Can you really grow potatoes with martian soil?

Space is fake, newfag. Seriously. Those mars rovers are the most obvious hoaxes in the world.

>racist
didn't he literally have china give vital tech for the rescue mission out of the goodness of their hearts

>I GOTTA SCIENCE THE SHIT OUT OF THIS

40% of interactions online are with bots, it was less than 10% a few years ago. Ai is getting crazy

why would I take a brown persons opinion on scientific matters?

True. Science fags explained pic related as wind erosion lmao

The book is hard sci-fi, basically everything except the inciting storm works out. The book does not end on the bullshit Iron Man ending.

You have to have microbes in the soil to break down the nutrients and make them plant available.

To add to this, there is wind on Mars with storms iirc, but the actual atmospheric pressure is so low it doesn't matter.

he mixed his shit with the soil in the books for nutrients and bacteria. don't know if they did that in the movie.

He used shit

Have a (you)

The author was actually mad because with a little more research he learned...no it wouldn't work. The soil is slightly too irradiated for potatoes to grow and doesn't have enough nitrogen and even in optimal situations he'd only get about a quarter of a crop or less than 6000 calories to keep him alive. The astronaut would have a better chance being overweight.

Anybody else feel like we should send drones with earth life to mars and just see what happens? The planet is dead as fuck like I don’t think we can make it work. Some really tough bacterias and shit can probably live there, and given enough time life will diversify.

Not directly no, the soil is poisoned with perchlorate compounds which means you have to run the soil through water a shit ton before it becomes even plausible.

Worse*

Your brain is a pattern recognition machine. That is a rock

>Using germ warfare on the Martians
You're just asking for an invasion.

Yes, of course. A rodent exist on Mars!

I think a rough idea was to get liquid water out (Elon said nuke the poles but wtf does he know) and then get some algae going to produce a breathable atmosphere to start up terraforming.

Book called Seveneves they drop ice on a dead world to add water. Terraforming is basically Cup a soup I guess.

>The planet is dead as fuck like I don’t think we can make it work.
But they always claim that water, ice and maybe even (live) bacteria exists there already.

think of the myriad of things humans have done with good intentions only for them to have horrific consequences. how in the world could you possibly think this is a good idea?

I don't see why not. As long as the PH isn't crazy it should be no worse than growing in sand.

The real redpill of mars colonization is that nothing mentioned in this thread matters at all when it comes to long-term stability of a terraformed environment, without first putting a huge dynamo at Mar’s L1 lagrange point to act as a magnetic shield

Mars doesn't have a stable magnetic field so it will never hold atmosphere.

The Ph isn’t ‘crazy’ but it is noticeably alkaline because of perchlorates

I’ve looked into it pretty far. The planet doesn’t have enough gravity or magnetic field for a proper atmosphere. It’s pretty much fucked so we could never leave pods. Then you start to realize it’s not even better than a fully man made space station.

We can’t do shit unless new physics or hueg engineering allow us to create a massive field that keeps an atmosphere in place

I'm all for bombarding Mars with Earth life and seeing if anything sticks.

Probably something like Everest lichen or Antarctican algae would do the best.

just blow up the sun instead. no more pesky solar winds.

Moon base or asteroid base are better choices than a free-floating station. Better to move to where materials are.

I always thought that xbox-hueg engineering projects were the most kino of ways to get around problems in sci fi, because it shifts the fiction away from the science and towards people actually working together

No, the real redpill is that if you give a Mars an atmosphere it will take many millions of years before any considerable amount of it gets blown away by solar wind. Magnetic fields aren't necessary unless you think in time scales of the millions. It's easier to just resupply the atmosphere at that point.

>Moon base
aeiou

It is pretty cool and I agree sci-fi shit where “we found the new property of physics” is too easy. The process for making bigger and bigger shit is interesting. You have to make thing to make the tools to make the bigger thing to make the tools to make the bigger thing etc etc. it’s probably more realistically possible than people think for us to make huge shit

Technically, if we did something like we could get mars to have a ‘breathable’ atmosphere, but it would be extremely arid because Mar’s gravity is too weak to hold onto water vapor at human-livable temperatures. You could always periodically crash comets into the atmosphere to replenish it, but it would never be stable and would take constant work. So at that point just build Babylon 5 until your solar shade in front of Venus starts paying off thousands of years from now

No it’s implied that NASA had to pull a shitload of strings iirc, basically promising them like half the next mission will be chinks in space. They then market it as a multinational charity mission because they’re constantly running to fix their fuck up.

let's teraform mars! NOW!

Planetary bodies with low gravity and no magnetic field lose would lose their atmosphere, but it takes a shit load of time for that to happen. If you're able to give them an substantial atmosphere you won't need to think about that problem for literally tens of millions of years.

IS THAT A TINY LITTLE CROCODILE MOUSEY?? ON MARS??? MY EYES SEE IT MY BRAIN SEES IT, HOW COULD ONIONS-ENCE LIE TO US????

that is less convincing than this. check out the big rock on the left middle.

It's got what plants crave.

So Elon is right. Just nuke the poles. In a million years we will probably be either extinct or have god tier technology

post the original photo with onought resolution to check myself or suck my dick

mars is too small, i prefer terraforming Venus

you only want to do that because venus rhymes with penis and you are gay

what am i supposed to be seeing here?

you guys are funny, like you're here to amuse me, like you're clowns haha funny guys

immense milestone day

yeah so we're pretty much doomed. i think there's a good chance humanity doesn't get its shit together and most of the world just dies. if some humans keep going, then cool i guess, if not then life will still exist on earth and within a timescale beyond our comprehension it'll recover. like how a ton of shit was wiped out with the dinosaurs but life kept going anyway

I couldn't finish this movie. I was 2/3rds done and quit it out of how gay it was. EVERYTHING goes right for this mcguyver nigga. Typical feel good movie yawn inducing movie for normies.

The poles doesn't have nearly enough frozen CO2 and water to create a dense enough atmosphere to make any real difference even if you vaporized all of it. Only realistic way is to direct comets and asteroids with high water contents towards Mars and have their vaporization create an atmosphere. The surface pressure on Mars is 0.6% of that of Earth. You need to get that to 20% for humans to be able to walk on Mars with just an oxygen mask (considering it's a very warm Martian day and you're protected from the radiation).
