Yeah, but what does "massive" mean in this case? Venus is mostly covered in shield volcanoes. You could get some pretty serious flows but if we're to the point of unironically terraforming Venus into a human-habitable state I think we could deal with that kind of slow activity.

>>10960887
the most common idea is cloud cities, this could be done fast and needs no terraforming
another approach is to shield Venus from sunlight with some giganormous umbrella and freeze out carbon dioxide from the atmosphere, this would take at least 300 years and and you only get a deep frozen planet with dry ice
to turn Venus in a second Earth you need plate tectonic, there is some volcanism so it's possible, but naturally it would take more then a million years, maybe we can speed it up by crashing asteroids into Venus but how would we do that?

No. The timescales are immense. Venus has two problems from a plate tectonics standpoint. There is too much sulphur making the rocks soft, and there is too much superheated co2 which prevents lava from cooling. Big, big problems but not insurmountable.

>> No.10962620

>>10962617
We could mine all the sulphur (it's useful as a construction material) and send it to space. Then we bottle all of the CO2 in giant pressurized containers and send it to Mars so we can build the atmosphere there.

Venus colonization might be practically impossible. Venus might have turbulence that is too strong to build practical Venusian colonies. We have observed clouds on Venus that appear similar to cumulus cloud columns on Earth.
https://mipt.ru/za-nauku/upload/medialibrary/462/Titov_2011_Morph_cloud_top_VEX_monitoring.pdf
This might indicate the existence of thunder storm level turbulence on venus. The real fuck you might come from a recently observed atmospheric wave on Venus. On Earth, atmospheric waves have been known to tear airplanes apart. This may not be the case on Venus as said colonies are much much higher than than the ground, but the fact that we can image the wave means that the ground is interacting with the cloud layer at which our colonies would be. If this wave does produce strong turbulence, there is no way for our colony to avoid it.

>>10964306
The Soviets sent two French weather balloons to Venus as part of the Vega program. Peak wind gusts were measured to be 3.5 m/s and there are indications of convection cells of about km in diameter which may be comparable to the size of a well developed colony. That might be worrisome. Akatsuki has also found that winds on the nightside can go as low as 70 km/h in some places which is interesting because Venus atmosphere is supposed to be spinning faster than the planet. This might indicate that the nightside is weirder than we thought:

>>we don't know for sure
we don't know for sure that we can build practical colonies there either. For venus colonies to be practical they need to carry as much payload as possible and last a long time. While extreme turbulence might be rare on venus it might be something our colony has to contend with over its lifetime. Which ideally should be more than 20 years. Low colony lifetimes also mean you can't really colonize venus because you can't build colonies faster than you can replace them. If we have to build an armored colony or a colony that can move we decrease the amount of payload our colony can carry while increasing the cost of building said colony. Increased cost also makes it more difficult to build new colonies faster than they can be replaced. Finding that these once in 20 year events exist by a weather balloon probe might be difficult. But if we observe any at all, then venus colonies are pretty much screwed. Honestly, Akatsuki might be able to give us a pretty good idea if colonies aren't possible.

I bet so, kinda sad and disappointed that there isn't good news about it but still I would love to sent a teflon coated zeppelin to the planet and properly investigate the planet surface and habitable side of the atmosphere.
maybe even discover the impossible and find photosynthetic black bacteria.
I would love to visit that planet since its the only planet that is earth-like enough.

bullshit. The only thing we know capable of behaving as a superfluid is helium-3 at cryogenic temperatures. It's a supercritical fluid though. There's a huge difference between superfluid and supercritical fluid. Density at the surface is about 64 kg/m^3 which is still way less than the least dense liquid.

it's still going to be closer to a zeppelin than a submarine. The atmosphere is way less dense than water. However if you have people inside, then it will resemble a submarine in some ways. We will need to have a cramped pressure hull like a sub. It will be some what cramped because to minimize the volume we have to keep cool. And if we ever want to return from the surface, we need to be able to float much higher up in the atmosphere.

You are right about the heat. It is the biggest engineering challenge to manned exploration of venus. I suspect that dives to the surface would be time limited. The vessel would need to rise to much cooler altitudes to dump heat. When whatever substance we will use as a temperature modulator cools it would condense. During the dive this heatsink substance would gradually heat up and expand into a gas.

Up and down. Rising high enough and trying to maintain your position on the nightside would be key goals. The pressures are negligible. We can already craft pressure vessels capable of withstanding surface pressure on venus. The heat though... You need insulation and some kind of crazy heatsink substance. It's just so possible.
