It only takes 100 days to go to Venus and 286 days to go to Mars. Why don't people go to Venus?

Venus is the brightest natural celestial body except the sun and the moon. It is a bright star that twinkles in the western sky in the evening. In ancient times, it was called Chang Geng Star and Tai Bai Star, and sometimes it appeared in the east before dawn, which was called Morning Star.

Venus is also the closest planet to the earth, with the latest distance of only 38 million kilometers, which is 100 times the distance between the earth and the moon; Comparatively speaking, Mars, which is out of the orbit of the Earth, is about 55 million kilometers away from the Earth recently, so it is definitely easier to go to Venus than to Mars in terms of distance alone. Moreover, when going to Venus, it will be affected by the gravity of the sun, with a gravitational acceleration, while going to Mars will be dragged by the gravity of the sun, so going to Venus will save a lot of time and effort than going to Mars.

However, we often hear that some space powers in the world have explored Mars. Almost every country with space exploration ambitions has a Mars exploration plan. The media reports that China is also preparing to send a probe to Mars next year, but it is rarely heard that any country wants to explore Venus. What's going on here?

In fact, the reason is related to the exploration value of the two planets. Now people have realized that the surface environment of Venus is so bad that the detector can't stay on the surface of Venus for a long time. Therefore, Venus can only be detected in its periphery and atmosphere, which is of little significance and value in scientific research and utilization.

On the other hand, the probe can land on the surface of Mars and stay there for a long time. It can detect the atmosphere and soil composition of Mars on the surface of Mars, and even dig holes on Mars to detect the interior of Mars. Scientists also believe that in the future, humans can establish a closed base on the surface of Mars, engage in scientific research tasks on it, and even have the possibility of immigrating to Mars in the future. Therefore, the significance of detecting Mars is far greater than that of detecting Venus.

But this cognition was actually based on the long-term exploration of Venus by the United States and the former Soviet Union in the 1960s and 1980s, especially by the space department of the former Soviet Union. At that time, they were particularly inclined to explore Venus, because its mass and volume were similar to those of the earth, and its innate conditions were similar to those of the earth, so they once thought that there were probably creatures on Venus, so the former Soviet Union made more than ten explorations on Venus before and after. Later, I finally figured out some parameters and conditions of Venus, and found that its surface is extremely hot, the atmospheric pressure is also ridiculously high, the atmosphere is full of carbon dioxide, and there will be sulfuric acid rain in the air, which is not suitable for field exploration at all, so I finally gave up the exploration of Venus and began to explore Mars.

Through the exploration of Mars, it is found that the conditions of Mars are much better than those of Venus. Although the atmosphere of Mars is thin and the surface is cold, the temperature in the equatorial zone of Mars is not very low, and its surface is just like the desert Gobi zone on the earth. If humans establish a closed base on Mars, they can carry out scientific research and production activities on it, and even emigrate in the future. A planet with such scientific research value will certainly attract the attention of space powers.

In Mars exploration, the United States has always been at the forefront of the world. In addition, Russia, Europe, Japan, India and other countries have also explored Mars to some extent. It is reported that China will launch a Mars probe next year, opening the era of Mars exploration in China's space field.
