The Big Barrier to the Idea of ​​Establishing Colonies on Mars: 'Radiation'

It is known that scientists who are working to find an alternative to Earth cannot find a planet whose conditions are suitable for life. Of course, there are those who come up with different ideas on this subject. Elon Musk comes first among these people. As an alternative to our planet, Musk proposes to colonize Mars. So is this possible? Let's look for an answer to this question together.


The fact that the conditions in the world are becoming increasingly inappropriate for life leads the researchers to look for alternatives. At this point, we can say that the idea of 'establishing a colony on Mars', which has been on the agenda many times in history, is still valid. So much so that many agencies, especially NASA, are continuing their research on the red planet.


Elon Musk is the most popular defender of the idea of ​​the Mars colony today . Musk, CEO of Tesla and SpaceX companies, expresses his dream on this matter at every opportunity. Musk, who was preparing to take concrete steps in this regard,  even proposed a credit system for those who did not have enough money but want to go to Mars . Aside from these moves of the successful entrepreneur, there is a serious obstacle to establishing a colony on Mars, according to the scientific world . Radiation is the name of this obstacle.


Although radiation is not the only obstacle to the Mars colony, it is an issue to consider:



Among the obstacles that must be overcome to establish a colony on Mars, there are obstacles such as atmosphere, temperature values, absence of water and similar natural resources, low gravity , but there is one issue that is taken into consideration when considering these issues that can pose serious problems. That's the radiation on Mars. 


Mars' rather thin atmosphere and lack of a strong magnetic field; causing a complex "particle radiation medium" to form on the planet . The fact that the particles coming with the solar winds interact with Mars is also an effective parameter in radiation.


As a group of researchers led by Donald M. Hassler stated in a study published in Science magazine in 2014, someone who traveled 360 days in space and spent 500 days on Mars is exposed to 1 Sievert (radiation measurement unit in SI unit system). According to studies, this radiation level increases the probability of a person getting cancer by 5% . Of course, it is worth remembering that this result is valid for 500 days and the effect on those who want to live on Mars for life can be terrible.


According to one study, 8 Sievert radiation means death:



According to researches, the person exposed to 8 Sievert radiation suddenly  faces death. We can say that it is difficult to reach 8 Sievert radiation levels on the planet where 1 Sievert radiation will affect every 500 days, but this does not mean that there is no risk of death. It is likely that the radiation level will be reduced with the space suits to be developed, but serious studies must be carried out for this.


We came to the end of our article, where we took a brief look at the radiation barrier in front of the Mars colony. If you are one of those who think that the idea of ​​the Mars colony is still viable after all these evaluations, you can share your ideas with us in the comments section.
