I don't see it as a beautiful thing... I see it as a sad thing... Like the planet is in agonizing pain and continuously bleeding ferociously, by squashed, suffocated and burnt by it's own self... The planet is trying to reform but keeps cracking and bleeding over again... It's just really sad... Yes i know is the biased knowledge of the possibility that it could've been once just like our earth is what is causing me to feel that way, but mars is slso given that speculation too and it doesn't seem to be in pain like venus, mars is a cold and dead corpse in comparison, saved from the torture venus is facing...

In that book, they speculated that Venus was probably a lush, green, tropical paradise. They also mentioned the canals of Mars. This same set of books also covered dinosaurs, where they discussed the Brontosaurus, saying that its brain was so tiny that it barely knew it was alive. Oh boy, the things we didn't know back then!

I didn't realize this as a kid but I was basically learning at the same time everybody else was what the outer planets were really like. I always wanted to be an astronaut. But there were always these dreams that people lived on Mars and Venus because we didn't know for sure what were on those planets, and the textbooks said dinosaurs could still exist somewhere on Earth or deep inside hollow Earth, and that Neanderthals and cavemen were stupid.

The answer is - not cheaper, but that USSR and USA both were sinking HUGE amounts of money into space missions; their respective space exploration groups got money equal to the entire military budget for a while there. They operate now on a relative shoe string budget, making the Rovers just as incredible for achieving so much and such longevity on a fraction of the money and time invested.

Venera went silent because it was probably being slowly boiled into molten metal slag by the Venusian high temperature, or it was being slowly crushed like a beer can by the high Venusian atmospheric pressure. One or both outcomes could have happened as Venera was transmitting data and images of the planet to Earth.

[@louisvictor3473]

Venus is not hot enough to melt the metals used, not many a reason to use unalloyed tin or lead, which are the sorts of low melting point metals that would melt at just under 500C. The heat generating electronics though, this is hot enough to make them cease functioin properly, possibly melt the mental in the electronics, but still that would hardly classify the entiee problem as molteb metal by now. Temperature might also weaken the materials enough so that temperature wins and the outter shell implodes due to pressure.

It seems to me the most likely failure point was either the electronics overheating as #1 or solder melting as #2.

I think my favorite imaginary possibility is the "floating life band" notion: that life might exist in a relatively narrow band within the atmosphere, a "sweet spot" that isn't too hot, too cold, OR too acidic. Someone had an illustration of flying cities even, habitats like immense bubbles that would be buoyant in the upper atmosphere, mining the clouds for various compounds. People could live in such places, protected from the sulfuric acid. Though exactly what valuable compounds would justify such a huge undertaking is where that idea breaks, haha!

Mercury is between minus 180c and plus 430c. The lack of atmosphere is what makes it impossible for it to keep the heat it gains. Opposite reason Venus is so Hot.

[@flat6croc]

Actually, the amount of energy from the sun per square meter on Venus in only double that of Earth - it's not like it's 100 times. For Mercury, it's seven times more energy. A lot in some ways, but not hundreds or thousands of times more energy.

I still remember in elementary school, we were looking at the only pictures available of Venus's surface at the time, and the teacher told us that the reason was because Venus's atmosphere is just too hazardous even for NASA's devices. The equipment that was sent to Venus was said to have been struck by lightning and destroyed before getting a quick picture to send back, which made all of the kids start theorizing how to mitigate the lightning strikes for future missions. The most popular "brilliant" idea that the kids insisted would work was making the space shuttle and rovers out of rubber somehow, because rubber doesn't conduct electricity as well as most metals do. Obviously, the teacher knew this wouldn't work irl, but she struggled to explain _why_ it wouldn't actually work. Still, it was a very memorable class, and it's why I still remember why we know so little about Venus and struggle to learn more.

[@ZadesLegacy]

Electricity will flow through anything if with enough voltage. Lighting's existence is proof. Just need enough voltage (pressure) and you can push it even through rubber. This is a crude explanation. But I always find it fascinating. We don't understand electricity as much as many people think we do.

There's a sci-fi concept I always liked. In the videogame Mass Effect there are a race of creatures called the Krogan. They are by their nature very war-like and aggressive and their society is based highly on dominance and reputation. Their home world Tuchanka is placed in a similar location in it's solar system as Earth is in ours, and like in our solar system, their home system also has a 'Venusian' hothouse-type planet closer in orbit to their star. The Krogan acquired space travel at some point, and then started a ritual tradition of proving manhood amongst the Krogan. What they would do is travel by spacecraft to the 'Venus-type' planet in their solar system and attempt a landing, in person. The Krogan male would land on the surface of a planet that had an atmosphere that was 90x our atmospheric pressure, mostly made of CO2, and 400C temp. Most Krogan would die in the attempt. But, there were a number of Krogan men that would survive and return, and those individuals were revered for the rest of their lives. EDIT: The Krogan were basically humanoid in shape (head, torso, 4 limbs) but they were 300kg, muscle-bound tanks that had 2 hearts and three lungs and were tough as hell., so scientifically, that's how it was plausible that they survived this ordeal. If a human tried this, they'd die almost instantly. Krogan are built different.

Too fantastic to exist. But then, the first time I looked through an actual telescope I saw both Venus and Saturn and it was a life changing moment. Things that were just ideas or concepts or fantasy laid right before my eyes. It was both awe inspiring and, in some ways, frightening. They were actually real and how it changed my world.

I would say Apollo and the moon landings were more so. And the vertically landing rockets of now simply would not have been possible back then. Microcomputing is probably more so. Sending a craft to deviate something as relatively tiny as an asteroid is astonishing.

@@Djolee4 The point of going to the moon was because you can exist on its surface. We couldn't get to Mars and no other planet can be landed on by people. The reason we are going back to the moon is primarily to test surface systems for the Mars expedition.

Venus is easily one of my favourite planets of the Solar System. I really hope we get to see more missions touching the surface and staying for a long time... maybe even a rover! Wish I could see that surface with my own eyes, even though I'd be rushing back to the lander real quick xD

[@emuhill]

Long term missions let alone a rover are not very practical with current technology. You would have to find a way to keep what ever you send on Venus's surface from melting from the extreme heat for an extended period of time. All of the probes that landed on Venus in the past were only capable of doing that for about 2 hours max.

[@Alpharius93]

@@emuhill There's actually been quite a lot of useful development in this regard recently. I can't quote it right now, but NASA had published some successful work on high-temperature processors and they had a mission concept for an "automaton" rover that is as simple as possible to minimise points of failure. Essentially: robotics for high temperature and acidic conditions are hard to make, but general machinery is easy and there is much experience on it already.

[@BierBart12]

It's so good to finally hear about this project after finding out about it years ago and not finding much discussion, or any generally used educational material, despite how SIGNIFICANT it was. 12:39 This image reminds me so much of the broken data spheres(I forgot what they were, it's been a while) in No Man's Sky. But I'd never forget what they *looked* like. The strings from the parachute were wires going into the ground, though. I wonder if there's some inspiration here.

[@robbierobinson8819]

Another excellent presentation, Alex and the Astrum team. This episode gave some really interesting insights into Venus and a desire to learn more as more probes and landers visit her. Whenever I hear and read about planets with dense atmospheres, I wonder whether this isn't where organisms would be found? Perhaps the variable records of phosphine are due to floating patches or colonies of organisms scattered at altitudes in the clouds where conditions allow them to have evolved. It seems likely that the extreme temperature and pressure ranges as well as crazy wind speed at altitude could produce all sorts of odd chemical reactions and mixing within the clouds.

[@bane2201]

Interesting point - Venus has much more reactivity than early Earth did. I wonder whether that'd be good or bad. It'd make it easier for a self-replicating molecule (life) to exist, but the odds of winds and heat destroying it are very high too (and even if it manages to reproduce, that applies to the descendants too). Depending on how small a self-replicating molecule can be, one hypothesis is that there are new "species" pretty frequently, but that they don't get very far before Venusian forces destroy them.

[@greghelton4668]

I have a hunch that a lack of a large moon and anemic rotation is what caused Venus to be so hot.

[@SuLokify]

That is a sensible hypothesis.

[@thechosenegg9340]

I've always heard people say it was greenhouse gasses in the athmosphere.

[@SuLokify]

@@thechosenegg9340 Right, that's why it's hot now, and why it's stayed hot. But why does Venus have this accumulation of gases while Earth doesn't? Earth and Venus are almost identical in size and solar radiation, the most obvious differences are the large moon, life, and length of day.

[@greghelton4668]

@@thechosenegg9340 that’s a big part of it. Earth has a mechanism to requester gases back into the mantle via tectonics. I suspect the moon has a large part to do with plate tectonics.

[@rjbiker66]

​​@@SuLokifyhow can they be equal in solar radiation when Venus is much closer to the sun. The high heat at the surface is due to high atmospheric pressure. 90 times higher than earth. Venus has a high albedo. So the actual solar radiation that reaches the surface is much lower than earth.

Carl Sagan made the first proposed method of terraforming Venus was made in 1961. In a paper titled “The Planet Venus“, he argued for the use of genetically engineered bacteria to transform the carbon in the atmosphere into organic molecules. However, these bacteria would have to be engineered to survive immense heat, pressure and acid rain. Not impossible to do, but definitely pushing biology to its limits.

[@rigierish3807]

The beginning pronunciation isn't really "uh". The "a" is more pronounced as in "far". The "i" at the end is like the letter "e" in the alphabet. For the "u" though, I don't have any equivalent, because there's no equivalent in English. But your approximation is good enough. The rest of the letters can just be pronounced as they appear.
