Satisfying the human desire for exploration and expansion

colonization is not related to exploration

its just an irl kerbal space program for elon nothing else imo

>What's the point of X ?
Literally nothing. There is no point to any of it, we came into existence by chance and the universe will end some day.
Legacy? Building an empire? Advancing our species? None of that matters, it'll be all gone one day with nothing to observe the ruins.

Or you could just stop being an edgy 16yo nihilist.

Wouldn't investing in a moonbase be exponentially more beneficial? We'd be able to mine resources and it's much closer. On top of that the lower gravity and lack of a real atmosphere would allow us to launch rockets much more easily.

>>9217590
colonization gives the infrastructure you require for exploration

How does colonizing inside the gravity well of mars help exploring

>>9217622
No way a mars colony could survive without earth

>>9217655
Mars has a lower gravity, so the well is not as bad
colonizing mars gives easy industrial access to it's moons, which can be mined to build the spaceport
that spaceport can be used as a stepping stone to the belt

>having a backup home planet rich in elemental resources
You might be retarded. Even though Dyson swarm will make planets obsolete, there is still a benefit to having colonies planetside

>>9217778
Pretty sure earth meets your requirements

>>9217782
>having a backup home planet rich in elemental resources
backup for what?

>>9217579
long term it could pay off
Mars is rich in iron and this could be an opportunity to develop the sorts of technologies needed for reliable space travel and colonization. The first steps are the hardest.

>>9217579
How sulf-sustaining could that colony be, really? I read somewhere that if all of Earth's electricity was generated by solar panels, than 1% of Earth's fresh water supplies would have to be used for the production/recycling of solar panels. The article was in the context of dimishing water ressources, and why going full solar may be a bad idea.

However wouldn't that mean that Mars colony was already doomed? There is no way you have that much water on Mars to produce solar panels en masse.

Also, basically the production of almost everything needs vast amounts of water. No water = no industry. No industry = no way to be self-sustaining.

>>9217793
Mars is not very good for space travel, since it has a pretty deep gravity well. Moon (or moons of mars) are way better

>>9217658

not an initial colony but in the future there is no reason why a space colony cannot be self sustaining

and we wont get to that point unless we try

>>9217579
Colony on Mars will literally never happen.

Where the icewater is, there are no other ressources. Where the other ressources are, there is no icewater, at least not in large enough quantities.

The distance of hundreds to thousands of kilometres between these ressources is not exactly trivial. It is literally what makes it impossible to ever colonize Mars.

To make the supply chains work you would need 10 or maybe 100s of thousands of people living on Mars. But you don't have the ressources locally to supply such a big population. Note that on Mars every single inhabitant has a WAY bigger energy demand than on earth, while at the same time producing energy is much more difficult.

>>9217783

>>9217809
You need energy to turn ice into water. So if the process of heating the ice to make it melt, and keep it warm so it doesn't freeze again, consumes more energy than the solar panel would produce, than the whole process is basically pointless.

>>9217838
Then better we invest in new technology instead of fruitless mars colony

Would it not be cheaper to take asteroids and colonize them for solid elemental resources in space? The moon itself has quite the gravity well.

humans need gravity, here is a new article from Scott Kelly about effects of no gravity

http://www.theage.com.au/good-weekend/astronaut-scott-kelly-on-the-devastating-effects-of-a-year-in-space-20170922-gyn9iw.html

humans also need a fat layer of radiation shielding


these two constraints rule out both living on Moon/Mars and living in tin can space stations


it is becoming increasingly clear that in order to colonize space a rotating space station with several meters thick walls is required, anything less than that and people are not going to survive more than a few years

>>9217847

you literally cant produce enough heat this way even with 100m2 big mirror if temperatures are -60-100°C.

>>9217967

you certainly can produce enough heat to melt a lot of water and then it is only a matter of insulating the habitat to keep it warm

you seem to think people are going to live outside in -60 degrees, but any habitat is going to be underground and will have only small heat losses to replenish

>>9217967
Ambient temps are irrelevant when you have the power of the sun. I have a solar box cooker and I've baked bread in it, outside in winter when temps were -40F/-40C below 0. It hurt to breath the raw air. Keep in mind that is winter sun. The square area I was reflecting/using was only 16sq feet/1.48sq meters. That's just some tempered glass, spray paints, and cardboard. It wasn't even my best solar box cooker.

I'm quite certain NASA or SpaceX or who ever, can very easily make larger reflectors and better devices than I can. Alas, that is the least of their problems.

>LMAO GREENHOUSE
Greenhouses aren't an option on Mars, they're not an option on the Moon, they're not an option on Mercury and a bunch of other objects. Realistically in most cases you'll look at living at least 10 feet underground (also evens out the temperatures which on planets with little to no atmosphere can vary by up to 80 K between day and night on Moon and Mars and by up to 250 K between day and night on Mercury) and growing your crops in finely tuned artificial light.

>>9217848
Reminder to take a few /g/ents on Mars.

>>9218082

>planet without noteworthy atmosphere
>tons of micrometeorites

Mars has enough atmosphere to burn micrometeorites

However you are correct that there is no point in greenhouses

Greenhouses for space colonies were proposed before modern led lighting was developed

nowadays grower leds are very efficient and it does not take much electricity to grow a lot of food

so there is no point in building fragile greenhouses exposed to radiation, just build a a cozy underground farm with densely stacked levels of hydro/aeroponics and you are good to go

I hope most people fuck off and go being stupid on Mars. If they don't go there with being somekind of cyborg they gonna wake up in some bad reality...

It is kind of hard to save a sinking ship when someone is poking holes in it. Going someplace else without someone poking holes in your shit is much easier, per se.

I really don't get this idea that nukes can exterminate the whole planet.

You'd need millions of them, because nuclear winter is a meme. Nuclear weapons don't actually dump that much ash into the atmosphere; they use airbursts, which lift barely any material. Further, humanity is pretty resilient, we could survive another ice age. So unless literally every square mile of earth's surface is covered by a nuclear fireball, humans will survive. There are simply too many of us, too spread out, and we're too ingenious.

Same issue with asteroids. There are a few big enough to kill everything, but we're tracking them and they're in very stable orbits nowhere near our own.

>>9218710
>Why are people so interesting on going to mars for fun? I mean it might be cool for a month but it'll get boring. Nobody goes to vacation on a desert.
I'm interested in it because I have muscular dystrophy and can't walk here on Earth. But I think I'll be able to in Mars's gravity. And even if I won't be able to walk, I'll be stronger than I am here.

Mount St. Helens wasn't even one of the big eruptions and it was like the power of 1,600 Hiroshima nuclear bombs. It was a "Class 5" eruption. The highest, a "class 8" eruption would be like everyone launching all their nukes at once. It is like 1000 times more powerful than Mount St. Helens. But, then those bombs wouldn't hold up to that either if the eruption is longer than a few seconds. An 8 hasn't happened in a very long long time, not in recorded history, but there have been tons of them in the past. We are a bit overdue for one.

>>9218794
A class 8 eruption is possibly a civilization ender, but Earth will still be a far nicer place to live than Mars.

>Exploration/colonisation: sentimental reasons that could have impact on the general psyche and perspective of humanity. For our future, becoming more of a united species is a good thing.
>Resources/base of operations: we can use it to harvest resources (mainly to fuel itself and other endeavours, not for Earth) and we can use it as a base to launch further missions.
>Scientific research: so many things to explore, on-planet and in-orbit, but mainly further exploring the effects of different levels of gravity.
I think that covers everything.

Human beings, silly. And I assume the organic resources and water they brought with them. Beyond that, people produce waste and flake off dead skin cells all the time and, obviously, die themselves. Tardigrades will consume anything organic or fluid, even cannibalizing if necessary.

While this is by all definitions a fruitless waste of time to even discuss, microorganisms could very well sustain themselves on Mars.

Mars colonialists would be housed, much like the earliest ancestors of humans, within caves, ideally >100m underground. There you have excellent shielding against all radiation, probably large quantities of iced or maybe even liquid water, other ressources, and you are deep enough in the ground that using geothermal energy is possible.

>>9219460

>Earth humanity will recover quicker and live lives that suck less for Mars being around to remain civilized past civilization ender disasters.

You dont know that. Civilization on Earth may collapse and then simply never recover. Having a modern civilization is an ANOMALY, not the norm. There is no reason why it should arise again. Having a sustainable civilization on a place other than Earth reduces our chances or extinction massively.

>>9219525

>ideally >100m underground

It only takes less than 5 meters to block all radiation

>>9219530
?
Are you implying the radiation on Mars would not kill you?

Also living in deep caves is more about the much warmer temperatures. The water ice might be liquid there or at least not so incredibely cold that it is hard as a rock. And you could potentially set up a geothermal power plant. The caves are also the most likely environment to find past or maybe even present life, so you would be going there anyways.

>>9219536
I think the low pressure unbreathable atmosphere would get you before the radiation and even the temperature does.

>>gives you no benefit

>>9220947
No they don't, they let sunlight in which turns into infrared heat which warms the air which is then blocked from escaping by the glass.

>>9217762
This
Planets, and more specifically the huge amounts of delta V and rocket efficiency compromises needed just to escape their surface, are a needless complication for an interplanetary civilization. There's more of every desirable resource than we could ever need just floating out there in asteroids.

stop living on planets

so we need cave, sq 1km of insulation wallpaper, shovel, liquid water, food from hydroponic garden

>>9217579
Expanding human existence from this rock.

Eventually the colony would be a full fledged country independent.

>>9217632
It actually takes more Delta V to land on the moon since you need to use your engines to land rather than using a parachute and aerobraking.

>>9220947
I know brainlets don't realize this, because the Mars looks red and not icy, but that place is much colder than Antarctica. Do you believe you could just set up a greenhouse in Antarctia and grow weed there? Hint: You can't.

>>9221761
because of polar nights?

>>9221767
No, because a greenhouse doesn't increase the temperature inside of it if the ambient nature is negative. Leave a car out in the summer, and it can get 40-70 degrees hotter, than the ambient temperature. Leave it out in the winter (during sunlight) and temperature will increase not at all.

>>9221717

There's plenty of reasons. Unless you're going to start memeing about terraforming. Please tell me how you make a Mars colony safely self sustaining?

>>9221800
Centrifuges for gravity maintenance, large eco-habitats for food/ living, other industry for whatever.

>>9221802
I'll give max ~1000 years for this experiement. Human civilization is based on the cumulative knowledge of resource use. We can use diamond tipped drills, but if everything goes to the shitter we can always revert and revert and revert until we're at the starting point which can't really fail. The relatively high urbanization rate of Rome wasn't feasible after the internal trade networks of the Empire were no more, but the society just "reverted" to a more agrarian one. There's relatively few things that can happen on earth that would make humans go extinct. Oxygen dissapearing because of some bacteria or something for example. This is very unlikely though. However, a situation that would destroy the preverbial oxygen of mars would be much more likely and more easily "achieved", than oxygen dissapearing on earth.

What happens when the post-earth Mars colony suffers some strife or catastrophy, but can't revert to anything because the planet itself does not produce the necessary things for survival? It seems to me that you're very idealistic about humans, but if you look at our history it becomes quite clear that human civilization can only truly survive on a planet that is earth or earth-like. The foundations of human civilization on what is to us a barren rock are too shaky.

>>9221774

>~1000 years for this experiment
First, I think contemporary ambition would be quite satisfied with that timeframe estimation.

Second, your saying that no matter how clever the settlers are, they will be prone to more hazards overall that will one day create some unsurvivable set of conditions.
Several hundred or a thousand years is a long time for more advanced technology to develop to mitigate that worry. Also the settlers could wind up having geographic
separation and the redundancy effects thereof for their future civilization so that no single hazard could effect everyone on the planet.

It is interesting that some use your argument to make the case for colonizing mars, that is as a back up plan for humans should something go wrong on earth.

Disproving this kind of fear of society is one of the benefits to expanded colonization. People will rise to the challenge. They'll do what they must. The society we set up on Mars will have fantastic founder effects due to the barrier to entry filtration. Seeing it work will teach us more about what could be done on earth, too.

useless and unsustainable

even if we did build retarded domes and terraform it it would eventually go back to being a desert shithole because no magnetosphere lol

Imagine that there was someone who lived a basically functional life, but who had never fit in anywhere they'd ever been.

we are doing that right now. you fucking millennials think tech improves itself out of nothing. things get better through need and failure

It is a scalar that has the units of speed. As used in this context, it is not the same as the physical change in velocity of the vehicle.

You didn't.

As someone that does lots of solar stuff in both winter and summer, I can safely say that greenhouses work in all temps. I don't think any of you know how a greenhouse even works.

In extreme gold climates, modern greenhouses are all insulated. They are double walled using either glass, polycarbonate, or plastic sheeting. For most greenhouses there's just an air gap as insulation. For colder weather that gap is filled with heated air. In even colder climates the gap is filled with soap bubbles; usually on a day-night cycle. The greenhouses are all heated with supplement heat. This can be from any normal heating source like electric or utility gas or it can be from biogas methane generation, compost/manure piles inside the greenhouse, heat from livestock, or extra solar heat collection outside the greenhouse's solar footprint which is pumped inside as hot air. Normally, a combination of these things are used to ensure redundancy. In addition to this, thermal mass is also used. These are normally black-painted 55-gallon drums of water, walls of masonry on the back side, and also high humidity in the air. Once the thermal mass is heated up, with the ambient heat of the greenhouse, cold snaps outside make less impact on temperature swings inside as the thermal mass gives up its stored heat when the temps start to drop.

Regardless, even a greenhouse that isn't supplemented with extra heat will be far warmer inside than the ambient temperatures outside. Even more so if it is well insulated and has lots of extra thermal mass.
