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.

Student Experiments Soar!

Have you ever wondered what it takes to get a technology ready for space? The NASA TechRise Student Challenge gives middle and high school students a chance to do just that – team up with their classmates to design an original science or technology project and bring that idea to life as a payload on a suborbital vehicle.

Since March 2021, with the help of teachers and technical advisors, students across the country have dreamed up experiments with the potential to impact space exploration and collect data about our planet.

So far, more than 180 TechRise experiments have flown on suborbital vehicles that expose them to the conditions of space. Flight testing is a big step along the path of space technology development and scientific discovery.

The 2023-2024 TechRise Challenge flight tests took place this summer, with 60 student teams selected to fly their experiments on one of two commercial suborbital flight platforms: a high-altitude balloon operated by World View, or the Xodiac rocket-powered lander operated by Astrobotic. Xodiac flew over the company’s Lunar Surface Proving Ground — a test field designed to simulate the Moon’s surface — in Mojave, California, while World View’s high-altitude balloon launched out of Page, Arizona.

Here are four innovative TechRise experiments built by students and tested aboard NASA-supported flights this summer:

1. Oobleck Reaches the Skies

Oobleck, which gets its name from Dr. Seuss, is a mixture of cornstarch and water that behaves as both a liquid and a solid. Inspired by in-class science experiments, high school students at Colegio Otoqui in Bayomón, Puerto Rico, tested how Oobleck’s properties at 80,000 feet aboard a high-altitude balloon are different from those on Earth’s surface. Using sensors and the organic elements to create Oobleck, students aimed to collect data on the fluid under different conditions to determine if it could be used as a system for impact absorption.

2. Terrestrial Magnetic Field

Middle school students at Phillips Academy International Baccalaureate School in Birmingham, Alabama, tested the Earth’s magnetic field strength during the ascent, float, and descent of the high-altitude balloon. The team hypothesized the magnetic field strength decreases as the distance from Earth’s surface increases.

3. Rocket Lander Flame Experiment

To understand the impact of dust, rocks, and other materials kicked up by a rocket plume when landing on the Moon, middle school students at Cliff Valley School in Atlanta, Georgia, tested the vibrations of the Xodiac rocket-powered lander using CO2 and vibration sensors. The team also used infrared (thermal) and visual light cameras to attempt to detect the hazards produced by the rocket plume on the simulated lunar surface, which is important to ensure a safe landing.

4. Rocket Navigation

Middle and high school students at Tiospaye Topa School in LaPlant, South Dakota, developed an experiment to track motion data with the help of a GPS tracker and magnetic radar. Using data from the rocket-powered lander flight, the team will create a map of the flight path as well as the magnetic field of the terrain. The students plan to use their map to explore developing their own rocket navigation system.

The 2024-2025 TechRise Challenge is now accepting proposals for technology and science to be tested on a high-altitude balloon! Not only does TechRise offer hands-on experience in a live testing scenario, but it also provides an opportunity to learn about teamwork, project management, and other real-world skills.

“The TechRise Challenge was a truly remarkable journey for our team,” said Roshni Ismail, the team lead and educator at Cliff Valley School. “Watching them transform through the discovery of new skills, problem-solving together while being driven by the chance of flying their creation on a [rocket-powered lander] with NASA has been exhilarating. They challenged themselves to learn through trial and error and worked long hours to overcome every obstacle. We are very grateful for this opportunity.”

Are you ready to bring your experiment design to the launchpad? If you are a sixth to 12th grade student, you can make a team under the guidance of an educator and submit your experiment ideas by November 1. Get ready to create!

Now, seven months later, Gen. Mark Milley, chairman of the Joint Chiefs of Staff, tells "CBS News Sunday Morning" the balloon wasn't spying. "The intelligence community, their assessment – and it's a high-confidence assessment – [is] that there was no intelligence collection by that balloon," he said.[...]

The balloon had been headed toward Hawaii, but the winds at 60,000 feet apparently took over. "Those winds are very high," Milley said. "The particular motor on that aircraft can't go against those winds at that altitude."

Wow that almost sounds like exactly what the Chinese government (evil communists, will eat you and your babies) said on day 1 and have said ever since. Which can only mean.....

How did they know & what are they hiding 🧐🧐🧐🧐

every accusation is an admission

[ms-demeanor]

sorry if you've answered this before, and i hope you don't mind me asking, how do you know so much about computers and what seems to me like everything in the world? how did you become so knowledgeable? it's amazing

i just know a little about a lot of things and I probably have a fair number of things that I've dug into more than most people and less than people who actually focus on that stuff! It's kind of an illusion!

I do know a lot about computers and that's because I've worked at a computer company for 12 years and have been deep into a computery subculture for about 20 years - I do genuinely know a lot about consumer computers. That I'll own and that's experience.

I know a fair amount about literature because I've got a degree in it!

I know a fair amount about journalism because I've got most of a degree in it and I worked with journalists for a long time!

I know a fair amount about nutrition because I've got most of a degree in it and because I've been focused on reading a lot about nutrition for more than a decade because of my own food issues!

But mostly I'm just someone who falls down rabbitholes and has a decent ability to recall what I find when I run down them.

Also I get curious about things and will just go. Experience them.

Like at some point i came across a site for people who own and use RealDolls and I got interested in learning more. The site required an application because they didn't want people just trolling so I applied and I ended up reading through the whole site and reading the magazines they sent out for years after because it was just interesting. The way these guys bought clothes or compared repair techniques and cleaning techniques, the way they constructed identities for their dolls - it was all interesting! So now I know about the proper way to store a RealDoll and how their skeletons are put together and the best way to prevent rips or clean inserts.

Now imagine that with everything.

I got interested in quack medicine so I ended up reading the entire back catalogs of quackwatch and science-based medicine.

I got interested in the history of aspartame as a scare-word and I ended up reading a couple of books, SEVERAL entire blogs with decades-long runs, purchasing a military magazine from the 90s, and submitting a FOIA request.

But, like. I don't own a RealDoll or work in that industry. I am not a medical professional. I am not a chemist who works with aspartame. So I get these weird little collections of information where I know what *seems* like a lot to someone who hasn't looked into it but I know a lot less than someone who has taken the time to actually dedicate themselves to that topic.

And sometimes it's a years-long dive and sometimes it's a months-long dive and sometimes it's a few hours of me digging online until I feel satisfied with what I've learned and I never come back to it, but I've got three more talking points than your average joe at a party would.

(Also though I've attended various colleges at various levels for ten-ish years now and I've taken probably more college-level classes on a lot of subjects than most people have because I've now spent several years just kind of kicking around at community colleges and deciding that a cartooning class sounds fun or that a mesoamerican art class fills certain transfer requirements or that I might as well brush up on spanish, french, and german. Access to low-cost college classes in california is a big part of this, and having the time and money to take classes while i'm working is something that I've been very lucky with)

I've also worked pretty much continuously since I was 18, sometimes holding multiple jobs at once, and I know a lot of interesting people who do a lot of interesting things and I ask them about their interesting experiences and if they offer me a chance to go do cool shit with them, like launch a high altitude balloon or blow up some dynamite that's about to expire or join a band, I do it!

I was also one of those kids who had no friends and spent too much time at the library so I'd do things like read through medical textbooks or pull a book of home chemical formulas out of the trash and read it or take it into my head that I was going to read all of Shakespeare before I got to high school so I was a really annoying twelve-year-old and that kind of thing never really let up.

I don't know! I don't think it's that unusual and I think most people do this kind of thing I just happen to have less focus than a lot of people and talk a lot more.

The Satellite Rank in a World With No Space Travel

I’ve wondered for a while about the reason the word “satellite” is used in the RCM to describe a rank when, apparently, space exploration or travel is impossible in Elysium due to the pale. I love the meta’s, fics, art, that uses a space motif for Jean as much as the next guy, but, canonically, there are no space stations, no satellite tvs. It’s unclear even how much awareness Elysium’s population has of other planets, of the motion of moons… they talk sometimes about stars or naval navigation… (I could write a whole post just about how the lack of modern astronomy knowledge would affect language, metaphors, art in the world of Elysium… the implications are fascinating.)

Where, then, is the term satellite coming from? Even if in 52’ they are starting to work on sending high altitude balloons or prototype satellites up, the RCM has apparently been using the term “Satellite” for a long while.

Maybe everyone else already knew this, but I’d never known that the word satellite had an established definition in english well before it was used to describe celestial phenomena.

The term originally comes from the latin “satellit, satelles” meaning “escort or attendent”. Webster gives us the definition, “one who escorts or follows after an important person.” From the Lewis and Charles latin dictionary we get “A lifeguard,” “an accomplice.” My french is rusty, but from the Dictionnaire illustré latin-français we are given “les courtisans,” “compagnon ou compagne,” “serviteur.” A courtisan, a wife or girlfriend, a servant or domestic respectively.

To double down etymologically, the word satellus (simply another form of the word satellit) is literally the diminutive of the word satḗr, meaning “the possessor”. I.e. satellus would mean “the possessed.”

In latin the word satellit was often used to name the followers or worshipers of a deity. If we dig back a bit further, we come to the Proto-Indo-European “Tek-” meaning, “to take by the hand” or “to receive.” The greek words stemming from this same root include the word for “possession,” “property,” “a domestic animal,” “live stock,” “taking, holding, keeping something as one’s own.”

Our astronomical use of the word satellite is actually a metaphor based on the earlier definition—ie the moon “escorts” and “attends” to the earth. The earth owns and possesses the moon. I’d always assumed the metaphor ran the other way, so to speak.

So in Elysium, a world in which the astronomical definition of the word satellite has not eclipsed the original connotation of the word, the rank of Satellite Officer might carry far heavier implications and associations than we’d at first assume.
