What do you mean by Venus floating cities?
I'm hoping to write a science fiction story about visiting Venus as part of the space race and I would love your input
Alright so the thing with Venus is that we're all very familiar with her horrible hell-death clouds and 900°F surface temperatures. We all understand the surface of Venus is not a fun place for humans to be.
But, nobody ever talks about the fact that ABOVE the hell-death clouds, Venus is a paradise. The most Earth-like environment we know of in the solar system, beyond Earth itself, is actually in the skies of Venus.
About 30 miles above the surface, the pressure is ~1 atmosphere, and the temperature ranges from 30 - 100°F, which is Happy Human™ standard pressure and temperature.
What's more, a breathable mix of oxygen and nitrogen provides over 60% the lifting power on Venus that helium does on Earth. In other words, a balloon full of human-breathable air would float to the habitable range of Venus's atmosphere. We could float a ship with the very air we breathe.
The other great thing about this is that it avoids one of the big problems with Mars colonization. On Mars, any habitat on the surface full of breathable air is vulnerable to leaks and explosive decompression, a la the Martian.
Floating on Venus, a balloon full of breathable air doesn't have a significant pressure difference between the inside and the outside. Which means, any leaks or tears would be very slow and manageable. You could fix that shit with duct tape!
Similarly, because the environment outside the balloon is so Earth-like, humans living there wouldn't need any big fancy pressurized suits for extravehicular work. We'd need air to breathe, maybe some heat protection, and protection against the acid rain. That's it.
Venus also provides the tools to keep us fed! It's atmosphere is made primarily of carbon dioxide, even above the dense horrible clouds. What likes carbon dioxide? Plants from Earth!! Lets grow FOOD on FLOATING PLATFORMS in the SKIES of VENUS.
This whole idea actually came out of a NASA effort exploring potential Venus colonization. The program was called HAVOC - the High Altitude Venus Operational Concept.
It hasn't really gone anywhere, and as far as I know there are no real plans to revisit it. Unfortunately, from a practicality standpoint, Mars is a much more viable target for human colonization. Not only is it better poised for outer solar system exploration, being farther away from the sun, but living on Venus would come with too many complicated contingencies. In the event of a major failure on Venus, you'd need to fly to another base, or fuck off all the way to orbit. I understand why people aren't really in a hurry to live somewhere where landing on the surface means certain death.
But that doesn't mean I won't be forever and always enamored by the skies of Venus. Here's one of the artist concepts to come out of HAVOC.
I want to be there.
also the acid sky sharks are a pain
There's a lot of discussion about terraforming Mars. But it doesn't have a magnetic field to sustain an atmosphere! Venus clearly has an atmosphere, so we must have a magnetic field. I've always meant to read up on any information about terraforming Venus.
Oh man it's actually weirder than that! Venus actually doesn't have a magnetic field!
Which makes the question of how it keeps its atmosphere, and how it got so large an atmosphere in the first place, a big one in the planetary science community. I did a little bit of a followup about Venus's magnetic field here.
But basically, the consensus for so long was that Earth needs a magnetic field to keep its atmosphere, and so magnetic fields are requirements for life on terrestrial planets. But Venus's existence throws a wrench in all of that and tbh I love that for her.
