It's one of those "everything you said is technically true but in aggregate gives an impression that is false" things, basically how CNN operates

Yes SpaceX delays and cancels shit left and right, but in the end SpaceX has put astronauts in space and Boing! hasn't. Starship is further along than Vulcan and Falcon is by far the cheapest ride to space.

rip

You're our only hope for today, RocketLab

>>12066832
It's not that hard to figure out, I'll draw a picture in and post it in a minute. What's hard with propellant cross-feed is actually trying to get reusability to work well with it; cross feed is a great way to end up with a center core that goes waaay too fast to survive reentry without a lot of TPS.

>>12066952
>It's not that hard to figure out
People with degrees in fluid dynamics would beg to differ, but by all means. Draw a diagram in paint to convince them otherwise.

>>12066932

AHAHAHAHAAHAAHAHAHAHAAHAAHAHAHAHAAHAAHAHAHAHAAHAAHAHAHAHAAHAAHAHAHAHAAHAAHAHAHAHAAHAAHAHAHAHAAHAAHAHAHAHAAHA the absolute STATE of spacex

>>12066956
Just wait for the diagram. SpaceX didn't do it because reusability was a better thing to optimize for (reducing cost of flying real payloads rather than bloatmaxxing for the biggest possible theoretical payload), and ULA didn't do it because it would cost money and the government didn't give them a giant cost-plus contract to do it.

>>12066963
I'm sure you can name the superior alternative

>people think it's scrubbed
They literally pressurize, depressurize, and depressurize the tank to press that fucker before every test lmao

>>12066952
you're not getting that center core back if you do cross-feed

>>12066978
tbf did we not spend all of last night spamming AHAHAHAA DELTA LMAO RESULTS OVER RHETORIC AHAGAHAHA

everyone shitposts on a scrub, getting defensive is pointless

>>12066980
repressurize*

>>12066983
ULA doesn't really have an excuse for that, since Delta IV is a finished rocket, not a prototype

>>12066988
every rocket is a prototype if you throw them in the ocean when you're done, show me a delta that's flown more than once

>>12066983
no?

>>12066983
Delta had a post lite scrub, which means they can't launch it for another week or two lmao

I WILL HOP WHEN I FEEL LIKE IT MOTHERFUCKERS

AAAAAAAAAAAAHHHHHHHHHHHH

>>12067009

>>12067009
It appears to be some form of arithmetic.

ITS OVER.

>>12067030
they will try again in some hours

>>12067009
Seems like a double integral of a paraboloid over a rectangular region and then a matrix that could be lagrange multipliers for an optimization problem?
Idk I can't read shit. Seems like calc 2 stuff.

>>12066982
Exactly why SpaceX didn't do it

>>12067048
but think of the LIFT

>>12067009
Musk is obviously insecure about his lack of credentials because Musk haters bring it up every time they try to dismiss his accomplishments, so he's trying to rewrite the narrative about his academic history to prove that he has a formal education. He just wants to stop the "he just hires smart people" comment which I imagine is pretty annoying.

>>12066952
Crossfeeding would be better if you had a lot of heavy shit to move up in one go. Could probably get the ISS up in 4 trips. Then again so could starship.

>>12067053
he's absolutely a smart dude but his main skill is absolutely bringing very smart and motivated people together to get real work done

>>12067053
But he does have a double major in physics and economics and a masters degree.
Why would anyone bring this up to diminish him? You would have to be literally retarded.

>>12067056
Actually crossfeed works the best for getting lots of delta V, if you're trying for max payload you end up losing a lot of performance to gravity losses as your TWR decreases.

>>12067029
>>12067044
It's very clearly a calculation of the moment of inertia tensor

>>12067067
... of something. Dunno what.

So no hop today?

>>12067067
Idk, I'm not a physics fag.
The only clear thing here is that it is ink on a paper.

He could only get good people working for space x once it was already successful. He couldn't even get a good chief engineer in the beginning and had to do that job himself.

>>12067079
>It's a meaningless jumble of foreign characters if you're not a math guy.
Math major here, I have a general idea of what it is but can't really read it.
Physics fags have sloppy and gay notations.

>>12067089
yeah that too

>>12067071
Pad cleared again 10 minutes ago.

>>12066988
It’s a shame to because I still remember watching orion EFT-1 launching on that

>>12066952
>What's hard with propellant cross-feed is actually trying to get reusability to work well with it; cross feed is a great way to end up with a center core that goes waaay too fast to survive reentry without a lot of TPS.

This. Crossflow stopped making sense the moment that reusability became possible.

>>12067116
What a shame it never had its chance in the late 60s.

>>12067119
Neat. Hope to see the inky blackness of space with my own eyes before I die.

Remember what they took from us we could have had a shuttle-buran mission

>>12067121
Crossflow would have been god-tier for the Space Shuttle. Imagine the Lockheed pregnant whale shuttle sandwiched between a pair of expendable hydrolox boosters fueling the orbiter via crossflow.

Crossflow would have been peak oldspacekino in the 70s through the 00s and probably would have become the standard (instead of booster/sustainer) if the USSR had gotten it's shit together and greenlit the UR-700 for a 1970-1972 flight.

The UR-700 would have given the Soviets the perfect opportunity to one-up Apollo because it would have had the launch capacity to fling a Salyut-sized hab module to the lunar surface. Imagine if instead of saving face via Salyut, the Russians had been able to instead save face via sending cosmonauts to a series of Salyut-style lunar surface stations for months at a time.

Today in history:
>1871 – Ernest Rutherford, New Zealand-English physicist and chemist, Nobel Prize laureate, is born (died 1937).
>1931 – Jack Swigert, American pilot and astronaut is born (died 1982).
>1984 – STS-41-D: The Space Shuttle Discovery takes off on its maiden voyage.
>2004 – Fred Lawrence Whipple, American astronomer and academic died (born 1906).

>>12067125
The US should have paid the 1990s Russians to reactivate Buran and Ptichka and build a 3rd as part of their ISS support.

>>12067012
>this is ULA's idea of reuse

>>12067135
Then to up the UR-700, the USSR would then build the UR-700A which could carry up to 250 tons (predicted). Following that, an even more massive UR-700M for what I guess was for a Mars shot and could lift 750 tons into space.

Honestly so mad we never got this.

Getting close to buying parts for my first hybrid motor. What diameter case should I get? The max I'll go for is 2 inches.

>>12067150
1.875m

>>12067135
>a pair of expendable hydrolox boosters
HISSSSS
In all seriousness, if you're gonna do Shuttle with cross-feed, you don't need to bother fucking around with hydrolox anymore. It makes more sense to go for the easier-to-handle propellants because you don't have the ridiculous per-stage delta V requirement that turned real life Shuttle into a booster-sustainer. Ergo, methalox space whale orbiter flanked by twin methalox boosters, propellant crossfeed, and eventually, reusable booster propulsive landings.

going back to ethanol rockets WHEN

>>12067164
>Ergo, methalox space whale orbiter flanked by twin methalox boosters, propellant crossfeed, and eventually, reusable booster propulsive landings.
Are you trying to turn on everyone in this thread?

Whoops. That's 2 hours 29 minutes. Not 2mins 29 seconds.

What kind of shuttle could you launch with F9's instead of SRB's?

>>12067249

side vent

>>12067245
During his stream of the Tianwen-1 launch, the chat was spamming memes about communist Chinese atrocities, and instead of doing the sensible thing by saying something like "I'm not interested in discussing politics, I just want to see rockets fly." he tried to excuse said atrocities.

>>12067249
Technically the F9 did launch the X37B shuttle

>>12067249
F9 only - Dreamchaser.

>>12067249

>>12067255
Its like spamming memes about capitalist american atrocities on native indians...

>>12067255
He did no such thing! He said talking about politics wasn't what he wanted to do in the stream.

You are under no obligation to like Tim,but don't fucking lie.

Link to him excusing Chinese actions right now or fuck off.

4ASS's first orbital test article.

>>12067564
>"The concept for the Ariane Ultimate, pictured left, is a fully reusable Single Stage To Orbit, including an integrated fairing, a very high percentage of the 3D printed components, and hugely simplified ground operations, to the point where it can take off from a basic flat landing pad. Some ideas presented even include exotic, high-performance fuels, such as polymeric nitrogen."

>"Currently, it’s a topic researched for the post-2040s timeline, fostering many developments along the way aimed at reducing costs and increasing flexibility of not just the launcher, but the supporting ground infrastructure and the industry behind it all."

Don't take anything about that rocket as real. It's a hypothetical study.

>>12067574
>Currently, it’s a topic researched for the post-2040s timeline
The fuck is the point, just speculate on warp drive shit it's all the same.

>>12067581
Shit is studied well in advance all the time, man. Just be aware of what it is. They're working on stabilizing polymeric nitrogen now for instance. If you know your organic chemistry, you know that nitrogen-nitrogen bindings is some really energetic shit.

>>12067586
Single bond nitrogen-nitrogen bond = ~160kJ/mol, triple bond nitrogen-nitrogen bond = 1MJ/mol. That's the highest potential energy binding found in nature outside a nuclear explosion. Stabilize that and use it as rocket fuel and you can should easily hit 450 Isp monoprop in theory at least.

>>12067545
This should honestly be meme’d way more than it already is. They are suggestion a monopropellant that reaches ISP levels of a hydrolox engine lmao. Might as well put a warp drive or a reactionless engine on the second stage

>>12067591
>suggesting
fuck

Idk my gut tells me that Starship will be able to handle these winds normally, once it’s finished of course. I just don’t think elon wants to risk it with his prototype. Better to launch it when the weather is nice so you don’t get an unexpected failure.

Delaying a test by a day or two is way better than having the thing explode from some unforeseen weather and needed to rebuild from scratch

>>12067741
Well yeah. Why would you not want favorable conditions across the board? Although its not like things haven't exploded during a optimal test.

I store my propellant in bottles on the shelf.
And I need to pick up some new ones soon.

That's not your gut. You either read it from Elon's tweet or read some info on Starship design specs.

>>12067791
With an ejaculate specific impulse of 1.27 seconds, you would need a mass ratio of over 1.8e305. Assuming your dry mass is the average human male mass of 87.6 kg, that would mean the propellant mass would be 1.61e307 kg. Which is over 1e254 times more than the total mass of the observable universe.

Taking ejaculate density of 1000 kg/m3, the total volume required to store the propellant would be 1.61e304 m3. Split between two spheres would result in the diameter of just one of those to be 2.49e101 m, or 2.63e85 lightyears (note that the observable universe is 9.3e10 lightyears in diameter.

So in order to ejaculate into orbit, you would need more cum that there ever is in the universe with testicles that are so large that they can store multiple universes into them. The mere act of orgasm would be so vast that it would be impossible for a human to perceive it in his or her lifetime.

think im done with spacex bros, all scrubs and biting off more than they can chew, at least with Boeing and NASA we know what we're going to get.

iirc it ends with a failure to ignite for deorbit, stranding the one girl in LEO. Then the backup pilot gets flown on a second capsule and guts it on the spot to make room for the stranded pilot and they splash down together.

>At T+72.284, the right SRB pulled away from the aft strut attaching it to the external tank. Later analysis of telemetry data showed a sudden lateral acceleration to the right at T+72.525, which may have been felt by the crew. The last statement captured by the crew cabin recorder came just half a second after this acceleration, when Pilot Michael J. Smith said, "Uh-oh."
>In Mission Control, there was a burst of static on the air-to-ground loop as Challenger disintegrated. Television screens showed a cloud of smoke and water vapor (the product of hydrogen+oxygen combustion) where Challenger had been, with pieces of debris falling toward the ocean. At about T+89, flight director Jay Greene prompted his Flight Dynamics Officer (FIDO) for information. FIDO responded that "the [radar] filter has discreting sources", a further indication that Challenger had broken into multiple pieces. Moments later, the Ground Control Officer reported "negative contact (and) loss of downlink" of radio and telemetry data from Challenger. Greene ordered his team to "watch your data carefully" and look for any sign that the Orbiter had escaped.
>The crew cabin, made of reinforced aluminum, was a particularly robust section of the orbiter. During vehicle breakup, it detached in one piece and slowly tumbled into a ballistic arc. The forces involved at this stage were probably insufficient to cause major injury.
>At least some of the crew were alive and at least briefly conscious after the breakup, as three of the four recovered Personal Egress Air Packs on the flight deck were found to have been activated.
>Some experts believe most if not all of the crew were alive and possibly conscious during the entire descent until impact with the ocean.
Talk about irl nightmare fuel... who develops a crew safety feature to survive then not have any method of slowing it down for water impacts... they trained the fucking crew to swim and no-one asked about the cabin itself surviving a water impact...

>>12068642
>he doesnt stack some parachutes on the crew module

>>12068646
The Shuttle was a mess.

>>12068642
I don’t see why the couldn’t have made the crew cabin it’s own pressurized module, and added at least a parachute on it. Literally would’ve been as easy as placing a wall at the back of it with the rest of the orbiter. I’m not even talking about an abort system I’m just talking about making it it’s own pressure vessel with a parachute.

>>12068655
too complex, would have delayed the program
please understand

>>12068642
I wonder if they could have bailed out if they were wearing the later LES suits. Probably not enough time for all of them to do so.

https://www.youtube.com/watch?v=QCuPgk3Ml4M

>>12068642
The more I read about the shuttle the more I question how it came to be in the first place. That thing was so dangerous

>>12068698
Basically Congress wouldn't keep funding the Saturn V, Nixon killed the actual useful parts of the STS architecture like the Saturn based nuclear space ferries, and then the Air Force stuck their dick in the whole process insisting on single orbit pass snatch and grab capability that gave us the clusterfuck of the eventual design.

>>12068698
To be fair it was not dangerous when the engineers could ensure the shuttle launched under reasonable conditions but the NASA administration and upper contractor management were so desperate for launches that they went out of the recommended launch conditions thinking they were somehow more knowledgeable than the men who built and tested the rockets, the biggest scandal being Challenger with NASA administrators and Morton Thiokol managers intimidating and overriding the engineers into launching well out of spec of the SRBs capability and the subsequent attempted coverup until hero's like Allan McDonald spoke up and uncovered the entire shitshow.

Remember to occasionally clean your rockets.

>>12068926
Why don't they clean them anyway? Doesn't that soot cause drag and add a little weight?

Launch when?

>>12068934
no, it's not soot it's singing

And once they did something out of spec and it didn't fail, it essentially became the new spec.

>>12069147
here's the rest of that report

>>12069056
Yeah I was wondering this too. By the time Elon is (supposedly) launching dozens of starships a day, will a countdown even be necessary? They don’t give countdowns for plane takeoffs. I suppose they will give the crew a 15 minute countdown or something because you’re gonna want to be seated and strapped in by the time those engines let loose

>>12069147
Astronomers should know their place. The future now belongs to engineers and geologists who will be zipping around the solar system and setting up constellations around each habitable solar system body.

>>12069147

>>12069147
As a satellite enthusiast, fuck the stars

>>12069141
neat

>>12069152
Unlike planes, rockets have little margin for course correction, so some sort of launch window is necessary, and it can become especially narrow of you want to meet or avoid something already in orbit.

Well the recommendations are sound actually. If everyone and his mother launches his own constellation when the kg/leo price goes way down it will be a clusterfuck.

>>12069342
Yeah I agree, there needs to be a limit at some point. Obviously bezos will do it. I’d imagine it will help him expand amazon servers and whatnot. And pretty soon every schmuck is going to want their own satellite and their own constellation.

>>12069147
How come "astronomers" attack satellite constellations but not their very own bugman cities for light pollution?

>>12069342
We need to get past this awkward phase to a point where astronomers will be able to use multiple kilometre wide telescopes in space. With a few being maintained planetside as backups and possibly historical landmarks.
