[@ianmeade7441]

@Dimitrius Didimitrius learning definitely isn't one of its intentions, because "it" is a series of *natural* processes. Here's what turned Venus into what it is today: Being both very massive, and closer to the sun meant that the Venusian never cooled sufficiently to become brittle, and so never broke into pieces to form plate tectonics. This meant that Venus never developed a constant stream of tectonic vocanoes like Earth did, and so never had a constant way of relieving pressure from the mantle. Instead, Venus just allowed millions of years worth of pressure to build up before realeasing it all as a global eruption of hotspot volcanoes. Then the mantle would re-solidify, and the cycle would begin anew. This is why Venus became a broiling hellhole. Here's what turned Mars into what it is today: Mars wasn't massive enough to sustain a fully molten, convective interior for more than a billion years after it formed. After it began cooling, there was no longer a convection of molten iron to produce a strong magnetic field, which left its atmosphere vulerable to solar wind. Over the 3 billion years since this happened almost all of the Martain atmosphere has been ionized into space, which means that it no longer has the pressure to support large bodies of liquid water, or the greenhouse effect to keep its surface warm at that distance from the sun. This why Mars became a frozen, airless rock. It's really not that mysterious.

[@BobDiaz123]

The maximum clock speed of microprocessors is limited by the maximum heat they can withstand. The higher the clock speed, the more heat is generated. If we can develop ICs that can easily operate at very high temperatures, we can get around the current temperature roadblock of the maximum clock speed.

[@magearamil8626]

But the higher temperature the higher electirc resistance which gegenrates more heat.... So essentially 500°C processor would have such high resistance thar it would work but have trash clock speed compared to normal circuit at 80°C

[@BobDiaz123]

Mage Aramil While most materials have a positive temperature coefficient, the amount the resistance rises per degree C varies from one material to another. Gallium nitrate has been proposed as one such material for a high temperature semiconductor, but in the end we might pick another material with better properties. The resistance is likely to be very small because we'll be dealing with components in the under 10nM size or even smaller. Current CMOS technology uses very little current at 0 Hz, and as the clock speed increases, the current draw also increases. The maximum clock speed is limited by silicon's ability to handle the heat. Too high a clock speed and the chip melts. High temperature semiconductors should be able to allow for a higher clock speed, but how much higher is unknown, because we don't have them working yet.

[@epiendless1128]

That 15V power supply and sounds like a problem too. We reduced the voltage in silicon semiconductors not just to reduce power (proportional to V-squared) bit also to reduce the electric stress (volts per metre) across tiny circuit features.

[@BobDiaz123]

Epi Endless Because we don't have the high temperature ICs, the discussion becomes hypothetical. The higher voltage may not be required at the 10nM level. For example the typical 350V power supply isn't required when vacuum tubes are reduced to the microscopic size. I recall that the voltage dropped to just 10V. I'll admit that because we haven't built high temperature ICs, we just don't know how far we can push them or ever if it's possible. However, it the laws of physics allow for it, the door is open to some interesting future developments.

Someone once said, the main obsession with Mars, is due to "Terrainism". An obsession to land on a new type of surface, like it was a conquest. Since it's very hard to land humans on Venus, in Mars is more possible. The same happened to the Apollo 10 mission, that orbit the Moon, but people remember more the Apollo 11 mission that landed on the surface.

[@Andrew-13579]

I think the Earth-like pictures from Mars are inviting. The thinness of the air and very cold temperatures are not realized by most. It wouldn’t matter if Mars’ air was made of 50% Oxygen and 50% Nitrogen, it would still be too thin and too cold.

[@akizeta]

Not so much. Apollo 10 was always part of the plan to land on the Moon, a goal that was established by Kennedy in the early 1960s. The idea of Apollo 10 was to test everything in Apollo _except_ the landing, to ensure that everything would work right. It wasn't a case of "Now we've orbited the Moon, I guess we might as well land."

[@kaorumugen991]

I mean... I agree with your core point, but I don't think it has anything to with "conquest" or an "obsession with landing". Obviously a reachable and stable surface to build and settle on is preferable if we're talking about (very) long-term goals like colonization and terraforming. Sure, we could have floating settlements in Venus' atmosphere, but the prospect of living on a floating platform that could fall into acid at any time isn't exactly a compelling proposition, and getting 99.999999999% of the way there with no way to push to that 100% (and no real point in doing so) is somewhat demoralizing.

Silicon is an element. Silicone is a silicon-oxygen compound known for it's rubbery properties. And when people say "silicone oil" they're simply being wrong. Silicon oils are synthetic oils where carbon has been replaced with silicon, but the hydrogen atoms are arranged the same way as in hydrocarbon oils.

[@RazzUK]

Thank you! I'm just a victim of an aggressive autocorrect however

[@adaeptzulander2928]

I can answer that. The big key with silicon is that it maintains its electrical properties (resistance, inductance, etc.) over a very wide range of temperatures. Other materials like gallium or gallium-arsenide can work, BUT their electrical properties are VERY temperature dependent. That means the electronics would have to be carefully temperature controlled. Imagine a PC or phone that works well indoors, but fails when taken outside on a sunny day or winter day.

@Anton SiC is in quite widespread use for high power electronics. Though for low power and logic circuits it is not really interesting compared to silicon. As you pointed out they have to run at a higher voltage, which is due to the higher forward voltage of SiC compered to silicon. But since transistors and diodes made of SiC can have lower resistance when switched on they do offer efficiency advantages when run at high volts. This is why there are transistors and diodes based on SiC but scarcely any integrated circuits.

The simplest data, the location, is obtained by adding a corner-cube RF reflector. Putting reflectors on the drive fan tips lets the fan rotation be measured remotely, much like a non-contact tachometer. It is possible to also vary to polarization of the reflection, permitting continuous values such as temperature from a simple bi-metal strip (like in cheap thermometers) to be sent purely by mechanical means, where the bimetal strip would direcctly change the characteristics of the reflection element. The radar pulse itself can also be moved in frequency, phase and polarization, making it possible to get many readings in a single pass, perhaps even read each multiple times. The return signal strength depends on the size of the reflector, so it may be the case that either the robot would need to be quite large, or the reflectors must unfold upon landing.

The perfect place to test potential rover designs would be active volcanoes.

[@mikedrop4421]

You mean under one.. Remember ground level is 98 times higher pressure than earth.

[@colleenforrest7936]

Just saw a video from a drone that flew into an active volcano in Iceland. It didn't last long. But what if we had sensors that did?

[@Mr.Nichan]

They often get a lot hotter than Venus. Venus is colder than lava, although a lot of lava is colder than that ~1000°C limit he mentioned for SiC, and continental volcanoes tend to have colder lavas.

[@Mr.Nichan]

@@mikedrop4421 My rough estimates put that pressure less than 500m down below solid or liquid rock. Just FYI. I doubt the pressure would be a fundamental problem though. Magma or geothermal fluids (like volcanic gas) mights chemically attack the electronics (e.g., H2O breaks down SiC into SiO2 and CH4 at high temperatures and pressures, and things can dissolve (certainly SiO2 in magma)), but you could seal them in a protective container, and pressure might crush some things built at atmospheric pressure if you didn't take it into consideration, but 100 bar is not enough to directly damage solids the electronics are likely to be made of, at least not if hydrostatic (equal on all sides).

[@mikedrop4421]

@@Mr.Nichan That's the point.. Being that the atmosphere is Co2 and Sulfuric Acid as such high density and pressure you have to completely seal the electronics or they're going to corrode and dissolve. So it not necessarily that the solid state circuitry can't handle the pressure it's that the entire system has to be sealed against such pressure or the electronics will fail and at 470c electronics will be melting without cooling systems that also have to cope with the pressure.

Computers are switches. Relays are switches. Make some very high temp relays and do ladder logic to do various functions and possibly function as a crude telegraph type radio. Make wire out of 600 Nickel. Aerojel and Fiberglass or Ceramic fiber work well as insulators. Plenty of other things as well.

[@maxhunter3574]

Isn't the atmosphere of Venus also very acidic too? Or did I remember that incorrectly?

[@kirowilber9121]

There is a Haze layer of sulfuric acid, and then straight up Clouds of Sulfuric Acid about over Troposphere, and below the Stratosphere

[@mamaluigi56649]

That is correct

[@tonydai782]

It has clouds made from sulphuric acid

[@kineticstar]

The atmospheric acidity is not the worst thing to over come on Venus. It is the ever present crushing pressure and the literal hellish temperature. Those two things would stress and fatigue any metal on their own and together they are billion dollar exploration killers. The acid can me combated by a simple plastics.

[@excitedbox5705]

SiC chips are actually mainstream already. They are mostly used for power chips because that is where you get a benefit here on earth. GAN and GIN are other materials used for high temp power chips because of the fast switching frequency they are much more efficient. There is a ton of work happening in advanced ceramics right now.

[@alihms]

Even though you may be able to delay the eventual outside heat from coming in, it still won't work. Normal IC using regular silicon will generate heat internally and they operate optimally below 90°C. This heat has to transferred outside to prevent overheating. You can't build a cooling system to transfer that 90°C heat out to an environment which has an ambient temperature of 500°C. Basic thermodynamics prevents that. Heat 'flows' from hotter to cooler, not the other way around.

For anyone excited about consumer electronics made with Silicon Carbide, note he said they are a lot less efficient. Wherever you don't expect to have to reliably face temperatures well above 110C you are way, way, better off with conventional silicon. It runs much efficiently and thus way faster for less power. Now, the fact you can get any type of working electronics in Venus, or deep within the crust, is absolutely amazing. So yeah, not a silver bullet people, but amazing for what it is, a way into new environments we couldn't make "smart" before.

Even if not, vacuum tubes should still be possible. In the extreme case, you would just need active cooling for part.

[@brunoethier896]

@@absalomdraconis Unfortunately, vacuum tube have the same problem with heat, and "active cooling" only means that you move heat from a hotter part to a less hot part (ie, inside to outside, like a fridge) but on Venus the outside temperature being 800C, it becomes impossible to do that.
