you terminal contrarianism is making you look like a gigantic retard. That dogshit slave camp was even more closed off then modern chinkistan is. Any admission at the time had to be forced out of them because they could not hide it in face of others observing their actions. Anything that was missed was only exposed in the 90s when there was a phase in its rump successor to at least try to at least honest with the archives. Until the KGB clan assumed power and set upon the task of rebuilding the holy empire while hushing up the bad news once again

What's the deal with Blue Origin? Why do they seem to be so far behind SpaceX?

>>15669942
They spend too much time and money on projects that don't have that much near-term utility, they're got a lot of oldspace manager types that prefer to do things "the way they've always been done," and until recently they hadn't won any major government contracts that would hold them to a serious deadline.

I hate how people refuse to accept mass expansion into space as an option instead of "no growth allowed goyim" or catastrophic biosphere collapse. I'm starting to suspect it's because they know the mudpeople they side with would be spaced for their criminality.

No one is going to be able to catch up holy shit

Hey /sfg/, what are some good textbooks on spaceflight and space systems (satellites and the like)? I recently was hired to support space things for the DoD, but my background is all applied math (they know that).

I'm wondering what are considered the 'core' texts in the field and I assumed this general would know.

I miss the deploy part of the stream. Maybe they really are putting up some NRO payloads as a bonus each time. Wouldn't the satobs people find them?

>>15670133
Space environment is good idea to start! I researched a lot about the sea system (EM, Acoustic, and Optical properties) since what I was going before this was systems in the water. For context, I am an OR analyst focused into MS&A for requirements development. I was doing a lot to support various requirements analyses, programmatic decisions, and TTP development before for systems in the water for the Navy.

Now it's I'm doing the same for space, except space is way more... Messy. Too many organizations across government imo.

>>15670140
I have heard of MINES and know a few graduates. There's a nonzero chance I go for another masters in space either from a good online university (JHU I've heard has a strong online/remote program) or to NPS or AFIT since they'll talk more classified systems. I'll look into MINES.

>>15670175
I used to support systems that went onto the LCS ships, it was insane. The program offices (that weren't LCS) were very clear that their systems could go on ships that weren't LCS if necessary and they would often times scrub briefs of the LCS to further distance themselves.

Just having to integrate onto two DIFFERENT ships was a nightmare because they're both garbage in their own ways.

>>15670176
I wouldn't be that bothered going to Mines in person anyway. It's not that far away from where I live.

>>15670186
I'm mostly pissed how while we pissed away billions of dollars and tons of resources and effort on this godforsaken class of two hulls the Chinese were busy building an actual fuck ton of blue water ships that were all more effective and capable than an entire flotilla of LCS'

In a way LCS is like SLS of the Navy, symptom of deep institutional dysfunction

I can see a justification for a capability in the littorals, there are certain critical missions to the navy there, but I can't see the justification for PURPOSEFULLY splitting resources for TWO different designs. Can you imagine if we had two different versions of everything and that they had to be equally capable and integrate across entire force designs, operations, AND share systems?

>>15670209
You're missing SpOC. But yes. It's very insane. It would be one thing if I could delineate, at least on the defense side, who does what and why, but just Spacecom and Space Force are doing a lot of similar things (there are like 4 requirements directorates in different orgs which is not normal because they don't talk enough to each other, but they're going after similar things).

Clear is so smart and clever and cute

When I was but a wee lad I always wanted to design orbital shuttles. Not like The Space Shuttle shuttles, but vehicles designed for 0g, no-atmo use, possibly built in orbit. Basically cargo frames with variably comfortable operating/living quarters, for going between, say, the ISS and some future Lunar station, maybe quick trips to the Lunar surface. That sort of thing.

Obviously spaceflight was stifled for a few decades but, is it still too early to think there might be a need for such vehicles? An advisor from Embry-Riddle basically told me there was 0 demand for such things because the supporting infrastructure was barely even theoretical, but this was before SpaceX was a twinkle in Musk's eye.

is there a timeframe or date for the next virgin galactic launch? im wondering about their expected launch cadence.

>>15669983
the hologram one

>>15670257
To date there's still no reason to make one even if there were multiple destinations. If you built a shuttle, it would need to be refueled and serviced and repaired in space, all insanely difficult tasks to do in microgravity and extremely labor intensive even with robotic assistance. The safety concerns would be pretty extreme, as without re-entry capability you're stuck on that boat until you're rescued. It's a nice idea, but you're thinking about a future where all those concerns are trivial as opposed to launching complete spacecraft direct to its destination. At best you're talking about some kind of space tug for manned spacecraft, which seems kind of redundant since they will all have their own service modules.

I could see some value in maybe providing some kind of HLS-lite for nations that can only get to LEO, but you're going to be competing with the actual HLS

How do they actually do this on the Falcon 9? They don't have header tanks?

>>15670659
The air settles the propellants for reentry and landing.
For boostback they use thrusters.

>>15670659
When they're outside the atmosphere they need to use the nitrogen thrusters to keep the propellants at the bottom of the tank, but as Anon said >>15670660
they use the aeroloads and deceleration to settle propellants once they hit atmosphere.

Why does the official ESA channel have these shitty stock footage reminders to subscribe as if they're minecraft youtubers. Are they so poorly funded they partially rely on YouTube ad revenue?

The heartbeat of the first dog sent to space was heard on amateur radio before it actually got announced by the russians. a panicked woman talking about fire was heard and nothing ever came out. the soviets airbrushed people out of photos, pretended they never existed instead of admitting something went wrong. blatant disregard for safety is how they got most of their achievements in before america

startups being short on money is kind of what you expect, even spaceX almost went bankrupt in 2008

>>15670803

Space companies should ask for donations. I think even NASA wouldn't be against budget increase. Especially as they're planning to land people on moon.

I suggest such scheme. You donate some big sum of money and astronaut on moon will read your name. For less money you can put your name on flag with many names and so on

>>15670806
vast is backed by a billionaire, so no

>>15670807
I don’t think NASA can take huge donations and just assign that money wherever they want, unfortunately
SX could do it but I don’t think any sort of donation campaign would outpace what they already make from investors, F9 profits, contracts, and starlink money
It would work well for rocketlab and astra and other “teetering on pure bankruptcy” companies

https://spacenews.com/momentus-cuts-workforce-while-evaluating-strategic-options/

> In an Aug. 14 earnings call about its second quarter financial results, Eric Williams, chief financial officer of Momentus, said that the company reduced its headcount, including both full-time employees and contractors, by 30% late in the second quarter. The move, he said, was designed to “substantially reduce our burn rate while retaining the talent we need to execute our key near-term initiatives.”

> Momentus reported a record quarterly revenue of $1.7 million in the second quarter, the first time it reported revenues of more than $1 million in a quarter. However, the company reported a net loss of $18.8 million and ended the quarter with $21.6 million of cash and equivalents on hand.

> “It is clear that we’ve faced some headwinds in the recent risk-off environment in the market, and seen our stock price reflect that,” Rood said. The company’s shares have traded below $1 for six months, and the company is seeking shareholder approval later this month for a reverse split of between 1-for-30 and 1-for-50 to boost the stock price and avoid delisting from Nasdaq. The company’s shares closed at $0.31 Aug. 15.

Very tough call to make, and one people aren't going to understand for a while. This is a repeat of the Marshall fire in Colorado last year, where any amount of water wasn't going to put out a fire being driven by hurricane force winds.

>>15670964
because the infrastructure for potable water is already in place. you need to airlift water from natural bodies and there is a limited amount of airborne firefighting vehicles and they're generally only used for remote fires away from established infra because 1) they're literally hundreds of times more expensive to operate than a regular fire engine, 2) they aren't as effective per-unit-of-water as on the ground delivery systems, and 3) the delivery rate is piss poor compared to what a regular fire department hooked into hydrants can accomplish.

the reason they used potable water first is because cities don't have any grey water systems; it's clean water or sewage and nothing in between. They used the hydrant water to fight fires at very low effectiveness, completely emptied our the reserve of treated drinking water, and were then forced to run untreated contaminated water through the same system to continue firefighting. Because they ran untreated water through the town's water supply they then needed the boil water advisory and eventually had to flush the system out to decontaminate, which is also a big headache. In the end it didn't even matter much and the firefighting was largely ineffective because it was one of those freak fires where nature says "fuck you, 100+mph winds feeding oxygen to the flames, NO amount of water will put this out"

>>15671074
NTA but interesting analysis

>>15671065
Russian Hydrogen upper stages are basically cursed, there's really no explanation lol, they've had the engines ready since 1965 but never flew any.
Fucking Fluorine upper stage got closer to flying than them.
KVTK's engine was first supposed to power an Energia upper (or side-) stage.
The indian copied the RD-56 in the 90s and managed to fly a copy of it in 2014
The italian copied the RD-0146 and turned it into a methalox engine in the early 2000s and are probably going to make it fly in ~2026 before the KVTK

Imagine the humiliation when the ****indians*** and ITALIANS are faster than you.

>>15671073

>>15671087

August 31 is the tentative date pending FAA authorisation.

Out of all RD engines ever made, which could he considered the “best”? 170 is a classic, as is 180. I’m confused about the single-nozzle variants though. There’s a lot of them. 191 seems to be the future of pockocmoc but there’s like a bajillion different variants of this engine alone. I remember an old /sfg/ thread that stated the one used in zenit 3SL (I think?) is the best ORSC kerolox engine ever built. But what goes into choosing if you should use a quad-chamber, a dual-chamber, or a single-chamber? Like what are the advantages here?

>>15671107

There are design tweaks compared to last attempt but it’s still the same overall objective (just trying to get to orbit and back)
Just like last time though, any data is useful and really clearing the tower is the most important thing. I’m hoping they at least get to successful stage sep this time. Especially because hot staging can’t be tested on the ground.

>>15670827

>>15671114
RD-107 is trusty af, how many did they make of them? 15,000?
RD-253 is definitely impressive as a large ox-rich staged combustion engine designed in the early 60s
The 170s just feels like needless gigantism that’s only a good idea for truly super heavy launchers. The Soviets or anyone never designed a rocket large enough to really need it; all its applications could have used Clustered nk-33

I like the RD-120 because it became kind of a cheap testing bed for kerozene staged combustion that everyone in the world has been using for the past 30 years
There’s a funny story of how Pratt & Whitney cucked Rocketdyne of the propulsion of the first X-34 despite Rockwell (Rocketdyne owner) having shared prime directorship of the project just because they bought RD-120 for nothing and resold it to NASA at the bullshit price or $100,000 per engine

>>15671114
The 170/180/191/etc is probably the best if you're looking at raw engineering. The 171 has the same pride of place in Russia that the Raptor for SpaceX. The 107/108 are a lot more like the Merlin; they don't have the cutting edge performance but there have been at least a billion of them made and they've built up a ridiculous work resume over the decades.

The quad chamber design was mostly because Glushko couldn't be bothered to solve large scale combustion instability like the F-1 team did, which was a bit strange considering just how autistic the Soviets were willing to get with the rest of their propulsion mad science. The fact that it let them subdivide the engine into double- or single-chamber decedents was an unexpected bonus.

>>15671183
Nice, thanks anons. I guess for Angara’s sake the use of a one-chamber comes down to common booster diameter restrictions (as in, you can’t really fit a whole ass 170 on there lol)
Is the 191 a pretty good choice considering it’s probably going to be the new workhorse for russia? I’m not sure if 191 optimizes for thrust over isp (or if it’s jsur down-the-middle) or what the differences between 191/151/181/193 are

>>15671216
>we
having a gerbil in your rectum doesn't count troon

>>15671240
• 151, lower thrust engine produced for S korea
• 181, built as a replacement for Antares “AJ-26” (really just NK-33s). The point of 181 was to be slightly more powerful than the AJ-26/NK-33s and I don’t know the specs off the top of my head but I’m sure it’s slightly less powerful than a 191 to optimize for cost because they were selling these to turn a profit
• 193, pretty much russia’s own domestic version of 181 as mentioned above. Lighter, shorter, supposedly cheaper, for future use in Soyuz 2 now that their own supply of NK-33s are being used up

>>15671216
nice falseflag trying to make pro-ukrainians look stupid, /int/ pajeets have been doing this everywhere recently. can you imagine being such a subhuman that you'd rather strawman ukrainians instead of admitting that they might just be in the right fighting for their own survival?

>>15671240
Not sure if some of these newer numbers are outdated, or exaggerated to begin with, but it looks like the 191 is a pretty solid optimization of Energomash’s long-standing bread and butter engine family

I'm trying to design a reusable 2MN class RP1/LOX engine.

Should I go for oxidizer-rich staged combustion, or tap-off cycle? Alternatively, if I used propane instead of RP1 I could use the expander cycle.

>>15671240
Diameter is an issue. Since the 171 was designed for the Zenit it's pushing the limits of what's convenient to ship in Russia.

191 is the basic model. 151 was an export model that I think only got sold to Korea once. 181 was a slightly tweaked 191 that got sold to Northrop as a drop-in replacement for the NK-33 on the Antares 200, and the 193 is a simplified 191 for the Soyuz-2-1v after Russia uses up the last of the NK-33 they've still got. The 2-1v uses an RD-0110R for thrust vector control so they proablly just pulled off the gimbling systems. All of the 171's kids and grandkids seem to the same isp listed, but you see slight variations in thrust so I'm sure they've all got some small optimizations for the role they're intended for.

The one I'm interested in seeing used is the 195, because I think that's probably a single chamber version of the RD-175 superengine Energomash was playing around with.

>>15671274
ORSC kerolox is based and russia built the 170 family with reusability in mind
They just never reused them lol

Bros... I want to see as much of the system as I can with my own eyes.

The fucking RD-170 is designed for those huge Vulkan/RLA 150...

You support Ukraine because of feelings or something, and the news told you to.
I support Ukraine because the longer they hold out, the more likely it is that this will escalate to WWIII.
We are not the same.

Don’t care about politics but we should all be thankful to roscosmos and elon musk for starting another space race that will save us all by providing unlimited funding for all the institutions we work in in the near future.
We’re all gonna be rich and drive sports cars because of this new Cold War.

>SpaceX Falcon 9 launch cadence currently avg 4 days
>SpaceX Starship/SuperHeavy aspirational launch cadence every 4 weeks

hnnngfggnngggg

>>15671398
Info on timelines is essentially just wank, and we knew the OLM caused the static fire issues already.

>>15671408
Nah the space race is SpaceX and China now. Roscosmos funding is in the shitter
>>15671398
>Orbital flight tests every 4 week
I'M COOOOOOMING

NO FUCKING WAY

>>15671408
Roscosmos is, sadly, pretty much irrelevant in the current "space race"
China is far ahead of them, and once it looks like they might actually be on track to put boots on the Moon or something, Congress will panic and the race will properly be on

>>15671422
I assume 15 is max

>>15671422
god DAMN that's an angle
also that sound did funny things to me and I may need to excuse myself

>>15671422
Woah that was gimbaled? I just thought they set the mount up at an angle. Jesus christ there are gonna be three of those things shooting at the booster for hot-staging. Also is this the first look we're getting at raptor 3 or is it an older raptor?

>>15671417
>we knew the OLM caused the static fire issues already
you're retarded. we didn't know and now we don't know because L2 is just LARP

>>15671431
maybe the plan is to fire sea levels first for separation then vacuum

>>15671431
>>15671441
Elon said they fire all 6. The sea levels will be gimbaled just like that because the dome is circumcised

>First time Starships RVac's ever light up in the air is on some batshit insane hotstaging maneuver

That's so SpaceX

>>15671424
whatever, the more countries are doing something in space the more chances the funding for space related stuff and physics and maths and etc all over the globe will increase not just the US.
Which is a good thing no matter how you look at it.

>>15671398
>Raptor issues on B9 Static Fire 1 were not due to the engines themselves

We already know they were caused by the OLM failing to start some of the outer ring engines correctly.

>We already know they were caused by the OLM failing to start some of the outer ring engines correctly.
You don't. No official source told you. There is barely anything to suggest this
>inb4 RQD tests
insane newfaggotry

>>15671462
>IFT-1 RVac truther

Even Elon deboonked it, sorry EstronautXCSI simp, this case is Closed!

>>15671398
inb4 the schedule change NASA had to "digest" was a launch every 4 weeks

>>15671468
6 RQD tests in a period of 1 day

>>15671473
Not an argument newfag. Here is them testing it 7 times before the static fire.

BASED ON 15 DEGREE GIMBALED RAPTOR

NOOO YOU CAN'T JUST GIMBAL 15 DEGREES AND FIRE WHAT ABOUT THE HECKIN DOMERINOO NOOO JUST USE THE VACUUM ENGINES TO SEPERATE ITS CLEANER, THINK ABOUT THE HECKING REUSEERINOO
