Is it just me or are the grain silos quickly starting to look a lot higher quality

>>12069692
No they have improved over time and aren't as crumbly and wavy as before

Black holes having tidal forces indicates that their mass is not evenly distributed inside, yes?

>>12069708
Your Nobel prize is in the mail

>>12069692
Yes, the human welding has been getting better, and if the recent shipment of industrial armatures is anything to go by, soon machines will be doing the welding and the quality will be dramatically higher. I believe this is one of the primary reasons for the construction of high bays, so that Starships can be stacked and machine-welded in a relatively climate controlled environment. While the vehicle itself is going to be storm-resistant, industrial armatures are still probably best put to work indoors.
Personally in the long run I hope they figure out a way to make stir welding work for Starship, the result would be extremely even and resillient with practically invisible seams between segments. At least according to NASA stir welding is extremely time consuming and requires tens of millions of dollars of clamps and equipment, but when the fuck were they good at designing rockets in the last 50 years?
If they say stir welding is "hard and expensive" I just assume that means "we're too lazy to figure out a better way and somebody with more ambition could solve it in a few months of testing."

Dunno if that’s sarcastic or not. I’d always heard that there’s some magical singularity in the middle or that there’s no inside at all

No fucking way they’re going to fit 100 people in this thing, it’d be unbearable after a week

>>12069765
Imagine the smell

>>12069765
Induce comas, stack 'em like firewood in the cargo hold, easy peasy.

>>12069765
Yeah, I could see it being used as a mass transit ship for 100 people if they're going to the Moon, but some napkin-back math indicated to me that it would be untennable for a Starship to have enough food or life support equipment for the transit to Mars carrying a hundred passengers. Plus the cramping issue would be even worse than pre-industrial ocean travel, at least with old sailing ships if you were getting cramped bellowdecks you could get out and take some fresh air.
I think 20-25 max is reasonable for a Mars shot.

>>12069765
Never say never.

>>12069765
>you'll never have a space orgy with Elon and all of the literal 10's he somehow pulls on the way to Mars
Life is suffering

>>12069765
Wouldn't it be more compact to just send a bunch of women who can have children on Mars instead? As in, more than 50% of the seats are for women of fertile age. Mars colonization should be approached as if we wanted to rebuild Earth after a cataclysm, so basically child rearing is the most important skill a person can have.

>>12069822
>send first crew
>they double in number quickly
Better keep a spare Starship or two on the surface as lifeboats for emergency return trips.

>>12069809
He will most likely need to return to Earth once or twice so they will have to be 18's for a while.

>>12069822
Bone development of children on mars would be catastrophically fucked due to the lower gravity, nobody is talking about this

>>12069835
Artificial gravity my nigga

>>12069809
>pull
Hello, fellow Bong.

>>12069835
That claim is actually an enormous stretch considering simple resistance band exercise has (finally) been demonstrated to almost complete mitigate bone and muscle degeneration even in null-g.

>>12069822
>have to spend several decades raising and teaching them
>have to deal with social issues of "indoctrination" or "what if they don't want to live on mars"

But who would be in the other levels? Booinger, hoopper and amazooner maybe?

>>12069822
The problem is not sending enough people, the problem is sending/producing enough water/oxygen/food/hardware to keep the people alive.

>>12069857
Oh ya? They tested this on new borns retard?

>>12069917
If your newborn can't lift it doesn't deserve to live on Mars.

>>12069917
>All the evidence indicates that even in microgee minimal resistence exercise can almost completely eliminate permanent bone and muscle atrophy or injury as a result of microgee.
>Uh hurrr have you uh, durrr, shot live humans to Mars yet and spent twenty years performing double blind twin studies?
No, fuck you, you fucking dumb brainlet, your inferrence that there will be severe complications from prolonged living in 1/3rd g is simply not substantitated by what data does exist, which indicates that even prolonged living in null g isn't as detrimental as it was originally thought to be.
>>12069920
Based.

Did I miss the hop

>>12069765
Here is the schematic on how everyone will fit

>>12069926
You are actually retarded, the conversation is on the effects of newborns growing up in Mars gravity. Studies on full grown adults in earth orbit don't fucking matter at all that conversation. They are completely different environments with completely different bodies.

>>12069765
Imagine suffocating in that cramped space with a 100 other people when the life support inevitably fails.

>>12069940
Imagine the smell.

>>12069928
>wasting so much space
We need a more modern solution

>>12069937
Even if we assume that your conjecture for which you have provided zero evidence is true, why is it a requirement that children be born on the surface of Mars, as opposed to say, a spin station in Mars orbit creating a simulated 1g environment?

>>12069946
>You could fit the entire nation of Israel in a single starship that way.

>>12069940
Rockets are a scam anyway, they can only work in the athmosphere because in space they don't have anything to push against.

>>12069952
If only.

>>12069949
Its not and Im not saying we should or should not do anything. I fully support blasting 100s of people to Mars and just winging it, fuck ethics committees. Im just saying comparing adults in orbit to new borns on Mars is completely retarded.

Sojourner is cute. CUTE!

>>12070127
Nah i'm working on a hybrid cargo/passenger plane martian ssto,currently i'm testing what's the most efficient way to land,and since for some reason kerbals can't climb back into the pod after leaving it i wanted to bring it closer to the ground by landing like a plane. Unfortunately level flight on mars is kinda difficult,though i was flying at like 7 km asl. Is there any good stretch of land on mars that's flat and low altitude?

>>12070251
The rover that sparked my interest in space as a kid, before that it was just "wow neat shuttle launch what else is on TV".

>>12070213
I was always thinking about the MER rovers. I was too young for Sojourner, but I made a presentation in school back then and I despise Big Bang Theory to this day because they made some bullshit episode about getting Opportunity stuck over a bullshit relationship, ignoring the delay and being retarded over it in general. I looked them up in quarter annual intervals over years and I sure as hell gave a fuck and sometimes lying in bed at night, some 6 wheeled rc car pushing it way past design life gave me more hope than I ever god from a lot of other things, including the holy spaghetti monster of choice and the government.

>>12070256
>Is there any good stretch of land on mars that's flat and low altitude?
Valles Marineris? Or maybe one of the outflow channels?

>>12070245
No offense mate, but I never liked Curiosity, the dimensions, the name, the selfie memes... the time. And the fact that it doesn't run on solar pannels. You can't even cuddle with it properly with that radiation and how big it is!

>>12070273
Guess i can try it out,thanks. Does mechjeb have a landing assist where it lets you mark a point on the navball and shows you how to get there?

hop when :) ?

>>12070295
It's not for landing normally but if I want to keep track of a spot on the ground I just use the rover guidance and waypoint-setting.

>>12070294
Edit , that being said, I kinda look forward to Perseverance for some reason. Must be the chopper and the 2nd go at the wheels.

Hop when?

>>12070295
No clue, I use spent landers or rovers for marking waypoints.

>>12070328
Too windy today

>>12070337
Yeah, 30mph winds now, they cancelled hops yesterday at 26, so you can forget about anything today.

>>12070315
shouldn't we attempt to make a 6 legged rover that moves like a scarab instead of more wheeled ones?
tech for doing so has advanced much in the last years

>>12070357
power requirements too high and too many moving parts for a dusty place like mars maybe?

>>12070182
SpaceX likely don't have the same QA issues that plagued the N1. Nor does SpaceX have internal bickering over which fuel to use and one of the chief engineers refusing to let Elon use his engines.

>>12070182
N1 engines were never tested on the ground and they were cheaply made by communist labour. Raptor engines are digitally designed, 3D PROONTed and tested before being installed.

Good thing it was a boilerplate test vehicle with over a year of engine and vehicle development since then, eh?

>>12070080
Older versions of x-plane (up to 9 I think) let you switch to Mars, flying there was fucked up in multiple ways (taking off and landing in particular), but possible. It even had a bit of actual terrain and a couple of planes designed for martian atmosphere. Too bad most of the development goes into eyecandy now.

>>12070431
It really tells you the story that the engine mounted on SN6 is Raptor SN29, with 2 previous iterations seeing flight at all.

>>12070541
>oh boy! I can't wait to see the first launch of a full stack starship! shame that NASA can't into space.

>>12070520
They didn't try to catch them this time, but did fish them from the ocean.

>>12070548
Anon, SpaceX would be in a hard spot if they didn't get gobernment NASA contracts.

>>12070558
The ISS will still need resupply.

>but Biden will defund that too!
No, he won't. He can't, because international partners would have a massive fit over that. It would be easier to just keep funding the station.

>but Biden would reduce funding so that only one American provider is allowed!
And that would most likely be SpaceX given their low cost and good performance.

>>12070189
Seriously though. Fucking armchair NASA fans, who can’t even name the order of the planets, would get that quote tattoo’d on their arm. And what’s worse is they probably had no idea that rover even existed the week before it’s “muh final words!” message went viral

>>12070518
>>It really tells you the story that the engine mounted on SN6 is Raptor SN29, with 2 previous iterations seeing flight at all.
>This baby looks hard to tame.
Something that's qualitatively obscured further by any parts recycling that goes on between serial numbers; it's hard to tell how many engines they've consumed in testing.

At the same time, its revealing just how advanced iterative development is getting in industrial technology to allow them to churn out so many engines during a test program, which is also of benefit to their processes because they're going to need to build a very large number of engines for each Starship and Superheavy that flies.

>>12070577
IF the ISS continues, and it's mostly US founded.

>>12070581
That's true.
But it's telling you how much of a complex thing this engine is.
If it was a dumb rocket engine being thrown out the window every flight, it would just work.
But this thing has to throttle.

>>12070577
Biden is all about cronyism. He's probably got some cousin in ULA.

>>12070593
Yeah, Has SpaceX done any campaign donation? because they should.

>>12070592
Throttle isn't super novel except as a complexity multiplier. The real difficulty seems to be the very high pump pressures the engine needs to have at the fuel pump, but particularly the LOX pump, to run the combustion chamber at such a high pressure.

>>12070127
Terminal velocity WITH a parachute on Mars is ~200 m/s.

>>12070604
Well, we can't know for sure, but deep throttling isn't really wanted when designing a rocket engine.
I bet you it's like a 3 or 4th derivative equation to get there.

>>12070592
Throttling isn't the hard part, the hard part is achieving everything the engine needs to achieve WITHOUT making the engine impossible to manufacture.

>>12070610
Oh right forgot anon wasn't talking about Duna there. Never fucked around with RSS.

>>12070618
Let's take Merlin as a counter-exemple.
Pintle engine. Literally asking for throttle.
Literally set it and forget it.
In raptor, I have to imagine, it's like rate of change matters. And then you're most likely limited in what you can do next without fucking up the cycle. And the way you made the change is also to be taken into account.

>>12070498
May I introduce you to the compotition?

>>12070632
Thank, now my flight got cancelled because a 777-Max almost crashed because pajeet programming.
Still there a month too late.

>>12070558
Not for long, with Starlink on the way

>>12070754
Are you sure Starlink will be a good investment?
I guess Finance likes it, but, come on.

>>12070762
Good internet anywhere on the world just for $50/mo? Sounds like a good investment to me.

>>12070772
Except people that can spend 50$ a month are already where it costs that much.

>>12070762
700,000 people signed up for the private beta, they won't have any shortage of customers or revenue.

>>12070762
>Are you sure Starlink will be a good investment?
Considering it's the first satellite network of its kind to market, and it can buy launches at-cost from SpaceX, yeah. Amazon's Kuiper may have some inherent advantages due to their connection to AWS, but they don't have any hardware on orbit at the moment.

>>12070777
How does it work? do you have to deploy an antena in your background?(if you have one) Or do you have to spend a Trillion dollars on prototype phones?

>>12070780
Well, they never into Space properly.
Still nothing on New Glen test flight.
This is looking like it's just afailure of an engine.

>>12070777
700.000x50$ equals 35 millions a month.
Like. A falcon 9 a month.
Absolutely nothing and it's still a high price.

when are the hop back up dates

>>12070776
And the people who aren't in those areas? Or would want faster internet for the same price?

>>12070796
They can't pay?
They're more worried about existing than posting on 4chin?

>>12070807
I meant people in rural areas or on ships. There are also high frequency traders who are looking to shave off milliseconds in their communications delay. Not to mention interest from the US military who would like a world-wide communication system with multiple redundant systems, and fast replacement times.

SpaceX isn't some small startup with no idea of the scope of their intended market. They are an established company with talent and brains behind their operations. If they didn't think that Starlink would work, then they wouldn't be investing in it.

New dates for SN6 hop. Sept 3rd-8th.

>>12070893
>Well, you niggamericans couldn't figure out fiber optics, so maybe you're right.
Fiber optics have been figured out and are being used in parts of the country. However, it is not used much in cities both due to the cost of having to dig up lines under busy streets, and government enforced monopolies not wanting to be upended.

>And we didn't need no SpaceX.
Their majority holding of the global launch market says otherwise.

>>12069765
You can fit physically fit in 100 people, capsule hotel style with enough food for a year and life support (optimistically with minimal backup as well)
Problem will be heat.
You would probably need another starship worth of radiators and solar panels.
Also, radiation shielding would be pretty much non-existent.

>>12070890
Generally speaking, would a propellant depot make any sense at all? You'd still have to replenish it and instead of shooting it up ahead of time can just send fuel up if needed. That just adds an unnecessary rendezvous for everybody every time. Now with rockets becoming more reliable and some nations not even caring about weather it sounds completely pointless.

It would be the equivalent of a warehouse on the ocean and there's an entire logistic mentality around not using warehouses called "just in time".

>>12070925
Most spacecraft are propellant by mass, so being able to launch a larger partially fueled spacecraft to refuel in space using a preexisting launcher rather than a smaller fully fueled spacecraft already brings benefits to what can be done in space. There's also the case of reusable "pure space" spacecraft such as landers or tugs. They need a source of propellant to tap into to continue their operation.

>It would be the equivalent of a warehouse on the ocean and there's an entire logistic mentality around not using warehouses called "just in time".
You mean like the multitude of islands in the Pacific that the US Navy had just for storing coal to refuel their ships back then?

>>12070927

Yes, look for landing guidance in the mechjeb menu and you can click on the map where you want to go
It is one of the jankier functions though, for best results adjust your inclination manually to go very near the landing site before engaging it and make sure you have a decent TWR, you need at least 1 to avoid slamming into the ground but if it's too high it won't be able to complete the touchdown and just spazz out a few meters above the surface

>You'd still have to replenish
Also
- you'd have to have it in the right orbit, you can't make detours from orbit like taking an exit off of a highway
- you'd have to have the right fucking fuel, hydrolox won't do when you need methalox or kerolox
- you'd have to keep cryogenic fuels cooled
- hydromeme is still a pain in the ass, it wants to escape everything, it weakens metals, and it's a pain to cool down because half of it has to phase change first, which causes it to boil again
The only useful "depot" would be a tanker ship, placed in the right orbit, just before you need it.

Again, exactly like how orbital mechanics won't work. It's just too costly to change orbits unless you start in the right direction, or have a favorable orbit change at an apo/peri transfer point.

>It's just too costly to change orbits unless you start in the right direction, or have a favorable orbit change at an apo/peri transfer point.
Then have the depots in the right direction. Space may be three dimensional, but optimal transfer windows pretty much narrows things down to something closer to two or even one dimensional. Plus, cutting down the needed propellant mass in a given spacecraft by ~300% by allowing for a refuel halfway through a given mission (such as a resupply craft coming from LEO to the moon, and then back) is a huge bonus for spacecraft design.

>inb4 but then you still need to send a ship to refuel the depot
Which simplifies the logistics needed for other ships. However, the need for refueling ships for depots becomes less needed once ISRU is used.

>>12071150
What problem? It's a nuclear reaction, you're not really igniting anything, you just need to be able to produce a sub-critical mass of uranium plasma/vapor and inject that into the chamber where it gets densified into a critical mass.

Is it good or bad that the amount of engines on SH keeps being downgraded (now from 31 to 28)?

>>12071386
Once the majority of humans in the solar system already live on rotating orbital habitats anyway, it won't even be a big deal to do interstellar colonization anymore, even if we had a maximum per-vehicle delta V budget of just a few hundred thousand meters per second. You could have the equivalent of entire large nations worth of people leaving to colonize another star all at once, and none of them would even be leaving their homes (since the ships and habitats are already their homes). It wouldn't even matter if it took thousands of years to get to another star, and thousands more to get that new colony to the point of being able to launch out its own colonies, in a few million years the entire galaxy would be colonized.

>>12071386
If we could travel at the speed of light, we could colonize the entire galaxy in 50000 years!

>>12071461
Probably a good thing. Elon has already announced the capabilities he wants from SS... so if it can do the same thing with less engines that just means he’s squeezing more juice out of Raptor. I just hope this doesn’t mean he will be redlining each engine for more performance; don’t want an N1 scenario

>>12071362
ESA is going to be fine, but they'll be eating dirt for a while, but i agree that Roscosmos and old space in general are in for some shit

The big advantage over TSTO with boostback burns is that you can have human pilots in both sex dolphins, thus saving you gorillions of dollars in computer hardware and software development if you're pitching this in 1975, and both halves land on runways. Now that Falcon 9 has proven unmanned boostback burns work that's not an advantage anymore, and the sex dolphins have a huge weight penalty from needing to be airplanes as well as rockets.

>(as are all other rockets ever made I guess)
Saturn V is still the best moon rocket and will be until some other rocket sends a bigger than Apollo payload with at least three people on a direct ascent.

>>12071699
Remember Starship is supposed to be same-day reflyable. Once you hit that cadence you can get a hundred flights a month with THREE rockets.

Even if the cost per kg goes way down and Starlink ramps up, I think the demand would fall far short of that capability.

>>12071699
>It would suck if all the Starship hype was for some 80 ton manlet of a super heavy lifter.
Even if it was less than only the 80 tons, a rapidly reuseable heavy lifter with cheap launch costs would sure be great.

>>12071519

What worries me is the complacency from oldspace - it's like they know something we don't.

>>12071728
>What worries me is the complacency from oldspace - it's like they know something we don't.
They know they have their government launch markets by the balls and aren't thinking about how SpaceX can undercut them on price and make it up on volume as decreasing costs encourage more people to launch things.

>>12071728
>it's like they know something we don't
what could this be anon

>>12071699
good thing SpaceX isn't waiting for commercial payloads, and will use it to launch hundreds of starlink satellites instead

>>12071741
I believe that their final goal is tens of thousands of sats up at any given time, all of which need to be replaced every five years.

Once they start to rake in the initial Starlink bux, they'll have a self sustaining Starship economy and all the test flights they could ever ask for.

>>12071728
>The only other explanation is that they are so utterly retarded that they actually believe their own bullshit arguments about SpaceX
Never underestimate delusion and denial.
They'll take any perceived or actual advantages they have over Spacex, no matter how insignificant, and use them as an excuse to continue business as usual. By the time they run out of those, it'll be too late.

>>12071699
starship will reach 150 tons payload capacity, mark my words

>>12071728
I think it’s different for every organization.
•Roscosmos is too stubborn to stray away from the Soyuz design (plus all the money they spent on R&D for ANYTHING else is now locked behind other countries because the Soviet Union collapsed and their rockets became property of other nations such as Ukraine).
•China has smart scientists but absolutely abysmal materials science... even if they wanted to do methalox I don’t think they could, so they are stuck with hypergolics.
•ESA is too divided and rely on the French for anything useful; and as they say: the french don’t copy anyone but nobody copied the french.
JAXA, ehh, they have a few rockets but they mainly rely on other people
•”Oldspace” USA Contractors have gone DECADES getting used to unlimited budgets. Companies like Lockheed and Boeing get an infinite wallet to develop ICBM’s... which eventually get turned into rockets. ULA was a forced conglomerate from the government and they just gave them old rocket schematics like Delta to keep building. And they started designing Vulcan before starship was even on the table
•As for NASA, they pumped too much money into Shuttle and after it ended they needed to keep contractors employed so they built SLS. They kind of had to do this because if they didn’t keep those contracts flowing Congress wouldn’t have given them any money

What large scale operations in space could actually be feasible with current and near future technology that would actually make money and not just be a sinkhole for government subsidies?
>space based power
>asteroid mining
>planetary mining
>gas giant mining (upper atmosphere scooping)

Hard vacuum semiconductor manufacturing, microgravity crystallography and fiber optic cable manufacturing, Starlink, space resorts with spin gravity, passenger service to said resorts, lunar ice mining, and that's all just in Earth orbit.

did we get full audio of musk's mars speech today? did he drop any new info?

>>12072080
Good.

>>12072127

The Starship program costs 5 billion? That's more than I figured.

>>12072184
that's not too bad considering what it's trying to do

>Russia exits from CIS Lunar Gateway.
Dumb move but not unexpected. Russia was in a unique position where they could be a part of both China and NASA's Moon missions. Or maybe it wasn't dumb and they were forced to choose? I know Russia had to submit to the Artemis Accords to join NASA's program, but nobody knows what terms the Chinese offered.

>>12072184
Waste of money, SLS can do it for cheaper and it's proven

>>12072206
Anatoly mentioned that it was a barter agreement between China and Russia, so I guess he explains the deal behind his paywall? China had to offer some good deals to get Russia to pull out of an all but guaranteed Moon base.

>Spend 5 billion on 2 SLS
>First one blows up
>2nd one is fixed and refurbished, costing another 2 years and 1.5 billion

What do we think /sfg/?

so when starship is operational it wouldn't get scrubbed by wind like it was for SN6's hop attempt right? i thought starship being chonky lets it fly in most conditions, something that's necessary for frequent flights

>>12072230
wind really fucks super long and thin rockets, starship will fare much better

>>12072230
I think spaceX is being extra careful so another prototype doesn't explode or crash

>>12072230
the hops are empty beer cans, anon
full beer cans will be much more resistant to wind

As long as government handouts are a thing (they always will be) unfortunately they will be around until the heat death of the universe
