I love Jim so much, I could listen to him talk all day. He’s such a good salesman for space flight without coming across like a conman or a dumbass reading from a script.

Imagine how happy you'd be if you were a little kid watching the first Shuttle missions in the early 80s and wanted to work for NASA, and then you grew up and it actually happened.

Endeavour undocks from ISS on Saturday and splashes down with Bobendoug on Sunday. That will be the first successful American manned capsule return since the 1970s, and the first successful American astronaut return since 2011. I think at that point he can hug Elon on camera.

>>11943141

Jim is liked among both Democrats and Republicans, and among the public which is unprecedented. I know the trump shills have been spreading the meme that Biden will #cancel NASA and give all the money to reparashuns but there's no evidence of that outside of doomerposting.

>>11943155
>Susan Rice as a running mate
Bullshit. It'll be Klobuchar. Trump only narrowly won Wiscosin and Michigan. The Klob-ster could help him lock them down.

I'm actually a fairly optimistic guy.

>>11943175
It's probably based on what Obama did. Which was a reasonable concern, but that was a time when Constellation was messing up big time and the economy was poor so Obama had to cut down on something. Nowadays, space seems more popular than back then. As much as it is to poke fun at the "whitey on the moon" reaction to DM-2, it's a small reaction compared to the overwhelmingly positive reaction to America making a comeback. The future for space flight is looking bright.

>>11943141
That was me.
As a teen, I watched the first Shuttle missions, especially during the early 80's. Back then before 1982, in black and white.

>>11943189
Plus, Obama seems almost vindicated at least in his decision to kill Ares and to kick off Commercial Supply and Commercial Crew though his refocusing on the asteroid landing was less so. Space is just so incompatible with the political narrative cycle length. Kennedy setup Apollo, Nixon brought it home. Obama setup commercial crew, Trump brought it home. Trump setup Artemis, Biden(or Trump) will bring it home. Americans love success and national dickwaving, so unless we have a global crash on the scale of 08' we should be able to get gateway built.

The funny thing is that /pol/ memed the Ok sign into being a symbol of white supremacy and you were so desperate for a boogeyman that you took the bait hook, line, and sinker.

>>11943244
Obama was justified in killing Constellation and starting commercial orbital services even if the political machinations behind it all are muddy as hell. Although, what happened to the asteroid redirect mission? Did something come from it or was it all paper designs?

>>11943255
Nothing really, that's why Gateway was so crucial to the mission architecture. It gave NASA a reason to go back to the moon, even if Obama forced them to put it in this strange "kinda around the moon" orbit.

>>11943255
Besides proving space exploration is still worth it to the public. It will result in gateway's construction which the keypart, once gateway is built congress is going to keep through money at moon missions so as not to be the morons who let a perfectly good space station go to waste. That will result in a constant stream of funding and missions beyond LEO which is good for building a toehold in deep space.

>>11943255
Dress rehearsal for Mars.

>>11943281
Not really, since a single manned landing where you also happen to plant a flag can accomplish more in a couple hours than all the rovers combined have done in all their years of service. On top of that it can also do things simply impossible to expendable single-use robots, like return sample payloads of significant mass for more intensive study on Earth.

>>11943281
>Mars robotic science missions will achieve so much
Anyways, there's so much more to manned lunar or Martian missions than flag planting. It's just Congress is trying to kill it for only flag planting.

>>11943282
Please stop feeding the troll, and post more space flight memes.

>>11943283
Honestly, I can't tell you what happened to the asteroid redirect mission. If I had to guess it fell prey to the Boing! delays with SLS which would have been the primary launcher of the whole assembly, but honestly I have no fucking idea.

Also thank god some else gets that Gateway is purely a political chain to keep the funding flowing towards space.

>>11943294
All I know about the asteroid mission was that NASA did some studies as a front while they tried to squeeze in what they really wanted to do into the mission.

>Also thank god some else gets that Gateway is purely a political chain to keep the funding flowing towards space.
Gateway is blatantly just ISS 2.0. Where NASA got international partners into the ISS to justify NASA having a continued manned presence in LEO (in the hope that space flight would pick up again), Gateway would be that but around the moon. The design elements and nebulous mission goals make that clear.

>>11943281
permanent boots on both the moon and mars will achieve more than both

>>11943306
The orbit alone is a red flag in that regard, needing more delta-V to reach from LEO than LLO does. Resupply missions alone require a steady stream of Mars-capable launches like Falcon Heavy and Delta IV Heavy (or Vulcan, Starship, and New Glenn when those come online), thus finally raising the base level of "space station resupply rocket" above LEO toys.

>>11943325
>delta-V to reach from LEO than LLO does
I thought it was the other way around? I recall tons of criticism about how reaching the lunar surface from NRHO requires more DeltaV than from LLO.

>>11943335
It's both, actually, since it's technically a halo orbit around L2. NASA trolling Congress into funding this is a master stroke of financial judo.

>>11943240
Guy literally said subscribe to pewdiepie to the camera before the shooting, yes it's a fucking joke

>>11943421
Artemis is a meager budget increase to give SLS some missions. It's just as vague as SLS and Constellation were.

>>11943424
Hilariously enough, Dragon/Falcon is NASA's most flight proven stack right now, so an extension of that is the safe, iterative design, while Starship is the next-gen research project.

>>11943440
Forgot to add that Artemis is flying a hodgepodge of Orion and a redesign upper stage to get to the moon since they've been dragging Orion since Constellation.

Assuming SpaceX sends humans to Mars at least sometime in the 2020s, and then begins their colonization plans, will NASA still do its own set of Mars missions, independent of SpaceX?

>>11943452
>will NASA still do its own set of Mars missions, independent of SpaceX?
With what rocket? SLS is still a paper booster.

>>11943421
If only Congress were interested in accomplishing the Artemis objectives as quickly and cheaply as possible.

>>11943454
Not this fag again. Starship is more of a “paper rocket” than SLS at this point, you realize that right?

>>11943454
>With what rocket? SLS is still a paper booster.
SLS will happen, just the later iterations will never be a thing. I think once spacex lands humans on mars, there will be massive push by congress for NASA to send people to mars.

>>11943454
We really need a term for the intermediary stage between paper rocket and finished rocket. When most or all of the hardware exists and is even partially assembled for a given rocket, the term "paper rocket" is just needlessly derogatory.
There are plenty of other criticisms to levy at the SLS, why choose the inaccurate one?

>>11943477
Because this guy is fishing for (you)s

>>11943452
No, NASA would book flights on Starship. I don't think any amount of lobbying could bribe NASA to develop completely independent Mars infrastructure, especially when private contracts are the path Artemis is currently taking.
Regardless, SpaceX seems to be developing Starship with the intent of winning the government's support pre-boots on Mars.

>>11943466
>he still believes that SLS is real

>>11943483
>No, NASA would book flights on Starship
Even if starship has literally hundreds or thousands of flights by the late 2020s, I doubt NASA would human rate it.

>>11943483
>I don't think any amount of lobbying could bribe NASA to develop completely independent Mars infrastructure
Given that they want a multiple launch providers, they'll support Boeing or BlueOrigin to develop one.

>>11943502
>Presenting the NEW Boeing CST-1000 Starcruiser with improved MCAS

>>11943502
Well I can tell you right now they aren’t doing business with Boeing after SLS. Jim has been super passive aggressive about meme-plus contracting recently and it’s pretty apparent he’s disappointed and angry with boeing’s lack of progress despite their absurdly large salary. He’ll most likely be throwing money at SpaceX and Blue Origin for Mars (assuming he’s still around)

Wrong on two ends. Shelby still controls senate funding. Boeing is there big time in his state. Kendra Horn is a Boeing support, she has a lot to say on House funding. Literally threw a hissy fit when Boeing didn't win Lunar lander.

>>11943518
Not that anon, but NASA does seem to have very strict requirements for human rating rockets. They forced SpaceX to freeze the design of the Falcon 9 for rating, SpaceX gave up on trying to human rate the Falcon Heavy, and NASA right now won't consider flying astronauts on reused boosters. NASA would need lots of convincing to human rate a cutting edge vehicle like Starship.

>>11943227

>>11943546

>>11943547
Musk didn't even create SpaceX. He's just an evil capitalist who bought it from other engineers. Reusable rockets will never work.

>>11943495
NASA intends on human-rating a Starship-derived lunar lander, which cuts out most risk of the full version, but shows to me that they're generally okay with Starship. The only questionable safety aspect about the Starship architecture is its lack of launch abort, but NASA astronauts could just launch on another rocket and transfer in LEO.

>>11943540
Early Starship prototypes don't really count as a Starship static fire. The only difference between Raptor and BE-7 static fires is that the Raptor was probably more accurately mounted.

>>11943536
Lmao starship is flying astronauts to the Moon for artemis, have you forgotten? Although I see where you’re coming from. I don’t think NASA would be comfortable actually launching them on a SS, much less wanting them to land on Mars or the Earth with that suicide burn

>>11943553
I think that’s why NASA is comfortable with Starship, because the astronauts will be launching on Orion and getting in the starship lander once they’re at gateway. Also landing a starship on the Moon is a lot more gentle than landing on Earth or Mars. It’ll be interesting to see if NASA will require a human rating or something for the final starship

>>11943553
>The only questionable safety aspect about the Starship architecture is its lack of launch abort

>>11943546
I guess I missed that development. I was thinking back to all those years when NASA was paranoid about the reliability of reflown boosters. Thanks for updating me.

>>11943558
In theory, going between the lunar surface and LLO is much easier than between the Earth's surface and LEO so NASA might have rationalized way their fear using that.

>>11943572
Especially considering how the shuttle was a death trap they should evaluate some sort of launch abort.

>>11943583
>full engine out on landing

I think such people who honestly think that are ultimately a minority. Most people don't really care that much for space flight and their support can go either way. As long as space flight can demonstrate actual work and physical examples of its achievements rather than play around in paperwork and studies, then I think it'll be fine. Most people don't care about marine trade and transport, and yet you don't hear anything about defending programs that support it, because it gets stuff done.

Is 18m starship a serious consideration at SpaceX? I've seen the renders but it seems like a what if and not a solid thing.

>>11943776
It's a cutaway view of the Walter HWK 109-507 motor used in the Henschel Hs 293 anti-ship missile. It was fueled by hydrogen peroxide. If I recall it's function correctly, the peroxide enters through the top, hits the cup full of reactant pellets (which are continuously fed in through that little tube in the side of the cup), the steam mixed with peroxide will full the baffles to encourage more decomposition of the propellant, and then it leaves through the nozzle generating thrust.

>>11943802
>Is 18m starship a serious consideration at SpaceX?
I doubt that it's more seriously considered than "maybe we should go back to that ITS concept?". I think SpaceX is more concerned with getting Starship to work than wandering about hypothetical future vehicles that might never come in the form they considered at the time.

>>11943802

Older rocket engines have a neat funk with their design that makes them charming to me.

Chemical engineering does have a place in aerospace engineering, at least with engine design. Understanding combustion processes is important to figuring out engine properties, and that falls squarely into cheme land.

>>11943540

>>11943823
Not really. Does it help to know chemistry when you're doing the fuel part? Certainly. Does it help being a mechanical engineer when you're doing the turbopump part? Does it help being a specialist in fluid dynamics when figuring out how to make it not go boom? Absolutely. It's a culmination of many fields.

I hate to keep bringing politics up but this is important. This problem is worse than you think. I’m in college right now at a more conservative school and most people I talk to my age (in Louisiana) love spaceflight. But I’ve severed a lot of ties with friends back in Texas. Most of my friends from high school went to UT and none of them are STEM majors, and they are all progressive liberals who actively post about NASA’s budget and how it needs to be defunded. The left is going more left and lots of normies are becoming anti-spaceflight at an ever increasing rate. It’s becoming a problem because these people vote and they want Musk and Bezos out of texas and spaceflight out of the budget

>>11943859
That's not a computer. I'm talking about the brand smth like Siemens PLCs or Bradley or some other brand with that sort of capability?

>>11943858
>What kind of control computers does a vehicle like falcon 9 use
Probably some kind of smart system with a high percentage of software, PLCs are a bit "static" maybe but idk, never seen the control system of a rocket. Lots of PID controllers though probably, they're everywhere. And we know how to tune them.

RIP public space flight

>>11943864
No, they use Linux on x86 in triple-redundant configuration. No PLCs at all.

>>11943872
I don't think pids can do that, sure they're simple to implement but they're not very flexible for complicated problems such as accurate landing sequences. That would need some sort of adaptive model predictive control which needs lots of memory to execute. I suspect they use the same computers that robotic arms are controlled with.

>>11943881
So it's just a desktop motherboard with an extra card for the analog i/o and dedicated dsp?

>>11943900
Sort of, they run the same calculations on three separate systems and make sure they all agree before proceeding.

>>11943889
>hat would need some sort of adaptive model predictive control which needs lots of memory to execute
Something like an adaptive multilinear matrix regression model? Or more complex?

>>11943889
I'm pretty sure there are at least 10 PID's for the not-extremely critical tasks though

>>11943907
I don't think so, that's too much machine learning and not enough control engineering, maybe a mix of both.

>>11943863

I have the opposite experience. Here in CA due to the pandemic all my leftist friends want more science funding and especially more NASA funding because private firms are increasingly non-functional. PG&E is the largest example which is why the state gov't can now nationalize their assets if they fall into ruin or start fires, same for a UC-owned orbital telescope and Starlink-type system. NASA requires more money to do important space things and make airliners cleaner.

Whereas, I talk to any of my conservative friends and they just don't beilive in NASA period because it's a government agency and most also don't think we went to the moon. The sort of people who absolutely hate mass transit and are upset that the state owns it's own fire plane fleet rather than privatizing fire services completely.

The F9 landing technologies are partially based off of something called "lossless convexification," an optimization approach that Lars Blackmore, a spacex engineer, did research on. I'm too much of a brainlet right now to understand this stuff but maybe it might be of use to you guys.
http://www.larsblackmore.com/losslessconvexification.htm
His seems to be on entry/descent/landing of starship now

>>11943863
The voices of some millennials on Twitter don't speak as loud as the lobbyists of the aerospace industry and two of the richest men alive. It's basically an extension of the military-industrial complex. And besides, Trump and Musk won't be the faces of American spaceflight forever.

>>11943940

>>11943802
Sure, steel has a long way to go before it reaches it's limit, consider other steel vehicles like large ships. Seawise Giant for example (up until 1991) displaced about 650,000 tons fully loaded, it's almost 450m long and almost 25m wide. Starship/Superheavy by comparison will weigh in at a maximum up about 5600 tons, assuming a full cargo load, I can easily imagine 200-250m tall, 20m wide Earth launch spacecraft, assuming that sufficient propulsion systems can be designed to lift that much mass.
>>11943863
Based LAbro, glad to know a few people still give a fuck about spaceflight. The most care for spaceflight I ever saw last semester were normies wearing NASA shirts who's eyes would glaze over instantly if I actually tried to talk rocketry with them. We're gonna make it, it isn't obvious because of the shitstorm of propaganda flooding every available piece of media but the opinions of starbucks marxists are becoming increasingly irrelevant as time goes on.

>>11943879
absolutely based
Elon is a borderline strasserist / natsoc tho

>>11943966
Those little tugs there also weigh a little bit more than Starship is aiming at and is braced in all sorts of ways.
I've worked on building ships like that, not quite so big.

>>11943940
>lossless convexification
to turn the non-always convex cost function into a convex function and thus fulfill the necessary optimality conditions and be able to numerically optimize it, I guess.

>>11943966
>assuming that sufficient propulsion systems can be designed to lift that much mass.
Using the Rocketdyne F-1's diameter of 3.7 meters, using 31 engines based on Superheavy, and an assumption that engines need 15% more diameter for spacing results in a predicted stage diameter of about 26.8 meters. 32.3 meters if using 42 engines like on the ITS.

>pressurizing the tank pops out the dents

https://www.youtube.com/watch?v=pd7eA9L6J0s

>>11943994
Yeah, I'm not entirely sold on the structural integrity of the stardineship yet. Time will tell, it's still just a prototype tank after all.

>>11943977
True, there would need to be some heavier structural reinforcement in say a double-sized Starship, but doubling the diameter of the rocket and slightly increasing it's height will greatly balloon the internal volume. Even with heavier internal support ribs to keep it from crumpling under it's own loaded weight, the dry mass fraction is going to plunge. Even Sea Dragon wasn't really close to the plausible maximum size for a steel rocket and it would have been 23m in diameter. I'd assume the real size limit would be dictated by just how much propellant mass a steel tank bulkhead can take before collapsing under the weight during say a 3G liftoff burn.
I think you'd run into the problem of needing way too many engines for it to be safe to launch before you run into the maximum possible hull dimensions.

I’m sure the aluminum rockets do the same, things will always warp when they are changing temps from 50 degrees to -200

>>11944032
It looks really dramatic right now when it's just rings of cold rolled steel. The fucking hydrolox tanks will shrink by several inches in diameter when they're filled.
Right now, the starship tank is a bit like the early centaur testing tanks and should be treated as such. Not as a rocket.

What's the chance of it blowing up? 3/4?

>>11944046
Starship/10

>>11944046
It just survived a hurricane, so even odds maybe?

What were the other sites Musk was considering for his Starship yard? It seems annoying they have to constantly communicate with the FAA and the sheriffs and close down roads and send out notices. I wish they could just fire the fucking engine whenever they please. How will they launch multiple Starships under these fucking conditions?

Also doesn’t Blue Origin also have a factory in West Texas? Where will Bezos be doing all the engine tests and stuff for New Glenn? I know they’re currently building a factory but I can’t remember where it is located

>>11944053
Huntsville, Alabama, wasn't it?

How tf can the estronaut talk so much shit for so long?

>>11944053
offshore pads to the rescue

>>11944053
Regardless of where Musk chose to make the yard he would still need to be constantly communicating with FAA and local sheriffs about it, in case something goes wrong local authorities would need to be able to quickly respond

Any renders or concept art out there of what Starship will “actually” look like? I assume it will be rolls of stainless steel welded together and a window slapped on.

>>11944141
You can forget the huge window. At best they'll slap a couple small portholes on it and call it a day.

How many of you have contemplated the eternal sleep?

>>11944144
I've thought of designs for interstellar cryosleeper ships if that counts.

>>11944147
Designs for sleep? You aren't gonna experience that.
Same as the eternal sleep, everything afterwards you're not experiencing.
Once the lights are out, you are out. Which is a really fucking weird thought, after everything it doesn't matter. You're still just gone

>>11944166
>Designs for sleep
Designs for the ships to carry the sleepers.

>>11944143
I feel like it’ll be closer to the renders than a shitty tin can. Everything Musk makes looks nice, I don’t see why Starship has to be different. Like, the cybertruck doesn’t look like a piece of shit
>inb4 cybertruck is smaller and so the steel will look better
>inb4 but Elon wants to mass produce SS anon so he’s just going to pump them out quick and they will look shitty

>>11944173
They're going for ultimate cheap. There's a reason rockets are given a coat of paint.

>>11944176
>There's a reason rockets are given a coat of paint
Yeah, because featherweight aluminum alloys need the protection. Steel doesn't, which is why you get shiny rockets.

>>11944173

This looks cool as fuck. I like the idea >>11944184 has. A shoddy starship with purple and gold heat coloring would be hilarious to see, especially if it’s routinely lifting 150 tons to space and outcompeting all of oldspace

>>11944173
The Cybertruck doesn't have visible welds and the body is made from a single piece of stainless steel that folds together. Another thing to consider is that Starship will tempered by heat and the color won't be consistent.

>>11944204
>Another thing to consider is that Starship will tempered by heat and the color won't be consistent.
Elon is going to paint a blue horse on one of the starships and GR14 is going to shatter.

God damn, Estronaut proving himself to be a low-ambition bitchboy yet again.

>>11944204
The cybertruck doesn't hold shitloads of tons of subcooled pressurized propellant either, so you can grind down welds to your hearts content and make everything nice and tidy without worrying about springing a leak and blowing up.

If Starship's reentry heat is anything like the Shuttle, it will be multicolored.

>>11944092
Australia would be better tbf. Mining companies merrily trash abbo archaeological sites that are tens of thousands of years old without much of a problem. And there's vast areas of absolute nothingness. The problem of course is balancing that with the need for suppliers and personnel

>>11944280
If I'm not mistaken the belly slam will be hotter than the Shuttle but cooler than a capsule.

>>11944280
Left, fahrenheit... right, centigrade. My american brain cannot comprehend

>>11944287
It’ll be way cooler, it’s much bigger and smoother

>>11944280
Actually, I take that back. Are there any tempering colors above 388 C? It looks like shuttle heat even on the backside was above all the tempered colors so maybe it will be consistent outside the LOX section.
>>11944288
I fucked up, I had a tempering chart with both fahrenheit and celsius but didn't include it. 1200 F = 649 C

>>11944280
would the airflow slamming around it affect the thickness of the oxide layer differently from when you're just cooking steel in the oven though

>>11944300
>Are there any tempering colors above 388 C?
not really, the grey-blue color is just the oxide layer getting thick enough to stop being transparent for thin film interference and so no matter how much thicker you make it past that it's not gonna change color anymore

>>11944308
Damn, this kills the Amazing Technicolor Dream-Rocket. I think that the oxidation builds with time as well so it wouldn't stay like that even if it saw the correct temperature range.

>>11944322
yeah tempering colors are only accurate if the piece is only heated for a short time, leaving it in for a long time at a low temperature will get you higher colors even though it wasn't heated to that point

>>11944532

>>11944532
Gee anon, no idea.
>The fact that its oxidizing ability surpasses oxygen's leads to corrosivity against oxide-containing materials often thought as incombustible. Chlorine trifluoride and gases like it have been reported to ignite sand, asbestos, and other highly fire-retardant materials. It will also ignite the ashes of materials that have already been burned in oxygen. In an industrial accident, a spill of 900 kg of chlorine trifluoride burned through 30 cm of concrete and 90 cm of gravel beneath.[19][16] There is exactly one known fire control/suppression method capable of dealing with chlorine trifluoride – the use of nitrogen and noble gases: the surrounding area must be flooded with nitrogen or helium. Barring that, the area must simply be kept cool until the reaction ceases.[20] The compound reacts with water-based suppressors, and oxidizes even in the absence of atmospheric oxygen, rendering traditional atmosphere-displacement suppressors such as CO2 and halon ineffective. It ignites glass on contact.[21]
