How that didn't lead to an all-out shooting war I will never know.

>>14813078
Korea

Just had a dark idea, that if SLS blows up, falcon9 gets grounded too because congress will demand a "indepth investigation of the american commercial space program"
And call me crazy but they are spiteful in that way.
>if we can't have it, nobody can.

>>14813078
Same reason why the dutch didnt start a war with russia over malaysia airlines.
Cooler heads prevail when russians start shitting the bed.

>>14813078
Nobody wanted one
the fun of the cold war is that both sides planned to use nukes early, and both sides knew it, so neither side had the cojones to press the button

>>14813080
Falcon 9 would never get grounded from that but also boing would still miraculously pull through as a company despite adding a spaceship on top of their double airplane kill count.

>>14813086
There were some Soviet invasion plans of Europe in which they hoped that by not nuking any nuclear Western power, only the Germany and such with tac nukes, the West wouldn't go full ICBM.
But those were military plans and can't be set in motion without political approval.

>>14813080
they might suggest that and MoD then promptly tells them to fuck off because they want their sats up
somebody sensible could also point out F9 is the most reliable rocket ever

Newspaper headline
>SLS was rushed out of fear of "unfair"&"hostile" competition from spaceX's billionaire elon musk, claims congress.
Musk hating normies would eat that shit up.

>>14813078
It was a mixture of human error and confusion. The flight was never meant to fly over the Soviet Union, and so defense bases there thought it was an American spy plane, fired warning shots (which the pilots presumably didn't see), and after they made no change in heading or communications, they were shot down from beyond visual confirmation range.
Keep in mind that 1983 was a second height of the cold war, both sides were on the edge

>>14813096
even if they only went tactical, the US also planned to immediately use tactical weapons of their own
it'd be a rain of hellfire on both sides with fuckloads of escalation potential
and that's before adding on the fact that both sides had different opinions on what a tactical target was, and what a strategic -worthy of ICBM response- target was

>>14813080
lmao Trump lost, get over it

>space stations
>fuel depots

>>14813117
Shut it down!!!

>>14813117
Space Station Freedom was supposed to include a propellant depot as well as a megawatt or so of solar power from mixed PV and dynamic and a full orbital shipyard. In the 90s. We got robbed HARD by the end of the cold war.

>>14812949
>Russian Space station
Yes, a downsized ROSS is achievable, if only to save face, but since module completion will probably slip into the mid 2030s it means they'll either have a period without a space station or they'll be left operating their part of the ISS alone after the US has switched to a CLD station. The proposed 98 degree inclination means reusing modules like Nauka is unlikely and undesirable in general because it's so outdated.
>Orel
Wouldn't count on it launching anytime soon. Anatoly Zak has said the development effort ran into a bunch a problems and it's been repurposed for LEO operations, which would effectively kill Russia's lunar plans, not that they could afford to do anything besides a flyby.
>Potentially the first missions to outer planets?
I doubt it, TEM is obviously dead or on the back burner. I can't find when was the last time Russia flew an RTG but presumably it would require a brand new development effort. Science missions are lower priority now and the war has slashed the funding of Roscosmos.

>>14813146
Freedom station was only going to work if the space shuttle delivered on what they promised at the beginning of the program.
So blame the people who screwed with the shuttle program.

>In a 1991 interview with Izvestia, Major Gennadiy Osipovich, pilot of the Su-15 interceptor that shot the 747 down, spoke about his recollections of the events leading up to the shoot-down. Contrary to official Soviet statements at the time, he recalled telling ground controllers that there were "blinking lights".[40] He continued, saying of the 747-230B, "I saw two rows of windows and knew that this was a Boeing. I knew this was a civilian plane. But for me this meant nothing. It is easy to turn a civilian type of plane into one for military use."[40] Osipovich stated, "I did not tell the ground that it was a Boeing-type plane; they did not ask me.

Whataboutism aside, accidentally killing civilians while taking out a target =/= having all the signs that it's a civilian plane and withholding information to your superiors so you can take the shot.

>Honestly, HLS is a huge fucking win for SpaceX and it doesn't require either the booster or Starship (HLS) to land. If they make it to orbit, and then fail in a spectalular fireball, which I'm expecting, it's actually quite a minor setback. There's a lot of wiggle room to figure out reusability, as long as the launch side works.

If they get starship into space, can they refuel it? Do they attach big booster and refuel it for it to go to mars?

Are the static fires justly causing confidence? Is there a coming up launch and land date attempt?

Is there a try to get starship to orbit date?

If starship was gotten to orbit, they wouldn't think of trying to reenter and land it right? Because they barely landed it from 30,000 ft.

So if they got starship to orbit, what would be the plan?

Does an HLS exist yet, whens it planned to launch?

Is starship going to plan launch and land attempts to incrementally higher altitudes?

The US finished our post-Vietnam overhaul of the military and Moore's Law started kicking in big time. Think about the Gulf War - all of that tech was available in the mid 80s, and Saddam's army was the closest thing we ever saw to Soviet equipment and doctrine in a straight fight after the NVA. Reagan knew full well we'd kick their asses in a conventional fight and used that to bring Gorbachev to the table for nuclear arms reduction talks.

KSP is very popular among a certain niche audience. It is also an incredibly shitty game. It seems like the shittier it got, the more popular it got (or possibly vice versa). I find this to be very strange. I guess it's a case of there being no real competition within that tiny niche, so a terrible game can be successful since there's nothing better.

you may enjoy Jerry Pournelle's stories written at the height of detente
>The point of departure of Pournelle's history is the establishment of the CoDominium (CD), a political alliance and union between the United States of America and a revitalized Soviet Union. This union, achieved in the name of planetary stability, reigns over the Earth for over a hundred years. In that time, it achieves peace of a sort, as well as interstellar colonization, but at the price of a complete halt in both scientific and political evolution.
>The CoDominium (CD) is a supranational alliance of the United States of America and the Union of Soviet Socialist Republics. This alliance eventually becomes a de facto planetary government, and later, an interstellar empire. Despite this, no other nations on Earth are given representation or membership. Other major powers become mere client states. It is governed by a "Grand Senate", which is composed of Senators chosen from the two superpowers. A CoDominium Council exists and appears to function as a judicial branch. The CD did not unify the United States and the USSR, who appear to retain their separate identities and mutual distrust. The CD was only created for the shared benefit of the two member states. It does not govern either nation, and each state has been allowed to retain their government structures, nationalities, militaries, and to run their own internal affairs.

KSP is both one of my favorite games of all time and also one of my most hated. Few games have so much potential but are so fucked in the technical aspects that it completely undermines any ability to actually get at the good bits in a satisfying manner.

If KSP2 doesn't actually fully fix the technical aspects it'll be dead in the water, regardless of how many new systems or QOL features they cram in.

>>14813392
A 6 engine RD-270 powered Saturn V first stage (assuming the same gross stage mass, adjust dry weight and propellant masses accordingly) would get a thrust increase of ~3800 kN along with a sea level Isp increase of 38 seconds, over the original F-1 powered stage. Once in the upper atmosphere the RD-270 powered stage would have an Isp advantage of 18 seconds and would be producing ~1400 kN more than the original stage would at that point. Note: this basically means that the RD-270 powered vehicle would be getting a much better TWR off of the pad, at a very significantly higher Isp, compared to the F-1 stage, and should have got much better performance to orbit as a result.
If we instead used the RD-270M for the same purpose, the thrust would be slightly higher still, the Isp at sea level would be 77 seconds higher than the F-1 powered stage, and most importantly of all the exhaust flame would be a brilliant emerald green color because the engine runs off of pentaborane fuel.

>>14813377
>half a decade
We had about two years, one of which was spent demobilizing from WW2 since many of our men hadn't seen their wives since 1942. The baby boom which happened when they got home cemented our demographics for the next 30 years so that was the right call. Then a couple of Jewish spies gave nuclear technology to the Soviets in 1948 less than three years after V-J day.

>>14813418
If the RD-270M was reusable that would have been cheap enough to allow the Saturn-Shuttle design to work with the same Orbiter+payload we actually got IRL and a foam-on-the-inside ET, meaning neither of the fatal Shuttle failure modes would exist. It'd be wildly toxic for handling but it'd be the best possible booster engine performance until the Raptor.

>>14813397
Right now the problem is that the game's popularity vastly exceeds the expected popularity when so there's a situation where you have a genuinely popular game with huge amounts of newly added features that rest on the foundation of what was supposed to be a niche borderline indy game, which means bugs and extreme jankiness. KSP2 has amazing potential because it will have had a proper development and engine, even before considering any new content.

>>14813262
>having all the signs that it's a civilian plane
I guess that's what infinite war tensions can do. Having an infinite evil enemyz allows you no other option but play it safe on your terms. An enemy plane is unscheduledly loitering in your space.

Why could communications not be made to the plane?

It is interesting how it comes down to the individual pilot, would a different pilot have resulted in different outcome. What percent of pilots would have acted one way or the other, was it just unlucky draw trigger-happy pilot who happened to be having a bad day was the one who got called on

>>14813535
>The whole reason they went with droptanks and SRBs was for faster development
It was because the STS design we got was expected to cost the least to bring to the table. It ended up going way over budget anyway and couldn't meet its own scaled back launch targets, let alone the original program goal targets. We would have been better off if Shuttle was cancelled completely in the early 1970s and America was left high and dry for half a decade scrambling to fill the gap.

The fact that NASA was more interested in flying Big Gemini on Titan instead of Apollo on Saturn I as an alternative to the shuttle blows my mind. How is Titan cheaper????

>>14813639
Because they were churning titans out on a factory line for the US ICBM fleet so in theory would be easier and cheaper to mass produce for space missions.

>>14813639
Volume produced. Piles of ICBM Titan IIs were rolling off the same assembly lines. It's the reason why the Long March 2/3/4 are so cheap.

cleaning out the OMS pods on the shuttle was a pain in the ass between flights. having a massive fuel tank for main propulsion would make that a thousand times worse.

>>14813487

>>14813671
FUD, this is what Shuttle refurbishment actually looked like.

>>14813657
It's like that with guns, too. Most Soviet firearms were complete trash (Mosin rifle, Nagant revolver, Tokarev, Makarov, SVT-40, etc. etc.), but once they got the SKS and AK factories dialed in, they could produce excellent rifles for ridiculously cheap unit costs.

>>14813674

>>14813680
>metallic TPS working
some to think of it, why isn't spacex using this instead of the tiles?

>>14813689
Expensive and complex. Maybe they will use it in the future.

>>14813689
It required retarded superalloys from what I've read, whereas the ceramic tiles can be mass produced in the millions for cheaper. For Starship it makes more sense to go with the tiles since they're uniform and sturdier than Shuttle tiles.

>>14813689
something something pores clogging

>>14813688
it's so wild that one rocket company has roared so far ahead of everyone else. They've been landing and reusing rockets for 5 years, to the point of it being routine, and the nearest competition to this day is still a ways off from their first test launch of a reusable orbital rocket.
When the fuck is new glenn supposed to launch anyway? BO have been awfully quiet for the last months aside from the occaisional sad tourist stunt.

>>14813680
The Soviets had an unfair number of genius designers. If they hadn't been hampered by corrupt resource allocation and pointless political drama the cold war wouldn't have even been a contest.

I've always wondered if the shuttle could have been improved by using a disposable ablative heat shield. It'd have to have been better at tanking a debris strike and unbolting and replacing 5-10 panels would be a lot quicker to turn around then hand inspecting each individual ceramic tile. It'd be another kick to the balls for the idea of the shuttle being reusable, but with the external tank being disposable and the boosters barely refurbishable it's not like anyone would really notice.

>>14813713
Possibly, but on the other hand those tiles were some badass engineering, so yay.

just wait china will have re-usability everywhere

>>14813713
The tiles needed replacing so often anyways that they should've been considered semi-ablative.

>>14813639
up through the 1960s hydrolox stages required more expensive sensors and equipment to monitor the propellant. saturn ib's IU was basically the same as the saturn v's, so it was overbuilt for a smaller rocket and that also drove up the cost. the titan SRBs were also stupid cheap before they changed from PBAN to HTPB and went from the TVC and gimbaling nozzles.
>>14813646
is correct too, the USAF was already paying to keep the titan production lines open. nasa had already decided to go with the titan IIIE for launching deep space probes in the mid-'60s before the budget cuts hit because it was so much cheaper than saturn ib-centaur would have been.

Lori Garver:
>The mandate to lower the cost of space transportation set in 1970 by President Nixon was to reprioritize this “massive concentration” of energy given to NASA, in favor of developing “low cost, flexible, long-lived, highly reliable, operational space systems with a high degree of commonality and reusability.” Just imagine what could have been accomplished by now if NASA had accepted and successfully delivered on this mandate as it had its previous goal to beat the Russians to the Moon?
>Instead, NASA leadership designed the spacecraft they wanted to build, prioritizing internal interests and parochial constituencies instead of embracing the assigned national political mandate. In my view, we have been working the wrong end of the problem—putting the cart before the horse. Programs that require large amounts of taxpayer funding must be guided by established valuable purposes. The cart must follow the horse. Building a big rocket or going to a specific destination aren’t ends in themselves; they are means to an end.

>>14813674
how much did this cost compared to just manufacturing a new one?

>>14813616
Ultimate counter is to say Raptor is better and cheaper than anything the Soviets ever built

>>14813731
Fake news. It's well known at this point that Nixon single-handedly killed Apollo, designed the Shuttle himself and forced NASA at gunpoint to build it, and there's even enough evidence now that shows he's the one responsible for sabotaging Apollo 13

Our alloys right now can only withstand an Earth reentry from LEO if the vehicle they're shielding is a super low density hydrogen balloon like Venture Star was envisioned to be.
Metallic TPS would definitely work just fine for a Mars-only reusable launch vehicle though.

>>14813702
They are goals driven instead of profit minmaxing driven, which ironically leads to them being more profitable, because they aren't afraid to spend money making a truly improved product.
Also BO will never do anything, they are going nowhere

>>14813713
>I've always wondered if the shuttle could have been improved by using a disposable ablative heat shield.
Improved in what regard? The eggheads would have found a way to make the single-use shield just as expensive and complex anyway, somehow. That's what eggheads do if you don't whip them to keep them in line.

back during the dolphin sex phase they were planning on hydrolox for the OMS and RCS. i'm guessing the budget crunch meant they didn't have any money to try developing new tech for orbital maneuvering once they actually started work on it.

Each orbiter was like a billion dollars to build.

>>14813752
>side mounted oxygen rich turbopump assembly with big U pipe
Many such cases, sad.

>>14813713
There was a proposal to have the Shuttle use an ablative heatshield in it's early flights when it became apparent that the tiles were going to be a far bigger nightmare to work with than imagined
http://spaceflighthistory.blogspot.com/2020/01/no-flying-brickyard-1972-1973-plan-for.html

>>14813778
and according to google the launch cost for the whole stack was 450 million
so I guess they did save some money by reusing it (if you ignore the possibility of using another system entirely)

>>14813777
They could have been planning to use hydrogen and oxygen gas from the internal propellant tanks in a hydrolox gas-gas OMS engine, which would actually make sense. However, when the Orbiter was redesigned to use and external tank instead of built in propellant tanks, that idea would have to be replaced with internal liquid hydrolox tanks instead, and that probably wasn't worth it.

>>14813750
I lold

>>14813787
>if you ignore the possibility of using another system entirely
That's pretty much what every shuttle fan does. They argue that at least we still had something, which implies they don't know about the Titan, Atlas, and Delta rockets, nor the fact that NASA had designed and built human space capsules just a decade earlier and could have done so again for the purpose of doing everything Shuttle did (ie, fuck around in LEO and then "help" build the ISS by restricting the American module sizes and masses).

I would say most other companies are not only profit minmaxing driven, but do this on very short timescales, even quarter-to-quarter which then leads to much worse profits on longer timescales
optimizing for profits on a longer timescales could lead to similar actions, I mean SpaceX does usually start from trying to get some minimum viable product so they have cashflow to continue
even starlink has profits as an instrumental goal to support the longer time goal of mars colonization

>>14813817
>I mean SpaceX does usually start from trying to get some minimum viable product so they have cashflow to continue

>>14813817
in this vein, boeing and lockheed not giving ULA the money to develop ACES for vulcan just looks stupider all the time. if the rumors about starship ditching the heatshield for early flights are true then the tankers are just going to be giant ACES stages. ULA would've had a huge headstart on spacex and probably would have been able to submit a competitive HLS bid if they'd been willing to drop a couple of billion dollars into R&D back in 2010. but they controlled the american launch market and they assumed things would stay that way forever.

It's a bunch of PR twitters doing one word summaries today. Fidelity's was "stonks".

Please explain gravity assists to me like I'm a retard.
I just don't get how they can lead to a net increase in velocity. The gravitational pull acts on the spacecraft as it is "outbound" too, thus negating any speed it gained on approach, right?
I can see how this alters the trajectory, but where does the acceleration come from?
From what I could gather so far, I'm guessing that this has something to do with different frames of reference, but that's about as far as I got.

>>14813873
>I just don't get how they can lead to a net increase in velocity.
The body being orbited slows down ever so slightly.

>>14813873
Essentially the spacecraft is pulled by gravity in the direction of the planet, increasing its velocity in that direction. After it leaves the sphere of influence of that planet and the force of gravity becomes negligible it will retain that increase in velocity. It might help you if you realize that it also effects the planet's velocity by a *very* small amount.

>>14813789
looks like that was the idea with the RCS, although the OMS was just going to be RL-10s with separate tanks. hilariously, they call the RCS system a low-risk development.
they were also planning on doing autogenous pressurization and modifying the jet engines from the DC-10 to burn LH2.

>>14813883
wrong pic, here's the RCS for the booster

>>14813873
>The gravitational pull acts on the spacecraft as it is "outbound" too
Yeah, but it doesn't cancel the force out, unless you're flying straight through the planet.

>>14813873
if the planet was perfectly still with respect to the sun then all you could do would be change your trajectory, but it's moving.

>>14813873
The planet is moving too, so the acceleration is net in the direction of the planet.

So that exoplanet has a ridiculous surface gravity of 117m/s^2.

Afghanistan was a center of heroin production. Heroin was then muled through asia to USSR , and also sold in USA for billions. Billions ended up in dark money pools and London and NY banks. The dark budget was also used in part of financing dark glowie operations against USSR and countries of Warsaw pact.
USSR moved into Afghanistan to cut out billions of drug money. Of course it was taken badly by London, Swiss and NY banks and it didn't end well for USSR.

Science and space exploration could've massively benefited. Instead, bankster and drug mafia got yet more money and power and we are barely scratching the surface of scientific exploration.

how do nozzle extensions maintain sealing between the primary nozzle and deployable extension? I'm guessing there's some acceptable amount of leakage?

>>14814202
Multiple Jupiter masses yet not a proportional increase in radius equals higher gravity. It's only about 3.5x Jupiter's gravity anyway.

>>14814213
Well the gasses are already moving down at like 3500 m/s, so there's not really any backflow to leak. The nozzle extension simply seats into a lap joint and the gasses press on it like a 360 degree wedge as they try to expand radially, accelerating them linearly.

Why is there so much shitty "science-fiction" schlock that gets greenlighted these days? Everything is just a normal TV premise with an amateur depiction of spaceflight.

>>14814295
CGI is cheap, so you can make "unique" drama by giving it a sci-fi framing device even if it sucks

>>14814110
Wouldn't Earth with no moon be a bit smaller and have a different stable precession? The Theia collision basically created a binary planet so of course it needs both halves to be stable.

Reminds me of the fact that Proton was originally designed as a "Super Heavy ICBM", and was designed to carry a 100 Megaton (or larger) yield nuclear warhead to anywhere in the world.
Tsar bomba was 50 Megatons, this shit was an apocalypse-tier weapon system

Animation of Artemis I around Earth - Frame rotating with Moon

>>14814552
non rotating frame

>>14814557
it's like we're playing fetch with the moon

>>14814517
the destructive power of big nukes is dramatically smaller than you think they would be
the destructive power of a nuclear device is the cube root of its explosive power, and is bound by the inverse square law on top of that
a 1MT device isn't 1000x stronger than a 10kt one, its 10x stronger, but uses dramatically more fissile material
despite being able to make big fuck off nukes for decades, the strategic arsenals of the world remain in the 150-350kt bracket, with only a rare few 1-5MT devices in stock between them

the fact that nukes can indeed be intercepted and are not 100% reliable to begin with just makes having a small handful of big cojones even worse compared to maintaining a swarm of reasonably sized ones

So, hypothetically, what will happen to the Artemis program if Artemis 1 is a failure?

>>14814571
Then the private lunar endeavors that follow will thoroughly embarrass NASA and Congress, potentially to the point of SLS being canceled and the program getting reconfigured to rely almost entirely on spacex

>>14814571

I never can tell how many orbits they plan to do around Earth before TLI

The timeline suggests they're going to do less than four orbits, maybe even less than three.

Good morning

>>14814642
It's going to be less than one. Remember the TLI stage is the tiny ICPS with one RL10. That means the SLS core has to do most of the work and launch the ICPS+Orion to a highly elliptical orbit.

>>14814652
oof, they need block 1B so bad

>>14814659
They might actually get to Block 2 by Artemis 4 at this point given the delays are allowing booster+EUS dev to catch up.

>>14814652
Not even. They have to dump the core in the ocean, so the ICPS also has to get itself into orbit.

>>14814664
I thought they were doing a deorbit burn after that which is why people were proposing wet workshops.

what's with biden's new twitter intern?

>>14814576
Reminder that the reason that FH is not man-rated is Elon decided it wasn't worth spending the money to certify it. If that happened, NASA would be the one paying.

>Lost on this day: Alpha
>it has yet to refly

What could cause NASA to change their Artemis plans? This program is extremely dissapointing when compared to Apollo, that is five decades old.
>launch every two years with the goal of annual launches (and not every mission will land on the Moon) vs two landings per year
>a week to reach Moon vs three days
>SLS<Saturn V
If nothing happens, they're going to waste a whole decade fucking around with their 4 billion dollar orange rocket.

How many more times can they fuel the orange tank before it surpasses the maximum allowed before risk of brittleness?

>>14814921
Their plans would change quick with a spectacular Artemis 1 RUD. They can't afford to do another "test" flight. Some failures might be excusable enough to proceed with Artemis 2 as planned, but SLS pulling a Challenger would pull back the curtains on the program's ineptitude and force Congress to slash Artemis funding.

>>14814921
Realistically? No RUD required? No budget cuts to the direct program? The new tower. The future of the program requires the replacement tower, and we already know per the OSIG report that the tower is 400 million dollars behind without even a finalized design. If that tower takes say, two or three years longer than anticipated? The program is dead. Or say, outside chance, the new Block explodes on the pad and does a ton of damage to it? That'll kill the program. Especially if SpaceX is making serious progress with the Starship in tandem with these developments.

Apparently the Raptor swap on B7 took under an hour. Lol.

HE CANT KEEP GETTING AWAY WITH IT

>>14814936
It's over muskets, he will never get it under half an hour like he promised

>>14814921
A lot of Artemis is defined by congressional contracts, so it’s really a question of “what would make congress want to stop spending money on its friends?” If HLS can go from LEO to the moon and back on one tank of gas, they’d stay the course, but if SpaceX uses that to sell an all-European or all-Japanese moon mission to ESA/JAXA they might consider it. Most explosive problems wouldn’t kill the program; they’d just delay it with the possibility of an expensive redesign.

>>14814925
That tower is going to be a huge problem.

>>14814925
Good point actually anon. Given everything so far, no fucking way they will build the other tower in time or on budget

>>14814936

>>14814912
>Nani?
>What are you doing?

>>14814959
>>14814953
The OIG report stated that the tower won’t be done till at least 2027, so Artemis IV is NET 2028.
I know Starship has its delays but I’ll eat my hat if it isn’t flying regularly by then

>>14814896
It's such a big dick move to demonstrate pin-point landings on only you're second attempt of sending guys to the lunar surface. It's kinda sad how NASA thought this was a necessary thing to perfect early on in order to pave the way for the more advanced lunar exploration that was sure to follow the initial Apollo missions

I am obsessed with fat upper stages

>>14815009
Also here’s a comparison of the “original” Prometheus IRBM with the Prometheus-K in my current career. The Prometheus IRBM, also called the Prometheus A, had a range of 4000 kilometers. The Prometheus K is just a horribly upgraded version with a fat hydrogen upper stage designed to lift Apollo capsules into LEO.

>>14815009
>>14815023
Fat upper stages are a fun challenge. Try some SRB's too

The environmental impact study on the Indies and any other potential destinations has been delayed due to technical difficulties. We estimate it will be finished a few decades after global trade networks, sufficient advances in biology and medicine, and exhaustive satellite imagery make the task feasible, some time in the 21st century. Please understand. It’s not that easy in environmental impactry.

spacetime is an abstract idea of a coordinate grid.
