Erik Børger

>>14866850
Having secret reactionless drive vehicles would be one thing, but keeping the technology confined to a blueprint document in an airtight box buried in a secret warehouse somewhere is another. It would be like realizing a nuclear weapon is possible and then choosing to hide the discovery so that your enemies won't copy you after you build one.
The correct strategy is to build up an unbeatable military force with your overwhelmingly powerful weapons technology, then deploy it upon all of your enemies at once. The united states did well to nuke Japan but should have immediately followed up by nuking the soviet union as well, what a shame. We could have lived in a world where the US was the only nuclear power and other countries caught developing a nuclear weapon would be nuked pre-emptively. Imagine how peaceful the world would be today if the only nuclear weapons on the planet were on US navy vessels and in US missile silos. Imagine how cheaply we could end shit like the Ukraine war, Vietnam war, Korean war, etc. Literally two or three nukes and we win, not even one billion dollars spent. Ukraine war would have never happened in the first place.

>>14866860
>It would be like realizing a nuclear weapon is possible and then choosing to hide the discovery so that your enemies won't copy you after you build one.
Given the results of the Cold War I'm not entirely sure that would be the wrong decision. We can only reach for the stars properly when all the commies are dead.

>>14866832
I think you mean, why do you keep the ability to project images, thermal radiation and electromagnetic radiation to any point in space so secret you can't actually use it

>>14866850
Oh please, the government DOES keep tech secret but it’s usually just stuff like computer chip specs or information—small things. Look at the new stealth bomber coming out, they’re parading it around with a big reveal like a star whore.
If the spooks had reactionless drives they’d be launching it on an X-37 and flying it over chicoms and vatniks

>>14866865
>Look at the new stealth bomber coming out, they’re parading it around with a big reveal like a star whore.
Qualitative leaps they do keep locked up. The F-117 was kept secret from its construction in the 1970s to its reveal dropping PGMs on Baghdad in 1991. The existence of new stealth bombers aren't secret because they're incremental improvement on 50 year old technology.

It's unironically true though that if the US and Europe had undergone Operation Unthinkable and attacked the Soviets immediately after defeating the Nazis, the west would have crushed the reds and none of the follow-on cold war shit would have happened. No fear of global nuclear annihilation because there isn't a second major nuclear power to threaten mutually assured destruction. How many nuclear bombs are used militarily in this timeline? Probably more than twenty by now, but remember, the US alone detonated like 1000 nukes on their own territory (mostly underground) just to test weapons and their effects. It's not like even another hundred nuclear detonations in the atmosphere would significantly change the radiological environment of the planet.

That's trivial if you just show people the monsters the Communists really are. The real problem with this Pax Americana is that without a desperate need to outcompete the Soviets, we probably don't get the Apollo program, which means their timeline ends up being LESS advanced than ours over time.

>>14867042
I'm fairly confident in saying yes. Space has proven to be valuable commercially and its profitability will only increase with time. That will continue to drive down launch costs, which are already orders of magnitude below the 70s, making purely symbolic/scientific missions cheaper and easier since much of the technology necessary will be developed organically by the private sector.

I'm not sure if we end up less advanced in 2022, after all the shuttle led to about 30 years of near total stagnation anyway, which some have argued was a hangover from the Apollo heyday. If Apollo never happened we would have still seen Americans in orbit, with modular space stations and so forth, and probably getting more done in total by the year 2000 simply due to having slowly built upon human capsule based launch systems.

>The rabbis of the Talmud believed that the world was flat, and that the sun revolved around the Earth every day. There is a debate about the length of the solar year in the Talmud, and its consequences and the rare Jewish ceremony of the Blessing of the Sun (Birkat Hahammah) are discussed. The view of the talmudic rabbis is contrasted with that of the contemporary Greek astronomers. While the rabbis of the Talmud argued about the size of the flat Earth, the Greeks had determined the Earth to be a sphere, had calculated its circumference and had moved on to consider other questions.

>Q: I thought the point of the Black Horse was to avoid cryogens, since it uses JP-5 and H2O2. In Clapp's papers though, he talks about using LH2 and LOX! Isn't it safer to avoid cryogens completely?
>A:Well, the BH design isn't final yet. There are definite trade-offs between LH2/LOX, CH4/LOX, RP/LOX and JP5/H2O2. Currently, the non-cryogenic option seems to be the best for the Black Horse, but there are advantages to the other combinations as well. For instance, there is a better current experience base in LOX handling procedures than H2O2; there are more engine designs available for cryogenic fuels; LOX is cheaper, easier to make, and more stable than H2O2.

>>14867125
Well if you take any hydrolox stage ever designed and swap out that volume of hydrolox with a denser propellant (ie any bipropellant) you instantly get much better payload to orbit because your rocket's propellant mass has gone up by 5x to 9x. Obviously you need to adjust tank wall thickness and reinforcements plus add engines but total rocket mass correlates to increased payload to orbit, always.

>>14867139
I would rather use cryogenic oxygen versus hydrogen peroxide, however you’d need to superchill it to get the best bang for your buck and at that point you have added complexity. What is the most powerful/easily storable fuel mixture that isn’t hypergolic?

>>14867146
Liquid oxygen is not difficult to handle, that's a myth that's been held over from the 50's when we needed to learn how to move large amounts of anything cryogenic. In 2022 liquid oxygen may as well be water, in terms of how hard it is to pump and transfer and hold. That is to say, no problem.

>>14867146
>What is the most powerful/easily storable fuel mixture that isn’t hypergolic?
Who cares, you should choose zip fuel and fluorine instead of boring room temperature non hypergolic propellants.

>you’d have to add stuff to super chill it
I'm not sure what you mean by this, the lox stays cold it just boils off as heat is soaked up. The boiloff rate is very slow though, depending on insulation.

>>14867014
The 'canes feed off the warm waters in the gulf stream. I think they usually bounce off the US coast and slow down more before hitting us, like hurricane Dorian, and it's worse when they beeline towards us. Still not too worried about it, I just never miss an opportunity to shitpost.

Isn't basically that what Patton and McArthur wanted?

>>14867168
Just disregard it I’m being autistic/meticulous. My thought process was ‘well if you’re going to use LOX you might as well superchill it’

Realistically, how big can a space assembled telescope be when we get Starship working?
I guess it could be easier in certain aspects than a ground giant telescope since it wouldn't require all the support structure, and wouldn't have all the complicated unfolding of JWST since it would be assembled on orbit.

Preoxide's overall aggression is a bit of a meme. It's got a few handling requirements and it doesn't play well with organic residues, but you can clean any surface that the HTP will be coming into contact with by running dilute peroxide over it. That's actually the job most people use it for. HTP is probably one of the best non-LOX oxidizers you can get without resorting to mad science compounds. The only real problem with it is that absolutely no one sells 98% H2O2 while everyone and their dog has cheap oxygen for sale.

It could launch a monolithic 6m telescope which would be a few times cheaper than JWST

you will be proven wrong by the space industry.

>>14867199
And you can bet the first assembled one will have large delays and overruns, like JWST did as the first complex deployable. It's not a good idea to make the first one overly ambitious, demonstrate the technology first.

>>14867181
>I guess it could be easier in certain aspects than a ground giant telescope since it wouldn't require all the support structure
You still have to build it with the same stability though, and even more stable if you want to take advantage of applications which require very high stability (e.g exoppanet coronography). JWST's backpane was a major challenge technically to get something stable enough.

>>14867174
Correct, and they were right to want to do so (however wasting nukes as area denial via radiotoxic secondary products is silly, just evaporate your enemies directly and tell them to surrender after each bomb drops. Enough black eyes and even the chinese would have capitulated.

>>14867185
You can concentrate 30% h202 though.

>>14867177
On that note, I wonder how the performance curves compare between sub-cooling your lox versus adding an increasing concentration of ozone. We know that sub-cooled lox is good enough that SpaceX developed it for Falcon 9 and is using it on Starship from the start, but what concentration of "warm" lox-ozone corresponds to sub-cooled lox? If the answer is like 1%, then going to a 5% ozone liquid oxygen mixture would offer a huge benefit over normal liquid oxygen. Maybe this would be worth looking at in the future when reusable launch vehicle technology has reached a local limit of performance and someone is trying to push capabilities further.

For real though, the reason the 90's were so good was because the USA was the only superpower left, which allowed the world to be policed and kept extremely stable for over two decades.

>>14867081
That is some next level retardation.

>>14867199
When everything needs to pass through the bottleneck of infrequent, expensive launches, then yeah. That bottleneck is going away though. As launch costs decrease, foldable structures will decrease in cost too (since they can start off bigger and heavier without negative performance impact), but below a critical point the performance impact of having heavier and simpler hardware will be so low that cheap and easily conjoined hardware modules will become the preferred option. The progression we should expect is modern telescopes -> large and cheaper monolithic telescopes -> large and cheaper foldable telescopes -> very large modular construction telescopes. From the point of adopting on-orbit assembly, the limit of telescope size becomes enormous, and limited mostly by the complaints of seething ground-based observatory fags. We will be able to build space telescopes significantly larger than the Overwhelmingly Large telescope concept was.

>>14867231
It's more expensive to take 30% H2O2 to 50% H2O2 than it is to make an equal mass of liquid oxygen from air, and the lox offers better performance.

I still can't understand how it got to the point where SpaceX and Musk get heavily criticized by ruining a "natural sanctuary" like Boca Chica, killing beetles, ruining the atmosphere with co2 and whatnot, etc etc. yet China drops fucking boosters on their people and nobody gives a fuck about it except us autists interested in space lol wtf

It all makes perfect sense if you understand that the environmental movement exists for the sole purpose of crippling Western industrial/defense output. The fact that we manage to outcompete everyone else anyways is deeply shameful and humiliating to thirdies.

>>14867461
1. SpaceX is American, so they will care more about someone closer to home.
2. Musk is an adversary of mainstream media and academia.
3. Media likes Chinese money.

>>14867461
All news media is compromised, evil and corrupt. There is no 'real' news, objectivity is a myth.

>>14867461
It all depends on what's important. To the Chinese, that's the cost of progress. In the US, anyone with an interest can raise a complaint, and they will. The media reports on that, but it doesn't mean it's important.

>>14867654
The industry might be overflowing with eager liquid biprop engineers but a nitrous+paraffin hybrid is still probably the quickest and cheapest way to power something that can reach orbit. Sure, if they had more VC dollars they could design a simple GG kerolox engine but their wikipedia article says that they only have 12 people total on their payroll. They have to keep things as humble as possible.

Also, they might be willing to hire this guy >>14867502. With Astranon moving on to better prospects we need someone to replenish our roster of industry insiders.

>>14867680

>Make some noise for the BluShift High Apogees!
Yeah, I can see that.

>>14867808
This is why he was never going to be the one to lead us to Mars. His soul is too polluted with petty earther bullshit

>>14867814
We’ve got launch windows for short duration missions (26-28 days) from right now until the 26th. The 27th and 28th are long duration missions (38-42 days). The 29th is a no-go, and then it’s more long duration windows every day until October 4th. After that the stars are out of alignment until Oct. 17th when we’re back to a string of short mission windows.

There’s also recycling time issues to consider, since NASA can’t turn SLS on a dime the way SpaceX can with Falcon 9 or move it back and forth like Superheavy. That’s going to be the biggest factor besides the weather and I can’t seem to find where those limitations were posted. A scrub on the 27th would mean a delay of an undefined number of days, but I don't think it'd be long enough to prevent an attempt on the 2nd.

>>14867808
Zubrin is aware that WW3 leads to accelerated progress in space technology (due to funding and lifting of regulatory obstacles) as well as complete American hegemony on Earth, at least for a little while.
The aftermath of global war is a period of relative stability in which American imperial ambitions are high, resulting in a space exploration boom.

>>14867402

But how do they upgrade the robustness?
Weld rebar to the sides?

>>14868276
Each engine will have shielding in case of RUD in one engine during flight/return, the adjacent wont be damaged. Starship has engine out capabilities, but those capabilities arent protected yet.

>>14868398
Just to note, this is possibly a temporary solution to get the first ship success rate higher. B9 will have a more structurally engineered so that weight penalty wont be as much.

Vulcan is almost ready for flight and will remain flying for as long as Washington likes funding its friends. Neutron seems a bit further out now than it did a week ago but it’s still a safe bet to be operational by the end of the decade. New Glenn has been sandtraped by a lack of focus and funding while Blue struggles to get the BE-4 over the finish line, but that’s almost done. Once the BE-4 assembly line is operational Blur can get back to working on their own rockets for a change. Hard R is the most unreliable prediction and will probably change significantly before it happens, if it ever does.

Literally everything? Chinks are absolute shiet at building good engines and Vatnik engines are better than pretty much every engine in the world besides the Raptor.

Need hydrolox? RD-0120 for first stage and RD-57/RD-0146 for upper stages. MUCH better than chinkshit like YF-77.

Need Kerolox? Got shit for days. The whole RD-170 family and a bunch of upper stage engines like RD-0124. Only noteable chink kerolox engine is YF-100 which is just a RD-120 in chink clothes.

Need UDMH/N2H4? RD-275M and a bunch of highly efficiant upper stage engines like RD-0210 currently exist that completely mogs chinkshit like the YF-25

Russia desperetely wants to sell their engines and China might just be the right answer.

Every single American and indeed most of the world was completely in favour of giving NASA a blank cheque to pursue the IPP in full.
Unfortunately Richard Nixon was elected president and he forced NASA at gunpoint with help from the Air Force to develop the space shuttle instead.
A little known fact is that the shuttle was personally designed by Nixon with the express purpose of being as expensive and unsafe as possible.

>>14868968
Didn't Musk just say he was going to try to get an exception in Iran sanctions for Starlink to operate there?

>>14868984
The State Department probably loves Starlink v2 for that. Just turn on a region for uplink/downlink and smuggle in some ground stations and they have full Internet that a tinpot government with bad electronic warfare / SIGINT can't stop. I know if I was going to carve out a little private kingdom in the Third World I'd bring a Starlink dish, some solar panels, and battery walls as well as guns and ammunition.

I have to say it, but if Starlink violates a country's rules, then it's fair game to antisat it.

>>14869025
Who's going to stop us? There is exactly one sovereign country on this planet right now.

>>14869028
Even China would struggle to do anything to Starlink short of suicide bombing LEO.

>>14869030
Yep, China

>>14869030
Rules for thee but not for me!
The global bully will one day bow down to the tiger, mon ami

>>14869030
There are exactly zero sovereign countries on Earth.
>>14869035
Not self-sufficient = not sovereign.

bad news: it’s not like they would just missile the “iranian shell,” it’s just one big constellation servicing the world
good news: who gives a shit due to the fact that spacex can launch more on a weekly basis lol. I almost want someone to try just so the spooks give spacex a goal of sending up even more falcons and possibly even getting starship online faster (granted it wouldn’t be the durkas who would make this happen. It would be russians or chinese)

China's population peaked in the 1990s based on data from this year's ~1B personal data leak. This is as close as you're ever going to get.

My crewmate, there's this thing called wind....

rockets go sideways, if you only go straight you're donezo

>A hundred million dollars for venus photon
Any source on that?

Also, going public provided Rocket Lab with 777 million $, which they are using to buy and integrate space systems companies and develop Neutron. It was clearly a good economic and development choice.

>>14869122
No I made it up. It's more likely 30-50 million half that.

>>14869122
Rocket lab is also on the DoDs list to help develop earth to earth cargo transport for the US military. The US government needs a competitor to Space X, they don't like having monopolies

Standard price for an Electron launch is 7.5M$, add 2.5M$ for the venus photon and you have 10M$ to get to Venus. How much to design and make the payload? (developed in collaboration with the MIT)

>>14869155
That's launch costs, not the payload.

>>14869155
>add 2.5M$ for the venus photon
the r&d of that and the payload is gonna exceed the cost of electron easily.
i'm talking fully considered cost here.

>Working on an Artemis I weather story, and this comment from SLS chief engineer John Blevins really stands out: “And so, if we actually experienced a true hurricane, it would be my recommendation that we consider rolling back. Usually the footprint of those things isn’t as wide."
>It would be his recommendation that they "consider" rolling back. That's just insane. I'm sorry. It's taken NASA 12 years and untold billions to put this rocket and spacecraft on the pad. And they're going to risk it on order to kind of maybe make another launch attempt by 10/2?
