mars vs venus colonization

Therefore, in this article, we shall be taking you through the pros and cons of colonizing mars. “But it’s also complementary to current Mars plans.…There are things that you would need to do for a Mars mission, but we see a little easier path through Venus.” It is probably impossible to develop a Venus suit in the near-future. Colonizing venus vs colonizing the moon vs colonizing mars. Clever ending and overall marvelous writing. Since no lander has ventured on to Venus since the 1980s, the Venera program's images of the surface stand as the best close-up record of the planet today." Landing large amounts of mass on Mars requires heat shields and rocket propulsion. 100m/s and the atmosphere contains sulfuric acid. ( Log Out /  The pressure is very close to the death zone, the winds are cyclonic and up to 100m/s and the atmosphere contains sulfuric acid. Recon is easier on Mars, therefore, Mars. We’ve got some awesome news for you. ... Mars only has a third of the gravity that the Earth does, while the moon has a mere sixth. Many arguments have been made for and against space colonization. Venus requires importing about 40 quadrillion tons of hydrogen to lock up enough of the excess carbon and oxygen in its atmosphere in the form of water and biomass before its atmosphere can be thinned down enough to make the surface easily survivable. The only thing Mars has going for it is about double the gravity (1/3g vs. 1/6g), but it's much much much farther away from Earth than the Moon. A spacecraft that can launch from LEO and land on Mars can easily have the propulsion capabilities needed to launch back to Earth for another mission, if it can refuel on the surface. That's what I'd thought. Mars requires little more than a pressure vessel and the life support you'll need anywhere. The question is about Venus' upper atmosphere (about 32 miles high), not about landing on its surface. Why? Rather than land locked bases as on Mars you would have all these large air ships floating around. And of course, How? Towards the poles zonal winds diminish in speed to almost zero. The main concept with Mars colonization is focused on creating capsules, like the International Space Station, and securing them to Mars’ surface. Number of permanently airborne installations on Earth: 0. We just need to use an air mattress. There'll probably be active temperature control, but it would be feasible to keep things survivable passively. The lower pressure means it is harder to get oxygen, but with supplemental oxygen this is avoided. Curiosity has existed for much longer.

The tech required to build a payload that could use machines that mine asteroids and build more machines to do the work, eventually building giant Solar shades for Venus or Mirrors for Mars, ect., All without a space based human workforce and nothing more than an initial cost, is not unfeasible. But because that would for ever make him the most famous human being that ever lived. The day/night rhythm is very similar to ours here on Earth: a Mars day is 24 hours, 39 minutes and 35 seconds; The only other two celestial bodies in orbits near the Earth are our Moon and Venus. Launching from Mars is far easier than launching from Earth or Venus. The Surprisingly Strong Case for Colonizing Venus. But on the subject of terraforming. Are you sure? You see so many news stories about the possibility of humans colonizing Mars, and many readers may get really excited by the idea. View all posts by grizzlyexpress. Mars has a lot of basalt too, but it has had enough tectonic activity to give it a more Earthlike variety of igneous and metamorphic rocks, and a long enough history of liquid water to form all sorts of interesting concentrated minerals. Maybe one of you may just find out how. The base of the planet is simply too hot, so Astrophysicists  would have to figure out how to get to Venus, but not land directly on the actual planet ground which is difficult. Landing large amounts of mass on Venus requires heat shields and parachutes, and enormous air-deployed balloons if you want to avoid the surface. Not because its fun or practical or profitable. Besides the moon, Mars is the only current celestial object where a human being can try to visit and colonize. Venus is actually an easier and less costly colonization proposition than Mars is. If terraforming were so extremely simple as to only increase the CO2 ratio from 0.03% to 0.04% and all of the doomsday horrors that theologian Al Gore preached will have come true already today (did they? Venus vs. Mars Colonization. Venus on the other hand everything dissolves in a few hours from the heat and acid which makes it a terrifying planet to visit. Colonization of Venus Although the surface of Venus is an extremely hostile environment, at about 50 kilometers above the surface the atmosphere of Venus is the most earthlike environment (other than Earth itself) in the solar system. While the surface is death, the clouds of Venus are the most habitable place in the solar system, besides Earth. This was what made Mars a “ Warm, wet paradise,”(How the Universe Works) instead of being destroyed by the sun. If you create cloud cities in Venus' upper atmosphere (like planned with HAVOC) you of course can walk on them. And because Elon Musk is dead set on becoming its first settler. For one, the round trip from Earth to Venus would be 30 to 50 percent shorter than it would be to Mars. However, mysteriously, it lost its magnetic shield, and with that, the possibility for life. We are talking about resource allocations on a planetary scale. How to Diversify Trump County Despite this unfortunate event, that occurred millions of years ago. The ease of high(er) pressure environments vs low pressure environments in regards to habitat size, redundancy, and safety in general. Also the propellant needed to land on the surface of Mars vs the near zero amount of propellant needed to deploy vehicles in the atmoshpere of Venus. Mars may have enough trapped volatiles to allow walking around on the surface in an oxygen mask, just by warming the planet up. Small payloads can get some use from parachutes. To get home from Mars, you'll need 6 months, and … Colonizing Mars might seem like a great idea, but should we go to Venus instead?Watch more: Check out Seeker! Most of these stem from the lower cost of access to the Moon. But I have been looking at both and I too agree that Venus is more terraformable than Mars. There are a number of reasons that the Moon is the best place to start space colonization, but the basis of most of them are its proximity to the Earth. There are far fewer vital resources on the Moon, and a Moon day takes a month. Venus would require buoyant habitats drifting through skies filled with concentrated sulfuric acid mist. Â, However, Venus may be easier to adjust to, for it is a similar size as earth is, which means that the gravity will be similar  and safer as well. There are some things that will kill you on the moon/mars but not Venus (lose of power to heating/cooling, and leaks will be slightly less urgent) but you also do not have handy access to a surface to keep spare parts on, mine from, bury your reactor in or just to keep your two domes in the same position with respect to each other. Short-term costs vs. long-term gains. Mars lost its magnetic shield which was the only thing guarding it from the sun’s rays. As this episode of Space Time explains, there's a huge disparity between the kind of attention that Mars and Venus get, both from space agencies around the world, and in popular culture. We should colonize Venus first. More from. Mine CO2, Water (from sulfuric acid), and necessary "fertilizers" from the atmosphere, Mine acidic salts from the surface to make more water. For one thing, Venus is much closer to Earth than Mars is and launch windows occur much more often as well. This allows transportation between Earth and Venus to be much shorter, much more common, less resource-intensive, and overall easier. Forget Mars. The reason we are more likely to to Mars first is because the long term habitation of it is more feasible, we won't be mining Venus for raw materials so any habitation of it would be for purely scientific research purposes. After Yuri Gargarin, John Glenn, Neil Armstrong and Sally Ride exceeded these limits and touched the stars, there was hope in colonizing the planets closest to Earth, such as Mars and Venus. PBS's terrific series Space Time has tackled the subject of how we might go about colonizing Venus, but this new video puts it head-to-head with Mars on … Nowadays, there is a chance for us to colonize there, but is it the right choice? wouldn't designing larger habitats with more buoyancy allow for more control and stability? Change ). @user27822 Typical flat-earther? Turns out Venus had oceans between 4 billion and 1 billion years ago — way longer than liquid water existed on Mars, and more than enough time for it to develop life. https://space.stackexchange.com/questions/27797/venus-vs-mars-for-colonization/30376#30376. The surface appears to be entirely volcanic, basalt as far as the eye can see (about 3 km under surface conditions). There's clays, useful salts...one of our rovers got stuck in a patch of powder that appeared to be iron sulfate, and there's going to be similar deposits of copper minerals and other stuff you're going to need to actually build anything. And Mars has the raw materials needed to produce propellants. But the real question is, which one? Venus would be easier for multiple reasons. Which are those fertilizers in the atmosphere ? 3d printing will make available all the spare parts you need. For years, folk at NASA have always assumed that Mars would be the one to colonize first. Right now, we've got the US and Chinese governments interested in sending manned missions to Mars. https://space.stackexchange.com/questions/27797/venus-vs-mars-for-colonization/30373#30373, https://space.stackexchange.com/questions/27797/venus-vs-mars-for-colonization/33036#33036, https://space.stackexchange.com/questions/27797/venus-vs-mars-for-colonization/36897#36897. Not sure if this is allowed but Convince Me. Since the 1950’s, Astronomers have wanted to attempt allowing a human to go into space and discover what lies beyond our planet and the solar system. Why is Mars getting so much attention vs Venus, which to me seems like a much more attractive option, in regards to habitability. on Mars vs. Venus: Which Should We Colonize First? Both Venus and Mars have their problems, but what make the real difference is our lack of experience in missions that are not surface-based, since on Venus we should colonize the upper atmosphere layers. Discussion. Sometime soon, something’s gonna happen that will send you tumbling over into a whole new era of human evolution. (max 2 MiB). With the discovery of Venus' hostile surface environment, attention has largely shifted towards the colonization of the Moon and the colonization of Mars. The problem with Venus is that we cannot land on the surface. * This question is along the same vein as Venus vs Mars for colonization but without the person at the table. The logo and name of the Lunar Gateway references the St. Louis Gateway Arch, associating Mars with the American frontier. It is proposed here that in the near term, human exploration of Venus could take place from aerostat vehicles in the atmosphere, and that in the long … The predominant perspective of territorial colonization in space has been called surfacism, especially comparing advocacy for colonization of Mars opposed to Venus. Follow The Grizzly Express on WordPress.com, Eight of the Grossest “Delicacies” to Ever Make it on Survivor. Change ), You are commenting using your Twitter account. Click here to upload your image My interest in Venus colonization is in large part driven from a literary perspective. Even aliens would take notice. Terraforming is out of the question untill we can automate to process completely. NASA’s real-time portal for Mars exploration, featuring the latest news, images, and discoveries from the Red Planet. But few of these stories mention the many drawbacks and downsides of human colonization. instead of building like a compact submarine, you could build like a large cruise liner. You read that right. I think a Sci-Fi story taking place on Venus would be very interesting, because the type of society that would exist there would be very different from Mars. Venus would require buoyant habitats drifting through skies filled with concentrated sulfuric acid mist. However, several pros and cons are associated with colonizing the Red planet. But for a species that is currently having a heat crisis of its own homeworld, I think we are far off from being able to fix that. But geologically and chemically Venus has more favorable conditions than Mars. I don't know of any reason humans can't exist at ~500mbar other than the whole "needing to breathe" thing. I've read that the upper atmosphere of Venus has the most Earth-like conditions in the solar system, also terraforming seems pretty straightfoward. And who knows? This can work for a scientific mission where you arrive, deploy a limited lifetime balloon and abort to orbit when resources run out, you get blown into a cyclonic region or anything else goes wrong but a permanent habitat has to persist hopefully forever in that environment and becomes a lot more complicated, where the need to remain afloat at an altitude approximating 18000 feet on earth while surviving turbulence means that your weight will be critical (think living in an RV/caravan, not Bespin mining station). Terraforming is still very much sci-fi and far off from any fact. Venus has some significant advantages over Mars, especially if your goal is to create extra-terrestrial Earth-like habitats whose inhabitants can easily visit or return to Earth without suffering any problems with Earth’s strong gravitational field: Venus’ gravity is closer to Earth-normal than anyplace else in the solar system. Unlike Mars which has a litany of problems to overcome, Venus has just one, it is too hot. Hydrogen is much more buoyant there than on Mars and can be used to float a craft 90 miles above the surface where atmosphere pressure is equal to Earth and it's only 120-140 degrees F. It’s worth noting that Venus would be more attractive for human colonization because of its proximity and size similarity to Earth. Mars vs Venus Colonization The Pro proceeded on using my words against me to make it look like that people could ONLY live on Mars underground. A low-pressure breathable oxygen atmosphere could be built using oxygen sourced from rocks, with a byproduct being enormous quantities of metals and silicon. level 2. Terraforming is not necessary for colonization, but: The official student news site for Greenfield Junior High. The most crucial difference between Mars and Venus is that Venus is still protected by a Magnetic shield making it actually safer than Mars because the Sun cannot endanger the planet. The density of carbon dioxide (96.5 % of the venusian atmosphere) is 1.98 kg/m^3, the density of air is 1.293 kg/m^3, that is only 53 % more density. Mars is also subject to winds and seasons, whereas the temperatures on the moon can vacillate between 253 degrees Fahrenheit and -387 degrees Fahrenheit in a single day.The moon’s lack of an atmosphere is the result of its paltry mass and weak gravity. Colonizing anywhere is going to involve moving large amounts of material, and ideally you'll want to get multiple trips out of the spacecraft used for the job. If you want to visit home from the Moon, a ship can take you there in 3 days. Before discussing the advantages of the Moon, let’s analyze what a full-court press for Mars colonization look… Surface robotics would have to be built to tolerate conditions where common solders melt, aluminum alloys soften, and most plastics evaporate. When we think of colonizing space, our first thoughts are to the Moon and Mars. And that can have a big impact on policy surrounding space exploration. Was just curious about that one specific point. Those comments though were to show how early initial, pre-earth colonization of Mars would be. Terra-forming, isn't really considered as a valid mission plan yet (for either of the planets). We would end up having to colonize in the clouds of  Venus, like in Star Wars “Cloud City”. Because of the smart and intelligent minds out there all you have to do is use it. We’re gonna colonize Mars. With Mars we can reuse what we learned from the Moon. But the real question is, which one? I agree with some of the comments, terraforming should not be considered a serious target at this early stage of solar system colonization. Surface robotics would have to be built to tolerate conditions where common solders melt, aluminum alloys soften, and most plastics evaporate. For years, folk at NASA have always assumed that Mars would be the one to colonize first.  We discovered that a while back, Mars possessed a  magnetic field protecting it from the sun’s deadly radiation. https://space.stackexchange.com/questions/27797/venus-vs-mars-for-colonization/44932#44932. The colonization of Venus has several significant advantages over the colonization of Mars. Our current technology can handle Mars. ( Log Out /  "easy" is a big overstatement. ), then we could easily turn Mars into a second paradise. If we get hit by one of them while we’re there, it will be fatal.Â, If Mars is too risky, then why not just set up on Venus, right? Your ability to sustain a colony without any mineral resources from the surface will be limited, not to mention the complication of deploying giant balloons during descent for every incoming transport. Right now, you are standing on the edge of history. @GremlinWranger oh yeah totally agree that the issues are usually understated and you did a good job outlining that. The reason Mars gets more attention than Venus is because we could walk on Mars. It also does not have an atmosphere to form a barrier against radiation. There, the temperature and air pressure are about halved, perhaps managable. Yeah, you. Also, Venus is much more difficult to launch from than Earth, since not only do you need a similar sized multi-stage rocket, but you need to launch it from an floating platform. After Yuri Gargarin, John Glenn, Neil Armstrong and Sally Ride exceeded these limits and touched the stars, there was hope in colonizing the planets closest to Earth, such as Mars and Venus.
