Colonizing Venus
Think we could do it before Mars? If so, what would we need to do it?
EDIT 1: We're Trending, also. You do know we are capable of filtering out sulfuric acid? Also, The Planets Magnetic Field can be stabilized with giant magnets in its polls. After stabilizing that, we are able to keep water on the planet. So plants can begin to be able to be produced there, within a few decades there will be enough oxygen for a small colony to live. The runaway greenhouse affect would probably be reduced by the other things being done in the atmosphere. I don't know exactly what can be done about its pressure, maybe the pressure would get lighter than it is, close to earth's. I'm pretty sure we're able to terraform, so land wouldn't be a problem

Unless we can invent a lightweight alloy that can withstand the atmospheric pressure for more than a few hours, probably not

2 RepliesThe gravity on venus can liquidize lead, so probably not.
-
3 RepliesWe'd be crushed by the gravity itself mars would be easier.
-
5 RepliesWe'll make Utah livable before we ever colonize Venus.
-
2 RepliesMars would be easier because there aren't insane weather conditions there.
-
Terraforming Venus would be a waste of time and resources. Venus exists just outside the inner radius of our star's habitable zone, which is only going to widen over time.

12 RepliesHere's the rant I had a few months ago. This answers your question exactly. [quote]Although I've already posted here, here' something else. Some crazy feminazi was super angry that we found water on Mars and said the discovery was sexist. She claimed that it was sexist that we found water on Mars, the masculine planet, when we could be doing the same on Venus, the feminine planet. There is a long list of reasons we can't find, and didn't look for, water on Venus. 1) Atmosphere is almost completely carbon dioxide. 96 percent carbon dioxide in fact. This comes in again later but it also doesn't help a few things. The only oxygen in the Venetian atmosphere is in the 20ppm of water vapor. That means one out of every 50000 parts of the atmosphere is water vapor. Yea, that's bad. Earth's atmosphere is ~20% oxygen in any given space, so let's compare that percentage to the percentage of oxygen in the same area from everest's peak. At the peak of Mount Everest, you have 33% of the ~20% oxygen at sea level. This means that the air at the top of Mount Everest is ~6.6% oxygen in the same area due to the fact that the air at the peak is much thinner at everest's peak than at sea level. People have to bring bottled oxygen up there or they lose proper judgment or pass out. That's with 6.6% oxygen in the same area. Venus has .00002% oxygen in the same area. Not surviving, and no water. 2) Acid rain. Before people say we can just make a ship or use space suits, we can't. Venus has acid rain, and it is extremely corrosive. Nearly every time we've sent probes we've lost contact in about 30 minutes of them entering the atmosphere because the acid rain destroys them. One landed successfully, but it transmitted for only 20 minutes before going dark. Enough said there. 3) It's F***ING HOT and the barometric pressure is stupidly high. Basically, if you were to go outside right now and feel the air push down on you, we can say that is about average for earth. Multiply that feeling by 92. Venus's atmosphere is x92 heavier than earth's. But for those not scientifically inclined, let me explain how hot it is on Venus. Because the atmosphere is almost entirely carbon dioxide, heat gets stuck there. A lot of heat. Earth's surface temp averages at 287K, which is about 57 degrees fahrenheit and about 14 degrees Celsius. Venus's average surface temp is about 735K, which is 863 degrees fahrenheit and about 462 degrees Celsius. Yea, it's hotter than the surface of mercury people and Mercury is right next to the sun. So yea, I'd say there's no water on Venus. Scientists proved it in the 70s and man can't bring water to Venus and not die. Venus cannot support life. So the feminazis can shut up and stop asking me about it.[/quote]

The only way to inhabit Venus is to have floating "cloud" cities above the atmosphere. With our current, or conceivable technology, we won't be able to alter its atmosphere noticeably. http://www.space.com/29140-venus-airship-cloud-cities-incredible-technology.html

Impossible right now, alone the rays emitted from the sun would kill us even in a suit. Venus also believe it or not rains methane periodically which I bet you can imagine is not very ecosystem friendly.

Neptune is pretty neat.

5 Repliesvenus is the asshole of the solar system its hot as -blam!-, and is holding in a punch of nasty shit at high pressures. mars is the unmotivated brother in the solar system. it has water, oxygen, co2, just needs magnetic field and filler gas for atmosphere however....were it so easy
-
We would need to learn to survive without oxygen in an atmosphere pretty much made of poison and find away to survive on a planet with an average temperature of 850 degrees.
-
Well first wed probably have to reverse the greenhouse effect they got going on to lower the temperature and solve the whole acid rain thing. Then we need to figure out how to make the atmosphere breathable. At least with Mars we only have to solve the breathing thing.
-
Humanity as a species would need to have developed advanced spacecraft capable of relatively fast travel between planets, along with the technological capabilities to terraform a planet's surface in order for the colonisation of a hostile world such as Venus - between the acid rain and the heat, even the strongest craft would not last indefinitely.
-
Maybe we could make a colony in orbit of Venus but not in it because the atmosphere is so dense it would crush the colonists

Edited by Trestero: 11/15/2016 7:41:36 AMI don't know about before Mars, but I think there were ideas on how to mess with Venus' atmosphere or work around it. If we had a good way to do it, Venus might even be better than Mars for expansion due to not having such a weak magnetic field. Essentially the biggest issue would be dealing with sulfuric acid and extreme temperatures, and we'd need to find a way to either take advantage of the state of Venus' atmosphere for our uses or cut it down somehow to something more suitable to human life (which would likely also help the temperature issue). Venus also has an issue in the form of incredibly powerful winds that we'd have to somehow account for or neutralize. I do think that by the time we can have legitimate, large-scale Mars colonization we'll probably be looking at Venus next. Not sure about whose lifetimes that would happen in, though.
