When I was a kid, I got into spaceflight from seeing cool spaceflight stuff happen. I don't get into it from watching some middle school band play. All of the outreach in the world is pointless if there is nothing physical to show for it.

whatever happened to all those display models? are they in a museum somewhere?

>>12374445
God. Looking at the plans now it's aggravating because Starship could now launch each segment at like one millionth the cost. Not to mention the fact that one starship itself has more internal volume than the entire station. I hate how NASA uses "the most expensive project ever constructed by humans" as a selling point. Not only does this piss off spaceflight fans, but it's literally fuel for the anti-space pro-welfare furnace

>>12374505
Jim Bezos

>>12374505
von Braun so far, but I think Elon in the long term. Wehrner von Braun pioneered the first experimental manufacture of very large rockets, Elon Musk will, if he succeeds in his plans, pioneer the mass production of very large rockets.
von Braun is to Musk as Karl Benz is to Henry Ford.

>>12374515
Musk also pioneered mass production of reusable rockets, but i agree if Starship is successful Musk will become the more influential person in spaceflight

>>12374505
Von Braun right now due to Saturn V. Once Starship makes its orbit, Musk for sure. His cost savings, full reusability, rapid use, and Starship will make him the man of the century imo.

boys and their toys

>>12374515
Yeah this is the best answer. I hope Von Braun is never forgotten though. There should always be a Starship named the Von Braun, or at the very least, the Spirit of Von Braun

>>12374537
This post brought to you by lori garver

>>12374528
True, but I think in the long run he'll be better known for Starship and hypothetical future rockets if it works more than he will be for Falcon. Falcon is the Model T but it will quickly be outstripped by larger rockets that utilize the same technological advancements.

You guys didn't tell me NSF was hiring cuties!

I was just at the Space and Rocket Center in Huntsville a few days ago. They’ve updated the office exhibit to look pretty damn close to the original pic (including the hole in the ceiling).

>>12374557
Agreed. Obviously rockets peaked with Redstone. And SLS is the only cost-sensible heavy lift option. Constellation was good too. I just don't see how reusing a rocket is economic over the long term. Thunderf00t is the utmost scientific expert

>>12374597
Why do you care so much about engines that were never intended to be relit? They only cared about the stage. The rutherfords are cheap prooonted shit that runs until there's no fuel left and roast themselves intentionally.

>>12374607
>roast themselves intentionally.
Yes and I want to see those mangled little bells

>>12374505
lol

>>12374620
I doubt there's much left of them after burning themselves out then passing through the wall.

>>12374607
>Wait, they're not going to reuse the engines? Wtf, how is this any better than reusing the shuttle SRBs?

>>12374585
Immortalized, untouchable, tranquil.

i dont think spacex knows how to do the plumbing for superheavy

>>12374607
You don't think they're going to try to save those engines? What the fuck do you think the point of reuse is for them, just the tank? I get that it's CF but it's still not that pricey for a small tube. The ~5m launch cost has to come from somewhere and a lot of that is in the engines.
And there shouldn't be anything keeping them from being relit and used indefinitely as long as they don't beat themselves to shit, all you do is load them with a new LiPo.

>>12374694
Saving some shit that burns itself out by design? lolno. They run until they're bone dry you fucking retards, what the fuck do you think that does to the cooling?

>>12374620
Based on the crushing at the lefthand edge of the body itself, I'd guess these poor things got smushed because the rocket slammed into the ground, not because they burned up.

>>12374692
That's why the test articles exist, so they'll learn to do the plumbing

Oh so you're a space shuttle fan?

Name every tile

>>12374600
SLS would be 20% more acceptable if it were painted in a Saturn V color scheme

>>12374724
Good meme here, desu. Gave me an audible laugh

>>12374699
So don't run it dry on reuse attempts? It's electrically driven so they have perfect control over the pumps and stopping at 99.99% of the way through just to avoid running dry on regen coolant isn't going to make a relevant difference in total dV. Again don't see how reuse would at all be justified if all they're saving is a tube of carbon fiber that probably costs ~100k or less.

>>12374666
we don't know if they're going to reuse the engines, but these aren't getting reused because they've been dunked in the ocean

it just has no grace compared to the Saturn V

>>12374749
Would you fuckers still complain if SLS had F1-B's and RP-1 instead, but still used SRB's?

>>12374744
yeah

>>12374759
Shuttle derived ones? Hell yes.

>>12374763
WHAT THE FUCK I FUCKING HATE THIS ROCKET

>>12374759
yeah

>>12374759
If it used RP1 and F1s it wouldn't need SRBs. They're exclusively there because hydrogen is garbage and the main stack can't lift itself.

Bros my O-Rings are feeling kind of chilly... do we have go for launch anyways?

>>12374767
and at less than 1/10 the cost :)

i like how orion uses the old abort system that com crew deemed unsafe lol

>>12374795
iirc it has like a 0.86 twr without the boosters

>>12374731
Most of the cost of a rocket stage is the tankage. Tanks being cheap and engines being the most expensive bit has ALWAYS been a meme.

Do you think Crew 1 will perform a flyover after undocking?

They stopped doing those after Shuttle for some reason

>>12374799
This post brought to you by a matlab faggot

>>12374811
If its not needed for mission then no. NASA wants to play safe for the first few missions. They want to minimize all extra motions for the ship. Its why SpaceX takes 24 hours to get to ISS instead of doing it instant like the Russians because NASA wants margins. Little longer but more fuel margins.

>>12374811
it's cgi

>>12374795
>>12374807
Most of the thrust of the SLS at sea level comes from the boosters.
Also, most of the mass of SLS on the pad is the solid boosters.
This means we could replace the solid boosters with liquid boosters even if those liquid boosters had significantly less thrust, because they'd also have significantly less mass. The ideal would be a high chamber pressure hydrocarbon-oxygen liquid fuel engine. For example, we could pay SpaceX to slap together two stainless steel side boosters built to fit nine Raptors each, which would let the SLS send more payload to LEO than the Block 2 configuration while still allowing for booster RTLS landing. Instead they're choosing to cut their own hamstrings and go with solid boosters forever.

>>12374810
There is no way the tank is most of Electron's 5m launch cost. If it is, they fucked up.

they should designate the SLS production facilities as national parks. they arent going anywhere, they are part of our heritage. our childrens childrens children deserve to build SLS tankage themselves. never fly of course, just keep development going forever. it would be poetic and patriotic

HOP WHEN??? WHAT HAPPENED TO SN8 YOU GUYS SAID OCTOBER

>>12374831
That is just a different bandaid over the same problem which is SSMEs and hydromeme. From an engineering perspective anyway, with Boing, NASA project oversight, and cost plus, it would end up costing billions and years of time per launch no matter what the fundamentals were.

>>12374853
Q2/21
buy some Gamestop stock and relax while we wait

Is NASA even giving a fuck to recover the SRB’s from sls? This is something I haven’t even thought about, but my gut instinct says “no, not this time”

>>12374854
If it takes this long to build one rocket, what makes them think they can even pull off ONE flight per year?

>>12374853
Static fire tomorrow for new engine. Week after that for 15km flight

>>12374865
Recovering SRBs didn't make sense in the first place

>>12374833
Tankage is most of the cost of Falcon 9, Atlas V, Delta IV, and even SLS. Rocket lab would unironically need to have had some kind of significant design/production breakthrough in order to produce the Electron rocket such that its engines were the majority of the cost, especially since those engines are likely to be very cheap per kN of thrust due to being mostly printed AND using electric pumps rather than more difficult/expensive gas driven turbopumps.

>>12374854
Oh I don't disagree, SLS is a shitshow. I'm just saying that if there's one thing we could change to make SLS at the very least be capable of putting a significant payload onto TLI, the answer would be liquid boosters. Obviously that's never going to happen, of course.

>>12374868
That’s what I’m wondering. SUPPOSEDLY they have like a majority of shit done up for Artemis III’s SLS. But I just don’t know. I honestly don’t see more than 1 SLS launching every 2 years, I’m not even trying to exaggerate or anything. Like I cannot fathom how they could have the backlog to do more than one flight in a given year

>>12374853
Need more money. Space is hard. You can't make a rocket in a tent with a box of scraps.

>>12374895
Delta IV is over half engine cost. F9 is more like ~40% at 28m launch cost. SLS doesn't belong in a sane society and for Atlas V it depends on what you factor in the solids as (which are both tank and engine, basically), with the liquid engines being 30-45% of overall launch costs. In all cases engines are certainly at least a relevant factor, falling somewhere between 30-60%. None of this explains why Rocketlab needs most of ~5m for a piece of CF that shouldn't cost more than a tenth of that or why you think that simply because their engines have some cost cutting measures that they are automatically irrelevant to the overall cost.

>>12374756
It's a shuttle chopped up and given tranny surgery to LARP as a Saturn V.

>>12374865
Anon, they're modifying historical SSMEs to slag themselves in flight and then dropping them in the ocean despite apogee being nearly GTO. Of course they're letting the boosters burn up.

>>12374954
Who in the absolute fuck thought hydrogen first stages was a good idea. I loved the space shuttle growing up. Adored it. Now I realize it was a fucking cunt if a rocket with no purpose and no grace. I always considered the Saturn V a relic from the past, but the older i’ve gotten the more and more I’ve respected it. The saturn V could absolutely fly today and would still BTFO any other rocket on the planet. And with upgraded engines and computers it could get us anywhere and would function as a good holdover until Starship

>>12374981
>Who in the absolute fuck thought hydrogen first stages was a good idea.
IIRC the shuttle's hydrogen first stage engines and the TPS made out of fairy wings and unicorn farts were because of all the bullshit dry mass penalties of the USAF modifications to the design which were basically never used. Then those SSMEs and SSRBs became "engines we already have in stock" to make the up front cost of SLS more palatable to Congress.
>And with upgraded engines and computers
Did you know that P&W pitched a modernized F-1B with less than 100 parts per engine to NASA for SLS and they turned it down? We got fucking robbed.

>>12374981
Yeah it's a mess of a problem. Shuttle had soul in the design phase but got assraped when it came to being forced to choose a final product. And then they had to stick with the shit to build SLS to keep funding. If NASA had the hindsight of knowing the future they should have done this:
• Build Saturn V for Apollo/Skylab program
• Funding cut? Okay. Build a scaled-down Saturn (instead of the shuttle) build 2 variants basically the same, 1 for a crew capsule and 1 for cargo. Call it the USL (Universal Saturn Launcher).
• Give USL a modular design. Basically for both the crew and cargo variant, everything is the same except for what gets slapped on top. Also expect for new engines to come out in the future when tech becomes available a la F1-B
• Never ever ever touch hydrolox. Don't fuck around with a spaceplane concept unless you want to do a USL dynosoar. Just keep it simple and cheap

>>12375005
Anon they could've just gone with BIG G and launched on a fucking Titan for crew. Still cheaper than the Shuttle.

>>12375005
>• Never ever ever touch hydrolox
Build a scaled down Saturn V but completely change the 2nd and 3rd stages?

How likely is it that New Glenn will succeed?
On the one hand, it's supposed to be better than any rocket currently in operation, despite coming from a company that hasn't built any orbital rocket yet.
On the other hand, SpaceX showed that it wasn't impossible for a top-tier orbital rocket to come from a fresh company, and Blue Origin practices corporate espionage.

>>12375112
ITS HOPPENING

>>12375110
If they ever get to the point of flying the thing, it’ll be a decent rocket. The contract to build BE-4s for Vulcan has likely helped focus their efforts, hopefully avoiding the constant testing seen with New Shepard. They’ve built a massive engine factory out in Huntsville to support their ULA contract, but I can’t imagine it being worth the investment without New Glenn taking up some of the engine production as well.

>>12375110
>How likely is it that New Glenn will succeed
If flying equals success, 100%
If being profitable, and selling flights is the metric for success,it's impossible to predict

>>12375110
Blue Origin will win because they followed Jeb Bush's advice: Slow and Steady wins the race!

>>12374868
It took them this long because they had to research, design and build pretty much every single manufacturing tool specifically for the rocket, since nothing they intended to do was possible off the shelf

I think a lot of people overlook how hard NASA pushes doing state-of-the-art for their own projects so other people can come in later and take advantage of their technologies after someone figured out how to make them work

>>12375110
Most of its launches will probably be for Kuiper. ULA and SpaceX have military launches locked down, and it'll need to compete with the Falcon Heavy for other heavy launches. For all the time it's spent in development, it's tough to say if it'll be worth it.

>>12375128
The turtle and hare analogy is stupid, it implies that if you're in the lead, you'll always stop before the finish line, even though the finish line is Mars, and Blue Origins only interested in racing to LEO lmao

>>12375089
>All these cute little symbols, meanwhile raptor keeps fucking up

>>12374659
lmfao

>>12375156

>>12375153
Raptor didn't fuck up on SN8, the avionics cables were cut forcing a hard shutdown. Which fucked Raptor up. It didn't just spontaneously eat a turbopump.

>>12375151
The worst part is setting up on Mars is a faster and better path to Bezos' stated plans of massive orbital construction than going straight from LEO due to the massively reduced barrier to get raw materials in orbit. It's like every decision he makes with "how do I make this slightly different from SpaceX" in mind, no matter if the result is as good or even practical at all.

Merlin by far, it's one of raptors weak points. Doubt they will somehow adapt a RP1/LOX starship, so really wondering why they are there.

>>12375480
They didn't really need to bring an entire Falcon 1 last time but they did. I kinda want them to bring Grasshopper, and put it beside Starhopper.

I’ve come back around on The Boring Company after being pretty staunchly in the ‘It’s fucking retarded” camp. The idea of making faster and more powerful TBMs through electrification and automation is a sound idea. The diameter of the tunnels is lacking but if they can build 2 tunnels at 12ft in the same time that another company can build 1 24ft tunnel then they’re coming out even.

The problem is the vehicle. The Model X is just all kinds of wrong as a mass transit vehicle. It’s a slow and inconvenient process to get all 7 passengers and luggage loaded with the current layout. What would be better would be a wheelchair accessible low floor minibus type vehicle where everyone stands and is supported by safety straps and standing seats. Way higher passenger capacity and way easier to board. A better vehicle would save the concept.

But ultimately, it really is just a poor man’s train. End blog

>>12375516
I'm 90% joking about both methalox Merlin and LMDE Merlin, but if you combine those two ideas it actually makes sense as the HLS descent engine.

>>12375521
It's for Mars.

>>12375518
The analogy only works if Elon brought TWO Falcon 1s to the presentation lmao

>>12375521
The reason for the Model X isn't for public transit, but to make private transit compatible with the Boring network. Mark my words: the small cuckpod Tesla teased at Battery Day will be Boring compatible as well, and probably uses as mass transit pods.

Eric Berger says that he had three Trump campaign sources tell him Bridenstine would have have been out even if Trump was reelected. Apparently Jeff DeWit was pushing hard to get Trump to remove Bridenstine and the campaign was receptive.

On the other hand, Berger also says that if Trump were reelected, the administration would have gone all in on SpaceX and Starship, as a result of the many SpaceX successes during Trump's first term.

Sucks if true. I understand that at the end of the day, the position is a political ends that many people are trying to get to. But god damn Jim inherited the SLS and was forced to sell it. Had Trump told bridenstine to go all-in and shill for Elon from the start, bridenstine would do it immediately. I hope he gets a job at spacex after NASA

in the 90s, DC-X had a flying prototype, capable of demonstrating the ability to repulsively land, and do in air maneuvers
and the government dropped the program in favor of the completely untested, paper rocket of the x-33, which was several times more expensive, for a prototype that never actually flew

Is SpaceX launching a rocket tonight?
I want to see them launch a rocket.

Am I stupid for not owning Tesla because I think Musk is going to start liquidating stock like Bezos to pump the Mars project soon?

>>12375682
elon will never sell his stock. that would be dumb. His net worth is up 80 billion this year for just holding it. Also, he legally can't without forward warning etc

>>12375682
an incredible level of stupid. by your logic, amazon stock should be decreasing in value as bezos cashes out a billion a year for BO

>>12375682
There's 10 more years atleast before musk starts liquidating his stock for mars

>>12375682
Bezos has to get money from somewhere, BO has never launched and once it does it has a shitton of capex to do before making back a cent. SpaceX can handle its own operations and is revving up to blow out its bottom line with Starlink operations. So the reasoning is dumb, at least.

This better not happen with Starship. Flexible launches in any weather is required. Ain't nobody got time to board a spaceship only to have to unboard because of a breeze.

>>12375702
Herzog is a gem onscreen but he should stick to movies. He obviously doesn't know what he's talking about here.

Why does the Soyuz even need boosters? Is the core stage and/or engines underpowered to lift itself? The korolev cross is fucking cool but you would have to salute them goodbye if you wanted to do propulsive landing (well I suppose you wouldn’t HAVE to, but trying to propulsive land four boosters and a core every time you want to launch a small payload would be a pain in the ass when you can just upgrade the core). Anyways yeah why does soyuz need boosters

>>12375722
SpaceX has cancelled Starship static fires because it's too windy. SpaceX is finished, they aren't brave enough to take us to the bus stop, let alone Mars

Literally the best economy and some of the best potential in the world, and America is about to spoil it because people are demanding that space is not important and politicians want to cater to the lowest common denominator. I'm fucking surprised ESA hasn't passed us up at this point. I don't give a shit if they kill NASA I've already accepted it- but if they actively start to squeeze private companies from exploring Mars I will shut down the minecraft server

>>12375646
>It's like a T-54 with half a century worth of upgrades added
Interestingly enough, someone got a hold of an old clock/timer from a Soyuz and tore it apart. The level of upgrades over time have been insane. I'm in awe that the old systems worked as well as they did.

Yep, when the top clamp lets go the long skinny rocket becomes a huge level on the base launch clamps.
Too much wind and it'll break the clamps / octoweb.

>>12375777
Checked and yes. Falcon 9 is a workhorse but it's one flaw is it's length. A light breeze can blow it sideways. While this is doesn't sound like a big deal, when you are traveling at mach bagillion it's enough to rip your rocket apart even by turning just a few degrees in the thicker part of the atmosphere. It isn't solely a spacex problem though; most rockets scrub because of this. Also Starship is being designed from the ground up to not give a shit about weather conditions.

lmao, incorrect. They installed one of their machines upside down, and another time they simply dropped a tank. Nothing about SLS is even new tech, that's the point. Sure it's got some new engineering, ie they had to make a core stage that had the same diameter as the Shuttle ET and basically nothing else in common, but friction stir welding has been a thing for a long time. For example, at the same time that they were fucking around trying to get FSW working for SLS, SpaceX was already using it for Falcon 9 construction.

Actually having no atmosphere doesn't matter, that only changes the total delta V you need for landing. If your vehicle has a local TWR of ~2 you are golden to land propulsively from orbit, any more than 2 and you're overpowered, less than 1.5 TWR and you start to lots of gravity losses. Note however that a TWR of 2 on the Moon is a TWR of ~0.3 on Earth, so even for something as massive as Starship you only need weak engines for landing.

What would the SpaceX Coat of Arms be?

took this with a canon some nights back, though it has an absurd optical zoom

The pace of spaceflight can be so slow sometimes.

Delta IV Heavy had a big HONK so they're replacing the engines

Why tf does BO have a coat of arms anyway? Maybe if they spent less time sucking themselves off and patent trolling they would have made it to orbit by now

US spacesuits are fucking sick

I think the part about Apollo that really blows my mind is how the final descent was manual. They manually landed a craft on the Moon SIX times. And somehow, without doing an unmanned test, the LM worked flawlessly on the first attempt, and every attempt since. Check out the landings after Apollo 11 if you wanna really smile.

how long until everyone are earth is counted as being in space too?

As soon as there's people on an orbital body other than Earth. "In space" is relative to the person who is saying it. Earth will be in space to Lunar, Martian, and other interplanetary colonists just the same as said interplanetary colonists will be in space to the people on Earth.

All spacesuits look fucking shit. The lack of progress in vaccuum suit technology is disgusting.
