Yano how the sun pulls things towards it with gravity? In the future, when Mars is pulled closer to the sun and in the ‘habitable zone’ that earth is in now… could humans live there and engineer it to be like an Earth 2.0?
Anyone know how long it would take Mars to travel said distance to the habitable zone?
Would it take so long that the sun would be dead before it happened?

Mars has a shit magnetosphere. Even if it were in tbe same orbit as Earth it would not be habitable by humans in the same way Earth is.
magnetosphere won't be too big of problem if mars has thick atmosphere bcuz UV rays will simply be abosrbed in atmosphere and not redirected to poles
ASsuming Mars is in new habitual zone, CO2 might melt from the dry ice poles creating slightly thicker atmosphere (shooting nukes at poles now to release CO2 would have barely any influence at atmosphere dispite what Elon M is says. Nukes are tiny compared to a planet)
new O2 so get some plants
might work
not a scientist
>when Mars is pulled closer to the sun
not gonna happen
red giant phase
stll not pulled anywhere
That's in like 2 billion years.
stop bullying
It used to be a habitable planet, you ass.
humanity will be loooooong gone.
People say we're like cancer for the earth, no we're not, we're more like a weekend flu, we'll be all gone and earth will be alright.
>not a scientist
We can tell..
BTW anyone who is still thinking of Europa needs to get with the program and start thinking about Enceladus.
It's shooting water right out now. Prime visitation material. Stop thinking about Europa (and to anyone else: stop hoping that Mars is our lifeboat)
impossible. earth is flat
can someone explain this pic to me. (I'm aware the reason continents change in size between different Earth photos is due to how close the camera is to Earth (closer = conts look bigger)).
Yeah
Good thinking' newfag.
That's why the terraforming needs to start now.
Mars is already in the habitable zone ya dingus.
The sun is heating up because of Hydrogen being burned and turning into Helium, the goldilocks zone is moving out toward Mars and when it reaches we probably won't be in it any more.
Mars has lost all of the things that could possibly make it habitable a very long time ago, around three billion years or so.
The molten metal core has cooled and so there is only a miniscule magnetic field, certainly not enough to protect people from the solar wind or cosmic rays.
The water is 70-80% evaporated along with Mars' atmosphere, it's around -30 degrees Celcius on the surface on a warm day it can reach minus 10.
Mars is significantly smaller than Earth and has a much lower gravity, this would cause a multitude of physiological ailments that we don't know enough about yet, it in all probability will be very bad.
so what exactly bothers you about these pictures?
moon got big
It’s because the earth is flat.
who are you trying to confuse with this bullshit?
i'm sure the stupidest user here has heard of cropping
>the moon...got...big
Congratulations, your brain is officially less useful than a dried out dog turd.
are you saying the picture is fake or what are you saying. explain
Mars is already in the "habitable zone" you fucking retarded brainlet, the causes why is a fucking dead rock are others
This stuff fascinates me. How realistic is terraforming a planet like Mars? Is it the best prospect in the solar system to be terraformed? I remember reading the Red Mars trilogy and didn't they bombard the surface with icy comets? Seems like such a massive project. Is terraforming a pipe dream economically speaking compared to giant O'Neill colonies with perfect climate and rotation to provide gravity?
He's not bullying, the sun will expand but won't pull anything towards it.
That's not really how orbits work op. We aren't going to fall into the sun or get (much) closer at any point in the sun's lifetime without some outside influence. We'd burn up from the suns inevitable expansion first. For a brief period then Mars will be in the goldilocks zone. But as another user pointed out, very little as far as magnetosphere. We'd be better off colonizing one of the many moons on Saturn or Jupiter.
people like you make me sick!
Using energy equivalent to the amount of sunlight that hits the Martian surface, we could introduce a greenhouse in about 10 yrs. Oxygen would take about 100. We cannot een fathom coming close to this amount of enrgy though. also i may be wrong
Well we sure need to understand and learn to take care of out own planet before pretending to terraform anything.
That being said, the main problem is the time to do it, as we'll need to produce more usable material (oxygen and food mainly) than we use, so the place won't be suitable for human life before a sustainable balance has been reached.
IMO terraforming will have to be performed automatically by robots and guided from earth, that's the best/safest way.
>a pipe dream economically speaking
I wonder at what degree of deterioration of our own planet and/or society the economics is no longer a determining factor. Let's face it, our planet is going to need to be on the very brink of annihilation before anyone dreams of lifting a finger without concern for personal profit, and even then I'm not sure it could happen. Planet about to be destroyed and I can't get on the spaceship to escape? Fuck you buddy. No, our own greed will keep us from ever expanding out into the universe in any meaningful way. Our species will die out here and the rest of the universe will be all the better off because of it.
"people like you make me sick!"
Glad to hear it.
And I'm your real dad,too.
should we fix Mars or fix Earth
lol, do you honestly think anything close to resembling humans will be around in 2 billion years? also the earth itself wont be inhabitable for life at all in 1-1.5 billion years.
i said STOP BULLYING
not bullying, asking a legit question
think, dont emote, or assume, im not being hostile.
For about 1% of the history of the solar system it had atmosphere and some water. That atmosphere was as likely to be horrid methanes and volitiles than the nice lush oxygen hydrigen nitrogen mix we have on earth.
the issue is it has no electro magnetic sphere to fight off solar winds so it can't keep its atmosphere
therefore this planet is no longer habitable but it has been in the past
lucky I can't ban you for making threats
threats? me? what threats? i dont think i am the person you think you are talking to.
We should make giant rockets strapped to Earth and ram into the bastard, for the lulz.
Agreed.
Personally I wonder if the sun's expansion will make other planets habitable. For instance, if the expansion happens fast (kind of like and explosion) it may push away some planets that are too close to be inhabitable now, and if that happens Venus would be the perfect candidate...
op are you fucking rarted
don't you dare tell me what I think and don't think. typical /b incel wants everyone to conform to their worldview
rofl, ok, im just going to leave this alone, you have the wrong person, theres no point in me continuing this.
Titan might become habitable short term while the sun is swole. In fact it may harbor methan life right now pretty cool
Yano how earth's centripital force from it's rotational velocity exactly offsetts the sun's gravitational pull?
many of the moons will be warm from tidal forces. would only need sun for growing food, and by then that may not be necessary.
Sounds like a conspiracy.
Mars is travelling at a velocity that keeps it at the same distance from the sun.
If Mars slowed down it would settle in an orbit closer to the sun and if it sped up it would be further out.
I'm majoring in Astronautic Engineering and this thread gave me cancer.
explain
>I read a some replies
>I contracted 6 different types of cancers
Only if the Hypotheticals put a spin membrane on us.
red giant doesn't have more mass. it's just more volume. if anything the sun's gravity will be slightly weaker due to the mass it will have ejected over the 2 billion years it will take to become a red giant
Mars will not get closer to the sun. Mars has been orbiting the sun for over 4 billion years, and will continue to orbit the sun at it's current distance for more than another 4 billion years
Quality book
it could be done now if we pollute the shit out if it.

what is your opinion on the James WEbb telescope
this is a very odd question
Wouldn't work. Solar winds would blow it away.
are you the same person who spends at least 10-60K a year on an astronautical engineering education
no, I'm the person that spent 70k a year on a physics/astronomy education.
Also, "Astronautical Engineering" sounds completely autistic as fuck and I don't know why you wouldn't just call it aerospace
How do we deal with these two problems with long term space travel/colonization? The medical effects of lower gravity on the human body and risks of prolonged exposure to radiation
what about nukes? like they said just before simply polluting it
aero:
air, atmosphere; aircraft; gasses
ultimately from Greek aēr air
No air is space brav
Rockets need to fly through air, because we launch them on Earth.
mars requires an iron core,earth acquired one around some time after it coalesced 4.2 bil years ago,a planet sized body clobbered us/it,a huge explosion that caused worldwide 2k degrees,and a buried small moon sized glob of iron/.nickel
that increased the gravitational field,added the magnetic field which protects b's from solar burps & corrosive radiation,
mars may have had a super civilization a billion years ago,and lost it because of no or low strength magnetic core,the atmosphere was burned off by solar storms.a massive bio/ geo engineering job is required to bring it up to habitable state
If I notice the other replies are more intelligent and discussive than mine does that make me the worthless shitposter
Fucking hell man, it could be that the martians terraformed earth because they had to move and the information got lost...
It doesn't have a magnetosphere to contain a suitable atmosphere. So no it couldn't really be Earth 2.0 it'll always be a highly artificial environment.
