NASA:
>celebrating/congratulating CNSA launches
>sharing CNSA data with their large international audience
>getting excited when the CNSA rover operators get excited
>watching over CNSA rovers like fans, tracking their progress and commending their successes
>generally being kinda pissed at the law that prevents NASA from cooperating with CNSA, especially on space stations
>knows how difficult rovers are; seems more upset at other agencies losing rovers than losing their own (Insight, though a lander, was riddled with instrument disasters and nearly a complete failure several times - NASA didn't seem all that fazed by it)

CNSA:
>if we don't say anything, maybe NASA will forget about our rover

a rover failure is nothing to be ashamed of, it's happened to... i think literally every agency that's tried rovers at least once. it's a part of the experience.

>>15220840
Chinese face culture is a MESS.

I've heard a few times now that ion thrusters have improved significantly in the past few decades, but I've yet to see any spacecraft that use any kind of improved thrusters in any meaningful way. It could be that I've just failed to notice them, but what makes newer ion thrusters any better than the older ones? Are they more efficient, do they provide more thrust, or is there no actual significant change?

>>15220869
Gateway

>>15220869
It's mostly cost and power efficiency gains so far. Gateway will be the biggest electric thrusters put to serious use so far.

>>15220878
People actually think Gateway will happen? Lmao

>>15220893
Yes?

>>15220869
The Dawn mission is one of the only missions that has leveraged their high specific impulse in a useful way. It visited 4 Vesta and Ceres.

>>15220869
Greatly reduced cost is another factor. At some point station-keeping thrusters on new satellites switched over from hydrazine to ion, and falling costs had to play a big role in that.

>>15220840
>a rover failure is nothing to be ashamed of
That's not it.
CNSA doesn't have a public-facing culture, they lag in openness, outreach, and accessibility vis-a-vis other space agencies.
The first reports of Tianwen-1 entering Mars Orbital Insertion actually came from amateur radio observers rather than their official reporting. They even play(ed) whack-a-mole to take down unauthorized livestreams of their launch.

>>15220893
They're repeating the ISS trick. Macron already inquired about getting a French astronaut onto Artemis III when he was in the US. They're dangling seats/module contributions in front of the UAE. ESA/JAXA/CSA have more or less set their astronaut recruitment programs around the Artemis Program, and so on. Unless Artemis II explodes, Gateway is happening.

What's the catch with plasma spallation tunneling? Surely Boring Co would explore it if it had promise.

>>15220786

>>15220893
there's alot of value from gateway. we need to learn how to do space stations outside of earth's protection.

>>15220869
Haven't heard of Hayabusa, Dawn, BepiColombo, etc? Electric propulsion has been only growing in popularity, it's used for orbital maneuvering on many satellites like Starlink and has become the most ideal way to transfer from GTO to GEO while conserving enough propellant for years of operations. It hasn't yet extended to manned missions because there isn't much funding for it, slow acceleration isn't ideal for gravity wells, and it requires not only a large amount of power but that with a high specific power which is a greater problem than the thrusters themselves. Gateway will be the first attempt but it's still more or less a proof of concept. Reminder that there are moons in our solar system that cannot be reached by chemical propulsion even with refueling at Earth Moon L2 and/or Mars orbit
>>15220982
Manley says that he is going to work with the developers to provide the voiceover for the tutorials. Hopefully that will limit the would be Kerbal-fuckers created by the game.

>>15220955
>What's the catch with plasma spallation tunneling? Surely Boring Co would explore it if it had promise.
It uses fuckloads of power. That's the one big downside.

They stuck some random literal who black guy between Scott Manley and Matt Lowne at that ESA sponsored event they had, I wanted to give him the benefit of the doubt but then I watched his commentary and the smoke alarm low battery warning was constantly going off in the background.

Scientifically speaking, how are they able to just ignore that sound? It drives me fucking nuts within a few minutes, there must be some type of black excellence at play.

the best starter telescope is a 6" or 8" solid tube dob, definitely get the 8 if you have the space for it as it still fits perfectly across the back seat of a car and is easily carryable
at 8", you're mostly limited by light pollution in what you can see. In dark skies you can see galaxies down to about magnitude 14. They're just faint grey smudges at that point but you can make out some shape

>>15220869
The chinks are using it right now to keep their space station up
>Tiangong space station is fitted with conventional chemical propulsion and ion thrusters to adjust and maintain the station's orbit. Four Hall-effect thrusters are mounted on the hull of Tianhe core module.[75] The development of the Hall-effect thrusters is considered a sensitive topic in China, with scientists "working to improve the technology without attracting attention". Hall-effect thrusters are created with manned mission safety in mind with effort to prevent erosion and damage caused by the accelerated ion particles.

It was a spacecraft from the 1970s that was in the same weight class as some of the next gen vehicles we're planning now. The Soviets had issues, but it's wild how far ahead of the curve they could aim sometimes.

>>15221071
How much improvement has modern imaging techniques brought to scopes that size compared to ye olde analog astrophotography?

>>15221089
We can achieve 5-meter resolution from Earth with a radar telescope, and that's just a prototype.
https://greenbankobservatory.org/planetary-defense-science-will-advance-with-new-radar-on-green-bank-telescope/

>>15220941
What is the point of having a non-military space program if you keep the entire thing secret? To get good science out of it, it needs to be transparent, and the political benefits obviously need public engagement.

>>15221099
The prototype was just 700 W, and they are building a 500 kW system.
Imagine the details.

>>15221089
the biggest benefit vs analog photography is probably being able to seamlessly take set exposure lengths (30 seconds, 5 minutes, whatever), and stack them digitally to maximise detail and brightness, and being able to discard subs that have flaws like satellites or clouds in them. Dobs aren't really good options for astrophotography though, something on an equatorial mount is needed for optimal tracking

test?

Before Raptor, the record for highest engine chamber pressure was the RD-701 but just before it, it was a German-designed Hydrolox Closed cycle engine developped In the late 60s in collaboration with Rocketdyne and tested in 1968

>>15220982
I don't like the implication that kerbals can speak english, they need their own unique gremlin noises like the old Chatterer mod had.

>>15221106
there's also the trick of being able to stack frames where the atmosphere is briefly still to get sharper imaging than analog could ever reach

>>15220893

No voice changer works this well, we've been over this before, but you pretend like the past conversations never happen and just repeat the exact same shit as before, very autistic

Also this thread discusses Erryday astronaut so Clear absolutely does belong too

I've literally never had this conversation before, you don't understand that everyone who isn't completely insufferable and intent on sucking off the e-penis of an e-celebrity wants you to shut the fuck up.

There isn't a point. The moment any Chinese non-government aerospace company reaches a point where it becomes a threat to its military industrial complex, expect Xi to come sweeping in and basically taking it over to incorporate into its military to lock it all down. They want the Musks of the world to come in and foster innovation in their market, but they'll make 100% sure that they'll never let another Musk grow into power internally for two reasons:

1. They don't want lip ala Jack Ma
2. They want to 1000000000% ensure that this person never becomes a threat to the party in power.

Incidentally, good chance, this will doom their Moon/Mars colonization efforts as an inevitable rebellion will occur when the parties on the Moon/Mars realize that they can breakaway and turn themselves into another Taiwan. Because space, moon, and Mars, for all intents and purposes, is international waters and whatever Chinese sovereign law that may exist on Earth doesn't translate into space as a result of the international treaty regarding space.

which makes it even more impressive what they achieved. I mean in another work nasa should be stuffed mostly by russians.

Meanwhile the russians, im not going to even go into the twisted dream of collectivisim, which tough i don't support at all is much more complex that the binary on off capitalism/communism idea most edgy teens on both sides like to make it look as, but they were seriously tied up in that, with much less resources, losing a very serious cold war, having most of their scientist figuring out how to efficiently distribute potatoes along all of siberia of all shit, and having just a handful of the most fanatically compromised with their craft scientist, the only ones mad enough to risk getting shot by a crazy political officer to go trough, and they were under inmense pressure, anyone else would have quit, but they seriously mcguivered the shit out of it, it was obvious they were gonna lose, but i think any accomplishjed american who knows hard work would respect them if they knew what they went trough.

get your shit straight Iron Dome is an Israeli system for shooting down ww2 era missiles. It's got nothing to do with this guy here:
https://en.wikipedia.org/wiki/Ground-Based_Midcourse_Defense
which is prolly what you were after, and is also prolly more than able to shoot down incoming one or two missiles, specially if its one of the shitty ones like from china or india or something, russia i wouldnt bet on it, they are broke af, but they dont mess around with the thing that is keeping them alive, and also more than 50 years of rocketry experience is not nothing to scoff at
keyword here: ONE OR TWO, this system would be able to shoot down one or two missiels, maaaybe 5-10 certainly nothing more than that.
ICBMS have an apoggee of around 1000km and re-enter with a speed of mach 20. When youre getting more than 100 or even 500 or even 2000 of those at once there is just not stopping them, sorry sir but mr laws of physics is just heavily disagreeing with you regarding your idea of "2000 50 ton object coming down at mach 20 being able to be intercepted safely" no sirr, thats just not gonna happen with this set of univcerse law, maybe next universe tough.
thats literally why MAD doctrine exists, why usa has to put up with the insane bullshit of russia, dont you think they would have glassed them if they could. why do you think hey didnt? morals? get your head on straight kid, youre leaving the most existing, probably the last moments of mankind on earth and youre not even paying attention

i don't know man, weirder things have happened, i have the feeling that they are gonna ar least attempt to launch it.

i mean its so fucking weird
picture 5-10 years ago the basedstronaut was a thing right? (dumb filter btw) but he was just some random dude being skinny and reading wikipedia back at you on youtube, while we all waited on SLS to launch within our grandkids lifetime because we believed "space is hard" but now were getting ready to see a mars base asteroid mining moon youtubers and interplanetary walls on our lifetime, truly weird stuff

>>15221680
youre not a genius, youre particularly dumb because you didnt even bother to learn wikipedia level knowledge of space flight
getting altitude is a very small part of getting to orbit, the biggest part is going sideways fast enough not to fall back to earth aka orbit. God damn why am i even explaining such basic things, its like attempting to educate a 40yo man who doesnt know the difference between the asshole and the vagina, at that point why even bother

however, there is a little merit to the blimp idea just not how you think about it
https://en.wikipedia.org/wiki/JP_Aerospace
you could technically make a "gigantically mind blowinlgy hugely huge" blimp and have it go to the edge of the atmosphere, then accelerate very slowly while bouncing over the outermost layer of the atmosphere until it gets to orbit. Its a hugely retarded idea barely possible theoreitcally and almost thorougly impossible from a practical point of view at least with current technology/incentives, but i thought id be fair and let you know the extremely small and aproximate fact of reality that was at least vaguely similar to the obscenely wrong and retarded thing you said of which ou should be ashamed of even in anonimity

i gota admit, the whole concept does sound cool, like it almost deserves its own "punk" aesthetic cateogory, i mean it would totally define a world if you would be waiting for a blimp to get you to blimp station so you can get a faste rblimp.

alas, when you crunch the numbers its wildly unrealistic, even with obscenely high launch cadence, evenm ore so than spaceplanes which are quite unrealistic as they are.

it looks like reusable rockets are the answers, with maaaybe an intermediat period of launch loops or something similar then a huuuge time till space elevators reign but like literall hundreds of thousands of years into the future

>>15221710
the thing is bang per buck. If you could "somehow"(this is the tricky part that will take thousand or even hundreds of thousands of years to figure out, and it might even to come out to how to develop a society stale enough to realize guarantee no one attempts to sabotage it) make it so you really have a space elevator that works, and besides mantainance all the energy it expends is just mantaining the counterweight in orbit as the cabins go up slowly controledly that is insanely efficient.

insanely meaning between 50 and 20% more efficient than the next best thing, which might not be much if youre only sending like 100 tons per decade like were now but once youre sending like 10 million tons per day to orbit that difference adds up real quick and whatever kind of global communism facism capitalism star trek hippism or whatever it will be just too fucking juicy and tempting to resist

>>15221724
>10 million tons per day
A single space elevator wouldn't come anywhere near that. You'd be sending relatively tiny payloads crawling up the endless cable for days.

This is a precursor to that tech, the "electric booster" part.

>>15221731
fair point, i mean if it were up to me i like reusable rockets more, i just think space elevators are simultaneously completely retarded given todays technological paradigm but also kindof unavoidable given a (very) long time span. At least on smaller bodies like the moon but most likely on earth too

>>15221737
I don't find far-future stuff nearly as interesting because by the time it is practical we will probably have some new understanding of the physics and will have even better ways of doing things

>>15221723

You'll probably have networks of fairly short tethers orbiting all over the place for providing delta-v to passing ships.

>>15221753
Someone in 1923 probably would have a pretty hard time imagining the practical applications of integrated circuits, let alone that they would exist. I get that things are harder now because all the easy stuff got figured out, but when you start talking thousands of years I think that makes up for slowed advancement.

>>15221753
>t. (((Einstein)))

>>15221756
The IC one is a good example, if you watch some videos on ASML machines and the outrageous amount of high-level physics and engineering that has been put into developing machines to make chips, it makes me wonder what else could be made with similar engineering efforts in other fields. If Fusion had the same kind of capital and brainpower dumped into it in a private development setting that IC did, I have 0 doubt we could be running the planet on fusion by now.

>>15221747
>some new understanding of the physics
that is an interesting question but there's nothing to indicate it will happen, or that it wont
i mean we have "some" evidence that theres more going on taht we know, but its just as likely that it makes no difference and that for all intents and purposes the current known laws of physics are all we get and all improvements we can make are only in the realm of engineering which is not small thing but still its limited. Basically its the FTL discussion.
So to sum it up its a super interesting question

100.000.000 million years in the future, will we be energy cubes made out of pure pleasure that just make an unmake trillion light year 10-dimensional structure just for fun...

OR we coudl get something thats basicall some sort of space "punk" dystopic alien/blade runner future in which we reach a certain treshold and it just stays like that for millions of years as humanity kinda forgets what was their homeworld becuase the same mundane worries that plagued early man (food shelter safety sex etc) follow him unrelentlesly to the stars

>>15221779
It seems kind of unlikely that right now just happens to be when our model of everything is almost complete. Historically it seems like all the cool discoveries take everyone by surprise, and I see no reason for the surprises to stop now.

lol

>>15221790
>It seems kind of unlikely
not quite, i mean , for thousands of years everyone had like an ooga booga religion superstitious way of understanding the universe, once we got scientific rationalism for 100-300 years its reasonable that we maxed out on the rules of the univers, particularly becuase what we learned so far is that its a quite simple and fractal universe, theres not a lot of different stuff, there arent like millions of elements theres a couple of hundred, and all of them are made of a couple of basic molecuels, its not very glamorous but it checks out with all of our models. The idea of permanent advancement has no basis on reality and i dont see any real reason to expect theres some great unexpected rule of the universe we've yet to find out about other than we wish it to be true

Does anyone think this is going about the wrong way? These people are talking about launching the next gen telescope 20+ years from now. Its insane.

Shouldn't we be pushing for rapid launch candence with technology led approach? Why are we only going for "mature tech" 11+ billion dollar single launch event? Why not 11 launches of 1 billion each? Why not 100 launches of $111 million projects?

>>15221796
I don't think its going to be completely massive and change completely everything we know, but I also think that there are still plenty of loose ends to tie up that will probably lead to more questions, and whenever new physics drops there is always the chance that some of it is practical

You're absolutely wrong. You are no different from the Christfags who were stopping Galleleo. "The idea of permanent advancement has no basis on reality "

We know there are holes in our understanding of the universe, there are clues but we just dont have the tools/budget/means/time to verify our assumptions in any meaningful timescale. The problem isn't that we've hit the limit, the problem is we've hit the limits of our civilization's capability to progress due to rising cost in labor/shortage of man hours/short timespan of human life/limits of normal human brain/etc.

Think beyond the horizon of a human limits. We're just in a bigger well, the gravity well.

>>15221811
>. You are no different from the Christfags who were stopping Galleleo
i think its fair to say im a little different. Christfags were like "no everytrhing is like so because sky daddy told us".
current laws of physics are more like, 200 years of hundreds of thousnads of insanely bright people arguing based on logic and reason.

I mean , the reason its so powerful its because anyone who takes the effort to learn can understand how it is.
Like
2+2=4? do you understand that? well, thats the laws of the universe,saying we'll some day find a way to make wacky physics its like saying well find a way to make 2+2= maybe watermelon or maybe abstrac concept. I'm not saying it wont happen, im just saying its not very likely and literally 100% of all experts agree with me

>>15221800
Obviously. Astronomers lowering their standards to such a piss poor level embodies the oldspace mindset
>oh JWST ended up costing 10B? 10X more expensive and 20 years late? welp I guess that means the next big one will cost 10B and take 20 years!
These retards actually think this is being "conservative". in reality their little pet project will take 40 years and cost 100B if we let them try. HWO or the Carl Sagan Telescope should be cancelled and all funding must go into solving quantum error correction so visible light interferometry can be achieved, paired with mass production of space telescopes. everything else is pointless masturbation

>>15221819
Its also based on observation, and some observations cannot be made, have not been made, or are interpreted in an incorrect or incomplete way

>>15221822
*cannot be made for practical reasons

>>15221822
fair enough. You might realize i don't say its unlikely well find new principles of physics, im just saying its unlikely as it would go against literaly everything we know, which includes all of the knowledge that powers all of the machines we know.
but pure reason allows me to understand it, just because i throw a pen and it falls down 10000000 times out of10000000 doesnt mean it wont fall "up" on the 10000001 time

>>15221737
lunar space elevators cut down that nasty delta v penalty for getting to/off it

>>15221827
Your logic is flawed, the principles that govern the pen have been well established since caveman times: thing go towards planet

Now you can waste much more money dropping smartphones, whose cost comes from internally machinery governed by some random shit discovered long after pens were invented.

>>15221796
>its a quite simple and fractal universe
>it checks out with all of our models
I don't think you understand the state of affairs in physics at all.
The incompatibility of GR and quantum field theory is our Ultraviolet Catastrophe
Speaking of which, we have actual Ultraviolet Catastrophes all over the place, we fix them with Renormalization which means "sub in the measured value"

>>15221832
this was a fucked analogy, but my point is that current observations will have to remain true if physics ever changes. otherwise it wont be a valid change in physics. Future physics would explain things not yet explained, like how caveman physics cant explain the internals of the smartphone but it can explain why its smashing into the ground

>>15221819
>Christfags were like "no everytrhing is like so because sky daddy told us".
Not really. The church was like

>>15221832
>>15221832
>Your logic is flawed
no its not, its literally based on the basic laws of logic, if you believe in a logical universe im right. Like, im saying 2+2=4.
also you might have caught that i dont deem this to be necesarily true,maybe the universe ISNT logical, but if it its, then 2+2=4 theres no amoutn of argumental gymnastiscs that could make you even convince 0.0000001% of my fellow ivy league atendees that theres 0.00001% of something right in what you say.
If youre arguing for an ilogical universe, then sure, it may or may not be, and i dont discared it, but in a logical univeres i buttr rape you into oblivion in this discussion, like, in a particularly bad an humillating for you way, i win ;)

A total revolution in physics wouldn't have to go against everything we know. It would just be a new perspective. General Relativity reduces to Newtonian Gravity in the weak field limit.

>>15221800
>Why not 11 launches of 1 billion each? Why not 100 launches of $111 million projects?
The recent decadal did recommend funding for a new line of probes, Kepler sized missions at around 1 billion. But the rate is quite low, one per deacde. And it's only x-ray and far infrared. Formalising the probe line was a good move, but it didn't go far enough. It's one of the weaknesses of the decadal system. In astrophysics every bigger than a MIDEX has to be prioritised in the decadal, but small missions can rarely compete for science with the huge concepts so they get pushed out.
It's actually something that ESA manages much better. In the ESA system there are small, medium and large opportunities. The concepts compete in a fixed cost envelope, rather than the decadal system. In the next decade they will launch Euclid, PLATO and ARIEL, which will be transformative.
There is however the case that in the US the budgets are not fixed. Funding cannot just be redirected to small missions, because they are separate lines in the budget from Congress. There's no guarantee that if they moved to purely small missions that funding would be conserved.

>>15221821
The problem is that JWST is huge success. And if you compare it to Hubble and correct for inflation, Hubble also cost about 10 billion before launch (not including service missions and operations). JWST was a programmatic disaster, but it was still about as efficient as Hubble. The people at fault were NASA HQ, who deluded themselves into believing it could be done for much less.
>solving quantum error correction so visible light interferometry can be achieved
Visible light interferometery already works, it's just extremely limited. Optical/infrared interferometers are very niche instruments, they have tiny fields of view and poor sensitivity. They're not going to replace telescopes like Hubble and JWST even in 50 years. ESA is considering building a mid infrared interferometer to detect habitable planets.

>>15221847
This. Everyone else is underage and should shut up and read a book.

>>15221849
They do do like the angels seed investors do. Fund 1000 projects with $100-$10M each. If one of them even breaksthrough with their investment, it will more than make up for any "losses" on other investments.

Obviously they shouldnt be blind investments, investments should be based on the character of the leadership (those who can get things done regardless of hardship, with records of exceptional talent), feasability of the projects, scope of the project, timeframe (1-4) years rather than decade long projects, and a clear goal driven by hard metrics. Along with added bonus for if they're able to commercialize it, thus making their business case sustainable.

>>15221849
what is it that we don't yet know about the universe. I mean, what is the next big thing we could discover with probes?. Like, ohhh a planet 10 ly away might be 80% cadmium instead of 70% like we thought of originally. Is there anything really interesting we could discover or is it just detail fetishism on distant rocks that make no diference?

>>15221849
>The problem is that JWST is a huge success
Tell me about it. Faggot fuckers are legit all in on LUVOIR/Keck-esque foldout segmented mirrors at this point, it's embarrassing and reinforces really awful paradigms. Honestly dont give a shit about cost, it's the wasted time that's truly tragic. should be 10 years tops per massive observatory, and many smaller ones should be launched in the interim.
>Visible light interferometery already works, it's just extremely limited.
yes, it's shit, and existing method dont scale.

>>15221858
>what is it that we don't yet know about the universe
Lol
It would be easier to name the things we DO know
It would be short

>>15221849
i heard or read somewhere that NASA and ESA tailored their approach to complement the other so that all types of missions are covered

>>15221858
Refer to this >>15221847 retard

>>15221858
We have a lot we don't know and what we do know is probably all wrong. We're building a jenga tower out of things that barely make sense on their own and make no sense put together.
Expect current cosmology to be ripped out by the foundations in a couple of decades.
If you're afraid all the research's been done and all the things discovered, you really shouldn't be.

>>15221858
If there was an Earth-like planet 10 ly away it would probably still be unknown completely. So yes, being able to detect it and characterise it's composition in extreme detail would be pretty fucking transformative.
Things that are currently unknown which could be studied with probe missions: the abundance of Earth-like planets and the best targets near the Sun, the potential habitability of M dwarf stars and the atmospheres of their planets, the origin of supermassive black holes, the accelerated expansion of the universe, the first generation of stars, whether inflation happened, which galaxies reionised the universe and how did it proceed... quite a lot I'd say.

Why is it whenever I hear detractors talking about Warp drive propulsion they always talk about destroying the target location? As if any civilization capable of creating a successful warp engine wouldn't just fucking stop hundreds of thousands of km short of the intended goal and then use less exotic means to get to the final location.

I don't even think you can make Warp drive real, but listening to these dipshits with PhDs go, "Uh, achshually you'd destroy the planet by flying into it."

No you wouldn't, retard. You would naturally navigate close to the planet, not into it.

HOLY FAUCI THE WAITING HAS FINALLY DRIVEN SFG INSANE

>>15221854
I don't think astrophysics can realy be treated like that. The real innovation in small missions is usually the concept, most of the time it's coming up with a simple mission which fulls some interesting scientific niche. Occasionally it is applying a totally new technology to do so. The problem is you cannot write down a metric to judge all concepts. You can specify a specific instrument, like an infrared telescope with sensitivity X, band-pass Y and so on. But that is already assuming one particularly concept, and so there is little scope to really innovate.

And I think if the Lunar X prize has shown anything it's that you get what you pay for. Astrophysics missions cannot really be commercialised. You can apply the knowledge to commercial payloads, but this is essentially already done.

>>15221887
The idea is that the warp bubble would scoop up a fuckload of mass-energy on the front edge from collisions with solar wind, interstellar medium, etc. and then release it all as gamma rays when the drive was deactivated on arrival.

>Misaligned Dracos On last dragon to fly
>Combustion in engine bay on last Starlink flight
>CoPV problems
Bros... the FRR was a mess

>>15221894
That's assuming non-existent knowledge about how warp fields might work. Maybe the energy would continuously leak in all directions as the thing is moving, or maybe it wouldn't pile up at all.
All that they've done is invent a very crude toy model and loosely described some of its properties which may have no bearing on how things actually would work, if they could work.

>>15221796
NPC

>>15221892
The problem isn't astrophysics, the problem is the scale/speed/framework in which companies make the product that sells space telescopes.

Lunar X prize was from nearly 2 decades ago before the rise of the commercial industry. It helped some commercial entities, but its not enough. You need NASA to allocate $1B budget yearly to these small scale development of moonshots. Imagine if NASA would fund $100 million cost of your project to send on Starship. $20 million for ride on Starship, $80 million for your Telescope. You're telling me a group of college students cant make a telescope for $20 million?

>>15221899
>You're telling me a group of college students cant make a telescope for $20 million?
If we're talking about a telescope which has the potential to significantly advance some aspect of astronomy, then no, I don't. All telescopes are not born equal. If you want to advance the state of the art then you have to do something new. Without any knowledge of fabricating space optics you would have to buy from existing companies, in which case the economics aren't going to change significantly.

>>15221906
The existence companies dont want to lower the price. Because they wont lower the price, you're saying we shouldn't incentivize other players to make cheaper alternatives?

What sort of fucked up reasoning is that?
>Boeing good because they're expensive, therefore its impossible for SpaceX to make reusable rocket

Each is a new venture. Where they became masters afterward.

>>15221895
What FRR?

>>15221922
Not him, but I can tell you are new to this whole hobby. People were calling Elon a retard for thinking he could reuse rockets. People were saying he was stupid for trying to land boosters. People were saying that it wouldn't matter if they did land them because it would cost too much and take too to refurbish them, like the SRBs. People were saying that even if they did refurbish them no one would use them because they were used and no one would want to risk their hardware on a booster with potentially compromised equipment. People were saying a lot of shit for literal years, and as each gradual step was taken by SpaceX, each small success added to the pile, they finally reached a tipping point and got to where they are now. Because it wasn't just fucking retards like us saying it couldn't happen, it was astronauts, it was NASA, it was Ariane, it was US Senators, it was Ruscosmos, it was literally everyone who had any kind of power or insight into the field whether it be political, technological, or scientific doubting the entire fucking time.

>>15221932
Who is Tom Mueller? Again, not college students.

>>15221945
Alright, but nothing would stop someone who wanted to do SpaceX but for telescopes from repeating that process. It's just will and money.

>>15221945
Guy who worked at a aeronaspace company but whose ideas didnt make it to any of the company products, frustrated at the prospect, he simply chose to make hobby rocket engines on his own time/dime, whereby then became SpaceX employee and became the lead rocket engine guy.

Whats next? They are Americans with bit of money, therefore no college student can do it? Or that they're cis white male and priviledged?

Crying wont get you to space.

>>15221945
I imagine that you would have found similarly autistic space faggots in all weird corners of the burgeoning private spaceflight sector. Like there would probably have been a Mueller equivalent at Armadillo or something. Had history turned out differently they would be household names (among the community)

russian commie uber paranoid state tradition. Changs even copy internal passport system from the USSR. In both cases anything space related was super-duper state secret to mask the stupidity, inefficient waste and outright corruption festering under it.

Hell, even in semi transparent anomalies like the burger system just look at SLS to see another example of how bad of investor the bureaucratic state really is. Apollo only happened because of national pride aligning as well as pushing all the obstacles aside. As soon as the pressure went away Apollo was scrapped for the carpet bagged to hell shuttle retardation and when that went away had to beg others to get up.

>>15221977
No. Shit is going into the drink.

>>15221947
But also the nature of the market is very different. In building launch vehicles you have long production runs, for telescopes they are largely built individually or in small batches. The production line efficiencies that SpaceX employed don't really work. Perhaps it could be applied to spacecraft buses, but many smaller missions already use commercial options.

>>15221954
>>15221966
My point was that he, and others, have a lot of experience. Which was missing in your hypothetical question.

>>15221985
Everyone will have varying levels of experience. College is a testing ground where experience melds such that group of individuals with high levels of experience/knowledge can come together to form clubs and make their hobby into dreams. Its one step away from adult business world. Thats the perfect place to place your bets and grow them into success stories.

>>15221858
>what is it that we don't yet know about the universe
exoplanets? Like at best the knowledge is limited if they even exist or not right now. How about mapping out their surface in detail allowing to get a good look at them. That alone is hundred of millions of foreign worlds just in the near vicinity

>>15221099

>>15221997
Wait, it's even better. They achieved 1 meter resolution. That is really impressive, they also can use it for detecting asteroids.
https://youtu.be/aHBrk065LCQ

Does anyone know if the radar's power affects resolution? How far can you go?

>>15221106
>>15221089
There's also the fact that modern CCDs are much, much more sensitive than film and early detectors. They're also much bigger in terms of pixels. A lot of very beautiful imaging is done with modest refractors with a good CCD.

>>15222045
Planetary radar like this isn't really useful for discoveing asteroids, if that's what you mean. You have to know quite accurately where they are are to begin with. And the range is very limited because the returned power drops of with distance to the 4th power. For most Arecibo runs it seems the distance less than 0.1 Astronomical Units, typically much less. It seems the resolution depends on the sampling frequency, so yes it will depend on the transmitter power.

>>15222093
While its not good for discovering asteroids, it is good for nailing down their orbits accurately

>, im not going to even go into the twisted dream of collectivisim
Soviet space program was less collectivist than the American one. Major organizations organized around individual designers who had far more discretion and decision-making power than in the US, more, fiercer, and pettier competition between design bureaus, more mad-dash scrambling for power, ferocious personal rivalries and ego-collisions, greater autonomy for pursuing research and projects independent of govt. specifications/proposals, less high-level coordination and cohesion, and so on. V.P. Glushko, Chief Designer of Engines, did not participate in the N-1 project because Korolev (correctly) refused to use the hypergolic engines that Glushko favored. The task was then given to Kuznetsov's design bureau. The head of Rocketdyne (or any other company) wouldn't have dared refuse Apollo contracts over propellant choice/engine architecture. Relations between Glushko and Korolev were so bad that Khrushchev brought them and their wives to his dacha in a failed attempt to fix relations between them. One similarly can't imagine the President of the United States knowing the top figures at contractors, let alone directly interceding in their personal matters.

I wonder how the collective psyche of sfg will change after the first starship launch, especially if it at least gets to orbit (I think there is a very good chance of that given the extra year they've spent on engine development, although I think successful reentry is likely).

>>15222249
Chinkshit, my nigga.

Just posting this here in case people haven't seen it:
https://spacenews.com/spacex-proceeding-with-starship-orbital-launch-attempt-after-static-fire/
>Once SpaceX performs that orbital launch demonstration, Henry said the company is ready to move ahead rapidly with operational Starship launches. “We very, very quickly converge on a system that we can operationalize,” he said, starting with launches of second-generation Starlink satellites. “We have a few that are waiting very patiently to be launched on Starship.”
>Those initial Starlink launches will serve as a test program, he explained, refining the launch and recovery of the two stages of Starship. “Somewhere in that journey that will be happening this year, we’re going to make a major pivot to the next piece of the Human Landing System architecture,” he said, by demonstrating the orbital depot needed for on-orbit refueling of the lunar lander version of Starship.
>That will provide additional experience testing Starship through the tankers that will fly to deliver propellant to the depot. “The nice thing about tankers is that they’ve got to reenter as well,” he said. “We’ve created this rubric, in the next year or two, where we will be able to do a lot of experimentation on that thermal protection system that will allow successful reentry of Starship.”
>Starship, Henry argued later in the panel, will sharply drive down launch costs. “We are on the cusp of seeing an opportunity of mass to orbit go from $2,000 a kilogram to $200 a kilogram,” he said. In the long term, costs could further decline to the point where the propellant is the largest factor in the per-launch marginal cost.
“If Elon gets his way,” he said, “you’re at $20 per kilogram.”

Sounds like SpaceX intends to price starship pretty cheaply relatively soon.

>>15222801
$200 / kg is base case, that means someone weighing 80kg would have to pay $16K for a ride on Starship across the globe.

Thats cheaper than a 7 hour flight on a private jet.

>>15222804
Supersonic passenger travel obliterates the E2E passenger business case for Starship, just accept it

>>15222804
Also $20M if its 100Ton, $30M if its 150Ton to orbit. Roughly speaking. Medium launchers are gonna get raped. Anything (non-gov/non-absolutely not spacex entities) above $20M launcher will get mogged. There's no way to justify paying $40M for a 5 ton to orbit vs Starship being able to carry 5Ton to orbit for $30M-$20M, for any orbital body with extreme margins.

>>15222801
[X]

>>15222804
By the time SpaceX is even thinking of Point2Point (very late 2020s at earliest), the launch cost will likely be reduced enough that the per kg cost is closer to $20.

>>15222816
Its ok Doomer, you will be added to the archive for me to laugh at when SpaceX prevails over the doubters like they did in the 2010s once again.

>>15222814
Cant land or fly over cities due to noise, chud. Ain't going no where with that noise. Plus it takes HOURS to get anywhere on jets. Where as Starship could do round the earth in 30 mins.

>>15222804
Earth to earth is not happening.

>>15222824
tbf its not like starship is noise free, 30 mins to anywhere with low launch and landing site footprint is pretty nice tho

>>15222814

>QueSST
>quiet supersonic design
>FAA rescinds the overland restriction
>if not still can go supersonic over sea
>major airlines already signing up
>ignores the hours it takes to reach an offshore platform far from any busy populated place
>ignores the added time just to reach the Starship and disembark which is still far from any airport

Meanwhile the supersonic flight might not be 30 minutes to destination but to reach the airport, board, fly, land, depart will probably take hours less than with Starship E2E

>>15222829
Its noise free when the landing pad is ~10-20 miles away from city.

Can you even fly from Florida to Australia directly on a supersonic jet? You can't. It would take ~12+ hours atleast. So Starship could really corner a market for instant 1 hour cargo delivery service anywhere in the world. People pay quite a lot for Amazon 2 day delivery service. Imagine 1 hour delivery service.

>>15222836
might be pretty nice for military logistics too, very hard to shoot down a rocket compared to cargo planes, would need literal icbm defenses

>Critically, natural hydrogen may be not only clean, but also renewable. It takes millions of years for buried and compressed organic deposits to turn into oil and gas. By contrast, natural hydrogen is always being made afresh, when underground water reacts with iron minerals at elevated temperatures and pressures. In the decade since boreholes began to tap hydrogen in Mali, flows have not diminished, says Prinzhofer, who has consulted on the project. “Hydrogen appears, almost everywhere, as a renewable source of energy, not a fossil one,” he says.

Holy shit this feels straight out of left field, never even heard of this before today, not even all the geothermal stuff mentioned this

>>15222936
Cope, this has been known for decades. Oil and gas companies would have been all over it if they thought it could turn a profit.

We need to radically depopulate the world and move everyone to areas with abundant hydropower like Norway or the Alps

>>15221323
>>15221407

Well that and just raw physical distance. If a Chinese colony on the moon decided to break away, the timeline for armed intersection by Chinese authorities to quell the rebellion is 1.5 days minimum on chemical rockets if they're burning hard, 3 days if they're cruising to the Moon. A lot can happen in three days; and the Moon is spitting distance. Mars on the other hand is 3 months ballistic trajectory minimum during the transfer windows; 6 months OUTSIDE of it.

If a Chinese colony on Mars rebelled, by the time China can mount an adequate launch force projected to quell the rebellion, and it arriving into orbit, then descending down to the surface and make inroads into the colony itself, you're looking at anywhere from 8 months to a full year.

There's no chance China is able to force project to stop the splintering of its colonies that break away and become free states beyond lunar orbit. No amount of creative bureaucracy is going to be able to overrule the simple laws of physics and astrodynamics.

>>15222981
reminder that Neanderthals left Africa long before us

>>15222970
That's only if China gets surprised Pikachu'ed by the idea of their colony rebelling in the first place. What's more likely is that China would have armed state security officers on site from day one. The USSR would not have established permanent large-scale bases on the Moon or Mars without the KGB being present to keep everyone in line. A ship might be able to go rouge and defect after their political officer accidentally slips and breaks their neck, but it'd be extremely hard to pull off something like that with something as large as a colony.

>>15222953
>THE OIL AND GAS industry has punctured Earth with millions of wells. How could it have overlooked hydrogen for so long? One reason is that hydrogen is scarce in the sedimentary rocks that yield oil and gas, such as organic-rich shales or mudstones. When compacted and heated, the carbon molecules in those rocks consume any available hydrogen and form longer chain hydrocarbons. Any hydrogen the oil encounters as it migrates to a porous “reservoir” rock such as a sandstone tends to react to form more hydrocarbons. Hydrogen can also react with oxygen in rocks to form water or combine with carbon dioxide to form “abiotic” methane. Microbes gobble it up to make yet more methane.

>And so, historically, when well loggers cataloged their borehole emanations, they rarely bothered to measure for hydrogen. “The bottom line—they weren’t really looking for hydrogen,” says Geoffrey Ellis, an organic geochemist at USGS. “We weren’t looking in the right places with the right tools.”

Feels like theres a name for this type of fallacy/argument but it escapes me right now

>it's not there because they would have found it
>they weren't looking for it
>because they believed it wouldn't be there
>so its useless because they would have found it by now

>>15222989
the us did it even with british troops present, you also need to take into account that the chinese wont be the only ones setting up shop most likely. you may get a similar effect to what the brits had to deal with when they tried to set up spanish style colonies in the sparesly populated north america where colonists would "go native" and go live with the native americans to get away from the draconian colony system they established at first

>>15222994

>>15222969
>areas with abundant hydropower
Yes, everyone outside of Quebec and Norway should die

>>15222994
Yes I already read the article and the part where it states there isn't a real reserve of natural hydrogen and it's being produced when water reacts with iron minerals at high temperatures and pressure, production is likely inherently limited by this.
