On the pro-terraforming side of the argument, there are those like Robert Zubrin, Martyn J. Fogg, Richard L. S. Taylor and the late Carl Sagan who believe that it is humanity's moral obligation to make other worlds suitable for life, as a continuation of the history of life transforming the environments around it on Earth. Terraforming or terraformation of a planet, moon, or other body is the hypothetical process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to the environment of Earth to make it habitable by Earth-like life. Much study has been done concerning the possibility of heating the planet and altering its atmosphere, and NASA has even hosted debates on the subject. On Earth, this process is counteracted when plate tectonics works to cause volcanic eruptions that vent carbon dioxide back to the atmosphere. University professors, intellectuals and adventurers support the colonization idea because a one-way trip to Mars would be probably half as expensive as a full round-trip mission. There will be no moon at night ever though many stars with very pronounced twinkling…. Terraforming of Venus is the (theoretical) process of engineering the global environment of the planet Venus in such a way as to make it suitable for human habitation. Please check your entries and try again. The ultimate achievement in terraforming would be to create an open planetary. [2] Sagan imagined seeding the atmosphere of Venus with algae, which would convert water, nitrogen and carbon dioxide into organic compounds. Faure, Gunter & Mensing, Teresa M. (2007). [41][42], Gary King, microbiologist at Louisiana State University studying the most extreme organisms on Earth, notes that "synthetic biology has given us a remarkable toolkit that can be used to manufacture new kinds of organisms specially suited for the systems we want to plan for" and outlines the prospects for terraforming, saying "we'll want to investigate our chosen microbes, find the genes that code for the survival and terraforming properties that we want (like radiation and drought resistance), and then use that knowledge to genetically engineer specifically Martian-designed microbes". [61][62] It is reasonable to assume that these factors would also be present in planetary terraforming efforts. None have been found yet that can live in the temperatures and pressures similar to those on the surface of Venus but they probably do exist on Earth (or you could say ‘in’ Earth, well below the surface) and, at least theoretically, have not been discovered yet. In 1984, James Lovelock and Michael Allaby published The Greening of Mars. The biggest problem that the project needs to overcome, both for the self replicating nanobots and later the colonists, would be water shortage. The long timescales and practicality of terraforming are the subject of debate. Addition of water, since there is barely enough water vapor to cover the planet in a few centimeters thick layer of liquid water even if the planet is cooled. The low gravity of Mars suggests that these impacts could have ejected much of the Martian atmosphere into deep space. [26] A thicker atmosphere of greenhouse gases such as carbon dioxide would trap incoming solar radiation. It’s our nearest neighbor and our sister planet in size. Take your favorite fandoms with you and never miss a beat. [20] Convection within the core of Mars, which is made mostly of iron,[21] originally generated a magnetic field. Is Venus is a more tantalizing terraforming candidate than Mars? In 2015 the agency and some of its research partners have created a software called DTA GView − a 'Google Maps of genomes', in which genomes of several organisms can be pulled up on the program to immediately show a list of known genes and where they are located in the genome.

However the dynamo ceased to function long ago,[22] and the magnetic field of Mars has largely disappeared, probably due to "... loss of core heat, solidification of most of the core, and/or changes in the mantle convection regime. The existing environment of Venus would require four major changes to the planet: These goals are closely interrelated, since Venus's extreme temperature is due to the greenhouse effect caused by its dense carbon-dioxide atmosphere. The resulting carbon, Sagan supposed, would be incinerated by the high surface temperatures of Venus, and thus be sequestered in the form of "graphite or some involatile form of carbon" on the planet's surface. The hardiest hyperthermophiles yet discovered live on the superheated walls of deep-sea hydrothermal vents, requiring temperatures of at least 90°C for survival. [25], Terraforming Mars would entail two major interlaced changes: building the atmosphere and heating it. [49][50][51][52][53], The lack of a magnetosphere on Mars means the red planet is constantly blasted with solar radiation. Mars is usually considered to be the most likely candidate for terraforming. "[23] Results from the NASA MAVEN mission show that the atmosphere is removed primarily due to Coronal Mass Ejection events, where outbursts of high-velocity protons from the sun impact the atmosphere. Create the future. So you can have the best possible How but if you mess up your Why or What you will do more damage than good. There is no water on Venus to speak off. Copyright © 2009-2020 Singularity Weblog. Thus we should have an Oxygen/Nitrogen Atmosphere in a couple of decades that is probably about 60 Earth atmospheres in pressure, but without any serious greenhouse problems. You must accept the Terms and Conditions. In all likelihood, there will be other problems that I have not thought of or mentioned here so feel free to contribute to this idea. There is a debate about whether or not Venus can be terraformed into a planet capable of hosting terrestrial life. In Venus Next, the World Government chooses to also fund the terraforming of Venus. Venus, on the other hand, with its carbon dioxide atmosphere, even though it is both huge and hot because of its greenhouse gas effect, does give us something to work with. This would accelerate the production of oxygen, which theoretically would make the planet eventually able to support animal life. It has also been suggested that instead of or in addition to terraforming a hostile environment humans might adapt to these places by the use of genetic engineering, biotechnology and cybernetic enhancements. It will also be very hot and perhaps highly radio-active because Venus has no significant magnetic field with which to deflect the rays from the occasional solar eruptions as the Earth does. that due to the effects of climate change, an interventionist program might be designed to return Earth to its usual and more benign climate parameters. [8] Lovelock's book was one of the first to describe a novel method of warming Mars, where chlorofluorocarbons (CFCs) are added to the atmosphere. Such technology is not yet developed, let alone financially feasible at the moment. Schubert, Gerald; Turcotte, Donald L.; Olson, Peter. Hear their dreams and their fears. One problem is that the clouds of Venus are composed of a highly concentrated sulfuric acid solution. He also notes that it would be best to develop "not a single kind microbe but a suite of several that work together". Any carbon that was fixed in organic form would be liberated as carbon dioxide again through combustion, "short-circuiting" the terraforming process.[3]. First, alternatives to terraforming. One way to achieve this would be to smashing water-rich objects into Venus, possibly chunks of ice from Ganymede or Europa. Transforming Mars: Venus next, the second expansion to the smash-hit terraforming Mars, continues the journey of humanity as we terraform Earth's closest neighbor, Venus Adding a side game board for the Planet Venus, additional tiles and tokens, and most importantly new Venus cards to add to the deck, you will be saying Venus next! Planetologist Christopher McKay wrote "Terraforming Mars", a paper for the Journal of the British Interplanetary Society. Eliminating most of the planet's dense 9 MPa (~90 atm) carbon dioxide atmosphere, via removal or conversion to some other form. [43], DARPA is researching using photosynthesizing plants, bacteria, and algae grown directly on the Mars surface that could warm up and thicken its atmosphere. Research and theory in this regard is a component of planetary science and the emerging discipline of astrobiology. However, if as Ray Kurzweil often points out, humans will be able to transcend biology and merge with machines then it might be eventually possible for a human to walk around without any protective space suit (or even naked) on the surface of the Moon (or Venus, or Mars) if he or she is designed with a “heavy duty body.”. Haynes, RH (1990), "Ecce Ecopoiesis: Playing God on Mars", in MacNiven, D. (1990-07-13). Habitable Planet (HP): A world with an environment sufficiently similar to Earth as to allow comfortable and free human habitation. For other uses, see, "Terraformers" redirects here. On Mars, the lack of such tectonic activity worked to prevent the recycling of gases locked up in sediments. According to Alicia Jackson, deputy director of DARPA's Biological Technologies Office by this they have developed a "technological toolkit to transform not just hostile places here on Earth, but to go into space not just to visit, but to stay".[44][45][46][47]. This also makes any kind of travel to Mars (or anywhere else) near impossible. Then we come to the next and perhaps the biggest problem that we would need a solution for. John Hickman has pointed out that almost none of the current schemes for terraforming incorporate economic strategies, and most of their models and expectations seem highly optimistic.[60]. [35] Landis estimates that a 1 PSI atmosphere of pure oxygen on the moon would require on the order of two hundred trillion tons of oxygen, and suggests it could be produced by reducing the oxygen from an amount of lunar rock equivalent to a cube about fifty kilometers on an edge. 177–182, in, Journal of the British Interplanetary Society, Earth would eventually be destroyed if nature takes its course, "Science Fiction Citations: terraforming", "Inevitable future: space colonization beyond Earth with microbes first", "Goal 1: Understand the nature and distribution of habitable environments in the Universe", "APS X-rays reveal secrets of Mars' core", "Keeping Mars warm with new super greenhouse gases", "Why The Moon Should Never Be Terraformed", "Synthetic circuit designs for earth terraformation", "Population dynamics of synthetic terraformation motifs", "Towards synthetic biological approaches to resource utilization on space missions", "Video: Humans Could Engineer Themselves for Long-Term Space Travel", "You Can Now Play God From The Comfort Of Your Garage", "Here's How We'll Terraform Mars With Microbes", "Will tweaked microbes make Mars Earth-like?
