Recommended by Ricochet Members Created with Sketch. Raining in the Solar System

 

Venus lightning and clouds
Lightning and clouds on Venus – an artist’s impression.
Earth is not the only place in the solar system where it rains.

Venus takes acid rain to a new level. In the clouds of Venus, it rains pure sulfuric acid, which is better known for being in your car battery. NASA probes have also confirmed the presence of lightning – not surprising, given just how thick the clouds are. Not to worry, though, the rain doesn’t actually reach the surface, which has such insane heat and pressure that the battery acid rain evaporates before hitting the surface. The surface of Venus is a volcanic hellscape (you could have pools of molten lead, and the carbon dioxide atmosphere becomes a hybrid of liquid and gas called a super-critical fluid), so the acid rain is the least of your concerns.

It says something for how hostile colonization is off of Earth that the atmosphere of Venus (50 km above the hellish surface) is seriously being considered for colonization. It helps that the CO2 atmosphere is so dense that the nitrogen/oxygen mix in our atmosphere would act like helium in a blimp. That high up, you would only need a hazmat suit, as opposed to a spacesuit, and we have a lot of experience making acid-resistant clothing.

Methane Rainstorm on Titan
Methane Rainstorm on Titan – Artist’s Impression by David Hardy https://www.astroart.org/saturn

On the other side of the thermometer, you have Titan. Titan is one of the moons that just inspires wonder. It has a frigid, mostly nitrogen atmosphere, with a temperature around the freezing point of methane (the main component of natural gas). This results in a planet where methane acts in all the ways water does on Earth. There are methane lakes, methane clouds, and methane rain – which falls slowly due to the low gravity. On the other hand, Titan’s water acts like silica on Earth. There are vast sand-dunes of water ice, and thick layers of solid ice over water, with the occasional water volcano.

Did I mention that because of the low gravity and dense atmosphere of Titan, a person could strap on wings and fly like a bird? Needless to say, Titan is on the colonization radar. It’s currently my favorite moon in the solar system.

    All the destinations sound just lovely. I can’t make up my mind.

    Colonize Venus? I’ve always thought that Venus would be a good place to send our garbage for incineration.

    I’d love to see it rain cats and dogs on another planet or planet-sized moon.

    This is part of this month’s group writing series Raining Cats and Dogs. We still need plenty of entries, so feel free to add more!

    So, Venus would be the destination hotspot for Earth’s snowbirds? Just like Arizona, but without all the crowds?

    The Sun is a bigger, easier target for that.

    Venus colonization might be something like this:

    Venus Colonies floating in the clouds
    Venus Aerostat Colonies floating in the clouds.

    This made me think of the few landers that have been sent to Venus. I wondered which one lasted the longest and for how long. It was the USSR’s Venera 13, which lasted for 127 minutes. The article mentions that NASA and Russia are discussing a successor mission to last months on the surface. Seems ambitious to go from 2 hours to months in one leap.

    I enjoyed Imperial Earth as a teenager. Released in 1976 for the bicentennial, it is set in 2276 and Titan has a colony of a quarter million people.

    Yeah, but I didn’t want to mess with it being necessary for all life, etc..

    Venus colonization might be something like this:

    Venus Colonies floating in the cloudsVenus Aerostat Colonies floating in the clouds.

    That would be quite spectacular, provided we could see below the clouds.

    Video gamers sometimes employ a cheat called “god mode” that grants the player complete invulnerability. Conditions and creatures which provoke fear under normal circumstances become more pleasant when they no longer threaten. 

    Here on Earth, this is a common effect of photographic distance. We marvel at so many beautiful scenes through pictures and videos because our bodies are not then oppressed by those environments’ heat or cold, the mosquitoes or ants, traffic noise, bothersome people, etc. Photography enables us to isolate the elements we prefer. 

    I occasionally play space exploration games. They barely scratch the surface of our galaxy’s wonders. But we are gradually developing ways to simulate safe exploration of other planetary environments. One can already pop on a VR headset and look around Mars as recorded by NASA’s rover.

    I thought Outland was set on Titan but it turns out it was set on Io. It was High Noon in space. I have always enjoyed some of the newer sci-fi movies and shows where people are just doing regular blue collar stuff in space, like Yaphet Kotto and Harry Dean Stanton as space snipes in Alien, arguing about overtime.

    When I first heard about this, I was incredulous, but it does seem that putting an outpost on Venus would be one of the easier options.

    That said, I think it would be prohibitively difficult to turn that outpost into a colony. All space colonization suffers from some form of “and what do these people do once they’re there” but Venus — lacking water and solid material where the colonies would be — seems intractable that way.

    On top of that, you’ve got a relatively big gravity well of its own, making transportation off-world is going to be costly.

    My thought on a Venus colony is remotely operating mining via telepresence. Probably only profitable for precious metals, but it is easier to control the machines if they have only a little light lag.

    Unless there’s something really astoundingly awesome on the surface, I doubt that would be economical (or practical).

    The Delta V required to get from Venus’s surface to orbit is nearly three times what it takes to get into low-earth orbit. This is due to the awful atmosphere more than anything.

    If we want to expand our presence in the solar system, planets probably aren’t the way to go. Mine the asteroids for material and build lots of big space stations.

We marvel at so many beautiful scenes through pictures and videos because our bodies are not then oppressed by those environments’ heat or cold, the mosquitoes or ants, traffic noise, bothersome people, etc. Photography enables us to isolate the elements we prefer. 

    Colonizing Mars is science fiction. Low gravity would wreck human bodies, if not as quickly as duty on the ISS. They’d need constant protection from radiation. Micrometeorite strikes would be frequent enough to occasionally wipe out key structures or people. “Colonists” would have nothing to do but build mines and constantly shore them up to keep the (manufactured) air in.

    Humans on Venus is past the science fiction shelf – keep going into the fantasy fan-fic section. 

    Mining on the Moon and asteroids is our likeliest next successful step. Mining operations will be set up by humans, at least at first, but run robotically. The key step required to enable that future is a cheap way in and out of Earth’s gravity well.

    I believe the jury is still out on Martian gravity being low enough to cause the same effects as weightlessness. Also, I believe most of the colony ideas are at least partly buried structures to deal with micrometeorites.

    Humans on Venus’s surface is silly. The upper atmosphere actually provides good protection against all of the hazards listed for Mars, in exchange for requiring a corrosion-resistant station. (Teflon, anyone?)

    The point of the space colony is to work toward redundancy. If Earth is rendered uninhabitable, we are screwed – unless we have colonies elsewhere.
