Venus is obviously closer to the earth, why do scientists prefer to go to Mars, which is farther away?

The reason why scientists would rather go to Mars is because Mars is more suitable for human survival. Compared with Venus' high temperature of more than 400 degrees, Mars' temperature of about 20 degrees is more suitable for the survival of people on Earth, and Mars humans need nitrogen to breathe. Venus is the closest planet to the Earth. It has many similarities with the Earth. It can be said to be the sister planet of the Earth. The radius of Venus is 6073 kilometers, which is only 300 kilometers smaller than the Earth. Its mass is also four-fifths of the Earth. It is very Close, the volume is 0.88 times that of the Earth.

Although Venus is very similar to the Earth, its conditions are particularly harsh. In fact, Venus is relatively small compared to the earth, but many conditions are very similar to the earth. This similarity is also extremely rare among many planets. When we first observed it, we found that there might be intelligent civilization on Venus. But they found that the conditions were extremely bad and not suitable for human habitation at all.

Venus not only has a high surface temperature, but also often has strong winds exceeding magnitude 17 on the surface. Humans cannot survive in such an environment. There are often strong winds exceeding level 17 on the surface of Venus. High temperatures, acid rain, and strong winds form a fiery red hell. When we look at Venus through an astronomical telescope, what we see is a planet that is burned red. Such a harsh environment, Human explorers are unable to land at all. The detectors orbiting Venus in outer space cannot see the surface of Venus very blurry because Venus is blocked by a thick layer of atmosphere.

Although Mars is farther away, its conditions are more suitable for human survival. Although Mars is not as close to the earth as Venus, nor is it as large as the earth or Venus, the conditions on Mars are much better than those on Venus. First of all, the temperature of Mars during the day can reach 20 degrees Celsius, which is a problem for the human body. The temperature is very suitable. Although the temperature at night reaches -139 degrees, I believe that human wisdom can overcome this temperature difference between day and night.
