Venus more like penus lol

How would you even begin constructing anything of that scale?

>>136112
It isn’t as hard as you think, it would probably be achievable in a century or so. How I think it would be done is you would make millimeter thick mirrors on the moon and launch them in bulk to Venus, either putting them together to make one big shade or using them as a swarm around the planet.

>>136114
I'll admit I don't really know much about space, but is the material necessary to produce these mirrors & rocket fuel present on the Moon? What material are you even thinking of for the mirrors? When I hear "millimeter thick mirrors" the first thing I imagine is them breaking in transit, though I suppose that's a very terrestrial concern applicable only where air resistance is substantially present. In a vacuum, I guess the biggest concern would be ensuring the impulse of propulsion is as evenly distributed as possible upon the mirrors' surfaces and/or that they're rigid enough to withstand said force. We're setting aside the practical concerns of money and not enough people really caring, I assume?

Ok what you accomplish is coalesce co2 into ice-age-tier dry ice glaciers. That leaves you with an atmosphere with zero oxygen and way too much nitrogen. So much nitrogen that the surface atmospheric pressure would be a few times higher than that on Earth. Which isn't the end of the world ig but less than ideal, especially when you consider the "no oxygen" part. That is a lot of oxygen missing and afaik you can't just extract it from dry ice directly unless you are some kind of special plant or bacteria that can survive in the environment described.

That puts you not exactly back on square one but in a spot where you have nothing else to do but slowly melt the co2 so that the space bacteria photosynthesizes you some o2 and space potato for Venus Vodka. Come to think of it, don't you need water for this process to work? There is none on Venus. Maybe you could capture and hurl asteroids with ice at it, or melt and neutralize the now-frozen sulfuric acid clouds?

Sounds like a lot of work. Doesn't help that if the orbital mirrors somehow fail everyone would get pressure cooker'ed.

Venus does have a few things going for it like gravity, but considering the amount of resources required for getting another Antarctica, flinging a generation ship towards Alpha Centauri doesn't sound like that bad of an idea.

Ah, reminds me of reading aerospace engineers' memoirs where back in the 60s they were fully expecting permanent Moon bases by 80s. Today, we have abandoned that dream for funny dancing cat tiktoks.

>>136116
The moon does have everything you’d need. Regolith can be made into mirrors and anywhere with water you can make rocket fuel.
>>136117
I feel the oxygen could be figured out but the nitrogen will be a problem. On Earth nitrogen makes about 70% of the atmosphere while on Venus it’s 6%. I suppose density might make up for it though as Venus has about 4 times the nitrogen earth does. Not great but certainly manageable to fix. I suppose you’d collect nitrogen gas and try make it react with something to create a solid like ammonia. Water is actually not that bad, you have readily available oxygen from the CO2 and sulfuric acid has hydrogen along with oxygen. You can extract these elements via Electrolysis. It would still suck mega dick but every terraforming project does, and out of every option it’s by far the most feasible.

>>136119
>on Venus it’s 6%.
If you remove CO2, it will be more or less the only gas left in the air (and yes there'll be a lot more of it hence the thicker atmosphere).
> you have readily available oxygen from the CO2
If you have near unlimited power and plenty of time then yes. The process is very energy-intensive and, ironically, requires heating the gasses (the plan was to cool the planet btw). At this rate one may as well settle under the icy crust of Titan or something. Just send Earth entire supply of uranium to power the terraforming stations for a while. Unfortunately however a child is starving in Botswana so we must bomb Tehran again. The most that can be allocated to NASA is .5% of the total budget.

>>136119
Is there enough lunar water for such an operation? I wasn't even aware the Moon had any until now. But it looks like only trace amounts have been discovered and it's an active question.

>>136126
You would just do this in select facilities instead of frying the entire planet. This is just me personally but I think near unlimited power can be found and it comes from manipulation of the atomic instead of like a Dyson Swarm or something. Ofc like you said the science budget would rather go to    learning how trans Hebrew dogs combat gender dysphoria instead of how to manipulate matter to our will.
>>136128
You don’t actually need that much. Just in general and also you don’t need that much fuel to even get off the moon to begin with.

I suppose another idea instead of full blown making the whole thing livable would be to treat it more like a mars that doesn’t suck dick because making those dome cities like Elon likes to hype up would actually be rather feasible in this environment. You would just need an oxygen mask and appropriate clothing to go outside instead of a full blow space suit.

>>136129
>You don’t actually need that much.
Maybe. But you're still relying on a hypothetical here. What has been found is trace, isn't it? And it may not be that expensive per se to get off the Moon, but now multiply that by the sheer number of launches and the quantity of material you'd be transporting therefrom to Venus. I have a feeling you'd have to confirm beyond doubt a more substantial presence of water on the Moon first.

>>136131
It’s about 20% the mass of some ice rich craters. Keep in mind however the timeline of a project of this scale also stretches a bit into the far future sci-fi so access to  further deposits of ice isn’t far fetched.

>>136129
> near unlimited power can be found and it comes from manipulation of the atomic
Well, controlled fusion is coming along...slowly.  Still seems like the most promising avenue for research. It still pales in comparison to the effort required to pull terraforming off, now that's an enormous multi-generation endeavor that requires vision and patience. Welp, won't be seeing that any time soon; would be nice to at least long enough to watch a permanent Moon base to finally spring up.

>>136136
I just like the idea. Turning Venus is to super hoth is such a cool contrast.

>>136132
Oh. Okay. So I guess the greatest problem to get over really is just getting everyone on board, especially if it's a multigenerational project and a good number of us have decided it'd be better to just pull the plug on everything anyways. lol.

>>136138
Exactly. We can get to becoming living gods after we can figure out how to care about something for longer than an election cycle.
