I'm actually really interested in seeing an official mock-up of the Natty Team lander. I wonder what the layout is gonna be like. Lord knows we won't get anything official for a long time though, we don't even have official SpaceX Moonship diagrams or renders.

>>15751166

Putin and Kim meeting at Vostochny is kind of a big deal.

Best Korea gaining access to Russian spaceports and/or modern rockets in return for providing Russia with munitions is a huge step up for them.

So they did another cryo test on Booster 10

>>15751184
so is βest Korea a filter, or is board culture really just that strong around using the phrase?

No, I'm not going to type the regular name, on the off chance that it is filtered because I never get filtered by anything (except Bαseduz)

so this is why their relationship is bitter

>>15751102
I better note this in case anyone wants me in on their startup. Also there's some irony here, Elon Musk isn't a founder of Tesla yet he has founder status. And them Mueller is a SpaceX founder but Elon cut him out.

>wanting welldwellers to go colonize the worlds of the solar system so your orbital societies can enter in some "mutually beneficial" trade relations and eventually result in total orbital victory as all large objects end up being mined down into nothing to fuel the geometric growth of that society of orbitals
real shit?

Normalize orbital bombardment of bureaucrats

>>15750963
It is perfectly natural to want to drag Mimas over to Mars and progressively disassemble it in order to give Mars new oceans plus a healthy bump in surface elements required for life (particularly phosphorus)

>>15751266

Can you even conceptualize the order of magnitude of energy required?

>>15751202
why do glowies send new agents here without even briefing them first?

>>15751259
A viable interstellar drive will obviate the need and most of the desire to disassemble all planetary objects. The majority of the solar system will be preserved for sentimental reasons, with the exception of the larger asteroids.
System-scale projects will happen, of course, but around stars with lifeless and/or boring planets.

>>15751288
>also a group of engineers left SpaceX/Blue Origin to form Stoke Space
I think this is the case for most space startups in the last decade

>>15751279
Apply enough time and distance and sentimentality stops being a factor.
Consider your attitude towards the ethiopian rift valley. Would you care at all if someone turned the ethiopian rift valley into an industrial complex, solar farm, pumped storage reservoir, or even a typical large city? How about blasting the peak off of one of those hawaiian mountains to build a big ass telescope?
Why would the vast majority humanity, while 2/3rds of the way through colonizing the galaxy, care whatsoever about Earth? Most people probably wouldn't even learn about Earth in school beyond a single unit in elementary classes.

Why is it so mediocre?

>>15751272
Large number of large spacecraft powered by large fusion engines dragging large chunks of Mimas to Mars orbit then cycling back, repeatedly, for a long time, and other incredible tales

>>15751311
Hey proton, do a backflip

>>15751288
>Not a fan of these rocky moons
Mimas has a surface made almost completely of ice. It only looks like that because it never differentiated and never resurfaced itself after impact events.

>>15751352
Sensors are hard to install correctly when you're drunk, please understand

>>15751256
No irony at all. Mueller didn't put in a monetary stake. Musk practically single-handedly funded Tesla.

>>15751360
>>15751352

>>15751350
Starship went the other direction and managed to do it MORE than once in the same flight

>>15751360
However it is much harder to install upside down, no matter BAC.

>>15751365
yeah, one of Teslas other cofounders was already independently rich (had like 200mil or somethign) from another startup but was unwilling to put almost any money into it

>>15751305
It has some really strange ideas to appeal to investors, like a hanging upper stage and a double walled upper stage encapsulation. They'll eventually go TSTO with a deployable fairing once development is far enough along that investors can't pull out after seeing it's just a late Falcon 9.

>>15751360
wasn't the problem actually bad design? the sensor had to be installed by blind feel after assembly.

>>15751288

>hydrolox

So you'd have no problem with either of the things I mentioned, and find the more recent and more closely personally tied historical artefacts more important to you, thus proving my point.

>>15751202
what?
no it's just a meme to call the impoverished ultra totalitarian shithole of north korea best korea because we're different on this website

>>15751395

>>15751395
Hydrolox upper stage but methalox first stage with FFSC engines as an afterthought. I like the idea of an aerospike reusable upper stage but can't trust Stoke.

>>15751375
yeah I wonder if all that meme stuff is just to appear unique or something, perhaps easier to sell to investors than simply saying "we are making a falcon 9 clone"

>methane
Why did no one in the cold war figure out this magical substance

>>15751413
what does it even have on kerolox?

https://www.youtube.com/watch?v=0srs5jZ1qdg

>>15751415
supposedly it makes it easier to do reusable rockets since there's less coking (carbon deposits) but it doesn't really have much on kerosene

>>15751415
no coking (or less coking) of the rocket engines so easier to reuse, much easier to ISRU on Mars
there might be something else too

>>15751413
the 20th century was full of scientists who all wanted to be Einstein and find the simple, elegant principles underneath the universe, so they were all focused on using hydrogen and oxygen because of its mathematical elegance. It wasn't really until the 90s that we all got disillusioned and decided that the universe was confusing and ugly and getting stuff to work was the most important part.

>>15751415
no kerosene on Mars

>>15751202

>>15751301
No spins yet
>>15751305
The bar is currently F9 cadence and payload, will soon be F9 cadence and Starship payload, they cant pass either of those bars even when Neutron is finished so it will be mediocre.
>>15751413
Cold War was only briefly about spaceflight idiot
>>15751424

>>15751397
I'd feel the same way about pretty much any significant early archaeological site, as well as prime architectural examples from later periods.
There's not really any tangible evidence of human accomplishment in whatever random valley we crawled out of.

>>15751413
ISRU refueling on Mars wasn't that important for suborbital ballistic missiles

https://www.quora.com/What-are-the-differences-between-kerolox-and-metholox-in-rocket-engines
if the shit in pic related is correct, then in addition to less coking and Mars ISRU, you also have slightly higher theoretical ISP, higher specific energy and its cheaper than RP-1
the negatives are: more difficult to handle due to being cryogenic, lower specific heat capacity, less dense than RP-1
the biggest reason to use methane is probability the reusability aspect if you look at launch on earth and ISRU at Mars (not even sure it is feasible to synthesize RP-1 there, possible I guess but I would imagine it would be much more difficult)

I don't think SpaceX has a 2nd drone ship available to do recoveries at sea.

>The Falcon Heavy's two reusable side boosters for the Psyche mission returned from their previous launch on July 28 with a commercial communications satellite. SpaceX is refurbishing those boosters—each with three flights on their record—for the Psyche launch. The side-mounted rockets will be recovered again at SpaceX's Cape Canaveral landing zones after the Psyche launch, and they'll be reused and expended on the launch of NASA's Europa Clipper mission in October 2024.

>The center core of the Falcon Heavy rocket slated to launch Psyche is also in Florida for final launch preps, as are the two new aeroshells for the rocket's payload fairing. This will be the eighth flight of a Falcon Heavy rocket, but the first Falcon Heavy with a payload heading for another planetary body.

Why no livestream?

> A four-year-old Seattle-area startup called Stoke Space executed a successful up-and-down test of its “Hopper” developmental rocket vehicle today, marking a major milestone in its quest to create a fully reusable launch system.

>Hopper2’s 15-second flight took place at Stoke’s test facility at Grant County International Airport in Moses Lake, Wash. A hydrogen-fueled rocket engine sent the test vehicle up to a height of 30 feet, with a landing 15 feet away from the launch pad, Stoke CEO Andy Lapsa told GeekWire.

>>15751574
Impressive, honestly thought it would most likely fail the hop
>Going forward, Stoke’s team will concentrate more fully on developing its rocket’s first stage and ramping up operations in Florida, Lapsa said.
I'll be curious to see this.
>Why no livestream?
small startup in the desert pls understand

>>15751413
Because it was objectively inferior to what was used in the cold war. It was only with the idea of large and rapid reusability it became attractive. Kerolox was able to reach almost the same ISP while being more dense, more powerful and a lot easier to handle. Hypergolics and solids were a lot better for long term storage and pure power. Hydrolox were so much more efficiant that it made up for it having so little density and more complexity. Methalox meanwhile was not efficiant enough to make up for its lower density and weaker power than Kerolox/hypergolics and not dense enough/powerful enough to make up for it being less efficiant than hydrolox.

Kerolox/hypergolics for the first stage and hydrolox for the second stage is still the GOAT combination for getting as much mass into orbit as possible.

It's not bad for reusable either. Falcon's never had serious problems using RP-1 and a block 6 version with a hydrogen fueled second stage would be an interesting evolution.

>>15751223

Why? Everyone knows he was never a real president.

Joe Biden is the most pro-space president since Donal Trump.

indeed it is. you may be among the few wise /sfg/ posters

>>15751646
i've been saying this forever. what administration did spacex win HLS? here is a quick hint: not under (t)rump

>>15751652
HLS Moonship was selected between administrations, thus bolstering my opinion that minimal government is fucking based

>>15751634
I'm just happy to see North Korea drifting away from China's sphere of influence. Anything that gives Beijing headaches is likely to get a smile out of me.

>>15751652
The HLS contract was LITERALLY given right before Biden's administration could assign the new administrator for NASA retard, because they knew that was the only shot they had at giving it to SpaceX. There was a whole controversy around it.

>>15751658
acting administrator ratman

>>15751652
SpaceX won HLS because it was the only sound proposal.
Never mind the bitching afterwards under the guise of "we need more than one supplier"

>>15751661
That's why they had an emergency second selection process where they could still get a non-spaceX lander kek. Fuckers.

>>15751661
Was it an illegal decision? Could it be argued in court to be illegal?

>>15751666
Sure. Everything the Regime doesn't like is illegal. That's how you define what "illegal" is these days.

Someone's got reading comprehension issues and was too mad about Drumphy's existence to get the joke

>>15751672
>>15751668
yes but that was on BO vs SpaceX sorta grounds. I mean could the administration itself sue NASA saying or some party and argue that an acting nasa administration does not have the power to make that decision. I wonder why BO didnt use that line to sue

>>15751674
>Drumphy
Unnecessary and rude

>>15751677
their whole argument was that the selection was hasty and unusual, but BO's bid was so awful that it didn't hold up

>>15751677
Because it's not illegal for NASA to make decisions without a none temporary administrator. They still had an administrator at the time. It would be the same as saying decisions by NASA under Bridenstine became illegal under the new one.

>>15751681
It is necessary to be rude to you

>>15751688
Happy for them but it’s still a small launch vehicle

>>15751715
1-2 tons and fully reusable will put them in a pretty good place to undercut Rocket Lab and Falcon9 rideshare. There's not going to be a huge market but there's definitely an opportunity for them to carve out a comfortable segment of the market.

The real interesting money is if they can get into returning payloads from orbit. I don't think a hydrogen stage would have great linger times at this size, but they could drop off an orbital factory for Varda and then pick it up and return it later on another flight.

>>15751693

/sfg/ retards see one little hop utilizing the basic laws of physics and think the entire market has been shifted, wow

>>15751889
Yeah, this is barely a step above armadillo aerospace or masten

>>15751882
>made more progress with reusability than Rocket Lab that's been around for over a decade
I don't know if that's a claim you can make. RL's actually recovered and reflown orbital hardware. Stoke's good a good game plan but they've only done one preliminary hop on a second stage testing article. They're not getting anything to the pad before H1 2025 at a minimum and RL is going to be reflying first stages next year.

The market was disrupted by ARCA

>>15751922
I would suspect that Stoke might get to first flight and re-usability before RL does. SpaceX went from Hopper to S20/B7 in 2 years. Stoke's hop is following a similar curve, but their rocket is vastly less complex than Starship. It's basically 1/2 a Neutron, which makes it simpler overall.

Science!

>>15751882
A few seconds of wobbly flight is a long way from a functional reusable second stage, this isn't even to the point of SpaceX's Grashopper flights.

>>15751950

Former Spacexer here. Tom is filthy rich. Just because he didn't buy in immediately doesn't mean that he doesn't have millions upon millions in stock from bonuses and stuff in the early days. He races Porsches as a hobby. He has an insanely nice house. The last few years he worked at Spacex, he was basically just an advisor who came in a couple days a month to make sure people weren't fucking up Merlin.

He doesn't dislike Elon because he got fucked on stocks, he dislikes Elon because Elon is an asshole.

>>15752007
They’re pretty fucking annoying but I give SpaceX a pass because their shit actually works and they’re the best in the business.
The nuspace launch market has an epidemic of too many cringey cutesy ha-ha-so-silly naming schemes for missions and hardware and it’s annoying. The first couple of rocketlab mission names were funny but now it just makes me roll my eyes. And stupid shit like the giant googly eyes on the mission controller’s computer in the Astra control center was so stupid, like don’t do that shut until you actually have a few successes under your belt

what are the next features/upgrades on starship? so far i see three gridfins instead of four, electrical TVC, and raptor 3. what else is in the pipeline?

>>15752056
eTVC is already incorporated starting with booster 9
I don't see why they would go to 3 grid fins, mass ratios on stage 1 don't matter that much and 4 fins gives you redundancy if one fails

stretched starship and an actual payload door that isn't just a fucking three inch wide slot for starlinks
6 R-Vacs on starship
orbital prop transfer/refueling demo - that may happen even before any commercial (non-starlink) payloads are flown

>>15751500
Bigger fairing for Psyche? They were recently boasting about having more fairings than they had room for in storage. Or maybe NASA is so anal about planetary protection that they won't trust anything that isn't factory new.

Interesting that Clipper needs that much more payload, but looking at the C3 needed makes it pretty plain: 82ish vs Psyche's 50 or so

Stokers can borrow other first stages while they make their own
Stokers never lose

Would you be willing to dedicate your life or even lay it down to be a colonist on Mars? The full experience of harsh radiation, isolation, long communication times, probably 12 hour shifts for whatever job you have. This could be when you first get there or slightly after the colony is set up (i.e. a few dozen people), the backbreaking and labor intensive phase. Not 2070 lay back and pump methalox phase.

The thing is, it's not gonna be "hey i wanna go", no, applicants will be carefully screened, everything will be expensive and exclusive for a few lucky ones.

Yeah, that's too expensive even for most middle-class people of the world. And that's already counting mostly just us first worlders. Assuming this thing would even ever be open for others than Burgeristani citizens. Extremely exclusive for a few lucky ones, globally speaking.

> A banker from Lazard recently warned that SpaceX, led by Elon Musk, could be forming a monopoly in the space business. Founder of SpaceFund and Space Frontier Rick Tumlinson, who invests in SpaceX, disagrees. Tumlinson says SpaceX is moving so fast and doing so well that it's "more incumbent on the other companies to catch up, to adapt, and to move forward to compete at the same level as SpaceX." When it comes to rivals, Tumlinson says Rocket Lab (RKLB) is new and advises people to "give them some time," adding that CEO Peter Beck and the company will be "nipping at Elon's heels."

The suit seeks dismissal of a case filed by the Justice Department Aug. 24 alleging that the company’s hiring practices discriminated against asylees and refugees. That case was filed with the Office of the Chief Administrative Hearing Officer (OCAHO) in the Executive Office for Immigration Review, which handles cases related to immigration law.
> SpaceX’s lawsuit is based less on the specific details of the Justice Department’s case and more on its constitutionality.

I mean radiation is a risk, but I don't see the downsides. Isolation is only a factor if the total number of people are <50. If the initial seed colony size is between 100-200 people, that's enough people that it would take you nearly a year to fully meet and know all of them. Another year to build relationships of trust between all of them and you. Mars transfer window opens every 2 years, and the journey from Earth to Mars is 3 months +1 week for landing, unloading, housing, etc. As long as the ships keep coming, every 2 years, 3 months, 1 week, another 1-200 people are going to arrive at your location to bolster your budding population. So the isolation issue basically solves itself. As far as long communication times go, its 7 minutes each way; 14 minutes between each; that's not so bad. Lastly, long communications is probably a good thing, keeps all the doom posting and doom scrolling influencer shit Earth side; keeping the data stream coming to Mars pure.

People are actually getting better, not worse, at responding to and designing against solar electromagnetic interference. The big losers in the Carrington Event were gigantic conducting cables, which are now deliberately grounded at much shorter intervals than at the ends.

NASA and others around the world are now monitoring the sun nonstop for flares and other events that would cause disruption in space hardware. "Safe mode" is now a design requirement for example, and this has saved more than a few missions. If the Starlink satellites actually got fried, which is still technically possible, they are designed to easily be replaced.

I was aware of that, but I'm also wondering what a colossal fuck-you EMP would do to them. I haven't found anything about starlinks being hardened against that sort of thing, but I imagine the idea has come up since it's one of the few actually surmountable EotW scenarios with enough investment into infrastructure

part of what would make a carrington 2: electric boogaloo so deadly is the total communications blackout meaning banking and monetary systems collapse, total logistical failure, and general chaos. If starlinks could actually survive such an event it would be a monumental improvement

>>15753098
yeah, and only a decade ago the STEREO-A solar monitoring satellite caught a CME that was something like 90% as energetic as the estimates for the Carrington Event, but it just so happened that earth wasn't in the path when it went off. when considering how fast the sun spins, that means we missed at least a minor apocalypse by like 8 days.

>>15753154
kerolox also has lower gravimetric energy density, meaning you need more mass of kerosene for the same dV, and higher structural requirements plus internal helium COPVs for pressurization (methane can do autogenous pressurisation, kerosene CANNOT) offset the smaller tanks entirely. At that point all you have is soot problems and worse ISP, for a fuel that costs literally dozens of times more and cannot be ISRU'd

Also, raptor has insanely high chamber pressure which is where most of the super hig h TWR comes from, and historically kerosene engines have been limited to much lower pressure

ok so it can be ISRU'd, but at an extreme increase in complexity and cost for an inferior fuel. Methane is the king of ISP/thrust/density without being a histrionic bitch like hydrogen (leaks, valve issues, deep cryogenicity, boiloff, embrittlement, and diffusing through metal like it isn't even there)
>>15753195
afaik RD-180 has the highest chamber pressure of any flown kerolox engine (could be wrong) and it tops out under 270 bar, which is respectable but nowhere near the 350 that raptor 3.x is already at. In any case kerolox is gas-liquid not gas-gas, which makes higher pressure very difficult

that's all it would take. wouldn't end up being a ton cheaper, but nothing is with nasa. challenger still happens but no one dies. collumbia does not happen at all.

Actual answer: get rid of the SRB reuse. Remove the parachutes to get more payload, it cost more than building them from scratch.
Put foam insulation on the inside of the ET. You'll need less this way, and it won't shed off and fuck up the heat shield.
Add another section to the SRBs for more throost and dV
Only 2 main engines on the orbiter.

>>15753234
how woauld making the srbs liquid make it cheaper?

>>15753303
You know how much shit has to be overbuilt because the SRBs are constructed fully-fueled?

>>15753296
Cant stand Tegmark. Insufferable pseud

>>15753305
I know it's a problem that they were transported in segments and stuck together at the launch site like lego, but I didnt know being constructed fully fuelled was a problem. If its easier to build the srb fully fuelled rather than put the fuel in later, why did they even try to reuse them? seems retarded to me

>>15753226
this thing
basically smart reuse: shittle edition
only the engines in the pod return so the heatshield is much smaller and no wings mean you can have relatively decent payload
you don't risk scattering 7 astronauts over all 50 states each time you want to put a satelite in orbit in the first place
you don't need to completely rework the whole ET manufacturing process and build a new launch pad
methalox would have been better but that would mean designing new engines and ET
>>15753235
the original ET had stringers and was far cheaper to make
SLS is using isomemes to take vertical loads

>>15753206
>afaik RD-180 has the highest chamber pressure of any flown kerolox engine (could be wrong) and it tops out under 270 bar, which is respectable but nowhere near the 350 that raptor 3.x is already at

RD-180 is also early 80s tech, considering Energomash managed to make the RD-701 by the early 90s, which ran at 300 bars on a 2.5:1 Kerozene-LH2 mixture, I'm sure 300 bars could have been reached if development continued.

>>15753314
Why did the shuttle launch with all 7 crew every single time? surely they werent all needed.

>>15753313
they wouldn't need the artisanal river rocks if it weren't for SRBs

>>15753318
Say that again

>>15753317
Because launching with 7 astronauts wasn't more expensive than launching with 2... so why wouldn't they launch with 7? It's basically free ticket

>>15753271
fuck off troon

>>15753314
>SLS is using isomemes to take vertical loads
I’m convinced this is just an excuse. F9 and SS use stringers. They made SLS more expensive and difficult to produce on purpose

unlike everyone else's fantasy ideas this one actually came very close to being picked IRL.
I know it seems terrible but it'd actually be way better than what we got.
>much safer because no tile strikes and it could have a launch abort system.
>it wouldn't be framed as an all-purpose workhouse, therefore it wouldn't kill off all competing launchers, therefore there'd be no "go-fever" resulting in management ignoring glaring SRB issues.
>orbiter wouldn't be married to the rocket, a cheaper replacement launcher could and likely would be perused later on.
>NASA in general wouldn't be married to the rocket, very low chance of any SLS type bullshittery.
>would become operational years sooner, potentially soon enough to save Skylab.
>very little loss in capability.

>>15751715
Should be scalable, and they're doing their first rocket fast & fail tolerant, so I think they'd be able to pull off a big rocket later so long as their small one works.

That's gonna cost you 3 billion, aka more than Crew Dragon dev cost

The engine only functions like an aerospike at high altitude/vacuum. In deep atmosphere it's just a ring of small combustion chambers fed by a single turbopump that exhausts thru the hole in the middle.
It's not an altitude compensating nozzle so much as a bimodal propulsion system: pseudoaerospike for higher Isp on the way to orbit, discreet thruster array for Earth landing and recovery.

> China launches new batch of Yaogan reconnaissance satellites
> HELSINKI — China added to its recent flurry of reconnaissance satellite launches early Sunday, sending three new Yaogan-39 spacecraft into orbit.
> A hypergolic Long March 2D rocket lifted off at 12:13 a.m. Eastern (0413 UTC) Sept. 17, rising into overcast skies above the Xichang Satellite Launch Center in southwest China.
> Four objects from the launch were tracked in roughly circular 495-kilometer-altitude orbits inclined by 35 degrees.
> Yaogan satellites are thought to variously carry optical, synthetic aperture radar (SAR) and other sensors. Some satellites are described generically as being for “electromagnetic environment detection and related technical tests.” This may indicate the satellites are for electronic intelligence gathering.

As time goes on the requirements for what makes an acceptable Mars colonist will go down significantly. Obviously from day 1 you want people who have degrees and practical experience in at least three technical fields, plus preferrably a year or so of submarine time, but by year 30 a typical certified pipe fitter in decent physical shape could make the cut. Personality will be the biggest hurdle for most, especially anyone who has a temper or gets frustrated easily.

An actual good idea, in my sfg?
Prestige will definitely be a significant factor that will draw in many people who otherwise wouldn't be bothered. Some people don't care at all about space but are yet hypercompetent engineers, and love to show off how good of an engineer they are. Those people would likely be able to live in an early Mars base for a decade without losing it or getting burned out.

The problem is achieving a useful thrust to mass ratio in order to accelerate fast enough that you can get the thing outta the Saturnine system without the other surrounding moons drawing it in or interacting gravitationally in any way which could go haywire and crash those moons together (not that it wouldn't be cool as fuck to do that).

The TWR issue requires that you either physically reinforce Mimas somehow so it doesn't just pancake under the gorillion newtons of thrust you need to apply, or much more feasibly, you move it piecemeal, one billion tonne block at a time, using still huge but otherwise feasible tugs.

Or if you mean how to improve the shuttle we actually got then the answer is LRBs.
The SRBs generally took about 3 weeks to stack in the VAB and required the halting of various other tasks throughout the entire building (most importantly: stacking the external tank and the orbiter, even in other VAB cells) and this meant that the maximum possible flight rate was some place in the mid teens.
Introduce liquid boosters (with an assumed stacking time equal to the ET/orbiter) and no other work has be paused, multiple shuttle stacks can be processed simultaneously and the maximum theoretical flight rate shoots up to about 50 per year.
At this point orbiter turnaround is the primary barrier to higher flight rates, order another orbiter or develop shuttle-C and then I think annual ET production becomes the limit.

>>15752329
>Yeah, that's too expensive even for most middle-class people of the world
