However, although the Ming Empire's exploration of Venus has experienced many failures, after more than ten years of efforts, there is some understanding of Venus, especially in the space near Venus, because Venus is much closer to the sun than the Earth, the temperature near Venus is naturally higher than that near the Earth, but it is still not as high as the surface temperature of Venus.

In addition, because the rotation speed of Venus is not fast enough, Venus itself has no magnetic field, and the resistance of the solar wind is very weak, so the entire process of the spacecraft flying to Venus is open with an electromagnetic shield, after all, if it encounters the solar wind, if the electromagnetic shield is not opened, then the spacecraft is very likely to be paralyzed on the way to Venus.

Although the spaceship can move forward at inertia, but because all the spaceships of the Ming Empire are now electrically driven, that is, driven by plasma thrusters, if the power of the spacecraft is damaged on the way, then the propulsion will not work, then the spacecraft can not be carried out whether it is turning, decelerating or accelerating, and the spacecraft can only fly forward at an inertial speed until the magnetic field of a certain planet is captured, and then crash directly on that planet.

This kind of thing is something that Zhu Lei, the Ming Empire and the staff on the spaceship itself don't want to see, although the spacecraft has been open with an electromagnetic shield, which consumes a lot of energy, but compared to safety, this energy consumption is nothing.

After the small spacecraft arrived at Venus, it did not immediately plunge into the return of Venus, but actually flew around Venus to collect data on Venus, although the Ming Empire sent a lot of probes to Venus before, but the probes are probes after all, and the main task of these probes is to collect data from the space area near Venus, and the data collection for Venus itself is actually very small, and the data to be collected by this exploration spacecraft for Venus is relatively complete. So the data collection began from the moment the spacecraft arrived near Venus.

In particular, the collection of the overall data of Venus, which is very important, after all, although it is possible that Mars will be the first to be modified by humans this time, and then it will be Venus's turn, but now the plan has not yet been determined, and the possibility of Venus being newly transformed is also very large, so it is necessary to be as detailed as possible for the careful collection of data, especially the overall data of Venus.

As the smaller the spacecraft stays near Venus, the more and more detailed data is collected, and although there is not much development on Venus, the data on the volume and weight of Venus itself has been collected in great detail.

Venus, as the second closest planet to the sun in the solar system, is only 0.275 astronomical units away from the sun, and Venus was called Chang Gung Star, Morning Star, Taibai Star or Taibai Star in ancient China, Venus in Roman mythology, and Aphrodite in Greek mythology.

The orbital period of Venus is 224.71 days, which is much less than that of Earth.

And Venus is also very bright, after all, as one of the closest planets to the Earth in the solar system, people can see it with the naked eye on Earth, and it is second only to the Moon in the sky at night.

Moreover, Venus is a terrestrial planet with a mass similar to that of Earth, so it is sometimes referred to as the sister star of Outer Earth.

And Venus is the only planet in the solar system that does not have a magnetic field, after all, Mars also has a magnetic field when it is found again, but Venus is not, and the orbit of Venus is also the closest to the prototype of all the planets in the solar system, with the smallest eccentricity, less than 0.7%.

And the size of Venus and the Earth is very close, the radius is about 6073 kilometers, only 300 kilometers smaller than the Earth, it can be said that the volume of the two stars is very similar, the volume of Venus is nearly 0.9 times that of the Earth, the mass is 4/5 of the Earth, and the average density is less than that of the Earth, although the environment of Venus and the Earth is very different.

After all, the surface temperature of Venus is very high, there is no liquid water, coupled with extremely high atmospheric pressure and severe hypoxia and other cruel natural conditions, so no matter what happens, Zhu Lei, in his previous life and in this life, all scientists believe that the possibility of life on Venus is very small.

Carbon dioxide is the most abundant in the atmosphere of Venus, which accounts for more than 97% of the atmosphere, so huge corrosive acid rain often falls on Venus.

So due to the room temperature effect, the temperature on the surface of Venus is as high as 500 degrees, and the atmospheric pressure becomes more than 90 times that of the Earth.

Venus, on the other hand, rotates from east to west, so if one were standing on Venus, the sun would rise in the west and set in the east.

The date of Venus's rotation is 243 Earth days, which means that Venus's rotation is longer than a year, and Venus's reverse rotation was in Zhu Lei's previous life, and most scientists believe that it collided with other asteroids to cause this.

After all, the retrograde rotation of Venus is very abnormal, and there is another point that the rotation period and orbit of Venus are synchronized, which is very abnormal for the scientists of the Ming Empire.

But after all, this world has not discovered this because the scientists of the Ming Empire do not know enough about Venus.

However, due to the temperature of Venus and other environmental reasons, neither the Earth in the previous life nor the Ming Empire in this world have exact information about the internal structure of Venus, but according to the available data, scientists have deduced that the structure of Venus should be similar to that of the Earth.

Because the magnetic field of Venus itself is very weak, it causes the solar wind to impact the atmosphere above Venus without hindrance, so Zhu Lei, a scientist in his previous life, thought that the water resources on Venus should be equivalent to the earth in the early days, but due to the solar wind, the water vapor on Venus is decomposed into hydrogen and oxygen, but because the weight of daily hydrogen is lighter and the mass is small, it escapes within the gravitational range of Venus.

There is no oxygen in the atmosphere of Venus, or the oxygen content is very low, so the surface of Venus is very dry, and the stones on Venus are harder than those of the Earth, which makes it easier to form all kinds of rock wonders.

In addition, according to the information sent back by the previous Ming Empire's probes landing on Mars, the magma on Mars contains water, so this data directly proves that Venus is likely to have a huge amount of water resources like the Earth, but these water resources have been evaporated.

In addition, the volcanic activity on Venus is also extremely frequent, in addition to hundreds of large volcanoes, there are more than 100,000 small volcanoes on the surface of Venus, so the magma ejected from the volcano forms a magma river on the surface of Mars, the strongest is more than 7,000 kilometers, which is also one of the biggest difficulties that the Ming Empire will face in transforming Venus in the future.
