But think of all ULA and Boeing employees! If we don't spend 100 billion on space probe its not worth spending our taxpayer money!

>>12011745
NOAA/WHOIfag here, I think NASA still ought to do the expensive probes (though maybe only for trans-martian expeditions and missions to Venus/Mercury or the sun and shit.

I just want to see a rusty old fleet of NASA-owned heavily modified Starships with a rotating stable of old SuperHeavys pushing them into orbit, packed to the gills with crunchy space PhDs with beards and weed vapes to run some Carnegie Mellon/Champaign-Urbana postdoc project to use the custom-built synthetic aperture radar rig to map methane ice deposits on the lunar surface for 2 months.

Thread reminder that ULA lobbysts are sleeping and snorting cocaine with American senators for government money, they received 3x the money of SpaceX while not having reusable rockets, not being able to dock with the ISS and having a really shit cockpit, filled with switches and buttons.

Americans are corrupt.

>>12011756
Before they come back to earth and refit the ship for 3+ months to mount NASAs core sampling drill for a 3 month mission to the lunar surface to drill a 3-mile borehole and core analysis of the lunar crust, while it's sister ship is flying with the synthetic aperture radar interferometer on a LEO mission to map some ocean shit for a joint Stanford/Caltech/UT Austin project.

An Anon from a previous thread gave me the inspiration to create a real family of rockets. From left to right are 10, 20, 50 and 100 ton launchers. The last two are two separate concepts, one, the R-4U uses a LF/O first stage and cryogenic second stage to lift 100 tons, while the other the KLS-U is a single large cryogenic core stage with four LF/O boosters.
The KLS-U is nearly double the R-4U's cost.

The Expanse is really dumb, why would space miners be the poorest of the solar system? You need way more skills than a regular Earth miner.

And in no way would Earth be one single nation.

>>12012067
One world governments makes for easier writing. A cooler premise is if all the nations of the world broke out into two or three factions, competing to be the one world government

>>12012074
what is "1984"?

>>12012004
They need to update the video name and description. It still says July 31.

>>12012067
They're still at the technological stage where space habitats are only theoretically self sustaining. I think this was one of the most implausible handwaves that the setting has to make IMO, with technology sufficient to make the Epstein drive I find it highly unlikely that humans wouldn't already have multiple 100% independent self sustaining colonies, mega-sized space stations across the solar system, and multiple colony ships en-route to at least Proxima Cent.
Also they do have more than one faction on Earth, it's mentioned that the United Arab Emirates is still independent, although at some point over the course of the story it's absorbed into the UN.

>>12012067
Belters probably make more than welfare earthers. It's just that they don't have free air and water and they don't fully profit off their own work because everything is owned by earth and Mars megacorps, including the stations they live on. I love the setting of the expanse when it begins. I wish we could get a story with all of the politics and realistic spaceflight and no protomolecule or wormholes.

>>12012067
Where i live (belgium) there is a shortage of technicians, company's all want them but cant seem to find enough of them.
It's not a education problem, there are enough people who have the skills, it's just that the fucking pay is ridiculously low compared to the work you do for the company.
My mate is a technican at a company that automated packaging lines, he and other techicians, a project manager and a couple of designers do al the work from start to finish, they design it, they make it, they place it, they test it.
And yet at the end of the week some HR bitch or some marketing dick in the same company makes more then them and looks down on them.
We live in a world where a diploma means more then your actuall skills, so yeah i think expanse belters are not far of from reality.

>>12012105
Yeah the optimal mining company would build cities on the Moon/Mars for housing, supply ships and electricity/water, and take most of the profit from the workers but give them enough to thrive

>>12012114
The most realistic part of The Expanse was ice miners refusing to get shafted by gay commie Belters and withholding shipments.

>In January 2004, President Bush announced a new long-range plan for NASA. Bush directed NASA to complete the International Space Station by 2010 and then phase out the shuttle. The ISS would be used as a test facility for long-endurance space missions, while the US sent a series of probes to the Moon in preparation for new lunar missions by 2015 or so. New Moon flights would lead to a lunar base that could be used as a stepping stone to a crewed Mars mission. As details of the plan were nailed down, to support the new vision NASA would develop new space hardware:

>A "Crew Exploration Vehicle (CEV)" in the form of the "Orion" space capsule, along the lines of the old Apollo capsule but with a capacity of six astronauts and, with the proper support modules, capable of extended space missions. The Orion would feature a launch escape system -- the shuttle had proven such a feature was a necessity, not a luxury. A planetary lander named "Altair" was considered for later development.

>An "Ares I" booster to launch the Orion, based on a shuttle SRB with a liquid-fuel upper stage, with a lift capacity of 25 tonnes (27.5 tons) to low Earth orbit (LEO).

>An "Ares V" heavy-lift booster, clearly based on "shuttle-derived booster" concepts, but ultimately mostly a new-design vehicle, with a lift capacity of 160 tonnes (176 tons) to LEO.

>In the Moon landing scenario, an Orion CEV would be launched on an Ares I booster, to rendezvous in Earth orbit with an Altair lander launched by an Ares V booster. The combination spacecraft would then boost out of Earth orbit on a lunar transfer trajectory. After arriving in Moon orbit, the astronauts would descend to the lunar surface in the Altair lander.

Is there any way to prevent deflating the price of heavy metals once we conquer space mining? Like let's say I have a way to process platinum... just as easily as iron or lithium. Do we do what diamond companies do and create an artificial short supply to keep prices up? I feel like leaving a bunch of platinum in a warehouse is asking for pirates to come raid

>>12011833
i always thought sls looked cooler when they were going for the all white paint scheme tbqh

>>12012130
Space piracy is still scifi shit, but I guess so is mining. Once companies start processing and storing stuff Im sure people will begin looting. It might start as workers taking a bar or two for themselves, but pretty soon there will be organized raids if you don’t protect your goods

>>12011681
>>12011684
That's a really high shed they're building there.

>>12012137
Probably can't even lift off with the weight of the paint weighing it down.

>>12012130
>Is there any way to prevent deflating the price of heavy metals once we conquer space mining?
Keep it in orbit and tell the mudfoot scum to lick your solid platinum underwear.

>>12012139
water tower

>>12012143
considering how little sls can actually lift, the loss due to paint weight would have been more than worth it for the A E S T H E T I C

>>12012203
Where's his onions?

>>12012235
I read that this is the worst season to launch from Kourou, rainstorms and high upper level winds are typical.
But I've always wondered, why is it so hard to design a rocket to launch through wind shear? This seems to be a very common reason for launch delay. Have there been notable launch failures due to wind shear?

>>12012217
kek

>>12012257
I think maybe you gotta be a big honkin rocket for it to not be a factor in fuel consumption

>>12012257
The last thing you want when doing a launch is fucking cross wind blowing into your shit.
You have x fuel to get off the ground and into orbit, then offload millions of dollars of payload.
Suddenly comes a gust of heavy wind up there and you spent too much fuel trying to punch through and webm related as your upper stage tries its best in vain to make orbit.

They don't risk it. 9/10 you might be able to push through with enough fuel in the tank. 1/10 your upper stage falls down through the atmosphere and it's RUD fireworks.

it doesn't cost fuel to correct for wind shear
it requires your rocket be strong enough to resist the wind trying to bend it in half

yeah, you could be underneath the rocket

>>12012351
Arguably being strapped to the rocket is worse because your torment would be prolonged, as opposed to instant vapourisation.

SpaceX was streaming on-board views for their Falcon 1 test flights over a decade ago and yuropoors and oldspace still use 90s simulations lol

take a nap, then go on strike

I tested my homemade solid propellant today, and the results were as disappointing as the last one. Some of the propellant appears to not have even burned. I'm not sure what went wrong; I used a more precise scale and measured out the components down to the tenth of a gram, I sealed the motor from moisture after casting, and I even used less binder than industry standard. My only suspicion as to why the reaction isn't getting hotter than it should is a combination of a weak oxidizer along with said oxidizer spending too much time reacting with the binder before it reaches the fuel. Anyone else have any ideas?

This is somewhat disconcerting, as I was planning on moving on to hybrid motors, but since I can't guarantee that a simpler solid propellant motor would work my confidence in making a hybrid work has taken a blow.

>>12012359
I don't know. They did have rocketcams on many of the first launches, and now they replay the same ones for separation events.

No, that's true, but capabilities that completely defy the 4 forces of aerodynamics raise some questions. Is it Ayyys or did someone here learn an entire new paradigm of physics while keeping it hidden? I simply think the latter hypothesis is less likely due to Occam's Razor.

That's not how that works. A case has to be made for deviating from the status quo (keeping footage and testimonial confidential). Pros: none. Cons: potentially handing over actionable intelligence to hostile powers

>hen their technology level should be at a place where an unmanned satellite could gather any and all information they need?
How do you know that?
I'm assuming that they (if they're real), for the most part, work within the current laws of physics. I.E. being closer to something without interference means a faster data rate. But we are ultimately speculating about a psychology that isn't ours.

Wow bezos is working with nuclear propulsion engines right now, it's a bit of a hush hush thing but it seems he wants to bring as much cargo to the moon as he possibly can as fast as he can.

Look it up one of his engineers (still working at blue origin) talks about this on youtube.

Seems like with the boost of capital he will be able to outcompete spacex and nasa and fund his lunar base dream.

welcome to the world of solid propellant
Vega is designed to reuse their existing solid tech from the Ariane 5 boosters for a standalone small launcher. Japan did the same thing with Epsilon.

>>12012657
If they can accelerate to 60-70Gs from a dead stop without generating a monstrous plume of exhaust in the form of vapor, heat, or radiation, and can do so through a significant atmosphere without generating any hypersonic detonation, plasma wake, etc, and can survive such an acceleration and not instantly explode into a cloud of tiny pieces or sublimate into superheated gas, it's magic as far as we human beings are concerned.

>>12012699
Yes, but have you noticed how rapidly technology has snowballed recently? If they have a 200k year head start on us, and assuming those grainy videos actually show what people have interpreted is being shown, that means that there would obviously be things about physics and the nature of reality that we don't even remotely understand. Mechanisms for propulsion, energy generation and materials science so arcane that we would have to assume that most of our fundamental understandings of the universe are only barely accurate enough to be workable.
The ayys would be so far beyond us already that to them we appear only a tiny fraction more advanced than a chimp sticking a stick down a hole to reach some insects.

>>12012770
>If God isn't a perfectly rational being, why the fuck would aliens be?
If they have the means and the will to travel thousands of light years one must assume some degree of intelligence, rationality, and intent. When Europeans first sailed to the New World they didn't just dick about around coastlines before setting off for home. Why would a theoretically advanced alien species do the equivalent here? If you're saying that their motives can never be understood or explained then why even bother having the conversation?

>>12012565

But they did, it's called the moon.

>>12012781

Because Europeans were constrained by a primitive medieval technology level. Dunno about you but drag racing primitive fighter jets and fucking with the world's most advanced military and their equipment sounds hilarious, 10/10 would do whenever I encounter a sentient species.

it's about 9.4-9.6km/s for equatorialish low orbit and polar adds another 0.5-0.8km/s or so, according to my best friend mechjeb

See I don’t get why people sincerely thought that first stage or stage reuse in general was “not economically viable”. At the very least imagine if they threw away the entire shuttle at every launch? Like sure the shuttle sucked but it was cheaper to reuse it than to throw it away. And OldSpace even knew that, and they still shitted on reuse.

ArianeSpace even investigated making reusable boosters for the Ariane 5, and yet they suddenly pivoted when SpaceX announced their reusability plans. Same with Roscosmos.

>>12012892
Source?

>>12012909
There's a quote from some frog from ArianneSpace that basically says making reusable rockets would be bad for the company because then they'd have to cut down on the workforce in rocket manufactory. I imagine that's the man reason why OldSpace companies never seriously considered it

>he says the Ariane Group can't make a reusable rocket because it would be too efficient

>>12012909
Oldspace is expendable and expensive because the sticker price is the old million dollar hammer accounting trick to hide the black aerospace budget. The Shuttle actually did hit its reuse cost targets but the entire black sector depends on Shuttle derived accounting fuckery, which is why "continuity of Shuttle technology" is such a bipartisan selling point. You don't honestly think it takes Aerojet Rocketdyne $165 million to make a single RS-25, do you? Cost plus is another trick to hide these shuffles. Note how actual fuckups like Boing! are treated differently than the usual malarkey.

Seriously doubt ayys are real, ngl. If their spaceships are so advanced as to accelerate faster than any human craft ever built, there would not only be plasma created from the force of friction with the air but also would probably kill anything that's inside the spacecraft, if not destroy the craft itself.
Quite simply, it would be like the Sprint Missile on cocaine. Unless they can develop some technology that can meld the space around them to enable FTL travel, or some kind of indestrictuble, invincible metal, then this ayyy shit is fake and homosexual. Sprint Missile:

So if they've invented FTL drives, why haven't they colonized the galaxy? We can't see any Dyson Spheres near us and they clearly haven't tried to suck the energy out of our galactic core. Either they're cuckolds who refuse to reproduce and create a glorious, galactic empire, or they're fake. Either way, I doubt they'll interfere with us. That is, unless they're so scared of our power that they have to.

>>12013001
Like I used to think that nuclear propulsion was the best way to go with the relatively high isp, until I saw the fact that chemical propellant has 10x or more thrust then nuclear. Whoever likes nuclear rockets better be willing to wait a looong time before actually reaching the planet they want to get to.

>>12013020
That's why I provided Sprint as an example. Unless the UFO's could use an Alcubierre like drive to move matter around them, the speeds that they would be travelling at would turn the air to plasma. Plus, the g forces put on the crew/robotics would probably be enough to destroy it. It's either FTL magic or nothing.

I might be wrong about this but I thought the appeal of nuclear propulsion was the greater fuel efficiency which leads to an exponential growth in speed as it fires longer?

>>12013057
If you have the means to accelerate at tens of gees at right angles with no exhaust then yes, the current laws of physics are laughable.

>>12013088
There's no substitute for thrust. You'll still need chemical rockets to land on Mars and take off again.

>>12013051
>It's either FTL magic or nothing
>t. planet bound monkey who can't even send one of their monkeys to the nearest planet

>>12013096
Yeah, so? That's what having a lander is for. Chemical rockets are pathetic for manned transfer times to Mars.

>>12013088
Yes, but if you think of it as X (being the thrust value in Newtons) and Y (being the isp/efficiency of the fuel (aka can burn longer))
Chemical rockets: 10X x 1Y= 10XY
Nuclear rockets: X x 2Y= 2XY
This is simplifying the process, but this pretty much means that chemical rockets are 5x as effective as nuclear rockets currently. (Used Raptor Engine for chemical, NERVA for nuclear)
