General Discussion & Feedback > Just Chat! Imagine how you might rewrite all the athletic records on ever achieved on Earth with ease! Terraforming Wiki is a FANDOM Lifestyle Community. A life sustaining planet (s) undergoes some catastrophic event which sends it hurtling through space, where eventually it crashes into Earth and seeds it with life, or the components for life. We can fill this dome with the right amount of gases that are present in the earth’s atmosphere – the right mix of oxygen, carbon dioxide, water vapour, and nitrogen – and also the right kind of temperature comfortable for humans. liveable, not terraformed. Perhaps our earth is being used by off-planet entities for its resources, and the planet is being actively terraformed to maximize the efficiency of resource extraction. Earth is the third planet from the sun and home to the only known life. In all other ways, this planet is identical to earth, it has the same current flora and fauna, the same geomorphology, the same climate, etc. Mean: 15 degrees celsius. originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and … forms To transform on another planet into one having the characteristics of landscapes on Earth. The idea is essentially this: What would happen to history if the planet humans "grew up" on (in a civilization) sense was actually a terraformed world. [Sidereal] Rotation Period: 23hr 56min 4.1sec. Plants preceded animals onto land about 470 million years ago, and literally 'terraformed' the Earth — changing geochemical cycles and reshaping the world's atmosphere. It normally involves inserting plants and/or flora, introducing new minerals or substances, or other changes to fulfill the required goals for the planet in question. Plans are being made to terraform the entire Sahara desert; changing it from a dry, barren landscape to a lush green space. However, there is no way Mars could ever be terraformed in our life times. Alien life decided Earth was a candidate for terraforming, and did so, adding amino acids, water, organic carbon, photosynthesizing life, etc. It's just impossible. Also, for the sake of the experiment, the humans on the planet have no idea they 'seeded' the world. Terraforming is the process in which a planet is changed or "formed" to suit the needs of those terraforming the planet. I'll put some of what I think in the comments, feel free to add to it though. Terraform definition, to alter the environment of (a celestial body) in order to make capable of supporting terrestrial life forms. 3. A Mars with Earth like livability would definitely be intriguing. And we can imagine Venus as a terraformed world, purposely made to be more habitable and Earth-like again. A Hypothetical Map of a Terraformed Mars Terraforming means (especially in science fiction) transforming (a planet) so as to resemble the Earth, especially so that it can support human life. That took billions of years on Earth, and it would probably take at least hundreds of thousands of years on Mars. Galago - Galagos on Mars are descendants of ones that were brought from Earth to terraformed Mars around 25 million years ago by some ancient time-traveling space-travelers. A Speculative Fiction staple, the act of turning an otherwise human-unfriendly environment into an Earth-like, or "Terra-formed" planet. Earth and Mars formed about the same time. Galago - Galagos on Mars are descendants of ones that were brought from Earth to terraformed Mars around 25 million years ago by some ancient time-traveling space-travelers. It was shown to be very unstable, desolate, and the land was dominated by seismic and volcanic activity, with exposed lava being present right underneath most of the planet's surface. They think they are the originals. Take your favorite fandoms with you and never miss a beat. The map "An Invasion" gives a small peek into what the planet looked like in a pre-terraformed state. I have been having this thought experiment and was wondering if anyone else would care to add to it. It is a relatively large planet with at least two natural satellites (moons). Lights Off. Narratively, this is done to give the cast a place to go outside the ship (off Earth) that won't require them dressing in Space Clothes constantly. It has recently become apparent, by the collision of L-cross into the Luna’s South Pole, that Luna also has plenty of water in the form of ice. By using our Services, you agree to our use of cookies.Learn More. The only thing that is different, is that this world was dead about 10,000 years before humans settled it. A wide variety of galago species resembles Earth's galago, with one exceptional species resembling the fictional clatta from Dougal Dixon's After Man. Transforming the inhospitable Martian environment into a place astronauts could explore without life support is not possible without technology well beyond today’s capabilities because Mars does not retain enough accessible carbon dioxide that could be put back into the atmosphere to warm the planet. Can the Moon be terraformed for humans? On Earth, we're exposed to about 0.066 rems of radiation per day. At higher altitudes, this decreases as the atmosphere becomes thinner. A planetary takeover by ocean-dwelling algae 650 million years ago was the kick that transformed life on Earth. Terraforming is, "the hypothetical process of deliberately modifying its (a planet's) atmosphere, temperature, surface topography or ecology to be similar to the environment of Earth to make it habitable by Earth-like life." It is the model of what we would want terraformed bodies to look and feel like, in simplest terms. The Earth may well have been terraformed. The terraformed planet appears to look much like Earthfrom orbit, with large green continents and massive, shining blue seas. Terraforming would mean creating the right environment outside the domes so plants could grow … Maximum: 56.7 degrees celsius. << < (3/3) Make it Lady: I think that god is a spaceman. We live on a young planet, in the ultimate scale of things. A wide variety of galago species resembles Earth's galago, with one exceptional species resembling the fictional clatta from Dougal Dixon's After Man. H&F: You’ve written that fully terraforming could theoretically be possible within 17 years if operating at a rate of 100% energy efficiency and 100% efficiency of transforming carbon into oxygen. Sagan imagined seeding the atmosphere of Venus with algae, which would convert water, nitrogen and carbon dioxide into organic compounds. Well, minus the “terra” part perhaps. Mean: 15 degrees celsius. [Dry] Atmosphere: 78.08% Nitrogen, 20.95% Oxygen, 0.93% Argon, and 0.039% Carbon Dioxide. A viral map highlights how terraforming Venus could result in an impressively Earth-like planet. If successful, the transformation could remove 7.6 billion tons of atmospheric carbon yearly. 2 Was Earth terraformed by aliens? Eventually, terraformed to support life, like Earth." In contrast , Ganymede receives 8 rems of radiation per day, Europa receives 540 rems per day, and Io receives a whopping 3,600 rems. Terraforming would mean creating the right environment outside the domes so plants could grow just like on Earth and there would be an oxygen supply. 2. The terraforming of Mars is a hypothetical procedure that would consist of a planetary engineering project or concurrent projects, with the goal of transforming the planet from one hostile to terrestrial life to one that can sustainably host humans and other lifeforms free of protection or mediation. Surface Temp: Minimum:-89.2 degrees celsius. [Dry] Atmosphere: 78.08% Nitrogen, 20.95% Oxygen, 0.93% Argon, and 0.039% Carbon Dioxide. At 3000 m the oxygen level is 0.14 atm and there are a few major cities at this altitude, mostly in the Andes and in … Surface Temp: Minimum :-89.2 degrees celsius. Earth is the third planet from the sun and home to the only known life. And from what we can see of the colorful spider-web patterns of land, this world has most definitely been terraformed. But once Mars cooled it became clement, thus between about 4.3 billion years to 3.5 billion years ago, it … In 500 or 1000 years from now, yes I'm a believer. It is the model of what we would want terraformed bodies to look and feel like, in simplest terms. He then came back some time later and saw early man and that his evolution had come to a halt so he did a bit of artificial insemination and kicked it off again...read missing link. If Triton’s sculptor was using Earth as a model, this world represents an epic fail. Earth is Terraformed, what if? The early terraforming tended to use genetically engineered biological processes that would change the atmosphere of a suitable world over many decades to a breathable atmosphere using energy captured from the star via biological processes. An MG facility was establish… This means that there was no previous life before humans 'seeded' the world and as such no fossils, no fossil fuels, no limestone, no marble, no shale, etc. Moon can be terraformed by bringing its environment inside a largely transparent and leak-proof dome. Cookies help us deliver our Services. Yet here on Earth life is around 4 billion years old. What changes? The idea is essentially this: What would happen to history if the planet humans "grew up" on (in a civilization) sense was actually a terraformed world. It can take up to several centuries to fully terraform an Earth-sized planet, or even slightly larger. The astronomer Carl Sagan proposed the planetary engineering of Venus in an article published in the journal Science in 1961. As this process removed carbon dioxide from the atmosphere, the greenhouse effectwould be reduced until surface temperatures dropped to "comfortable" levels. In the latter case, and owing to Mars similarly tilted axis (25.19° compared to Earth’s 23°), Mars experiences seasonal changes that are very similar to Earth’s. The term 'terraforming' was first coined by Jack Wiliamson in the scifi story Collission Orbit which was published in Astounding Science Fiction in 1942.
