Over 20 successful space missions have visited Venus since 1962. I don’t see why we wouldn’t try it if we had to. wtf is going on at mimas? http://arstechnica.com/journals/science.ars/2008/07/22/powered-enzyme-reduces-carbon-dioxide. Back in about 1962 when Carl Sagan first talked about the concept of terraforming Venus, it wasn’t known what a challenge Venus would be. However, viewed in a different way, the problem with Venus is merely that the ground level is too far below the one atmosphere level. That’s like yelling at McDonalds for Burger King’s new fries (I just saw Wall-E, all I can think of are corporate restaurants. This is due to the fact that the city of Venice consists of 118 small islands connected by numerous canals and bridges. Asked if he has ever thought about terraforming Venus, Landis said, “Oh, yes, of course! The Venusian habitats could provide atmospheric gases and polymer building materials to the inner system. Airhaven is a floating city in the Mortal Engines Quartet, that, through attaching gas bags, lifted itself into the air to avoid cities trying to eat it according to Municipal Darwinism. (This part of the system would … Nasty triple threat atmosphere on Venus. Same goes for terraforming Mars, by the way. With current propulsion systems, launch windows to Venus occur every 584 days,[3] compared to the 780 days for Mars. [12] Compared to the Venusian solar day of 118 Earth days, colonies freely floating in this region could therefore have a much shorter day-night cycle. Photo: Bloomberg Nasa plans airships, floating city above Venus clouds 1 min read. Use in situ resources to build a geodesic sphere with a diameter measured in kilometers. As long as enough of them stay afloat, they could slowly eat the sulfur and Carbon in CO2 and take it with them when they fall down, clearing up the upper skies and providing oxygen too. Maybe workable for people, too, but still not safe enough to live there for anything but research. NASA plans to send solar-powered airships to explore Venus' atmosphere Still, with fledgling companies like JP Aerospace, who are working on just such a project for the Earth’s upper atmosphere, the basic R+D might very well be in place by the time it comes to seriously explore such a concept for other planets. For executions we could just toss ’em over the railing and send ’em straight to Hell. It’d be nifty if we could find some way of effectively desulphurising SO_2_/SO_3_/H_2_SO_4_ to get a local source of oxygen. “What I like to say, the problem with Venus is if you define sea level as the place in the atmosphere where it’s the same as Earth, the place of “sea level” on Venus is just too far above the ground.”, While Landis’ plans for a solar powered airplane are a true possibility for an upcoming mission to Venus, his ideas about colonizing that planet are a little more speculative. Most other space exploration and colonization plans face concerns about the damaging effect of long-term exposure to fractional g or zero gravity on the human musculoskeletal system. This way we can simply shut them all down when they’re done. Soo.. if floating oxygen and nitrogen bubbles is a practical idea, why send a plane? On the nanotech side, microbial artificial life has already been created in labs. I wouldn’t be so pessimistic if I were you. Its gravitational acceleration is almost the same as Earth’s. Join our 836 patrons! Certainly, it is a scary prospect for everyone Today, Venus is inhospitable, and it is unlikely to be dream place for the space tourists. Our air is lighter than air, or at least lighter than the Venus atmosphere.”. Build a bunch of balloons, each with it’s own freezer that would siphon in carbon dioxide and freeze it into huge blocks of dry ice. Read Later ; Print. Possible or not, I can’t think of a single compelling reason to do it. The last European probe was ESA's Venus Express, which was in polar orbit around the planet from 2006 to 2014. Maybe that should be “Landis” Calrissian. The Construction of Venice, the Floating City. they can multiply their numbers exponentially.”. I would like to see some sort of technology developed that would allow us to send floating unmanned research stations into the atmospheres of the outer planets. The outer shell would be photovoltaic, with a regenerative glass or similarly transparent sulfur shield. No more worries about solar flares, meteorites, sudden decompression and roasting/freezing to death. One propelled by solar-powered ion engines, at that. Proposals also involve either freezing most of Venus's atmospheric CO2, or converting it to carbonates,[18] urea[citation needed] or other forms. No magnetic field, and no ozone layer, may not be a big problem: Stay on the night side, and you don’t get zapped with UV *or* charged particles *or* X-rays from the Sun. Colonization of space was claimed by Stephen Hawking to be the best way to ensure the survival of humans as a species. The energy required just to get the space station into L.E.O has been mind-boggling enough, and that’s just a piddling little thing! Many reasons to do it. NASA is currently doing just that; floating a concept that could one day see a 30-day manned mission to Earth’s closest planetary neighbor. I don’t expect people will be building cities on Venus, at least probably not in this century.”. One of the things that have not been addressed in all the planetary colonization schemes (as far as I know) is what will the affect of living and procreating in a gravity environment that has significantly less acceleration than Earth’s have on us? First, Venus is slightly closer to the Earth than Mars is, so it’s faster and easier to get there. And people wonder why I want to see the human race wiped out.. I’d love to terraform Venus.. and then populate it with a race of heavily-armed robots with orders to shoot humans on sight. Another common thread in most proposals involves some introduction of large quantities of hydrogen or water. and also, the small size of bacteria is one of their chief advantages. This is one of the reasons that I would tend to agree with Gerard O’Neill that our off-Earth colonies should be rotating in free space where we can control the acceleration environment as apposed to planetary surfaces. But the more we look at the problems, the more we say, goodness, terraforming is a very difficult proposition.”. Washington: NASA plans to send solar-powered airships to explore … There’s not enough left to make any major bodies of water on the surface if the planet were cooled down, but there’s plenty left to harvest for industry and habitats. Seal it and the air inside adds lift too. I think this city be a great idea. For a more logistical and informative piece on this, visit http://en.wikipedia.org/wiki/Colonization_of_Venus#Aerostat_habitats_and_floating_cities. So it now has an excess of oxygen, which led to the CO2 smothering blanket in the air. Venice, Italy, is known by several names, one of which is the ‘Floating City’. Plus, the sun has like 6.5 billion years before it takes out the solar system. With all the talk of inflatable space stations now a days it doesnt seem like that far of a strech to turn inflatable space stations to venus blimp cities. In most of the space exploration news on man’s attempts to colonize the solar system, you mostly hear of proposed manned mission to the red planet Mars. Staff writer. That is where all the women are! While I am by no means a famous writer, I wrote about this exact same thing in various internet forums over a decade ago. Besides, think it through. Industrialising Venus would motivate investment in floating facilities there. “If you could just take the room you’re sitting in and replace the walls with something thinner, the room would float on Venus,” said Landis. This might be an interesting way to put sats up there in general. Venus has certain similarities to Earth which, if not for the hostile conditions, might make colonization easier in many respects in comparison with other possible destinations. Source: PTI. Instead, they were built upon wooden platforms that were supported by … Of course the bots and flying sensors are well worth it and will increase in the future in their atmosphere. So go ahead and plan it for Venus and then we can have it here on Earth ready to go in case a catastrophe requires it. Nanotech has come a long way in a short time and in the least the most primitive type of derivative innovations which would be needed to accomplish terraforming will likely be developed in the short term (probably 2015 to 2020). I wonder if, someday in the future, we use technology to siphon off excess gasses from Venus, transport them to Mars and release them into Mars’ atmosphere. “This idea is just flaming bonkers. If it is ever colonized it will be because there is a demand for some mineral, ore, metal, or gas which might be found abundant on or in the surface. Blow-molding “large” sections could then be snap-fit together and pressurized with air to be the floating balloon city. • A Floating City on Venus – article from The Space Monitor I suspect thngs would look more like the mess shown in ‘The Fifth Element,’ rather than the neat, orderly flyways of ‘Back to the Future II’ or ‘The Jetsons.’, I don’t trust a lot of people to drive in TWO dimensions…. Why go? the easiest way to terraform Mars is to use robot space craft to ‘nudge’ large comets so that they collde with Mars– possibly using nuclear blasts to alter the cometary orbits. There needs to be a lot more research into the effects of low acceleration environments on the human body and its development, before we can confidently consider colonizing any world that is significantly smaller than Earth. “Why build the cities floating in the atmosphere? http://astrobiology.nasa.gov/ask-an-astrobiologist/question/?id=562. ha! Just think about the wind in the upper atmosphere, considering the slow rate of revolution of the planet – only one side is heated, due to that, unlike earth. (3) It seems that a unmanned operation, at most, would be far more practical on just about every level, barring very unusual discoveries on Venus into the foreseeable future. Fuller proposed an geodesic floating city on Earth. Because I feel like it. However, this has its benefits…sunrise to sunrise is about 117 days, and it would be quite feasible for a habitat to circle the globe (perhaps powered by solar-thermal jet engines) in that time, staying in continuous sunlight. Venus is effectively the only other source of nitrogen in the inner system aside from Earth itself, and although Venus is very dry, the atmosphere does contain water, and sulfuric acid which can be converted into water or itself used in industrial processes. and it may never. Or if you’re hellbent on being in Venus’s atmosphere, build a huge tower a hundred miles tall and lower it to the surface, then put the city on it. Link 3 or more of these spheres together in triangle formations for stability so that wind or minor mass movements within the sphere won’t make them roll. The more you look at Venus, the more you say, ‘oh my goodness, terraforming would be a really hard project.'”. READ Mysterious Hammer discovered under the earth. All these probes we’re sending out aren’t preparing the planets for us, they’re simply gathering information about our solar system. this would create a water and oxygen loaded atmosphere almost instantly. NASA plans to send solar-powered airships to explore Venus' atmosphere and to eventually establish a permanent human colony in a floating cloud city above the Earth's nearest planetary neighbour. Share: Updated: Dec 21, 2014, 17:17 PM IST. My best guess is that they don’t actually mean *orbit* in the sense of being high enough and fast enough to circle the globe without power, and will eventually reveal that they’re marketing powered upper atmosphere airships as substitutes for orbital satellites. At 5 km (3.1 mi) higher, it is a temperate 27 Â°C (300 K; 81 Â°F) (see Atmosphere of Venus § Troposphere). these are bacteria found in hot springs and ocean vents. If they do this crazy project before they get around to me getting my own flying car I am really going to upset. Robotic machines would be covered in a layer of heat and pressure shielding ceramics, with internal helium-based heat pumps inside of the machines to cool both an internal nuclear power plant and to keep the internal electronics and motor actuators of the machine cooled to within operating temperature. This week, Landis goes a step farther (actually, several steps farther) with his ideas about colonizing Venus. They can be bred and engineered to do it faster in a higher CO2 environment, and there have been recent advances in doing it artificially, reducing CO2 to formate ions at high efficiency using electrical power: Sulfuric acid. Welcome to the floating city Let’s start with the pragmatic reasons to pick Venus as our next stop for human habitation. Establishing a floating city colony also gives humans much more 'practice' with inhabiting alien worlds. And couldn’t we just purchase enough carbon credits to thin out that atmosphere? I don’t think JP Aerospace is the company to look at…the upper atmosphere of Earth is a very different environment. That’s right, because the whole world revolves around you and your empty-headed consumer-driven “needs”, right? We’ve gone from caves to space stations. Allowing a colony to move freely would also reduce structural stress from the wind than they would experience if tethered to the ground. This also has the nice benefit of thinning out the Venus atmosphere, and perhaps making it a bit safer to terraform. [17][5] The proposals seek to remove or convert the dense carbon dioxide atmosphere, reduce Venus's 450 Â°C (723 K; 842 Â°F) surface temperature, and establish a day/night light cycle closer to that of Earth. and the upper clouds of venus are loaded with acidic water vapor….perfect for extremophile bacteria? If we’re talking about genetically tweaked bacteria, why would they have to be small? These blocks would be shot at high speed deep into the Venusian crust. Of course, like Mr. Landis said, though, this is just food for thought.
