Damn, now my Chinese imported shit will take an extra week to get to me in the states.

>>9642854

Because Earth is full of annoying Humans

>>9642854

Because Mars would make us a multi-planet species, a reserve of humans if earth gets rektd but Mars is not> and if Mars base would allow us better access to the outer solar system, which is important because things are REALLY far apart in the outer solar system compared to the inner, if we want more space colonies and more scientific exploration of the solar system, a Mars base is a must.

I think reaching Mars is important for getting Humans interested in reaching for the stars again. Mars is the next step after the Moon. But we also need orbiting infrastructure for future space missions, and a moon base.

>>9642854
>we have
What do you mean by "we", Peasant?

>>9642854

1) "Earth is far to small and fragile a basket for humanity to continue keeping all its eggs."

2) There may be ecological downsides to filling the ocean, Sahara, Antarctica, Siberia and Canada with people. Even if there somehow are not, expect environmentalists to fight you tooth and nail.

That all said, Mars may not be the best choice. Planets may not be the best choice.

On the other hand, having our entire survival tied up with what happens to a single planet that at east some of our guys say is already under extreme stress, in a system full of dinosaur killers, dependent on the continued moderate behavior of a single at-least-somewhat-variable star is not the best long-term survival strategy.

>>9642854
>we

Go back.

>>9643152
>Mars is the next step after the Moon.

It's the next big headline-grabber, but I'm not convinced it's going to play much of a role in any of the things you talk about. I suspect orbital habitats, with Mars maybe as something to orbit and provide a source of working mass, and eventually asteroidal bases, will be the way we wind up going.

Don't get me wrong -- I'm all in for getting a toe on Mars, poke around, see what's what, and am very open to being wrong about the future utility of Mars as a place to live. We're in different sectors of the same side.

>>9643308

It probably comes down to when humans can construct spacecraft that can properly shield the crew from cosmic rays, and if Mars lower gravity doesn't destroy skeleton systems and pregnancies.

>>9643023
kek

>>9643308

And yeah, I'm also open to the idea of orbiting Habitats. Habitats over Mars would allow people to work on the planets surface, but live in space. I think all the planets should have habitats over them if we can manage it. outside of testing it out and perfecting the technology, I don't think we need them over earth itself.

Jupiter is probably the best place for one, I think, because of the moon with the giant underground ocean covered in ice, and the moon covered in fuel. It would be a great place for science and economic activity.

>>9643348
>underground ocean covered in ice
Europa, and is impossible, the radiation would smash you so hard you'd instantly change sex, be a tumblr poster and turned into a crispy human meal at the same time.

>and the moon covered in fuel
That's Titian, a moon of Saturn, and is actually a better candidate than Mars if it wasn't so far away.

As for Jupiter, Callisto is the best bet, it's the furthest moon out and has no radiation cooking issues for humans.

>>9643348
>I don't think we need them over earth itself.

LEO infrastructure is more important at this point. One step at a time.

>>9646768

>>9646841
What makes you think that?

>>9646850
>>9646821
If BFR performs and ends up $75 per kg to LEO, basically anyone will be able to do whatever the fuck they want anywhere in the solar system

>>9646867
That's my point, though. LEO infrastructure will facilitate colonization and colonization will be much more difficult and expensive without it already in place.

>>9646850
The fact that what he posted directly disproved your reply.

>>9646879
I said nothing about government and nothing about whether or not it was already being done. Only about priority. See>>9646875

>>9646875
At the end of the day the only thing that matters is can your infrastructure produce fuel and refuel a rocket. If not it is simply a unaffordable waste of delta v to match orbits. To produce fuel you pretty much need an ice asteroid, but absolutely no one will let you put a multi megaton rock orbiting earth. Fuck, china or some other nutjobs will probably have a good go at blowing it the fuck up if you tried.

>>9642854
black people should stay off /sci/

Why can't we do all of them?

>>9645026
What is it about then?

Because colonizing mars gives humanity the power to live on other fucking planets

are you dumb or something?

>>9643152
Mars doesn't have enough gravity to hold on to oxygen.

It will never happen.

If anything it will be a Venus cloud base or infrastructure built by robots on asteroids and your potential children won't even see that in their life times.

>>9642854
There are no savages on Mars to ruin everything.

>>9647547
Because we can do none of them.

>>9647855
Mars doesn't have enough gravity to hold on to oxygen permanently but if an earthlike atmosphere was introduced it would take upwards of two million years to drift away

>>9645909
>Because if a disaster occurs on Earth the h*mans wouldn't go extinct
I don't see why anyone tries to make this argument. Literally no one would give a shit about human extinction once everyone was extinct.

>>9647865
>but if an earthlike atmosphere was introduced

Yeah good luck with that.

>>9647865
A vessel which could use the Venusian atmosphere to sustain itself is more viable since we don't have to fulfill some completely unrealistic beyond megalomane thing like 'oh yeah just move a whole atmosphere worth of gas.'

Start up the core with some megalomane docter evil nuke drill too right? Yeah totally feasible.

>>9642854

>Thick clouds protect from solar wind

Also easy access to explore Venus' surface and future plans for potentially terraforming or making it more habitable.

>>9648155

no significant resources in Venus atmosphere makes it a very poor colonization target

>>9642872
FPBP

>>9648179
What do you mean by 'significant resources' exactly?

The conditions are the primary thing of interest when considering colonization, resources are not the problem, water and oxygen can be had from the atmosphere.

If we were talking mining or resource gathering, there is no reason that could not be done much more efficiently with unmanned craft.

>>9648274
a colony needs some form of export in order to pay for imports
a venus base will require a lot of fucking imports in the early years, and probably lots still when it's moderately developed

>>9648365
It needs to have actual viable survival and sustainability odds before you can even start fantasizing about considering economics you sci-fi series enamored gloid

>>9648378
Economics is what determines if the colony is built in the first place

>>9648382
Well bad news then Chaim, there is absolutely no resource that can not be had cheaper by simply getting it on earth.

Even the most ungodly inefficient energy devouring synthesis will be more easy than getting it out of space.

>>9648274

>If we were talking mining or resource gathering, there is no reason that could not be done much more efficiently with unmanned craft.

Done where? Surface of Venus? Even robotic mining operation would be destroyed by the temperature and pressure. Asteroids? Good luck dragging those resources across half the solar system.

Resources are much more important than conditions. Any space colony will inevitably have to be an artificial environment anyway. But with enough local resources and ability to utilize them, anything from Mars to asteroids can be colonized.

>>9648398

>Resources are much more important than conditions

No, not if you want humans to live there, tell it to the ISS.
If by resources you mean rocks and metals then no. Water, oxygen, heat and light in the atmosphere on Venus make it far more viable.

What would you even need resources for?

By the time we can actually have an independent artificial environment that can sustain itself by harvesting and processing its own resources sustainably wherein we can actually survive, sure, but we are not anywhere near that point.

We don't even have continuous thrusters.

In any case, you can completely forget about ever terraforming Mars, it simply doesn't have the mass nor protection from radiation nor heat. Maybe some iglo structures with a nuclear reactor could be built on the poles where water can be had.

>>9648428

>No, not if you want humans to live there, tell it to the ISS.

Main problem with ISS is lack of local resources, with absolutely everything needed to be launched from Earth. On the other hand, a space station next to a large asteroid would be a really good place for a colony. Lots of radiation shielding and material for construction and resupply.

>By the time we can actually have an independent artificial environment that can sustain itself by harvesting and processing its own resources sustainably wherein we can actually survive, sure, but we are not anywhere near that point.

The point is to get to this point. Otherwise it is not a colony, just a base dependent on regular resupply from Earth.

>>9648392
>>9648382
Part of economics is having people who can participate in economics. You can't do that if for some reason everyone on Earth is dead. That is but one of several reasons. I'll not tell you the rest, you'd not understand them.

>>9648398
>Done where? Surface of Venus? Even robotic mining operation would be destroyed by the temperature and pressure

Whilst this is a perfectly fine argument, remember that the probes we sent from Earth had to endure below zero for months then suddenly subject to those conditions, doesn't matter how strong or resilient you make a machine, that amount of thermal shock has a major toll on the machines structural strength.

If a "floating city" ever becomes advanced enough to build and maintain machines to explore the surface, they'll probably had significantly better odds going from a modest temperature of 20c to the surface rather than several below freezing.

Why does this question keep coming up? It's about a backup in case of a natural disaster on Earth which sets us back, not because we've 'used up' the Earth and need somewhere else, or because we 'need the resources' of Mars (retarded argument, we can't feasibly lug Mars resources back to Earth anyway).

>>9648683
because we need to spend money on the important things like subsidizing loans for my ethnic studies degree instead of wasting it on silly things like space.

How many big fucking rockets is Musk even thinking for Mars?

Wouldn't they need at least three before a fourth passenger one?

First one for the automated fuel/air/power. Second one for the habitat/rovers/power. Third for other equipment and food. Fourth one would have passengers, their personal belongings and more food. Also passenger one needs passenger rover in case the rocket lands too far from habitat.

>>9652301
I mention to passenger rocket landing off because it was a plot line in the nat geo Mars show which intermixes present day reality with a fictional realistic Mars mission. Musk even weighs in on the passenger rocket accidently landing too far from habitat.

>>9646579
>>9646760
Cognitive dissonance

You know it's real because it looks so fake.

>>9652315
Even if it lands a long way away, surely they could just send one dude out with a bunch of O2 tanks and drive a rover back from the camp right?

>>9647872
Either you can or you can't. f you can, it will hang around for a few million years after you stop maintaining it. If you can't, it doesn't matter if Mars can hold an atmosphere or not.
Ether way, "Mars can't hold oxygen" is not very relevant to anything.

>>9652680
My point was that the rocket they land with has to have the space for a rover, not that it can't be done.

The rocket itself should be able to sustain them long enough to get to the hab, but any rovers would have to be able to transport all personal and cargo from the rocket to the hab. Much more than a simple Moon rover. Also safer to bring two.

>>9642854
The bottom of the ocean is harder to build permanent habitation on than Mars. Everywhere else wouldn't produce enough of anything or spread out humanity enough to be worth the cost.

>>9653277
>My point was that the rocket they land with has to have the space for a rover, not that it can't be done.
that's literally very very very VERY little space. The apollo capsule included a clever rover design folded. The bfr has more than 100 times the volume of the apollo capsule, they could easily carry one rover for each astronaut and do a race to the camp site

>>9654849
>Everywhere else wouldn't produce enough of anything
You're not making a convincing case for colonizing Mars.

>>9655532
If you could establish a colony on Mars with 1,000 people with the means to grow their own food, generate their own water and power, smelt their own ore, lithograph their own circuits, etc., then your job is done. They can use what they have on site to build another colony, a generation later the people from those two colonies can build four colonies, etc.

Some day Earth blows up, they barely even notice

>>9655605
Until they run out of something a tiny settlement like that can't produce, that is.

>>9655633
Such as?

I take the RepRap approach: a perfect colony is one that can construct an identical replica of itself without outside input

>>9642854
It'll be easier to colonize mars than ocean floor. The rest have serious political ramifications that being first to mars does not have.

Medicine could be a problem, the colony's ability to synthesize neccesary substances would be very limited.

>>9655697
Pretty much every medicine is derived from a plant and processed with organic chemicals. A colony could do without the rest that need intensive specialised processing, might suck but wouldn't be immediate danger, especially since disease won't really exist on Mars.

>>9649161

>>9655732

>>9655732

>>9655736
Jovian moons would be 10/10 scenery place to live if you could avoid getting shitloads of radiation.

>>9655509
You seem to forget that the Apollo capsule had supplies and support for a short moon trip. A Mars trip is so long that most of the space would be used in equipment, food, supply and support equipment to keep the colonists alive for so long.

>>9655635
Is this a serious question?
We on Earth have access to resources from across the planet. Until Mars did the same they would always be reliant on Earth. Take rare earths for example. There are a lot of them and they are very important for electric motors, computers, radio equipment, etc.

Ultimately I don't think it worth the effort of trying to produce everything. They need to focus on stuff that is heavy and used a lot of, like concrete. Rare earths are used in small quantities and could be easily imported. Same with medicine.

>>9655748
You would be amazed how little food 100 people can eat with survival rations.

https://www.amazon.com/ER-Emergency-Ration-1B-Preparedness/dp/B008DEYC86

3 days emergency rations for 4.5g and 700cm3. Assume 100 people at a 90 day trip you get 13.5kg of food and 2.1m3 of space. That's laughably small, one guys suit alone will probably weigh like 50kg or something.

>>9655779
forgot to mention, would cost as per Amazon (I'm sure SpaceX will find it on the cheap) 18.8k for 100 people@90 days, so each passenger is paying like 180 bucks for food.

>>9656102

not if you are underground

solar radiation concentrated by Jupiter magnetic field can get to really massive doses, but it is still relatively low energy radiation when compared to galactic cosmic rays, and a meter or two of material should shield basically all of it

>>9655788
>>9655779
Survival rations are for emergencies. Not living and working people. They would get sick and die long term on rations.

>>9656429
Survival rations won't cut it for 90 days, no. However, remembering that a lot of the mass of food is just water, all that matters is that it is rehydratable, you can recycle water as much as you like. That greatly cuts down on mass and space required.

>>9656429

If you were in a ballon atmosphere you could be asleep when it gets punctured, have time to get up to an alarm, make yourself a coffe then go fix it. Since at that height the pressure would be the same inside than outside the air wouldnt mix it would slowly slowly leak out, also that atmosphere is survivable with a fucking breath mask and you could easily have a lot of tanks of replacement atmosphere, also the possibilitie of making more oxygen from the atmosphere too

You do realize those numbers take into account advances in women's education and prosperity, right? They didn't pull four billion out of their asses, if they were just extrapolating trends they'd say there'd be 10 billion

Or nooo

This. This is the demographic projection if current birth rates remain stable.

>>9658070

Worldwide, birth rate AREN'T remaining stable.

You're an idiot if you look at any graph that has a line to infinity and believe it had any bearing on the real world.

I was reading something the other day that said that placing a 2 Tesla magnet at a Lagrange point in front of Mars would block out a bunch of the solar radiation and allow Mars to build up atmospheric pressure a bit, and start the process towards warming it somewhat and making it more habitable for humans. Is this true? I'm pretty stupid so I also don't know how big a 2 Tesla magnet would be. I looked it up and apparently that's the same strength as a neodymium magnet. But how big would it need to be? And if this is feasible, why haven't we done it yet?

Sorry if these questions are dumb, but like I said, I am too. I just like browsing this board to see pictures of space cause I think it's cool

>>9658070
What the fuck makes you think Africa will keep that birth rate up? The more little niglets they keep shitting out, eventually the West is going to stop feeding them and they'll all die of AIDS and starvation like God intended.

>>9658220
IT'S NOT A LINE TO INFINITY

How fucking stupid are you, a decline in fertility is backed into the four billion projection

>>9658226

A lot of Africa is industrializing. Pop growth is part of that, same happened in Europe.

Greetings /sci/, 80's Lando here,

Except that Africans are almost entirely dependent on foreign aid for basic necessities like food and medicine. The West is very generous right now only because things are going well for us. That never lasts, and when people finally get sick of throwing their money into the black hole that is Africa, they'll have to fend for themselves. In which case they'll do what they do best: let their infrastructure fall into complete shambles, starve to death because they don't understand basic agriculture, deforest the entire continent because they don't understand forestry, further desolate their agriculture because they don't understand topsoil loss from deforestation, completely kill off elephants and shit for black market ivory trade, and completely exhaust the fish supplies like they have off the Horn of Africa because they can't understand the concept that if you take the young fish along with the old fish, there won't be a next generation.

Africans are just fully grown children. Whites have been out of power in South Africa for, what, only 20 years? And yet they've already skyrocketed their murder rate and are literally running out of water. If the West just up and walked away from Africa, they'd be eating each other and practicing black magic to cure AIDS within a decade. Oh, wait, they already do that now.

>>9658212
Where's yours r-tard?
despite the alarmist bullshit regarding Africa, the world as a whole has declining birth rates, and we're (grand total) past "peak child".
Aside from your /pol/ish concerns about how few future people while share your lily-white complexion, population growth is NOT a major issue.

>>9658262
but it is tho, even with declining birthrates

>>9658262
>half the people on Earth will be black And That's A Good Thing
Yeah thanks for making it clear I'm talking to an absolute cunt, goodnight

Get fucked, shitskin.

>>9658223
There aren't any people on Mars, so why would you bother. Also there is no hard data that a 2 tesla magnet could ever protect an entire planet. Better to focus on colony protection of solar radiation.

>>9658266
>Yeah thanks for making it clear I'm talking to an absolute cunt, goodnight
Sorry, I didn't realize this was the /pol/ containment thread.

>>9658267

So If I'm black, my opinion doesn't count?
I'm white BTW, just not a racist.

>>9658233
Industrial growth in Africa is almost solely due to Chinese working deals with African governments that would make the old colonial powers blush. An example is they will build a railroad in return for some mining rights, they ship a couple hundred Chinese peasants and some heavy machinery, smash it out in a few weeks then proceed to rape stacks of millions of natural materials.

>>9658262
You are a poor troll but at least you are right, population growth is not a major issue. Once the west stops funding Africa, mother nature will take it's obvious course with billions of people living with pretty much 0 sustainable agriculture.

>>9658304
>You are a poor troll
Not polling, just moderately drunk
>>9658304
>Once the west stops funding Africa,
If Bill Gates is right, declining infant mortality should lead to declining population growth.
Sure, he's a book-smart liberal, but he's also a remarkably pragmatic man.

>>9658312
Besides, the point of this thread has little to do with Africa's future.

>why live in a home when we have streets?

Sending "humans" into space is stupid, short sighted, and ultimately fruitless. We're from earth. We are adapted to earth. Surviving outside of earth is pointless.

What we need to be doing is genetically modifying humans into unique species capable of surviving in extreme habitats. I don't know how we expect to create self-sufficient ecosystem on foreign bodies if we don't expect to change our metabolic requirements. As long as a mole person is capable of carrying a thought and uploading it to a computer, who cares what their genes are like?

>>9646590

Not an argument.

Imagine being a colonist on mars and never seeing a blue sky or a warm sun or feeling the wind on your skin ever again.

It's a desire to start over without all of the scum that makes up most of the world.

>>9642854
I wanna live in a transparent dome at the bottom of the Mariana Trench where I can just be left alone, is that too much to ask for?

I assure you pressure is not the issue

>>9659459
Imagine being on Earth and always staying inside and playing on a computer.

>>9659876
I was referring to the hundreds of atmospheres of pressure at the bottom of the ocean.

>>9659459

This is why you need to roof over Valles Marineris. You can use the pressure to balance the weight of the roof. It's big enough that you'll get a bit of a breeze at sunset.

Seriously though, all the ideas of gigantic O'Neil cylinders are that much easier to build on Mars. You just need a big ass inflatable dome, and you'll get a little bit of weather which you can artificially amplify.
