"Climate change is already happening on our planet, and even if we were able to stop emitting greenhouse gasses right now, we would still continue to see some effects from it," Sohm said. Mars, on the other hand, has about 95 percent CO2, less than 3 percent nitrogen, less than 2 percent argon and only 0.2 percent oxygen. He not only enjoys the engineering challenge, but Donovan also believes rocketry has a lot to offer society. include the development of new materials, economic stimulation, culture, and global partnerships. An alternative to fully colonizing the planet is is a radical option called "terraforming Mars." The low gravity of Mars also poses a challenge to human colonizers. of 78 percent nitrogen, 21 percent oxygen, 1 percent argon and trace amounts of other gases, including CO2. The technology is still a long way from being realized. Mars also has much thinner atmosphere than Earth, which would have to change for humans to live comfortably on the planet. “Since 2010, NASA has been testing out the effects of what living in space can do to the human body, to prepare them for the journey to Mars, and also for living there” 9. SpaceX could definitely have the necessary communications instruments built and launched by the time the ITS is ready to go, but Musk and his team have yet to reveal any details on that front. Another problem with colonizing Mars is that it also implies significant levels of pollution. Mars has a much thinner blanket, so it rests at -81 degrees Fahrenheit. NASA has also conducting tests to see if we would be happy on Mars by putting humans in a “Mars-like” dome for a year and see if they react well to the situation 10 . This gets Musk out to improve costs by a magnitude of 4.5 — or roughly 31,000 times. Venturing to Mars is no exception. Photo from NASA Image and Video Library. In 2013, the SpaceX CEO. Musk and his private rocket company moved another step closer to their dream of establishing humans as a multi-planetary species, one they believe is key to the long-term longevity of our species. He wants to slash expenses by 50,000 times. Difficulties and hazards include radiation exposure during a trip to Mars and on its surface, toxic soil, low gravity, the isolation that accompanies Mars' distance from Earth, a lack of water, and cold temperatures. Musk suggest bringing large, powerful solar panels to the planet in order to generate the necessary energy. (Image: © by Karl Tate, Infographics Artist) With half the diameter of Earth, Mars has much lighter gravity (one-third of … These aren't impossible hurdles, but they will take some brainpower and some luck to solve. Radiation on the surface of Mars is more than twice the one experienced at the International Space Station. These circumstances will probably cause mental illness in at least some of the c… It is estimated that four such impacts would be sufficient to create Earth-like conditions on Mars. Pros: * We made it to another planet! BFR seeks to solve the first problem of how to get humans to Mars, but that is only the beginning of the colonizing Mars challenge. Solar particle events also occur without warning and bombard the place. A video later surfaced of the engine spewing a steady stream of bright-colored flame. Annenberg Media is a student-led multiplatform news media overseen and funded by the USC Annenberg School for Communication and Journalism. The low gravity of Mars also poses a challenge to human colonizers. “Mars is no place for the faint-hearted,” NASA reports. He and his team think they can achieve the production of methane using carbon dioxide in the atmosphere and water that’s already stored as water-ice. Lacking the levels of oxygen and nitrogen a human needs to breathe, and with far too much carbon dioxide, Martian air would quickly kill a human without proper equipment?. Accessing water, dealing with a frigid planet that lacks oxygen and coping with dangerous levels of radiation are among the biggest hurdles to overcome. Without outlining the kind of shielding that will be used on the ship — named Heart of Gold after the one in Hitchhiker’s Guide to the Galaxy — or any other methods to mitigate radiation exposure, Musk threw out mentions of pointing the rear of the rocket towards the sun to maximize shielding, and developing artificial magnetic fields to deflect high-energy particles. We haven’t found a type of shielding that provides enough protection that’s also light enough for Mars-bound spacecraft. "It has the potential to have been an abode of life." Musk hopes that one day a trip to Mars will cost about $200,000 a person. Raptor is the engine that will power both components. There is a lot of work to do. The root of the answer is that the scale of what a trip to Mars is incredibly big and complex. "Once [the rocket is] up there, you can't pull it back…There's no option for failure.". You're not losing much, and there's a lot to learn.". "I think that there are a lot of people who have the smarts, ambition and focus to solve our most difficult problems. "If you have an artificial gravity system that simulates the Mars gravity, the landing is easier.". Engineers constructing vehicles to carry humans to Mars attempt to account for this difference in their design. “…I do think it is worth researching the possibility, especially the basic science behind it. Future Mars exploration missions will present scientists and astronauts alike with a host of problem that will challenge human survival. The third is perhaps the most extraordinary: capturing large, nitrogen-rich asteroids, attaching engines to them, and flying them to Mars until they collide with its surface. The challenges are formidable. What is more than likely is that the Martian landscape will change dramatically from human behavior. The real wild card for long-term health is the low gravity. A successful liftoff is an accomplishment to be proud of, but surviving in Earth’s … Colonizing Mars — not to mention Terraforming it — is a difficult challenge. Others have discussed microgravity’s effects on the human body, but Mars is not free-fall. They would weigh on the order of 200,000 pounds, too large to create and launch from Earth. He’s banking on developing four pillars for the ITS: full reusability, refilling spacecraft in orbit, producing propellant on Mars with endemic resources, and using the right kind of propellant to achieve maximum efficiency. The committee categorized the hazards on Mars by their sources or causes. Not much is known, however, about living on a planet with reduced gravity, like Mars. Mentally, astronauts would be harm with loneliness, psychological issues since they will be coexisting with only a certain number of people. Coughs and colds. . That still quite shy of the $200,000 goal, but it’s a start. When a high-speed proton hits a water molecule in the upper atmosphere, the oxygen and hydrogen atoms in the molecule can be separated and the light hydrogen atoms can be swept away.”. "There is a lot of payback on the societal scale if you invest a lot of time and money. , has about 95 percent CO2, less than 3 percent nitrogen, less than 2 percent argon and only 0.2 percent oxygen. A. later surfaced of the engine spewing a steady stream of bright-colored flame. In the first, giant space mirrors would orbit the planet, reflecting sunlight back at Mars and heating it. Mars' weak gravity and magnetic field explain why it has not retained as much water as Earth. Several space explorer companies such as SpaceX, Mars One, 4Frontiers Corporation, Inspiration Mars Foundation, and the Mars Direct want a human being to set foot on planet Mars. Moreover, to say the risk of cancer is “minor” is wrong. Donovan and USC RPL aim to become the first student-run and led group to launch a rocket to outer space. "We do everything humanly possible and try to avoid human mistakes," says Naderi. Would building a colony on Mars populated by a million human beings violate this agreement? It is estimated that four such impacts would be sufficient to create Earth-like conditions on Mars. Space is another … "Astronauts have difficulty after being in space for a year adjusting to earth's gravity," said Gedi Minster, a master's candidate in Astronautical Engineering. The second is building greenhouse gas factories on the surface of Mars, using them to warm the Martian climate in a similar sense to how current fossil fuels are causing warming on Earth. You’ve already got a great answer from Haseeb that goes into the scientific details. Some benefits include the development of new materials, economic stimulation, culture, and global partnerships. “The magnetic field of the Earth diverts the flow of the solar wind (primarily protons) from reaching the atmosphere. Some might compare this philosophically to damming up the Grand Canyon to use as a reservoir on Earth.”, Donovan and USC RPL aim to become the first student-run and led group to. Because of their distance from Earth, real time interaction with people back home will be impossible – the shortest delay for sending transmissions will be about 10 minutes. The risks are also great. A number of planetary characteristics must be adjusted for human life to survive once it touches down: at a minimum, warmer temperature, breathable air, liquid water, and plant life. The second is building greenhouse gas factories on the surface of Mars, using them to warm the Martian climate in a similar sense to how current fossil fuels are causing warming on Earth. We know that long exposure to the zero gravity of space causes bones and muscles to deteriorate. Recently, Musk and his private rocket company moved another step closer to their dream of establishing humans as a multi-planetary species, one they believe is key to the long-term longevity of our species. Earth’s is. Musk wants someone to be able to get to the red planet for basically the cost of selling their house. He was enthusiastic about how the ITS is supposed to work, but a few things will get tricky, as he noted to those assembled at the International Astronautical Congress in Guadalajara, Mexico, on September 27. But Mars lost its magnetic field, which would have protected life from harsh radiation from space, 3.8 billion years ago. In theory, it would allow humans to transform Mars into a naturally habitable planet with characteristics like Earth. In fact, large amounts of fossil fuels and other resources have to be used to construct and to fuel rockets that have the potential to reach Mars. Consider that deep space radiation is probably killing former Apollo astronauts who went to the moon and back — people who spent less than two weeks in space. The Interplanetary Transport System could get us to Mars and beyond, but it would be just as flawed to say its foolproof. In the 80s and 90s, it was racing to land on Mars; however, due to some problems… I think this may be a feasible long-term option, but I think it would take years, maybe hundreds or thousands of years, to accomplish,” Banerdt said. Taxpayer-funded NASA can’t approve a mission that is unsafe past a certain threshold, while SpaceX, a private company, is unencumbered by those constraints. In turn, this also implies significant air pollution and may also contribute to … Elon Musk has big dreams for the future of human space exploration. The composition of Mars’ atmosphere is vastly different from that of Earth, so humans would have a hard time breathing. Get the latest updates on NASA missions, watch NASA TV live, and learn about our quest to reveal the unknown and benefit all humankind. This is not currently practical or sustainable. The higher gravity of the Earth essentially holds on tighter to the atmospheric gases, including water vapor,” said Bruce Banerdt, Principal Investigator on JPL’s InSight mission, which is currently studying the interior of Mars. Nobody knows. I’m going to base my answer on personal feelings and basic knowledge. And those are just the robotic ones! Cosmic radiation is a big deal, and it’s maybe the single largest reason NASA has not yet attempted a crewed mission to the red planet. "Space tech is the 'science of superlatives: the highest speeds, hottest hots, coldest colds, longest times,'" Donovan said. Part of Musk’s plan calls for generating spacecraft fuel on the surface of Mars itself, using resources already found on the planet. Lacking the levels of oxygen and nitrogen a human needs to breathe, and with far too much carbon dioxide, Martian air would quickly kill a human without proper equipment?. Living in the ship after arrival isn't just a SpaceX idea, though. But we should also think about the ethical implications of drastically changing a unique planet. Recently, Musk and his private rocket company moved another step closer to their dream of establishing humans as a multi-planetary species, one they believe is key to the long-term longevity of our species. Radiation: “Not too big of a deal.” Without outlining the kind of shielding that will be used on the ship … Earth and Mars only make it to the right orbital alignment for a Hohmann transfer to take place every 26 months for allowing a six-mont… Geological evidence suggests that prolific amounts of water used to flow across the surface, carving out characteristic patterns of rivers and lakes. If you catch a cold on Earth, you stay home and it’s no big deal. And that’s precisely why NASA is so keen on avoiding such a scenario until we know more about what the Martian environment is like. "And if we would need to transport some of those things from our planet to the other planet, then what is the point?". So living organisms may not have survived. The transfer orbit needs to be precisely timed so that when the spacecraft leaves Earth, it reaches the destination orbit at the same time that Mars reaches the same position. He not only enjoys the engineering challenge, but Donovan also believes rocketry has a lot to offer society. , humans will become a multi-planetary species in 2024, when SpaceX launches Starship to Mars. “Mars can’t just be a one-shot mission,” says Apollo 11 astronaut Edwin “Buzz” Aldrin, the second person to walk on the moon. It’s unclear how those panels will be brought to the planet, and if indeed they will be able to capture enough sunlight and turn it into electricity. Some might compare this philosophically to damming up the Grand Canyon to use as a reservoir on Earth.”. We know that long exposure to the zero gravity of space causes bones and muscles to deteriorate. When a high-speed proton hits a water molecule in the upper atmosphere, the oxygen and hydrogen atoms in the molecule can be separated and the light hydrogen atoms can be swept away.”, Terraforming scenarios revolve around increasing the temperature and atmospheric density of Mars, giving it breathable air, liquid water and temperatures conducive to human and plant life, and there are. In 2013, the SpaceX CEO said he wanted to die on Mars. In addition, Musk and others have stated that becoming a multi-planetary species is a necessary step in ensuring the long-term survival of the human species. Max Donovan, a junior Astronautical Engineering major who is a member of the USC Rocket Propulsion Lab (RPL) and will be interning at SpaceX this summer, said difficulty is inherent to the fields of rocketry and space exploration. main ideas for how to do this. “The higher gravity of the Earth essentially holds on tighter to the atmospheric gases, including water vapor,” said Bruce Banerdt, Principal Investigator on JPL’s InSight mission, which is currently studying the interior of Mars. "Mars is the most Earth-like of the planets in our solar system," says Naderi. Starship and Super Heavy are the two components of what is known as Big Falcon Rocket (BFR), which is a pseudonym for Big F****n’ Rocket, a 387-foot behemoth capable of taking 100 passengers to Mars. The planet's weak magnetic field means it is unable to retain as much gas around its surface. that in 50 years, humans could have a settlement of 1 million people on the red planet. “The magnetic field of the Earth diverts the flow of the solar wind (primarily protons) from reaching the atmosphere. Even on the surface of Mars, astronauts will be exposed to much higher-than-normal amounts of radiation due to the lack of a robust magnetic field on Mars. It’s about $10 billion to send just one person to Mars right now. One problem with living underground is that makes it difficult to communicate from one location to another, perhaps even between different lava tubes. We already know the first few Red Dragon missions will rely on NASA for communicating with Earth. When traveling to and living on Mars, human beings are going to have to adjust to some pretty bleak conditions. Annenberg Media is independent of the university administration. They would weigh on the order of 200,000 pounds, too large to create and launch from Earth. It’s unclear. Starship and Super Heavy are the two components of what is known as Big Falcon Rocket (BFR), which is a pseudonym for Big F****n’ Rocket, a 387-foot behemoth capable of taking 100 passengers to Mars. In the first, giant space mirrors would orbit the planet, reflecting sunlight back at Mars and heating it. A mission to Mars would take about six months. … Raptor is the engine that will power both components. Skeptics, however, question whether our time, money, and brain power could be better spent tackling the survival challenges facing earth’s current inhabitants. It’s no different for space pioneers. Conditions make living on the red planet extremely challenging. For the rest of their lives they will be able to interact directly with only their fellow colonists, who will increase from three people in the first two years to 23 people after 10 years. The international protocols of planetary protection prevent any nation or party in the world from seeding other worlds with life from Earth. The composition of Mars’ atmosphere is vastly different from that of Earth, so humans would have a hard time breathing. Terraforming scenarios revolve around increasing the temperature and atmospheric density of Mars, giving it breathable air, liquid water and temperatures conducive to human and plant life, and there are three main ideas for how to do this. The third is perhaps the most extraordinary: capturing large, nitrogen-rich asteroids, attaching engines to them, and flying them to Mars until they collide with its surface. “I think this may be a feasible long-term option, but I think it would take years, maybe hundreds or thousands of years, to accomplish,” Banerdt said.
