Should We Colonize Mars

How would we colonize the Mars in our generation?

Mars colonization means that we should send some normal people (enough for reproduction, at least 100 people), land on Mars and live in Mars. This is a similar process with what we have done in America. Our journey to Mars is truly difficult. Until now, we have or had 12 spacecraft orbit and 12 spacecraft land on Mars, but half of our mission failed on the journey to Mars (data from NASA). However, we are still incessant trying to get the gate of the Mars. The idea that to colonize Mars is from some science fiction novels. Then, after we have the technology to get out of our Earth, it started to become our aim. The ultimate goal is not only make human land on Mars, but including Mars colonization

Because of the long time journey (about 200 days, depends on which year we launch), keeping healthy is a huge problem for astronauts and we should deal with it. There is no gravity in space human will lose muscles mass and calcium in bones long time in space. On the contrary, the last century, we never think about building an artificial gravity in space, many people just think it’s a scientist fiction. And also, most of scientists claimed since there is no gravity, human could not live in space for such a long time. However, right now, artificial gravity is easily to reach, and it’s not a science fiction anymore. We can spin the spaceship, just like the technology in "Star Trek", to create a one g centripetal force. Two space ships on the two sides attach with a long cable and revolve around the center. This device will allow the astronauts to spend most of their time in gravity. Second is the radiation. People receive a lot of radiation long time in space which would cause risk of the cancer (because we don’t have the protective magnetic field of our planet). So, we need to cover the spaceship with the material that can absorb radiation. One material can be the potential candidate for this job – hydrogenated BNNTs (Hydrogenated boron nitride

However, don’t forget, this step is not mean we have colonized the Mars. This is just the first step on the road we colonize the Mars. Consequently, when the first team of humans land on Mars, what should they do on Mars to prepare for next step? Our priority is to ensure they have enough food and water until next mission arrives. The most important thing is testing whether food could be plant in Martian soil. Because when we start to colonize the Mars, we are going to eat on Mars. Scientists are arguing for whether we can grow plants on Mars for several decades, and until now they don’t have a unanimous answer. A research group from Netherlands did a simulation research on Earth in 2014 to test whether it could be possible. In the research, the team planted fourteen different plant species in Earth, simulated Martian and lunar soils and compared the survival rates. The result shows although plants lack some reactive nutrients in simulated Martian soils, many of the plants grew better than some plants on nutrient poor Earth soil, and “80% of the tomato, rye, carrot, and garden cress plants were alive in Martian soil at the end of the study” (data from Wageningen UR). However, an article from “blooming plants” website questions about the possibility growing plants on the Mars. The first thing is the temperature. At the Martian night the temperature would fall to -73°C (99°F), killing
