What is the reason why it is better for humans to aim Venus in front of Mars?

ByKev Lewis

The most hot topic in space development is "Mars exploration" no matter what. Although the development is being pursued with the aim of reaching the Mars of the humanity in the 2020's, the possibility that Venus may be more convenient for mankind than Mars is probably because the science-based YouTube channel "Life Noggin"It is explained in the movie.

The human race that reached the moon in the 1950s aims at Mars as the next destination.


NASA and SpaceX in the United States are cutting the leading edge of its development. Both of them aim to reach Mars in about 10 to 20 years.


However, it is also a fact that Mars has various barriers for humanity. Some scientists insist that human beings should aim Venus first, not Mars.


Mars exploration has been a challenge that has been held for more than 50 years, but as of 2018 it has not yet been successful. The reason is that it requires a large budget and development of sufficient technology has not been completed, but problems that can not be avoided are awaiting.


One of them is that the gravity of Mars is weak. The strength of gravity on the surface of Mars is only about 40% of the earth, which is believed to have various effects on the human body.


The main thing is the bad influence on muscle weakness and eyesight.


Also, because there is little air on Mars, the spacecraft is forced to maneuver difficult to landing while backfiring the rocket.


Furthermore, because there is no atmosphere, it can not shield the cosmic rays, so strong electromagnetic waves such as sunlines rain on the surface of Mars.


There is still a problem. The average temperature of Mars is 43 degrees Celsius, and when the temperature goes down, it may reach minus 125 degrees. In addition, it is waiting for a very harsh environment that the highest temperature never reaches 0 degrees.


Therefore, in order for mankind to live more safely on Mars, it is necessary to build something like a dome that covers the whole residential area with Supori and create an environment where air and temperature are more suitable for daily life.


But Venus, on the other hand, the temperature on the ground is 425 degrees Celsius and it is not in the environment where creatures can live very much. This is because having a very high carbon dioxide concentration atmosphere produces intense greenhouse effect. Also, there is no liquid water on Venus, rain of sulfuric acid is raining steadily, the atmospheric pressure of the surface is 90 atm, etc. It is impossible for living beings to live again.


It is said that human beings can live on such Venus is an altitude of 50 km from the earth's surface.


At this altitude, the strength of gravity is moderate, atmospheric pressure has the same 1 atm pressure as the Earth, and there is the advantage that the atmosphere cuts radiation falling from outer space.


Moreover, since the temperature at this altitude is around 30 degrees to 50 degrees Celsius, there is a high possibility that human beings can live.


NASA has adopted the concept "High Altitude Venus Operational Concept"(HAVOC) is announced in 2015.


In this concept, the two astronauts who sent in from the earth to the robotic airships that had been thrown in advance over Venus will enter and will actually live and collect data over the period of 30 days of the earth.


After that, we will introduce even more huge airships and make full-scale immigration. At this stage, "Venus in the sky" will be formed on Venus.


Although it is a living resident altitude 50 km altitude than Mars, it is not always possible to live in the same sense as the Earth. Since the atmosphere of Venus is mostly carbon dioxide, oxygen cylinders are essential.


In addition, a protective suit protecting the body from the rain of sulfuric acid is indispensable.


However, since atmospheric air contains carbon dioxide, nitrogen, hydrogen, and the like similar to the Earth, growing plants over Venus might make it possible to produce oxygen, fertilizer, and even water that is necessary for humans I do not.


The energy source of the air city is not only electric power from solar panels spread over the airship ... ...

While continuing to live in the sky, it may become possible to rebuild Venus' environment into a living environment by terraforming the environment.


However, among scientists, even if it succeeds in terraforming, if you calculate from the amount of hydrogen contained in the atmosphere of Venus, people who think that 80% of the planetary surface eventually becomes the ocean There are also things.


It is also thought that the environment changes drastically due to the impact of high-speed colliding objects.


Thus, although it seems to be said that "Mashi is better than Mars," it is certain that Venus' environment is quite a hurdle for humankind. Nonetheless, it seems that it seems quite attractive to the hibernation of "the aerial city of 50 km overhead".
