Get on the HAVOC train lads.

It's time to go take a look then.

>fucking BALL of PISS
at the surface, but not higher up in the atmosphere. The sky might look something like pic related. I was able to find some venusian spectral data with altitude and it doesn't seem to change much from orbit to 55km.
>> atmosphere is ridiculously dense
meaning we can potentially float big fucking colonies.
>>"Air" is carbon dioxide
Mars has an atmosphere of carbon dioxide that has a pressure of a couple of pascals, meaning any trees or diatoms you put there would become desiccated and freeze. On Venus you at least have the chance of keeping them alive at around 55 km. Just put em' in a plastic baggie that semipermeable so as to allow CO2 through, but not sulfuric acid.
>>REALLY FUCKING HOT
then don't colonize the surface. Colonize the area around 55 km where's only like 29 C and pressure's close to what you'd find on earth.

Venusian, not Venerian.
>>So, /sci/, why aren't we heading to venus?
well for one, we have yet to launch and deploy any large scale balloon probes. Second, we need to better characterize the amount of wind shear and turbulence in the Venusian atmosphere at altitudes that could support people. If the wind shear and turbulence are too much for big balloons to handle, Venusian colonization won't be very practical.

>>high pressure can destroy probes
every fucking thread about venus, someone thinks that pressure is destroys everything. Dealing with high pressure isn't hard. The easy way to deal with pressure is to have holes in everything so that everything is at the same pressure and there is nothing to crush. The harder way is to put stuff into pressure vessels. It's not hard to make small pressure vessels capable of withstanding this pressure. Most pressurized gas tanks can take internal pressures as high as this and it's way easier to make something that can take external pressures than internal pressures. James Cameron took a submarine to the bottom of the Mariana trench and that withstood an order of magnitude more pressure than the surface of Venus. The real problem is temperature. It's so hot that conventional silicon electronics don't work any more. But electronics based on silicon carbide are being developed which can handle the heat.

>> easy access to metals, and water in the form of Ice
not really. On mars, you have to dig for water. On venus you can extract it from the air. Plants for extracting stuff from the air are much more reliable than plants that dig stuff out of the ground.

>> using hot air balloons on venus
That's the dumbest thing I've ever read on /sci/. Venus' atmosphere is CO2, meaning breathable air is a lifting gas. One can also use hydrogen as a lifting because the atmosphere won't react with it.

Solar is really awesome on venus You're closer to the sun so insolation is greater, but the other thing is the cloud layer is VERY reflective so you can get almost twice the power per unit area by point solar cells down. Pic related is what the venusian clouds could look like, notice how bright things are. You also get a reasonable day night cycle due to the fast rotation of the atmosphere

Plastics don't rust. You can make plastics from the atmosphere. The overall concentration of water in the atmosphere is very low, but there are local concentrations in the form of clouds
