Combined with a thin atmosphere, this permits a significant amount of ionizing radiation to reach the Martian surface. Mars’s surface conditions and past presence of liquid water make it arguably the most hospitable planet in the Solar System besides Earth. Given its size and resources, this might eventually be a place to grow food and produce equipment to mine the asteroid belt. In part, this is because of the Outer Space Treaty, which has an extremely important and extremely relevant clause stating that nations cannot claim ownership of the land on celestial bodies. The path to a human colony could be prepared by robotic systems such as the Mars Exploration Rovers Spirit, Opportunity and Curiosity. Elle a envoyé une sonde en orbite autour de la planète en septembre 2014 et a marqué la première incursion réussie de l'Inde dans l'espace interplanétaire. Mars has an axial tilt of 25.19°, similar to Earth’s 23.44°. The vast majority of CO2 has been lost into space. Being made mainly of water, a human being would die in a matter of days without it. Summed up, sending people to Mars will be an expensive, complicated, and time-consuming matter, but a true colonization of the Red Planet will prove to be that much more so. For example, while Mars has water, there is so little of the precious substance on its surface that the colonization of Mars will need either regular shipments of water, some way to come up with more water, or both at the same time. Some analysts have calculated that one needs to drill into the Martian crust for around 16.5 kilometers at Hellas Planitia to achieve an air pressure equivalent to that on the summit of Mount Everest. Carbon monoxide/oxygen (CO/O2) engines have been suggested for early surface transportation use as both carbon monoxide and oxygen can be straightforwardly produced by zirconium dioxide electrolysis from the Martian atmosphere without requiring use of any of the Martian water resources to obtain hydrogen.[74]. The colonization of Mars is something that is actively being worked on today and research has shown that colonization is possible, but there are multiple viewpoints on the subject. Even a 5–8% decrease in total body water causes fatigue and dizziness and a 10% decrease physical and mental impairment (See Dehydration). Another main inter-Martian trade good during early colonization could be manure. Organizations have proposed plans for a human mission to Mars, the first step towards any colonization effort, but no person has set foot on the planet. A tiny amount of CO2 is locked into the ice caps, deep carbonates, and minerals. November 30, 2011. in Alien life, Space, Space flight, Studies. The atmospheric pressure on Mars is far below the Armstrong limit at which people can survive without pressure suits. [103], One possible ethical challenge that space travelers might face is that of pregnancy during the trip. According to NASA’s policies, it is forbidden for members of the crew to engage in sex in space. It is still not fully known how the environment in a spacecraft would affect the development of a child aboard. The next thing you'll know, there's a colony there!! [72], Colonization of Mars would require a wide variety of equipment—both equipment to directly provide services to humans and production equipment used to produce food, propellant, water, energy and breathable oxygen—in order to support human colonization efforts. [38] However, the surface is not hospitable to humans or most known life forms due to the radiation, greatly reduced air pressure, and an atmosphere with only 0.1% oxygen.’, In 2012, it was reported that some lichen and cyanobacteria survived and showed remarkable adaptation capacity for photosynthesis after 34 days in simulated Martian conditions in the Mars Simulation Laboratory (MSL) maintained by the German Aerospace Center (DLR). [20] to equally categorical Should Humans Colonize Other Planets? But this very thin layer can shield the possible colonies from harmful radiations and we can live on its surface. A space program called Mars One has been studying Mars for the past four years. It's more possible with Mars than the moon, only problem is getting there and being able to set up a habitat for humans. Robotic spacecraft to Mars are required to be sterilized, to have at most 300,000 spores on the exterior of the craft—and more thoroughly sterilized if they contact “special regions” containing water,[99][100] otherwise there is a risk of contaminating not only the life-detection experiments but possibly the planet itself. Before discussing the advantages of the Moon, let’s analyze what a full-court press for Mars colonization look… For Martian colonization to be successful and sustainable, Martian human settlements have to become viable economic units. These systems could help locate resources, such as ground water or ice, that would help a colony grow and thrive. Since the planet Mars offers a challenging environment and dangerous obstacles for humans to overcome, the laws and culture on the planet will most likely be very different from those on Earth. [30], The Martian soil is toxic due to relatively high concentrations of chlorine and associated compounds which are hazardous to all known forms of life. The hypothetical colonization of Mars has received interest from public space agencies and private corporations, and has received extensive treatment in science fiction writing, film, and art.. Satellite imagery shows that there is frozen ground water on the planet. Since terraforming cannot be expected as a near-term solution, habitable structures on Mars would need to be constructed with pressure vessels similar to spacecraft, capable of containing a pressure between 30 and 100 kPa.

La colonisation de Mars par l'être humain, c'est-à-dire l'installation d'une communauté humaine autonome sur cette planète est un thème classique de science-fiction et constitue un projet qui connait dans les années 2010 un engouement populaire important. Psychosocial sessions for the return home are also suggested in order to reorient people to society. You are not surviving entirely on your own if you have to rely on supplies from Earth. Shortening the travel time below about six months requires higher delta-v and an exponentially[clarification needed][an exponential function of what?] Four lucky individuals (depending on how you look at it!) Mars is the focus of much scientific study about possible human colonization. Just Visiting. ! Space colonization on Mars can roughly be said to be possible when the necessary methods of space colonization become cheap enough (such as space access by cheaper launch systems) to meet the cumulative funds that have been gathered for the purpose. For example, the 2004 President’s Commission on Implementation of United States Space Exploration Policy suggested that an inducement prize contest should be established, perhaps by government, for the achievement of space colonization. Aaah, someone finally directly asks the more fundamental question about human colonization of Mars: not how or who or when, but should. 0. It’s a clearer question than why because human motives are all over the map. [94], Alternative funding approaches might include the creation of inducement prizes. NASA has found that direct communication can be blocked for about two weeks every synodic period, around the time of superior conjunction when the Sun is directly between Mars and Earth,[76] although the actual duration of the communications blackout varies from mission to mission depending on various factors—such as the amount of link margin designed into the communications system, and the minimum data rate that is acceptable from a mission standpoint. According to the recent researches by the scientists, they fear that the radiations might be a potential threat for the scientists who will land on Mars. Mars has no rain and virtually no clouds, so although cold, it is permanently sunny (apart from during dust storms – see Climate of Mars). It has been speculated that settlers could benefit from the shelter that these or similar structures could provide from radiation and micrometeoroids. Local resources can also be used in infrastructure construction. Global dust storms are common throughout the year and cover the entire planet for weeks, blocking sunlight from reaching the surface. For starters, Mars and Earth have very similar lengths of days . This is rather ambitious, considering we are not even capable of putting people on our moon, not because of conspiracy theories that NASA faked the moon landing but because those technologies have been too long out of use. These include: The Martian day (or sol) is very close in duration to Earth's.A solar day on Mars is 24 hours, 39 minutes and 35.244 seconds. [20] Surface water on Mars may occur transiently, but only under certain conditions.[21][22]. See Atmosphere of Mars. And lots of money. [21] Equipment for moving over the surface – Mars suit, crewed rovers and possibly even Mars aircraft. Colonizing Mars is one of the most promising backup plans for humanity; Mars is relatively close to our Earth; Colonizing Mars may become possible in just a few decades; Many celebrities support those plans; Many scientists advocate for this kind of backup plan; Extraction of additional natural resources; May help with the search for other life forms [120], In June 2013, Buzz Aldrin, American engineer and former astronaut, and the second person to walk on the Moon, wrote an opinion, published in The New York Times, supporting a human mission to Mars and viewing the Moon “not as a destination but more a point of departure, one that places humankind on a trajectory to homestead Mars and become a two-planet species.”[121] In August 2015, Aldrin, in association with the Florida Institute of Technology, presented a “master plan”, for NASA consideration, for astronauts, with a “tour of duty of ten years”, to colonize Mars before the year 2040. This is minor in comparison to the 1100-day journey[51] planned by NASA as soon as the year 2028. Much remains to be learned about space radiation. increasing amount of fuel, and is difficult with chemical rockets. Although there are some extremophile organisms that survive in hostile conditions on Earth, including simulations that approximate Mars, plants and animals generally cannot survive the ambient conditions present on the surface of Mars. Equipment for energy production and energy storage, some solar and perhaps nuclear as well, Propellant production equipment, generally thought to be hydrogen and methane through the Sabatier reaction[73] for fuel—with oxygen oxidizer—for chemical rocket engines, Fuels or other energy source for use with surface transportation. Sunlight on the surface of Mars would be much like a moderately cloudy day on Earth.[90]. The existing record for the longest consecutive space flight is 438 days by cosmonaut Valeri Polyakov,[49] and the most accrued time in space is 878 days by Gennady Padalka. There are also severe radiation risks on Mars that can influence cognitive processes, deteriorate cardiovascular health, inhibit reproduction, and cause cancer. Its surface conditions and the availability of water make it arguably the most hospitable of the planets in this solar system, other than Earth. Legally, the colonization of Mars is going to be a horrible mess. Due to the communication delays, new protocols need to be developed in order to assess crew members’ psychological health. Resource extraction equipment—initially for water and oxygen, later for a wider cross section of minerals, building materials, etc. A solution common to both groups is to release carbon dioxide gas trapped in the Martian surface to thicken the atmosphere and act as a blanket to warm the planet. A solar day on Mars is 24 hours, 39 minutes and 35.244 seconds.[12]. In order to function at all the colony would need the basic utilities to support human civilization. In the former case, a trip time of forty days could be attainable,[66] and in the latter, a trip time down to about two weeks. 0. Some experts have argued for setting up open-air settlements by using special construction methodologies- like excavating deep into the Martian crust to depths where air pressures may be sufficient to allow humans to survive without pressurized suits. The Second Crew Are we going, or nah? This gives researchers the ability to better understand the physical state that astronauts going to Mars would arrive in. Once on Mars, surface gravity is only 38% of that on Earth. The red planet will bring out lots of possibilities and might be helping in discovery of things, unknown to us. The next thing you'll know, there's a colony there!! While these will eventually wear out, additional orbiters with communication relay capability are likely to be launched before any colonization expeditions are mounted. Granted, they were much less capable than our own modern societies, but at the same time, their challenges were also much more manageable than the challenges to colonizing Mars, seeing as how they could theoretically maintain themselves through fishing and farming while also possessing potential lifelines in the form of regular contact with their home countries as well as contact with the friendlier Native Americans. [63], Mars requires less energy per unit mass (delta V) to reach from Earth than any planet except Venus. Some ideas of possible technologies that may be able to contribute to the actual terraforming of Mars have been conjectured, but none would be able to bring the entire planet into the Earth-like habitat pictured in science fiction.[55]. There is frozen water on Mars' surface which proves that life might have existed there billions of years ago. and Mars Direct, but in the end it takes time. A subreddit to make space colonization a reality.. We have a very liberal interpretation of that … Press J to jump to the feed. [62] As a result of the higher radiation in the Martian environment, the summary report of the Review of U.S. Human Space Flight Plans Committee released in 2009 reported that “Mars is not an easy place to visit with existing technology and without a substantial investment of resources.”[62] NASA is exploring a variety of alternative techniques and technologies such as deflector shields of plasma to protect astronauts and spacecraft from radiation. [109] In 2017, president Donald Trump promised to return humans to the Moon and eventually Mars,[110] effectively taking action by increasing NASA budget with $1.1 billion,[111] and mostly focus on the development of the new Space Launch System. The 20 Best Things to Do in Park City, UT for First Timers, A Traveler’s Guide to Hiking in Melbourne, Australia. Team Moon Kingdom. [45], Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. [102] Human explorers would also be vulnerable to back contamination to Earth if they become carriers of microorganisms. [81][needs update], Before any people are transported to Mars on the notional 2030s Interplanetary Transport System envisioned by SpaceX, a number of robotic cargo missions would be undertaken first in order to transport the requisite equipment, habitats and supplies. But there is a heating debate on whether we should colonize Moon or Mars. Although Earth is ideal living conditions for humans, scientists have studied the possibilities of colonization on another planet, Mars being that potential candidate. There is also risk of osteoporosis and cardiovascular problems. Space colonization on Mars can roughly be said to be possible when the necessary methods of space colonization become cheap enough (such as space access by cheaper launch systems) to meet the cumulative funds that have been gathered for the purpose. 3. Earth is similar to Venus in bulk composition, size and surface gravity, but Mars' similarities to Earth are more compelling when considering colonization. Mars colonization is possible in the distant future due to potential terraforming techniques and the presence of needed organic elements on Mars. Today, we know much more about Mars, but the ambitious missions imagined by the German engineer have never seen the light of day. Mars is the focus of much speculation and serious study about possible human colonization. Follow Mike Wall on Twitter @michaeldwall and Google+ .
