Pros of Colonizing Mars. As a result, the surface of Mars is exposed to solar flares always. [73], If one assumes carbon nanotube construction material will be available with a strength of 130 GPa (19,000,000 psi) then a space elevator could be built to land people and material on Mars. “But it also sounds a bit pie-in-the-sky.”, READ MORE: Humans Will Never Colonize Mars [Gizmodo], More on attempts to colonize Mars: 7 Ways to Die in the Future. Thus, we as humans will need plenty of patience since colonizing Mars is not an overnight project. Elon Musk, founder and CEO of SpaceX, outlined the company's plans to colonize Mars, speaking at the International Astronautical Congress meeting … [55][56] Occasional solar proton events (SPEs) produce much higher doses, as observed in September 2017, when NASA reported radiation levels on the surface of Mars were temporarily doubled, and were associated with an aurora 25-times brighter than any observed earlier, due to a massive, and unexpected, solar storm. [22] However, due to the much thinner atmosphere, a higher fraction of the solar energy reaches the surface. It is known however that an unborn child in space would be more susceptible to solar radiation, which would likely have a negative effect on its cells and genetics. Going to the geographic South Pole over a century ago was one of these expeditions. 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. Period. Wired systems might lay the groundwork for early crewed landings and bases, by producing various consumables including fuel, oxidizers, water, and construction materials. [32] 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 0.16% oxygen. Their plan is to organize a one-way trip of humans to Mars by 2027. Space motion sickness: Incidence, etiology, and countermeasures. How realistic is the method of colonizing Mars in Red Mars by Kim Stanley Robinson? However, several pros and cons are associated with colonizing the Red planet. These robotic systems also have a reduced cost compared with early crewed operations, and have less political risk. Shares.

There are 5 cities with large-scale domes now on Mars. The effect of long-term travel in interplanetary space is unknown, but scientists estimate an added risk of between 1% and 19% (one estimate is 3.4%) for males to die of cancer because of the radiation during the journey to Mars and back to Earth. The atmosphere on Mars has a very thin atmosphere and a very weak magnetic field. It would therefore be imperative, before any serious space colonization, to have global agreements in place, through the United Nations for example, that would determine the rules and codes of behavior. Colonizing Mars could be dangerous and ridiculously expensive. [23][24] The maximum solar irradiance on Mars is about 590 W/m2 compared to about 1000 W/m2 at the Earth's surface; optimal conditions on the Martian equator can be compared to those on Devon Island in the Canadian Arctic in June. Although there are no immediate prospects for the large amounts of money required for any space colonization to be available given traditional launch costs,[89][full citation needed] there is some prospect of a radical reduction to launch costs in the 2020s, which would consequently lessen the cost of any efforts in that direction. [39], Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. As with early colonies in the New World, economics would be a crucial aspect to a colony's success. Some early Mars colonies might specialize in developing local resources for Martian consumption, such as water and/or ice. Even a 5–8% decrease in total body water causes fatigue and dizziness and a 10% decrease physical and mental impairment (See Dehydration). They include: Proposed concepts for the human colonization of Mars. [3], SpaceX has proposed the development of Mars transportation infrastructure in order to facilitate the eventual colonization of Mars. ", "Teachers guide – Sunlight on mars – Tomatosphere", "Global warming and climate forcing by recent albedo changes on Mars", "Mars covered in toxic chemicals that can wipe out living organisms, tests reveal", "Toxic Mars: Astronauts Must Deal with Perchlorate on the Red Planet", "The adaptation potential of extremophiles to Martian surface conditions and its implication for the habitability of Mars", "Sustainable life support on Mars – the potential roles of cyanobacteria", "Higher, Farther, and Longer — Record Balloon Flights in the Second Part of the Twentieth Century", "How much water does an average person use? First he said he wanted to build an electronic payments company before the Internet was even popular. Scientists have also hypothesized that many different biological functions can be negatively affected by the environment of Mars colonies. Also due to the thinness of the atmosphere, the temperature difference between day and night is much larger than on Earth, typically around 70 °C (125 °F). [25], Global dust storms are common throughout the year and can cover the entire planet for weeks, blocking sunlight from reaching the surface. Mars Rush. 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). There is simply no way to do it at the present time. / Mars Colonization / Mars Colony. [102][120] In 2015, he stated "I think we've got a decent shot of sending a person to Mars in 11 or 12 years"(as in 2026–7). The mission architecture includes fully reusable launch vehicles, human-rated spacecraft, on-orbit propellant tankers, rapid-turnaround launch/landing mounts, and local production of rocket fuel on Mars via in situ resource utilization (ISRU). “People like to be optimistic about the idea of colonizing Mars,” Rachel Seidler, a University of Florida neuroscientist who’s studied microgravity, told Gizmodo. LANDING ON MARS. But what are the challenges and benefits of making Mars a "backup location" for humanity? Fuels or other energy source for use with surface transportation. Here are some key issues. Half of all water is used during showers. Earth based examples indicate that some should have lengthy passages offering complete protection from radiation and be relatively easy to seal using on-site materials, especially in small subsections.[95]. [116], One possible ethical challenge that space travelers might face is that of pregnancy during the trip. And microgravity can cause dangerous changes to the human body, especially when it’s faced with the challenges of reproduction. Mars City is expanded with two more domes of similar size and several smaller ones. In the former case, a trip time of forty days could be attainable,[68] and in the latter, a trip time down to about two weeks. MARIE found that radiation levels in orbit above Mars are 2.5 times higher than at the International Space Station. It is impossible to sterilize human missions to this level, as humans are host to typically a hundred trillion microorganisms of thousands of species of the human microbiome, and these cannot be removed while preserving the life of the human. Pros of Colonizing Mars. [48][49] On the skeletal system which is important to support our body's posture, long space flight and exposure to microgravity cause demineralization and atrophy of muscles. [98] There have been several planetary workshops on this issue, but with no final guidelines for a way forward yet. On earth, blood within the body stays 70% below the heart, and in microgravity this is not case due to nothing pulling the blood down. About 110 people would be needed to colonize Mars successfully, says a new report. [102][103] NASA had to deal with several cuts in funding. The Red Planet is a cold, dead place, with an atmosphere about 100 times thinner than Earth’s. And if we become extinct because we don't have a space program, it'll serve us right!» Ecological problems and lack of resources can lead to the extinction of humanity as a species. Colonization of Mars is a very real solution to the problem of overpopulation of the Earth. He speaks with Bloomberg's Emily Chang on "Bloomberg West." There are two main types of radiation risks to traveling outside the protection of Earth's atmosphere and magnetosphere: galactic cosmic rays (GCR) and solar energetic particles (SEP). 1. Elon Musk Will Sell All His Properties to Finance Colonization of Mars The richest man in the world plans to get rid of all his possessions on Earth to invest in building a city on the red planet. [71], Mars has a surface gravity 0.38 times that of Earth, and the density of its atmosphere is about 0.6% of that on Earth. Small outposts on Mars, he said, are a more realistic goal; full-scale settlements are at least another century away. Geothermal energy is also suspected in the equatorial regions. The pregnant woman and child would need additional nutrition from the rations aboard, as well as special treatment and care. 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. By Mike Wall 19 May 2020. Much remains to be learned about space radiation. During re-acclimation, astronauts were observed to have a myriad of symptoms including cold sweats, nausea, vomiting and motion sickness. Editorial for Episode 39 – Anarchist Colonization of Mars. So, yes, right at this very moment, colonizing Mars is totally unrealistic. ", Schuster, Haley, and Steven L. Peck. 2005;60(2):129-151. With a published price of US$62 million per launch of up to 22,800 kg (50,300 lb) payload to low Earth orbit or 4,020 kg (8,860 lb) to Mars,[90] SpaceX Falcon 9 rockets are already the "cheapest in the industry". [61] Initially, there was some evidence that this kind of low level, chronic radiation is not quite as dangerous as once thought; and that radiation hormesis occurs. Iron in this form is more easily extracted than from the iron oxides that cover the planet. Finally, someone has a realistic timeline for Mars colonization—the UAE The ruler of Dubai said humans should aim to colonize Mars a century from now. SpaceX’s Mars Plan: 2024. There is a big delay. ", lowest temperature ever recorded on Earth, Review of U.S. Human Space Flight Plans Committee, Variable Specific Impulse Magnetoplasma Rocket, President's Commission on Implementation of United States Space Exploration Policy, SpaceX Mars transportation infrastructure, "Humans don't have to set foot on Mars to visit it", "Elon Musk: Rockets will fly people from city to city in minutes", "Elon Musk shares images of "Moon Base Alpha" and "Mars City" ahead of IAC talk", "Barometric pressures on Mt. Colonizing Mars is a realistic goal if viewed in the right context. As far as I know, nobody has proposed a viable way to transport lots of people and supplies to Mars using existing technology (I think SpaceX is supposed to unveil a heavy-duty Mars … [50] Returning astronauts also felt disorientated. But on Mars, because the distance from Earth is so far (401 million km apart, at their greatest opposing positions) you don't have real-time controls. Reasons for colonizing Mars include pure curiosity, the potential for humans to provide more in-depth observational research than unmanned rovers, economic interest in its resources, and the possibility that the settlement of other planets could decrease the likelihood of human extinction. The lifetimes of these systems would be years and even decades, and as recent developments in commercial spaceflight have shown, it may be that these systems will involve private as well as government ownership. Mars, the Red Planet, has fascinated humans for centuries. Genetic engineering may be a big part of our future on Mars. "Political and Legal Challenges in a Mars Colony. Mars, the Red Planet, has fascinated humans for centuries. Starlight: Directed Energy for Relativistic Interstellar Missions. In 2003, NASA's Lyndon B. Johnson Space Center opened a facility, the NASA Space Radiation Laboratory, at Brookhaven National Laboratory, that employs particle accelerators to simulate space radiation. Sending humans to Mars is a phenomenal undertaking by all standards and presents very real risks and challenges. It is a little cold, but we can warm it up. In fact, there are already plans for Mars missions in the near future. [113][114][115], The predominant perspective of territorial colonization in space has been called surfacism, especially comparing advocacy for colonization of Mars opposed to Venus. Study: Collateral Damage from Cosmic Rays Increases Cancer Risk for Mars Astronauts, "Large solar storm sparks global aurora and doubles radiation levels on the martian surface", "Data Point to Radiation Risk for Travelers to Mars", "Space Radiation Hinders NASA's Mars Ambitions", "Technological Requirements for Terraforming Mars", "#21b, Flight to Mars: How Long? [46] In addition, Martian soil contains high levels of toxins which are hazardous to human health. Elon Musk wants to go to Mars. [citation needed], Mars has a weaker global magnetosphere as Earth does as it has lost its inner dynamo which significantly weakened the magnetosphere which is the cause of so much radiation reaching the surface despite its far distance from the Sun compared to Earth. The reduced gravity well of Mars and its position in the Solar System may facilitate Mars–Earth trade and may provide an economic rationale for continued settlement of the planet. Due to higher levels of radiation, there are a multitude of physical side-effects that must be mitigated. [51] Upon return to Earth, recovery from bone loss and atrophy is a long process and the effects of microgravity may never fully reverse. NASA’s Jet Propulsion Laboratory (JPL) collaborated with independent game studio Blackbird Interactive (BBI) to create an incredibly realistic interactive 3D Mars … Elon Musk wants to do it anyway. Since colonizing Mars would present such dangerous and challenging obstacles to human life, it is assumed that community laws on the Red Planet would likely be quite different from those on Earth. Elon Musk, the founder of SpaceX and Tesla, has released new details of his vision to colonize parts of the solar system, including Mars, Jupiter’s moon Europa, and Saturn’s moon Enceladus. Mars 2020 uses a lot of the same hardware as the Mars Curiosity rover, which landed on Mars in 2012. The atmosphere is also toxic as most of it consists of carbon dioxide (95% carbon dioxide, 3% nitrogen, 1.6% argon, and traces totaling less than 0.4% of other gases including oxygen). Perhaps more importantly, these storms affect electricity production from solar panels for long periods, as well interfering with communications with Earth.[16].
