Musk's plan to colonize Mars revolves around a large rocket, codenamed the BFR, which blasts a spaceship carrying up to 100 people into orbit before returning to the launch pad for an upright landing. Earth to Mars. LANDING ON MARS. But Musk believes it’s the other way around. Next, the colonists depart for Mars. NASA just safely launched its robotic Mars 2020 mission, but … 3. Having successfully landed on Mars you need air, water, food and power to survive. But just as settlers will be utilising local resources for water, food and energy, they will also hope to use local materials to build a larger colony or even spin-off colonies. Every step to establishing human civilisation on Mars is perfectly possible. © 2021 Forbes Media LLC. Within the next decade Nasa will finally have a spacecraft capable of making the journey to Mars. A child born under the red sky of Mars will have a very different outlook to one born on Earth and may never return to the home world – just as many descendants of European settlers in the US do not have passports. I'm an experienced science, technology and travel journalist and stargazer writing about exploring the night sky, solar and lunar eclipses, moon-gazing, astro-travel, astronomy and space exploration. Gear-obsessed editors choose every product we review. However, there is a fine line between a Star Trek-type command structure and a brutal military dictatorship, and as the settlement matures, some sort of democracy is going to be favoured. I mean really? Between the orbits of Mars and Jupiter lies the Solar System’s Main Asteroid Belt. “[Paypal cofounder] Elon Musk says he wants to go to Mars and I hope he’s successful,” said Hoffman. If humankind is to reach Mars, we will need rockets more powerful than anything built before (Nasa). From the desire to go there, to the consequences if we do, join us as we ask the question of what happens if we try and colonize Mars? It de-funds the International Space Station early in the name of getting to Mars. “A real society with real people living real lives, with children in schools and community orchestras.”. There is, however, a fundamental problem with trying to imbue Mars with a breathable atmosphere. Thanks to NASA's Kepler telescope, the answer to this question is yes. Evidence suggests that Mars was once awash with water – with lakes, rivers and oceans. For the sake of discussion I will define 'colonize' as the point in time at which a human lands on Mars to live out the rest of their natural life. The non-profit Mars Society has been experimenting with growing food in its isolated desert research station in Utah. Extracting water from urine and sweat through an efficient recycling system – pioneered on the International Space Station (ISS) – will certainly help, but will not be enough to sustain a community, so tapping into a local water source will be essential. Most prototypes of an interplanetary spaceship include solar sails and the ability to … All individuals to live under a dome (covered in a few meters of soil to protect the colonists from radiation) and share the same life support system. “It’s a small group of highly motivated people and it really doesn’t take much effort to manage them.”. The Earth’s atmosphere is contained within a magnetic bubble, known as the magnetosphere, generated by our magnetic field. To many people, space travel and colonization of another planet is exciting, a new adventure; though, many see it as the only way for humans to survive as we are using the natural resources the earth has at a faster rate than they can replenish. Simply staying alive will be a daily challenge. Fuel. But people are a different … well, animal, altogether. The massive new 2500 tonne SLS, combined with the Orion capsule, will enable astronauts to explore beyond the safety of low Earth orbit for the first time since the end of the Apollo Moon programme in 1972. Developing a vehicle that can both land and relaunch from Mars could take several decades to ... [+] perfect. All Rights Reserved, This is a BETA experience. “It’s certainly not a Star Trek-style military environment,” he says. We will begin by looking at the story of humans in space, discuss how SpaceX plans to colonize Mars with 1 million people and why it is such an important step for the future of humanity. Part 5- The Colonization of Mars So today we’re going to talk about Option #5-The colonization of the red planet, Mars. We can easily send robots to Mars, because their feelings don't get hurt if you forget to pack the oxygen and food. Those colonists that settle on Mars are unlikely to ever set foot on Earth again (Science Photo Library). At the very least, it would make sense to use Martian rock to bury the habitats to help shield occupants from radiation. What if a giant asteroid strikes Earth? In February, the Trump Administration released its $19.9 billion NASA budget. And in the video above, former astronaut Jeff Hoffman describes his project to bring oxygen to Mars. We spend most of our time thinking about how humans can live on Mars… Getty. How long do you think it will take humans to colonize Mars? In short: Mars needs bureaucrats. Spread the loveNovember 25, 2020 Technology Discussion: How Do We Address the Burgeoning Population? About 110 people would be needed to colonize Mars successfully, says a new report. Humans are heavy. Smith reckons that over generations a new culture would emerge, as humans become Martians rather than migrants. Today, we take a look at the largest asteroid/planetoid in the Main Belt – Ceres! The rocket then blasts off again carrying a fresh load of fuel for the transport ship. It seems plenty of people want to abandon the Earth. As for power, that should be relatively straightforward, with fuel cells and nuclear batteries augmented by solar arrays. Salotti’s calculations are based on the ability of a group of individuals to survive if cargo drops from Earth were stopped. For anyone looking to have healthy Martian children (see below), cosmic radiation could also harm sperm and eggs. Opinions expressed by Forbes Contributors are their own. These events can occur at any time, and they occurred in the past, many times. Life on Venus, Earth's sister planet. Colonization of Mars is a very real solution to the problem of overpopulation of the Earth. Getting to Mars though, will have an entirely different meaning: If we can get to Mars, we can go anywhere in the solar system. This “sharing factor” would be critical, says Salotti. Have children and establish a culture Assuming their sperm or eggs have not been zapped by cosmic radiation on the way to Mars (something space agencies are already giving serious thought to), then sooner or later a certain percentage of settlers are going to want to have kids. The early missions – particularly those involving space agencies – will almost certainly be run with a hierarchical command system. 5. ... How we test gear. A collective global inspiration emerged – if we could get to the moon, we could do anything. “At some point the Mars base breaks out of becoming a base and becomes an actual village,” he says. Build bigger spacecraft To support Kurzgesagt and learn more about Brilliant, go to https://www.brilliant.org/nutshell and sign up for free. The Orion capsule weighs almost 10 tonnes and that is before you factor in any service module or landing rockets. Nasa’s 2020 rover – essentially an upgrade of Curiosity – will carry an electrolysis experiment to extract oxygen from carbon dioxide in the Martian atmosphere. It’s a view shared by Zubrin. Related: Can we colonize Titan? The past history of the Martian atmosphere is currently being investigated by the Maven mission but, over the decades, any terraformed atmosphere is likely to suffer the same fate. At the moment, Orion is a relatively small spacecraft, but keeping astronauts alive and sane on … “It’s a hundredth of the scale we’ll need for a human expedition, but it’s a start.”. But now, Mars is not a life-friendly place. One question then remains: do you really want to go? The final figure is likely to be tens of billions of dollars, but Hoffman suggests that the new generation of entrepreneur billionaires who are “space nuts” might be part of a public-private solution. The agency is currently developing giant inflatable heatshields designed to slow spacecraft as they approach Mars, making landing larger craft feasible. Landing safely on Mars is also a challenge. It could also be extremely dangerous. Astronauts on the International Space Station (ISS) create water supplies from their own urine (Nasa/Getty Images), “It is going to be expensive,” he admitted. BBC Future World-Changing Ideas Summit in New York. “What it will take to finance the human exploration of Mars is hard to say.”. ... Mars Over the Moon. All the Reasons Why Humans Shouldn’t Colonize Mars, According to Experts. That figure is interesting. “One of the research projects we’ll be undertaking is to use the local rock as a growing medium by adding sufficient minerals and additives.” The idea is that, ultimately, colonists could grow crops in Martian soil. The moons of Saturn and Jupiter will seem like reasonable places to explore. You Only Need 109 Friends to Colonize Mars. Founder of SpaceX, which is working on … “We want a sustained human presence on … Colonists could use the rocks from the Red Planet's surface to help build shelters (Nasa). Tarvin is about to return to the Utah research station to take command and says a lot of progress has been made since then. We went to the moon over four decades ago, 15 years before anyone owned a computer, so it seems like Mars could have been perfectly doable by now—the limiting factor must be a lack of will. “If we’re going to have a long-term future in space, it won’t be done by a handful of astronauts, it’ll be whole communities,” he told BBC Future earlier this year. A government also needs all the structures that go with it. Do you think humans have the capacity to build an infrastructure on Mars that is reliable enough for a human to live out the rest of their natural life? Mars has aroused so much interest that private initiatives have been created to encourage colonization, like the Mars Society. It seems that we’re more likely to establish a base on the moon before Mars. Producing food on Mars could be much more difficult. Must we go to Mars to survive or can we have The Biosphere 2 project is an attempt to simulate Mars-like conditions on Earth (Science Photo Library), “For the very first time we’ll produce oxygen on the surface of Mars,” said Hoffman, who’s working on the instrument. Nevertheless, all these resources will need to be carefully managed, which is why the next step is so essential: I have written before of the challenges of governing an extraterrestrial colony. Cameron Smith, an anthropologist at Portland State University in Oregon, has suggested that a population of 2,000 would be sufficient to ensure long-term survival. NASA just safely launched its robotic Mars 2020 mission, but when it finally does send people to the “red planet” how many humans would need to live on Mars to create a successful self-sustaining colony? “People have grown some edible greens but it’s not at the stage we can live on what we produce,” he says. If setting up home on another planet sounds a daunting prospect, then our space correspondent Richard Hollingham is here to help. You may opt-out by. 2. Although any long duration mission is also likely to employ a habitation module, giving the crew a bit more room to move around in, the nine month trip to Mars is going to be uncomfortable and boring. About 110 people would be needed to colonize Mars successfully, says a new report. Right now, we have no idea how to protect astronauts from the dangerous levels of space radiation to which they would be exposed during a brief Mars vacation, let alone a permanent stay there. It might also be possible to extract useful minerals for metals or glass. Today, it is highly likely there is still water at the ice caps and possibly under the surface. Robert Zubin, the president of the Mars Society, is one of the leading exponents of terraforming Mars – transforming the planet from an airless, barren world to an oxygen-rich green and pleasant realm with a fully functioning ecosystem. Mars to Stay advocates recycling emergency return vehicles into permanent settlements as soon as initial explorers determine permanent habitation is possible. «The dinosaurs became extinct because they didn't have a space program. It could be one of the most important questions ever asked. We may earn commission if you buy from a link. Nasa used an innovative skycrane to lower its one-tonne Curiosity rover onto the surface in 2012. Make it simple: minimize the need for complex objects. Nasa is tooling-up for production of its new heavy launch vehicle, the Space Launch System (SLS), capable of conveying humans beyond Earth orbit; Mars One has recruited hundreds of volunteers for its reality-TV-funded one-way-trip to the Red Planet and the Mars Society is stepping-up its studies into what it takes to be a Martian. One objection that often gets raised when talking about … The past 50 years of human spaceflight have taught us that, in the extreme environment of space, this is the safest way. That could perhaps be because a colony is becoming too expensive to send cargo to, because of war on Earth, or because the colonists decide to go it alone and declare an independent Martian republic. NASA’s Journey to Mars: Pioneering Next Steps in Space Exploration. And if we become extinct because we don't have a space program, it'll serve us right!» Here are our five steps to building a new life on Mars: 1. The answer, according to a paper published in Scientific Reports, is about 110 people. It is, after all, the only way of perpetuating the colony over generations. And the ultraviolet level… If you would like to comment on this, or anything else you have seen on Future, head over to our Facebook or Google+ page, or message us on Twitter. It takes into account factors like how long the colonists would need to to spend mining, producing metal, ceramics and glass, chemicals and clothes, and recommends that colonists use three guiding principles: “If this relatively low number is confirmed, survival on another planet might be easier than expected,” writes Salotti. “We don’t approach Mars in terms of colonisation, [we’re] focused on expeditions in the long-run,” Hambleton explained. In real life on Earth, we can barely recycle plastic into reusable kinds of plastic. All this fascination is understandable since our neighboring planet has a series of characteristics that make it similar to our home. For it to be successful, the population needs to be large enough to avoid in-breeding over subsequent generations. After all, humanity could be threatened with extinction due to some cataclysmic event; global warming, a deadlier pandemic, all-out war on Earth, or an asteroid strike. Salotti thinks that producing new solar panels and new spacesuits would be a major challenge for the colonists that they would need to overcome. “A space colony is a tyranny-prone environment,” says Charles Cockell, an astrobiologist from the University of Edinburgh who is also leading research on developing a constitution for space habitats. Mars has no such field and any atmosphere it once had is likely to have been torn away by the stream of charged particles, or solar wind, blasted out from the Sun. We even have technology gurus who seem obsessed with colonizing the red planet. “If somebody gets control of oxygen, they could very well have control over the whole population and threaten dire consequences in return for extraordinary levels of power.”, As a commander of a space colony on Earth, Tarvin is one of the few people to have any experience of overseeing a Mars base. Develop step-by-step: accept harsh living conditions in the short term, accumulate resources, create new bases and new industries in order to achieve a modern society after a few centuries. Starship will enter Mars’ atmosphere at 7.5 kilometers per second and decelerate aerodynamically. If we're going to colonize a planet in another star system, we have to answer two questions. Interest in leaving the home world for a new start on Mars has never been greater and was one of the hot topics at the recent BBC Future World-Changing Ideas Summit in New York. It is not going to be easy. Or a deadly virus spread across the Earth? Plants will be grown in greenhouses, water will be extracted from ice, solar panels use for electricity and methane used to power engines. If we ever become—perhaps if we need to become—a multi-planet species, exactly how many settlers would be needed for survival on another planet? “The minimum number of settlers has been calculated and the result is 110 individuals.”. Read about our approach to external linking. “For the very first time we’ll produce oxygen on the surface of Mars,” said Hoffman, who’s working on the instrument. What we have is a way to go to Mars for an astronomical amount of money. The number of people that could be sent to another planet would be rather limited, says Jean-Marc Salotti at the Bordeaux Institut National Polytechnique, the author of “The Minimum Number of Settlers for Survival on Another Planet.”, “A mathematical model can be used to determine the minimum number of settlers and the way of life for survival on another planet,” writes Salotti. Why humanity should colonize Venus and how it can be done. It is easy to imagine that human civilisation on Mars is inevitable. Later, the surface could be drilled to form caves or rock could be excavated for building materials – just as we build houses from stone on Earth. NASA is developing the capabilities needed to send humans to an asteroid by 2025 and Mars in the 2030s goals outlined in the bipartisan NASA Authorization Act of 2010 and in the U.S. National Space Policy, also issued in 2010. “There was some interesting biology we were generating but not appetising biology,” says software engineer and Mars enthusiast Digby Tarvin of his last stint working at the base 10 years ago. And that’s no way to colonize Mars. Of course, we’d have to get to Mars in the first place . Not all of us have to go, we just need to send enough peopleto sustain a healthy population when something catastrophic happens on earth. Discover more ideas from the World-Changing Ideas Summit. Elon Musk: we must colonise Mars to preserve our species in a third world war This article is more than 2 years old.

I'm an experienced science, technology and travel journalist and stargazer writing about exploring the night sky, solar and lunar eclipses, moon-gazing, astro-travel. Getting there. Concepts of crewed Mars missions take about six months for between three and six astronauts to reach the planet, along with a few dozens of tons of consumables. SpaceX is currently working on its Starship, something of a reusable interplanetary spaceship that would be capable of sending 100 passengers at a time to Mars. Could Mars save the human race from extinction? Since we will not be encountering any sentient life forms on Mars, we do not have to worry about replicating the evils associated with colonization back on our own planet. Mars colonization is advocated by several non-governmental groups for a range of reasons and with varied proposals. Maximize sharing: everyone to share the dome’s ecosystem—air, water, food, energy, tools, spacesuits, vehicles and industries. It Will Drive Technological Change on Earth. One of the oldest groups is the Mars Society who promote a NASA program to accomplish human exploration of Mars and have set up Mars analog research stations in Canada and the United States. There’s no food, very little water, and no breathable atmosphere. Although it may be possible for some resources to be obtained from Mars—carbon dioxide from the atmosphere, water ice from the soil to produce oxygen and organic compounds, hematite to produce iron, silicates to produce glass—we’re decades away from understanding if any of that would be practically possible. With a focused effort it is very much doable. However, Salotti has doubts about reusability and thinks that developing a vehicle that can both land and relaunch from Mars could take several decades. I'm the editor of WhenIsTheNextEclipse.com and the author of "A Stargazing Program for Beginners: A Pocket Field Guide" (Springer, 2015), as well as many eclipse-chasing guides. To do so, first we need to consider the basic problem of radiation in the form of cosmic rays and solar activity. Any new society needs an economy as well as systems to maintain the habitat, provide employment, health, childcare, social care and education. In the short term you could rely on supplies brought from Earth or sent on supply missions but eventually you are going to have to produce your own. The summary of the video: 1. One of the big challenges will be growing food away from Earth (Getty Images). There is even evidence to suggest it may one day happen. Quite apart from the risks of launch (the recent Antares rocket explosion proves we should never take this for granted), during the transit to Mars the crew will be exposed to damaging levels of radiation that will significantly increase their risks of developing cancer. First, do any Earth-like planets even exist outside of our solar system? The first Mars settlers will be living in the capsules they arrive in, perhaps augmented by a few extra capsules sent ahead and maybe some inflatable domes. Mars is a bleak, cold, airless, rust-stained world. A Mars voyage requires a spacecraft that can carry multiple people, along … However, before you put all your worldly possessions on eBay and sign-up for a new start in Gale Crater, it is worth considering the obstacles that have to be overcome to build a sustainable extraterrestrial colony. The vehicle’s heat shield is designed to withstand multiple entries, but given that the vehicle is coming into Mars’ atmosphere so hot, we still expect to see some ablation of the heat shield (similar to wear and tear on a brake pad). The good news is that getting to Mars in one piece is essentially an engineering challenge but, speaking at the BBC Future World-Changing Ideas Summit, former Nasa astronaut Jeff Hoffman put his finger on a far bigger issue.
