Venus and Mars are both located in the livable zone. Why did humans only land on Mars?

You know, human beings have been exploring the universe and even want to develop their own immigrant planet. To become an immigrant planet, they must meet the following requirements: the planet must be in a livable zone, that is, the position of the sun and the planet must be just right. Secondly, it must be a terrestrial planet with an environment similar to that of the Earth. Looking at the stars in the solar system, there are not many terrestrial planets, and even fewer meet the above two conditions.

Among the eligible planets, there are Venus and Mars. You should know the location of Jinxing, even better than the earth. At the same time, it is also the closest planet to the earth. Venus is almost the same size and mass as the earth, and its radius is only 300 kilometers smaller than the earth. It is recognized as the sister star of the earth. Among the Mayan civilizations found on the earth, there is a calendar about Venus. Due to the high civilization of the Mayans, many people speculate that the Mayans first lived in.

In fact, the planet's magnetic field is a prerequisite for survival. First, it is to resist solar radiation. Although the sun is far away from the earth, if there is no magnetic field on the earth, the sun will not be so gentle. Every day, solar storms have a great impact on human beings. Generally speaking, a planet without a magnetic field will not have an atmosphere, but Venus has a thick atmosphere. Most of the gases in the atmosphere are carbon dioxide and some sulfur dioxide, so the temperature of Venus is very high.

This is also an important reason why Venus cannot be used as an immigrant planet. Its temperature is really too high. You know, when people explore the solar system, the earliest goal is Venus, but Venus's thick atmosphere and harsh environment make it very difficult to land on Venus. The Venus rover can only exist on it for a few hours, and then it is completely paralyzed.

Mars, on the other hand, has a magnetic field and a thin atmosphere, and its rotation angle and gravity are very close to that of the Earth. Therefore, humans continue to launch Mars exploration satellites and instruments, and prepare for the next step by continuously collecting data. According to the latest news, humans will land on Mars in the next 20 years.
