It is no secret that Mars became the name of the planet's top priority from some of what NASA is researching.

Moreover, the American Space Agency has found the water content contained in the surface of the Red Planet. Suddenly, speculation that Mars deserves human habitation sticks out.

Right or wrong, for sure or not, everything is still a big question mark until now. In fact, NASA is still trying to find a bright spot, is it true that the planet that has the moon Phobos and Deimos will be able to inhabit humanity in the future.

However, some researchers are optimistic that humans can stay on Mars in the future. Various steps were even prepared by NASA so that later the human colonization process on Mars could run smoothly.

However, with all kinds of technological support that is endeavored, is it true that later Mars could be a place worth living in humans to replace Earth?

Although it is still not clear, some researchers reveal the possibility of humans to live on Mars is still very minimal.

According to information reported by Time on Thursday (10/26/2017), there are several reasons that cause Mars to be impossible to inhabit. Most of these reasons come from the conditions, climate and ecosystem of the Red Planet itself. Here's the explanation.

1. Radiation

Mars described NASA researchers as having high levels of radiation. There are two dangerous radiation contents on Mars, including Solar Energetic Particles (SEPs) and Galactic Cosmic Rays (GCRs).

Both can bombard humans if not supported by adequate antiradiation devices while on Mars.

Further revealed, if humans inhabit Mars by spending around 180 days, then they will experience a 15 times increase in radiation.

2. Temperature

Temperature is one of the major obstacles for humans to be able to land on Mars. For information, the average temperature on Earth is around 57 degrees Fahrenheit (14 degrees Celsius).

However, the average temperature on Mars is at temperatures around -81 degrees Fahrenheit (-63 degrees Celsius) which is a temperature that is highly unlikely to make humans survive without the help of sophisticated tools.

If humans survive in the temperature of Mars with the help of tools that are so minimal for 68 days, they will certainly die.

3. Atmosphere

In addition to the radiation and temperature conditions, the atmosphere is also a concern for researchers. As a comparison of the atmospheric layer of the Earth 100 times more dense than the atmospheric layer of Mars.

Earth's atmospheric layer is made of 78 percent nitrogen, 21 percent oxygen and 1 percent gas collection.

Meanwhile, the atmospheric layer of Mars has 96 percent carbon dioxide which is very toxic to humans. The rest of the atmospheric layer contains a collection of argon, nitrogen and other harmful gases.

Gravity and Bacteria

Entering Maven into Mars orbit will be followed 48 hours later by Mangalyaan, India's first mission to the Red Planet.

4. Gravity

Although humans can outsmart the problem of gravity, this is still a consideration for researchers. The level of gravity on Mars is only 38 percent so that it can still be possible for humans to be able to walk on Mars.

The consideration is that humans will be feared that they cannot walk and move freely because they are limited by the level of gravity of the Red Planet.

While on Earth, the human body can accept the "One-G" gravity condition which is able to move skeletal, muscular, cardiovascular well.

5. Space Germs (Planet Bacteria)

Mars is not Earth. What is clear, ecosystems and microbial living things that exist on the Red Planet are very different when compared to Earth.

Researchers suspect that there are space germs that live on the air of Planet Mars.

Although it has not been investigated in depth, this has become one of the important issues. Given the events of the Apollo astronauts who had to be quarantined for 21 days because they were afraid of having space germs after returning from the Moon.

6. Infrastructure

Although Mars has been revealed to have the possibility to grow plants, this is in fact doubtful.

Martian temperature humidity is still difficult to control. If plants grown on Mars get excess oxygen, the risk of a large explosion will occur. Unfortunately, there are still few who consider this to be a serious matter.

7. Mental Conditions

This is the 'burden' of the astronauts if indeed they are deployed to fly on Mars. Eight months of traveling to Mars will certainly 'randomize' their mental condition.
