look at and think “That thing should be eaten by me”. They look delicious.

Why don't we use some room-temperature stable fuels and oxydizers like hydrazine derivates and ClF3 instead of hard to handle and constantly boiling off LH2 and LOX?
That stuff would also be more dense, meaning you can save weight on smaller fuel tanks while having pretty good specific impulse.

>>12253449
Yes, with sufficient hunger, you’ll eat nearly everything

https://pubmed.ncbi.nlm.nih.gov/11305594/

Phytoestrogens bond to estrogen receptors. When estrogen receptors bond with an estrogen particle, or something that appears to be one, they travel to the nucleus and begin regulating gene expression in a “feminine” manner. This difference in gene expression is why men and women have different body fat distributions and whatnot.

>>12253028
Yes. We are separated from giant space construction projects by three technologies, and only one of them is actually a hard problem.
These are cheap launch to orbit, real-time remote operation of robotic factory machinery, and a space-worthy electron beam welder.
If we can launch a 100+ ton roll of steel into orbit for $5 million, the materials cost of a 10,000 ton space station is half a billion. The ISS masses ~500 tons, and cost ~150 billion, so the station you could build using rolls of steel bend, cut, and welded in space could approach as little as 1/300th the ISS while having 20x the internal volume. If you devote 80% of that station's volume to propellant storage at an 80% mass ratio you have a single stage vehicle that has a wet mass of 42000 tons, a dry mass of 10,000 tons, and a delta V budget of ~5 km/s if using only methalox thrusters. If you're using methane NTR instead, you have 8.4 km/s of delta V and can go all the way to Jupiter orbit. In fact you can go all the way to Jupiter orbit while carrying an additional 2000 tons of payload, which could be an entire fully loaded Starship with its own payload on top of its propellant mass.
Basically we'll be able to build one-shot spacecraft that can set up an entire surface base and propellant production facility in the Jupiter system in just a couple decades, pessimistically.

that's just the thing. You have to jump through a ton of hoops to GUARANTEE that you never spill any. It's a pain in the ass and sensitive to changes in political policy.

>>12253634
That fuel has lower performance and you need to build a more complex engine to run it.
Hydrazine + ClF3 doesn't even need an ignitor, just a preburner, a turbopump, an injector and an ablative nozzle made from phenol impregnated asbestos.

>>12253474
Cryogens are not a big deal once you have the hardware understood, which we do.

The benefits of density VS Isp land on a sweet spot, and that sweet spot is closest to the performance of sub-cooled propalox.
If you consider more factors, like ease of ISRU and optimizing for engine reuse metrics, methalox becomes superior to propalox, though not by a massive amount.

>>12253651
Don't forget.
>BUT your project is going to canceled by the new administration because your mission development was lean and didn't kiss the ass of Congress across all the states

>>12253644
Hydrazine and ClF3 have a pretty good specific impulse and you don't need the fuckhuge tanks like LH2 does.

>>12253602
Yeah, I just mean that you can't go out and buy a welding robot that works in space at the moment, so that's a barrier between current day capabilities and the ability to build large non-retard structures in space. Not a huge barrier, but a barrier nonetheless.

>>12253670
Yeah, CIF3 has good specific impulse. Except for the fact that it eat fucking everything it comes into contact with including tanks, combustion chambers, engines and pad personnel.

>>12253661
Ablative nozzles are harder and shittier to manufacture and operate than regeneratively cooled nozzles, unless you're working with solid propellants.

>>12253673
Honestly, with launch costs being what they are, it seems like the actual assembly wouldn't be hard.

Just do it like ikea furniture where there's a simple "put tab A into slot b" assembly process. Maybe have little electromagnets to stick the welders to the parts, and stick the parts to each other during the welding process.

>>12253719
Did you miss the whole Enriched Uranium bit? There's a reaction going on there, those hydrogen atoms don't go through there unmolested. They get turned into shit like deuterium - 2H (most common) and tritium - 3H (very unlikely).

Deuterium is what makes Heavy Water radioactive after all.

>>12253728
Yes, it does. But not tritium, that requires lithium in the mix to occur.

>>12253755

A stray neutron produced by the decay of Uranium-237 gets captured by Hydrogen-1, turning it into Hydrogen-2, or Deuterium.

It’s okay SLS was supposed to have a wet rehearsal in 10 days but it just slipped. Again. It’s all so tiresome.

>>12253822
>lost a good number of them
when?

>>12253844
>kill
The proper word is "high risk testing"

>>12253863

>SpaceX’s propulsion development team have struggled to get any single Raptor engine to survive more than 50-100 seconds of cumulative test fires. According to information from sources familiar with the program, Musk has enforced an exceptionally hardware-rich development program for the first full-scale Raptor engines to such an extent that several have been destroyed so completely that they could barely be used to inform design optimization work

>This is why SpaceX has been chewing through an average of one Raptor engine per month since February 2019 – by testing engines to destruction and aggressively comparing engineering expectations with observed behavior and post-test hardware conditions, rapid progress can (theoretically) be made.

>Instead of spending another year or more analyzing models and testing subscale engines and components, SpaceX dove into integrated testing of a sort of minimum-viable-product Raptor design, accepting that the path to a flightworthy, finalized design would likely be paved with one or several dozen destroyed engines

Just chop down the biggest fucking redwood on the western seaboard, sharpen it into a stake and put it through the core stage already.

>>12252307
I like that hop

>if you only knew how bad things were
Looks like they will even be a good bit worse than the air force

>>12252513
B...B..But it's the most advanced rocket eva!!!!!

boomer astronaut has to leave project mercury before going to space in order to help out on his family farm.
years later he decides to replicate mercury-atlas in his barn and follow his dreams, making nasa and the feds cope and seethe

>>12253883
Same way NASA built and tested the F-1
Good vibes man

>>12253874
Thanks!
Hopefully those museum engines will never be used & dumped into the ocean.

>Oh no, we absolutely HAVE to launch NOW

The ones currently strapped to the the beast that shall not be named are historic engines and they will go in the drink if it doesn't RUD.

>>12253844
Starting sentences with "I mean" is pure Reddit

>>12253913
WHICH IS WHY IT MUST RUD

SLSME is the most advanced engine ever made, Starship may be neat, but its a pipe dream, SLS will send the first female American astronauts to the moon

>>12253922
Personally I'm more in the "put a stake through its thrice cursed foam core" camp.

Have fun. I await the liveleak of you getting yourself killed

>>12253918
Shut the fuck up nigger

>>12253927
If SLS flies EM-2 in 2023 I’m confident that it would beat Starship to the moon, yeah. No joke even.

>>12253883
Isn't that how SpaceX does kind of everything?
>starship tanks/hoppers
Allways blowing up, but improving quickly.
>propulsive landing
Many blew up before they nailed it, now it's a routine operation.
>Falcon heavy
That thing was very likely to blow up.
>evolution of F9 from first flight to full thrust version
It also blew up quite a few times.
>Falcon 1
That thing failed 2 out of 3 flights and laid the foundation for Falcon 9 and Heavy.

And besides that, even if the first batch of Starship/Superheavy engines need maintainance or replacement parts every launch, that's enough to do the job for NASA as the lunar lander uses different engines anyway and all raptor flights would be unmanned.
That brings in a shitload of cash to further develop raptor.

>>12253952
I think SLS will fly before New Glenn

>>12252340
>>12252351
>>12252513
Not exactly ~600hz, but I guess the profile looks somewhat similar to the raptor honk on starhopper with the 2nd harmonic. 2nd harmonic is at about 500hz. The second honk is roughly a semitone higher than the first one. I wonder what two structures could have caused those.

>>12253964
Tbh the order of likely hood for first orbital flight will be
>Vulcan next year
>SLS
>New Glenn
>Starship (maybe lmao)
You can't launch a rocket into orbit with engines that don't work

>>12253952
>If SLS flies EM-2 in 2023
That's a big if, given Boeings track record and they will most likely require several unmanned tests before human rating SLS.
>I’m confident that it would beat Starship to the moon, yeah. No joke even.
I don't think Starship will do it before 2023, but I don't think Boeing is going to pull that off either.

>>12253982
Yeah it’s weird how New Glenn is super secretive though. We have no idea how far they are at the moment. We do know that BE-4 had some issues and is the main reason Vulcan was delayed.

>>12253982
Vulcan and New Glenn both require engines that currently dont work. SLS will launch first of all these, New Glenn last

Hey we were supposed to have the starship update this week. What gives?

>>12253206
>says he's a catgirl
>posts a picture of a dog

>>12254000
Elon time.

>>12253989
It's "super secretive" because it only exists on paper and BE-4 is nowhere near as far along as raptor.

I know orange tank bad, but why is orange tank bad?

>>12254011
Orange tank is not bad, but the politics around SLS’ creation are awful. If SLS started flying in 2017 like intended, it wouldn’t have been so bad

>>12254004
I want to fuck everything

>>12253145
It’s obvious to anyone paying attention that Texas is where the future of rocketry is. Florida may have more existing infrastructure but much of it is mothballed or badly in need of refurbishment, Texas is where Starships will launch from and until a competitor shows better results, Starships are the future of large scale heavy lift American rocketry.

>>12253313
just spin your chickens bro

>>12254011
Because orange tank in development in one way or another for 20+ years and 20-60+ billion dollar spent already on the program with 0 results.

>>12254013
>If SLS started flying in 2017
The concept is so old that there's concept art of it with a white tank. Because Shuttle was still using a white tank.

>>12253602
yeah but they fucked it up and almost died

>>12253644
subcooled propane, anon

>>12254028
Dude if we had that thing flying in the 80s that would’ve been really cool. Also Constellation program was neat but by the end of it it was not even shuttle derived anymore

>>12253726
>it's easier to teach Mexican welders how to wear a space suit than it is to teach Spot to weld
>delightfully belterintuitive

>>12254044
Why add more carbon to the mix for no extra impulse when methane does just a good a job?

>>12253982
I would hope BE4 works perfectly at this point considering how conservative it is and how slow its development has been but until they have been tested to a comparable degree, this is conjecture. It's only because Raptor gets to leave the test stand and get real world data that SpaceX knows its actual limitations.

>>12254049
Mexicans are based.

Calling the wolf 2hus "anime catgirls" is a long and proud tradition.

Is this from NSF or your own doing? Because if it's you I applaud the 'tism

>>12254055
Until you start with the beheadings and shit. That fucking aztec blood, man.

>>12254052
Even Tory Bruno said that BE-4 was having issues....last month. Shits bad

>>12254011
hydrogen first stage, big orange hydrogen tank

>>12254058
I don't think NSF would call NSF spergs or call the Raptor instability "braaaaps"

>>12254065
Why don't they just switch to Raptors? Don't say "it's not that easy in rocketry" because it totally is

>>12254022
once the government abandons the Cape completely, the rockets will return without the red tape
it's such prime land
>>12254051
propane, when chilled, is much denser than methane, and density is king
>>12254057
sorry, I wouldn't know, I don't go to shitholes

>>12254074
Political issues. ULA and SpaceX are competitors. Raptor shits on BE-4 though

>>12254076
Density is not king if you're looking for a quick turnaround and would rather not be scrubbing tar out of your engines with a fucking toilet brush.

>>12254074
by oldspace standards Raptor is still having issues

>>12254011
It killed the Challenger and its inability to take vertical loads has delayed SLS for like a decade.

>>12254074
Raptor was never on offer, if I were SpaceX I wouldn't put it out there either, unlike Blue Origin they aren't really desperate for oldspace partnerships and the value proposition isn't there

>>12253819
What the fuck do Microsoft know about building satellites - of any description? Their software is fucking dogshit on a good day
