Paraterraforming gang claiming first post

I can't believe the future of space travel looks like a water tower that is crudely made from the junkyard.

Will Virgin Orbit work or will they be picking up pieces of 747 from the Mojave next week?

>>12560981

Remember, mars fines are actually not a hazard even in the slightest and any statement to the contrary is baseless FUD.

>>12561015

Wouldn't be a bad ISR platform in orbit.
But such programs are already in development, and will be able to operate at a much cheaper cost.

Deploy an autonomous vehicle, grab it roughly and fire an SRB to deorbot.

>Deploying meatbags to physically board a station

Absolutely retarded, no orbital fight is going to result with anything less than the enemy being a cloud of shrapnel so better make sure your dudes aren't on board their station or in fact any vessel in conflict. Meatbags are fucking useless in space battles except as overall command.

>>12561020
A USAF Starship wouldn’t use that logo on the vehicle. It’d have the standard roundel.

>>12561024

>>12561023
Yeah but Starship looks cool though. I’m not memeing either it looks badass and it’s imposing as fuck

I swear to god if someone breaches the perimeter again on launch I will kill someone

>>12561031
You mean this?

>>12561026
Coast Guard style actions end with boarding and ramming all the time. Not everything is a shooting war.

>>12561044
Also blasting someone away isn’t always a good thing especially with space debris or having to retrieve delicate cargo.

>>12561043
Yes.

>>12561049
>blasting someone away isn’t always a good thing
Go back to Woodstock, hippie.

>>12561044
Coast guard actions aren't against armed foreign military vessels. If they were the results would be pretty fucking different. Even then, some rogue trader who has a little machine gun could make a fucking mess of as many starships as goes near it, they are so fragile and prone to exploding.

>>12561044
Even battles at sea are moving more and more towards unmanned shit and smart missiles.
If you can launch 8 of pic related from a single ultra fast skjold class corvette linked up to one another that does random maneuvers and terminal bunts, your boat full of able seamen are fucked no matter what.

Those corvettes are stealth and have a top speed of 60 knots by the way. War is not the same anymore, if you're in space, you're not bringing out the fucking boarding axes either.

>>12561072
Definitely. They’d probably use the low-vis version of the roundel, but the full color looks way nicer with the blue.

>>12561075
Okay, but if you're strongly suggesting a fishing vessel fuck off out of your waters, you don't send missiles. Likewise, not every conflict in orbit is best resolved with blowing the target up. Seizing it, or even boarding it for inspection, is always an alternative.

>>12561064
>He doesn’t want to pilot a nuclear launching platform
Heh...get a load of this guy

>>12561075
Ok but on the contrary many ships have anti-missile capabilities.
>Pic related

>>12561087
You do know that's not a normal missile, right? Good luck shooting it down. There's a reason the US bought it over their own shit.

>>12561087
They’re replacing the CIWS systems on most ships with RAM or Sea Sparrows these days. Guns aren’t seen as a particularly reliable option in the face of modern threats.

>>12561079
Realistically that is never going to happen, at least for a very long time. Boats are not spacecraft. Spacecraft are and will remain expensive enough to operate that all flight plans and cargo loading procedures will be followed exactingly. If you try to board another countries vessel then expect violent retaliation.

>>12561092
Could an EMP disable an enemy warship?

>>12561093
No, probably not. The effects of EMPs on things that aren’t large pieces of infrastructure with hundreds of miles of wire are often overstated.

>>12561093
Everything these days and for quite a while in the past has been EMP proof, it's actually not very hard to do and any space warships will absolutely be shielded.

>>12561100
>>12561098
>Bro’s....please tell me close quarters warship combat is possible....I want to believe....
Just kidding but seriously though wtf so there’s no CQB in space? That’s super anti climactic

>>12561106
There could be circumstances where CQB is a thing, say you were trying to seize an immensely valuable asset that neither side was willing to scuttle, however that kind of operation would be exceedingly rare. For the most part, no. Realistic space battles will be somewhat analogous to submarine warfare, involving ships light seconds/minutes apart that have the most advanced heat storing and light absorption systems available to minimise their signature beyond the enemies passive detection capabilities, dropping delayed activation smart missiles towards where they think the enemy is.

>>12561106
The guns in the show are super slow firing compared to real world CIWS, if they were really rotary cannons then both of those ships would just shiver and fly apart into clouds of debris as soon as they opened fire on each-other.

>water propellant is super duper volume efficient at 1000kg/m^3
>strapping a cockpit to an overpowered undersized spacecraft in general
Really the only thing I can't figure out a tech-tree route for is the weapons. FTL is a non factor since in-setting they communicate with the jumpgate over regular RF and ships don't need any special equipment to survive once inside hyperspace.

>>12561013

>>12561195
You need to read about a little hiccup called waste heat

My question is this.
During launch of starship, presumably with near capacity passengers aboard, will they sitting in like, airplane style rows for launch? Or will the living quarters be fitted with seats facing the proper direction for launch?

Are there going to be incidents of people trying to fuck during launch in case of the latter?

>>12561209
You mean a colony ship? I assume they'd just be strapped into their beds for launch.

>>12560971
When do you think will be SN9's flight?

>>12561212
Yeah. I just wonder if there would be space to include a proper sitting (or strapped-in) position for everybody onboard, or how they would go about that.

>>12561209
Mass transport such as E2E or to a LEO space station will be 800+ seats fitted in rows to suit launch and landing directions. Colonisation ships to Mars will have individual cabins that fit a gimballed crash couch that breaks down into a bed for the duration.

>>12561218
>gimballed crash couch
Okay, NOW I'm hard.

>>12561220
Thinking about it, actually all passenger types would need gimballed crash couches since the g force is experienced in different directions for launch and re entry. I guess you could have a dual mode seat that you would unbolt and rebolt depending on what maneuver the ship will be doing next but that opens up a liability issue so probably a one size fits all gimballed couch will be developed is my guess.

>>12561226
That's how they're going to deal with the g-forces encountered during the land maneuver then? I can't think of any other way

>>12561209
>>12561218
>>12561226
>Thunderbird-1 style rotating chairs

>>12561214
13

>>12561209
We simply dont know until they show us their concept for the insides.

>>12561231
The g force during the flip and burn for the landing is fairly negligible and goes on for less than a minute so that's not really the issue. It's more the g force pulled during the belly flop where the vehicle experiences the longest and largest deceleration from orbital velocity.

>>12561184
アエイオウ豆腐

>>12561240
Ah that makes sense. If these launches are frequent enough that the experience is pedestrian I could only imagine what people may attempt to do during launches/landing.. maybe I'm just being cynical

Niggers you don't need gimballed couches, you only experience significant gee in two directions. Refer to my over 9000 hours in mspaint drawing.

Thud Octaweb is the ultimate KSP engine config

>>12561253
So what then. Hydraulic couches? They change seats midway through landing?

>>12561266
The couches haven't changed position anon, can't you manipulate 3d objects in your mind?....

>>12561270
So then they're upside down during the bellyflop?
Improve your artwork before you try and get snippy with me, buster.

>>12561278
No they will be spinning to generate their of G-force the negate the ships

>>12560981
I can't believe the future of space travel is being cut up and thrown in the junkyard to make way for the hot new thing (a shinier version of itself)
we live in a society

>>12561283
Yes
You may be oversimplifying the forces present during reentry tho

>>12561283
the arrow on the right makes no sense and there are no stick figures to show what positioning the passengers are supposed to be in. Maybe spend 10,000 hours next time

>>12561289
It's close enough to make no difference, there may be forces applied forward or backward of the seat during re entry, but not significant enough to be worried about.

>>12561291
Are you fucking retarded? They are sitting in the seat in both examples like your fat ass is sitting on your greasy gamer chair right now.

>>12561297
Neat. I'm sorry for criticizing your artwork anon.

>>12561297
I don't usually sit in the fetal position or standing up on the chair either. No idea what the Ls are supposed to be representing

>>12561283
reentry is at 70 degrees instead of 90 degrees, there's a significant element of lift too

>>12561304
L is a chair
retard

>>12561308
Weird chair man. Is the short side a footrest or something?

>>12561312
draw a chair for me please

>>12561305
I used 90 degrees for the mentally impaired, clearly that hasn't made things better for the terminally autistic. Whatever angle you change it to doesn't change the g force direction of force applied against the craft, as far as lift goes, sure you will get some which will be relieving the main force in the opposite direction and possibly applying some directly against the chair. It's not significant enough to worry about.

>>12561312
>why isn't your two minute mspaint shit drawing visually perfect

take your meds you autistic fuck

>>12561314
agreed, although I independently reached a similar but different conclusion as you
I think it's better to have your back to windward so you're laying down during the high-g reentry and then sitting down for the landing burn

Redpill me on mini starship

>>12561322
It's pointless now that SN8 bellyflopped correctly.

>>12561322
it's smol

>>12561320
I thought launch was the more significant gee force which is why I angled them that way, the flip and landing burn is short enough to be who cares which way you are facing so long as you are strapped in.

I wanna know more about this chair.

>>12561328

what if we strung everybody up in hammocks running from port to starboard so they were free to pivot from hanging towards windward to hanging aft

>>12561319
who said anything about visual perfection? there was a discussion about airline-type seating vs passengers being strapped to their beds. when you draw a line with the bottom basically flush to the outer walls i'm assuming you're depicting the latter, no?

SpaceX have just swapped from 304L to 308 stainless

>>12561339
Based

>>12561341
This was my first thought and still my favourite idea, low weight and great on space, probably needs a semi rigid member along the spinal axis so you don't form a u shape and break in half. Not great for convincing passengers and safety authorities though so probably won't fly for a while at least.

>>12561347
Stop being autistic you stupid cunt

>>12561359
comfy space hammocks though

>>12561362
Like I said I agree and think it's the optimal solution, especially for colonisation ships where you spend up to half a year or whatever in zero g, a strap in hammock is perfect. But you gotta convince people your hawaiian chill hammock is safe for atmospheric re entry.

>or reactor

>>12561578
Well this looks really damn sketchy.
The plan was in the air for only 4 minutes and got up to just over 10,000 ft in the air at 287 kts. The plane turned about 30 deg counter-clockwise, and dropped 2000ft and about 60 kts. It then turned back clockwise 30 deg, dropped another 3500ft and 110 kts. It spun another 80 deg clockwise before almost reaching the water. The interesting thing is that the last chunk of data before loss of contact shows the plane at 250ft, but suddenly going 350 kts. I'd assume that's a sensor error, because they would have accelerated a whopping 240 kts in a matter of seconds, while falling from the sky.

they can, but there is a massive problem with asian education system compared to the west.
Western education makes you apply the things more that you have learned, asian education just makes you learn everything there is and thats it.
It also doesn't help that the school system there is massively corrupt and you pretty much will get your degree if you pay enough.
in other words, chinese docters from rich families who failed their classes but were passed anyway are operating on people all the time in CCP china.

>>12562080
Meh, Prabu had a more insightful post than EA usually makes and Elon responds to him all the time.

>>12562073
Don't believe American propaganda. Brownouts are caused by new factories built in Guangdong. The demand is getting high and the electricity production can keep up. China is not running out of coal. China can buy from other Asian countries like Indonesia.
Back on topic. China can potentially be a competitor in the second space race. Maybe after the Americans realize they can't compete economically with China they can try excelling in science. Triggering a space race should boost space exploration R&D. Why do (You) hate China again?

>>12562081
It's a cheap energy source unlike meme windmills. Beside, the usage of coal is declining and they are planning to become carbon neutral in 2050.

>after you pissed Australia off and they reduced export?
Oh no, Anon, it's even funnier than that. Big mighty China (the glorious Middle Kingdom of 1.4 billion, to which all the good things on Earth and Heaven flow) claims they were being 'bullied' by Australia (a nation of 25 million people on the arse end of the world who were beaten in war by some large birds), so China decided to punish Australia for their impudence by cutting imports of all their products (lobsters, wine, timber, coal) for spurious reasons that are evidently bullshit to anyone with half a brain.

In that finest of Chinese manners, after several millenia they still don't understand how to perform diplomacy with their 'lessers' acquaintances and have decided to cut their nose off to spite their face. Australia's coal is of the kind of high quality required for steelmaking, you wouldn't waste it on power generation.

Of course, now that they refuse to import Australian coal they instead are having to use thermal coal normally reserved for power plants. This results in lower steel yields, but the Chinese steel industry must carry on at its current level of output regardless of efficiency because otherwise the level of layoffs required from scaling it back would cause immediate nationwide revolts due to the massive unemployment.

They can't divert the thermal coal back to its usual uses. They have to keep using substandard coal to make steel or their economy will implode. All of this effort, just to 'punish' Australia for not bending over and taking it in the ass.

They're fucking idiots. As long as they continue performing diplomacy like this (like a giant tantruming child with no sense of finesse) I'm not particularly worried about them becoming *the* superpower. No one likes cooperating with them. The future is multipolar.

>>12561978

mostly because you treat your workers like utter shit so if you conquer us well have to work like that too.

Americans treat us like shit but much less, also their culture is cool as fuck with netflix drugs rock and heavy metal.

We are clearly dominated by the us empire and it sucks but it would suck 1000x more if we were dominated by the chinese, promise us standards of living higher than those in mexican sweatshops and an interesting culture and maybe well switch sides.

Well, the western education is in massive decline because of race bullshit and actual communists infiltrating every aspect of it, no denying that.
But the asian education is still even more shit, there is a good reason why so many rich asians send their kids to foreign universities.
And chinese scientists are known for manipulating scientific tests a lot to get the desired results, this is a problem too in the west but a lot more in asia.

>>12562068
Chang'e 5 was pretty impressive tho, and they at least already try to test reusability with Long March 8. But yeah anyway to catch up with spacex it can take 5-10 years for them

>Many developments criticized as ghost cities did materialize into economically vibrant areas when given enough time to develop, such as Pudong, Zhujiang New Town, Zhengdong New Area, Tianducheng and malls such as the Golden Resources Mall and South China Mall.[11] While many developments failed to live up to initial lofty promises, most of them eventually became occupied when given enough time.[7] The "ghost city" moniker has been criticized for "calling the game at halftime"
Anyways, what do you guys think of the Long March 9 rocket? Supposedly can carry 140t to LEO. I wonder if they can compete with Starship.

>>12562130
Yep, and Wade Shepard and Kai Caemmerer were bought off by CCP?

>>12562108
If China's educational system is so superior, why the fuck did they send so many hundreds of their bright youth to my uni to crowd out everyone else in business and STEM courses?
Not salty about that directly, but it does make me wonder why they'd rather study here, as opposed to in China? I'm sure it has nothing to do with the outrageous number of Chinese professors, researchers, and private contractors who end up being charged with IP theft and industrial espionage, totally above board they just want some culture exchange right?

>>12562129
>But yeah anyway to catch up with spacex it can take 5-10 years for them
Provide your timeline. As you said, they are "testing reusability". They don't even have a Falcon 9 competitor in the cards yet, once they have done their testing their plan is to move to a reusable smallsat launcher. To put it into perspective, Starship is more developed than China's partially reusable smallsat launcher. "Catching up" with a moving target isn't even on the horizon. I'm saying they'll be roughly where the west is with SpaceX now, in 20 years. SpaceX will be, if anything, pulling ahead at that time.

Deep down they do but Scott lives in California and has kids named Sky and Orion trust me he would rather cancel spaceflight altogether than support a conservative. A funny thought experiment is his view of Elon.

>>12562301
Aerospike, commonality of sea level and vacuum engines plus superior overall propellant utilization curve is IMO a worthwhile tradeoff against maximizing TWR or ISP.
Plus, worth considering that the only aerospikes that actually reached maturity were utilizing plumbing from already existing converging/diverging rocket engines, and I always wonder if they would not have performed better if they had been designed from the ground up.

>>12562316
This is untrue. Dedicated sea level and vacuum engines mog the fuck out of aerospikes and they are cheaper to build on a per unit basis. Aerospikes are complicated as hell

>>12562311
>kids named Sky and Orion
Why do parents do this to their children, do they not stop and think about the choice they're making? Imagine growing up named "orion".
Elon's not innocent here either, the fuck was he thinking with his new kid's name? It's like everyone wants to be unique and quirky while naming their children but don't realize that a person has to live with that name for the rest of their life.

i would name my daughter andromeda desu, rate

>>12562326
>Sky and Orion are bad names
Nigger, you ain't seen shit.

>>12562319
You're basing this on the two aerospikes that actually made it to maturity I assume, the RS-2200 and J2 Aerospike? Those aerospikes built as experimental nozzles based off of two of America's most expensive and complicated LOX/LH2 engines, where components for the aerospikes had to be hand-machined and tooling for them had to be invented from scratch because none existed before?
I don't think you're being exactly fair to the concept.

>>12562348
>Spend less time building two different types of expansion bell.
>Utilize your propellant more efficiently throughout the burn.
Seems like a trade worth considering if your goal is to build a lot of rockets which are going to be flying constantly, almost like that tradeoff where you sacrifice maximum TWR and maximum ISP from either KeroLOX or HydroLOX in favor of maximum economical performance with MethaLOX.

>>12562326
what I don't get is why nobody names kids after people who were influential in their life like their parents or grandparents. If my kid has a child and names it something stupid instead of after me, the person who raised them, I'd be a little pissed 2bh.

would an aerospike be safer / more redundant than a bell engine? Doesn't it feed all the engines to the same 'bell' (the spike) but there are multiple nozzels per engine and you could tie them together or something so that if 1 engine failed it's nozzles can be supplied by the other engines to keep the forces on the spike equal?

>>12562341

>>12562361
I was named after my grandfather. He just has the same name as my father

How much fuel/oxydizer does a propulsive landing take anyway? As a percentage of the total they're carrying. i assume it's a small amount since the drag does most of the work. maybe the starship second stage will need more to help come down from orbital velocity, even if the bellyflop does the lion's share

>>12562366
10 percent. My dad works at spacex

>>12562364
My dad named me something different specifically to spite his father, but it's better than being named after a Game of Thrones character

>>12562362
Yes, there are many simple nozzles feeding into an aerospike, if any one fails out it's direct opposite on the other side of the ramp/cone can also switch off with only a very minimal reduction to overall engine performance. The ramp is under higher thermal stresses but active cooling eliminates this issue and new methods of building engines with cooling channels will reduce one of the aerospike's original problems which was that like the RS-25 it needed many small welded cooling pipes which was complicated and cost mass. Nowadays an additively manufactured spike or ramp would eliminate this issue. The structural stresses on Aerospikes are less, they are not containing the enormous pressure of a full sized combustion chamber, the atmosphere does most of that work and the narrowing shape of the spike transforms pressure inward on the spike into propulsive force that pushes the whole rocket forwards.

>>12562366

>can only be reused 50 times
kek, raptor engine is far better

>>12562359
Yes, making an engine bell is much harder than a meme engine under performing in all flight regimes but sadly its the way forward. We do the hard things because they are hard.

Where's the new thread at niggas

>>12562385
Anon the thread is on pg 1

>>12562366
termimal velocity + gravity losess + hovertime.

Very complicated calculation. Triple the terminal velocity and you'll probably be safe.

>>12562377
would you want to turn a nozzle off though? Wouldn't that cause the adjacent nozzles to have some room to flare sideways to the gap? Can't you just connect plumbing like so so that if engine 2 failed, it's nozzles are still getting supplied by the other engines, only overall thrust of each nozzle is reduced (unless you throttle up to compensate)?

>>12562350

>The future is multipolar.
The future is limitless expansion into space, and the selection pressure there will be for the fastest growing societies beyond all else. IN order to preserve western ideal, and I'm being serious here, our best bet is to get a self sustaining Mars colony with a high proportion of mormon colonists.
Just like turning a clearcut back to old growth forest, the first wave of trees need to be fast growing softwoods, which rapidly take over and establish ground cover which can shelter the more long lived and larger hardwoods. By analogy, get an expanding sphere of mormon colonies passing through the universe, and a few thousand years after they show up the societal ideology will transition from focus on growth to focus on sustaining and developing complexity/sophistication.

To be fair, Angara is a known white elephant, basicaly their equivelant of the SLS.

The Soyuz-7 is a vast improvement on every level for the Russians so yeah, it is what Roscosmos realy needs.

>>12562472

>>12562316
>plus superior overall propellant utilization curve is IMO a worthwhile tradeoff against maximizing TWR or ISP.
Dude, a bell nozzle always gets more TWR than an aerospike and also always gets more Isp at its design altitude. For launch, TWR matters more than anything else, and at sea level a sea level bell gets both higher Isp and higher TWR than an aerospike. The first stage burn of a reusable booster only lasts a couple minutes, then stage separation occurs and the upper stage with its vacuum bells takes over, offering the best TWR and Isp. There is LITERALLY never any reason to use an aerospike on Earth, our atmosphere is not thick enough for it to ever be worth it.
As for commonality of nozzles between stages, no. That's a dumb argument. SpaceX has proven that you can have two nozzle variants of the same engine without much hassle, with both Merlin and Raptor at this point.

>>12562336
The tech is a dead end, dude. Give up. Nobody will do aerospikes until we're building SSTO craft for doing launch around Titan.

>>12562359
>>Utilize your propellant more efficiently throughout the burn.
Aerospikes are less efficient at sea level and less efficient in vacuum. They are less propellant efficient over the course of an entire launch except for the last minute of the first stage burn, which is not nearly enough justification to sacrifice performance during the previous 2.5 minutes of first stage burn and subsequent 7 minutes of second stage burn.

>>12562366
>How much fuel/oxydizer does a propulsive landing take anyway?
The amount that is stored inside the header tanks, buddy. ie very small fraction.

>>12562477
If it actually ends up being as reliable as Falcon (and previous Soyuz rockets for that matter) it could actually make Roscosmos become a positive profit maker on top of just actually being able to pay for itself easily. They could reduce seat costs by a large margin (assuming they put a capsule ontop of this thing ever) and still make a shitload more than they would with their expendable Soyuz launcher, on top of doing cheap cargo and milsat missions.

I might not buy that China will become the world's new superpower and I certainly am dubious that they will make as much progress in space as they claim they will, I would not be surprised at all if they completely BTFO SLS.

>>12562498
NOOOO ELON MUSKU PREASE!!!!!

>>12562500
Anon even New Glenn BTFO’s SLS.

>>12561651
After musk did it first he became a convert
Unfortunately parachuting into the Atlantic ruins it so there will be no effective reuse

>>12562500
>BTFO SLS
That's trivial for anyone who wants to build a rocket. It's impossible not to beat the SLS if you try building a heavy lifter. SpaceX already did it with the FH.

>>12562512
the helicopter catching thing will happen in 2021 imo

>>12561865
Solar is better power by weight than any reactor ever made and no one in the US is even making reactors

>>12560971
Could SpaceX give Falcon Heavy a 5 meter wide upper stage? How close is Falcon Heavy to BTFO’ing SLS?

>>12562519
uh, bro?

>>12562520
won't happen. not at all worth the rnd with starship first orbit well on its way

>>12562522

They kinda bundled starship naming, eh?
'Starship' is alright, not exactly inspired but serviceable, and the whole super heavy thing is confusing at a glance.

>>12562377
>The structural stresses on Aerospikes are less, they are not containing the enormous pressure of a full sized combustion chamber
Completely wrong, the combustion chamber of an aerospike is effectively 10x to 20x bigger than the combustion chamber of a bell nozzle, and atmosphere does nothing to contain any of the gasses inside the combustion chamber. Remember that the aerospike nozzle is only a NOZZLE, there is no real difference on the actual power head side of things, except for increased difficulty keeping the proportionally much larger combustion chamber area cool.

>>12562072
If you are actually building real estate for people to live in you will always have “empty” cities for periods of time

I keep my screen brightness down when I'm in the dark and it makes it harder to distinguish between orange-red and red-orange, not my fault when there are at least a dozen completely distinct and easily distinguishable colors to pick from at any time.

2 starships and several hundred billion dollars and half a century in "Mars-rating" a reactor design.

I'm betting on the realistic variant.

>>12562544
I think musk mentioned how difficult from legal standpoint that is.

>>12562547
>literally just make up big numbers because you're scared of atoms

>>12562546
not even in the top 10 of non-existing best rockets

>>12562547
wonder if there will be a "solar ship" variant. Just packed to the fucking brim with solar panels and batteries and has everything needed to use the power and dispense it. Pretty cool that SS is big enough to act as a building.

>>12562553
>make up numbers.
There's a nuclear powerplant being built since the 80's next to me. This shit is slower than glaciers.

>>12562504

side boosters are for fags. Common core gets a pass tho

>>12562520
>Could SpaceX give Falcon Heavy a 5 meter wide upper stage?
Probably, but they won't. Not because they can't but because there's no reason to. Also it would not be transportable via road.
>How close is Falcon Heavy to BTFO’ing SLS?
Happened 2 years 11 months ago.

>>12562141
>If China's educational system is so superior, why the fuck did they send so many hundreds of their bright youth to my uni to crowd out everyone else in business and STEM courses?
because theyre bright enough to learn from all prestigious education systems in the world, you guys dont learn from theirs and that will be your undoing

>>12562553
>make up big numbers
Lets put it like this - design your martian reactor, produce it, and sell it at price comparable to the solar panels. Since fundamentally it will solve the need to deploy large fields of panels it will ultimately win out and SpaceX will take it.

I am 100% certain neither you nor somebody else will pull it off within the first half of this century, if at all.

>>12562517
A chopper and a ship to operate it, being rented for days with some sort of unique setup involved, is going to be pretty expensive too

I think they mixed those two dates up :^)

>>12562553
Nah dude, it's because the public is scared of atoms, which means the government is extremely stingy about letting private ventures work with atoms, which means for all the advantages of nuclear in theory, in practice is would be a development hell absolute flashing lights screaming nightmare, so they will instead send 1000 tons of solar panels and batteries.

I'm still not convinced by this mars thing. Feel like what's more likely to happen is we spread to orbit first. I'll bet 50 bux that a large-scale, likely industrial (permanent population 100+) orbital station proves a lot more practical and ends up coming before any serious planetary colonization effort.

>>12562566
ok chang

>>12562554
I agree, it was simply a dig at that guy lmao.

>>12562556
Generally, a single SS landing can put down about 1MW worth of power in terms of solar panels. You can get more with optimization instead of common off the shelf hardware.

Deploying it is hard. I'm voting for people with cybertrucks.

>>12562579
doesn't dust on mars stick to everything? How will they handle that?

>>12562582
nasa was worried about that with the pre rtg rovers. it turns out the wind clears it off pretty well

>>12562582
Tilt them so they don't build up dust. You are probably thinking of the very sticky moon dust.

>>12562535
Where is this 15 ton 650 kilowatt reactor now? Do any exist ? Does the highly enriched uranium or plutonium needed for it exist?
It’s never been about mass but about the cost... government doesn’t let people do nuclear anymore

>>12562582
Mars dust isn't so terrible, because there actually is an atmosphere and it all gets ground down finely. Moon dust is the really bad one.

This kills the Mars """colonization""" shill. Take off your popsci goggles.
