Bump

lmao its this autist again
based

>>12053628
by autist i think you mean genius, welcom fren

>>12053611
It takes a shitload of delta-v to get to Mercury, and there's no atmosphere to aerobrake when you get there.

>>12053639
not much more than required to get to any of the Galilean moons.

>>12053642
okay but we aren't talking about colonizing mercury vs colonizing the galilean moons retard
it's a FUCKTON easier to get to mars than mercury

>>12053644
mercury has more resources and energy on it, so its worth the initial launch difficulties

>>12053656
okay why dont you go build some rockets and get at it champ

>>12053657
i dont have billions :'(

we shall call it...
earthcury

>>12053660
in fact ive been jobless for decades

>>12053677
why u gotta do me like that man...

>>12053611
far too close to the sun

>>12053684
not really, it being close to the sun is a great thing for solar power

>>12053611
>>plenty of energy
Maybe a little too plentiful I'm afraid.
The article is very interesting but I wonder if those conditions are compatible with mercury's low rotation.

>>12053691
Dumbass.
Solarpanels lose efficiency past 25C

>>12053705
imagine being such a brainlet that you think well use solar panels holy fuck lmao, obviously we'll use solar stirling engines

>>12053704
its rotation isnt even that slow

>>12053611
Broke: terraforming Mercury.
Woke: disassembling Mercury and constructing a swarm of solar powered habitats.

>>12053711
*sigh*
It's 450C in Mercury.
It doesn't matter what energy source you want. The infrastructure needed to build it would just be destroyed within a matter of days.

>>12053721
lmao no, its not 450 Celsius, 6 feet under the ground it never gets hotter than 160 Celsius at the equator and at higher longitudes its 20-50 Celsius year round, literally all you need to do for heat management on mercury is reflect the light away

>>12053721

>>12053721
literally all you need to do is sprinkle a section of dirt with white paint to raise the albedo above 0.8 and then the temperature under the first few feet or so is 25 celcius year round

>>12053751
Yes , just camp at the comfy cool craters at the poles

>>12053751
You know-it alls always come here acting like you know more than the experts and think that your idea was never thought out

>ultraviolet rays
>solar rays
>dust storms
>solar flares
>magnetic storms
>alpha and beta particles
>coronal mass ejections
Whatever solution you think off would take far more effort than simply focusing the resources on Mars, Moon, and asteroid minning

>>12053772
1. uv rays are easily blocked
2. not much particle radiation reaches the surface, mercury has a magnetic field ,and although 100 times less than earths this is time thousands of times more than mars. and enough to nearly totally stop radiation from reaching the surface except in some parts of the poles.
none of this is a difficult problem

>>12053787
Shut the fuck you know absolutely nothing over the sun's magnetic storms that would destroy any and all electrical circuitries that was not protected by a powerful enough magnetic force. Which neither Mercury nor Venus have

>>12053772
radiation doesnt scale linearly with field strength, a magnetic field 100 times weaker doesn't mean 100 times more radiation at the surface, Mercuries surface radiation is much less than mars despite the radiation flux being 14 times higher at that orbit

>>12053796
Conveniently ignoring the fact that Mercury is nearer to the sun, I see

>>12053793
lmao you're retarded, mercury DOES have a magnetic field powerful enough to block flares and storms. its the only other terrestrial planet in the solar system other than earth which DOES have a powerful magnetic field retard, during flares active magnetic shielding and a Faraday cage over the base would be ample to stop any electrical dmg

>>12053799
nope, i didn't i just stated that the flux was 14 times higher this close to the sun, but its magnetic field is enough to block more radiation than mars

>>12053802
the solar wind doesnt reach Mercuries surface

>>12053802
>>12053804
Mercury's magnetic field is 1.1% the power of the Earth.
And the Earth has suffered a major solar ejection that destroyed all telegram communications back in the 80's

You build your Mercury colony and all circuitries shall be destroyed overnight and the sheer amount of electromagnetic forces from the sun would prevent any form of communication

>>12053611

>>12053807
1.1% field strength doesnt mean 100 times stronger surface level particle radiation you fucking retard. Also even during the worst flares literally all you need to do is turn off the electrical appliances ect during the few hours for the storm, and just cover important electronics with faraday cages, flares are only disastrous on earth because we built our infrastructure without protections in place and now were fucked, but on mercury everything would be protected from the get go https://www.nbcnews.com/mach/space/how-we-ll-safeguard-earth-solar-storm-catastrophe-n760021

>>12053824
Ah, yes, turn off electricity of a colony in an inhospitable planet.
What could possibly go wrong.

>>12053831
Yes because on mercury unlike anywhere else in the solar system you won’t freeze to death if electricity is out for a hour or two, as long as everything is airtight, you could go days without electricity

>>12053863
>no life support systems like oxygenator (gold box), air circulator, carbon dioxide removal temperature regulator, contaminant and particulate control, water management, waste management, and so on

>everyone dies of suffocation.
What are you gonna do? Faraday cage the entire colony and prevent any form of communication?

Thanks for the laugh, retard

>>12053831
In fact, mercury is the only place in the solar system other than earth where temperature can be regulated passively at surface level just by having your colony 1-2 meters under the soil, it’s the only place you could just make a lava tube airtight and the temperature is 25 Celsius year round without needing todo any heating

>>12053870
You don’t need temperature management you fucking retard it’s done passively by conduction on mercury because subsurface temperatures are 26 Celsius year round for large parts of mercury. And you can go without all of that stuff for a hour your fucking imbecile, you won’t run out of oxygen in a decent sized colony in 1 hour holy fuck, and water and waste turning off for 1 hour every few months is a joke lmao this is not a difficult problem

>>12053877
We're talking about unearthing hundreds of square meters off the ground, building supports to prevent a cave in, destroy any harmful chemicals under the soil, and of course, make it completely liveable based off temperature, air control, and water management.

If we cannot dig an asteroid for minerals, we cannot dig Mercury. Period

>>12053884
Mercury has kilometre sized lava tubes you idiot already, just seal them and it’s done, again you don’t have to do anything at all to make it a liveable temp, just seal it and pump it with air and you’re good to go

>>12053882
Actually, no. It's not the lack of oxygen you should worry about
It's the circulation of air

>because the air is no longer circulating, the carbon dioxide you emit would stick right on your face instead of moving away leading to a suffocation.

>>12053890
Co2 doesn’t stick to your face you absolute retard, it immediately sinks to your feet, all you need to do is have some plants and some sky lights that are tinted and Uv reflective (literally a car window) and it takes care of itself

>>12053888
It's always the retards who speak like it's a feat so easy it sounds like a scam

Got a geographic map of Mercury's lava tubes?
Are they in temperatures that are liveable?
Can robots traverse the terrain?
How do you intend to "seal" them?

Always acting like some hot shit.

>>12053896
Ah yes,
"all you need"
"simple"
"you just have to"
Words straight from someone who knows nothing.

Do you know how much plants you need to get rid of that much Co2?
Do you even have a plan over how the place would look like and be acomodating both for living and research purpose?

No you don't. You're just completely deluded by popsci

Enjoy the constant solar flares and scorching temperatures.

>>12053904
3/5

>>12053910
Don't give me that, bro.
It is not impossible
But as far as research goes, Mars, Moon, and asteroids are much better and easier targets

That's just how it goes

>>12053918
A small paper I wrote on the topic I’m not pop sci retard

>>12053932
I'm reading it right now
You speak of living inside lavatubes but have no idea of where to find one and where to find one that is big enough
You graze upon the topic of radiation shielding but made no mention of communication
You speak of light sails but have no idea that they are a meme because in order to build one, it needs a room temperature super conductor with as much as 3cm diameter
I cannot even find any mention of how you plan to power the base and keep it protected from solar rays.
And worst of all, who the hell uses ALL CAPS on their paper?

Move along.

>>12053945
We’ll send probes first to locate the tubes, solar sails don’t need room temperature super conductors lmao you’re thinking of magnetic sails,
You can power the base with solar Stirling engines, and I did mention protection? Active magnetic shielding and passive shielding from the Minimum 2 meter thick layer of dirt on top of the colony

>>12053964
Only 6% of mercury has lava tubes. We don't know how much of that is liveable. Just wait for a technology that can mine asteroids so you can also dig in mercury
Any form of energy source that is dependent on weather is bad and dangerous for colonies. Just go nuclear. You can place that inside the underground base with proper radiation shielding
I still hear nothing over how you intend to keep a communication line going in a planet that is heavily bombarded with the Sun's magnetic force.

There are ways to colonize Mercury but it is bound to be much more difficult than what we have now.

Not to mention the cost-effectiveness. A single 1-km M-type asteroid contains more gold and platinum than what our biggest mines could harvest in a year. 1 single asteroid is enough to crash the market and make super computers cheaper

>>12053973
Fibre optic?

>>12053973
There is no bad weather on mercury, there is no such thing as a cloudy day. No dust storms either

>>12053980
If you have to build it outside, itls bad because people have to leave to maintain it

>>12053988
Why is that an issue? If your suit is reflective and the soil is painted white there will be no issue with temps, radiation isn’t a big issue if you only need to repair every now and then and active magnetic shielding of the area during repair and maintenance is simple

>>12054002
Morale and time.
It takes 45mins to wear a space suit and we don't want anything exposed to uv rsays and chances of meteor shower

bye

>>12054010
The orbit near mercury is clear, all small asteroids have been cleared out long long ago. And if rays are blocked by paper lmao . Uv rays don’t penetrate clothes let alone a airtight space suit

bump

On Mercury you can just block UV using sunscreen lotion, like WTF that's not even a problem...

>>12057430
This, I mean you won’t be exposed to uv very often, at all times you’ll be wearing a space suit outside and uv can be filtered quite easily With films over windows ect

All this talk of terraforming other planets, why don't slow down and start with a test run, say Australia. Why not terra form that first and see if all the other shit can come next
