Job security.

Spending the entire 21st century "researching" micro-gravity lets you spend the 22nd researching low g spin. With the right mindset you could arrange jobs for your bloodline for the entire millennium while slowly working your way up to 1g. And the best part is - why stop there? Spin harder. Work harder. Infinite g infinite j.

>>15422095
Could you use a linear accelerator combined with laser thermal ramjets for a first stage? With no onboard propellant, few moving parts and an ground based power source you should be able to get really good thrust to weight ratios. I'm sure it's a bad idea, but can someone explain why?

>>15422205
meds. now.

>>15422217
easier and cheaper to just build a two stage rocket.

>>15422217
>laser thermal ramjets for a first stage? With no onboard propellant
What is the fuel?

>>15422217
Suppose you try to get to ramjet speeds (~mach 3, ~1 km/s) at 5 G. Much more acceleration will probably kill your astronauts. Then you need about 20 seconds of acceleration, during which time you travel ~10km. Maybe it would work with a laser turbofan instead?

>>15422236
The propellant is atmospheric air and the energy to move it is beamed from the ground

>>15422223
Yeah, fair enough. Even if you could get it to work the required infrastructure would be insane

>>15422255
we're trying to do the equivalent of trucking or shipping on earth. yea you could build an autistically efficient memetech ship that got things port to port for the lowest possible fuel use/cost but if it disintegrates on every voyage and you scrap it it after what really was the point vs just building out?

>>15422246
Laser beam spread is negligble at 10km so that should still work assuming sufficiently accurate beam guidance. Hell, you could probably get it all the way up to 2km/s, then stage, cut the beam, and have the booster glide back.

>>15422252
Fuelless ramjets don't exist

>>15422197
retarded

>>15422277
Sorry, are you saying they're conceptually impossible/impractical or just that no one is using them because they haven't been developed yet?

>>15422274
I was just thinking 10 km is pretty long for the linear accelerator, especially if it's intended not to be completely horizontal

>>15422287
They were developed and deemed impractical for aircraft, forget something pushing thousands of tons.

why would you develop ram/scram jets instead of just leaving the atmosphere and going faster anyway?

>>15422290
Why use an accelerator at all? Just put wings on the booster and use the laser to feed the engines.

>>15422323
Yeah, that's a good idea but then you need a more complex engine that can run while stationary

>>15422327
Jet engines are not actually that complicated compared to 10km long linear accelerators.

>>15422320
potentially lower cost and higher performance if you don't have to carry your first stage propellant and can reduce the complexity of your engine, although that's only a reasonable argument if there was a practical design with those properties

>>15422329

How do we mine uranium on the Moon?

>>15422357
You don't. You mine it on Mars.

>>15422357

>>15422357
nobody knows, except for the fact that the mining equipment we use on earth probably won't work due to the very low g.

>>15422343
Assault cars must be banned
>>15422357
Uranium fuel is not expensive or supply limited, it isn't even 1/10th of the cost of a nuclear power plant per MWh and it will never be mined on the Moon economically.

>>15422383
Have there been any proposed technologies for mining in such low gravity

>>15422390

>>15422357
>A solution is to harvest fertile thorium on the lunar surface, then transmute it into fissile uranium using the gamma ray fog which pervades the deep sky. It is only at lunar orbit, at the very edge of cislunar space, that the Earth-launched machine becomes a nuclear thermal rocket (NTR). Thorium is not abundant, but can be concentrated by mechanical methods because of its very high specific density relative to the bulk of lunar regolith. Thorium dioxide (ThO2) has an extremely high melting point, such that skull crucible heating can be used to separate it from supernatant magma. When filled into a graphite-lined beryllium container (brought from Earth) and set out on the lunar surface, high-energy gamma rays will liberate neutrons from the Be. After moderation by the graphite, these thermal neutrons are captured by the thorium nucleus, which is transmuted into protactinium (Pa91). This element can be extracted using the THOREX process, and will then decay naturally into U-233 within two or three lunar days. The uranium is oxidized and packed into fuel pellets, ready to be inserted into a non-radioactive machine, which now becomes an NTR.
https://www.sciencedirect.com/science/article/abs/pii/S2468896721000604

Great a trillion dollar NTR, meanwhile unrefined uranium is ~$50 USD per kg

This has me pondering, once space access is cheap enough could we cure/alleviate some physical problems by sending people to orbit and treating them there? Weightlessness might help

>>15422477
not my point. this is a 50 ton totally unoptimised excavator used in mining. you could ship two of these plus spares on one starship and not bother with the autism vs just mining like we know how to.

You will never live on a spinning ball. Earth has no curvature, It doesn't move, It's flat. You are a troll paid to shill a twisted mockery of nature’s perfection. All the support you get from your boss and fellow paid trolls doesn't change the fact that you are a cancer upon humanity. Your life is worthless. Your parents will be disgusted and ashamed of you if they knew your job, your boss laugh at how useful you are to globohomo behind closed doors. Truth-seekers are utterly repulsed by you. Thousands of years of evolution have allowed men to sense frauds with incredible efficiency. Even globetrannies who try to pass as Flat Earthers seem dishonest and unnatural to a discerning man. Your behavior is a dead giveaway. And even if you manage to get someone to believe you, he’ll cringe and go flat the second he sees the awful, condescending way you treat flat Earthers. You will never be happy. You wrench out a fake smile every single morning and tell yourself you're going to be ok, but deep inside you feel the guilt creeping up like a weed, ready to crush you under the unbearable weight. Eventually it’ll be too much to bear - you’ll buy a rope, tie a noose, put it around your neck, and plunge into the cold abyss. In the afterlife you will feel heartbroken but relieved that you no longer have to live with the unbearable guilt. God will send you to hell, and he will know for the rest of eternity he sent a liar there. Your body will be tortured by demons forever, and all that will remain of your legacy is a consistent effort to try to hide the truth from people. This is your fate. This is what you chose.

the obvious bare minimum:

cover up hydraulic pistons from dust

Jannies cant do their one fucking job I cba

>>15422513
Sure, you can put excavators on the moon. The only reengineering you need is everything. Even if a part will still work fine it’ll still be triple checked for every eventuality. You can bitch about oldspace over-engineering, but it wont change the fact that we’re 3 generations of lunar excavator away from them being streamlined. Expect it to take decades for them to go from 1 bil a pop to 10 mil a pop, and thats if theres a reason for us to send more than 1 and give up.

Nuclear thermal rocket engines have at most few tons of uranium, a dedicated mining operation with fuel enrichment and assembly would cost hundreds of billions and require thousands of tons landed on the Moon. The idea is pants on head retarded, before getting into issues with the propulsion itself.
> this is a 50 ton totally unoptimised excavator
The CAT 350 is ICE and wouldn't work on the Moon. Even electric excavators would require extensive modifications for such a purpose and a large power supply

This was NASA's idea for a moon miner.
Note that it doesn't look anything like >>15422483

>>15422535
it scoops kgs of regolith at a time, it doesn't move earth. how will you build a launch pad or prepare the ground for habs with that pos?

>>15422535
Wasn't there some concept with some tethered dragline thing that would scoop stuff from the surface slowly getting deeper?

>>15422530
We should double their pay.
That'll get them working.

>>15422547
That will be a parallel development to lunar cable cars

>>15422534
If you're going to the Moon exclusively to mine for NTR fuel, yes it's a bad idea. However, if we're trying to set up a colony and extract resources anyway, it's certainly doable. All you need to do is just smelt leftover regolith and put in a jar once it cools

would chemical propulsion work to get into orbit?

>>15422638
don't be preposterous. the only tried and true way of getting to space is by spinning really fast

>>15422563
It's not trivial to create uranium fuel assemblies even if you somehow had a pile of raw uranium left over from other operations. There is literally no demand for it when they could be produced cheaper on Earth and their mass is virtually nothing compared to all the other shit we send to space. I said a few tons at most but it's more like ~50 kg for a HEU nuclear thermal engine and ~300 kg for LEU engine like INsTAR.

So optimistically demand by 2050 could be a few tons, realistically it will be zero tons outside pork projects because no one in their right mind would build an NTR for something that can be done by chemical or electric for a fraction of the cost and their unnecessary use isn't politically viable, they're already defacto banned from LEO.

why wouldn't a very long liner accelerator to orbit work?

>>15422660
The answer to this is the same as the answer to every other question asked in this general: it would but no one wants to shell out the $200 billion to get it built.

>At a conference a few years back I quizzed a NASA official who advocated a multidecade program investigating zero-gravity health effects on humans prior to a piloted Mars mission. “Why not just employ artificial gravity?” I asked. “We can’t do that,” he said – “all our data is going to be for zero gravity.” Get the picture?

It’s interesting how after the moon landings, film technology and cgi saw a major renaissance of leaps and bounds in advancement while rocket technology suffered a catastrophic slide backwards that we have never recovered from.

>>15422526

It's not limited to just Starship, old space and congress have done everything in their power to impede a manned Mars mission done with chemical propulsion since von Braun first proposed the idea over 70 years ago. They drew a line in the sand, if it was going to be done, it would be with nuclear and be the core justification for its completely civilian and benign use in space, wink wink.

NASA's current Moon-to-Mars Architecture tells you everything you need to know, they're even attempting to preclude its use for cargo missions which is just insane. Luckily SpaceX is independent and Starship will still likely come out on top even if they bias the results of the research, but it's still annoying to see so many space "fans" fall for this shit and then back old space because it appeases their sci-fi influenced concept of how a Mars mission should be done. All I can do is keep ringing the alarm bells.

You 29 posters are my only true friends on this earth. Let me share a story from earlier today... So I was at the local chinese buffet and I noticed people were looking at me strangely. Eventually noticed they where using hand symbols and other strange methods to communicate to each other about me. I could feel the skin on my face getting hot and turning red. This only strengthened the misplaced strength they though they had. As I went back for my 3rd plate I was loading it with wontons and cheese crab bake. I could hear their voices in my head, by analyzing the inverse of their body language. They all thought I was a pathetic insane monster. I felt sad for them, but also for myself, that I am in a world where people are treated like this. As I left I gave the counter attendant a 30 dollar tip, even though she did nothing but ignore me the whole time, as random people filled my diet Pepsi as I ate. I'm not even sure if they worked there. Not even sure if I was actually at that restaurant to be honest. Physicaly I was, but I don't think I interfaced with what was supposed to happen...

NTA but I have a handful of diamond tipped cutting bits for my dremel. Industrial diamonds are great for abrasives but we can't make them as big as natural diamonds, to my understanding. also to my understanding diamond manufacture in space would fix this.

>>15423074

>>15422883
It's not just HEU or the possibility of secretly enriching lower grade uranium that is a problem, any fissile material can be deorbited and cause dangerous fallout over vast areas. Even RTGs, despite emitting very little radiation, can kill thousands of people if they reentered at a certain angle, which NASA sheepishly concluded with their risk assessments on Cassini–Huygens.

Which countries would you allow to operate nuclear stages? What is to stop acts of terrorism if they're allowed to operate in LEO? What about the risks of engines failures and space debris? I get that the average person here is a sci-fi loving teenager but we're probably looking at the eventual ban on nuclear spacecraft unless they're assembled and depart from an Earth-Moon lagrange point. Hell they could already considered a WMD as per the Outer Space Treaty, like GW scale lasers.

No rational person would want to set spaceflight back decades if not centuries by pissing off a bunch of Earthers with a worthless idea like solid core NTP cislunar or Mars tugs and it's not a fight that you will be able to win because the amount of people that have concern, valid or not, about radiation is much higher than the amount of autists who believe everything nuclear must be superior despite that obviously not being true.

Have they stopped trying to recover the 1st stage?

This is a steep trajectory, no?

>>15423323
Yes and no. They're still fishing a select few out of the ocean, but gave up on catching.

2nd stage is a little wobbly today (not as bad as Falcon 1 I hope)

>>15423324
Does seem like it. Normally we would've seen the horizon at least a minute ago.

Fuck you old battery!

>>15423324
It's a weird payload for Electron. A 3U cubesat is something you'd normally expect to either fly as a rideshare payload on a much larger rocket or as a solo payload on something that's more in Astra's weight class.

is astra seething right now?
also TROPICS should have launched on starship

I liked the brief shot of the battery alone falling away

>>15423328
Look at the altitude, it's steep as fuck.

>>15423324
>>15423328
It's a 11kg payload so the gravity losses on the second stage is lower than usual.

>>15423332
>Electron is flying right now

>Launch satellite to monitor the planet
>Jettison trash and batteries that pollute the planet

>>15423331

>>15423337

Nice dogleg

FYI

they actually throw car batteries in the ocean?

>>15423335
>11kg
That's less than 4% of Electron's payload capacity. This rocket practically launched empty.

>>15423285
>Will rotating detonation engines make the Raptor obsolete?
Nah, Starship will have been operational for awhile before RDEs are used in a serious capacity on a launch vehicle. They might be worth exploring for a larger Starship successor, though. Since RDEs rely on combustion instability to operate, they ironically should avoid the instability issues seen in larger constant pressure engines like the F-1. A decent chunk of large liquid engine design efforts are directed towards stopping various instability modes, so if that can be avoided, development costs would likely be lower.

What matters is delta-v. See >>15423344
It's obviously a high performance mission because they still need a kick stage for changing the inclination.

Either way, RL is based for having them.

Also, booba, feeta.

>>15423364
All I know is they ditched them on the CAPSTONE launch to maximize performance

>>15423370
Seems they want a low inclination and New Zealand isn't in the tropics

>>15423370
I think only that initial right turn was commanded, then once it starts turning left it looks like it's on an inclination.

>MH: Is weightlessness more likely to give you a boner? Just the lack of ball sag alone would make me want to text a picture to someone.

>Mullane: In weightlessness, one of the physiological changes is a fluid shift. Your blood and fluid is equally distributed in your body. So that makes your calves and thighs and waist skinnier, and it makes your chest and women's breasts broader. The downside is your face is kind of puffy. If you look at astronauts closely, their eyes look kind of puffy. And it gives you this mild headache. But one of the advantages of that, if you will . . .

>MH: A bigger boner? Yes!

>Mullane: A couple of times, I would wake up from sleep periods and I had a boner that I could have drilled through kryptonite.
