Mars Colony Essay

Decent Essays
Attempting to establish a colony on Mars is a costly and research intensive endeavour. It will take a very special group of people to travel to Mars and spend their whole lives there. These volunteers will need to be very well trained. It will also take a lot of resources to sustain this colony, especially in its early days. If the target of 2025, which is only eleven years away, is to be met, a very large expenditure will need to be made on research due to our very limited understanding of how our bodies react to zero gravity and a far lower atmospheric pressure. The feasibility of this venture is very questionable. Even with the training they get, the volunteers will be faced with a whole range of medical problems caused by living in conditions …show more content…
Although this can be reduced selecting volunteers as healthy as possible, it is still a large amount of very expensive equipment. For example an MRI scanner usually costs around one million pounds. This equipment, as mentioned earlier, must be very advanced and a lot of research will be required to develop it. It will also cost millions of pounds to transport this equipment to the colony in Mars and to transport consumables such as food to Mars. Bottled oxygen will be required to sustain the astronauts and as a result will be used up very quickly. Water on Mars can be electrolysed to make oxygen using several redundant systems like on the international space station, but a backup for these systems in the event of failure or malfunction will be required. In the long term, terraforming is a solution. Changing the atmospheric composition on Mars will make it more habitable and eventually eliminate the need for bottled oxygen but this extremely research intensive activity could take thousands of years to achieve its desired end …show more content…
We already know what an extended time in zero gravity conditions does to the body. Muscle mass is reduced and people have difficulty walking when they return to earth. This is obviously a very basic understanding and we don’t even know what effect would lifelong exposure to zero or low gravity have on the human body. A possible way of doing this would be to send a different group of volunteers into orbit for an extended period of time such as ten years and monitor the effects of long term zero gravity. This would be a costly venture but feasible as it is relatively simple to resupply the group and return them to earth at the end of the mission. The long term effect of living in low atmospheric pressure will also be investigated in this mission. Although the astronauts will be wearing space suits, the atmospheric pressure on Mars is approximately 0.6 percent of that on earth which makes it not ideal for

    This ties directly into the opposition’s argument to fix the Earth. Why spend money delaying the inevitable death of our planet, when we could find a new planet that would alleviate the strain we’re putting on this one, solving both problems. Throughout the explorations to find a new planet, we’d most likely find other planets that are full of valuable resources. Space is seemingly infinite, which means there’s a very high chance there are places where we could harvest water, minerals, and even energy. A couple years ago NASA discovered a giant cloud of water out in space.…

    For example, the time to reach mars is almost 296 more days more than the time to reach the moon. Since we are not accustomed to this time, people can die of several things. Last, the spaceship speeding at mars will not have time to stop, with the technology we have now. For example, Mars atmospheric pressure is less than 1 percent of Earth’s, making it nearly impossible for the spaceship to slow at an estimated 13,000 mph. Since the speed is too fast, and not enough slowing, everyone in the spaceship will die.…

    The private space companies don 't have a lot of it. But unlike NASA, the private companies aren 't operating as many satellites, employing as many people, or operating as many facilities, so they could operate off donor money. But if somehow this money was to run out, the companies can bring NASA astronauts up, sell some of their patents, or sell their discoveries. Each space company could claim parts of each planet and attempt to build a habitat there. After their recent success of landing a rocket upright, Elon Musk, CEO of SpaceX said “This is a critical step towards establishing a city on Mars.…

    Furthermore, the rocketry type, (thermal rocketry) is the same from what we used over 50 years ago. The idea of thermal rocketry isn’t that bad, it’s the expenses associated with it. Some rockets use unimaginable amounts of fuel for missions closer to Earth than Mars. Multiple space companies have billions of dollars towards their development and are still asking for more, even though we could use that money for more pressing issues in our world. Even though STEM may not solve all of our problems, the results of what kind of people they are creating may.…

    Private companies can raise funds from investors, source supplies from anywhere, and avoid government inefficiencies. For example: the company SpaceX has proposed a rocket that will send humans to mars in just 1 launch, whereas the SLS would require multiple launches to send people to mars. Not only will it achieve the goal with less launches, the rocket will have a reusable design, further saving costs. This would be the most successful approach, but the least likely in the political battleground called…

    The modern times has seen even more NASA budget cuts and a rise in private contractors looking to space. The budget cuts may even be costing the US more than its saving them. A writer from the washington post says “Since the shuttle 's retirement, the United States has been forced to rely on Russia to take its astronauts to the station, an expensive and troubling arrangement that now costs $76 million per seat” (Davenport). There are multiple astronauts on the space station with multiple launches a year, the price of using rockets could severely add up. Most recently in the bid for cheaper space travel are the contracting of private corporations.…

    NASA estimates that a Mars mission would cost over $100 billion, although estimates vary greatly and reach as high as $500 billion . This NASA estimate would consume 38 percent of the United States annual budget, and would contribute to the United States’ unsustainable level of debt. Investing this money in other worthy causes like education, climate change, social welfare programs, and fighting the national debt would likely have more direct benefits to humanity than an expedition to Mars. Along with this financial infeasibility, NASA and other organizations currently do not have adequate technology. The technology to lift supplies into space is not yet fully developed, and furthermore, when Mars is on the far side of the sun, astronauts would face an extended period of time when astronauts without communication to Earth .…

    Although, Mars One may find the technology needed to build a bigger rocket, they will need more; to build another one for the people sent to Mars after the first group. This also proves that Mars One will need a better landing method because they want to land a huge rover onto the red planet, but they have not yet achieved that with one of the (huge) size they have in mind. Not only does Mars One need more technology to build bigger rockets and get a better landing method, it takes a lot of money; and Mars One already doesn’t have enough money. Mars One is not doing too well in this situation.…

    There are currently countless things that hinder mankind’s way of living; sickness, disease, food shortages, global warming, lack of space due to human expansion, but through the power of interstellar travel, it is possible that many of these unfortunate occurrences could become a thing of the past. Susie has cancer here on earth while the cure for his disease could be lying dormant on Mars’ surface. Without interstellar travel, mankind may never be able to aid those with crippling ailments, but with it the human race could potentially flourish and become healthier than its ever been. In fact, scientists have already discovered new, organic materials from different planets that may be able to save lives and improve the living conditions for many people around the world. Some may argue that mankind has everything needed right here on earth plus scientist don’t know all the things about planet earth so why try to learn about another or anything else in the universe.…

    Next, landing is nearly impossible. For example, Mars’ atmospheric pressure is less than 1 percent of Earth’s, making it difficult to slow a spaceship hurtling toward the surface at an estimated speed of 13,000 miles per hour. Unmanned rovers have cushioned their descents with heat shields, parachutes, and rockets, but current technology is insufficient for landing a much larger manned spacecraft. Since the spaceship would be going so fast there is a big chance everyone could die. Finally, oxygen, water, food, and movement.. All questions that are concerns.…
