Recently, I watched in this order, PBS's documentary on Arctic Sinkholes, Interstellar (2014), and The Martian (2015)
Sinkholes are appearing in the Arctic because permafrost is melting, trees are tilting, ice cellars are dripping, methane gas are escaping through the holes in the frozen surfaces of some lake, it can be lit on fire.
In The Martian, Matt Damon's problem with farming is that Mars is cold, and he has to make his own water. So instead of terraforming Mars, why not first make an ocean by making a lot of water? Once there is a sizable ocean or lakes, export some rotting biomass from Arctic, figure out a way to launch it like an astreoid that can be steered towards Mar, Arctic biomass probably got some Ice Age bacteria that can better survive on Mars. If our planet is warming because of Methane gas, wouldn't the same goes for Mars we make an ocean, add a lot of rotting biomass, and bacteria?
After Mars warm up we can add Mangroves, as Mars is very salty. Life in the ocean is older, could be simpler -- I think starting an ocean insead of jumping to terraforming and making Mars habitable for land animals instead of ocean stuff first is the way to go. I've heard of barley as a crop for Mars because of the salty soil problem, but um, the ocean is full of plant life that is cool with salt! So many seaweeds that are edible and cold tolerant.

DO NOT REDEEM!!!
If we don't do it, somebody else would, private corporations, and we end up with a dystopian future out of Aliens. There's probably precious minerals out there, and it's good to have a backup planet...and we probably blow money on stupid crap we shouldn't have spent on all the time. ...mostly, I envision something like, 'let's make an ocean first' as taking place over a hundred years... Instead of setting up tents and domes on Mars to grow potatoes, we do it the Walstad Method for Natural Aquarium way. we launch the ingredients for life at Mars and let the soup sort itself out.
you watch too many sci fi films, Elon
The martians will pay for it.
Elon got this
Let's cancel all the stupid Olympics and have a space program instead.
>instead of terraforming mars, why not terraform it ?
Most terraforming plans eventually involve trying to melt the poles/crashing ice asteroids into the planet
Neither of will work, as the planet does not have the gravity to hold an atmosphere dense enough to allow liquid surface water.
You would need to crash every single asteroid in the belt then every comet in the Oort cloud onto the surface for a chance of liquid surface water on Mars.
Fricking primitive Black folk.
Put one stargate on Mars and link to another in Europa's ocean and flood the planet
If we had the technology to make Mars into Earth then we would also have the technology to make Earth into Earth again.
Colonizing the moon or Mars adds the benefit of humanity surviving if Earth is hit by a giant asteroid or a Black Death-tier plague or some other extinction level event. Due to low gravity the moon can be used as a base to build and launch more ships while Mars could be a waypoint for deeper exploration of the solar system.
To what end?
You sound like a black.
In an event like that the Mars colony is fricked too because it wouldn't be 100% self-sustaining for a long long time, if ever. Even in the still completely science fiction scenario where a colony could achieve self-sustaining capability in material resources and solved the solar radiation issue, having kids might always be impossible due to the low gravity.
If you want a contingency for an extinction event, deep underground bunkers on earth would be 1000x easier to sustain than a Mars colony. If you want a launchpad for deeper solar system exploration, the moon does that job just fine as it eliminates the requirement to escape Earth's gravity well and atmosphere. There's just no reason for us to frick around on Mars any time soon
I think we should actually make Mars habitable for humans with robots LONG before we put humans there. There is just way too much problem relying on stored food -- see The Terror, two ships sent on an expedition expected to rely on canned food for 2 years, they gave the bid to the cheapest company, but even if it didn't, did they even experiment with seeing how people did only eating can food for 2 years before sending them up to the Arctic? They just didn't care, because by the time of Franklin's Expedition, the officers have guns so they don't have to worry about mutiny anymore.
Youtubber Canadian Prepper tried 2 weeks living off nothing but his preps, eg freeze dried food, which is higher grade than canned food, but he still note that he felt hungrier than usual. I think inspite of labels, food does lose nutrition when preserved. Malnutrition takes time to show up, so even though bread and rice are empty calories, I can live off nothing but bread or rice with water for weeks or even months and not die, but I will start to get sick. Before we send humans to Mars for anything more than a brief visit, we should really make an ocean first -- bacteria, methane, seaweeds -- then we can add shrimp, then fish! Cause I think in the long term we do need fresh meat.
Ok I don't know why you're so fixated on the food issue, there's way bigger problems
>the constant bombardment of solar radiation even if you're living underground
>the extremely fine electrostatic martian dust that will get in everything
>the physiological effects of long term low gravity
>the toxicity of the soil
>the psychological toll of living in a fricking box on a hellish alien planet
>the requirement to procure the raw materials for, and manufacture, every spare part you could ever need
>rescue missions taking 1-3 years if something goes wrong
>just the voyage there, the zero-g fricking with your bone density and cardiovascular system
>probably more stuff i'm forgetting

Sorry, we're too busy fighting wars for Israel and paying for 80 IQ third world immigrants to breed like rabbits to undertake any grand projects.
What have you contributed to the world?
what have you?
I'm not the one who made the argument that worthless people were holding down the human race. You are a worthless person.
Yep, brown.
>noooooo you're not allowed to point obvious things out unless you're Einstein!!!
You might have a point if the Nobel Prize winner scientist who discovered the double helix shape of DNA wasn't canceled for suggesting evolution didn't stop at the neck and different races have different cognitive abilities. homosexuals like (You) still don't want to hear attacks on your sacred cows from people who contributed to the world.
have you accomplished anything in your life? Anything at all?
I have a useful degree, a well-paying job, I pay all my own bills and I've never been on gibs so yeah I've contributed more than 99% of third worlders and third world immigrants. Do you want to address the argument about the West's shitty, misguided priorities now or continue the character assassination and background checks that I'm sure will never be to your liking?
that's not accomplishment. it's just doing the absolute bare minimum that the government commands you to do.
>that's not accomplishment.
It is. The fact that you have to try to find an angle to shit on it shows that you're likely worthless yourself.
Congratulations! You are a working cog in the sistem.
But, only a tiny, replaceable, cog.
You are a racist.

So the past 3 to 4 hours, I actually learned that Mars has no atmosphere because it has no magnetic field, while you two are just in some endless /misc/ circle jerk.
Oh frick off, he's right.
What is this ad hominem bullshit? Yeah yeah, attack the messenger, not the message. Well done!
Nobody said that. Well, granted, perhaps it was implied, but still, not good form.
He posted a funny meme image to an imageboard thread. What have you done?
Middle Easterners build civilizations while europeans lived in muddhutts for another 2000 years. Just saying.
US aid to Israel is 0.01% of US GDP
As I understand it Mars has basically no atmosphere, and it has a weaker magnetosphere than Earth so any attempts to create an atmosphere would be stripped away by solar wind. So any colonization of Mars would have to be entirely indoors and underground to create a breathable environment that's shielded from the sun.
In the Martian, Matt Damon was growing potatoes 'indoors', but then then when the tent ripped he lost his crops and the bacteria...now with an ocean, plants can grow in it without worrying about the atomosphere -- is the solar wind enough to whip up the ocean?
Yes? You know how it feels really humid on land around the ocean? And there's more rain storms? Cause the water doesn't just sit there as liquid always, it will diffuse up into the sky based on pressure. You can make water boil into vapor just by lowering the pressure. That ocean would not stay there indefinitely.
mars will never be terraformed because its a pointless exercise
humans build their own living space, we'll have space stations hundreds of miles wide with a living biosphere for a fraction of the time/cost
Because no atmosphere means no heat sink. You could flood mars with water, it'd just all freeze.
Okay, first we get water there, by crashing ice astreoids there somehow, then we firebomb the planet to melt the ice -- maybe we actually launch our frozen methane filled biomass there first, then burning it sends it up to make the atmosphere? How did earth get our atmosphere anyways?
Atmospheres naturally form when you don't have solar winds stripping all the gas off your planet due to an active magnetosphere. Mars doesn't have a magnetosphere anymore.
You'd essentially have to work out a way to get the magnetic field running again before you'd want to waste any time sending water to mars.
Interesting, I'm reading my way through this now...and trying to understand it...

// One major requirement for such terraforming is having the protection of a planetary magnetic field which Mars currently does not have. In this article we explore comprehensively for the first time, the practical and engineering challenges that affect the feasibility of creating an artificial magnetic field capable of encompassing Mars. This includes the concerns that define the design, where to locate the magnetic field generator and possible construction strategies. The rationale here is not to justify the need for a planetary magnetosphere but to put figures on the practicalities so as to be able to weigh the pros and cons of the different engineering approaches.
The optimum solution proposed is completely novel, although inspired by natural situations and fusion plasma techniques. The solution with the lowest power, assembly and mass is to create an artificial charged particle ring (similar in form to a “radiation belt”), around the planet possibly formed by ejecting matter from one of the moons of Mars (in fashion similar to that that forms the Io-Jupiter plasma torus), but using electromagnetic and plasma waves to drive a net current in the ring(s) that results in an overall magnetic field.//
Our atmosphere was formed by global volcanic eruptions while Earth was forming, the water cycle, single cell life and plant life. Gravity and the magnetosphere is what keeps Earth's atmosphere from drifting away. Mars doesn't have enough of either which is why most of their atmosphere drifted off to space. It's unfortunate Venus developed so close to the Sun. If Venus and Mars traded orbits when they were formed Venus would be a second Earth. It's very similar to Earth in most meaningful ways except for distance from the Sun.
Dude, algae and nematodes.
I've seen plans calling for bombarding it with comets before. The impact energy would generate enough heat to melt them.
The other Cinemaphile I watched a long time ago, was the Futurama episode where humans of the 21st century dealt with their garbage problem by making a giant garbage ball and launching it into space. When I was watching "Arctic Sinkholes", I was thinking, why can't we deal with our methane problem by launching it into space? Well if we could somehow get it onto the moon, we can later get it to Mars.
Better yet, why not turn methan into an energy source?
The problem is the pressure on the surface of Mars is only about 0.6% that of Earth, low enough for water and blood to boil which is why you need a pressure suit on Mars. Any water exposed to the surface of Mars would just turn into very cold water vapor
we need to bombard mars with asteroids and icy comments
I feel like The Martian (2015) is a funhouse version of Interstellar (2014)...not a single character in The Martian actually died in spite of the super outrageously risky things they did, whereas Interstellar had the constantly Dwindling Party, in space and on earth. Interstellar is about escaping Earth ("Mankind was born on earth, it was never meant to die here"), The Martian is about coming home ("that's enough space for a lifetime"), Matt Damon gets marooned on a cold planet again, but Jessica Chastain gets him out this time. China is supposed to be a villain in Interstellar but that got left out...in The Martian they were crucial in saving the American astronaut. Interstellar is a very manly movie with manly characters and manly virtues and sins -- Damon's character Dr.Mann is the villain because he's a coward. Matthew McConaughey's Joseph Cooper is the hero because he's brave, he's an explorer not a caretaker, the movie starts and end with Cooper leaving his daughter behind because he was needed elsewhere. The Martian is definitely a woman's movie with a woman's music and woman's heartthrob from her highschool years: Matt Damon.
In Interstellar (2014), farmer Joseph Cooper was a pilot who wants to get back into the sky, to outerspace, and he hates farming. In The Martian (2015), astronaut Mark Watney is a botanist. Cooper is an individualist, even the higher power turns out to be his future self in the end, and his happy ending was stealing a ship and going back to join a fellow widow in the frontier...and Cooper's closest friend is the robot, which is kinda like his dog, he's not a teamplayer. Mark Watney is extremely social, his crewmates are also his friends, he stayed alive because he's smart and hardy, but his crops fail and in the end it was a group effort that saved his life and brought him home.
the Martian was I fricking love science the movie.
It's kinda weird how Interstellar is the stark manly movie but the ending leaned more towards Fantasy than Science, while I Fricking Love Science is unrealistic when it comes to the odds, but there wasn't anything fantastical in it like all those point in time connected to a little girl's room. Interstellar felt kinda like Ray Bradbury's speculative fiction, especially Martian Chronicles, and The Martian was like Disney In Space -- back when Disney was good at crowd-pleasing.
As soon as Sean Bean showed up, I wondered how he was going to die in this movie, but he didn't, because NOBODY died.

Mars can’t be terraformed without a magnetosphere or something to simulate a magnetosphere. The core of the planet is dead. The core of our planet is maintained by the tidal forces of the moon and sun.
What about something like a bio dome then, with multiple layers of aquarium grade acrylic in place of an atmosphere?
Why bother with an atmosphere on Mars if its gravity is too weak and the inactive magnetic field means that all the gas will escape?
Hey
We won't do anything good with Mars until we have anti-gravity*
Once we have anti-gravity we won't need Mars
*any form of reactionless propulsion
Nobody is ever going to go to another planet and there definitely will be no terraforming or space mining. Its expensive and pointless.
We will live in the asteroid belt
What do they eat?
They have things like the protein farms from bladerunner. And then try to form it into imitations of normal food to be palatable, but it has a different taste and texture. Some of the outer moons can grow more real stuff like modified plants and they ship to each other. They have some other plants on the rocks and there's scene where people are hungry and start eating those plants. A scientist remarks that those plants are not nutritious at all and only there to help with the air, so it's just a harmful waste.
Mars isn't going to be viable until it has a magnetic field.
Total Recall?
yes
Terraforming takes million years so no one cares about that. The best we can do about Mars is to suck it dry from all resources.
