janny
you know what to do

don't bump this thread or the wrath of god will fall upon us
just let it die

>>15886295
owari da

whya re there too threds up?

>>15886307
me and someone else both staged at almost exactly the same time, just don't bump this thread

>>15886324
put "sage" in the options field, it lets you post without bumping

THIS IS SO WEIRD AND CONFUSING.

>>15886330
don't tell me how to sage dummy, i did it in the post you replied to

1 trillion hours work here

>>15886388
was it for you or for the other mouthbreathers still using this thread

>>15886389
8/10

>>15886394
well he replied to me so i thought he was trying to tell me, even though the post i had made that he replied to was already saged.

>>15886403
since when did they allow it to work on image posts btw, I don't think it did back uh pre 2010 or whatever

stop bumping this thread.

>>15886411
idk honestly
also DAMNIT CIRNO FUMO STOP MAKING ME BREATHE MANUALLY

>>15886432
you were the first post to bump the thread in like half an hour dude, everybody else has been using sage

>>15886442
youre bullshitting. dont. test. me.

>>15886470
oh my god,
see i fucking told you some retard like this was gonna show up and do this

>>15886388
sage goes in all fields

>>15886484

if you just don't respond to him he will be unable to post organically and resort to spam, which is reportable

>>15886389
I think my art is improving

>>15886523
its not too bad, did you draw the crawler?

>>15886531
your post inspired me

>>15886566
this one was slightly disappointing but I think I managed to communicate my artistic vision.

>>15886609
so does he have a rope attached to his neck, which is attached to the space shuttle?

>>15886629
yes, that's the idea.
I wanted it to be attached to his foot, but it just wasn't working out.

>>15886630
it's good anon, people get the idea i think

>>15886632
thank you, I'm already working on the next one.

>>15886630
wont he die though?

>>15886815
hes thunderf00t

>>15886849
carry on

So why is NASA bothering with above ground structures for the Moon and Mars?

>>15886928

>>15886928
>>15886940
Above ground structures need less initial work. Even then, a lot of theoretical mars habitats use regolith for rad shielding, which makes them already kind of underground. Nice pictures, btw.

/sfg/ should have underground threads like this one. It's actually more comfortable here than on the other thread.

>>15887521
this is why I didn't want to make a general back in 2018, I knew it was a mistake

>>15886523
Could the crawler go faster if it were nuclear powered

>>15888387
yes? probably. I think keeping it quite slow is a good idea, but not as slow as it is. In any case, the main problem with the crawler is the grift and pork that's tacked onto it (eg. alabama river rocks), which has the side effect of making it barely functional. I think I remember reading about this thing constantly breaking down.

>>15886609
You can just put him in the shuttle if you him to die you know?

>>15888504
certainly a weird way to stage innit? have people posted two new threads at nearly the same time before?

>>15888513
yes, not that rare but it makes continuity a bit worse

>>15888513
IDK, but stages have been reused before.
I remember it being a bit unpopular.

SpaceX normalized reusing stages.

What martians serve durina First Landing day feast?

>>15888521
world's first re-usable thread

>>15888530
caviar? I mean, if they have a lot of fish farms they might be able to make it work.

>>15888452
This amuses me about China and Russia. They look at the USA and SpaceX and Starlink and say to their people "I WANT THAT, I WANT A MEGACONSTELLATION" when they fundamentally can't afford to with their choice of economic and political circumstance. It's like that scene in iron man where Obadiah yells at the gay scientist. ELON MUSK WAS ABLE TO BUILD THIS IN REDMOND WASHINGTON, WITH A BUNCH OF LIBTARDS

>>15888540
it's funny because megaconstellations like these only fundamentally make sense when you actually have the launch price and cadence to make it viable. china might just make it if they were to use all their different rocket factories but nobody else has the potential ability to sling a similar sized network into orbit.

>>15888540
it's true, real life is exactly the same as capeslop, and my hero, Elon Musk, is iron man

that of course makes tim dodd, the everyday aestronaut, spiderman

>>15888540
Yeah all the articles about "The future Chinese Century" and how Africa/India/South America will magically line go up and meet and eclipse neoliberal western economies because number on graph are delusional. Its a funny myth that got accidentally spread by stupid western economists who just applied a bunch of intangibles from their own societies to developing ones. If the west shits itself completely in decadent decline and dysfunction the developing world just stops developing. I think that enough smart people have worked at SpaceX, embraced its approach, that even if SpaceX explodes at some point eventually a new company would pick up the torch but obviously the fastest way would be their continued success.

SpaceX lost a fairing half. These fuckers are amateurs and an embarassment to the whole industry. Shameful shit.

>>15888550
china is already launching satellites for their megaconstellations. its still early though. they launched 3 of them the other day.

>>15888560
wish we had detailed stats on fairings. people track the boosters... haven't seen the same for them.

>>15888550
It would cost China a fortune, but it wouldnt kill them. Something similar killed the Soviet Union, at least in part, so it is absurd for Russia to be pushing it. but they proclaim lots of delusional paper projects so meh

>>15888566
wow, 3!

>>15888555
This but unironically

>>15888569
so? spacex only launched a handful of starlinks early on.

>>15888567
What the are you planning to do with that information? Feel happy about yourself? jerkoff

>>15888596
I just want to see how many times they've reused a fairing is all.

>>15888602
you would already have this data in full if you were subscribed to L2.

>>15888608
Hey what’s the continental US doing up there? Get back down silly!

>>15888608
what would happen if the continental US was put on the luanr surface for 30 minutes and then returned to earth?

>>15888618
it would be extremely painful, for you, big guy

>>15888608
This

>>15888608
the south pole really can be divided up into large territories for many countries

>>15888625
not really, the area of interest is the size of rhode island

>>15888618
for 30 minutes definitely everyone would die, but I wonder what the max time would be to keep everyone alive... we could probably survive one minute

>>15888632
ok now do 30 seconds

>>15888625
not according to the artemis accords

>>15888625
If China infringes on our Lunar territory that is a declaration of war and nuclear weapons can and probably should be used on their Earth territory in retaliation

>>15888638
I think enough heat and atmosphere would stick around for <1 minute to keep most people alive. Although we'd probably shed enough atmosphere that it causes an insane pressure imbalance when we get back.

>>15888530
Nothing but The Emperor's Finest.

>>15888642
lets just assume the only difference is the pure vacuum and when we get back everything is normal again

soon

>>15888648
That's not how rocket engines work and it pisses me off every time I see it.

>>15888648
i think those chinkonauts would die from sandblasting before the guns

Partial automation is probably not too difficult to work out.

>>15888632
You'd lose pressure immediately and then the nitrogen in the blood gases out. I doubt 10 seconds are survivable.
Probably some people in deep bunkers or mines would make it. And scuba divers, since the water can buffer the pressure drop a bit.

In Star Wars Episode 8, The Last Jedi, General Leia goes into space for a long time and survives

https://twitter.com/elonmusk/status/1728890535736484255

>>15888722
you wouldn't lose pressure "immediately". The moon still has gravity and the atmosphere wouldn't be stripped out entirely at once. It'd go fast, but humans can survive well below 1 bar.

>>15888618
There would be much rejoicing.

Space race 2.0: why Europe is joining the new dash to the moon
---
https://www.theguardian.com/science/2023/nov/26/europe-moon-space-race-esa-india-russia-china-japan
>The European Space Agency’s plan to build a cargo vessel that can convert to a crew ship is one giant step in its ambitions to compete with rival lunar exploration programmes
> By the unanimous agreement of the 22 European countries that fund and govern Esa, which include the UK, the space agency would open a competition for industry to propose a cargo spacecraft to fly to and from the International Space Station (ISS) by 2028. But the gamechanger came in what Aschbacher said next: “We will also conceive it in a way that it is not a dead end, meaning that it’s open and can evolve in the future to become a crew vehicle if member states decide to do so.”
> The impetus for Esa to urgently chart its own direction towards a human transportation system came in February, when the agency published a report called Revolution Space: Europe’s Mission for Space Exploration. Authored by a 12-strong team of independent advisers, the document argues that space is undergoing a revolution comparable with the growth of the internet 20 years ago, and that, like the internet, this will affect all domains of life. In many ways, it already has.
> Interest in going to the moon is exploding around the world. Dr Nasr Al-Sahhaf experiences this on an almost daily basis. He chairs International Moon Day, which is observed every 20 July, after being sanctioned by the UN general assembly in December 2021. Sahhaf’s job is to interface with companies and governments across the world that have an interest in celebrating the future of lunar exploration.
> “I found that there is not only global interest in humanity’s going back to the moon, but also there is this clear zest to explore and settle the moon as if to make up for such a long absence since the Apollo missions,” says Sahhaf.

>>15888851
> The downside of this global interest, Crawford worries, is that it could result in some kind of new space race and lunar landgrab unless some form of coordination and eventually governance is agreed upon for activities on the lunar surface. Yet there is a marked lack of legally enforceable agreements.
> Ultimately, whatever international organisation evolves to govern lunar activities, whoever gets there in the first tranche of countries will inevitably be the ones with the greatest say in outer space activities. And that means there is more on the table than just the moon. Many see the moon as a proving ground for the big prize: Mars.
> “I think it is essential for Europe that when humanity decides to go to Mars that Europe is part of that and we have a seat at the table,” says De Winne. “That will only happen if in Europe we have the necessary capabilities.”

>>15888857
How is that a downside? Competition breeds innovation.

>>15888860
we shouldnt compete though because its bad.

>>15888837
Here are some Marvel analogies for you, which might be more your speed

>>15888851
ESA would not be able to launch astronauts before 2030

Thinking about buying this for my daughter who's going to be born in January

>>15888866
its nover. they are never flying again. They lost their CO2 lisence

>>15888866
Never.

>>15888740
The entire air column would expand and decompress immediately due to the lower gravity. You'd probably get something like 0.2bar after a few seconds. Humans could survive that for a bit if you lower the pressure slowly, but if it happens fast, you get decompression sickness, like scuba divers ascending too fast. The solubility of the gases in the blood changes and the dissolved nitrogen boils off and forms bubbles in the blood vessels.

Where is it, Melon?

>>15888908
where's dragon XL too

>>15888740
Yes you'd lose t immediately, air pressure on Earth comes from the air's weight alone. It weighs less on the Moon, so it would instantly "jump" and expand until the pressure at the surface fell well below 1/6th of one bar.

However even if you only teleported America and everything in it, with no air brought along, 30 seconds in hard vacuum won't kill you. It'd just badly injure you.

>>15888908
>>15888929
Easy to build, not worth focusing on

>>15888932
if everyone on the continent was injured badly simultaneously, a lot of people would there
there would be nobody to take care of you and assuming the medical staff was magically uninjured, there would not be enough people to take care of everyone

>>15888929
Gateway is still years away from launch so there's no need to hurry.

>>15888929
Its kind of strange why they got a contract for dragonxl. whats it's purpose if Starship will be available? I guess it can be sent in one launch instead of 14?

>>15888929
probably cancelled

>>15888947
No shit. Didn't say otherwise.

>>15888530
It'll be like Thanksgiving in the US, so focused around what the first colonists could grow most quickly before running out of canned Earth food. That probably means yeasts (beer?), mushrooms, fruit and vegetables that can grow well indoors, and freshwater catfish (tilapia and catfish have similar requirements but tilapia doesn't taste as good).

>>15888556
The myth spread because the economic extrapolation fed perfectly into Maoist theory about the inevitable rise of thirdies and so the shit-libs of the world doubled down on it for twenty years. China failing to complete the Belt and Road will be to Maoist theory what the fall of the Berlin Wall was to classical Marxism, a permanent discrediting. Then we just need to handle the watermelon-green and sexual-politics bullshit and Marx will finally be gone as a force in Western politics.

>>15888955
IIRC they got the contract as a company, not for a specific vehicle, and so "Dragon XL" was more politically viable than "Starship resupply lolololol" before Starship had flown.

>>15888977
>China failing to complete the Belt and Road
How did they fail?

Ooh boy, Mars Sample Return drama is getting fuel on the fire. First, there was this interview
https://www.planetary.org/planetary-radio/spe-what-went-wrong-with-msr

And now we have reaction reaction. Space policy nerds get your hockey sticks
https://caseyhandmer.wordpress.com/2023/11/26/what-is-going-on-with-mars-sample-return/

>As a dubious public service, I humbly offer my translation and light editorializing to help inform less catastrophic space geeks what is happening with MSR. The usual disclaimers apply! I no longer work at, and do not speak for, JPL. I represent only my own opinions. Previously, my opinions on this topic were so obscure, so controversial, and so retrograde that I could barely hint at them in public for fear that the message would be lost.
>But last week, a remarkable interview occurred on Planetary Radio between Casey Dreier – Planetary Science Space Policy director and Orlando Figueroa, the industry veteran who chaired the Mars Sample Return Independent Review Board. The transcript is apparently AI-generated and may have occasional errors. In this interview, the quiet part was said out loud to a surprising degree, creating space for useful commentary. In this post, I provide that commentary on the relevant parts of the interview below in italics.

Get in fags, we're trashing JPL.

>>15888995
NASA is just reaping what they sow.

>>15888995
Can I get a quick rundown? I don't have the patience to read either of those links.

>>15888995
>In particular, we have always known that MSR was going to be extremely technically challenging, but for some unspecified reason a bunch of extra, optional complexity was added.
Why does this continually happen? No stupid schizo theories about congressmen having manipulation super powers

>>15889009
Those sample returns are never coming home. It's a dead end...and NASA is starting to realize that. Heads are gonna roll.

>I’ve seen many suggestions of privatizing [Mars Sample Return], putting it out to bid, or just dropping a $5b prize for anyone who can bring back the samples. I don’t think this can work. There are a handful of corporations in the US that could actually execute MSR: Lockheed, Boeing (maybe), JPL, and SpaceX. Lockheed and Boeing will not do anything fixed price, especially something so difficult with such an ornery customer for so little money. SpaceX doesn’t need the money anymore so they will take the money if it’s on their path already, but then the sample return lander will be a Starship – a one size fits all hammer that makes everything else look like a nail. Starship, incidentally, can ship a ~100T ERV in its cargo compartment, meaning it can bring back more than a tonne of rocks, which would be awesome! And JPL will say that they can do MSR for $5b but they won’t spend their own money on it in advance, and they don’t like to share with others.

Would you be embarrassed if China recovered Martian samples before the United States?

>>15889014
>SpaceX could do it
>but then the sample return lander will be a Starship – a one size fits all hammer that makes everything else look like a nail
Why is this said like it's a bad thing?

Why is SpaceX dicking around with the construction works at LC-39A? Without a second launch site they won't be able to perform any Lunar mission in a reasonable timeline.
I'm reminding you that they can't launch more than 5 time a year from Starbase.

>>15889021
Expect it to ramp up now that the water deluge plate is proven and they won't have to backtrack on it.

>>15889020
Because thousands of people would have to admit they are frauds who stole money for decades. They wouldn't care that much at the end of the day but it would bruise egos.

>>15889017
Marginally, yes. However I think it could ultimately be for the best since it will remind Congress that using every mission as a slush fund and jobs project has tangible consequences. Better the wake up call happen early.

>>15889020
Because it would invalidate the work of thousands of people at jpl. The MSR vehicle needs to be a bespoke single use rocket with a unique delivery system and a seperate one of a kind rover mission to transport the samples to the rocket.

>>15889025
I guess the plan it to manufacture the whole steel plate, dig arount OLM, install it and then finally place the table. That could be 6 months away.

>>15889020
Because you're schizophrenic.

>>15888908
another muskian lie

>>15888538
The only "people" who like caviar are Russians because it tastes like cum. For obvious reasons.

>>15889020
Because the point of MSR is to shovel money into JPL for more design work. If there's another thing that can do it (let alone better), then it's a threat to JPL's revenue.

>>15888618
Global tsunamis as the oceans rush to fill in the CONTUS hole and are then displaced again

Last bits from Casey:
>There is no law of physics that says that Casey and Jack need to be old men by the time MSR succeeds, if it succeeds. NASA’s behavior reflects its incentives. If you want to understand what the incentives are, look at the behavior of the organization. Asking for more than a billion dollars a year indefinitely on a mission with fundamental unaddressed architectural issues that doesn’t even report to the senior layers of management? How did that happen? JPL’s entire business line (exquisitely expensive complex space robots every decade or so) is threatened by Starship, and the response absolutely needs to be a concerted organizational focus, including re-orgs where necessary, around increasing production rate, development rate, and customer value. Not trying to squeeze the last few drops out of the outdated business model. The insane thing is that nearly every program and project manager within JPL understands and recognizes this, and a good number have left for SpaceX, Blue Origin, or other companies. It’s not for a lack of intelligence or will that this process innovation is unable to occur. There’s something deeply rotten in the core of the organizational structure that, like all bureaucracies, serves to protect and defend the bureaucracy and process over all else.
... something deeply rotten in the core of the organizational structure
Reminds me of Feynman's conclusion.

>>15889062
>JPL’s entire business line (exquisitely expensive complex space robots every decade or so) is threatened by Starship
how? deep space robotic exploration is no less complex just because it's suddenly cheaper to get your robots on the right trajectory

>>15889056
They have no lack of work in designing actually useful test article drones for Mars and Moon colonization but I guess admitting private space will colonize soon psychologically admits defeat.

>>15889020
Because they still don't get it

>>15889017
Be hilarious if the chinks stole the samples.

>>15888932
why would it not decompress in a wave traveling at the speed of sound

>>15889062
>reminds me of Feynman's conclusion
Could you please elaborate? Did he say something about spaceflight or a more general subject?

>>15889020
its a threat to JPLs existence like red dragon would have been
a threat to their "business model" in the very least, the money spigot would stop

>>15888932
>30 seconds of hard vacuum won't kill you
Instant change from 1 atmosphere to no atmosphere would kill you instantly. Rapid decompression is far more catastrophic to your body than simple exposure. Your blood would boil, degas instantly and all the fats and such would precipitate out too, you'd be the embodiment of an American with fat in their veins. Your digestive tract and respiratory system would either collapse in on themselves or violently empty themselves, depending on if the air inside didn't come with them or if it did

>>15889072
One look at a JPL rover should tell you that the fucking thing is absolutely not a multi billion dollar machine.

>>15889072
Starship would not only get them on the trajectory, it would be the lander as well and eliminate a large portion of the rube goldberg machines JPL is using to land mass on the surface of mars right now
and you are also completely wrong about them not being less complex
yes, they would be less complex, you can exchange more mass for less complexity
mass autism means you have to over-engineer the robotic probe making it much more complex

>>15889086
I would guess it refers to some comment about shuttle accident investigations and NASAs bureucracy in general, but I don't know/remember the exact quote

>>15889098
on some parts of Mars maybe, but there's a 0% chance starship is landing on Io or Venus or an asteroid or whatever. For basically every mission not immediately made redundant by SpaceX's Mars plans, it's just an LV.

>>15889101
Starship would float in Venus' atmosphere

>>15888989
Most of the projects are incomplete or abandoned.

>>15889093
it wouldn't be instant
there's a wave

>Feynman's conclusion

https://history.nasa.gov/rogersrep/v2appf.htm
>Official management, on the other hand, claims to believe the probability of failure is a thousand times less. One reason for this may be an attempt to assure the government of NASA perfection and success in order to ensure the supply of funds. The other may be that they sincerely believed it to be true, demonstrating an almost incredible lack of communication between themselves and their working engineers.
>Let us make recommendations to ensure that NASA officials deal in a world of reality in understanding technological weaknesses and imperfections well enough to be actively trying to eliminate them.

Data from Kepler reveals reason behind shrinking exoplanets
--
https://www.nasaspaceflight.com/2023/11/shrinking-subneptunes/
> Interestingly, among the 5,000+ exoplanets that have been discovered and cataloged by NASA, ESA, and other agencies, there is a strange absence of exoplanets whose sizes are between 1.5 and two times the size of Earth (between super-Earths and sub-Neptunes). In a new study using data from NASA’s now-retired Kepler Space Telescope, scientists may have found evidence for why this size gap exists — the cores of the exoplanets are pushing away their atmospheres from the inside out.
> Scientists believe that the sub-Neptune exoplanets are the possible cause of the size gap, as previous studies have shown that sub-Neptunes are susceptible to atmospheric loss. The exoplanets can lose their atmospheres if they don’t have enough mass, and therefore enough gravitational force, to keep their atmospheres. If this theory of atmospheric loss is true and the sub-Neptunes don’t have enough mass to hold on to their atmospheres, they’d likely shrink to the size of super-Earths, explaining the size gap between super-Earths and sub-Neptunes.
> Christiansen et al.’s results allowed the team to conclude that photoevaporation could not have occurred within Praesepe and Hyades, as there would be very few exoplanets with atmospheres within the star clusters if photoevaporation had occurred. This means that core-powered mass loss is the leading theory behind atmospheric loss in sub-Neptunes.

I know you're shitposting, but with hindsight, it would've been foolish to actually pursue Falcon 1's development further once they had the resupply contract for the ISS with Falcon 9.

>>15889224
Yeah I'm just shitposting. I'm trying to track down the magazine in which I first heard of Elon Musk and SpaceX but I can't seem to find it. I thought it was Popular Science or Scientific American but I can't find it in either of those. From what I recall the article profiled several private rocket companies and had a big image of Elon Musk and talked about his plans. Nothing I've found so far matches my memory though.

how can water be extracted on Mars in large enough quantities for fuel generation? I understand there is permafrost but I don't understand how it can be used without human labour

it was correct when it was written (unless the writer fucked up), which is part of the point. just weird to see how much his stature has changed

Inevitably this will require robotic fleets numbering in the thousands of regolith harvesting/ processing/ transporting units for even small permanent settlements. We're still a long, long way from this being feasible. First step is Starship being able to finally put 1000's of tons of hardware down on the surface

>Less than a month until Vulcan attempts to fly

>>15889276
Each Starship puts what, 150 tons into LEO? Assuming they can each land 150 tons on the Martian surface as well, which seems dubious, that's 7 Starships to Mars just for the first thousand tons. And those Starships will be stranded there at least until propellant production can begin, if not scrapped on the spot. Reusability requires Martian infrastructure that will be very expensive to create without reusability already in place.

We need indigenous people to populate Mars. The historical pattern of White colonization and displacement of the natives requires it. We simply don't have sufficient precedent for colonizing uninhabited territory. It's why Antarctica and the oceans are still uncolonized.

It seems obvious to develop Starship variants that would land on Mars and act as on-site fuel production plants that are never meant to leave. Separate Starships would act as temporary habitats and laboratories until larger habs could be constructed with inflatables from Earth. The first few decades would be spent getting water collection going followed by mining and eventually basic manufacturing. This is all technically possible, it's just a question of whether or not we will ever see enough launches in our lives to even begin the process

>>15889308
As I see it, packing a methane production plant into a starship makes sense but dropping a bunch of robotic bulldozers onto Mars to start permafrost harvesting would be a significant challenge. Starship has a propellant capacity of a 1.2 thousand tons, so they'll need to process several thousand tons of Martian soil and permafrost at least. The logistics of this seems daunting, particularly if it's meant to be done using robots (no humans around to service them...)

How large a rocket would be needed to bring 1 ton of payload from Mars surface to LMO with current thrust figures for hypergolics? Flying out multiple stages and keeping one in orbit for the transfer back to LEO is probably more efficient than a full Mars surface to LEO or Earth surface, even.

It's actually kind of funny I'm reading this now. Suddenly a shocking amount of NASA decisions since the 2000s make sense as they try to get away from JPL
APL getting more work running missions, Other lower tier (and vastly cheaper) universities getting development jobs, private firms like kinetX and SwRI doing stuff only NASA (Ames, KSC, GSFC) used to do before. Psyche was the straw that broke them though: JPL had gone from merely extremely expensive to an actual risk, and that's when NASA's immune system went into overdrive. They may have had differences with JPL before but as soon as risk enters the picture NASA has an allergic reaction. MSR blowing the budget in an environment where JWST was finally in the rear view mirror must have pissed off everyone from the OIG to the national academy (which --specifically-- called out MSR as a budget risk on the decadal survey long before anything was public)

if what you say is true then its actually bad. it massively complicates settlement. humans will have to live on a dry patch.

>>15889791
Humans live on permafrost all the time here on Earth.

>>15889792
permafrost is scarcely settled, especially when the permafrost is under a thin layer of topsoil. don't even get me started on mining.
the reason is that your settlement, or whatever youre doing, will produce enough heat to disturb the integrity of the permafrost. that would be especially true for an underground Mars settlement. it seems like mining through kilometers of that would be a nightmare which makes resource extraction nearly impossible.

>>15889791
It's only true in some areas.

>>15889806
You're forgetting that the permafrost IS the resource for Sabatier synthesis of methalox. They can structure the settlement like an open quarry.

> Work to develop full-flow staged-combustion-cycle methane-liquid oxygen rocket engines producing 200 tons of thrust includes progress on overall design and components.
> Clusters of 26 of the reusable engines will power the first stage of China’s Long March 9 super heavy-lift launcher, according to designs presented earlier by officials from the China Aerospace Science and Technology Corp. (CASC), China’s main space contractor. CASC is understood to be targeting 2033 for a first test flight on the massive rocket.
> The paper notes research began in China in the 1980s and that 10-ton and 80-ton-thrust methalox engines have now been developed. The latter have undergone successful hot fire tests and mark advancements in engine reliability and reusability.
> The paper states that core indicators make the engine comparable to the SpaceX Raptor engine that powers Super Heavy/Starship. As the world’s second full-flow staged-combustion-cycle methalox engine it is superior to Blue Origin’s BE-4 and other domestic and international methane engines, the paper claims. The latter engines have a higher thrust, however.

This mission will help get on-orbit capabilities in the hands of U.S. warfighters faster. The Firefly team is concurrently ramping up for Alpha FLTA005 for NASA. Get more details on our upcoming missions here: fireflyspace.com/missions/

All that will come after they prove they can launch them successfully, there's no point testing stuff that might not even be on the production version.

>Thermal regulation
That's because it undergoes 90 min cycles of day/night. In a high orbit it can be in sunlight 100% of the time, and bbq roll to stay the same temperature.

when will NASA (re)learn that there will ALWAYS be unexpected complications when sending shit out to space? spend billions on a single shot and expect the consequences.

Vehicles and buildings on Mars will be painted cyan or bright green for contrast
much like they are painted orange or red in the Arctic

>>15890341
it's OVER

congrats to them on their falcon 5 equivalent test article i guess

oh no! not my heckin -0.5 microns!

If nooglin reaches orbit before Starship, I think I'll have to kill myself

>>15890342
wen hop

>>15890349
this thing is not lasting 20+ years as hyped in the slightest with those mirror distortions
if one is already out of alignment and post-correction error is already sliding up, before motors start to wear down, post-capture corrections to ghosting aren't gonna save it
there are rocks in space. dont think you can escape them.

>>15890350
it doesnt matter. starship will probably get to orbit mutiple times next year, then dozens the year after.

>>15890362
cope.

I haven't read it yet, but have listened to a podcast with the 2 authors. I found the host, Adam Conover, insufferable- a smug, ignorant fool. He kvetched about the poor astronomers not being able to see stars anymore due to megaconstellations, and kessler syndrome. I fully expected to hear him to bring up the FWS talking points like 'muh beetles, sharks, ocelots, sharks, whales' but thankfully he didn't.
The book sounds intersting, and I like SMBC for the economics content, but like most science-related comics such as xkcd, they go full retard when dealing with certain topics.

Never trust an astronomer, they're all liars. This is why we need to go to space and see things for ourselves.

>>15890368
astronomers: nooooooo you cant just go there you will contaminate it and ruin the natural beauty

>>15889478
rape.

>>15890071
Could be an option if you want to have an excuse to leave a whole Superheavy in orbit to be picked up later for making a big station.

I cant cope with how stinky elon is.

>>15890400
ok I'm sorry I didn't know.
really too bad though

These people are fucking delusional. Shitting on capitalism, commercial spaceflight, starlink, all while doing a video call OVER STARLINK. AND THEN SUGGESTING LAYING PIPE AND FIBER OPTIC IS CHEAPER LMFAO WHAT THE FUCK

>>15889020
Because it invalidates the sample return anyways
Why go through the trouble of picking up random packaged samples when you could harvest a few tons of rocks on the landing site instead

if spacex builds too many starlink satellites we might run out of precious metals. all the satellites will deorbit and turn to dust, then all of it is lost. eventually we will be all out of ore, and we just turned it to dust

Those comics are all the same. The punchline is always some brown science woman being pointlessly pedantic and yelling.

It's fine. The surface quality was better than required or expected, and the changes to scheduling mean that it will likely still be in spec in 20 years. Note that it wouldn't cease to be useful even if it was degraded that far.

>>15890324
>don-d-don't worry, it's just one mirror, there's no rocks out here
Nobody ever said that. Impacts were expected, and the mirrors and sunshield were tested for it. The impact rate now matches expectation.

>>15890446
I picked up a cool rock in my back yard and one at the park and some sand from walmart's parking lot.
it's good to have such a diverse range of environments in my mineral collection.

>>15890344
Who cares, Starship will launch one 20 times bigger before it breaks completely.

>>15890472
JPL completely fucking shit their pants from this post

Wait a minute...why can't Jewish people just stay home and mind their business? Why are they trying to stop me from going to Mars?

>>15890367
>You Don't Actually Want to Live on Mars
Are they saying it as some sort of a revelation? I don't think that anyone thinks that life on Mars will be better than on Earth. People want to do this not because it's easy (it's not easy at all), but because it's something that has to be done for the future of Mankind.
