>Possible hop in a week or so
Will this be a 20 kilometer hop?
>>12032936
On the 28th of August TSLA will do a 5 to 1 stock split. For example if the price is $2,103.45 a share before the split it would become 5 $420.69 shares. The total value is the same only the number of shares changed.

>>12032979
No, it'll be a 150m hop to smooth out some hiccups during sn5 hop

Why does starship have to do a bellyflop, what's wrong with landing like a falcon 9?

>>12032979
Iirc the 20km hop will be done by SN8, since it will have more engines and all of its control surfaces. This hop will be the testing of either SN5 or 6 whichever one didn't hop.

>>12032989
More contact area with the atmosphere to slow it down

>>12032989
I think the bellyflop is to use the heat tiles facing the ground so they absorb heat instead of the raptors. Along with having more control of descent using the control surfaces.

>>12032867
As interesting as that trilogy is, it's not really a realistic terraforming.
Then again, you'd need immortal protagonist and to focus a lot more on the infrastructure in space.

>>12032989
Because F9 is slim and light whereas Starship is a chonky motherfucker. It's a matter of not spending half your tankage on slowing down your speed before you have to do your final landing burn.
So you use aerodynamic drag to slow it down instead.

>>12032989
Because SS will be coming in from orbital velocity, F9 1st stage has much less velocity to lose.

>>12032889
full me. I could have put in 32,000 when it was 300 something a few months ago. I could sell right now and buy a house.

So I've been thinking recently and is it just me or is Starship the perfect companion craft for a rotating skyhook? If attachment points could be built onto them, it could really turn Starship into a theoretical SSTO to a full SSTO. Probably not for general usage, but if you could remove the need for a super heavy to launch a tanker Starhsip maybe it could improve margins while reducing wear and tear on Superheavies.

It might make sense if the wear and tear on 30ish raptors is more expensive than the wear and tear on 3 raptors that have to fly four times as much.

>>12033054
Not for the tankers. You want the Superheavy to get it up. So most of the propellant is saved for transfer.

>>12033060
PRobably that is correct, but how I'm thinking is that maybe the fact you can only bring up 1/4 the propellent would be offset by only having 1/10th the engines of a superheavy so not having as much money get sucked away by wear and tear to them. I guess the variable that would make this viable or unvailbe is weather the total wear and tear on a single starship going up 4 times as much costs more than the wear and tear on a superheavy, if the superheavy costs more then I could see it being useful, if the starship going up 4 times as much costs more then its not viable.

>>12033129
Who's expecting Biden to win?

>>12033141
He narrowly won the last one, and it seems much more likely that Trump has lost supporters since 2016 rather than gained them. Given the fact that Biden is a lot less easy to hate than Clinton, I think you'll see more moderates going blue in a hope to return to normalcy.

People are talking about sci fi books in the other thread and I want to bring the discussion over here.

Q:What are some good space books? I have been reading the Expanse stuff but it gets pretty gay. Can be either fiction or nonfiction.

A:The Culture by Iain M. Banks. Those are the books that Elon read and inspired him to name the droneships "Of Course I Still Love You" and "Just Read The Instructions" (those are names of ships in the second book)
The series is hard sci-fi, very advances but realistic and grounded in real physics. They're complex with multiple protagonists, timelines and flashbacks, and neat politics of a post-scarcity civilisation,
Start with Consider Phlebas and read then in publication order.

Best part is that it curbstomps almost any other scifi. Star Wars and Star Trek are like cavemen compared to the Culture.
>"You might call them soft, because they’re very reluctant to kill, and they might agree with you, but they’re soft the way the ocean is soft, and, well; ask any sea captain how harmless and puny the ocean can be."

>>12033142
>That 90 degree flip up right before landing

>>12033151
I completely disagree honestly. If the riots hadn't happened, I think you'd be right, but considering a large portion of the left has actually supported the riots I'd bet that has pissed off a lot of independents.

>>12033147
(((The Party)))

>>12033052
The Xeelee are one of the few sci fi civs thats more advanced than the Culture. They have time travel and reality bending pseudo-magic which the Culture does not.

>>12033142
this one is more accurate
https://twitter.com/C_Bass3d/status/1296089816220807168

>>12033151
Yeah, Anon need to remember Donnie margin of victory was 80k people in Wisconsin, Pennsylvania, and Michigan. Now hes not facing Hillary Clinton so that already is like 50,000 voters he inst guaranteed. The margins arent there for donnie to win in most cases.

>>12033177
you keep forgetting about the BLM riots. i'm sure that has pissed off a lot of independents

>>12033177
Not that anon, but things in MI are a bit different after the governor pissed us all off, I would be pretty surprised if we swung wildly blue this year. Can't speak too much about the mitten but the Yoop was pretty red last time around and I expect that to increase.

>>12033156
For real. I’m pretty sure Elon will distribute standard issue brown trousers for the landing uniform.

>>12033165
FUCK SPACEBEETLES AND FUCK THEIR STUPID RING

>>12033195
>>12033199
I'm more dubious about the amount of people driving away by BLM stuff, the worst of the damage would've happened in urban cores who vote Blue no matter what. But even that aside the two fundamental forces that aren't in doanlds favor is unemployment and dead grannies both of which he has in abundance. Whether those are his fault or not, those are the forces that drive the politically apathetic to angrily vote against whoever is in charge. The pandemic and resulting damage are gonna sink him.

>>12033161
>the riots
Yeah, that's kind of the toss up in this whole situation. If Trump was actually successfully addressing the riots and controlling the media narrative, you'd likely be right. It'd be the '68 DNC riots all over again and the law and order candidate would win. However, with the way it stands now, I believe Trump's come out of this looking like he's completely unable to handle the crisis, with every move he makes, whether it be aggressive or passive, being heavily criticized.

It's not a good sign when his campaign commercials showing "what America will look like under Biden" are using footage of rioting that's gone largely unchecked under his presidency.

>>12033124
How do those data cables not melt or corrupt data in transit?

>>12033223
It was always a lose-lose scenario
>send in nat. guard, crack down hard
>"omg literal facist!"
>hands-off approach lets states do whatever the fuck they want
>"omg why isn't he doing more?!"
Which isn't to discount your valid criticism, I'm just not sure what if any winning move there was to take.

What will the first bases on Mars look like realistically? I just can’t believe the marketing images of the domes. They’ll get covered in dust and the occupants drenched in radiation.

Some people are saying 99% of them will be underground with just a tiny ground level presence, how realistic is that?

>>12033221
> unemployment and dead grannies both of which he has in abundance
a lot of that has been democrat governors in states like PA, NY, NJ, etc etc sending covid infected people into nursing homes

>>12033257
It's quite realistic, most of what you'll see outside is fields of solar panels early, and fields of radiators later.

>>12033252
Yeah, I think the only way for Trump to come out of this ahead was to commit to one or the other. If he went full "fascist" and put the riots to a stop, he'd piss off people who weren't voting for him anyway but shore up his base along with moderates that just want stability. If he took the hands-off approach, he'd likely disappoint his base (but not enough to get them to vote for Biden), while simultaneously avoiding some of the heavy criticism he's been getting from moderates and the left. By oscillating between both, he ends up pissing off both sides and looking like he's got no idea how to handle the issue.

>>12033223
https://mobile.twitter.com/KittyLists/status/1296628991445491712\
i don't think these riots are really just affecting urban cores. and it doesn't matter if they only affect urban cores anyway, as those votes still affect which way the state goes

>>12033257
It is all marketing. Musk and the engineers at SpaceX are smart people. They know without a shadow of a doubt surface habitation like we have here is a total impossibility. Living on mars will be like living on the bottom of the ocean. The colonists will live in steel boxes with no natural light and no view of nature. So they have to lie in the marketing, if they showed how bleak and suicide inducing mars will be, nobody would be excited for it.

On the plus side, I was pleasantly surprised to be wrong on him just letting the CHAZ/CHOP fester for a while, I'd wanted it cleaned up asap but in the end it proved more fun to watch it burn itself out, plus made the mayor there look like an idiot for waiting until rioters came for her to do anything about it.
Other anons probably don't appreciate all the politics itt though, so let's get back on-topic. That animation earlier in the thread of SN8 doing the bellyflop, is it confirmed or just assumed it'll be doing the 20km hop? SN6 is the one on the pad now and that's supposed to what, do another 150m hop or several? Wonder what the point of hopping SN5 and SN6 the same height/distance is, seems redundant if that's all SN6 is for.

>>12032989
Bellyflopping Starship has ~6x the drag area but the same mass, meaning it can slow down higher up, meaning it gets less reentry heating (lower peak temperatures and lower total thermal flux load). Bellyflopping also gives Starship a decent ability to control its point of landing on the ground, important if you're aiming for a pad nearby to some important infrastructure.

>>12033257

Oh dare you doubt our immortal leader? Of course we will have gigantic jungle dome made from local ore a month after the first landing.
Its just hardwork from our Ayn Rand pioneer who free from red tape will usher the new mankind.
Give it two year and Mars declare its independence, then on the 4th year it will have its fleet of warship and liberate Earth.

>>12033319

You are right.
As long as you pay for your really fancy euthanasia yourself I've got no problem with it. We get to build rocket and get rid of you, you die on Mars because you clearly aren't that smart. Everyone is happy.

>>12033327
Would it be possible to build something like the geofront from NGE? Having a lake and forest underground would be fucking baller and would do wonders for the sanity of colonists.

>>12033333
I wonder if you could make whatever binding agent you need in-situ as well, proonting memes aside it's not as if bricks aren't still a viable construction material and if you can make them on-the-spot that's pretty good. I bet a brick building could be filled with some weaker inflatable hab with a lock at the entrance, reinforced walls and radiation protection all in one.

>>12033343
I've been thinking the same thing ever since seeing Zion in the second Matrix film. Just because you're underground doesn't mean you have to feel claustrophobic.

>>12033343
no clue what NGE is, I don't watch anime (i'm assuming that is what it is). But yes, pressurizing a lava tube and having a sort of artificial ceiling that simulates the sky (but it'd simulate a martian sky and a martian night sky of course) along with forests, lakes, rivers, and even hills should eventually be possible.

>>12033349

>>12033321
>Actually 250000 thousand, 500k is for round-trip.
All trips to Mars are round-trips because the trip back is free, according to Elon.
500k Mars ticket price was going to be for the ITS rocket (12 meter carbon composite space whale), 250k is for Starship.

>>12033337
How do you mean? Are the cables chilled?

>>12033356
am i the only person here who likes starship design over its design

Hey guys, I'm first year mech eng fag and I was wondering if you could provide some good material for learning to create my own rocket. Something fun I could design on CAD and then 3D print or/and use water jet and some other machinery to get it all together.

>>12033344
Bricks are fine, it's 3D printing which is the meme. Hell, we could make bricks using salty water to make mud then expose the bricks to the ambient pressure on Mars; the water would rapidly evaporate and leave the salt behind as a weak binder, weak but good enough for stacking simply vaulted radiation shielding structures.

>>12033353
Mars One: Where your bunk is also your grave
>>12033350
Different anon but yeah, Evangelion features a massive spherical void inside the crust under Tokyo 3, colonized and turned into a self-contained command center for a shady government group. Hilariously, the skyscrapers above are built to retract down into the geofront (the void) in the event of an emergency to protect them, which looks both ridiculous and cool.

>>12033450
really? not surprised, /x/ are eternal contrarians

>>12033455
Yeah, they are saying shit like "now that UFOs are real, they don't belong on /x/".

Why are we not sending rovers to the moons of Jupiter like Europa? Seriously, why are we wasting time on mars and the moon.

>>12033462
so according to them, /x/ has to be for shit that is fake? thats hilarious. they should rename /x/ to /f/ or /fantasy/

>>12033462
Outstanding.

>>12033383
We haven't even gotten to the juicy parts of traditional rocketry. We've been using basically the same fucking design for like 70 years.

>>12033466
Because the whole reason we're sending rovers to places is mostly to prepare for future human missions, and future human missions to the moon and mars will come much sooner then missions to Europa. On the other hand, a drone called Dragonfly is being sent to Titan in 2026 and will arrive in the early 2030s. The mission plans for around an 80 kilometer journey in total, but considering we've had Mars rovers that have traveled for 14 years when they were meant to travel for several months, who knows what will happen with Dragonfly.

So I think Elon said building the production line is 1000x as hard as building the prototype or something. But presumably a big part of the design of Starship has been ensuring it can be mass produced, and then you need someone to build the production line. So what kind of person does that job? 'Manufacturing Engineer'? 'Production Engineer'? I'm curious about this anons.

>>12033473
>>12033474
Some of them also think the UFO information over the past few years is an elaborate CIA psyop to create a world government,

>>12033392
It might be close since the Chinese plan to start with a robotic outpost then upgrade it to a manned base. The first robotic elements are supposed to land within the next five years.

>>12033473
>has to be for shit that is fake
Or at least in the 'unproven/paranormal' category I'd presume. I haven't been there much since it was wall-to-wall creepypasta though, I haven't known the board in years.
>>12033488
I don't think the CIA are competent enough to pull off a fake-disclosure, there's a lot more you could fuck up compared to just overthrowing some South American president.

>>12033480
Nevermind, they plan to fly the drone around 175 kilometers

>>12033501
They also never explain how exactly a CIA psyop would force Russia, China, EU, and U.S. to become one government.

>>12033505
Yeah I think those nations all want to be one world governments, just not with each other and each wanting to be in charge of it. Smaller competing conspiracies, rather than one improbably-big and all-encompassing one, just seems way more likely.

>>12033380

Yawn, it's all so fucking tiresome.

Why are chinks and mutts so fucking stupid???? If I was in charge of the United States I would send 3 manned rockets to the other side of the moon to mine Helium-3

Helium-3 is extremely expensive and extremely useful, in no way mining Helium-3 on the moon can get you losses.

With Helium-3 I would power Fusion rockets to take over the rest of the solar system, but it seems humans have lost the spirit of conquering?

There's a "small" issue with needing to sift through 150 million tons of lunar soil to get one ton of He3. Not entirely feasible. A better use for a lunar base would be rocket and chemical propellant manufacturing plant. That way, missions beyond Earth's sphere of influence won't require an absurd number of rocket launches from the Earth's surface to prepare.

>This, uh, scares... the Musk Man

>>12033778
how absolutely embarrassing

>>12033765
>>12033770
>>12033773
Interesting designs, although a description for the source of the symbolism would be appreciated.

There's also an issue about Martian flags versus Earth flags in terms of shape. The average dynamic pressure due to winds on Earth is about 20 times higher than on Mars. This would mean that there would be less wind force to pull on a waving flag on Mars. As a result of this, I suspect that Martian flags may have a smaller aspect ratio than Earth flags so that such flags can be waving at full display in the weaker Martian wind.

It would compete by being able to deliver a larger payload, able to loiter with full propellant tanks for extended periods of time, and not being tied to the SLS.

Well, >>12033773 is meant to represent Mars (the red circle, obviously) being brought into the domain (or light) of humanity out of the darkness of the void. For the other two, I was experimenting with abstracting Mars itself as a stripe, but I couldn't work out how to incorporate the white around it without awkwardly invoking the various flags of the UK.
The four-point stars are Phobos and Deimos, clearly, and will play a significant role in developing the planet, so I felt they deserved recognition.

>>12033773
Don't like em that much. First one looks like Deadpool is staring it you.
I don't like diagonal motives on flags in general, but I suppose second one is still the most decent one.
Third one looks like you tried to display the Japanese Flag in the wrong resolution and ended up with black bars top and bottom.

How is that game? How much does it break from reality to have a playable game? Missiles or lasers?

>How is that game?
Extremely autistic.
>How much does it break from reality to be playable?
Lasers aren't the default primary weapon, you can make rocket bells and gun barrels out of highly improbably materials, some elements don't behave quite like they should. Mostly down to simulation not being perfect, more than compromises for gameplay.
The solar system isn't one big map you can move around in.
>Missiles or lasers?
Missiles work fine for the AI enemies you'll be up against in most situations, once you learn how to make them, lasers are the ultimate endgame for weapons though, other weapons like ultra high velocity guns can match them for lethality, but not for mass or cost.

>>12034368
That's not what I said you mong.

>>12034381
good
not a whole lot, the main limitations are just in the accuracy of material properties which can be kinda sketchy because of lack of data reliable data for some things and assumes all materials are isotropic and doesn't take into account chemical reactivity or anything like that, plus it only includes technologies where there is enough information known to make a full model of them so for example you can make boosted fission nukes but not proper fusion devices because the details of them are still classified
both can be extremely powerful, but there's no clear winner in a head to head matchup with optimized designs because you run into the limits of the simulation like FPS issues trying to deploy a billion missiles to close on a laser before it can zap all of them and lasers being limited to a maximum 10000km engagement range

>>12034247
I'm no graphic designer, but I tried to make a decent high-res version of this in gimp

>>12034425
Define thick? Most of my ships have never had more than a couple mm total of rigid armor, I would usually go with an ballistic fabric of some kind on the inside, one or two rigid shock plates of boron fiber or one of the stronger metals, padding made of aerogels inbetween layers and an external shell of polyethylene plastic, which due to simulation memes is one of the best anti-laser coatings. Doesn't do much against player lasers, but then again neither will ten meters of solid steel, it's more than enough to protect my ships from most anything the AI can throw at them.
Here's some modded in fusion weapons, normal nukes are a bit of a crapshoot since the dev can't exactly model them realistically, they tend to be far weaker than they could be in real life.

Here's some stock AI ships getting melted down into hollow aluminum shells by a cluster of small fusion torpedoes exploding in the midst of their formation.

>>12034479
>Define thick?
See >>12034449. I guess I misspoke. It's not thick, but a cone with that angle and wide enough to cover a ship would be ridiculously long.

>Doesn't do much against player lasers
Why?

>Here's some stock AI ships getting melted down into hollow aluminum shells by a cluster of small fusion torpedoes exploding in the midst of their formation.
Seems like nukes would be the "meta" weapon.

>>12034491
About 5 degrees off axis is acceptable. 10 degrees is pushing it. Only use more if you absolutely have to.

>>12034507
What gender is this?

>>12034498
Very long cones are pretty common in CoaD, embrace cone.
>Why doesn't armor do much for player lasers?
Because lasers are stupidly powerful when you start pumping a couple hundred megawatts of power into them, and can strike out to enormous distances if you build them with giant hubble sized focusing optics. An NUV monster with a 5m wide focusing optic powered by what would normally be considered a commercial city-sustaining nuclear reactor can cut through steel only marginally slower than it cuts through complete void.
In real life serious issues in manufacturing all the necessary parts would probably preclude such an "easy" superweapon, but CoaD has no such restraints. A player can easily make a ship which is essentially a flying reactor bristling with laser emitters so powerful they can cut through any thickness of material almost instantly.
>Seems like Nukes would be "meta"
They would be if lasers didn't exist.

>>12034498
>Why?
because you can make absolutely meme death star lasers that would happily melt your ship and the asteroid its hiding behind

>Seems like nukes would be the "meta" weapon.
nukes are decent, but unless you can get direct hits you need really fucking big nukes to do more than just toast their skin since all you have is the flash of light to transfer energy
minimum size nukes are super useful though, either just as ammunition for your guns or using the CHAD move of putting them behind fragmentation disks or heavy slugs in missile warheads to shotgun or just blast rhough both sides of the armor depending what detonation distance you use

>>12034507

>>12034513
I feel like in real life lasers would be a bit self-limiting in their ability to penetrate materials because at some point you're flash heating those materials so fast that they form a plasma that is opaque to light, meaning a thin layer of steel gets vaporized and turned to plasma, and the plasma absorbs the rest of the laser pulse energy.

>players making huge powerful emitters
Seems like a missile with a bucket of sand would be a solid counter to that.

>>12034521
The plasma is beneficial when you can effectively time your laser's pulses so that each pulse hits once the plasma has dissipated. This allows the laser to continuously deliver it's energy to the target and the plasma acts as a drill, continuously pushing aside some material and weakening other material by shock-heating it.
Your laser is also obviously limited by it's own internal component's capacity to be heated to extraordinary temperatures.

>>12034530
>A missile with a bucket of sand.
Yes, this can be done, assuming your computer is powerful enough that keeping track of all those little physical models and their properties, locations, and interaction with the ship they hit, without bursting into flames and killing you with cheap Chinese GPU shrapnel.

>>12034521
you can deal with that to a large extent by just using a pulsed laser so that the plasma disappates between each pulse, and if you're using a powerful enough laser it's just gonna fucking burn through anyway

>>12034554
Why would that not be possible?

>>12034551
Well, the game does allow you to do "shotgun" type missiles, because see the "bullets" modeled in the game are different from physics objects like ships. They're much more processor friendly and the game has "warhead" modules which you can customize (size, dimensions, type of explosive, type of fragment material) that instead of producing a cloud of physics objects your rig has to keep track of, just generates a spray of "bullet" type projectiles.
You can also put solid objects infront of pure explosives, or nuclear warheads, and create similar shotgun sprays of shrapnel. Casaba Howtizer style nuclear shotgun missiles used to be really effective. I haven't played recently to test what still works though.

>he Fujiwhara effect, sometimes referred to as the Fujiwara effect, Fujiw(h)ara interaction or binary interaction, is a phenomenon that occurs when two nearby cyclonic vortices orbit each other and close the distance between the circulations of their corresponding low-pressure areas. The effect is named after Sakuhei Fujiwhara, the Japanese meteorologist who initially described the effect. Binary interaction of smaller circulations can cause the development of a larger cyclone, or cause two cyclones to merge into one.

Anyone hyped for the type of civilization that will develop on Mars? It'll be at least for the first few decades the first civilization where each citizen is 130+ IQ. Everyone will have to have a useful job to society, engineer, doctor, botanist, chemist, etc. It will be a society of extremely hardy and practical pioneers who will have to master a wilderness and frontier harsher than any humans have ever had to deal with. With no micromanagement from Earth being really feasible, they will have to self govern and master themselves. So many forms of government may be perfectly feasible when the body politic is comprised of such individuals, and depending on the developmental circumstances I could see direct democracy, technocracy, or fascism arise. There will be no place for leeches, grifters, or bums for at least the first few decades if not century. Society cannot function with them and they'll get spaced if they don't shape up. Everyone will have to earn their keep. The people will also be united in an almost spiritual common purpose to survive another day, of making the rock habitable, and eventually terraforming the planet. Eventually Mars will have the best universities, scientists, engineers, shipwrights, etc while Earth will stagnate into poverty on one hand and decadence on the other. I cannot wait for Mars to declare independence and nuke any Earth ships that try to stop them. It will be a revitalization of the soul of the human race, the humans who conquer the stars will come from Mars and the torch of civilization will burn on forever if we can get off this shithole before it deteriorates.

Lava tubes are cool. I'm sure you could redirect the sunlight with mirrors or something so you wouldnt get irradiated. Plus you wouldnt need heavy machinery and explosives to dig underground since nature did most of the work for you. I dont think you could pressurize one with all the faults and cracks running through them especially given the age the ones on mars would be (likely millions of years old). An inflatable structure inside would work. I'm sure they could be much much larger on Mars due to the lower gravity than the ones on earth unless theres some limiting factor from the flow dynamics.

>In 1970, Apollo 13 was launched and had to be re-routed because of an explosion on the service module. This failure could have been avoided if safety measures such as a backup oxygen tank were in place - but since NASA didn't want to take any risks they didn't include it, which is why there was no way for the crew to survive this incident; however at least their lives were not lost due to bureaucratic incompetence like Komarov's death during a Soviet launch.

>The Space Shuttle was the next big project for NASA, but it was not without its failures. Challenger exploded on liftoff in 1986 due to a faulty O-ring - but this could have been avoided had safety measures such as a backup solid rocket booster been included by NASA. The Columbia disaster in 2003 is more complex since there were multiple contributing factors; however I would say that the most important factor was that space shuttles are expensive and they can only be used once - so therefore they should be kept grounded until further notice, or at least retrofitted with safer heat shields.

>Now we must ask ourselves: What is the purpose of NASA? I would say that its main goal should be to increase knowledge, not to go into space. But if they are forced to do so due to budget cuts then they should at least make sure that their shuttles are safe enough for re-entry.

Would america be better off not persuing space flight?
Spaceflight is a misleading term. There's no atmosphere up there to speak of, so it's not really flying in any way that humans would recognize. You can't even fall off the edge and die! It might be better if we thought of spaceflight as being about getting into orbit around a planet instead - because this is what they are actually doing.
I can't see any reason why we would want to put humans in orbit around a planet. It seems like an idiotic thing to do with human lives and money, especially when you have no idea what they might find there. Humans are curious animals by nature, but I think this curiosity should be limited - it's better not to know some things.

>>12034956
>tfw you will never live to see the Martian state gun down refugees welcome activists who support Terran immigrants to resettle in Musk City

>>12034958
I would much rather see us spend our money and effort on building a better future for ourselves here on Earth instead. I do not mean to be selfish, but if we were to take all of the people who are currently working in spaceflight and put them to work improving life down here, then they would have more time with their friends and family - which is surely more worthwhile than spending all your time floating above the planet.
If we were to put all of the money that is currently being spent on spaceflight into improving Earth, then it would be possible for everyone to have a much better life. There would be no need for anyone to die in poverty or live without modern medicine. We could make ourselves stronger and faster and smarter than ever before.
If we can extend life to around 1000 years then that is plenty of time for everything to be made perfect. This way, there would be no need to waste all your time working or living in fear - you could have as much fun as possible! And it's not just humans who would benefit from this. The planet itself would become a greener and more beautiful place.
If we were to spend all that money up in space instead then it would be a pointless waste - what's the point of putting humans into orbit around a planet when you can't go anywhere or do anything interesting? I'll grant humanity this much: they've been very creative about finding ways to kill each other. But that's not enough for me.

Theoretically, I would love to see humanity explore the stars. It is a worthy goal for mankind in my opinion and there are many benefits that could come from such an endeavor. However, I am not sure if we as a species are ready for it. The reason why is that our society has the potential to collapse at any moment.
Humanity is a race of warring tribes. We have been so for thousands of years. It was not always this way. Humanity was once united under one government, but that changed almost 200 years ago.
We as a species have been at war ever since. Until we settle our differences and come together, I don't think that we are ready to take on the challenge of exploring space. I think that we should be working on building a better society here on Earth. That is the first step to becoming worthy of the stars.

One thing that worries me about space exploration is how humanity will react when we encounter non-human life.

>>12032848
I find that space travel does not deserve government funding. Here is my argument:
First of all, space travel is not actually a necessity. It would be nice to go into space because it would help the exploration and education of our species but that isn't reason enough for governments to spend money on such an expensive project. We have a lot of issues in our own country that need to be addressed. The government should not put money into something as expensive and unbeneficial as space travel when they could use it more wisely elsewhere. Secondly, space travel does not help our society in any way or form. It is something that could be done without and the money can be put to a better use. People will argue that the space program is beneficial to our society because it helps us study science and learn more about the universe. Yes, we could use this for such a thing but there are other ways of doing so. We don't have to send people into space to do these things. We have satellites in space that can do this for us. We are also able to send robots into space as well.

>>12034973
i agree

>>12034973
Failure to become a multiplanetary and ultimately multistellar species will result in the extinction of our species. One of the primary tasks of government is to protect it's people.

Here's your fucking Mars flag.

Is the hurricane going to hit boca?

>>12034884
Well well we’ll...

>>12034996
Girl Mouth (Boca Chica) is right on the Mexican border so no. At worst they'll get the fringes of a cat 1.

>>12034996
no

>>12034996
They might still get enough wind and rain to put things on hold for a day or two but it shouldn't be too much of a problem.

>>12035018
>Note: The cone contains the probable path of the storm center but does not show the size of the storm.
If the center tracks to the southern portion of the uncertain area Boca could still get hit by the outer parts of the storm. It might track north and completely miss though, and even if it does hit Boca it probably won't be anything too damaging.

>>12035033
If the storm strengthens (it will), it will trend north.

>>12035036
The other hurricane will block it's path.

>>12035041
The other storm will be stronger and will go north as well.

NLS when bros?

>>12035086
>A series of launch vehicles was proposed, based around the proposed Space Transportation Main Engine (STME) liquid-fuel rocket engine. The STME was to be a simplified, expendable version of the Space Shuttle main engine (SSME).[3][4] The NLS-1 was the largest of three proposed vehicles and would have used a modified Space Shuttle external tank for its core stage. The tank would have fed liquid oxygen and liquid hydrogen to four STMEs attached to the bottom of the tank. A payload or second stage would have fit atop the core stage, and two detachable Space Shuttle Solid Rocket Boosters would have been mounted on the sides of the core stage as on the Shuttle.[3] Period illustrations suggest that much larger rockets than NLS-1 were contemplated, using multiples of the NLS-1 core stage.[5][6]
WHEN?

>>12035111
Last thing the world needs is more foam fireball launchers that will never be human rated.

>>12035120
but think about the cost savings, we can just reuse existing parts instead of having to design a whole new system

>>12035086
Isn't that basically the RS-68 and the Delta IV?

Why do we treat expendable rockets as a bad thing but it's suddenly okay when it comes to food? How many fucking billions of dollars are we wasting every year on painstakingly producing and transporting and preparing food only to throw it away after a single use? Why isn't there any research being done on reusable food?

>>12035135

Modified shuttle tank and multiple throwaway simplified RS-25. Would still be a foam fireball.

why does putting multiple identical engines on something give you less dv than just one engine
is it just because of the extra weight

>>12035140
Because food is vital to survival and gets subsidized to keep farmers in business even if we don't need the food.

>>12035155
Yes, multiple engines adds mass.

I don't get this reusable rockets meme.

>>12035155
Shitty TWR will do that.

>>12035155
It is.
Engine give you extra acceleration but all it mean is that you'll use your fuel faster and use it to push the mass of extra engine.

Of course there's more nuance when it come to launching out of planet. You need TWR above 1 or you can't take of, and if you gain altitude too slowly you are wasting fuel staying up.

To move away from a planet and reach another you don't need a high TWR, you could accelerate so slowly you don't notice it and still reach your destination. But having such a slow acceleration could cripple you in other way.

Terraforming Mars, even if physically possible which I think it probably is, will be politically nonviable.

>Convincing tens/hundreds of millions/billions of people to evacuate their homes, pay for space habitats, watch everything on the surface get absolutely fucked for at least a century or so before there is a tiny thin band of habitable land because the verticality of Mars means you cannot achieve the desired atmospheric pressure on more than a small amount of the planet.
