ESA to Send Spacecraft to Venus

teeto writes to tell us The International Herald Tribune is reporting that the European Space Agency is planning to send a spacecraft to peer at Venus." From the article: "If the robot craft pulls off the complex maneuver of slowing down enough to swing into orbit, scientists hope it will help solve the mystery of how the shrouded, churning atmosphere of Venus formed and how it maintains the planet's broiler-like temperatures."

    I've been reading Slashdot for years and while there's always a ton of comments in the Mars articles about how great it would be terraform that planet, no one ever mentions doing so to Venus.

    Why??

    I look at the gravity situation and I really can't understand why people focus on Mars. Really. Does anyone ever look at the surface gravity of Mars before they start talking about terraforming it? It's only 38% of Earth's! (Compare that with freaking Mercury at 28%, or even the Moon at about 17%. ) What are your bones going to be doing in that environment after a few years?

    But take a look at the surface gravity on Venus: it's 90% of Earth's.

    Sure, you've got atmospheric pressures at the surface 90 times greater than on Earth. And the temperature averages 460 degrees Celsius. The atmosphere is about 96% carbon dioxide, and about 3% nitrogen. Then you've got trace amounts of sulfuric acid (tasty!), chlorine, and fluorine.

    But seriously ... why, after comparing the two planets, do people focus on Mars? I'm asking an honest question. From my perspective, Mars has so little to work with. Venus has plenty -- too much in fact. But think about it. Humans have proven themselves pretty good at destroying atmospheres. They're not so good at creating them. And in the case of Mars, you need to create an atmosphere. But in the case of Venus, you need to destroy it. Doesn't this make Venus a more natural candidate for human endeavours?

    Surely there's a chance that, with our slowly evolving understanding of organisms that survive around deep-sea volcanic vents, and our ever-evolving ability to tweak natural organisms, that we could devise some kind of bacteria that could thrive on Venus and start capturing the carbon from the atmosphere. There's so much for it to work with there. All that tasty carbon dioxide! And hey, H2SO4 ... can't you get water out of that somehow? Crank things up with some additional hardware, and if you pull enough material out of the atmosphere, you start to reduce surface pressure.

    And then there's that beautiful surface gravity.

    Have I mentioned the surface gravity and how it's so close to that found here on Earth, unlike Mars?

    I'm sure plenty of people far smarter than I ever will be have considered Venus and dismissed the idea after a few seconds of thought. But why? And why is Mars, with such wimpy gravity and such a scarce existing atmosphere given all the attention when it comes to dreams of terraforming?

The lower gravity also makes it easier to have a space faring civilisation there, and you have easy access to the asteroids.

You'd probably need to make it mostly 02, with a lower total pressure than one atmosphere, in order to be breathable, and at a livable temperature.

      You make a good argument, but I'd like to add a qualification. I'm not sure the availability of energy itself is a problem with Venus. More than enough energy for any conceivable terraforming rains down on Venus from the Sun. And it's quite usable energy, since its temperature is close to that of the solar photosphere (5500K). Thermodynamically speaking, you can run some very efficient heat engines between a hot reservoir at 5500K and a cold reservoir at even the high temperatures of Venus (300-700K, depending on altitude).

      So the energy is there. But it isn't necessarily easy to use. The only plausible scenario probably remains some kind of biological seeding, i.e. designing some kind of photosynthesizing microbial life that can suck up all that CO2 and convert it to carbonate rock, as such life is thought to have done in the early history of the Earth, which is where our CO2 went and why we have great beds of limestone in the crust.

      But I believe the problem with this is that there is very little water in the Venusian atmosphere, and all the microbial life we know about needs water.

    The reason for needing this kind of effort to cool the Space Station, even thought it's in the "very cold" environment of space, is that while the temperature of space is very low, the thermal capacity of space is also very low. That is, there's just very, very little of any cold matter around to which you can transfer heat, the way your body transfers heat to winter air when you step outside in December. You can radiate heat as infrared radiation, of course, but to be efficient this requires a lot of surface area for the volume being cooled.

      One good measure is the thermodynamic efficiency. This is the maximum theoretical fraction of a given amount of heat that can be converted to useful work, and it's just given by 1 - Tc/Th, where Th is the temperature of your source of heat and Tc is the temperature of your sink (where the heat goes). You can see that if you have no temperature difference at all (Tc == Th) you get an efficiency of zero, and if you have either an infinitely hot heat source (Th -> inf) or an infinitely cold heat sink (Tc -> 0) you get perfect efficiency and can transform heat to work perfectly. Reality is, of course, in between.

      Incidentally, the reason you need both a heat source and a heat sink is that it is the flow of heat that you can tap to do work, like you can sink a waterwheel into a rushing stream, or like you can put a lamp or other electrical device into a flow of electrons.

      It's not quite the quality of the heat per se that matters, then, but the quality of the heat flow, captured in the difference in temperature. It's like the drop in water height that you tap for a hydroelectric plant, or a voltage drop across a battery -- the larger the drop, the better.

      It's been a little while since my physical chemistry classes, but the wikipedia explanation wasn't too bad for complexity as such things go.

      There are a lot of concepts like internal energy, enthalpy, entropy, heat, temperature, etc which are often understood casually, but which have careful mathematical definitions. Once you understand the definitions you can work out the concrete relationships among them, and how things like engines work.

      As others have explained, the bottom line is that an engine is powered by the flow of heat, and limited by how quickly you can bring heat in and get rid of it.

      There has been talk of efficiency, but that comes down to a measure of what amount of the heat can even be used at all. For example, if you have a huge dam with a 1" drop in height, you can do as much work as hover dam, but you waste a LOT more water. In the same way a boiling water reactor (temp diff of 100C - 20C) isn't as efficient as a pressurized water reactor (maybe 150C-20C), and a liquid-metal reactor (maybe 500C-20C?) gets a lot more work done with the same amount of fuel consumed. This is also why an electrical care is theoretically a lot more efficient than a fossil-fuel car, even if the electric company burns fossil fuels. They can burn the fuel at a higher temperature, which means more energy is captured from the same amount of fuel burned.

You have enough gravity to keep stuff in place, and allow conventional building techniques (unlike in orbit), but you can make your trusses and beams slimmer, 'cause they don't have to carry as much weight. You can build out of polystyrene instead of steel, so to speak.

Say there was a huge, thriving civilization 50k years ago? There would be nothing left of it by now. Who knows what wonders could lie in our distant past?

    An Earth day has no always been 24 hours long (and will not remain so). Orbital interaction with the moon is gradually slowing down the rotation of the planet, and increasing the length of a day. Most estimates put the original rotation period of Earth at closer to 14 hours.

    So basically, only reason humans are "24 hour cycle" creatures is because this is the environment that we evolved in. As the day lengthens (assuming we're still here), we'll adapt to that as well.

    Thank you so very much for reminding me of that song.

    It took me four years off and on to purge it from my cerebral cortex with a Brillo pad. All for naught.

    I hope RuPaul covers this song someday, and that the new version haunts you to the end of your days, like a curiously tall diva wailing in the eternal night.

    "I read somewhere that Venus and Earth may have had similiar chemistries when both planets were created."

    Basic theory is that water could have existed on Venus because back then the sun was young and not so bright. As the sun got brighter on it's way to achieving it's main sequence state, the increased radiation boiled Venus because it was much closer to the Sun than the Earth.

    In a few billion years the same ought to happen to the Earth as it grows to red giant size.

    A short answer would have sufficed, but since you gave a long one I'll answer a the points. For the record, I'm summarizing you as objecting to my politics.

    1) Regarding the pitiful understanding of the economics based on my sig - Not true. I am completely aware that my comment is inaccurate economically. The purpose of it is rhetorical. It's meant to irritate conservatives. So, your assumption that I don't understand the economics isn't right on that point, but if you want to avoid presentations of liberal thought, which I will spare you here, it was probably a correct choice to foe me. I probably do say a lot of things which would irritate you far more.

    2) I was already pretty certain that I wasn't foed because of the Ubuntu thing, though I noticed quite a lot of heat around that in your history. I'm a Debian guy. Don't give two shits about Ubuntu.

    I do find it amusing that you bitch about people modding you down because they disagreed with you, but you foe me because you don't want to read something that you disagree with. I find it doubly amusing that I think music pirates should be shot at dawn for stealing music. Don't get me wrong. I'm not complaining about it. You SHOULD foe me, because I'm a rotten bastard. I've even written journal entries explaining that since I'm such a rotten bastard anyone who has me as a friend should be thoroughly ashamed of themselves.
